OBJECTIVE: Recurrent acute rhinosinusitis (RARS) is defined as multiple episodes of acute rhinosinusitis in which the symptoms and signs of infection resolve completely between episodes. Limited data are available on the characteristics and preventive therapy of RARS. This study evaluated the clinical characteristics and predisposing factors of RARS in children as well as the preventive therapy. METHODS: Medical records of children with RARS diagnosed between January 2010 and December 2012 were obtained. Demographic data, presenting symptoms, predisposing factors and preventive therapy were reviewed. RESULTS: Ninety-four children with RARS were recruited. The mean age was 7.7±2.6 years, with a mean age of onset of 4.0±1.4 years. Sixty-one patients (64.9%) were boys and 56 patients (59.6%) had family history of atopy. The most common presenting symptom of RARS was purulent nasal discharge (100.0%), followed by nasal congestion (68.1%) and postnasal drainage (31.9%). The most common predisposing factor for RARS was immunoglobulin G subclass deficiency (78.7%), followed by non-allergic rhinitis (64.9%) and allergic rhinitis (35.1%). Sixty-five children (69.1%) received preventive therapy for RARS. The responses to preventive measures were: 80.0% (32/40 patients) to oral antibiotic prophylaxis, 50.0% (11/22 patients) to adenotonsillectomy, 91.7% (11/12 patients) to specific allergen immunotherapy, 27.3% (3/11 patients) to gentamicin nasal irrigation, and 66.7% (4/6 patients) to intravenous immunoglobulin. CONCLUSION: The most common presenting symptoms of RARS in children were purulent nasal discharge, nasal congestion and postnasal drainage. Children with RARS should be evaluated for the presence of underlying conditions such as immunodeficiency and allergic disease, which led to the appropriate management for these children.
