Myiasis of the maxillary sinus caused by cochliomyia macellaria larvae and review of literature.

A case of myiasis of the maxillary sinus caused by Cochliomyia macellaria was reported in a seventy-four-year old Thai woman. She had a history of enucleation of her left eye because of endophthalmitis due to chronic maxillary sinusitis. She presented with painful facial swelling and purulent nasal discharge and was admitted. The patient was treated successfully with parenteral antibiotics to control associated bacterial infection, and Caldwell-Luc operation with removal of the maggots and antrostomy. Chronic sinusitis was considered to be a contributing factor to the myiasis of the paranasal sinus in the patient. Previously reported cases in Thailand are reviewed.
