Fat Augmentation for Glottic Insufficiency

Autogenous fat augmentation for glottic insufficiency has commonly been administered in patients with vocal fold paralysis. The purpose of the present study was to evaluate the efficiency of autologous fat injection for cases of deficiency of glottal closure such as sulcus vocalis, laryngeal trauma and postoperative scarring. Fat injection was performed on 4 cases of sulcus vocalis and 3 cases of postoperative scarring with laryngeal trauma. Phonatory function and videolaryngostroboscopic data were evaluated before and after the augmentation. After the operation, improvement in wave motion during phonation was observed. Also, in many cases, maximum phonation time was extended. Even in cases where phonation time was not extended, ease of phonation was subjectively recognized. The results of the study suggest that autogenous fat injection may be effective for 東海 大学 医学 部付 属東 京病 院耳 鼻咽 喉科1):〒151-0053東 京 都 渋谷 区代 々木1-2-5 国 際医療 福祉 大学 東京 ボイス セ ンター2):〒107-0052東 京都 港 区赤坂8-5-35 聖母 会聖 母病 院耳 鼻咽 喉科3):〒161-8521東 京都新 宿 区 中落:合2-5-1 1) Department of Otorhinolaryngology, Tokai University School of Medicine: Tokai University Tokyo Hospital: 1-2-5 Yoyogi, Shibuya-ku, Tokyo 151-0053 2)Tokyo Voice Center , International University of Health and Welfare: 8-5-35 Akasaka, Minato-ku, Tokyo 107-0052 3)Department of Otorhinolaryngology , International Catholic Hospital: 2-5-1 Nakaochiai, Shinjuku-ku, Tokyo 161-8521 2005年4月13日 受稿2005年5月26日 受理
