ABSTRACT
OBJECTIVE@#Analyze the data of the patients with sensorineural hearing loss in China and study the classification and incidence of inner ear malformationsby the high-resolution computed tomography.@*METHOD@#The investigation took a retrospective review of CT findings relating to the 2,747 cases of outpatients. The inner ear malformations diagnosed by CT were classified according to the methods proposed by Sennaroglu.@*RESULT@#(1)843 cases of inner ear malformations were found in 2747 cases of patients with sensorineural hearing loss by CT examination. The incidence of inner ear malformation was 30.69%(843/2747). (2) The epidemiological information of 843 cases of inner ear malformation according to Sennaroglu's classification was as follows cochlea was 52. 31%(441/843), simple vestibular aqueduct was 40.33%(340/843), simple vestibular/ semicircular canal/internal auditory canal were 7. 35%(62/843) of the group. (3) 441 cases of cochlea malformation were consisted of these types of malformation Michel deformity was 1.13% (5/441), cochlear aplasia was 1. 81% (8/441), common cavity deformity was 3. 17% (14/441), incomplete partition type I was 8. 62% (38/441), cochlea hypoplasia was 9. 07% (40/441) and incomplete partition type II was 76. 19% (336/441) of the group.@*CONCLUSION@#The results suggested that 30. 69% cases of inner ear malformation can be found in patients with sensorineural hearing loss, which is more higher than reported by the high-resolution computed tomography. Sennaroglu's classification is instructively significant in investigating the status of inner ear malformations.
