Objectives This study aims to compare the efficacy of the Epley and Semont maneuvers in relieving posterior canal benign paroxysmal positional vertigo (BPPV) arising in the in patients at the Outpatient Department of the Department of Otolaryngology, Faculty of Medicine Vajira Hospital, Navamindradhiraj University, Bangkok, Thailand. Method In this prospective, randomized, comparative study, patients were assigned to receive one of the two treatment methods. First, BPPV was diagnosed with the Dix‐Hallpike test. Then, each patient was treated by either the Epley or Semont maneuver. Immediately afterward, the efficacy of treatments was evaluated with the Dix‐Hallpike test, and dizziness intensity was assessed with the visual analog scale (VAS). Results This study enrolled 80 patients with posterior canal BPPV, 40 of which underwent the Epley maneuver and the other 40 underwent the Semont maneuver. In the first week, The Epley maneuver cured 37 (92.5%) of the 40 patients, and the Semont maneuver cured 36 (90%) of the 40 patients. Statistical analysis revealed no significant difference in the efficacy of these treatments (P = .251). Regarding dizziness intensity, VAS scores decreased from 6.48 to 1.65 after the Epley maneuver and from 6.53 to 2.18 after the Semont maneuver. Statistical analysis revealed that the Epley maneuver was superior to the Semont maneuver (P = .009) in reducing dizziness intensity. Conclusions The Epley and Semont maneuvers had similar efficacy in curing posterior canal BPPV. Regarding the severity of dizziness after treatment, the Epley maneuver produced significantly better results than did the Semont maneuver. Level of Evidence: II

Objective The aim of this study was to evaluate the hearing outcome of cochlear implantation in patients deafened by Ménière’s disease. Study Design Retrospective single-institution study. Setting Tertiary medical center. Methods Our institutional database of 1400 patients with cochlear implants was reviewed to identify cases with deafness due to Ménière’s disease. Twenty-nine patients were identified: 24 with unilateral and 5 with sequential bilateral cochlear implants. Pre- and postoperative speech recognition scores and medical data were extracted from the medical record and analyzed. Results Overall the mean difference between pre- and postoperative speech recognition after >1 year was 56% (95% CI, 47.08%-64.92%). The mean preoperative monosyllabic word score was 9.5%, and the mean postoperative scores at 1 month, 3 months, 6 months, 1 year, and >1 year were 37.1%, 46.1%, 54.1%, 59.1%, and 66.8%, respectively. Cochlear implantation resulted in improved word scores in all patients regardless of prior medical or surgical treatment (endolymphatic sac, labyrinthectomy). The mean postoperative hearing improvement in patients aged <70 and ≥70 years was 65.26% (95% CI, 54.79%-75.73%) and 40.00% (95% CI, 27.22%-52.77%). Postoperative word scores in patients with bilateral cochlear implants were not significantly different between the first and second implanted ears or between the monoaural and binaural testing conditions. Conclusion Cochlear implant in patients deafened by Ménière’s disease significantly improves word recognition scores regardless of whether medical or surgical treatment is used prior to implantation. The potential improvement in word recognition scores decreases after age 70 years.
