Between October 1987 and October 1993, 92 patients with squamous cell carcinoma of the supraglottis were treated by supraglottic laryngectomy and neck dissection in our department. There were 33 T1, 46 T2, six T3 and seven T4 cases. All patients with N+ necks and T3 or T4 tumours received post-operative radiotherapy (5,000–6,500 cGy). The patients were followed for a minimum of 36 months or until death. The incidence of local recurrence was 7.6 per cent. Neck recurrence was observed in 13 per cent of patients. Decannulation was achieved in 93.4 per cent of the cases with three patients undergoing gastrostomy because of aspiration. The average hospital stay was 26 days. The overall three-year survival was 83.6 per cent, with eight patients dying of unrelated causes. There was a significant difference in recurrence rate between patients in the N0 and the N+ stage.
