Comparative Study between Transoral Laser Microsurgery and Transoral Videolaryngoscopic Surgery in Benign Laryngeal Tumors

  • 1Department of Otolaryngology-Head and Neck Surgery, Kosin University College of Medicine, Busan, Korea


Background and Objectives
Surgical resection is the basic treatment for benign laryngeal tumors and transoral laser microsurgery (TLM) has been used effectively. Transoral videolaryngoscopic surgery (TOVS) is another method of surgical resection that has been introduced. However, there have not been any studies related to the usefulness of TOVS in benign laryngeal tumors. The purpose of this study was to compare the efficacy and surgical outcomes of TLM and TOVS. Subjects and Method A retrospective chart review of 85 patients were conducted. This review included two groups (TLM group, n=44 versus TOVS group, n=41) of patients who underwent transoral surgery for benign laryngeal tumors. Clinicopathologic factors of the patients and surgical outcomes such as the operation time, amount of intraoperative bleeding, hospital stay, and complications were compared between two groups.
There were no significant differences between two groups regarding the clinicopathologic factors and surgical outcomes. The TOVS group presented relatively larger tumor size (p=0.067) and showed a tendency of shorter operation time (36.8±34.5 min) compared to that of TLM (45.6±27.9 min), but with no statistical significance (p=0.199).
TOVS may be considered as an alternative surgical method for benign laryngeal tumors.
