Human nasal myiasis caused by oestrus ovis: two case reports and review of the literature

Oestrus ovis–induced nasal myiasis is generally self-limiting, mild, and extremely rare in humans. Nasal myiasis should be excluded in every patient who has nasal complaints and feels a foreign body moving in the nasal passage. Two patients were admitted to our clinic with the complaint of worms coming out of their noses. Physical examinations of the patients were normal. Endoscopic sinus sur-gery was performed in case 1 in which larvae were observed in paranasal computed tomography (CT). In case 2, nasal irrigation and monitoring were recommended owing to a normal CT scan. No additional complaints or recurrences were observed in either patient during the 3-month period. In this article, management of cases, removal of living worms, supportive treatment, and morphological features of worms are explained in light of the current literature.
