目的：本研究的目的是评估传统技术（CT）和磷酸钛氧钾激光（KTP）激光辅助镫骨手术（不涉及操纵足板）之间的听力结果和并发症的差异。研究方法：对98耳因耳硬化症引起的传导性或混合性耳聋患者，采用CT或KTP激光辅助手法进行手术治疗。纯音测听的结果，术后前庭症状的持续时间，以及存在的损害脚板进行了回顾性审查。结果：两组听力改善程度及前庭症状持续时间无显著差异。与CT组相比，KTP组的足板损伤频率明显较低。CT组中有1例发生了严重的感音神经性听力损失，而KTP组中未检测到明显的感音神经性听力损失。结论：根据我们目前的研究结果，即使KTP激光不用于打开脚板，KTP激光辅助手术在对脚板的损伤方面也比CT更安全。然而，这两种技术在听力改善和前庭症状方面表现出相似的结果。
Objective: The purpose of the current study was to evaluate the differences in hearing results and complications between the conventional technique (CT) and potassium titanyl phosphate laser (KTP) laser-assisted stapes surgery that does not involve the manipulation of the foot plate. Methods: Ninety-eight ears with conductive or mixed hearing loss due to otosclerosis were operated on by using the CT or KTP laser-assisted manipulation. The results of pure-tone audiometry, the duration of postoperative vestibular symptoms, and the presence of damage to the foot plate were reviewed retrospectively. Results: The extent of hearing improvement and the duration of vestibular symptoms were not significantly different between the two groups. The damage to the foot plate was significantly less frequent in the KTP group compared to the CT group. Profound sensorineural hearing loss occurred in one case in the CT group, whereas no significant sensorineural hearing loss was detected in the KTP group. Conclusions: According to our present findings, KTP laser-assisted surgery was safer than CT in terms of the damage to the foot plate even when the KTP laser was not used for opening the foot plate. However, both techniques showed similar results in hearing improvement and vestibular symptoms.
