Computed tomographic diagnosis: Traumatic lingual process fracture and surgical resection

Summary A 9-year-old mare was presented with abnormal behaviour and head-shaking when ridden. Pathology of the hyoid apparatus was suspected and computed tomographic (CT) examination of the head was suggested. Computed tomographic images revealed a fractured lingual process (LP) of the basihyoid bone. Surgical resection of the fractured LP was performed. The mare recovered uneventfully and symptoms improved 10 weeks post-operatively.
