Popis: Objectives:Evaluate the contralateral ear (CLE) audiometric findings in patients with middle ear cholesteatoma. (2) Correlate the audiometric thresholds to videotoscopic findings.Methods:Cross-sectional study. Videotoscopies and audiometries of 300 patients with cholesteatoma at a tertiary hospital were analyzed. The CLE videotoscopy, bone conduction, air conduction, and air-bone gap pure tone average (PTA) were analyzed.Results:The mean patient age was 32.35 ± 19.26 years, and 52.2% were female. The CLE was abnormal in 60.8% of cases: 5.6% had perforation, 39.9% had moderate or severe retraction, and 15.6% had cholesteatoma. The CLE bone conduction PTA was 16.75 ± 16.1 dB, the air conduction PTA was 47.1 ± 22.8 dB, and the air-bone gap PTA was 32.2 ± 18.7 dB. The CLE prevalence of severe and profound sensorineural hearing loss was 1.7%. Severe hearing impairment did not occur in patients with a normal CLE, whereas it did occur in 2.7% of patients with an abnormal CLE (P = .02). Bone conduction PTA was si...
