TMJ Surgery: When Is It Actually Necessary? (2026 Guide) article.

By Dr. Sarah Mitchell, DDS·

TMJ surgery is rarely the first treatment option — and for good reason. The temporomandibular joints are among the most complex joints in the human body, controlling jaw movement for speaking, chewing, and swallowing. Most people with TMJ disorders respond well to conservative, non-surgical treatments. But in a minority of cases where structural damage is confirmed and pain is severe and persistent, surgery becomes a necessary and appropriate option. Understanding when that line is crossed is critical to making the right decision for your health.

If you have been diagnosed with a TMJ disorder (TMD) and your dentist or oral surgeon has mentioned surgery as a possibility, you likely have many questions — and valid concerns. This guide walks you through everything you need to know: when surgery is actually warranted, the different surgical options available, what recovery looks like, the risks involved, and the conservative alternatives worth exploring first.

Understanding TMJ Disorders and When Surgery Enters the Conversation

The temporomandibular joints (TMJ) connect your jawbone to your skull on both sides of your head. These bilateral ball-and-socket joints — unique in being the only frequently moving joints in the skull — allow the jaw to open, close, and move sideways, forward, and backward. When something disrupts the harmony of this system, the result is a temporomandibular disorder (TMD).

TMD symptoms vary widely but commonly include jaw pain or tenderness, clicking or popping sounds when opening or closing the mouth, jaw locking (in either open or closed position), difficulty chewing, facial pain, headaches, and sometimes ear-related symptoms such as ringing (tinnitus) or a feeling of fullness in the ear. According to the National Institute of Dental and Craniofacial Research (NIDCR), TMD affects approximately 5-12% of the US population, making it more common than many people realize.

The vast majority of TMD cases — somewhere between 70-90% depending on the study — are managed successfully without surgery. Conservative treatments such as night guards, physical therapy, medications, and lifestyle modifications form the foundation of first-line care. Surgery enters the picture only when these approaches have been thoroughly attempted and have failed to provide adequate relief, and when imaging or diagnostic testing reveals a structural or mechanical problem that cannot be corrected any other way.

It is worth noting that the decision to pursue TMJ surgery is not made casually. A qualified oral and maxillofacial surgeon — often working alongside a multidisciplinary team that may include a neurologist, physical therapist, and pain management specialist — will carefully evaluate imaging studies (typically cone beam CT scans or MRI of the joint), review the patient's history, and assess the severity and impact of symptoms before recommending any surgical intervention.

The Two Main Categories of TMJ Surgery

TMJ surgeries generally fall into two broad categories based on the philosophy of surgical approach: joint-preserving procedures and joint-destructive procedures.

Joint-preserving procedures aim to repair, clean, or reposition the existing joint structures without removing or replacing parts of the joint. These include arthrocentesis, arthroscopy, and some forms of arthroplasty. The goal is to restore normal joint mechanics while maintaining the patient's natural anatomy for as long as possible.

Joint-destructive procedures involve removing or replacing parts of the joint that are damaged beyond repair. These include condylectomy (removal of the mandibular condyle head), diskectomy (removal of the articular disc), and total joint replacement. These procedures are typically reserved for the most severe cases — often involving degenerative arthritis, failed previous surgery, or structural joint destruction from trauma or disease.

Understanding which category a procedure falls into matters because it reflects the severity of the underlying condition. Surgeons almost always attempt joint-preserving approaches before moving to joint-destructive ones, following what is known as a "least invasive first" surgical philosophy.

Procedure TypeCategoryInvasivenessTypical Indication
ArthrocentesisJoint-preservingLeast invasiveAcute joint inflammation, early internal derangement
ArthroscopyJoint-preservingMinimally invasiveInternal derangement, adhesions, inflammation
ArthroplastyBothModerate to openStructural damage, ankylosis, advanced internal derangement

Arthrocentesis: The Least Invasive Option

Arthrocentesis — sometimes called TMJ lavage — is the least invasive surgical procedure for TMJ disorders. It involves the insertion of one or two needles into the affected joint space to wash out the joint with sterile saline solution. The procedure is performed under local anesthesia or light sedation, and it typically takes 15-30 minutes.

