Is electroglottography-based videostroboscopic assessment of post-laryngectomy prosthetic speech useful?
OBJECTIVES: To use an electroglottography (EGG)-based videostroboscopy tool to assess the anatomical and morphologic characteristics of the pharyngoesophageal (PE) segment in tracheoesophageal (TO) speakers. STUDY DESIGN: Cross-sectional cohort study. SUBJECTS: Fifty-two post-laryngectomy patients with no recurrence and using prosthetic (Blom-Singer) speech. INTERVENTION: An electroglottography (EGG)-based videostroboscopy tool EGG-based rigid videostroboscopy as well as perceptual evaluation. OUTCOME MEASURES: Stroboscopic protocol included nine subjective/visual parameters to evaluate the neoglottis and study correlation of the G (GRBAS scale) and the overall voice quality (OVQ) with the treatment variables. RESULTS: Of the 52 laryngectomees, videostroboscopic recordings were possible in 46 patients (36 males and 10 females) with a mean age of 63.4 +/-10.5 (SD) an electroglottography (EGG)-based videostroboscopy tool years. All used the Blom-Singer valve and the median time since Tot
