Benign lesions of the vocal folds have various appearances. Histopathologic examination might provide the true diagnosis. Therefore, histologic slides of 74 patients (92 vocal folds) with clinically well-defined diagnoses were single-blind examined by a pathologist. Single histologic features did not differentiate between different clinical entities, but combinations make some diagnoses more likely than others. Ultrastructural examination of submucosal vessels in the three most common clinical entities (polyps, Reinke edema, and vocal fold nodules) showed an entity-unique pattern of abnormal increase of layers of basement membrane—like material. A potential pathogenetic model of benign lesions of the vocal folds is presented, employing a combination of histopathologic findings and their possible relations with various forms of trauma inducing and maintaining these lesions.

Objective measurements derived from digitized laryngeal stroboscopic images were used to demonstrate changes in vocal fold vibration and in the size of benign lesions after 3 months of voice therapy. Forty chronically dysphonic patients were studied. By means of a rigid stroboscope, pretreatment and posttreatment recordings were made of the vocal folds at rest and under stroboscopic light during phonation. From each recording, images of the positions at rest and during vibration at maximal opening and at maximal closure were digitized. The surface areas of any lesions and of the glottal gap were independently measured in the digitized images by 2 experienced laryngologists. Referential distances were determined in order to compensate for discrepancies in magnification in the various recordings. After 3 months of voice therapy, significant improvement in lesion size and degree of maximal closure during vibration could be demonstrated in about 50% of the patients. The degree of maximal opening did not prove to be a significant parameter.

Vocal Fold Surgery

In spite of the great significance of direct microlaryngeal surgery (DML), the inadequacies of this technique are evident. In order to avoid surgical trauma and introduce functional control during surgery, indirect microstroboscopic (IMS) and indirect videostroboscopic surgery (IVS) of the vocal folds are advocated. Both of these meet most criteria for surgical work in this field. The aim of this work was to make a comparative study of these techniques. The study is based on 603 operations conducted for benign lesions of the vocal folds. We are of the opinion that indirect vocal fold surgery for small benign lesions has significant advantages when compared with the conventional microlaryngoscopy, including laser surgery, which was proven elsewhere. When comparing these two indirect surgical approaches, the principal advantages of IVS surgery over the IMS method are easier surgical manipulation and better view. With respect to other areas of comparison, these techniques are quite similar. As complementary methods to conventional microlaryngoscopy, we believe that both IVS and IMS surgery should be used in practice.

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.

Vocal Fold Nodules

ABSTRACT Introduction Vocal nodules are known to be one of the most common benign lesions, commonly situated at the junction of anterior one third and posterior two third of vocal folds. Voice therapy is considered to be the gold standard of treatment of vocal fold nodule. Objectives To determine the efficacy of voice therapy in the treatment of vocal fold nodules and to identify any possible reason for failure to voice therapy in managing vocal fold nodules. Materials and methods A prospective study, conducted over a period of 6 months. Eighteen adult patients diagnosed with vocal fold nodules at a tertiary care hospital were subjected to 6 weeks of voice therapy. Pre and post therapy subjective (Voice Handicap Index-10) and objective (Rigid fiber optic laryngoscopy) evaluation was done. Patients with no improvement after 6 weeks of voice therapy underwent micro laryngeal surgery. All patients were followed up at 3 months and 6 months. Results In majority of patients, objective and subjective voice outcome parameters were significantly improved after voice therapy. Although a few cases showed no significant improvement after therapy, they recovered completely after microlaryngoscopic surgery. It was found that patients who required surgery even after voice therapy had hard nodules. How to cite this article Bakat B, Gupta A, Roy A, Roychoudhury A, Raychaudhuri BK.

