Objectives: It is well known that allergic rhinitis (AR) has positive association with adenotonsillectomy. However, the impact of AR on symptom improvement after adenotonsillectomy is not well documented. Hence, we aimed to evaluate the effect of AR on the symptom improvement after adenotonsillectomy between AR and nonallergic patients.
Methods: A retrospective analysis was performed on 250 pediatric patients younger than 10 years old who received adenotonsillectomy from June 2009 to June 2014 in a tertiary referral hospital. All patients underwent skin prick test or multiple allergen simultaneous test (MAST) before surgery and classified into AR group and control group. Obstructive and rhinitis symptoms including snoring, mouth breathing, nasal obstruction, rhinorrhea, itching, and sneezing were evaluated before and 1 year after surgery using questionnaire and telephone survey.
Results: AR group was 131 and control group was 119, showing higher prevalence (52.4%) of AR among adenotonsillectomized patients. Both groups showed dramatic improvement of symptoms such as snoring and mouth breathing after surgery (all P<0.05). However, AR group showed significantly less improvement than control group in snoring, mouth breathing, nasal obstruction, and rhinorrhea (all P<0.05). Multivariate analysis showed that preoperative mouth breathing and snoring were dependent on tonsil grade and postoperative symptoms were mainly dependent on presence of AR. Nasal obstruction was dependent on tonsil grade and presence of AR preoperatively and presence of AR postoperatively. These suggest the importance of AR as a risk factor for mouth breathing, snoring, and nasal obstruction.
Conclusion: AR has positive association with adenotonsillectomy and not only allergic symptoms but also obstructive symptoms such as snoring and mouth breathing improved less in AR group than control group. Hence, patients with AR should be monitored for long-term basis and more carefully after adenotonsillectomy.