How it works: The surgeon inserts needles into the joint space and irrigates the joint with saline, sometimes combined with a corticosteroid or hyaluronic acid injection at the end of the procedure. This flushing action helps remove inflammatory byproducts, reduces joint pressure, and can help dislodge a displaced articular disc that may be causing clicking, locking, or pain.

What it can treat: Arthrocentesis is most effective for patients with acute TMJ pain that has not responded to conservative care, particularly when there is evidence of joint inflammation or early-stage internal derangement. It is also used diagnostically — if pain is relieved temporarily after the procedure, it confirms that the joint itself is a significant pain source.

Effectiveness: Studies have shown arthrocentesis to be effective in 70-90% of appropriate cases, particularly for reducing pain and improving jaw opening. However, it is not a permanent solution for everyone, and some patients may require repeated procedures or progression to more invasive surgery.

Recovery: Recovery from arthrocentesis is relatively quick. Most patients return to normal activities within 1-2 days, though the jaw may feel sore and stiff for a few days to a week. A soft diet is typically recommended for 1-2 weeks.

Arthroscopy: Minimally Invasive Joint Surgery

TMJ arthroscopy is a minimally invasive surgical technique in which a small fiber-optic camera (arthroscope) is inserted through a small incision in front of the ear canal. This allows the surgeon to visualize the internal structures of the joint on a monitor and perform specific surgical manipulations through a second small portal.

How it works: The arthroscope — typically 1.8 to 2.0 millimeters in diameter for TMJ use — is introduced into the upper joint space (the space above the articular disc). Through a second portal, the surgeon can introduce instruments to cut adhesions (fibrous bands of scar tissue), irrigate the joint, biopsy tissue if needed, or reposition the disc.

What it can treat: Arthroscopy is useful for diagnosing and treating internal derangement (particularly Wilkes stage II-IV), removing adhesions that limit jaw movement, treating inflammation within the joint, and in some cases repositioning a displaced disc. It has largely replaced open surgery for many indications because it achieves comparable results with significantly less morbidity.

Effectiveness: Research published in the Journal of Oral and Maxillofacial Surgery indicates that arthroscopy has a success rate of approximately 75-85% for appropriate candidates, with significant reductions in pain and improvements in jaw function. It is considered a highly effective middle-ground option between conservative care and open surgery.

Recovery: Most patients recover within 2-4 weeks after arthroscopy. There is typically some swelling, bruising, and jaw stiffness in the first few days. A liquid-to-soft diet is required for 2-4 weeks, and patients are often instructed to perform gentle jaw exercises to prevent adhesions from reforming.

Open Joint Surgery (Arthroplasty)

Arthroplasty refers to open joint surgery in which the surgeon accesses the TMJ through an incision made in front of the ear and sometimes extending around the earlobe. Unlike arthroscopy, this approach provides direct visualization of the joint structures and allows for more extensive surgical manipulation.

How it works: The surgeon makes an incision, retracts the soft tissues, and exposes the joint capsule. Depending on the procedure, this may involve removing bony growths (osteophytes), reshaping the condyle head, repairing or removing the articular disc, removing scar tissue, or reconstructing joint surfaces. The specific manipulation depends entirely on the underlying pathology identified through pre-surgical imaging.

What it can treat: Arthroplasty is used for a range of conditions including advanced internal derangement (Wilkes stage IV-V), ankylosis (fusion of the joint), condylar resorption, benign joint tumors, and in some cases of traumatic joint damage. It is more invasive than arthroscopy or arthrocentesis but provides access to problems that cannot be addressed through smaller portals.

Effectiveness: Open arthroplasty has good long-term outcomes when performed on appropriate candidates. Studies suggest 70-80% of patients experience meaningful pain reduction and improved jaw function at 5-year follow-up, though outcomes vary significantly based on the underlying diagnosis and the patient's age and overall health.

Recovery: Recovery from open joint surgery is more demanding than from minimally invasive procedures. Initial recovery takes 3-6 weeks, during which patients must follow a strict soft or liquid diet and a rehabilitation program. Full recovery — including return to normal jaw function and strength — can take 3-6 months. Some temporary facial nerve weakness (numbness or weakness in the cheek, lip, or forehead on the surgical side) is common and usually resolves within several months.

Joint Replacement Surgery

When the TMJ is severely damaged beyond repair — whether from end-stage degenerative arthritis, failed previous surgeries, advanced osteonecrosis (bone death), trauma, or tumor resection — total joint replacement may be the only surgical option that can restore function and relieve pain.

