The incidence rate of recurrence of otitis media with effusion (OME) in children after tympanostomy tube extrusion and the relationship between recurrence and tube retention time was investigated. Also relationship between recurrence rate and initial age of tube insertion was analysed.
A retrospective case series of patients who had tympanostomy tube insertion.
A total of 91 children (169 ears) were reviewed. Ears of children divided into three groups according to retention time of tympanostomy tubes. Group I: tympanostomy tube retention time less than 6 months. Group II: tympanostomy tube retention time 6 months to 12 months. Group III: tympanostomy tube retention time 12 months or more.
OME recurrence rate after tube extrusion was 20.7% in the study. The longer the tympanostomy tube retention time was the lower was the recurrence rate of OME. The comparison of the three groups indicated that recurrence rates were higher in group I (36.54%), than in group II (17.74%) and in group III (9.1%). There were statistically significant differences in recurrence rates between group I and group III, and between group I and II (p<0.05, p<0.05). However, the difference in recurrence rates between group II and group III was statistically not significant (p>0.05). In the preschool age group and school age group, the recurrence rates were 5.5% and 15.4%, respectively. There was no significant difference between these two groups (p>0.05). OME recurrence was observed in 9.9% of males and in 11% of females. There was no significant difference in recurrence rates between males and females (p>0.05).
After extrusion of tympanostomy tube, children should be followed-up regularly for recurrence of OME. The shorter the retention time of tympanostomy tubes was the higher was the recurrence rate. For the treatment of OME the ideal type of tubes should have the lowest complication and recurrence rates. Further studies are needed to ascertain the relationship between the incidence of OME and optimal tympanostomy tubes duration of tube stay in tympanic membrane. Therefore, new studies with larger series are necessary to investigate the correlation between the recurrence rates and different tympanostomy tubes after extrusion of tubes.
研究鼓膜置管取出后儿童分泌性中耳炎（OME）的复发率以及复发与置管保留时间的关系。同时分析复发率与初次置管年龄之间的关系。
对鼓膜置管患者进行回顾性病例系列研究。
共纳入91例儿童（169耳）。根据鼓膜置管的保留时间将患儿的耳朵分为三组。第一组：鼓膜置管保留时间少于6个月。第二组：鼓膜置管保留时间为6个月至12个月。第三组：鼓膜置管保留时间为12个月或更长时间。
本研究中置管取出后OME的复发率为20.7%。鼓膜置管保留时间越长，OME的复发率越低。三组比较表明，第一组的复发率（36.54%）高于第二组（17.74%）和第三组（9.1%）。第一组与第三组之间以及第一组与第二组之间的复发率存在统计学显著差异（p<0.05，p<0.05）。然而，第二组与第三组之间的复发率差异无统计学意义（p>0.05）。在学龄前组和学龄组中，复发率分别为5.5%和15.4%。这两组之间无显著差异（p>0.05）。男性OME复发率为9.9%，女性为11%。男性和女性的复发率无显著差异（p>0.05）。
鼓膜置管取出后，应对儿童进行OME复发的定期随访。鼓膜置管保留时间越短，复发率越高。对于OME的治疗，理想的置管类型应具有最低的并发症和复发率。需要进一步研究以确定OME发病率与鼓膜最佳置管时间之间的关系。因此，有必要进行更大样本量的新研究来探讨置管取出后不同鼓膜置管与复发率之间的相关性。
