目的探讨颞部CT检查对听力筛查未通过的新生儿患者的作用。方法对2005年9月~2008年12月在我院五官科行听力筛查中2次及以上复筛“未通过”的新生儿患者798例,进行颞部CT检查,对CT图像进行分析和评价,并对其中35例中耳乳突炎患者复查CT检查。结果798例新生儿患者中,单侧外耳道闭锁12例,占1.5%,外耳道欠通畅18例,占2.3%,双侧外耳道闭锁伴中耳发育畸形2例,占0.2%,中耳乳突炎445例,占55.8%,中耳畸形5例,占0.6%,内耳畸形11例,占1.4%,单侧中耳及内耳发育畸形2例,占0.2%,CT扫描未见异常303例,占38.0%。35例中耳乳突炎患者复查CT检查,其中29例明显好转,6例改变不明显。结论听力筛查未通过的患者进行颞部CT扫描,对于听力障碍患者的早期诊断、早期干预、有效地减轻听力损失程度,促进语言发育等临床工作有着重要的指导作用。
Objective To investigate the effect of temporal CT examination on neonates with failed hearing screening. Methods From September 2005 to December 2008 in our hospital ENT hearing screening in the second and more re-screening “failed ” in 798 cases of neonatal patients, CT examination of the temporal CT images Analysis and evaluation, and in which 35 cases of otitis media in patients with CT review. Results Among the 798 newborn infants, unilateral external auditory canal atresia was found in 12 cases (1.5%), external auditory canal was unobserved in 18 cases (2.3%), bilateral external auditory canal obstruction was associated with middle ear malformation in 2 cases (0.2%), middle ear mastoiditis There were 445 cases (55.8%), 5 cases of middle ear deformities (0.6%), 11 cases of inner ear deformities (1.4%), 2 cases of unilateral middle ear and inner ear developmental malformations (0.2%), 303 cases of abnormal CT scan 38.0%. 35 cases of otitis media in patients with recurrent CT examination, of which 29 cases improved significantly, 6 cases did not change significantly. Conclusions CT scan of patients who did not pass the hearing screening was an important guide to early diagnosis, early intervention, effective hearing loss reduction and language development in patients with hearing impairment.
