Abstract

BACKGROUND AND OBJECTIVES
The objectives were to analyze the results of the laryngeal framework surgery (LFS) in one institute during 12 years. We reviewed the present position of LFS in the phonosurgery field and discussed the prospects for this type of surgery in the future. SUBJECTS AND METHOD: One hundred seventy nine charts of patients who underwent LFS in Yongdong Severance hospital from 1992 to 2003 were reviewed. Types of procedures were made according to the classification/ nomenclature of European Laryngological Society. RESULTS: One hundred ninty seven operations had been performed during 12 years in 179 patients. Type I thyroplasty was the most common procedure (28.9%). Type I thyroplasty+Arytenoid adduction (26.4%), Type III thyroplasty (16.8%), Arytenoid adduction (15.2%), Injection medialization (11.2%), Type IV thryroplasty (1.5%) followed in the order of most commonly operated choices. Of 197 cases, 18 cases were revision. There was only one major complication (dyspnea). A variety of dysphonias, which include vocal fold paralysis (71.5%), various pitch problems (mutational dysphonia (14%), androphonia (1.1%)), glottal insufficiency (12.8%), and some cases of spasmodic dysphonia (0.6%), had been treated with LFS. CONCLUSION: Laryngeal framework surgery is a new type of surgery that aims to improve the voice by restructuring the laryngeal framework. This type of surgery has become increasingly popular, because it has been found to be safe and effective.
