Comparison of outcomes of the Epley and self-Epley maneuvers in PC-BPPV: A randomized controlled trial.

OBJECTIVES: This study aimed to compare the efficacy of the self-Epley and Epley maneuvers in treating posterior canal benign paroxysmal positional vertigo (PC-BPPV) in patients at the outpatient clinic at the Department of Otolaryngology, Faculty of Medicine, Vajira Hospital, Navamindradhiraj University, Bangkok, Thailand. METHODS: In this prospective, randomized, comparative study, patients with PC-BPPV were randomized to receive the self-Epley or Epley maneuver. The self-Epley maneuver group received illustrated instructions and a video of how to perform the self-Epley maneuver. They then performed the first self-Epley maneuver under supervision in the clinic. The efficacy of the treatment was evaluated with the Dix-Hallpike test at the 1-week follow-up visit. RESULTS: Sixty-four patients with PC-BPPV were enrolled, 32 patients were the self-Epley maneuver group and the other 32 patients were the Epley maneuver group. After 1 week, 29 of the 32 patients (90.62 %) in the self-Epley maneuver group were cured, while 28 of the 32 patients (87.5 %) in the Epley maneuver group were cured. The Kaplan-Meier survival estimates with a log-rank test for cumulative therapeutic effects at 1 week showed no statistically significant difference between the groups (P = 0.755). CONCLUSIONS: The twice-a-day self-Epley maneuver had a high success rate and could be used for patients who cannot reach a hospital or needs quarantine due to covid-19. For the self-Epley maneuver, adequate instruction is important to obtain a good result. LEVEL OF EVIDENCE: II.

A study on the IOS application "uHear" as a screening tool for hearing loss in Bangkok.

Objective: This study was designed to compare the results of hearing tests performed using the uHear application with those of standard audiometry in Thai people in Bangkok. Methods: From December 2018 to November 2019, a prospective observational study was conducted involving Thai participants aged between 18 and 80 years. All participants were tested using standard audiometry and the uHear application in a soundproof booth and in a typical hearing environment. Results: This study included 52 participants (12 males and 40 females). The Bland-Altman plot with the Minimal Clinical Meaningful Difference of 10 dB between standard audiometry and the uHear in a soundproof booth found agreement at 2000 Hz. The uHear in a soundproof booth showed high sensitivity at all frequencies (82.5%-98.9%) and high specificity at 500 and 1000 Hz (85.7%-100%). uHear in a typical hearing environment showed high sensitivity at 4000 and 6000 Hz (97.6%) and high specificity at 500 and 1000 Hz (100%). When considering the pure-tone average, uHear in a soundproof booth showed high sensitivity (94.7%) and specificity (90.7%), whereas, in a typical hearing environment, uHear showed poor sensitivity (34%) and high specificity (100%). Conclusion: uHear was accurate for hearing loss screening at 2000 Hz in a soundproof booth. However, uHear in a typical hearing environment lacked accuracy. The uHear application in a soundproof booth can be used to screen hearing loss in some situations where standard audiometry is impossible. Level of Evidence: II.

Impact of the COVID-19 pandemic on the otolaryngology residency training program in a university-based hospital in Bangkok, Thailand.

Objective: This study aimed to evaluate the impact of the COVID-19 pandemic on the otolaryngology residency training program in Vajira Hospital, Navamindradhiraj University. Methods: Conducted from October 2021 to January 2022, this cross-sectional survey included all residents, residents who graduated in 2021, and the attending staff. One form was sent to both resident groups for self-assessment and another form to the attending staff for resident assessment. The survey questions were about attitude toward COVID-19 service, knowledge, outpatient department service, surgical skills, and burnout assessment using the Maslach Burnout Inventory. Results: This study included 17 residents and 9 attending staff members. COVID-19 indeed had affected the clinical and surgical training. Regarding the attitude toward COVID-19 services, the residents were moderately satisfied. They were concerned about work suspension resulting from infection and also death from COVID-19. N95 masks and other protective gears were scarce. Compared with those during the prepandemic era, residents had fewer academic activities, and they preferred hybrid teaching. The inpatient department, outpatient department, and surgical training opportunities, as well as elective and urgent surgeries, were also reduced. The attending staff considered 1-year extension of the training program, but the residents disapproved. The residents became less confident both in outpatient department service and surgical skill, and they felt emotional exhaustion, depersonalization, and decreased sense of personal accomplishment. Conclusion: COVID-19 pandemic had significant impact on otolaryngology residency training programs. It did not only affect burnout among residents but also caused a perception of skill and knowledge reduction.
