The outcomes of endoscopic myringoplasty: packing with gelatin sponge versus packing with nothing

Abstract

Background: Packing with gelatin sponge has long been widely used in myringoplasty. However, there is no research on packing with nothing.

Aims/objectives: To analyse the differences between packing with gelatin sponge and packing with nothing.

Material and methods: Patients with tympanic membrane perforation were randomly divided into a packing with gelatin sponge group and a packing with nothing group. Differences between the groups were compared.

Results: The operation time of group A (34.00 ± 1.05 min) was significantly shorter than that of group B (42.20 ± 1.40 min; p < .00); 1 patient (2.86%) in group A and 35 patients (100%) in group B had a dry ear time of longer than 1 week (p < .001). Ten patients (28.57%) in group A and 24 patients (68.57%) in group B had aural fullness after the operation (p < .001). The air-bone gap (ABG) in group A was smaller than that in group B at 1 week, 1 month, 2 months and 3 months after the operation (p < .05).

Conclusion and significance: Group A achieved the same good results, but it had a short operation time, an early dry ear time, a low incidence of aural fullness and early recovery of hearing.

Chinese abstract

背景：在鼓膜成形术中, 明胶海绵填塞的应用由来已久。然而, 目前还没有关于不用填塞的研究。

目的：分析填塞以明胶海绵与不用填塞的区别。

材料与方法：将鼓膜穿孔患者随机分为明胶海绵填塞组和无填塞组。比较两组间的差异。

结果：A组的手术时间（34.00±1.05分钟）明显短于B组（42.20±1.40分钟）, p<0.00；A组1例（2.86%）和B组35例（100%）的干耳时间大于1周（p<0.001）。A组10例（28.57%）和B组24例（68.57%）术后出现耳胀（p<0.001）。术后1周、1个月、2个月、3个月, A组的气骨间隙均小于B组（p＜0.05）。

结论及意义：A组和B组都取得了较好的疗效, 但A组手术时间短, 干耳时间早, 耳胀发生率低, 听力恢复早。
