VetCAT imaging resolves intermittent jaw locking issue in one visit

Xoran’s VetCAT 3D CT scans provide same day solutions

A Rudy, a 2-year-old male Basset Hound, presented with a history of intermittent jaw problems. Rudy’s jaw would lock open when eating or vocalizing. VetCAT’s 3D CT imaging helped Dr. Colmery identify and repair Rudy’s issue in a single office visit.

VetCAT imaging shows the extent of bone loss and nasal changes caused by the oronasal fistula.

Dr. Colmery palpated Rudy’s jaw while he was under anesthesia and was able to reproduce the jaw locking.  A scan was taken with the mouth closed, and a second scan with the jaw locked open.


Dr. Colmery evaluated the 3D reconstruction and was able to quickly identify the problem: Rudy’s coronoid process was getting caught his zygomatic arch. Dr. Colmery performed a short surgical procedure resecting the tip of the coronoid process and Rudy went home the same day with a complete resolution of his symptoms.
