Our objective was to investigate the prevalence of sleep-disordered breathing (SDB) and obstructive sleep apnea syndrome (OSAS) in 3-11-year-old Turkish children. A cross-sectional study was conducted in Zonguldak, northwestern Turkey. Symptomatic children were identified by using a self-administered questionnaire and were classified into three groups: nonsnorers, occasional snorers, and habitual snorers. All habitual snoring children were invited to undergo polysomnography (PSG). Nine hundred fifty-four children (79.5%) were nonsnorers, 205 (17.2%) were occasional snorers, and 39 (3.3%) were habitual snorers. There was no significant relationship between gender and habitual snoring (male, 3.4%; female, 3.1%; P > 0.05; odds ratio (OR), 1.13; 95% confidence interval (CI), 0.59-2.14). There was a statistically significant relationship between habitual snoring and allergic rhinitis (OR, 4.23; 95% CI, 2.14-8.35). Four children who snored every night, and who had apnea spells and/or troubled sleep, underwent adenoidectomy and/or tonsillectomy before polysomnographic evaluation because of clinical detoriation. Twenty-eight of 39 children with habitual snoring participated in PSG evaluation. PSG revealed that 11 children (0.9% of the total population) had OSAS. When 4 operated children were added to these 28 children, we found the minimum prevalence of OSAS to be 1.3% in our study group. There was a significant correlation between OSAS and troubled sleeping (P <0.001; OR, 4.37; 95% CI, 1.33-14.3). We found the prevalence of habitual snoring to be 3.3% in Turkish children by using self-administered questionnaires. Allergic rhinitis was significantly correlated with habitual snoring. Minimum estimated prevalence of OSAS was found to be 1.3%.

Background/Aims: We aimed to determine the effects of adenoidectomy and/or tonsillectomy (AT) on cardiac functions in children with adenoid and/or tonsillary hypertrophy and obstructive sleep apnea syndrome (OSAS) by using echocardiography with tissue Doppler imaging facility (TDI). Methods: Twenty-nine children with adenoid and/or tonsillary hypertrophy and OSAS and 26 children with primary snoring entered the study. Cardiac functions were assessed by echocardiography with TDI in both groups. Tests were repeated in the OSAS group 6 months after treatment with AT. Results: Echocardiography showed a decrease in estimated pulmonary artery systolic pressure from 31 ± 4.2 to 13.1 ± 2.3 (p < 0.001). In TDI, tricuspid E_m and E_m/A_m increased from 11.0 ± 2.7 to 13.5 ± 2.7 cm/s (p < 0.001), and 1.46 ± 0.52 to 1.82 ± 0.53 (p = 0.004), respectively, following AT, indicating improvement in right ventricular diastolic dysfunction. Similarly, mitral E_m and E_m /A_m increased from 12.3 ± 2.1 to 16.3 ± 2.7 cm/s, and from 1.65 ± 0.51 to 2.30 ± 0.54, respectively (p < 0.001). There was no significant difference between postoperative values and control group values. Conclusion: TDI is a technique able to detect diastolic dysfunction unnoticeable by conventional echocardiography. Following AT, we observed improvement in both left and right ventricular diastolic functions using TDI.
