[Conservative surgery for supraglottic carcinoma. Surgical technique. Oncologic and functional results].
We present the results of a retrospective study of 817 patients treated with conservative surgery for carcinomas of the supraglottic larynx at ENT department of the Gregorio Maranón Hospital between 1962-1993. The disease was staged using the criteria set forth in 1988 by the AJCC, and 36,2% were stages III and IV. From the 817 patients treated with conservative surgery 230 were extended supraglottic laryngectomies. Our theoretic treatment protocol is presented. The 5 years actuarial uncorrected survival rate related to stage was 83,9%, 83,2%, 78,5% and 55,3% for stages I, II, III and IV respectively. Local-regional failure occurred in 32,9% patients overall, and the most common site for local-regional failure was the cervical nodes. The 5 years local control rate related to stage was 86,97%, 89,1%, 82,15% and 66,55% for stages I, II, III and IV respectively. In extended supraglottic laryngectomies the 5 years uncorrected survival rate was 62,6% in supraglottic laryngectomies (SL) extended to the base of the tongue, 62,5% in SL extended to the hypopharynx, 72,5% in SL extended to the arythenoyd and 79,4% in SL extended to the vocal chord. The 5 years local control rate was 87% in SL extended to the base of the tongue, 85,7% in SL extended to the hypopharynx, 97% in SL extended to the arythenoid and 90,8% in SL extended to the vocal chord. Functional results have been evaluated according to a three grade scale. Good and fair results were 97.6% for swallowing, 90% for respiration and 95.8% for the quality of voice.
