Multicenter Interrater Reliability in the Endoscopic Assessment of Velopharyngeal Function Using a Video Instruction Tool.

OBJECTIVE: Assess interrater agreement of endoscopic assessment of velopharyngeal (VP) function before and after viewing the video instruction tool (VIT). We hypothesized improvement in interrater agreement using the Golding-Kushner scale (GKS) after viewing the VIT. STUDY DESIGN: Prospective study. SETTING: Multi-institutional. METHODS: Sixteen fellowship-trained pediatric otolaryngologists who treat velopharyngeal insufficiency (VPI) rated 50 video segments using the GKS before and after watching the VIT. Raters assessed gap size percentage and lateral pharyngeal wall (LPW), soft palate (SP), and posterior pharyngeal wall (PPW) movement. Intraclass correlation coefficient was estimated for these continuous measures. Raters also indicated the presence of a palatal notch, Passavant's ridge, and aberrant pulsations (categorical variables). Fleiss κ coefficient was used for categorical variables. Wilcoxon signed-rank test was performed on the difference between the pre/post individual video ratings. RESULTS: Reliability improved for all continuous variables after watching the instructional video. The improvement was significant for PPW (0.22-0.30, P < .001), SP (left: 0.63-0.68, P < .001 and right: 0.64-0.68, P = .001), and LPW (left: 0.49-0.54, P = .01 and right: 0.49-0.54, P = .09) but not significant for gap size (0.65-0.69, P = .36). Among categorical variables, agreement on Passavant's ridge significantly improved (0.30-0.36, P = .03). CONCLUSION: Exposure to a video instruction tool improves interrater agreement of endoscopic assessment of VP function. Significant improvement was observed in our primary end points, specifically posterior pharyngeal wall movement, soft palate movement, and lateral pharyngeal wall movement. There was less impact of the VIT on the interrater agreement of the categorical variables, palatal notch, Passavant's ridge, and aberrant pulsations.

Multicenter interrater and intrarater reliability in the endoscopic evaluation of velopharyngeal insufficiency.

OBJECTIVE: To explore interrater and intrarater reliability (R (inter) and R (intra), respectively) of a standardized scale applied to nasoendoscopic assessment of velopharyngeal (VP) function, across multiple centers. DESIGN: Multicenter blinded R (inter) and R (intra) study. SETTING: Eight academic tertiary care centers. PARTICIPANTS: Sixteen otolaryngologists from 8 centers. MAIN OUTCOME MEASURES: Raters estimated lateral pharyngeal and palatal movement on nasoendoscopic tapes from 50 different patients. Raters were asked to (1) estimate gap size during phonation and (2) note the presence of the Passavant ridge, a midline palatal notch on the nasal surface of the soft palate, and aberrant pulsations. Primary outcome measures were R (inter) and R (intra) coefficients for estimated gap size, lateral wall, and palatal movement; kappa coefficients for the Passavant ridge, a midline palatal notch on the nasal soft palate, and aberrant pulsations were also calculated. RESULTS: The R (inter) coefficients were 0.63 for estimated gap size, 0.41 for lateral wall movement, and 0.43 for palate movement; corresponding R (intra) coefficients were 0.86, 0.79, and 0.83, respectively. Interrater kappa values for qualitative features were 0.10 for the Passavant ridge; 0.48 for a notch on the nasal surface of the soft palate, 0.56 for aberrant pulsations, and 0.39 for estimation of gap size. CONCLUSIONS: In these data, there was good R (intra) and fair R (inter) when using the Golding-Kushner scale for rating VP function based on nasoendoscopy. Estimates of VP gap size demonstrate higher reliability coefficients than total lateral wall, mean palate estimates, and categorical estimate of gap size. The reliability of rating qualitative characteristics (ie, the presence of the Passavant ridge, aberrant pulsations, and notch on the nasal surface of the soft palate) is variable.

Quality of life in children with velopharyngeal insufficiency.

