title: [Obstructive sleep apnea in children with cerebral palsy].
abstract: To determine the etiology of obstructive sleep apnea (OSA) in children with cerebral palsy (CP), a survey using a questionnaire was conducted on parents of 233 CP children (1-5 years old, mean age: 2.7) and on those of 343 control children during a routine medical check-up at the age of three. The prevalence of habitual snoring and nasal obstruction was 63 and 20% in CP children, which were significantly higher than in control children. Sleep apnea episodes and stridor were noted in 19.7 and 15.4% of CP children. A screening sleep study was performed using Apnomonitor II and a pulseoximeter (Pulsox 5) in 48 CP children whose questionnaires revealed habitual snoring and sleep apnea, and it was found that 27 and 58% of the children had on apnea-hypopnea index (AHI) of greater than 5 and a low level of SaO2 (LSaO2) of less than 85%, respectively. When another 10 CP children visited our hospital for treatment of severe OSA, precise evaluations including pharyngeal pressure and fiberscopic examination during sleep as well as a sleep study using an inductive prezysmograph (Respigraph) were performed. Adenoid and/or tonsillar hypertrophy were noted in only 4 children, and the main cause of sleep apnea in the other 6 children was pharyngeal collapse at the lingual base. Their OSA was successfully treated by adenotonsillectomy in 2 children, adenotomy in 2 children, UPPP and lingualplasty in 1 child, tracheostomy in 2 children, and nasal CPAP in 1 child. Before treatment of OSA in CP children, precise evaluation is recommended in order to perform appropriate treatment.
