Exploration The Improvement Of Neurocognitive Function In Children With Obstructive Sleep Apnea Hypopnea Syndrome After Adenotonsillectomy

Objective To investigate the changes of neurocognitive function in children withobstructive sleep apnea hypopnea syndrome before and after Adenotonsillectomy.Methods Before surgery, sixty-five children with OSAHS underwent polysomno-graphy and a battery of neurocognitive tests containing C-WISC, C-WYCSI, CPT. Theywere followed up in six months post-operation,and they were compared with healthy childrenat the same age. The data were analyzed with special Statistical soft SPSS11.5.Resultsâ‘ The preschool study group were higher than children with OSAHS beforeT&A in the most of Chinese Wechsler Young Children Scale of Intelligence. The children ofthe preschool study group were lower than the healthy group in information and picturecompletion. Mean Verbal IQ(VIQ), Performance IQ(PIQ) and Full Scale IntelligenceQuotient(FIQ) for the children afer T&A were higher than those of the children before T&A.The postoperative children showed no difference compared with the healthy group in the threeparts.â‘¡There were significant differences between the pre-and postoperative prepubertalOSAHS children in the most of WISC-CR.The children afer suegery were lower than thehealthy group in information and charing record. VIQ, PIQ and FIQ for the children afer T&Awere significantly higher than those of the children before operation. There was no significantdifference in those between the healthy group and prepubertal group. There was significantlyhigher than the children before operation for child attenion test. The postoperative childrenshowed no difference compared with the healthy group.Conclusion Neurocognitive function is impaired in children with OSAHS. Mostfunctions improve to the level of the control group, indicating that the impaired neurocog- nitive functions are mostly reversible, so we should treat the children with OSAHS in earlyadenotonsillectomy.
