The study assessed otoscopic abnormalities, hearing status, and radiological changes in the ear opposite to the one affected by chronic otitis media in 300 patients.
More than 30% of patients had some abnormality in the contralateral ear, with different rates of abnormalities observed in types of chronic otitis media (Mucosal and Squamosal).
Surprisingly, 77% of patients still had normal hearing in the contralateral ear, showing that chronic otitis media can affect both ears, emphasizing the need for thorough evaluations.
