title: Surgical drainage of a submandibular air sac in an orangutan.
abstract: Continuous enlargement of a submandibular air sac was observed in a 7-year-old female orangutan. The animal was treated with tetracycline orally prior to administering phencyclidine and establishing surgical drainage. The incision into the air sac remained patent for 5 days and the cutaneous wound healed 2 weeks later.
