Prospective multicentre study on barbed reposition pharyngoplasty standing alone or as a part of multilevel surgery for sleep apnoea.

OBJECTIVES: The aim of this study was to demonstrate in a prospective multicentre study that Barbed Reposition Pharyngoplasty (BRP) procedure is safe and effective in management of obstructive sleep apnoea/hypopnea syndrome (OSAHS) patients. DESIGN: Prospective study. SETTING: Multicentre study. PARTICIPANTS: Patients suffering from obstructive sleep apnoea. MAIN OUTCOMES MEASURES: Values of postoperative apnoea-hypopnea index (AHI), oxygen desaturation index (ODI), epworth sleepiness scale (ESS). RESULTS: 111 Barbed Reposition Pharyngoplasty procedures standing alone or as a part of multilevel surgery for OSAHS, performed between January and September 2016, were analysed in 15 different centres. The average hospitalisation period was 2.5 ± 0.5 days. The mean patient age was 46.3 ± 10.5 years. The average body mass index at the time of the procedure was 27.9 ± 3.2, and the majority of the patients were men (83%). The mean preoperative and postoperative apnoea/hypopnea index was 33.4 ± 19.5 and 13.5 ± 10.3, respectively (P < .001). The mean preoperative and postoperative ESS score was 10.2 ± 4.5 and 6.1 ± 3.6, respectively (P < .001). The mean preoperative and postoperative ODI were 29.6 ± 20.7 and 12.7 ± 10.8, respectively (P < .001). CONCLUSIONS: Patients undergoing BRP standing alone or as part of a multilevel approach for the treatment of OSAHS have a reasonable expectation for success with minimal morbidity.

Nasopharyngeal bacterial flora before and after adenoidectomy.

Fifty patients (23 males and 27 females), with chronically hypertrophied and infected adenoids were subjected to adenoidectomy. Pre- and post-operative nasopharyngeal swabs were taken to study bacterial colonization of the nasopharynx both quantitatively and qualitatively. Twenty healthy controls were included in this study. The swabs were cultured on MacConkey's and Columbia blood agar plates. The rate of isolation of potentially pathogenic microorganisms decreased markedly following operation, while normal inhabitant organisms showed notable increase in their numbers post-operatively to reach a near normal level. It is concluded from this work that adenoidectomy produces a physiological effect on the nasopharyngeal microflora by conversion of an abnormal flora to a nearly normal one.
