This study was conducted on 90 children with chronic tonsillitis and adenoid hypertrophy scheduled to undergo adenotonsillectomy. They were divided into 3 groups. Group 1(30 cases): those without any chest diseases and normal BHR. Group Il (30 cases): those with only increase in their bronchial hyperreactivity (BUR). Group III (30 cases): included children with bronchial asthma. All cases were subjected to ventilatory function tests, bronchial provocation •tests using methacholine, estimation • of the total blood eosinophilic count and total serum immunoglobuline E. These tests were done before and 3 months after adenotonsillectomy. There was a significant increase in the ventilatory function parameters in groups II and Ill after surgery. The PD20 significantly increased and the blood eosinophilic count and total serum IgE significantly decreased in groups 11 and III after adenotonsillectomy. Conclusion: Adenotonsillectomy for chronic tonsillitis and adenoid hypertrophy usually improves the ventilatory functions and BHR in asthmatic and non asthmatic children.
