[Adenotonsillectomy as a treatment modality for sleep disordered breathing in children: case report]. 
Children with sleep disordered breathing (SDB) can present with a range of symptoms, from simple snoring to obstructive sleep apnea (OSA) with secondary growth impairment, neurocognitive defects and sometimes cardiovascular sequelae that rearely lead to death.  The most common cause of SDB in children is adenoid and tonsillar hypertrophy.  The most common treatment for children with SDB not caused by malformations or illness is surgery, in the first place--adenotonsillectomy.  We are presenting the case of the 5-year-old boy with OSA in whom the recent diagnostic and therapeutic approach was performed, along with treatment outcome following the surgery and after the 6-month follow-up.
