Resumo

Objective: To evaluate the findings of otosclerosis in the temporal bone CT compared with the results of the pre and post-surgical audiometry analysis. Method: 44 patients were included, with a total of 53 ears. The diagnosis of otosclerosis was made by audiometry in conjunction with CT and surgery findings. The post-surgical evaluation was performed with audiometry. SPSS Statistics 23.0 was used for the data processing. The involvement of the fissula ante fenestram (group 1) was considerate fenestral affectation. The diffuse or patched cochlear involvement (group 2) was considerate coclear or retrofenestral involvement. Audiometry was recorded as the pure tonal average of the frequencies 500, 1000, 2000 and 4000 Hz, and the bone-air gap, was obtained before and after surgery. P value <0.05 was considered statistically significant. Results: Of the 53 ears affected by otosclerosis, 16 ears (30%) had cochlear involvement and 37 (60%) fenestral involvement. The average diameter of the otosclerosis focus was 2.47 mm, with a standard deviation of 1.51 and the height of the oval window niche was 1.55 mm with a standard deviation of 0.35, without identifying statistically significant differences between the two groups. A significant relationship (Pearson's linear correlation, p <0.05) was identified between the diameter of the otosclerosis focus and the audiometric values measured in dB. Conclusion: The findings of our study show the usefulness of temporal bone CT in the evaluation of the extension of the otosclerosis focus, since a greater extension of the otosclerosis focus is associated with greater sensory hearing loss and with less hearing recovery after the surgical intervention.
