An adult female Chinese goose (Anser cygnoides) presented with a ventral displacement of the hyoid apparatus, associated with distension of the intermandibular sublingual space and of the gular skin, causing difficulties with prehension and deglutition of food and water. Physical examination revealed that the tongue was able to move normally and could be replaced into a normal anatomical position by external compression of the distended ventral intermandibular region. A mild hypoalbuminemia was the only remarkable finding of the biochemistry panel. Radiographs and computed tomography scan of the head and neck regions confirmed a normal hyoid apparatus. An extraoral surgical reconstruction of the distended intermandibular skin was performed: the excess skin was incised and resected and the margins of the incision were sutured with appropriate tissue tension to obtain a good apposition and prevent ventral displacement of the hyoid apparatus. Postoperative complication included airway obstruction by a large amount of respiratory secretions, which were successfully aspirated from the trachea. A supportive elastic bandage was placed at the level of the beak commissure during the following 24 hours in order to reduce downward pressure on the suture line and minimize the risk of dehiscence of the suture. The goose resumed eating within 4 hours following the surgery and oxygen supplementation was discontinued after 24 hours. Respiration was assessed as normal and the tongue remained permanently in normal position. The lingual entrapment did not recur during the following 18 months.
