Supracricoid laryngectomy (SCL) is an efficient surgical procedure for the treatment of selected laryngeal carcinoma, presently being performed not only in Europe but also in North America. The functional goals of the technique are voice and swallowing without a permanent tracheostomy. Perceptual and acoustic voice characteristics after SCL have been reported by different authors, but self-assessment data together with subjective and objective data have only been reported for a small number of subjects. 20 male subjects, with a mean age of 71 years (range 51-82) who underwent a SCL at least one year before our observation, were included in the study. Each subject underwent a flexible laryngoscopy and his voice was perceptually rated using the GRBAS scale. Objective examination included: maximum phonation time (MPT), voice spectrograms and syllable diadochokynesis on a single breath. Finally, each subject assessed his own voice using the Voice Handicap Index (VHI). The mean values of the GRBAS scale were respectively 2.4, 2.6, 2.4, 0.8, 0.5, 0.8. Mean MPT was 7.5 sec., while, for voice spectrograms the mean value of the Yanagihara scale was 3.7. Mean syllable diadochokinesis appeared as 3.3 syll/sec. Mean value of the VHI was 29.9. Subjective and objective data show a severely dysphonic voice after SCL; self-assessment data, on the contrary, reveal only moderate functional and emotional consequences. While perceptual, aerodynamic and acoustic data are in line with previous reports, self-assessment data were less severe in our subjects compared to what appears in the literature. It is concluded that self-assessment explores a different dimension of the patient’s voice and that even if a severe dysphonia is present the consequences on everyday oral communication are only moderate.

Abstract
Supracricoid laryngectomy (SCL) is an efficient surgical procedure for the treatment of selected laryngeal carcinoma, presently being performed not only in Europe but also in North America. The functional goals of the technique are voice and swallowing without a permanent tracheostomy. Perceptual and acoustic voice characteristics after SCL have been reported by different authors, but self-assessment data together with subjective and objective data have only been reported for a small number of subjects. 20 male subjects, with a mean age of 71 years (range 51-82) who underwent a SCL at least one year before our observation, were included in the study. Each subject underwent a flexible laryngoscopy and his voice was perceptually rated using the GRBAS scale. Objective examination included: maximum phonation time (MPT), voice spectrograms and syllable diadochokynesis on a single breath. Finally, each subject assessed his own voice using the Voice Handicap Index (VHI). The mean values of the GRBAS scale were respectively 2.4, 2.6, 2.4, 0.8, 0.5, 0.8. Mean MPT was 7.5 sec., while, for voice spectrograms the mean value of the Yanagihara scale was 3.7. Mean syllable diadochokinesis appeared as 3.3 syll/sec. Mean value of the VHI was 29.9. Subjective and objective data show a severely dysphonic voice after SCL; self-assessment data, on the contrary, reveal only moderate functional and emotional consequences. While perceptual, aerodynamic and acoustic data are in line with previous reports, self-assessment data were less severe in our subjects compared to what appears in the literature. It is concluded that self-assessment explores a different dimension of the patient’s voice and that even if a severe dysphonia is present the consequences on everyday oral communication are only moderate.Pubblicazioni consigliate
