title: [Two cases of laryngeal sac suppuration in orangutans in the Münster Zoological Park (all weather zoo)].
abstract: It is reported on two cases of pyosis of the laryngeal pouch in two Orang-outangs. In one case the disorder led to the death of the animal within three months, while the other was treated surgically and the pus drained. The discussion is based on available literature. The masked feature of the disorder and its insidious progress is pointed out. The cause is attributed to hereditary disposition and faulty zoo-keeping.
