Effectiveness and Safety of Prochlorperazine in Indian Patients with Acute Vertigo: Results from a Large, Prospective, Post-marketing Observational Study.

Aim: To assess the efficacy and safety of prochlorperazine in Indian patients with acute vertigo. Methods: In this prospective, multicenter, open-label, post-marketing observational study, patients with acute peripheral vertigo of different etiologies received 5 mg prochlorperazine thrice a day for 5 days. The primary endpoints were percentage of patients with improvement in (1) vertigo symptoms and (2) clinical response as per scale for vestibular vertigo severity level and clinical response evaluation (SVVSLCRE) from baseline to end of treatment (Day 6). The key secondary endpoints were (1) improvement in nystagmus grading, and (2) safety and tolerability Efficacy of prochlorperazine by route of administration of first prochlorperazine dose (oral or intramuscular) was also assessed. Results: Of 1716 enrolled patients (mean [standard deviation, SD]) age (42.0 [12.95] years; 53.6% men), 57.4% were diagnosed with Meniere's disease, followed by vestibular neuritis (17.4%), labyrinthitis (16.7%), or ear surgery (8.5%). In the overall population, 91.1% of patients showed improvement in clinical response per SVVSLCRE grading at Day 6 (p < 0.0001 vs. non-responders). Nystagmus grading was improved in 99.7% (of patients. No adverse drug reactions events were reported. Tolerability of prochlorperazine was rated as good, very good, and excellent by 43.6%, 32.9% and 20.7% of patients, respectively. Among patients with postoperative vertigo, 80.1% showed improvement in clinical response. In the intramuscular and oral subsets, 85.5% and 92.1% of patients showed improved clinical response, respectively. Conclusion: Prochlorperazine showed improvement in severity of symptoms and clinical response in all subsets of vertigo patients, with a good safety and tolerability profile.

Does nasal surgery improve multilevel surgical outcome in obstructive sleep apnea: A multicenter study on 735 patients.

OBJECTIVE: Does nasal surgery affect multilevel surgical success outcome. METHODS: Prospective eight country nonrandomized trial of 735 obstructive sleep apnea (OSA) patients, who had multilevel palate and/or tongue surgery, divided into two groups, with or without nose surgery. RESULTS: There were 575 patients in nose group, 160 patients in no nose group. The mean age for nose group 44.6 ± 11.4, no nose group 44.2 ± 11.8. Mean preoperative BMI for nose group 27.5 ± 3.6, no nose group 27.5 ± 4.1, mean postoperative BMI nose group 26.3 ± 3.7, no nose group 27.1 ± 3.8 (P = .006). Mean preoperative AHI nose group 32.7 ± 19.4, no nose group 34.3 ± 25.0 (P = .377); and mean postoperative AHI nose group 13.5 ± 10.2, no nose group 17.1 ± 16.0 (P = .001). Mean preoperative ESS nose group was 11.3 ± 4.7, no nose group was 10.4 ± 5.4 (P = .051); and mean postoperative ESS nose group was 5.3 ± 3.2, no nose group was 6.7 ± 2.8 (P = .001). The nose group had higher percentage change (adjusted for age, gender, BMI) in AHI (33.7%, 95% CI 14% to 53.5%) compared to the no nose group (P = .001); the nose group also had more percentage change in ESS (37%, 95% CI 23.6% to 50.3%) compared to the no nose group (P < .001). Change in BMI did not affect AHI nor ESS change (Cohen effect 0.03 and 0.14, respectively). AHI change in both groups were also statistically significant in the mild OSA (P = .008) and the severe OSA (P = .01). Success rate of surgery for the nose group 68.2%, while the no nose group 55.0% (P = .002). CONCLUSION: Combining nose surgery in multilevel surgery improves surgical success. LEVEL OF EVIDENCE: IIC.

Does drug-induced sleep endoscopy affect surgical outcome? A multicenter study of 326 obstructive sleep apnea patients.

