[Long term change in quality of life after adenotonsillectomy for pediatric obstructive sleep disorders].
BACKGROUND
To study short-term and long-term changes in quality of life (QOL) in children before and after adenotonsillectomy (T and A) for obstructive sleep disorders (OSDs).


METHODS
Prospective study of 20 children underwent T and A for OSDs at the University hospital of Ulm/Germany. Caregivers were asked to complete the Brouillette-Score (BS) and OSA-18 survey, validated instruments for detecting symptoms and QOL change in children with OSDs, at the initial office visit prior to surgery (BS/1 and OSA-18/1) within 7.5 +/- 1.14 weeks after surgery (BS/2 and OSA-18/2), and 14.8 +/- 1.98 months after surgery (BS/3 and OSA-18/3). The BS comprises 3 items including: difficulty breathing during sleep, apnea observed by the caregivers and snoring. The OSA-18 survey comprises 18 items in 5 domains of sleep disturbance, physical suffering, emotional distress, daytime problems, and caregiver concerns. Scores from the preoperative and postoperative surveys were compared using the paired T-test and SPEARMAN-RANK test.


RESULTS
13 children were male (65 %). The mean age at the time of inclusion in the study was 6.2 +/- 1.63 years, mean preoperative body mass index (BMI) was 17.4 +/- 1.24 kg/m(2). Brouillette-Score: The mean Brouillette-Score before T and A (2.72) was significantly higher ( P = or < .001) than in the short-term (- 2.19) and in the long-term. (- 3.54). OSA-18 SURVEY: The mean total score for OSA-18/1 (83.4) was significantly higher ( P = or < .001) than the mean total score for OSA-18/2 (29.8) and OSA-18/3 (25.6). The overall correlation between BS and OSA-18 was R = .887 ( P = or < .001).


CONCLUSIONS
Children with suspicious OSDs demonstrate significant short term and long-term improvement in the Brouillette-Score and OSA-18 survey. Caregivers perceive a long-term improvement for a minimum of one year in QOL after T and A for OSDs, although these improvements are not uniform across all domains of the OSA-18 survey. Use of the Brouillette-Score and the OSA-18 survey should decrease the need for polysomnographic monitoring and facilitate selection of children for T and A, whereas the OSA-18 questionnaire permits the more differentiated finding.
