OBJECTIVE: To compare the oncological and functional outcomes in patients undergoing supracricoid partial laryngectomy with other traditional partial laryngectomy. METHOD: One hundred and fourteen patients treated from 1992 to 2007 were selected from all laryngeal cancer patients undergo partial laryngectomy through random match method by tumour subsite, TNM stage and age. Among them, 58 were supraglottic cancers, 56 were glottic cancers. Patients were divided into supracricoid laryngectomy group and other partial laryngectomy group. Each group includes 57 cases. We compare the 3-year and 5-year actuarial survival, local control rate and decannulation rate between two groups. RESULT: The 3-year and 5-year actuarial survival estimate was 90% and 87% for supracricoid partial laryngectomy, 97% and 92% for other partial laryngectomy (P > 0.05); Local control rate estimate was 94.2% for supracricoid laryngectomy and 91% for other partial laryngectomy(P > 0.05); Decannulation rate was 98% for supracricoid laryngectomy and 89.5% for other partial laryngectomy(P>0. 05); The decannulation was ever lower in horizontal-vertical partial laryngectomy than supracricoid partial laryngectomy (75% versus 98%, P < 0.01). CONCLUSION: Comparing with other partial laryngectomy, supracricoid partial laryngectomy seems to have higher decannulation rate and is a considerable choice for selected laryngeal cancer.
