Intranasal myiasis: a rare complication of transnasal skull base surgery

Abstract

A 57-year-old woman with a history of atypical intracranial meningioma had undergone multiple craniotomies and endoscopic skull base procedures over several years. She presented most recently with nasal discharge consisting of intranasal larvae. Isolated organisms from the nasal cavity and maxillary sinus were identified as blow fly larvae (Calliphoridae family). The patient was treated with transnasal debridement and antibiotic therapy. The organisms were successfully eradicated and she is free from further signs of infection. Intranasal myiasis is an unusual complication of anterior skull base surgery.
