OBJECTIVE: The aim of the study is the clinical investigation of a patient with a vocal fold polyp, and the visual, acoustical, perceptual, and self-report changes before and after using the cricothyroid visor manoeuvre (CVM). DESIGN: A 48-year-old female university professor, gynecologist, and obstetrician with a history of laryngopharyngeal reflux and a left vocal polyp participated. Treatment was provided in 10 sessions. Pre- and post-treatment audio recordings of sustained vowels, selected sentences, and connected speech samples were submitted to auditory-perceptual and acoustical analysis to assess the effects of the two-treatment program. Also, laryngoscopic images, perceptions by the patient about her voice quality and quality of life before and after therapy were assessed. RESULTS: Improvements in acoustic parameters were obtained especially in perturbation and CCPS parameters. The overall voice quality scores on the CAPE-V were moderate before therapy and became mild after therapy. Laryngoscopy images demonstrated improvement in the glottis closure configuration in two phases (open and close) in pre- and post- CVM therapy and a decrease in polyp size. The patient had improvement in VAS, IVQLP, and VRQOL scores. CONCLUSION: The CVM therapy used in the study resulted in positive changes in acoustic and perceptual-auditory aspects of voice production, self-report, and QOL for the patient. The CVM approach appears to have been effective for this case in decreasing the polyp size or its regression or for vocal adaptation.
