Abstract:
The exact mechanisms of Adenoid hypertrophy (AHT) pathogenesis and otitis media with effusion (OME) are unclear but there is increasing evidence that allergies may play a role. We aimed to investigate the prevalence of atopy and the effect of anti-allergic drugs in patients with AHT and OME. In a non-randomized, prospective cross-sectional study, 122 patients younger than 18 years of age with AHT or OME were included. Atopic patients based on clinical symptoms of allergic disorders and/or elevated levels of total serum immunoglobulin E (IgE) were referred to allergists and tested for allergen sensitization by skin prick test (SPT). Atopic patients were treated with nasal corticosteroids and antihistamines. Response to treatment was evaluated by comparing symptoms score before and after the treatment. In this study 122 patients were evaluated, 116 of them had AHT and 30 patients had OME. The mean age of participants was 6.7±2.4 years old and 68 of them (55.7%) were male. Allergic symptoms were observed in 38 patients with AHT (32.7%) and nine patients with OME (30%). Among the total cases, 34 patients (28%) were considered atopic. SPT was performed on 25 (73%) cases of atopic patients, with 11 (44 %) positive results. The mean symptom score of AHT and OME decreased significantly after treatment respectively, (p=0.001, p=0.007). According to this study, atopy was relatively common in patients with AHT and OME. Treatment with nasal corticosteroid and antihistamines were effective in these patients.

Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:
Allergic Reactions
Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
