RESUMO
Purpose: This article describes the design and implementation of a web-based portal developed to provide supported home practice between weekly voice therapy sessions delivered through telehealth to children with voice disorders. This in-between care consisted of supported home practice that was remotely monitored by speech-language pathologists (SLPs). Methods: A web-based voice therapy portal (VTP) was developed as a platform so participants could complete voice therapy home practice by an interdisciplinary team of SLPs (specialized in pediatric voice therapy), telehealth specialists, biomedical informaticians, and interface designers. The VTP was subsequently field tested in a group of children with voice disorders, participating in a larger telehealth study. Results: Building the VTP for supported home practice for pediatric voice therapy was challenging, but successful. Key interactive features of the final site included 11 vocal hygiene questions, traditional voice therapy exercises grouped into levels, audio/visual voice therapy demonstrations, a store-and-retrieval system for voice samples, message/chat function, written guidelines for weekly therapy exercises, and questionnaires for parents to complete after each therapy session. Ten participants (9-14 years of age) diagnosed with a voice disorder were enrolled for eight weekly telehealth voice therapy sessions with follow-up in-between care provided using the VTP. Conclusion: The development and implementation of the VTP as a novel platform for the delivery of voice therapy home practice sessions were effective. We found that a versatile individual, who can work with all project staff (speak the language of both SLPs and information technologists), is essential to the development process. Once the website was established, participants and SLPs effectively utilized the web-based VTP. They found it feasible and useful for needed in-between care and reinforcement of therapeutic exercises.

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.

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.

OBJECTIVE: To evaluate the level of agreement between reflux area index scores, the reflux symptom index (RSI), and the reflux finding score (RFS). Inter- and intrarater reliability of the RFS was assessed. A criterion of pH 5 was used to evaluate its effects on agreement. STUDY DESIGN: Adult participants were enrolled in this prospective study. METHODS: Eighty-two participants (72 patients and 10 controls) completed the RSI, videoendoscopy, and 24-hour pH probe monitoring. The reflux area index for extraesophageal reflux (EER) events was calculated at pH 4 and 5. Two speech-language pathologists and one otolaryngologist independently rated 36 endoscopic examinations using the RFS through a web-based system. A repeated rating of six examinations was completed. RESULTS: Chi-square revealed poor agreement between the diagnostic tools, regardless of which pH criterion was used. Intraclass correlation coefficients revealed fair interrater reliability of the RFS and moderate intrarater reliability. Independent-sample t tests for the RFS and reflux area index (RAI) scores failed to identify patients from normal controls. CONCLUSIONS: The results of this study highlight the lack of agreement among the current available diagnostic tools for EER. Raters were not in agreement regarding the presence and severity of physical findings of EER. Results support the need for greater consensus among the clinical tools used in the diagnosis of EER. Physical rating scales may overidentify patients and would benefit from uniform scales and training. Assessing EER occurring at pH 5 may also yield important diagnostic information. Further research is needed to verify normative RAI cutpoints.

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.

Laryngotracheal stenosis is defined as a congenital or acquired narrowing of the airway. Congenital causes may include subglottic membranous or cartilaginous narrowing. Acquired causes may include trauma due to prolonged endotracheal or tracheal intubation or laryngotracheal injury. Although advances have been made over the past 30 years in reconstructive surgeries to improve airway patency in these patients, long-term laryngeal function for voice production is not well defined in this population. This review examines causes, symptoms and signs, and methods for diagnosing laryngotracheal stenosis. Surgical management procedures are briefly summarized. The current literature on voice outcomes is summarized. The predominant voice characteristics in the population are presented, although results are challenged by the heterogeneity of voice presentation and paucity of data from instrumental measures. Considerations for subjective and instrumental assessment, measures of quality of life, instrumental methods, and treatment options specific to the needs of this population are discussed. Research strategies to identify long-term outcomes of surgical and behavioral treatments in this population are posed.
