Objective: To determine the relationship between adenoidectomy and/or tonsillectomy in childhood and allergic diseases in adulthood. Materials and methods: A survey investigating the history of adenoidectomy and/or tonsillectomy was administered to patients that were followed-up by our department between January and June 2014 with the diagnosis of asthma, allergic rhinitis, urticaria-angioedema, drug allergy, food allergy, and venom allergy; patients willing to participate were included in the study. The relationship and risk ratios were analyzed. Results: Totally, 510 (female/male: 379/131) patients were included in the study: 248 with asthma, 205 with rhinitis, 82 with drug allergy, 73 with urticaria, 24 with food allergy, and 14 with venom allergy. Of these, 65 (12.7%) had undergone adenoidectomy and/or tonsillectomy. Of these 65 patients, 41 had asthma, 33 had allergic rhinitis, and 28 had other allergic diseases. No relation between the history of atopy and adenoidectomy and/or tonsillectomy (p=0.129) was detected; however, there was a positive correlation between asthma and patients aged <15 years having a history of tonsillectomy and/or adenoidectomy (p=0.020). The risk of asthma was determined to be increased by 1.96 fold among the patients, provided the patient had undergone adenoidectomy and/or tonsillectomy (confidence interval [CI]:1.14-3.36). No connection was observed between atopic and non-atopic asthmatic patients in relation to adenoidectomy and/or tonsillectomy (p=0.46). No relationship was observed between allergic rhinitis and adenoidectomy and/or tonsillectomy. Conclusion: Adenoidectomy and/or tonsillectomy in childhood increase the risk of asthma in adulthood, whereas it does not increase the risk of atopy. This result signifies the criticality of adenoidectomy or tonsillectomy in the pathogenesis of asthma
