Endoscopic ear surgery (EES) is engaged nearly in all otology procedures in this era. The widespread application is faced by raised drawbacks that EES can induce thermal injury to the inner ear structures.
This retrospective study investigates the effect of endoscopic tympanoplasty on the postoperative sensorineural element of hearing and other inner ear functions. Cases of endoscopic tympanoplasty admitted to the tertiary referral center in the period of the study were included. Important audiologic data were collected including the preoperative and postoperative bone conduction threshold and air bone gap. The total endoscopic usage time during surgery was collected. Appropriate statistical testing was performed using SPSS 20.
The study included 51 patients who had endoscopic tympanoplasty. The mean age was (33.65 ± 10.840) years. The study showed no statistically significant difference between the preoperative and postoperative bone conduction threshold. In addition, Pearson correlation test showed no statistical association between the total endoscopic usage time and the postoperative bone conduction threshold. No significant vertigo nor facial nerve affection were observed in the postoperative period.
Endoscopic tympanoplasty as an example of EES does not affect the inner ear structures, clinically described as it does not affect the postoperative sensorineural hearing, facial nerve function nor the balance.
在这个时代，内镜耳科手术（EES）几乎应用于所有耳科手术。但其广泛应用面临着EES可对内耳结构造成热损伤等缺点。
本回顾性研究调查了内镜鼓膜成形术对术后感音神经性听力及其他内耳功能的影响。纳入了研究期间在三级转诊中心接受内镜鼓膜成形术的病例。收集了重要的听力学数据，包括术前和术后的骨导阈值及气骨导差。记录了手术期间内镜的总使用时间。使用SPSS 20进行了适当的统计检验。
该研究纳入了51例行内镜鼓膜成形术的患者。平均年龄为（33.65±10.840）岁。研究表明，术前和术后骨导阈值之间无统计学显著差异。此外，Pearson相关性检验显示内镜总使用时间与术后骨导阈值之间无统计学关联。术后未观察到明显的眩晕或面神经损伤。
作为EES的一个例子，内镜鼓膜成形术不影响内耳结构，临床表明其不影响术后感音神经性听力、面神经功能及平衡。
