Case report demonstrates successful endoscopic removal of parasitic larvae in a 70-year-old woman, highlighting the need to evaluate the Eustachian tube in extensive nasal myiasis.
Nasal myiasis is a rare parasitic disease caused by infestation of the nasal cavity by fly larvae and may lead to serious complications if left untreated. Eustachian tube involvement is exceptionally uncommon. We describe a 70-year-old woman who presented with left-sided epistaxis and headache. Endoscopic examination revealed numerous larvae in the left nasal cavity, nasopharynx, and around the pharyngeal opening of the Eustachian tube. Imaging studies demonstrated chronic sinusitis without bony destruction. Endoscopic surgical removal of the larvae was performed under general anesthesia, resulting in complete symptom resolution and absence of residual infestation at the 2-week follow-up. This case highlights the importance of early recognition and prompt surgical management of nasal myiasis and emphasizes that the Eustachian tube should be carefully evaluated in patients with extensive infestation.
