Abstract

Temporomandibular joint (TMJ) ankylosis is a rare disease impairing mandible movement and can either be intra-articular (true) or extra-articular (false). A cat presented with an inability to open its mouth, drooling, and facial asymmetry. Computed tomography (CT) confirmed an extracapsular abnormal TMJ fusion, and a surgical plan was devised based on the CT imaging. Post-surgery, the cat regained mouth mobility (indicating false ankylosis) and showed an improved prognosis. This case of CT-diagnosed and treated feline TMJ false ankylosis underscores the indispensable role of CT in diagnosing and devising surgical strategies for feline TMJ false ankylosis.
