다국어 초록 (Multilingual Abstract)

Background and Objectives：Salvage surgery for recurrent glotic cancer after radiation failure has been reported in the li-terature as a treatment for total laryngectomy and partial laryngectomy (vertical partial laryngectomy, supracriocoid partial la-ryngectomy) in selected cases. Also, CO2glotic cancer. However, salvage laser surgery for recurrent glotic cancer has been rarely reported. Our experience of transoral laser cordectomy on recurent glottic cancer after radiotherapy is reported. Subjects and Method：Twelve patients with early recurrent glottic cancer after full-course radiotherapy (rT1a, n= 4；rT1b, n= 1；rT2, n= 7) underwent laser cordectomy between October, one type IV, and eight type V performed. One patient underwent type II at one side and type II at the other. Surgery in all the cases were performed at one stage with curative intent. Results：The mean follow-up interval was 30 months (range 17- 44 months) with five out of 12 cases (42% ) having local recurence. Four of the five cases with local recurence underwent total laryn-gectomy. Thre cases were salvaged while one had additional recurence. The other one was under palliative treatment. The local (range 2- 26 days) after surgery, and tracheotomy was performed in four cases (duration：3- 20 days). There was no postope-rative aspiration pneumonia and nasogastric tube was not performed in any of the cases. Conclusion：Transoral laser microsurgery may be a feasible salvage method for recurent glottic cancer to gain oncologic and functional results, and could be used as an or-gan-preserving procedure with curative intent in selected cases.
