Abstract

Infestation of tissue by fly larvae is termed myiasis, and it is unusual in humans. Nasal myiasis is common in low socioeconomic status individuals due to poor nasal hygiene. It commonly affects the skin and rarely the nasal and paranasal sinuses. Recently an 82-year-old female was admitted to the emergency department because of discharge of live maggots from the nasal cavity. She had been diagnosed with brain infarction and Alzheimer's disease several years previous. We successfully removed all the maggots from the patient's nasal cavity and sinuses via endoscopic surgery under local anesthesia. Subsequently, the patient's nasal problem resolved completely.
