Background & Objectives: Adenotonsillar hypertrophy is one of the leading causes in pediatric obstructive sleep apnea syndrome. Because untreated obstructive sleep apnea syndrome in children is associated with various complications such as neurobehavioral and cardiovascular dysfunction, it is very important to exactly diagnose and properly treat those patients. This study evaluates the effectiveness of adenotonsillectomy by assessing polysomnographic indices in pediatric obstructive sleep apnea syndrome.
Subjects & Methods: We evaluated children aged 4 through 15 years old (mean age=8.14 years old), a total 19 (Male=11, Female=8) with obstructive sleep apnea syndrome using the laboratory based polysomnography before and after adenotonsillectomy.
Results: After surgical managements, such as adenoidectomy or adenotonsillectomy, 89% of pediatric obstructive sleep apnea syndrome were successfully treated. The apnea-hypopnea index (from 10.76/hour to 0.78/hour, p=0.001), apnea index (from 5.64/hour to 0.54/hour, p=0.027), snoring (from 27.74% to 5.71%, p=0.002), arousal index (from 21.31/hour to 9.43/hour, p=0.001), minimal SaO2 (from 83.53% to 92.47%, p=0.017) were improved significantly following surgery.
Conclusion: In children with obstructive sleep apnea syndrome, we identified that various polysomnographic indices were significantly improved after surgical treatments.
