Temporomandibular joint ankylosis and salivary mucocele in a cat: case report

An approximately 1.5-year-old, not neutered mixed breed cat was referred for evaluation of inability to open its Mouth, and soft tissue swelling around the intermandibular region. Both signs were present since the cat was adopted, 1 year before presentation. The cause of the signs was not determined prior to referral. Based on the physical and radiographic examinations, left temporomandibular joint ankylosis and salivary mucocele were diagnosed. The lateral aspect of the condyloid process of the left mandible was removed and the salivary mucocele was treated by right mandibular and sublingual gland resection and drainage of the mucocele. After Surgery, the cat showed good functional use of the mandible without discomfort.