Types of joint replacement: There are two main categories — alloplastic (artificial prosthesis) and autologous (using the patient's own tissue). Alloplastic replacement uses a titanium or cobalt-chrome prosthesis that replaces the mandibular condyle and often the fossa (the socket part of the joint). Autologous replacement uses the patient's own tissue — typically a rib graft or fibula graft — to reconstruct the joint.

Alloplastic total joint replacement is the more common approach today. FDA-approved TMJ total joint replacement systems (such as those from Zimmer Biomet or TMJ Concepts) consist of a condylar component that replaces the head of the mandibular condyle and a fossa component that lines the temporal bone socket. These devices are custom-fabricated for the patient's anatomy using pre-operative imaging.

What it can treat: Total joint replacement is reserved for the most severe TMJ conditions, typically after multiple other surgeries have failed. Candidates generally have advanced degenerative joint disease with severe pain and functional limitation that significantly impairs quality of life.

Effectiveness: Total joint replacement has the highest satisfaction rates among TMJ surgeries for end-stage disease, with studies reporting 80-90% of patients experiencing meaningful pain relief and functional improvement. However, it is major surgery with significant risks, and the prosthetic joints have a finite lifespan, meaning revision surgery may be needed in younger patients.

Recovery: Full recovery from total joint replacement typically takes 6 months to a year. The immediate post-operative period involves significant swelling, pain management, and a strict liquid diet for several weeks, transitioning to soft foods for several months. Physical therapy is essential for restoring jaw function, and patients must commit to long-term follow-up with their surgical team.

Who Is a Candidate for TMJ Surgery?

Not every TMJ patient is a candidate for surgery, and not every surgical candidate needs the same procedure. The surgical decision is made through a careful, multi-step evaluation process.

Step 1: Failure of Conservative Treatment

Before surgery is even considered, a patient must have completed a thorough trial of conservative care. This typically means 6 months or more of treatment that may have included:

  • Custom-fitted oral splint or night guard
  • Physical therapy with jaw-specific exercises
  • Medications (NSAIDs, muscle relaxants, anti-inflammatory drugs)
  • Dietary modifications (avoiding hard, chewy, or crunchy foods)
  • Stress management techniques (to reduce teeth grinding and jaw clenching)
  • Heat or cold therapy
  • Corticosteroid or hyaluronic acid injections

If these interventions have not produced meaningful improvement, the patient and treating clinician can begin discussing whether surgical options are appropriate.

Step 2: Confirmed Structural Pathology

Surgery is only considered when diagnostic imaging reveals a structural or mechanical problem that correlates with the patient's symptoms. This typically requires one or more of:

  • Cone Beam CT (CBCT) scan: Provides detailed 3D imaging of the bony structures of the joint, revealing condylar erosion, osteophytes (bony growths), fractures, or arthritic changes
  • MRI of the TMJ: Shows the articular disc position, disc morphology, joint effusion (fluid in the joint), and soft tissue pathology. MRI is considered the gold standard for evaluating disc displacement
  • Diagnostic arthrocentesis (as a test): If joint irrigation temporarily relieves pain, it confirms the joint as a pain source

Conditions that are commonly confirmed through imaging and may lead to surgical recommendation include:

  • Wilkes classification III-V internal derangement: Disc displacement with or without reduction, often accompanied by clicking, locking, and pain
  • Ankylosis: Bony or fibrous fusion of the joint, preventing normal jaw movement
  • Degenerative arthritis: Cartilage breakdown and bone-on-bone contact causing pain and crepitus (grinding sensation)
  • Condylar resorption: Progressive loss of the condylar head, leading to bite changes and facial deformity
  • Traumatic joint damage: Fractures, dislocations, or soft tissue injuries from accidents
  • Benign tumors or cysts affecting the joint structures

Step 3: Severity and Impact on Daily Life

Even with structural damage confirmed, most surgeons require that the symptoms significantly impact the patient's quality of life before recommending surgery. This includes:

  • Persistent, severe pain that interferes with sleep, work, or daily activities
  • Jaw locking that prevents normal eating or speaking
  • Significant nutritional compromise due to inability to chew
  • Depression, anxiety, or distress related to chronic pain

Who Is NOT a Candidate

Patients who have only tried conservative care for a short period, those whose imaging shows no clear structural abnormality, and those whose symptoms are primarily muscular rather than joint-based are generally not appropriate surgical candidates. Patients with widespread pain conditions (such as fibromyalgia) or significant psychological factors contributing to their pain experience may also be poor candidates, as surgery is unlikely to resolve symptoms driven by central nervous system sensitization.

