Abstract: Background: Human myiasis can present as aural myiasis, nasal myiasis, ocular, urogenital etc. Aural myiasis can lead to perforation of tympanic membrane, hearing loss, haemorrhage and rarely the larva migrates into the meninges. Inflammatory reaction at the site of larva position may limit larval development due to mast cell activation and IgE production. Flies are generally attractive to odour of decaying necrotic tissue, which can arise from chronic otorrhea or sinusitis. Methods: The study was conducted at Dr. Ulhas Patil Medical College in the Department of Otorhinolaryngology from January 2020 to January 2022. On examination patients were irritable and blood stained ear discharge was noted in aural cases, while similar discharge from the nose in nasal cases. Results: Over the 2 years study period a total of 200 cases of myiasis were seen. The youngest child seen was 11 months and the oldest 70 years of age. Females (57.89%) were affected more commonly than males (41.48%). Most cases (96.8%) were from a rural background. Aural myiasis occurred from May to December. The peak incidence for both was seen from September to October. Conclusion: Myiasis is a rare and benign manifestation with zero Mortality rate. Meanwhile as it has been hypothesized in otorhinolaryngology that intracerebral myiasis can be caused by the transcanal migration and invasion of fly larvae, there was no association between aural myiasis and intracerebral pathology of any kind observed in the study. The overwhelming majority of cases can be successfully managed without the need for surgical intervention.
