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.
