Abstract

Background and Objectives: The aim of this clinically feasible study was to show the preliminary result regarding postoperative outcomes of in-office laser surgery for a benign laryngeal lesion.
Materials and Methods: This clinically feasible trial included 12 patients suffering from various laryngeal pathology. Vocal fold polyp was most common (n=3), followed by granuloma (n=2), papillomatosis (n=2), and glottal leukoplakia/dysplasia (n=2). Laser vaporization was performed using the diode laser set at 12 W output power and a fiberoptic laryngoscope.
Results: None of the patients showed complication. Three cases of vocal polyp were cured by a single procedure. In cases of leukoplakia and laryngeal hair, the lesion was significantly improved but required repeated procedures. In contrast, patients with contact granuloma, subglottic stenosis, and tracheal lesion showed partial remission with laser surgery. Only one patient required conversion to general anesthesia after office-laser surgery; this patient had laryngeal papillomatosis with an invisible surface and inappropriate exposure, making it difficult for the fiberoptic endoscope to reach the lesion.
Conclusion: Efficacy of in-office laser surgery for benign laryngeal disease is comparable to that of conventional laryngeal microsurgery under general anesthesia. Further comparative study is necessary to elucidate the long-term results.