AbstractA prospective study was designed to compare the effects on voice capacities after either suspension microlaryngoscopic surgery or indirect microlaryngostroboscopic surgery. Patients where the clinical diagnosis 'dysphonia due to a benign lesion of the vocal fold' was made, and who could be operated in either way, entered the study. Post-operative voice evaluation was performed on 21 patients after suspension microlaryngoscopic or indirect microlaryngostroboscopic surgery. The long-term voice results following indirect microlaryngostroboscopic surgery and suspension microlaryngoscopic surgery demonstrate a statistically significant improvement for the maximum intensity, maximum dynamic intensity range, dynamic intensity range at habitual speaking pitch, and melodic pitch range. In selected cases indirect microlaryngostroboscopic surgery offers a very good functional result.

Although commonly encountered in all human cultures, laughter remains poorly understood. In order to examine laryngeal function during laughter, telescopic and fiberscopic videolaryngoscopy was performed on five subjects, who laughed in the different vowels, at various frequencies, and in several voice qualities. During laughter, the vocal folds were found consistently to undergo rhythmic abduction and adduction. At the end of these specific phonation tasks, all subjects were able to gain voluntary control of paramedian vocal fold positioning. This study better defined laryngeal function during laughter. These results have important clinical implications. Voluntary vocal fold positioning has important applications in speech therapy for dysphonias, such as vocal fold nodules, in which the primary cause is vocal fold hyperadduction. Patients suffering from these hyperadductive dysphonias may be able to utilize laughter to correct them.

Objectives: Vocal fold nodules (VFN) are a bilateral epithelial thickening of the membranous vocal folds. In this study, children with VFN and their mothers took part in voice therapy. We then compared acoustic analyzes and subjective evaluations to those in previous literature to determine whether voice therapy is more effective for children with VFN when their mothers also take part in therapy. Methods: Children aged eight to 12 years who were diagnosed with bilateral VFN between January 2018 and January 2020 were included in this study. Participating children diagnosed with bilateral VFN were divided into two groups based on the wishes and cooperation of their families. Group 1 consisted of 16 patients; Group 2 included 17 patients. The children in Group 1 received voice therapy alone; children in Group 2 took part in therapy with their mothers. For all participants, the average fundemental frequency (F0), jitter percentages, shimmer percentages, maximum phonation time (MPT) and s/z ratios were measured. Pediatric voice handicap index (p-VHI) values were calculated as well. Results: The two groups’ measures pre-treatment and post-treatment were compared. Except for p-VHI, no significant difference was observed between the two groups. However, p-VHI post-treatment was significantly lower in Group 2 than in Group 1. Conclusions: Involving the families and even teachers of children with VFN in voice therapy can increase the effectiveness of therapy. The family’s involvement increases the child’s motivation in therapy. The mother’s presence during therapy, supporting the child or even doing the work with the child, can be a very important source of motivation for the child, who may already be tired from school and other activities. Thus, the mother’s involvement increases the child’s compliance with and interest in therapy.

Abstract Background Benign superficial lesions of vocal fold (nodule, polyp, cyst and Reinke's edema) arise from the epithelium and the lamina propria. Vocal abuse and misuse presumably lead to excessive mechanical stress and trauma in the membranous portion of vocal fold, resulting in wound formation. Wound healing leads to remodeling of the superficial layer of the lamina propria. This tissue remodeling leads to formation of benign vocal fold lesions. These lesions are classically treated by conventional microsurgery and recently by CO2 laser. The use of the CO2 laser for the surgical treatment of Minor Associated Pathological Lesions (MAPL's) is still controversial. Some preferred cold instruments, whereas others appreciate CO2 laser as a novel alternative to conventional microsurgery for benign vocal fold lesions. To summarize the reviewed literature the issue of CO2 laser versus cold instruments is still controversial and the stage is open for more studies. Aim The aim of this study is to investigate the effect of Co2 Laser versus cold instruments in the treatment of benign lesions of the vocal folds regarding voice outcome & vocal fold function. Methodology A meta-analysis study is done to assess the use of Co2 Laser versus conventional microlaryngeal surgery in treatment of vocal fold benign lesions. Results This study does not reveal any detectable differences in clinical outcomes in patients with nodules, polyps and cysts who underwent excision via CO2 laser or cold instruments. Conclusion There is no sufficient evidence to determine if conventional surgery or CO2 assisted surgery is better.

Vocal Fold Nodules

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.
