Surgical Management of Tonsil Cancer / 대한이비인후과학회지

ABSTRACT

BACKGROUND AND OBJECTIVES: Surgery and postoperative radiation therapy have been the main stream management of tonsil cancer. There is a variety of surgical approach methods are used for the resection of tonsil cancer, however, there have only been a few reports of the results of surgical treatment of tonsil cancer. So, on the basis of our experience, we report the results of our surgical treatments of tonsil cancer. SUBJECT AND METHOD: 32 medical records, from 1994 April to 2003 June, of patients surgically treated for tonsil cancer were reviewed. Evaluated were disease status, surgical approach methods, types of the neck dissection, surgical margin, reconstruction methods, postoperative complications, time of oral diet and decannulation, recurrence, and survival rate. RESULTS: Mean follow up periods were 2.3 years. There was 1 patient in Stage I, 5 in Stage II, 2 in Stage III, and 24 in Stage IV. For Tumor excision, 5 patients underwent intraoral approach, 10 mandibulotomy approach, and 17 lateral pharyngotomy approach. Surgical defects were primary closed in 5 patients and reconstructed with pectoralis major myocutaneous flap in 7 patients and radial forearm fasciocutaneous free flap in 20 patients. There were 2 local recurrences, 5 regional recurrences, and one distant metastasis. The mean time of the beginning of oral diet/decannulation after operation were 19.8/11.3 days in lateral pharyngotomy and 25.3/12.9 days in mandibulotomy. The mean survival period was 41.4 months. CONCLUSION: Because most of tonsil cancers are advanced diseases, more precise tumor resection and meticulous neck management are needed. Lateral pharyngotomy approach had priority to other surgical approaches in selected cases except T4. It has advantages of full range of vision for resection, better functional status and less postoperative morbidity.
