목적: The ideal timing of therapeutic neck dissection in relation to transoral lateral oropharyngectomy has not yet been defined for tonsil cancer. This study aims to report the outcomes of a single center’s experience with the two-stage operation in the surgical treatment of tonsil cancer with cervical lymph node metastasis. 방법:A retrospective analysis was performed of patients undergoing transoral lateral oropharyngectomy with intent to proceed to neck dissection at Guro hospital of Korea University from October 2008 to January 2020. The demographic data, tumor characteristics, surgical records, complications, adjuvant treatments, disease recurrence, and survival outcomes were analyzed. 결과:7 patients were identified who underwent two-stage operation of transoral lateral oropharyngectomy and neck dissection. All patients underwent timely surgical treatments without intraoperative complications. A single post-operative complication occurred, involving chyle leakage necessitating repair under general anesthesia. Notably, no other complications, such as bleeding, airway obstruction, or pharyngocutaneous fistula, were observed. Throughout the follow-up period(range 41–107 months), there were no instances of cancer recurrence or mortality. 결론:The short interval between transoral lateral oropharyngectomy and neck dissection surgeries did not negatively impact results, with no instances of cancer recurrence or mortality observed.
