Plain-English summary
A 3-year-old male horse was brought in because he had swelling on the left side of his jaw and was having trouble eating and drinking. Initial X-rays didn't show any problems, but a CT scan revealed that he had a fracture in a bone called the basihyoid and some damage to a muscle in his jaw. An ultrasound was done to confirm the fracture. The horse was treated conservatively, meaning he didn't need surgery, and after resting for four months, he was able to return to training without any issues.
Abstract
A 3-year-old gelding was presented for further evaluation and treatment of a swelling over the left mandible and inability to eat and drink. Radiographs of the mandible were unremarkable. Computed tomography (CT) of the head demonstrated a fracture of the basihyoid bone and partial avulsion of the medial pterygoid muscle. Ultrasound examination was performed to establish a baseline and confirmed the fracture. The gelding was managed conservatively, recovered uneventfully, and was able to return to training after 4 months of rest. Key clinical message: Computed tomography and ultrasonography in the horse provided information about injury to the basihyoid bone and insertion of the medial pterygoid muscle.
