Objectives Benign paroxysmal positional vertigo (BPPV) is the most common peripheral vestibular end‐organ disease. This article aims to summarize research findings and key discoveries of BPPV. The pathophysiology, diagnosis, nonsurgical, and surgical management are discussed. Methods A comprehensive review of the literature regarding BPPV up through June 2018 was performed. Results BPPV is typified by sudden, brief episodes of vertigo precipitated by specific head movements. While often self‐limited, BPPV can have a considerable impact on quality of life. The diagnosis can be established with a Dix‐Hallpike maneuver for the posterior and anterior canals, or supine roll test for the horizontal canal, and typically does not require additional ancillary testing. Understanding the pathophysiology of both canalithiasis and cupulolithiasis has allowed for the development of various repositioning techniques. Of these, the particle repositioning maneuver is an effective way to treat posterior canal BPPV, the most common variant. Options for operative intervention are available for intractable cases or patients with severe and frequent recurrences. Conclusions A diagnosis of BPPV can be made through clinical history along with diagnostic maneuvers. BPPV is generally amenable to in‐office repositioning techniques. For a small subset of patients with intractable BPPV, canal occlusion can be considered. Level of Evidence N/A
Objectives/Hypothesis Nasopharyngeal swabs currently remain the gold standard for COVID‐19 sample collection. A surge in testing volume has resulted in a large number of health care workers who are unfamiliar with nasal anatomy performing this test, which can lead to improper collection practices culminating in false‐negative results and complications. Therefore, we aimed to assess the accuracy and educational potential of a realistic 3D‐printed nasal swab simulator to expedite health care workers' skill acquisition. Study Design Prospective pre‐post interventional study. Methods A nasal swab task trainer (NSTT) was developed to scale from computed tomography data with a deviated septum. Frontline workers at COVID‐19 testing sites in Ontario, Canada, were recruited to use the NSTT for nasopharyngeal swab training. Integrated video recording capability allowed participants to self‐evaluate procedure accuracy. A five‐point Likert scale was collected regarding the NSTT's educational value and procedural fidelity. Results Sixty‐two frontline workers included in the study were primarily registered nurses (52%) or paramedics (16%). Following simulator use, self‐assessed accuracy improved in 77% of all participants and 100% of participants who expressed low confidence before training. Ninety‐four percent reported that the NSTT provided a complete educational experience, and 82% regarded the system as a more effective training approach than what is currently available. Eighty‐one indicated that the simulator should be used at all COVID‐19 testing sites, with 77% stating province‐wide implementation was warranted. Conclusions The nasal swab task trainer is an effective educational tool that appears well‐suited for improved skill acquisition in COVID‐19 testing and may be useful for training other nasal swab applications.

Background The aim of this study was to evaluate speech outcomes following surgical intervention for velopharyngeal dysfunction (VPD). Perceptual speech outcome data were subsequently analyzed in conjunction with patient factors such as congenital abnormalities, presence of cleft lip and/or palate, and age of repair. We hope to aid in the eventual creation of treatment algorithms for VPD, allowing practitioners to tailor surgical technique selection to patient factors. Methods A retrospective analysis was performed for all patients who underwent surgical correction of VPD at London Health Sciences Centre between the years 2005 and 2018. Two hundred and two consecutive VPD patients (median age 10.6 years) were followed for an average of 20.2 months after having undergone a superiorly based pharyngeal flap (121), Furlow palatoplasty (72), or sphincteroplasty (9). Speech outcomes were measured via the American Cleft Palate-Craniofacial Association (ACPA) perceptual speech assessment, and MacKay-Kummer Simplified Nasometric Assessment Procedures Revised (SNAP-R) was used to measure nasalence. Comparisons of mean preoperative and postoperative outcomes were made, as well as analyses regarding surgical procedure, syndrome, cleft status, and age. Results Mean perceptual scores improved significantly postoperatively (p < .0001), and successful perceptual resonance was identified in 86.1% patients (n = 174). Postoperative perceptual speech scores for three ACPA domains were superior with pharyngeal flap compared to both Furlow palatoplasty and sphincteroplasty ([hypernasality: p < .001, p < .02], [audible nasal emissions: p < .002, p < .05], [velopharyngeal function: p < .001, p < .05]). Success rate was higher in pharyngeal flap (94.2%) than in Furlow palatoplasty (75.0%, p < .001) or sphincter pharyngoplasty (66.7%, p < .001). No significant difference was identified in success rate based on syndrome or cleft status. Conclusion Operative management of VPD is highly effective in improving perceptual speech outcomes. Given proper patient selection, all three procedures are viable treatment options for VPD. For those patients identified as appropriate to undergo a pharyngeal flap, robust improvements in speech outcomes were observed. Graphical abstract
