Context and Aims: Since unilateral chronic suppurative otitis media (CSOM) does not look to be an isolated entity, but rather a series of constitutional events that affecting both ears, so this study aimed to evaluate the otoscopic, radiological, and audiological status of the contralateral ears (CLEs) in patients with unilateral CSOM. Patients and Methods: A prospective, observational study recruited 96 consecutive patients with unilateral CSOM with or without cholesteatoma, in whom their CLEs revealed an intact tympanic membrane (TM) were categorized as "Group 1" and "Group 2" respectively, they were evaluated with otomicroscopy, computed tomography (CT) scanning of temporal bones, pure tone audiometry and tympanometry. All above-mentioned observations were recorded and analyzed. Results: The incidence of otoscopic CLEs structural abnormalities was 47.91% in both groups; being 45.83% in "Group 1" mostly 25% of TM retraction, and 50% in "Group 2" mainly (20.84%) of thinning TM. Mastoid CT scan showed (35.41%) air cell abnormalities in both groups; being 37.5% in "Group 1" and 33.33% in "Group 2," while tympanic cavity mucosal thickening was 33.33% "in Group 1" and 25% in "Group 2." Conductive hearing loss was found (39.58%) in both groups; being 45.83% in "Group 1" and 33.33% in "Group 2," while C-curve tympanometry curve was 63.63% and 36.36% in both groups, respectively. Conclusions: The incidence of otoscopic structural abnormalities of CLEs was mainly in the form of TM retraction in squamous type and thinning TM in mucosal type; also, the radiological and audiological abnormalities of the CLEs were shown more event in squamous than in mucosal type of CSOM.