The TMJ Surgery Recovery Timeline

Recovery from TMJ surgery depends heavily on the type of procedure performed. Below is a general timeline to help set expectations.

Arthrocentesis Recovery

  • Days 1-3: Soreness, swelling, and jaw stiffness are common. Over-the-counter or prescribed pain medication is typically needed.
  • Days 3-7: Swelling decreases, and jaw opening begins to improve. Soft diet continues.
  • Weeks 1-2: Return to normal daily activities. Gentle jaw exercises may be introduced.
  • Ongoing: Some patients benefit from follow-up injections or a short course of physical therapy to maintain gains.

Arthroscopy Recovery

  • Days 1-7: Significant swelling and bruising around the ear area. Jaw exercises are typically started within the first few days to prevent adhesions.
  • Weeks 1-4: Swelling gradually resolves. Soft diet continues. Most patients return to desk-work jobs within 2-3 weeks.
  • Weeks 4-8: Progressive jaw opening exercises help restore range of motion. Crunchy foods should still be avoided.
  • Months 2-6: Full recovery is typically achieved by 6 months, with continued improvement in jaw strength and function.

Open Joint Surgery / Arthroplasty Recovery

  • Weeks 1-4: Significant swelling (peaking around days 3-5), pain, and dietary restrictions. Liquid diet for the first 2 weeks, transitioning to soft foods. Facial nerve weakness on the surgical side is common.
  • Weeks 4-8: Swelling substantially reduced. Physical therapy begins. Soft diet continues. Many patients can return to desk work by week 3-4.
  • Months 2-6: Progressive jaw rehabilitation. Range of motion improves. Some patients continue to experience intermittent soreness during this period.
  • Months 6-12: Full rehabilitation. Strength and jaw function typically normalize by 12 months.

Total Joint Replacement Recovery

  • Weeks 1-6: Major surgery with significant swelling, pain, and dietary restrictions. Strict liquid diet for at least 3-4 weeks. Facial nerve symptoms are expected and may take months to resolve.
  • Months 2-6: Transition to soft foods. Aggressive physical therapy to restore jaw opening and function. Return to desk work may be possible by weeks 4-6.
  • Months 6-12: Continued physical therapy. The vast majority of patients achieve functional jaw opening and significant pain relief by the end of the first year.
  • Year 1+: Long-term follow-up with annual imaging to monitor prosthesis condition. Some patients will eventually need revision surgery, particularly younger patients whose prostheses may wear out over decades.

Risks and Complications of TMJ Surgery

As with any surgical procedure, TMJ surgery carries risks. Understanding these risks is an essential part of the informed consent process.

General Surgical Risks

  • Infection: Any surgical procedure carries a risk of infection. This is managed with sterile technique and, in some cases, prophylactic antibiotics.
  • Bleeding: The TMJ area is vascular, and some bleeding during and after surgery is expected. Significant hemorrhage is rare but possible.
  • Anesthesia risks: Risks associated with general anesthesia or sedation, particularly in patients with underlying medical conditions.

Procedure-Specific Risks

Nerve damage is the most commonly reported complication of TMJ surgery, particularly with open joint procedures. The facial nerve (which controls facial expressions and some sensation) runs in close proximity to the surgical field. Temporary facial nerve weakness — manifesting as asymmetry of the face, difficulty raising the eyebrow, or numbness in the cheek or lip — occurs in a significant percentage of open TMJ surgery patients and typically resolves within 3-12 months. Permanent nerve injury is uncommon but possible.

Altered sensation around the ear and in the distribution of the auriculotemporal nerve (a branch of the trigeminal nerve) can cause numbness, tingling, or hypersensitivity in the cheek, temple area, or ear. This may be temporary or permanent.

Hearing changes can occur due to swelling affecting the ear canal or middle ear structures, or due to damage to the nerve supply to the middle ear. Most hearing changes are temporary, but some patients report persistent tinnitus or muffled hearing after TMJ surgery.

