[Horizontal supraglottic laryngectomy. Technique, indications, oncologic results and early functional results....

In this article, we advocate supraglottic laryngectomy with bilateral neck dissection for the treatment of supraglottic carcinomas with preserved laryngeal mobility. Post-operative results and follow-up of 87 patients are discussed. This technique allows an excellent loco-regional control of the disease with preservation of laryngeal function. Radiation therapy is preserved for treatment of metachronous (2nd primary) in cases with satisfactory local control without neck metastases. All stage 5-year overall survival rate was 55% with a 68.5% disease survival rate. Five-year local control of the disease and regional control of neck nodes were respectively 94% and 92%. Five-year disease survival rate for N- population was 71% Vs 61% for N+ population. Five-year disease survival rate according to the tumor classification was 70% for T1, 75% for T2, 69% for T3 and 54% for T4. In the post-operative follow-up, the median of time to decanulation was 17 days, that of nasogastric tube removal was 19 days, that of hospital stay 38 days.
