Vocal Fold Nodules | ScienceGate

Abstract Many children with dysphonia present with benign vocal fold lesions, including bilateral vocal fold nodules, cysts, vocal fold varices, and scarring. Evaluation and treatment of these children are best undertaken in a thoughtful and coordinated manner involving both the speech-language pathologist and the otolaryngologist. The goals of this article are (a) to describe the team evaluation process based on a “whole system” approach; (b) to discuss etiological factors and diagnosis; and (c) to review current medical, behavioral, and surgical treatments for children with different types of dysphonia.

Vocal Fold Nodules

Benign laryngeal lesions represent a diverse set of pathologies whose clinical presentation may range from no symptoms to dyspnea and/or dysphonia. Flexible fiberoptic laryngoscopy and videolaryngostroboscopy are important in distinguishingdifferent types of lesions, and management and treatment are dependent on the identification of these lesions, as they have different etiologies. Some lesions such as vocal fold nodules and polyps are primarily phonotraumatic and may benefit fromspeech therapy and vocal hygiene as initial approaches. Vocal fold cysts and benign tumors may benefit from microlaryngeal approaches, while capillary ectasias, polypoid corditis, laryngoceles, saccular cysts, and papilloma may benefit from laser therapy. Vocal fold granulomas may arise from various etiologies such as intubation, traumatic behaviors, or reflux. Polypoid corditis arises from smoking. This review is intended to provide an overview of the variety of lesions that encompass non-malignant laryngeal lesions that is both suitable for junior and senior residents.

Introduction. There are subjective and objective ways to examine the effects of vocal therapy in voice disorders. The most precise and objective check-up is the use of computer voice analysis. Objective. The aim of the research was to perform a detailed analysis of acoustic structure of the vowel A before and after voice treatment in patients with vocal fold nodules in order to obtain objective verification of the vocal rehabilitation success. Methods. We examined 30 female patients, aged 34.6?6.69 years, with vocal fold nodules. Acoustic parameters of voice were compared with the control group consisting of 21 subjects without voice pathology. In all persons the vowel A was recorded and analyzed before and after a month of vocal therapy. The success of the vocal therapy was tracked using computer analysis of vocal structure. Signal, noise and tremor parameters were processed. Results. Of the analyzed vowel A parameters: STD, PER, JITA, JITT, RAP, vFO, ShdB, SHIM, APQ, VTI, SPI, F0, NHR, FTRI, eleven improved (p<0.05 and p<0.01). Three parameters (F0, NHR, FTRI) changed showing improvement, but the obtained differences were not statistically significant (p>0.05). Conclusion. Based on the obtained results it was concluded that vocal therapy gave satisfactory results, but that it should be continually applied until full stabilization of the voice.

Vocal Fold Nodules

Purpose Ambulatory voice biofeedback (AVB) has the potential to significantly improve voice therapy effectiveness by targeting one of the most challenging aspects of rehabilitation: carryover of desired behaviors outside of the therapy session. Although initial evidence indicates that AVB can alter vocal behavior in daily life, retention of the new behavior after biofeedback has not been demonstrated. Motor learning studies repeatedly have shown retention-related benefits when reducing feedback frequency or providing summary statistics. Therefore, novel AVB settings that are based on these concepts are developed and implemented. Method The underlying theoretical framework and resultant implementation of innovative AVB settings on a smartphone-based voice monitor are described. A clinical case study demonstrates the functionality of the new relative frequency feedback capabilities. Results With new technical capabilities, 2 aspects of feedback are directly modifiable for AVB: relative frequency and summary feedback. Although reduced-frequency AVB was associated with improved carryover of a therapeutic vocal behavior (i.e., reduced vocal intensity) in a patient post-excision of vocal fold nodules, causation cannot be assumed. Conclusions Timing and frequency of AVB schedules can be manipulated to empirically assess generalization of motor learning principles to vocal behavior modification and test the clinical effectiveness of AVB with various feedback schedules.

Vocal Fold Nodules

The vibration characteristics of the vocal folds are investigated using a finite element model which incorporates the in-homogeneity and anisotropy of the materials and the irregularity of the geometry. The model employs the cover and body theory to build the structure of the vocal folds and implements measured viscoelastic properties of the mucosa and the transverse isotropic elastic properties of the muscles. It has the potential to simulate some vocal-fold disorders and determine the change in characteristics. To determine the oscillation characteristics of the folds, the eigenfrequency and eigenmodes of the finite element model are determined using the ABAQUS software. The model results compare well with some experiments performed on a silicon vocal fold. It is anticipated that the model will help to identify voice disorders such as vocal-fold paralysis and vocal-fold nodules.
