摘要

Although used for treating vascular malformations, KTP (532 nm) lasers have not been used to treat microvascular lesions of the vocal fold. The efficiency of KTP laser operation in the continuous mode with a 0.4- or 0.6-mm beam (1- to 2-W aim for 3 to 7 seconds delivering a total energy of 3 to 7 J) was studied retrospectively in patients with microvascular lesions of the vocal fold (n = 14). The perceptual acoustic, phonatory function, and videolaryngostroboscopic data were evaluated before and after operation in 10 patients. At follow-up (mean, 7 months), the results were excellent in all patients. Their phonatory function (jitter, shimmer, grade, breathiness, and roughness) significantly improved (p < .01). The videolaryngostroboscopic rating showed significant improvement in the amplitude of vocal fold vibration and excursion of the mucosal wave (p < .05). No postoperative recurrence or complications were noted. The KTP laser operation is a useful, cost-effective, and time-saving procedure and can be considered as an option in management of patients with microvascular lesions of the vocal fold, particularly those with repeated hemorrhages. Because the operation is easy (compared to other surgical methods) and has no major side effects, the prospect of total patient recovery is excellent.
