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.

SummaryA rare case of a schwannoma localized on the posterior pharyngeal wall is presented. It concerns a young man with an inflammatory ulcerated mass in the posterior wall of the pharynx causing severe difficulty in swallowing.Although schwannomas of the lateral pharyngeal wall are common, only one case located on the posterior wall has been described. The origin of these tumours at this particular site is thought to be the sympathetic nervous plexus of the posterior pharyngeal wall.In presenting our case, we comment on the origin of posterior pharyngeal wall schwannomas.

Twenty-two patients, with hypernasal speech and asymmetric velopharyngeal insufficiency (VPI) identified preoperatively by multi-view videofluoroscopy and nasopharyngoscopy, were managed with superiorly based pharyngeal flaps skewed to the side with reduced lateral pharyngeal wall movement. Patient age ranged from 5 to 58 years. The etiology of the VPI included cleft palate with or without cleft lip, neurogenic VPI, velocardiofacial syndrome, tumor resection or latrogenic causes, submucous cleft palate, neurofibromatosis, and hemifacial microsomia. Follow-up, at 1 year and thereafter, showed resolution of VPI in all but two patients. An auxiliary flap to augment the primary flap was added on the side of diminished lateral pharyngeal wall motion which corrected the residual VPI. Three patients developed hyponasality. One was a child whose symptoms improved with time and growth. Two were adults, but the hyponasal resonance was mild and required no further Intervention. The advantage of skewing flaps is that at least one port functions adequately for ease in respiration and for drainage of secretions, thus reducing the risk of nasal obstruction. One open port also allows access for nasoendotracheal intubation should anesthetic be required for future operations.

In assessing lateral pharyngeal wall movement during routine cinefluorographic examination for velopharyngeal adequacy, the inclusion of submentovertical projection is important to the lateral projection of the velum. The main structures of the nasopharynx and surrounding areas are defined, and a method to obtain visualization of this area in normal subjects is described. The degree of lateral pharyngeal wall movement varies among normal individuals and may affect the success of pharyngeal flap operations in patients with velopharyngeal inadequacy.

Anterior bulging of the posterior pharyngeal wall (PPW) and its contact with the base of the tongue (BOT) is an essential element of the pharyngeal stage of swallowing. Postoperative changes in the extent of anterior bulge of the PPW during the pharyngeal swallow were documented in 11 oral cancer patients who underwent surgical resections of the anterior tongue and/or floor of the mouth. Seven subjects demonstrated approximately a 30% or more increase in anterior bulge of the PPW during liquid and/or paste swallows at 3 months postoperatively relative to their preoperative values. The other four subjects demonstrated no change or a decrease in anterior bulge of the PPW postoperatively. No notable increase or decrease in anterior bulge of the PPW was observed between the 3- and 6-month postoperative evaluations of the six subjects whose 6-month post-operative data were available. PPW bulge tended to increase more in subjects with poor oropharyngeal swallow efficiency, which was likely to be related to greater extent of tongue resection. These results suggest the potential for compensatory movement of the PPW when the BOT is positioned more anteriorly, and a possible treatment approach to increasing PPW contraction in dysphagic individuals with reduced BOT-to-PPW contact during the pharyngeal swallow.

Effects of a tongue-holding maneuver on anterior bulging of the posterior pharyngeal wall (PPW) during swallowing were investigated in 10 young adult normal subjects. Videofluorographic images of 3-ml liquid barium swallows were digitized to quantify the extent of anterior bulge of the PPW with and without the maneuver at the mid and the inferior levels of the second cervical vertebra. A significant increase in PPW bulging was seen with the maneuver at both pharyngeal levels. These findings indicate potential for developing new treatment techniques to facilitate compensatory anterior movement of the PPW, which has not been a target for direct treatment in the past. At present, the tongue-holding maneuver can be employed clinically as an easy method for testing the compliance of the PPW videofluorographically. However, the use of the maneuver per se, which inhibits posterior retraction of the base of tongue (BOT), resulted in increasing the pharyngeal (specifically vallecular) residue after the swallow. The results also indicate the importance of tongue movement in triggering the pharyngeal swallow.

Movement of one lateral pharyngeal wall during the production of VCVCV trisyllables was monitored via pulsed ultrasound using a time-motion method of display. Three normal speakers produced the six English stop consonants* combined with five vowels. The extent of lateral pharyngeal wall movement was found to be greatest on low vowels and least on high vowels. Pharyngeal wall movement during consonant production appeared to be dependent on the adjacent vowels.