OBJECTIVE: To determine if quality of life (QOL) is affected in children with velopharyngeal insufficiency (VPI). DESIGN: Interview and survey. SETTING: Two university pediatric ambulatory centers. PARTICIPANTS: This population-based sample included 58 children, aged 5 to 17 years, and their parents; 29 of the children were diagnosed as having VPI and 29 were age-matched normal controls. INTERVENTION: Each participant (child and parent) completed 2 questionnaires: the Velopharyngeal Insufficiency Quality of Life (VPIQL), an instrument specifically designed for children with VPI, and the Pediatric Quality of Life Inventory, version 4.0 (PedsQL(4.0)), a standardized generic assessment instrument that systematically assesses the perception of health-related QOL in pediatric patients with chronic health conditions. MAIN OUTCOME MEASURES: The VPIQL questionnaire assessed patients' and parents' perceptions of speech, swallowing, situational and emotional difficulty, activity limitations, and perception of the patient by others. Caregiver impact was also assessed in the parent version of the VPIQL. RESULTS: The patients with VPI and their parents perceived a more statistically significant negative QOL compared with the normal controls and their parents in all domains of the VPIQL and the PedsQL(4.0). The parents of the children with VPI perceived a more negative emotional impact (P = .02), greater speech limitations (P = .05), and fewer swallowing problems (P<.001) compared with their children. CONCLUSIONS: Children with VPI and their parents perceive negative QOL greater than that of normal controls and their parents. Parental proxy may be an adequate substitute in this population.

Major aorto-pulmonary collateral arteries (MAPCAs)--Bronchial fistula presenting as tracheotomy bleed.

Tracheal hemorrhage is a common occurrence in pediatric patients with long-term tracheotomies. The majority of these events are related to self-limited etiologies, such as granulation tissue or suction trauma. Tracheo-arterial fistula, however, represents a frequently fatal form of tracheal hemorrhage that may initially be difficult to distinguish from other causes. Previous reports have described the pathophysiology, presentation and management of tracheo-arterial fistula involving the innominate artery. We describe a case of a 21-month-old male with a history of significant congenital cardiac malformations and chronic tracheotomy tube dependence who presented with intermittent, brisk bleeding from the tracheotomy tube. He was ultimately diagnosed with and treated for an arterio-bronchial fistula from a major aorto-pulmonary collateral artery. We review the etiology and management of this disorder.

Impact of adenotonsillectomy on quality of life in children with obstructive sleep disorders.

OBJECTIVES: To determine the impact of adenotonsillectomy on quality of life (QOL) in children with obstructive sleep disorders (OSDs) before and after surgery. DESIGN: Prospective, observational, before-and-after trial. SETTING: Seven tertiary pediatric otolaryngology practices. PATIENTS: Convenience sample of 101 children (mean age, 6.2 years) with adenotonsillar hypertrophy and OSD scheduled for adenotonsillectomy. INTERVENTION: Adenotonsillectomy was performed in children for OSDs. Quality of life was assessed using the Obstructive Sleep Disorders-6 survey, a validated instrument for detecting QOL change in children with OSDs. Surveys were completed at the initial office visit (visit 1), the day of surgery (visit 2), and at the postoperative office visit (visit 3). Physical characteristics were assessed using tonsillar and orocraniofacial scales (visit 1). Satisfaction with health care decisions was assessed using the Satisfaction With Decision and Satisfaction With Office Visit scales (visit 1). MAIN OUTCOME MEASURES: Short-term changes in QOL before (visits 1 and 2) and after (visits 2 and 3) surgery. RESULTS: Changes in QOL before surgery were trivial or small, and smaller than changes after surgery (mean change score, 0.18 vs 2.3; P<.001). Large, moderate, and small improvements in QOL were seen in 74.5%, 6.1%, and 7.1% of children, respectively. Sleep disturbance, caregiver concern, and physical suffering were the most improved domains, although significant changes also occurred for speech and swallowing problems, emotional disturbance, and activity limitations. Five percent of children had poorer QOL after surgery, but no predictive factors were identified. CONCLUSION: Adenotonsillectomy produces large improvements in at least short-term QOL in most children with OSDs.
