Short and intensive therapy with finger kazoo in patient with organic dysphonia post-orotracheal intubation

Abstract

Objective: to evaluate the effect of a program of brief and intensive therapy with finger kazoo technique in adult female patient with organic dysphonia. Presentation of the case: were realized aerodynamic, acoustic, perceptual, videolaryngostroboscopic measures and vocal self-assessment before and after 15 sessions of short and intensive therapy with finger kazzo technique in a 62 years woman with organic dysphonia by fibrosis in the right vocal fold, glottis of irregular type with phase asymmetry and amplitude, and edema of the glottis and contraction of the anterior portion of the right vestibular fold due to endotracheal intubation. Results: After therapy, there was improvement of maximum phonation time, acoustic frequency measurements, frequency of disturbance noise, sub-harmonic segments, improved stroke spectrographic and all perceptual parameters, as well as improvement of quality of life scores, depression and anxiety. In the videolaryngostroboscopy evaluation, there was improvement in range of mucosa vibration of the vocal folds and reduction of medial constriction of the laryngeal vestibule. Conclusion: there were positive vocal changes in glottic, respiratory and resonant level, videolaryngostroboscopy and vocal self-assessment, emphasizing that this was an effective treatment modality for the case.
