Abstract
OBJECTIVE: The purpose of this study was to review the clinical characteristics of the antrochoanal polyp (ACP) and to compare the differences between children and adults. PATIENTS AND METHODS: This study was performed in 56 patients who underwent endoscopic surgery for ACP between 2004 and 2014. The study population was subdivided into children (≤8 years old) and adults (>18 years old). Clinical findings of ACP, including symptoms, CT stages, and surgical outcomes were retrospectively analyzed. RESULTS: CT Stage II and III lesions were more common than CT stage I lesions in children (p<0.001). Accompanying maxillary sinus diseases were more common in adults (p<0.005). Purely endoscopic surgery for ACPs was performed in all children and 25 (86.2%) adults. The combined approach, endoscopic and canine fossa approach, was applied in 4 (13.8%) adults. The success rate was 88.9% in children and 93.1% in adults. According to the approach method, the success rate was 90.4% for the purely endoscopic approach and 100% for the combined approach. CONCLUSION: High incidence of CT stage II and III lesions in the child group with ACP in our study suggests that children with ACP present at a more advanced state because of late diagnosis. Accompanying maxillary sinus diseases can be present in patients with ACP, especially adults, which should be considered preoperatively and treated appropriately.
