title: [Evaluation of dysphonia in partial laryngectomy patients].
abstract: OBJECTIVE
  The purpose of this study was to research and compare the affects of cordectomy, frontolateral laryngectomy or cricohyoidopexy techniques over voice parameters prospectively.
  
  
  METHODS
  Fifty-six larynx cancer patients (56 males; mean age 59; range 48 to 71 years) whom cordectomy, frontolateral laryngectomy or cricohyoidopexy was applied in S.B. Izmir Training Hospital were included in this study. In the subjective evaluation of the patients voices and RBH scoring, in the aerodynamic evaluation, MPT measurements and in the objective evaluation computerized voice analysis was used. In calculating the dysphonia severity index (DSI), this formula (DSI=0.13xMPT+0.0053xF0 (high)-0.26xI (low)-1.18x jitter (%)+12.4) was used.
  
  
  RESULTS
  In the subjective (RBH) evaluation of voices of these three group of patients and their DSI scores, there wasn't any statistically differences among them. When arytenoidectomized patients were evaluated as a separate group, this procedure was found not to have a significant impact over DSI.
  
  
  CONCLUSIONS
  From phoniatric point of view, there wasn't any difference of cordectomy, frontolateral laryngectomy or cricohyoidopexy techniques over voice.
