支撑喉镜下810nm半导体激光治疗声带突肉芽肿

目的 探讨声带突肉芽肿的半导体激光治疗的方法.方法 声带突肉芽肿患者14例.半导体激光波长810nm,光纤直径0.6nm,输出功率0.5～30W,照射时间2～5 s,在支撑喉镜下对声带突肉芽肿以接触和非接触方式交替照射进行凝固、气化切除.结果 14例患者随访2～4年,一次性治疗后痊愈11例,二次治疗后痊愈2例.一次治愈率78.5%,总治愈率100%.声带功能恢复,无明显并发症.随访2～4年无复发.结论 支撑喉镜下半导体激光切除声带突肉芽肿,疗效显著、复发少,是传统喉镜手术后复发的有效补充治疗.

Treatment for Vocal Process Granuloma by 810 nm Semiconductor Laser Combined with Self-retaining laryngoscope

Objective To investigate the treatment of vocal process granuloma with semiconductor laser, and to analyze the reasons for recurrence of vocal process granuloma after operations.Methods Fourteen cases of patients with vocal process granuloma. Semiconductor laser wavelength was 810 nm, and the fiber diameter was 0. 6 mm. The output power of the laser was 0. 5-30 W, which was continuously adjustable. Combined with the self-retaining laryngoscope under a microscope, the granuloma was coagulated and vaporized by laser under contact and non-contact mode. Results Fourteen patients were followed up for 2-4 years, 11 cases of them were cured after one-time treatment, two cases recovered after the second treatment. Cure rate of 78. 6% after one time treatment. Vocal cord function resumed with no significant complications. Then the criterion of efficacy determination was developed.Conclusions Using semiconductor laser with self-retaining laryngoscope to remove vocal process granuloma is a more advanced clinical means, which is significantly effective and reduces recurrence. And it is also a good supplemental treatment for post-operative recurrence of vocal process granuloma by traditional laryngoscope surgery. So this method is worth promoting in appropriate hospitals.
