Background: Asthma is a common cause of wheezing episodes in children.
Objectives:The work aimed to evaluate adenoidectomy or adenotonsillectomy in children - having obstructive sleep apnea associated with bronchial asthma OSA- aged 3-5 years on the control of asthma
 Patients and Methods: This was a prospective interventional study. Fifty consecutive children, aged 3 to 5 years with recurrent wheezy chest associated with OSA caused by adenotonsillar diseases were recruited from the outpatient clinic or inpatient ward of the Allergy, Immunology and Rheumatology unit, Children's Hospital, Assiut University and from Otorhinolaryngology department, Assiut University Hospital.
Results: There was a significant improvement in the asthma control level during the follow-up of the patients after adenoidectomy or adenotonsillectomy. In the current study preoperatively, it was found that most male patients had uncontrolled symptoms while most female patients had partially controlled asthma with significant differences between both sexes.
  Conclusion: Adenotonsillectomy in children with obstructive sleep apnea associated with bronchial asthma may be helpful in controlling the asthma symptoms among those children
