Incidence of allergic rhinitis in children with residual snoring and sleep symptoms after adenotonsillectomy.

BACKGROUND AND OBJECTIVES:Allergic rhinitis may contribute to sleep disordered breathing (SDB) in children. Although adenotonsillectomy is commonly performed to treat SDB, some patients will return to their primary practitioners with residual sleep symptoms. The aim of this study was to assess the incidence of allergic rhinitis via radioallergosorbent testing (RAST) in children undergoing adenotonsillectomy who had residual snoring or sleep symptoms. METHOD:A retrospective analysis of 500 patients post-adenotonsillectomy was undertaken. The incidence of residual snoring, residual sleep symptoms and results of RAST, as well as total immunoglobulin E (IgE) after surgical intervention, were documented. RESULTS:Children with positive RAST results or elevated total IgE had a significantly greater incidence of residual snoring post-adenotonsillectomy (P = 0.049) and residual sleep symptoms after surgery (P <0.0001). DISCUSSION:A positive RAST or elevated IgE in children with SDB was associated with incomplete resolution of snoring and residual sleep symptoms after adenotonsillectomy. Thus, there should be raised suspicion of allergic rhinitis in this population.
