Purpose To advance our current knowledge of singer physiology by using ultrasonography in combination with acoustic measures to compare physiological differences between musical theater (MT) and opera (OP) singers under controlled phonation conditions. Primary objectives addressed in this study were (a) to determine if differences in hyolaryngeal and vocal fold contact dynamics occur between two professional voice populations (MT and OP) during singing tasks and (b) to determine if differences occur between MT and OP singers in oral configuration and associated acoustic resonance during singing tasks. Method Twenty-one singers (10 MT and 11 OP) were included. All participants were currently enrolled in a music program. Experimental procedures consisted of sustained phonation on the vowels /i/ and /ɑ/ during both a low-pitch task and a high-pitch task. Measures of hyolaryngeal elevation, tongue height, and tongue advancement were assessed using ultrasonography. Vocal fold contact dynamics were measured using electroglottography. Simultaneous acoustic recordings were obtained during all ultrasonography procedures for analysis of the first two formant frequencies. Results Significant oral configuration differences, reflected by measures of tongue height and tongue advancement, were seen between groups. Measures of acoustic resonance also showed significant differences between groups during specific tasks. Both singer groups significantly raised their hyoid position when singing high-pitched vowels, but hyoid elevation was not statistically different between groups. Likewise, vocal fold contact dynamics did not significantly differentiate the two singer groups. Conclusions These findings suggest that, under controlled phonation conditions, MT singers alter their oral configuration and achieve differing resultant formants as compared with OP singers. Because singers are at a high risk of developing a voice disorder, understanding how these two groups of singers adjust their vocal tract configuration during their specific singing genre may help to identify risky vocal behavior and provide a basis for prevention of voice disorders.

Voice Use

PurposeVocal fold motion impairment (VFMI) can be the result of iatrogenic or traumatic injury or may be idiopathic in nature. It can result in glottic incompetence leading to changes in vocal quality and ease. Associated voice complaints may include breathiness, roughness, diplophonia, reduced vocal intensity, feeling out of breath with talking, and vocal fatigue with voice use. A comprehensive interprofessional voice evaluation includes auditory-perceptual voice evaluation, laryngeal examination including videostroboscopy, acoustic and aerodynamic voice measures. These components provide valuable insight into laryngeal structure and function and individual voice use patterns and, in conjunction with stimulability testing, help identify candidacy for voice therapy and choice of therapeutic techniques.ConclusionA comprehensive, interprofessional evaluation of patients with VFMI is necessary to assess the role of voice therapy and develop a treatment plan. Although there is no efficacy data to support specific voice therapy techniques for treating VFMI, considerations for various techniques are provided.

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.
