The microflap technique is a standard procedure for the treatment of vocal fold polyps. Angiolytic laser surgery carried out under topical anesthesia is an alternative method for vocal polyp removal. However, it is not clear whether angiolytic laser surgery has the same effects on vocal outcomes as the microflap technique because of a lack of studies comparing both procedures. In the current study, vocal outcomes after both procedures were compared to clarify the effects of angiolytic laser surgery for vocal polyp removal.
Vocal outcomes were reviewed for patients who underwent angiolytic laser surgery (n=20, laser group) or microflap surgery (n=34, microflap group) for vocal polyp removal. The data analyzed included patient and lesion characteristics, number of surgeries required for complete resolution, and aerodynamic and acoustic examinations before and after surgery.
In the laser surgery group, complete resolution of the lesion was achieved with a single procedure in 17 cases (85%) and with two procedures in 3 cases (15%). Postoperative aerodynamic and acoustic parameters demonstrated significant improvement compared to preoperative parameters in both the laser surgery group and the microflap surgery group. There were no significant differences in any postoperative aerodynamic and acoustic parameters between the two groups.
The current retrospective study demonstrated that angiolytic laser surgery achieved complete resolution of vocal polyps within two procedures. Postoperative effects on aerodynamic and acoustic functions were similar to those after microflap surgery.
微型皮瓣技术是治疗声带息肉的标准手术方法。局部麻醉下进行的血管消融激光手术是去除声带息肉的另一种方法。然而，由于缺乏对这两种手术进行比较的研究，尚不清楚血管消融激光手术对嗓音结果的影响是否与微型皮瓣技术相同。在本研究中，对两种手术后的嗓音结果进行比较，以阐明血管消融激光手术去除声带息肉的效果。
回顾接受血管消融激光手术（n = 20，激光组）或微型皮瓣手术（n = 34，微型皮瓣组）去除声带息肉患者的嗓音结果。分析的数据包括患者和病变特征、完全消除病变所需的手术次数以及手术前后的空气动力学和声学检查。
在激光手术组中，17例（85%）患者通过单次手术实现病变完全消除，3例（15%）患者通过两次手术实现病变完全消除。激光手术组和微型皮瓣手术组术后的空气动力学和声学参数与术前参数相比均有显著改善。两组术后的任何空气动力学和声学参数均无显著差异。
当前的回顾性研究表明，血管消融激光手术在两次手术内可实现声带息肉的完全消除。术后对空气动力学和声学功能的影响与微型皮瓣手术后相似。
