ICD-10: M26.61

The ICD-10 code M26.61 refers to "Adhesions and ankylosis of the temporomandibular joint (TMJ)," which encompasses a range of clinical presentations, signs, symptoms, and patient characteristics associated with this condition. Understanding these aspects is crucial for accurate diagnosis and effective management.

Clinical Presentation

Adhesions and ankylosis of the TMJ can manifest in various ways, often leading to significant functional impairment. Clinically, patients may present with:

• Limited Jaw Movement: Patients typically exhibit restricted range of motion in the jaw, making it difficult to open the mouth fully (trismus) or perform normal chewing activities.
• Pain: Discomfort or pain in the jaw area is common, which may be exacerbated by movement or pressure on the joint.
• Clicking or Popping Sounds: Some patients may report audible sounds during jaw movement, although this is more characteristic of other TMJ disorders rather than ankylosis specifically.

Signs and Symptoms

The signs and symptoms associated with M26.61 can be categorized as follows:

1. Physical Signs

• Decreased Mouth Opening: Measurement of the interincisal distance (the distance between the upper and lower incisors) may reveal a significant reduction, often less than 20 mm in severe cases.
• Facial Asymmetry: In some cases, patients may exhibit asymmetry in the facial structure due to altered jaw positioning.
• Tenderness on Palpation: The TMJ area may be tender to touch, indicating inflammation or irritation.

2. Symptoms

• Jaw Pain: Patients often describe a dull ache or sharp pain localized around the TMJ, which may radiate to the ear or neck.
• Headaches: Tension-type headaches or migraines can occur secondary to TMJ dysfunction.
• Difficulty Chewing: Patients may experience challenges with mastication due to pain or limited movement.
• Ear Symptoms: Some individuals report ear fullness, tinnitus, or even vertigo, which can be related to TMJ dysfunction.

Patient Characteristics

Certain demographic and clinical characteristics may be associated with patients diagnosed with M26.61:

• Age: Adhesions and ankylosis of the TMJ can occur at any age but are more commonly seen in young adults and middle-aged individuals.
• Gender: There is a slight female predominance in TMJ disorders, including ankylosis, possibly due to hormonal factors or differences in pain perception.
• History of Trauma: Patients with a history of facial trauma, surgery, or previous TMJ disorders are at higher risk for developing adhesions and ankylosis.
