Objective Surgical treatment of velopharyngeal insufficiency (VPI) includes a wide array of procedures. The purpose of this study was to develop a classification for VPI procedures and to describe variations in how they are performed. Design/participants/setting/outcomes: We completed an in-depth review of the literature to develop a preliminary schema that encompassed existing VPI procedures. Forty-one cleft surgeons from twelve hospitals across the USA and Canada reviewed the schema and either confirmed that it encompassed all VPI procedures they performed or requested additions. Two surgeons then observed the conduct of the procedures by surgeons at each hospital. Standardized reports were completed with each visit to further explore the literature, refine the schema, and delineate the common and unique aspects of each surgeon's technique. Results Procedures were divided into three groups: palate-based surgery; pharynx-based surgery; and augmentation. Palate-based operations included straight line mucosal incision with intravelar veloplasty, double-opposing Z-plasty, and palate lengthening with buccal myomucosal flaps. Many surgeons blended maneuvers from these three techniques, so a more descriptive schema was developed classifying the maneuvers employed on the oral mucosa, nasal mucosa, and muscle. Pharynx-based surgery included pharyngeal flap and sphincter pharyngoplasty, with variations in design for each. Augmentation procedures included palate and posterior wall augmentation. Conclusions A comprehensive schema for VPI procedures was developed incorporating intentional adaptations in technique. There was substantial variation amongst surgeons in how each procedure was performed. The schema may enable more specific evaluations of surgical outcomes and exploration of the mechanisms through which these procedures improve speech.

ObjectiveAssess 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 DesignProspective study.SettingMulti‐institutional.MethodsSixteen 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.ResultsReliability 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).ConclusionExposure 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.
