title: Computed tomography and partial coronoidectomy for open-mouth jaw locking in two cats.
abstract: Open-mouth jaw locking in the cat has traditionally been minimally evaluated with diagnostic imaging. Multiple methods have been described for surgical management of this problem. This report describes the use of computed tomography to diagnose open-mouth jaw locking in 2 cats secondary to ventrolateral displacement of the coronoid process in relation to the zygomatic arch. In these 2 cases, a previously unreported surgical approach whereby the coronoid was not reduced before partial coronoidectomy was used with successful outcomes.
