This study assessed the functional results in patients treated primarily through supracricoid partial laryngectomy (SCPL) with cricohyoidoepiglottopexy (CHEP).

Fifteen patients with a diagnosis of epidermoid carcinoma of the glottis region admitted to the Instituto Nacional de Cancerología (México) between June 2001 and September 2002 were studied. Three patients were at stage I, five at stage II, six at stage III, and one at stage IV. Both cricoarytenoid units were preserved in 12 patients, and only one in three. Each case was assessed through the clinical grading postoperative aspiration (CGPA) scale, the performance status scale for head and neck cancer (PSS-HNC), and the Karnofsky Performance Scale (KPS). Likewise, voice quality of the patients was assessed regarding tone and intensity using the SpeechViewer version 1 (IBM) and data were obtained with the Cool Edit 2000 software.

Twelve patients received phoniatric rehabilitation and three were left without rehabilitation. The average time for decannulation was 12 days and 23 days for removal of the nasogastric catheter. The degree of aspiration was 0 in four patients and one in 11. According to PSS-HNC, the mean for normalcy in the diet was 95 and the mean for those eating in public was 91. Intelligibility reached an average of 90. Karnofsky’s assessment was related to the disease and not to the treatment, as it remained at 100 per cent in most patients and was never below 80 percent. The mean intensity of quality of voice was -18 dB below normal; however, the mean frequency was 243.7 Hz.

SCPL and CHEP allows the preservation of the basic function of the larynx; however, a clear alteration in voice occurs after the procedure, although normal frequency is kept when both arytenoids are preserved. Likewise, preservation of both arytenoids shortens the time needed for cannula and feeding catheter removal. PSS-HNC, Karnofsky, and CGPA assessments demonstrated thatpatients can reach an almost normal bio-psycho-social integration. It is recommended that all patients be subjected to phoniatric rehabilitation.
