Analysis on outcomes of facial paralysis complicated by middle ear cholesteatoma

Abstract

Background: The prognostic factors of facial paralysis complicated by middle ear cholesteatoma (MEC) are largely unknown due to limited reports and smaller sample size.

Objectives: This study aimed to analyze prognostic factors of postoperative outcomes of facial paralysis complicated by MEC.

Material and methods: Clinical data of 48 patients (48 ears) with facial paralysis complicated by MEC were retrospectively reviewed and analyzed. The outcomes of facial paralysis were compared between different groups.

Results: All the eight cases (100%) with intact fallopian canal had complete recovery of facial paralysis after surgery, while only 52.5% cases (21/40 cases) with fallopian canal damage achieved good recovery, with significant difference (p < .05). For subgroup analysis of the 40 cases with damaged fallopian canal, the good recovery rate of facial paralysis in shorter duration group (≤2 months) was higher compared to longer duration group (>2 months) (81.0% versus 21.1%; p < .05). Moreover, the good recovery rate of facial paralysis in moderate facial paralysis group (grade II–IV) was higher compared to severe facial paralysis group (grade V–VI) (82.4% versus 30.4%; p < .05).

Conclusions and significance: The outcomes of facial paralysis complicated by MEC were associated with fallopian canal integrity, duration and severity of facial paralysis.

背景：由于有限的报道和较小的样本量, 中耳胆脂瘤（MEC）并发面神经麻痹的预后因素在很大程度上是未知的。

目的：本研究旨在分析MEC并发面神经麻痹术后的预后因素。

材料与方法：回顾性分析48例（48个耳）MEC并发面瘫患者的临床资料。比较不同组之间的面瘫状态。

结果：所有8例（100％）面神经管完整的患者, 术后面瘫完全恢复；仅有52.5％（21/40例）面神经管损伤的患者恢复良好, 差异有显着性（p <0.05） ）。对于40例面神经管损伤患者的分析, 较短持续时间组（≤2个月）的面瘫恢复率高于较长持续时间组（> 2个月）（81.0％对21.1％; p <0.05）。此外, 中度面神经麻痹组（II-IV级）面瘫的良好恢复率高于严重面神经麻痹组（V-VI级）（82.4％对30.4％; p <0.05）。

结论和意义：MEC并发面神经麻痹的结果与面神经管完整性以及面瘫持续时间和严重程度有关
