Black fungus due to covid-19: audiological assessment of middle ear functioning

Abstract

Background and Aim: A rare fungal infection, mucormycosis, has become more common in patients recovering from COVID in its second wave in India. The proximity and easy access to the middle ear through the Eustachian tube from paranasal sinuses alarms the need for early detec­tion of middle ear involvement. Hence, the study was carried out to determine the influence of mucormycosis on Immittance and otoacoustic emissions. Methods: eleven rhino orbital mucormycosis patients aged 40-60 years participated in the study. Middle ear evaluation was carried out with the help of Immittance and otoacoustic emissi­ons. Results: It was found that 4/11 (36.36%) parti­cipants had abnormal Immittance and absent oto­acoustic emissions, indicating middle ear dys­function. 3/4 participants had middle ear dys­function in the ear ipsilateral to the side of the infection. Conclusion: The study results reveal a rare cha­nce of middle ear involvement in mucormycosis patients, which calls for the crucial role of the audiologist in the early detection of middle ear dysfunction.
