title: Evaluation of voice quality after supraglottic laryngectomy.
abstract: OBJECTIVE
  Supraglottic laryngectomy is a surgical procedure that preserves laryngeal functions. This technique allows extensions including removal of tongue base or 1 arytenoid. We aimed to compare vocal results of supraglottic laryngectomy and extended procedures.
  
  
  METHODS
  Cross-sectional study.
  
  
  METHODS
  Tertiary care hospital.
  
  
  METHODS
  Thirty-three males who underwent supraglottic laryngectomy were included in the study. Fifteen patients (45.5%) were applied standard supraglottic laryngectomy (standard supraglottic laryngectomy group). In 11 patients (33.3%), unilateral arytenoid cartilage was totally resected by separation at the cricoarytenoid joint (laterally extended group), and the tongue base was removed in 7 patients (anteriorly extended group) (21.2%). Twenty male smokers constituted control group. Acoustic and aerodynamic voice analyses were performed for the assessment of objective results. Grade, roughness, breathiness, asthenia, and strain scale (GRBAS) scores were analyzed for perceptual assessment. Voice Handicap Index-30 was used to evaluate subjective results.
  
  
  RESULTS
  The comparison of supraglottic laryngectomy group with the control group revealed that the mean maximum phonation time and fundamental frequency were significantly lower in the supraglottic laryngectomy group (P < .001), and the mean jitter, shimmer, and noise-to-harmonics ratio were significantly higher in the supraglottic laryngectomy group (P < .001). Maximum phonation time and fundamental frequency were higher in the standard supraglottic laryngectomy group in comparison to extended groups. Jitter value was also lower in the standard supraglottic laryngectomy group compared to extended groups. Perceptual and subjective analyses revealed no difference among standard supraglottic laryngectomy and extended groups.
  
  
  CONCLUSIONS
  The results of this study indicate that supraglottic laryngectomy patients have acceptable voice quality, as determined by perceptual and subjective assessment.
