Long-term Clinical Outcomes of Supracricoid Partial Laryngectomy with Cricohyoidoepiglottopexy for Glottic Carcinoma

Laryngeal carcinoma should be treated with the intent of organ-sparing, and supracricoid partial laryngectomy with cricohyoidoepiglottopexy (CHEP) might be an important option. The purpose of this study was to evaluate the clinical outcomes of glottic carcinoma patients treated with CHEP. A series of 164 cases with glottic carcinoma undergoing CHEP from 2006 to 2010 was retrospectively analyzed. The 10-year overall survival (OS) rate, disease-specific survival (DSS) rate, and disease-free survival (DFS) rate were 77.6%, 78.8%, 74.1%, respectively. The OS, DSS, and DFS of patients with stage T1 were higher than patients with stages T2 and T3. Patients with locoregional recurrence and distant metastases had lower OS and DFS than patients with neither recurrence nor metastasis. The DFS of patients with advanced laryngeal carcinoma was worse than that of patients with early-stage carcinoma. T2 and T3 stages, locoregional recurrence, and distant metastases had predictive value regarding patient survival. Additionally, the decannulation rate of postoperative patients was 95.1%, and the nasogastric feeding tube removal rate was 100%. CHEP provided reliable oncologic and functional outcomes, and it should be considered as a standard function-sparing option for glottic T1b, T2, and selected T3 carcinoma patients.
