Purpose The purpose of this preliminary study was to identify a vocal task that could be used as a clinical indicator of the vocal aptitude or vocal fitness required for vocally demanding occupations in a manner similar to that of the anaerobic power tests commonly used in exercise science. Performance outcomes for vocal tasks that require rapid acceleration and high force production may be useful as an indirect indicator of muscle fiber complement and bioenergetic fitness of the larynx, an organ that is difficult to study directly. Method Sixteen women (age range: 19–24 years, M age = 22 years) were consented for participation and completed the following performance measures: forced vital capacity, three adapted vocal function tasks, and the horizontal sprint test. Results Using a within-participant correlational analyses, results indicated a positive relationship between the rate of the last second of a laryngeal diadochokinesis task that was produced at a high fundamental frequency/high sound level and anaerobic power. Forced vital capacity was not correlated with any of the vocal function tasks. Conclusions These preliminary results indicate that aspects of the laryngeal diadochokinesis task produced at a high fundamental frequency and high sound level may be useful as an ecologically valid measure of vocal power ability. Quantification of vocal power ability may be useful as a vocal fitness assessment or as an outcome measure for voice rehabilitation and habilitation for patients with vocally demanding jobs.

We aimed to determine the optimal management of recurrent laryngeal nerve (RLN) involvement in thyroid cancer. We enrolled 80 patients with unilateral RLN involvement in thyroid cancer between 2000 and 2016. Eleven patients with preoperatively functional vocal folds (VFs) underwent sharp tumor resection to preserve the RLN (shaving group). Thirty-three patients underwent RLN reconstruction with RLN resection (reconstruction group). We divided the reconstruction group into two subgroups based on preoperative VF mobility (normal-reconstruction and paralyzed-reconstruction subgroups). In the cases where RLN reconstruction was difficult, phonosurgeries including arytenoid adduction (AA), with or without thyroplasty type I, or nerve muscle pedicle implantation with AA were performed later (phonosurgery group). We evaluated and compared vocal function among the evaluated periods and different groups. Postoperative vocal function in the shaving and normal-reconstruction subgroups was favorable. There were no significant differences between the two groups. In the paralyzed-reconstruction and phonosurgery groups, postoperative vocal function was significantly improved, and vocal function in the paralyzed-reconstruction subgroup was significantly better than that in the phonosurgery group. For optimal management of unilateral RLN involvement in thyroid cancer, first, sharp dissection should be performed, and if this is impossible, a simultaneous RLN reconstruction procedure should be adopted whenever possible.

Outcomes Management

Phonomicrosurgery in performing artists has historically been approached with great trepidation, and vocal outcome data are sparse. The vocal liability of surgically disturbing the superficial lamina propria (SLP) and epithelium must be balanced with the inherent detrimental vocal effect of the lesion(s). A prospective investigation was performed on 185 performing artists who underwent phonomicrosurgical resection of 365 lesions: 201 nodules, 71 polyps, 66 varices and ectasias, 13 cysts, 8 keratotic lesions. 2 granulomas, 2 Reinke's edema, and 2 papillomas. Nearly all patients with SLP lesions reported improvement in their postsurgical vocal function. This subjective result was supported by objective acoustic and aerodynamic measures. All postsurgical objective vocal function measures fell within normal limits, including a few that displayed presurgical abnormalities. However, given the relative insensitivity of standard objective measures to assess higher-level vocal performance-related factors, it is even more noteworthy that 8 of 24 objective measures displayed statistically significant postsurgical improvements in vocal function. Such changes in objective measures mostly reflect overall enhancement in the efficiency of voice production. Phonomicrosurgical resection of vocal fold lesions in performing artists is enjoying an expanding role because of a variety of improvements in diagnostic assessment, surgical instrumentation and techniques, and specialized rehabilitation. Most of these lesions are the result of phonotrauma and arise within the SLP. Successful management depends on prudent patient selection and counseling, ultraprecise technique, and vigorous vocal rehabilitation. Furthermore, an understanding of the vocal function and dysfunction of this high-performance population provides all otolaryngologists who manage laryngeal problems with valuable information that they can extrapolate for use in their practices.

Objective: To compare vocal function between females with benign vocal fold lesions, and females with normal voices by use of electroglottograph (EGG), also in addition to determining which EGG parameters were significantly correlated with the perceptual degree of dysphonia. Material and Methods: EGG data were obtained from 32 females with benign vocal fold lesions and 32 females with normal voices. The EGG parameter values were analyzed from their productions of four sustained vowels (/a:/, /u:/, /i:/, and /æ:/). Results: The two perturbation measures of EGG signals, EGG-jitter and EGG-shimmer of females with benign vocal fold lesions were significantly higher than those of normal females at a p-value<0.01 for all four vowels. EGG-SDF0 of females with benign vocal fold lesions were significantly higher than those of normal females at a p-value<0.01 for /i:/, and /æ:/. EGG-F0 of females with benign vocal fold lesions were significantly lower than those of normal females at a p-value<0.01 for /u:/, /i:/, and /æ:/. The differences in contact quotient were non-significant on all four sustained vowels between the two groups. In addition, EGG-SDF0 was found to be significantly correlated with the perceptual degree of dysphonia for four sustained vowels. Conclusion: The results of this study showed the differences between vocal function of females with benign vocal lesions and females with normal voices, using EGG parameters. Furthermore, EGG-SDF0 could be used as an indicator for the degree of severity of dysphonia in females with benign vocal fold lesions.

Purpose Phonation threshold pressure and perceived phonatory effort were hypothesized to increase and upper airway temperature to decrease following exposure to cold and/or dry air. Greater changes were expected with mouth versus nose breathing. Method In a within-participant repeated measures design, 15 consented participants (7 men, 8 women) completed 20-min duration trials to allow for adequate thermal equilibration for both nose and mouth breathing in 5 different environments: 3 temperatures (°C) matched for relative humidity (% RH), cold (15 °C, 40% RH), thermally neutral (25 °C, 40% RH), and hot (35 °C, 40% RH); and 2 temperatures with variable relative humidity to match vapor pressure for the neutral environment (25 °C, 40% RH), cold (15 °C, 74% RH) and hot (35 °C, 23% RH). Following each equilibration trial, measures were taken in this order: upper airway temperature (transnasal thermistor probe), phonation threshold pressure, and perceived phonatory effort. Results Data were analyzed using repeated measures analysis of variance, and no significant differences were established. Conclusions The study hypotheses were not supported. Findings suggest that the upper airway is tightly regulated for temperature when challenged by a realistic range of temperature and relative humidity environments. This is the first study of its kind to include measurement of upper airway temperature in conjunction with measures of vocal function.
