[Nasal myiasis].

Thirty fly maggots were retrieved from the nasal cavity of a 23-year old man who had one week previously received treatment for a nasal fracture. The larvae were identified as Calliphora erythrocephala. These are not a common cause of myiasis as they normally breed on carrion. In myiasis it is important to establish whether the larvae are invasive or not. A brief description of nasal myiasis is given.
