Abstract

Introduction

Prior studies have used polysomnography to diagnose obstructive sleep apnea (OSA) and assess improvement post adenotonsillectomy (T&A).

 

Methods

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.

 

Results

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.

 

Conclusions

  • 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.

Learning Objectives

  1. 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.
  2. To understand which of the OSA-18 items typically improves postoperatively.
  3. To describe clinical, quality of life and oximetry factors that predict failure to improve after T&A.
