目的:了解河南省儿童先天性耳聋颞骨畸形的发生率及特点,为临床提供必要的依据。方法:225例听力障碍的婴儿及先天性耳聋的儿童人工耳蜗植入前行颞骨HRCT筛查常规行横断面薄层扫描和多平面重组。结果:CT共检出颞骨畸形79例(104耳),包括外耳畸形25例(30耳)、中耳畸形16例(20耳)、内耳畸形54例(74耳),其中16例为合并畸形;单纯鼓室积液30例(42耳);其余116例颞骨无异常。35.1%患儿颞骨有畸形,51.6%患儿颞骨结构正常。结论:HRCT能很好显示儿童先天性耳聋的颞骨解剖异常,为临床治疗方案的正确制定提供重要的参考依据。
Objective: To understand the incidence and characteristics of congenital deafness of temporal bone deformities in children in Henan Province, providing the necessary basis for clinical practice. Methods: 225 cases of hearing impaired children and congenital deaf children cochlear implant before temporal bone HRCT screening routine cross-sectional TLC and multiplanar reorganization. Results: Totally 79 cases (104 ears) of temporal bone deformities were detected in CT, including 25 cases (30 ears) of external ear deformities, 16 cases (20 ears) of middle ear deformities, 54 cases (74 ears) of internal ear deformities, and 16 of them were complicated deformities ; Simple tympanic fluid in 30 cases (42 ears); the remaining 116 cases without temporal bone anomalies. 35.1% of the children had deformities in the temporal bone and 51.6% of the children had normal temporal structures. Conclusion: HRCT can well display temporal anatomy of congenital deafness in children and provide an important reference for the correct formulation of clinical treatment.
