Introduction :
The purpose of this study was to evaluate the cutoff point in PSG that will best identifying MBS and the correlation with the degree of mouth breathing with the severity of obstructive sleep apnoea symptoms (OSAS).
Objectives :
This study will be a retrospective review of the clinical information of non-obese paediatric patients suffering from OSA pre and post tonsillectomy& adenoidectomy Primary outcomes: - pre- and post-op apnea-hypopnea index (AHI) Secondary outcomes: - percentage of mouth breathing during total sleep time - questionnaire All nocturnal full PSG were performed by attended qualified sleep technologist in the Kwong Wah Hospital Paediatric Sleep Laboratory in Hong Kong from August 2011 to December 2018.To score mouth breathing events as increase amplitude from surrounding baseline in presence of nasal flow limitation during sleep. To score mouth breathing events as increase amplitude from surrounding baseline in presence of nasal flow limitation during sleep. The percentage of total mouth breathing time during sleep was sum up to calculate . An AHI>=1.5/h is considered statistically abnormal . In the current study, we used AHI >=1.5/h to define OSA.
Methodology :
Fifty-nine children were included in the analysis and 47 of the study group (79.7%) were male. The mean age at pre-operative PSG was 9.2+/-3.1 years. The mean AHI from 8.3+/-19.8 dropped to 4.1+/-11.6 (p< 0.001). Thirty-one (50.8%) were cured of OSA defined as AHI10.5% of %TST-MB have 4.2 times the odds for residual OSA than post-operative children with 10.5% of total sleep time with mouth breathing was found to have a high residual OSA. Tonsillectomy and adenoidectomy cannot cure OSA. In fact, mouth breathing should be treated as well in order to have an optimum effect.
Result & Outcome :
I DISAGREE to send the abstract to Continuous Quality Improvement Initiatives System (CQIs) for sharing after HA Convention.
