Name of the Procedure:

Arthrotomy, Temporomandibular Joint (TMJ)

• Common name(s): TMJ Arthrotomy
• Technical/Medical terms: Temporomandibular Joint Arthrotomy

Summary

Arthrotomy of the temporomandibular joint is a surgical procedure that involves making an incision into the TMJ to diagnose, treat, or repair issues within the joint. It’s often used to address severe TMJ disorders that don't improve with non-surgical treatments.

Purpose

• Medical condition or problem it addresses: Severe temporomandibular joint disorders, including arthritis, dislocations, structural anomalies, or growth abnormalities within the joint.
• Goals/expected outcomes: Relieve pain, restore normal function, improve joint movement, and address structural defects or diseases within the TMJ.

Indications

• Persistent pain or dysfunction despite conservative treatments.
• TMJ dislocations or structural anomalies.
• Diagnosed TMJ arthritis or growth abnormalities.
• Severe jaw locking or limited jaw movement.
• MRI or CT scan indicating internal joint pathology.

Preparation

• Fasting typically required 8 hours before the procedure.
• Adjustments to medications as advised by the healthcare provider.
• Pre-operative diagnostic tests may include X-rays, CT scans, or MRIs of the TMJ.
• Consultation with an anesthesiologist for anesthesia planning.

Procedure Description

1. Anesthesia: General anesthesia is administered to ensure the patient is completely unconscious and pain-free.
2. Incision: A small incision is made in front or behind the ear to access the TMJ.
3. Inspection and Treatment: The surgeon inspects the joint and may remove, repair, or reposition joint structures as necessary.
4. Closure: The incision is sutured, and a dressing is applied.
5. Post-surgical protocol: The joint area may be bandaged to minimize swelling and support recovery.

• Tools/Equipment: Surgical scalpels, retractors, sutures, and dressing materials.
• Anesthesia Details: General anesthesia is commonly used to ensure patient comfort and immobility during the procedure.

Duration

The procedure typically takes 1 to 2 hours, depending on the complexity of the case.

Setting

Arthrotomy of the TMJ is usually performed in a hospital operating room or an outpatient surgical center.

Personnel

• Oral and maxillofacial surgeon or otolaryngologist (ENT specialist)
• Surgical nurses
• Anesthesiologist
• Operating room technicians

Risks and Complications

• Common risks: Infection, bleeding, swelling, and pain.
• Rare risks: Nerve damage, joint stiffness, facial weakness, changes in bite or occlusion.
• Management of complications generally involves medications, physical therapy, and in some cases, additional surgical interventions.

Benefits

• Expected benefits include significant pain reduction, improved jaw function, and resolution of structural problems.
• Benefits might be realized soon after recovery, with continued improvement over several weeks to months.

Recovery

• Post-procedure care includes pain management, antibiotics, and perhaps anti-inflammatory medications.
• Patients are often advised to follow a soft food diet initially.
• Physical therapy may be recommended to restore normal jaw function.
• Recovery time can range from a few weeks to a few months, with follow-up appointments to monitor progress.

Alternatives

• Non-surgical treatments: Medications, physical therapy, dental splints, and lifestyle modifications.
• Other surgical options: Arthrocentesis, arthroscopy, or total joint replacement.
• Pros and cons: Non-surgical treatments carry fewer risks but may not be as effective for severe cases. Other surgical options have different indications and risk profiles.

Patient Experience

• During the procedure, the patient will be under general anesthesia and won’t feel anything.
• After the procedure, they may experience swelling, discomfort, and pain, usually manageable with prescribed medications.
• Pain management includes analgesics, and comfort measures involve cold compresses and a gradual return to normal activities.
