Per-Lee 管是一种长期的中耳通气管,对咽鼓管阻塞或机能障碍、分泌性中耳炎的病人有一定的治疗价值,但效果并非都令人满意。本文对29例病人插入的37个 Per-Lee 管作4年以上的回顾性评价。其中儿童21例,29管;成人8例,8管。插入时间最长者48个月,最短12个月。儿童插入后的听觉效果令人失望:41.4%耳有轻微改善,其中仅有4耳(13.7%)达到正常10dB 以内,24.1%耳在暂时性改善后又 Per-Lee tube is a long-term middle ear ventilation tube, which has certain therapeutic value for patients with eustachian tube obstruction or dysfunction and secretory otitis media, but the results are not satisfactory. In this paper, we retrospectively evaluated 37 Per-Lee tubes inserted in 29 patients for more than 4 years. Among them 21 cases of children, 29 tubes; 8 cases of adult, 8 tubes. Insert the longest 48 months, the shortest 12 months. The hearing effect in children after insertion was disappointing: 41.4% of the ears had a slight improvement, of which only 4 ears (13.7%) reached within 10dB of normal, 24.1% of the ears were temporarily improved
