INTRODUCTION
Chronic otitis media with cholesteatoma is a locally destructive middle ear infection with bone erosive properties which can lead to fistula if erodes labyrinth.
MATERIALS AND METHODS
A prospective observational study was conducted at tertiary health care centre with a total of 12 patients who presented with complaints of otorrhoea, hearing loss and vertigo. Such patients were evaluated clinic audiologically and radiologically as a pre op assessment. Post-surgery audiological assessment was done.
RESULTS
Hearing preservation was seen in 91.7% patients and none of the patients had iatrogenic sensorineural hearing loss.
CONCLUSION
Complete removal of the cholesteatoma is beneficial and does not lead to any iatrogenic SNHL when performed meticulously. A newer way of diagnosing membranous labyrinthine breach utilizing Magnetic Resonance Imaging T2 Diffusion Weighted (MRI- T2 DW) sequence can be implemented.
引言
胆脂瘤型慢性中耳炎是一种具有骨质侵蚀特性的局部破坏性中耳感染，如果侵蚀迷路可导致瘘管形成。
材料与方法
在三级医疗保健中心进行了一项前瞻性观察研究，共有12例出现耳漏、听力损失和眩晕症状的患者。在术前评估中，对这些患者进行了临床听力学和放射学评估。术后进行了听力学评估。
结果
91.7%的患者听力得到保留，且无一例患者发生医源性感音神经性听力损失。
结论
精心操作时，彻底清除胆脂瘤是有益的，且不会导致任何医源性感音神经性听力损失。可以采用一种利用磁共振成像T2扩散加权（MRI-T2 DW）序列诊断膜迷路破裂的新方法。
