Supracricoid laryngectomy: age influence on long-term functional results

: Supracricoid laryngectomies (SCL) are conservative surgical techniques for the treatment of selected laryngeal carcinomas, currently adopted also in old patients. Long-term functional results have not been reported in elderly patients. The aim of this study is to compare voice and swallowing in elderly and younger patients following SCL.

: Cross-sectional study.

: Twenty male patients who underwent SCL were recruited in the study; 10 were younger than 65 years at the time of surgery and 10 were older. Video-endoscopic ratings were taken of neoglottic vibration patterns and bolus transit. Voices were perceptually rated using the GIRBAS scale. The maximum phonation time (MPT) and the syllables diadochokinesis were measured. Spectrograms were recorded. All of the patients completed a self-assessment questionnaire for both voice and swallowing. The data obtained from the two groups were compared through the Mann-Whitney test.

: Video-endoscopic ratings of neoglottal vibration and bolus transit showed no difference between the two groups. The perceptual assessment showed a harsh voice in both groups. No significant difference was found for mean syllable diadochokinesis and the mean MPT was 6.3 seconds and 8.8 seconds, respectively in the younger and older group. The mean value of the Yanagihara scale of voice spectrogram was 3.8 and 3.7. Voice and swallowing quality-of-life questionnaires revealed satisfied patients in both age groups.

: Age by itself does not have a significant impact on long-term functional results following SCL. Meticulous selection of the candidate to SCL allows the application of this surgical technique with adequate long-term functional results. Laryngoscope, 2009.
