Fungal otitis externa and tympanic membrane perforation

Abstract

Introduction

Otomycosis is a fungus-causing superficial infection of the external auditory canal that is common in otolaryngology practice. Though it is a worldwide infection, but is more prevalent in warm and humid regions. There has been rise in the occurrence of otomycosis in the last few years because of the extensive usage of antibiotic eardrops. Other influencing reasons for the occurrence of otomycosis is swimming, an immunocompromised host (e.g.: DM, AIDs) pregnancy, post-canal wall down mastoidectomy, tympanic membrane perforation, hearing aids and self-inflicted injuries.

Methods

Approval from the institutional ethics committee and penned informed agreement from all patients involved in the examination were obtained. 40 patients were included in the study, starting from 1stAugust to 30th September 2021, which emphasized on otomycosis infection with central tympanic membrane perforation. Physical findings such as whitish ear discharge and the presence of hyphae in the EAC, the ear drum, the middle ear mucosa were used to diagnose otomycosis.

Result

20 patients of patched group and 20 patients of non-patched group did not visit for follow up. Data here is for patients who followed-up for 3 weeks. Any significant observation regarding statistical variation in the age, size of perforation, mycological analysis and pure tone audiometry among the two groups were not seen.

Conclusion

To conclude, we state that treatment with clotrimazole solution in patched group is safe in managing otomycosis with tympanic membrane perforation. Otomycosis is a fungus causing surface infection of the external auditory canal that otolaryngologists routinely diagnose by medical examination. In acute otomycosis, overgrowth of the fungus in the external auditory canal is due to increased humidity.
