To analyze the relationship between indwelling time after tube insertion and recurrence after tube removal or extrusion in children with secretory otitis media(SOM). Medical history and clinical data obtained by follow-up were analyzed in 465 pediatric patients with SOM who underwent tube insertion. ①331 of 465 children were followed up, including 220 males(66.47%), 111 females(33.53%), totally 576 ears in which SOM recurred in 177 ears after tube removal or extrusion with the recurrence rate of 30.73%. The average age was (4.69±2.18) years old in children who underwent tube insertion, gathering at age of 3 to 6 years. The average indwelling time was（9.96±3.72）months for all ears, while(8.59±3.49) months in recurrent ears, and(10.57±3.65) months in healing ears. The recurrence rate was 46.09% in ears in which indwelling time less than 6 months. The prevalence of allergic rhinitis in children with recurrent SOM after tube removal or extrusion was 59.62%, which was higher than the overall prevalence rate of 38.67%. ②Of 177 ears, a second time of the tube insertion was performed in 79 ears (44.63%). The average of the initial indwelling time was(7.50±3.40) months in children with recurrent SOM. The prevalence rate of allergic rhinitis in children who underwent a second time of the tube insertion was 68.09%, which was higher than rate of 29.07% in children cured. SOM was inclined to recur in 3-6 year old children. The shorter indwelling time and with allergic rhinitis in children, the higher recurrence rate after tube removal or extrusion. The recurrence rate was significantly lower when indwelling time was more than 13 months.
分析分泌性中耳炎（SOM）患儿置管后留置时间与拔管或脱管后复发之间的关系。对465例行置管术的SOM患儿的病史及随访获得的临床资料进行分析。①465例患儿中331例获得随访，其中男220例（66.47%），女111例（33.53%），共576耳，拔管或脱管后SOM复发177耳，复发率为30.73%。置管患儿平均年龄为（4.69±2.18）岁，以3～6岁居多。所有耳平均留置时间为（9.96±3.72）个月，复发耳为（8.59±3.49）个月，治愈耳为（10.57±3.65）个月。留置时间小于6个月的耳复发率为46.09%。拔管或脱管后SOM复发患儿变应性鼻炎患病率为59.62%，高于总体患病率38.67%。②177耳中，79耳（44.63%）再次置管。SOM复发患儿初次平均留置时间为（7.50±3.40）个月。再次置管患儿变应性鼻炎患病率为68.09%，高于治愈患儿的29.07%。SOM在3～6岁患儿中易复发。患儿留置时间短且伴有变应性鼻炎，拔管或脱管后复发率更高。留置时间超过13个月时复发率显著降低。
