RESUMO
OBJECTIVES/HYPOTHESIS: Voice quality has emerged as an additional long-term outcome measure for patients with a history of airway surgery. The goal of this study was to evaluate the impact of preoperative voice assessment on the surgical management of patients who required complex airway surgery. STUDY DESIGN: Retrospective case series. METHODS: We analyzed clinical data for all patients who underwent an airway reconstruction procedure from September 1, 2012 to September 1, 2017 and had a voice clinic evaluation prior to surgery at a tertiary-care pediatric hospital. Each participant underwent a full clinical voice evaluation that yielded acoustic, imaging, perceptual, and handicapping index data. RESULTS: Six hundred forty-three patients underwent 831 airway surgeries (laryngotracheoplasty, cricotracheal resection, slide tracheoplasty, laryngeal cleft repair). Ninety-one (14.2%) of the 643 patients underwent a formal voice clinic evaluation prior to airway surgery; 39/91 (42.9%) were female. The mean age was 10.4 years (95% confidence interval [CI]: 9.2-11.6) with 31/91 (32.9%) participants demonstrating vocal fold immobility and 33/91 (36.3%) vocal fold hypomobility. A voice clinic evaluation provided new information for 62/91 (68.1%) patients, mainly for laryngeal dynamic components (vocal fold motion, source of phonation, arytenoid prolapse) and confirmed suspected disorders for the remaining patients. The average baseline Pediatric Voice Handicap Index overall score was 38.9 (95% CI: 33.3-44.5), and the average overall severity rating of the Consensus Auditory-Perceptual Evaluation of Voice was 54 (95% CI: 45.2-62.8). A voice clinic evaluation influenced management of 56/91 (61.5%) patients either by modification of the surgical plan (26/56, 46%) and/or adjusting voice therapy (21/56, 37.5%). CONCLUSIONS: Voice evaluation prior to airway reconstruction provided key information that influenced the management for most of the patients. Formal voice evaluation should be considered prior to complex airway surgery. LEVEL OF EVIDENCE: 4 Laryngoscope, 128:2858-2863, 2018.

OBJECTIVES: The purpose of the current study was to determine whether or not presenting patients with a video model improves efficacy of the assessment as defined by efficiency and decreased variability in trials during the acoustic component of voice evaluations. METHODS: Twenty pediatric participants with a mean age of 7.6 years (SD = 1.50; range = 6-11 years), 32 college-age participants with a mean age of 21.32 years (SD = 1.61; range = 18-30 years), and 17 adult participants with a mean age of 54.29 years (SD = 2.78; range = 50-70 years) were included in the study and divided into experimental and control groups. The experimental group viewed a training video prior to receiving verbal instructions and performing acoustic assessment tasks, whereas the control group received verbal instruction only prior to completing the acoustic assessment. Primary measures included the number of clinician cues required and instructional time. Standard deviations of acoustic measurements (eg, minimum and maximum frequency) were also examined to determine effects on stability. RESULTS: Individuals in the experimental group required significantly less cues, P = 0.012, compared to the control group. Although some trends were observed in instructional time and stability of measurements, no significant differences were observed. CONCLUSIONS: The findings of this study may be useful for speech-language pathologists in regard to improving assessment of patients' voice disorders with the use of video modeling.

IMPORTANCE: Up to half of children have substantial dysphonia after airway reconstruction. Visual assessment of vocal function is valuable. Feasibility of flexible and rigid endoscopy has been reported; however, the clinical utility of stroboscopy has not been examined. Rating of vibratory characteristics, such as mucosal wave and amplitude of vibration, is essential for the development of interventions to improve voice outcomes. OBJECTIVE: To examine (1) clinicians' ratings of anatomical and physiological features in children following airway reconstruction on initial voice evaluation using videolaryngostroboscopy and (2) the relationship of age to the type of endoscopy used. DESIGN, SETTING, AND PARTICIPANTS: Retrospective medical record review of 32 patients aged 3 to 21 years evaluated for postairway reconstruction dysphonia between July 2011 and July 2012 at a quaternary care children's hospital. INTERVENTIONS: Clinical voice evaluation protocol including rigid and/or flexible endoscopy with stroboscopy. MAIN OUTCOMES AND MEASURES: Demographic and voice quality characteristics were collected. The ability to complete endoscopy and ratings of anatomical and/or physiological features were assessed by a consensus of 4 clinicians. A t test was used to determine whether age was a significant factor in successful completion of videolaryngostroboscopy. RESULTS: Of 31 children who underwent flexible videolaryngostroboscopy, 22 (71%) examinations were completed with a distal chip endoscope and 9 (29%) with a fiberoptic. Significant differences were found in age between children who completed the distal chip vs. fiberoptic examination (mean [SD], 7.3 [2.7] vs. 5.5 [6.2] years; P = .05). Rigid endoscopy was attempted for 14 (44%) of 32 patients; 9 examinations (64%) were successful. Significant differences were found in age between patients for whom a rigid endoscopy could be successfully completed vs. those for whom it was not (mean [SD], 12.9 [3.4] vs. 6.2 [2.1] years; P < .001). Eighteen (56%) were glottic phonators, 8 (25%) supraglottic, and 6 (19%) aphonic. Vibratory characteristics were visible in 10 of 37 examinations (27%); 6 (16%) had ratable characteristics. CONCLUSIONS AND RELEVANCE: Endoscopy can be successfully completed in most children who have undergone airway reconstruction, most often using a distal chip endoscope.We found that vibratory characteristics were often not assessed adequately using videolaryngostroboscopy. Further work identifying imaging modalities that better display vibratory characteristics, such as high-speed videoendoscopy, may provide new insight into vocal function and lead to a more thorough evaluation.

