“…Recent meta-analysis has defined a mean increase in F0 after glottoplasty of 78 Hz, a higher value than in our study. 23 We believe that these different findings are due to the fact that most of the authors included in the meta-analysis performed varying degrees of postoperative speech therapy before the acoustic analysis of the voice. 18 , 22 , 34 , 35 In isolation, speech therapy has the potential of increasing 31 Hz in F0, 15 which may have overestimated the specific power of glottoplasty to raise the pitch in these studies.…”

“…Können die persönlichen Erwartungen jedoch nicht erfüllt werden, sind phonochirurgische Eingriffe indiziert. Der Erfolg der Glottoplastik bezieht sich auf die signifikante Erhöhung der mittleren Sprechstimmlage, verringert jedoch die maximale Phonationsdauer und verschlechtert z. T. die Stimmqualität [21]. Somit kann durch operative Intervention das Kriterium einer angehobenen mittleren Sprechstimmlage erfolgreich erfüllt werden, wohingegen aber andere objektive Parameter in ihrer Leistung abnehmen können.…”

“…reFerenCes infection or dysphagia have been identified on systematic review of the WG literature. 50 Some data exist to suggest that glottoplasty causes postoperative dysphonia; a meta-analysis of three studies including 70 patients reported that auditory perceptual evaluation of overall voice quality graded on the GRBAS scale worsened by 0.44 after glottoplasty. 50 This degree of worsening represents a half-step worsening on a four-point scale with gradations of normal, mild, moderate, and severe dysphonia; the clinical significance of this degree of change is unclear.…”
