作者观察两耳插通气管小儿31例,年龄3～13岁,男17女14。每个小儿随机一耳插钛通气管,另耳插聚四氟乙烯通气管,均置于鼓膜前下象限。术后4、8、12和16个月依中耳感染史、耳镜检查和纯音测听评价功能。依耳显微镜检查和/或鼓室压测定判明通气管位置及是否开放。钛通气管内径1.25mm,内凸缘圆形直径2.75mm,聚四氟乙烯分别为1.0mm和2.25mm。结果:两种通气管感染率无明显差异,但伴有感染的钛通气管周围肉芽组织增生者5例中占4例,2个通气管阻塞;特氟隆通
The authors observed two ears inserted through the trachea in 31 children, aged 3 to 13 years old, male 17 female 14. Each pediatric random insertion of titanium ventilation tube ear, the other ear inserted PTFE ventilation, are placed in the anterior tympanic quadrant. 4,8,12 and 16 months after surgery according to the history of middle ear infections, otoscopy and pure tone audiometry evaluation. Erlen microscopic examination and / or tympanometry to determine the ventilation tube position and whether open. Titanium ventilation tube diameter 1.25mm, the inner flange diameter of 2.75mm, polytetrafluoroethylene 1.0mm and 2.25mm respectively. Results: There was no significant difference in infection rate between the two types of ventilation tubes. However, in 5 cases with concomitant infection of titanium ventilation tube, there were 4 cases with hyperplasia of the granulation tissue and 2 ventilation tubes obstructed. Teflon