Scarring around the surgical site is another consideration, particularly for open procedures. Surgeons take care to place incisions in natural skin creases where possible, but some visible scarring may result.

Bite changes can occur after any TMJ surgery, particularly if the condyle is altered or removed. This may require subsequent orthodontic treatment or bite adjustment.

Failure to relieve symptoms is perhaps the most important risk to understand. Despite a technically successful surgery, some patients continue to experience pain or functional limitations. The underlying pain mechanisms in TMD are complex and not always fully addressed by surgical correction of joint structures. Research suggests that approximately 15-25% of TMJ surgery patients experience inadequate relief or require additional surgery.

Need for revision surgery is a real possibility, particularly for patients who have total joint replacement. The prosthetic components have finite lifespans and may loosen, wear, or fail over time, necessitating revision or replacement.

Cross-network link note: While TMJ disorders can sometimes coexist with other chronic pain conditions like tinnitus or sciatica, treating these as interconnected systemic conditions requires careful interdisciplinary coordination. If you experience nerve pain radiating to other areas of your body, sciaticaspot.com offers resources specifically addressing sciatic nerve pain causes and treatments that may be relevant for some patients with widespread musculoskeletal symptoms.

Non-Surgical Alternatives to TMJ Surgery

Before accepting surgery as the only option, it is worth exploring — thoroughly and for an adequate duration — the full range of conservative treatments available. Many patients achieve significant improvement without ever reaching the surgical stage.

Custom Oral Appliances (Splints and Night Guards)

A custom-fitted oral appliance is one of the most well-researched and effective non-surgical interventions for TMD. There are several types:

  • Stabilization splints cover all the teeth and are designed to reduce clenching, stabilize the bite, and relax the jaw muscles. They are typically worn at night but can also be worn during the day.
  • Anterior positioning splints are designed to hold the jaw in a slightly forward position, which can help reposition a displaced disc in some patients.
  • NTI-tss devices are small, non-FDA-approved appliances that fit only on the front teeth and are designed to reduce clenching intensity by limiting posterior tooth contact. Devices like the NTI-tss Dental Device should only be used under the guidance of a dentist experienced in TMD treatment.

These appliances must be custom-fitted by a dentist experienced in TMD treatment. Over-the-counter "boil and bite" mouthguards are not appropriate substitutes and can sometimes worsen symptoms if they alter the bite negatively.

Physical Therapy

Physical therapy for TMD is a well-established treatment that focuses on improving jaw mobility, strengthening supporting muscles, and correcting posture and movement patterns that contribute to joint stress.

A physical therapist specializing in craniomandibular disorders may use techniques including:

  • Manual therapy (hands-on joint mobilization and soft tissue work)
  • Targeted jaw exercises to improve range of motion and strength
  • Postural training for the head, neck, and shoulder girdle
  • Trigger point release
  • Neuromuscular re-education

Research consistently supports physical therapy as an effective component of TMD management, with studies showing meaningful improvements in pain and jaw function when combined with other treatments.

Medications

Several classes of medication can help manage TMJ symptoms:

  • NSAIDs (ibuprofen, naproxen): Reduce joint inflammation and relieve pain. Useful for acute flares.
  • Muscle relaxants (cyclobenzaprine, methocarbamol): Help reduce muscle spasms and nighttime clenching.
  • Tricyclic antidepressants (amitriptyline, nortriptyline): Used in low doses for chronic pain management and to reduce nighttime grinding.
  • Anti-anxiety medications (clonazepam): In very low doses, can help reduce muscle activity. Used short-term due to dependence risk.
  • Gabapentin or pregabalin: For neuropathic pain components that may accompany TMJ disorders.

Corticosteroid and Hyaluronic Acid Injections

Corticosteroid injections into the joint space can reduce inflammation and provide pain relief for patients who do not respond adequately to oral medications. The effects are typically temporary (weeks to months), but they can break a pain cycle and allow other treatments to be more effective.

Hyaluronic acid injections are used in some countries as a viscosupplementation approach — similar to its use in knee osteoarthritis — to improve joint lubrication. Evidence is mixed, with some studies showing benefit and others finding no advantage over placebo.

Botox Injections for TMJ

OnabotulinumtoxinA (Botox) injections into the masseter, temporalis, and pterygoid muscles have become an increasingly popular treatment for TMD-related muscle pain and clenching. Botox temporarily weakens these muscles, reducing the force of clenching and the associated pain.