PURPOSE OF REVIEW: To investigate the status of the recent literature focused on studying the assessment and treatment of pediatric voice and airway disorders using both established and novel techniques. RECENT FINDINGS: Recent research regarding voice assessment and treatment reveals the use of systematic and innovative approaches when collecting instrumental and perceptual voice data. There are recent advancements in certain surgical interventions designed to minimize complications. Wider use of functional endoscopic imaging of the pediatric larynx is improving our understanding of childhood voice production and airway management. There is also an important emerging focus on quantifying the impact of having a childhood voice disorder through the use of new tools. Although there is an increase in pediatric voice and airway research, many studies tend to be entirely descriptive rather than quantitative. There continues to be little specific research that uses prospective, longer-term and formal voice outcomes before and after behavioral and surgical interventions. SUMMARY: Pediatric voice and airway disorders are an important childhood health problem. Voice assessment in children should include formal perceptual and instrumental evaluations, including sophisticated acoustic, aerodynamic and imaging modalities. The care of these children requires a collaborative approach that includes systematic and innovative treatment methods.

BACKGROUND: The effect of active workstation implementation on speech quality in a typical work setting remains unclear. PURPOSE: To assess differences between sitting, standing, and walking on energy expenditure and speech quality. METHODS: Twenty-two females and 9 males read silently, read aloud, and spoke spontaneously during 3 postural conditions: sitting, standing, and walking at 1.61 km/h. Oxygen consumption (VO2), blood pressure, and rating of perceived exertion (RPE) were obtained during each condition. Expert listeners, blinded to the purpose of the study and the protocol, assessed randomized samples of the participants' speech during reading and spontaneous speech tasks in 3 postural conditions. RESULTS: Standing elevated metabolic rate significantly over sitting (3.3 ± 0.7 vs. 3.6 ± 0.9 ml·kg-1·min-1). Walking at 1.6 km/h while performing the respective tasks resulted in VO2 values of 7.0 to 8.1 ml·kg-1·min-1. There was no significant difference in the average number of syllables included in each speech sample across the conditions. The occurrence of ungrammatical pauses was minimal and did not differ across the conditions. CONCLUSION: The significant elevation of metabolic rate in the absence of any deterioration in speech quality or RPE support the utility of using active work stations to increase physical activity (PA) in the work environment.

OBJECTIVE: The purpose of this study was to examine the feasibility of conducting aerodynamic and acoustic assessment in children following airway reconstruction. Underlying etiologies, co-morbidities and age related factors can present challenges for meaningful instrumental data collection in this population. METHODS: A chart review of 100 children who were seen for a complete voice evaluation at the Center for Pediatric Voice Disorders at the Cincinnati Children's Hospital Medical Center was conducted. Children who completed full or partial aerodynamic and acoustic protocols were identified. Data regarding the ability to participate in the assessment was tabulated, and vowel samples taken from the acoustic data were subjected to signal type classifications (e.g., Type I, II, III). RESULTS: Fifty-three children met the inclusion/exclusion criteria of the chart review. Of those children, 58% (n=31/53) were able to complete the full acoustic and aerodynamic protocols without any modification. In regards to the aerodynamic protocol alone, 64% (n=34/53) could complete protocol. In regards to the acoustic protocol alone, 75% (n=40/53) could complete the entire acoustic protocol without any modification. There were 32% (n=17) who provided a Type I acoustic signal which was appropriate for measurement of F(0). There was a significant correlation between age and ability to complete the protocol for both the aerodynamic (p=.007) and acoustic (p=.004) protocols. CONCLUSIONS: This study demonstrated that a majority of children were capable of completing aerodynamic and acoustic protocols. A significant proportion of children in this study had severe dysphonia, precluding the ability to extract fundamental frequency. Although aerodynamic and acoustic measures are feasible for many patients in this population, the severity of dysphonias observed in these patients causes the use of these measures to be limited in some cases for documenting behavioral and surgical outcomes measures.
