Abstract

Background and Aim: Reflux laryngitis is extremely common among patients with voice disorder. Medical therapy approaches are not efficient enough. The main goal of this study is to assess the acoustic and laryngeal characteristics of patients with dysphonia before and after medical or voice therapy, and to evaluate the effectiveness of each.
Methods: In this retrospective study, 16 reflux laryngitis patients were assessed. Five received complete voice therapy, tow ceased voice therapy and nine received medication. Perceptual voice evaluation was performed by a speech-language pathologist, the severity of voice problem was calculated, based on the affected acoustic and laryngeal characteristics pre- and post-treatment.
Results: Post-treatment evaluation in patients who received complete voice therapy indicates 80 percent improvement in the severity of disorder and 100 percent improvement in the perceptual voice evaluation. After medical therapy, we observed that voice disorder and perceptual voice evaluation are improved 44 and 66 percent respectively. The improvement was statistically significant in both treatment approaches: complete voice therapy (P=0.039) and medical therapy (p=0.017).
Conclusion: In patients with reflux laryngitis, most acoustic and laryngeal characteristics were normal and satisfying after the treatment. It can be concluded that the proficiency of voice therapy in improving the acoustic and laryngeal characteristics is comparable to medical therapy.

Abstract

Background and Aim: Vocal cord nodule is one of the voice disorders causes hoarseness and breathy voice. Voice therapy is one of the treatment approaches. We aimed to find out the effects of voice therapy on vocal acoustic characteristics in these patients.
Methods: In this case series, five women with vocal nodule (14 to 45-year-old) participated in a 9-week voice therapy program developed by Boone. Vocal hygiene and voice practices were measured every day using a questionnaire. Moreover, structure and movements of vocal folds were examined using videolaryngostroboscope by a laryngologist before and after voice therapy to evaluate the effectiveness of program. For collecting voice samples we used sustained /æ/ in comfortable loudness for all patients and data were analyzed using Speech Studio.
Results: After voice therapy, fundamental frequency in four of five subjects were decreased but it was not significant (p=0.225). However, jitter in all of five subjects was significantly decreased (p=0.043). After voice therapy, shimmer in three of five subjects were decreased that was not significant (p=0.345).
Conclusion: Voice therapy can be used for the remedy of acoustic vocal characteristics and elimination or contraction of vocal cord nodule.

Abstract

Background and Aim: An imbalance between phonatory subsystems may lead to disturbing phonatory muscular balance and consequently voice disorders. Based on theoretical issues, criterion-based laryngeal manual therapy, as a novel treatment method which is supported by classical laryngeal manual therapy, can improve voice quality using manual maneuvers combined with phonatory tasks. The present study aimed to report the treating effects of this method on hyperfunctional voice disorders.

Methods: Twenty adult participants with hyperfunctional voice disorders by the least three months history of voice disorder were selected. The participant’s voices were assessed multidimensionally using acoustic, audio-pecreptual and stroboscopic assessments before and after treatment.

Results: There were a decrease in jitter (p=0.003) and shimmer (p<0.001) and also, increase in harmonic-to-noise ratio (HNR) (p<0.001) of vowel /a/ after treatment. Besides, there was an increase in harmony to noise ratio (p=0.009) and decrease in jitter (p=0.020) of vowel /i/, too. There were not significant changes in shimmer amount of vowel /i/ (p=0.170) after treatment. There were highly significant changes in all aspects of audio-perceptual (p<0.001) and videostroboscopic (p<0.001) parameters.

Conclusion: Using voice-based laryngeal manual therapy can be a treatment method in handling hyperfunctional voice disorders.
