摘要:
To analyze anatomic variations of the temporal bone in congenital aural atresia (CAA) and their correlation with the Jahrsdoerfer score, in order to guide clinical selection of surgical treatment methods.We retrospectively studied 53 patients (72 ears) with unilateral or bilateral CAA, including 34 ears with normal hearing as controls. Audiological and imaging data were collected and analyzed. We evaluated the Jahrsdoerfer score and anatomical variations, including tegmen mastoideum position, anterior sigmoid sinus displacement, and elevated jugular bulb.The average air conduction hearing threshold (PTA4) ranged from 0.5 to 4 kHz was 65.48 ± 8.19 dBHL, with an average Jahrsdoerfer score of 4.93 ± 2.78. In CAA group, there was a higher prevalence and severity of anterior sigmoid sinus and low position of the tegmen mastoideum (P < 0.01). However, there was no significant difference in incidence rates among groups with high jugular bulb (P > 0.05). Anterior sigmoid sinus and high jugular bulb showed no correlation with the Jahrsdoerfer score, while the low position of the tegmen mastoideum had a weak correlation. The Jahrsdoerfer score did not adequately predict temporal bone anatomical abnormalities in CAA patients.CAA exhibit a higher incidence and greater severity of temporal bone anatomical abnormalities compared to the control group, and the Jahrsdoerfer score inadequately assesses these abnormalities. Anomalies like low position of the tegmen mastoideum, anterior sigmoid sinus, and high jugular bulb should also be considered as independent factors influencing surgical decisions for atresiaplasty.Copyright © 2024.
