Plain-English summary
A 13-month-old dog was brought to the vet because it couldn't close its mouth properly, a condition known as locked jaw. After a CT scan, the vet found a bone issue in the dog's skull that was causing pain and misalignment in the jaw joint. Attempts to fix the jaw without surgery didn't work, but a partial surgery to correct the bone problem successfully resolved the dog's symptoms. The dog is now able to close its mouth normally again.

Abstract
A 13-month-old dog was investigated for the complaint of open-mouth locked jaw. There were not any previous episodes of trauma witnessed. Computed tomographic evaluation revealed unilateral zygomatico-temporal synostosis and associated craniofacial asymmetry, with impingement of the mandibular coronoid process resulting in unilateral temporomandibular joint subluxation. Closed reduction of the subluxation was not maintained. Partial zygomatico-temporal suturectomy resulted in resolution of the clinical signs. To the author's knowledge, isolated zygomaticotemporal syno-stosis with associated temporomandibular subluxation has not been reported in the dog.
