Voice and Deglutition Functions after the Supracricoid and Total Laryngectomy Procedures for Advanced Stage Laryngeal Carcinoma
2003
OBJECTIVES: The investigation compared speech and deglutition functions after alternative surgical treatments for advanced stage laryngeal carcinoma: the supracricoid laryngectomy (SCL) versus the total laryngectomy (TL).STUDY DESIGN AND SETTING: Cohort investigation at Wayne State University School of Medicine.METHODS: Quantitative studies of laryngeal biomechanics, acoustic and speech aerodynamic features, and deglutition skills of these individuals were coupled to listener and patient self-impressions of speech and voice characteristics for group comparative analyses.RESULTS: Results revealed that patients from each subgroup performed comparably relative to speech intelligibility and voice quality disturbances. Videostroboscopy of the neoglottal mechanisms in these two populations helped to explain these outcomes. Acoustic and speech aerodynamic testing demonstrated variably abnormal features in both surgical subgroups. Whereas the SCL patients eventually achieved full oral diets, they required many se...
