Temporomandibular ankylosis, even though considered to be of a relatively rare emergence, can be encountered in day-to-day clinical practice. Most cases follow a typical, if not identical anamnesis pattern. The background of mechanical difficulties manifestation is associated with some trauma. The animals usually suffer a severe blow to the head, leading to a gradual development of the defect, which unfortunately most owners are not aware of, or claim not to be. This case report describes a typical incidence of post traumatic ankylosis of the temporomandibular joint (TMJ). The patient suffered a blow to the head at the age of 4 months, the clinical aftermath of which was a gradual difficulty in opening the mouth. A CT examination revealed the extent of damage in the region of the zygomatic arch, affecting also the corresponding TMJ. For this particular case, a surgical intervention was the only course of treatment, meaning the resection of arcus zygomaticus and the TMJ. The procedure was scheduled to be performed 14 days post the CT examination. Due to the fact that the changes were located only on the lateral surface of the TMJ, the plan was to resect and remove the affected area only, with the medial part of the TMJ left intact and in position. The joint capsule was then sutured. This approach proved to be very beneficial and effective in the outcome of the surgery and in aiding in the overall comfort of the patient.
