The hyoid apparatus of the Chinese goose is composed of a single entoglossal bone, paired rostral basibranchial bones, an urohyal bone, paired ceratobranchial bones, and paired epibranchial bones.
Because a reducible luxation of the entoglosso-basibranchial joint or a nondisplaced fracture of a ceratobranchial bone (6) could not be ruled out, a computed tomography scan was recommended.
In the reported case of a goose with a fracture of a ceratobranchial bone, the clinical presentation was similar to this case but the bird was able to eat despite the fracture and the swelling was asymmetrical.
