Aural and Nasal Myiasis

Abstract

Myiasis is a parasitic infestation by fly larvae. It is usually associated with poor hygienic conditions. Most of the literature consists of individual case reports or short case series. In this study, we report eight cases of myiasis who present with aural or nasal symptoms. Material and Methods: It's a retrospective study included 8 patients with ear, nose and throat myiasis diagnosed over a 9-year period, from 2013 to 2022. Results: The study included 6 male and 2 female patients, aged from 9 to 84 years. Two patients were bedridden. There were 6 cases of aural myiasis and 2 of nasal myiasis. All of the patients with aural myiasis had a history of chronic otitis media. A patient with nasal myiasis had a nasogastric tube as a predisposing factor. In the other case of nasal myiasis, there was no comorbid disease, there was a history of ocular myiasis. For the treatment of myiasis infection, all maggots were cleaned one by one with a microscope or endoscope. No reinfection was observed in patients followed up for 1 month. Conclusion: Otorhinolaryngologic myiasis is very rare and mostly seen as an ear infection. Especially for aural myiasis, suppurative otitis can be a predisposing factor. Diagnosis is often easy. Myiasis should be kept as one of the possible diagnoses in patients with otitis media and in patients with long-term nasal tubes. Treatment of this parasitic infection is resection of maggots.