Studies have shown Botox injections can reduce muscle-related TMJ pain, though the effects are temporary (typically 3-4 months per treatment cycle) and the treatment is not suitable for everyone. It is also not FDA-approved specifically for TMD, meaning it is used "off-label."

Dietary and Lifestyle Modifications

Dietary changes are foundational to TMD management. Chewing hard, crunchy, or chewy foods places significant load on the TMJs and can exacerbate symptoms. A soft diet — focusing on soups, smoothies, steamed vegetables, fish, eggs, and well-cooked grains — reduces joint stress and allows inflammation to settle.

Beyond diet, stress management is critical for many patients because stress often manifests as jaw clenching and teeth grinding (bruxism). Techniques such as mindfulness meditation, cognitive behavioral therapy (CBT), yoga, and regular exercise can help reduce the unconscious muscle activity that drives TMD symptoms.

How to Decide: Making an Informed Choice

The decision to pursue TMJ surgery should never be rushed. If your clinician has recommended surgery, here is a framework for making an informed decision:

Get a Second Opinion

If surgery is recommended, seeking a second opinion from another oral and maxillofacial surgeon — ideally one who specializes in TMJ disorders — is entirely reasonable and should not offend your referring clinician. Different surgeons may have different perspectives on the best approach, and a second opinion can provide clarity and confidence.

Understand the Specific Procedure

Ask your surgeon to clearly explain:

  • What, specifically, the surgery will address (the exact pathology)
  • What the expected outcome is — not just pain relief, but specific functional improvements
  • What the realistic success rate is for your specific diagnosis
  • What happens if the surgery does not provide adequate relief

Ask About the Team and Facility

Successful TMJ surgery is most likely when performed by an experienced surgical team at a facility equipped for craniomandibular surgery. Ask about the surgeon's volume of TMJ procedures, the team members who will be involved in your care, and the post-operative rehabilitation program that will be provided.

Consider Your Mental and Emotional Readiness

Major surgery requires not just physical but mental preparation. Assess whether you are in a place where you can commit to the rehabilitation process — physical therapy, dietary restrictions, follow-up appointments — because post-operative rehabilitation is often as important as the surgery itself in determining outcomes.

Explore Every Reasonable Conservative Option First

If you have not yet tried a structured, comprehensive conservative program — including custom splint therapy, dedicated physical therapy, and medical management — that should be your starting point. Rushing to surgery before exhausting conservative options increases the likelihood of unnecessary surgery.

Frequently Asked Questions

When is TMJ surgery actually necessary?

TMJ surgery is considered necessary when conservative treatments have failed to provide adequate relief after a reasonable trial period (typically 6 months or more), and when diagnostic imaging confirms a structural problem within the joint that cannot be corrected through non-surgical means. Common indications include advanced internal derangement, ankylosis, severe degenerative arthritis, condylar resorption, and traumatic joint damage.

What are the different types of TMJ surgery?

The main categories, from least to most invasive, are arthrocentesis (joint irrigation with needles), arthroscopy (minimally invasive with a camera), arthroplasty (open joint surgery), condylectomy (removal of the condyle head), and total joint replacement (prosthetic joint). The procedure recommended depends on the severity and nature of the underlying joint pathology.

How long is recovery after TMJ surgery?

Recovery varies significantly by procedure type. Arthrocentesis requires 1-2 weeks of recovery. Arthroscopy requires 2-4 weeks for initial recovery. Open joint surgery requires 4-8 weeks for initial recovery, with full rehabilitation taking 3-6 months. Total joint replacement requires 6-12 months for full recovery.

What are the risks of TMJ surgery?

Risks include nerve damage (causing facial numbness or weakness), infection, bleeding, altered hearing or tinnitus, scarring, bite changes, and failure to relieve symptoms. The risk of permanent nerve injury is low but not zero, particularly with open joint procedures. Some patients also require revision surgery over time.

What alternatives exist to TMJ surgery?

Non-surgical alternatives include custom-fitted oral splints or night guards, physical therapy with jaw-specific exercises, medications (NSAIDs, muscle relaxants, anti-anxiety drugs), corticosteroid or hyaluronic acid injections, Botox injections for muscle hyperactivity, dietary modifications, and stress management techniques. A comprehensive conservative approach should be exhausted before surgery is considered.