OBJECTIVES/HYPOTHESIS: Our objective was to determine whether drug-induced sleep apnea (DISE) affects the successfulness of the surgical outcome. STUDY DESIGN: Prospective, seven-country, nonrandomized trial. METHODS: There were 326 consecutive obstructive sleep apnea (OSA) patients who had nose, palate, and/or tongue surgery included in the study. DISE was performed in only one group. RESULTS: There were 170 patients in the DISE group and 156 patients in no-DISE group. The mean preoperative body mass index (BMI) for the DISE group was 27.6 ± 4.6, whereas in the no-DISE group it was 28.1 ± 3.9 (P = .23). The mean preoperative systolic blood pressure (SBP) for the DISE group was 130.4 ± 16.7, whereas in the no-DISE group it was 142.9 ± 15.5 (P < .001). The mean preoperative diastolic blood pressure (DBP) for the DISE group was 81.4 ± 9.7, whereas in the no-DISE group it was 89.1 ± 9.7 (P < .001). The mean preoperative apnea-hypopnea index (AHI) for the DISE group was 32.6 ± 18.8, whereas in the no-DISE group it was 33.7 ± 19.6 (P = .61). The mean postoperative AHI for the DISE group was 15.9 ± 12.6, whereas in the no-DISE group it was 13.2 ± 8.8 (P = .023). The age-, gender-, BMI-adjusted percentage change in AHI for the DISE group was -48.4 ± 31.9, whereas in the no-DISE group it was -59.8 ± 18.6 (P < .001). The age-, gender-, and BMI-adjusted success rate for the DISE group was 66.5%, whereas in the no-DISE group it was 80.8% (P = .004). The age-, gender-, and BMI-adjusted change in SBP for the DISE group was -6.1 ± 8.6, whereas in the no-DISE group it was -13.3 ± 11.1 (P < .001). The age-, gender-, and BMI-adjusted change in DBP in the DISE group was -5.2 ± 12.1, whereas in the no-DISE group it was -12.4 ± 11.7 (P < .001). The mean age- and gender-adjusted change in BMI for the DISE group was -4.6 ± 12.9, whereas in the no-DISE group it was -6.3 ± 18.5 (P = .34). The Cohen effect of BMI on the overall AHI, lowest oxygen saturation, and blood pressure changes was 0.08. CONCLUSIONS: DISE may not significantly affect surgical success in OSA.

Long-term Complications of Palate Surgery: A Multicenter Study of 217 Patients.

OBJECTIVES/HYPOTHESIS: To investigate long-term complications of newer reconstructive palate surgery techniques. STUDY DESIGN: Retrospective case-series analysis. METHODS: Retrospective six-country clinical study of OSA patients who had nose and palate surgery. RESULTS: There were 217 patients, mean age = 43.9 ± 12.5 years, mean body mass index = 25.9 ± 4.7, mean preoperative apnea-hypopnea index [AHI] = 30.5 ± 19.1, follow-up 41.3 months. A total of 217 palatal procedures were performed, including 50 expansion sphincter pharyngoplasties (ESP), 34 functional expansion pharyngoplasties (FEP), 40 barbed reposition pharyngoplasties (BRP), 64 modified uvulopalatopharyngoplasties (mUPPP), 11 uvulopalatal flap procedures (UPF), nine suspension pharyngoplasties (SP), eight relocation pharyngoplasties (RP), and one z-pharyngoplasty (ZPP). Complications included were constant and/or felt twice per week; dry throat (7.8%), throat lump feeling (11.5%), throat phlegm (10.1%), throat scar feeling (3.7%), and difficulty swallowing (0.5%). Of the 17 patients who had a dry throat complaint, two were constant (one SP, one RP), 15 were occasional (10 mUPPP, three SP, two BRP). Of the 25 patients with the throat lump feeling, four were constant (three RP, one ZPP), 21 were occasional (10 mUPPP, five SP, five UPF, one BRP). Of the 22 patients with the throat phlegm feeling, four were constant (two SP, two RP), 18 were occasional (10 mUPPP, four BRP, two FEP, two SP). Of the eight patients with throat scar feeling, eight were occasional (four SP, two mUPPP, one FEP, one RP), none were constant. One patient had difficulty swallowing (RP procedure). There was no velopharyngeal incompetence, taste disturbance, nor voice change. Highest symptom complaints were mUPPP, SP, and RP, whereas the lowest symptom complaint was ESP. CONCLUSIONS: Newer palatal techniques have shown to have less long-term complications compared to the older ablative techniques. LEVEL OF EVIDENCE: 4 Laryngoscope, 130:2281-2284, 2020.
