Prior studies have used polysomnography to diagnose obstructive sleep apnea (OSA) and assess improvement post adenotonsillectomy (T&A).
We report 122 children who had severe OSA diagnosed by a McGill Oximetry Score (MOS) of 3 or 4. All children had T&A. Improvement was assessed by repeating the MOS. QoL was assessed using the OSA-18 questionnaire.
Changes in oximetry metrics documented fewer and less severe desaturation postoperatively;
- MOS decreased in 116 of 122 patients
Total OSA-18 score decreased in 115 of 122
Each OSA-18 item improved on average, the greatest improvements being in questions about sleep and breathing during sleep.
Of the patients that did not improve:
- 5 patients remained MOS 4;
- 6 patients had worsening of their OSA-18 scores;
- Predictors of non-improvement will be presented.
- MOS with clinical evaluation to decide upon T&A is reliable for MOS 3-4 patients.
- Certain OSA-18 items show more improvement after T&A.
- To describe the frequency and extent of QOL and oximetry improvements post T&A in children diagnosed with severe OSA using an oximetry/clinical based system.
- To understand which of the OSA-18 items typically improves postoperatively.
- To describe clinical, quality of life and oximetry factors that predict failure to improve after T&A.
