The Results of Blowout Fracture in Patients under 18 Years of Age

Abstract

　　Young bone is elastic and is prone to greenstick fractures. We retrospectively evaluated 72 cases of fracture in patients younger than 18 years old. Examination items were compared among the following groups: baby (0-3 years old) , infant (4-6 years old) , elementary school lower grade (7-9 years old) , elementary school upper grade (10-12 years old) , junior high school student (13-15 years old) , and high school student (16-18 years old) . The number of cases increased with age, but the rate of surgery was unchanged (20-33%) . CT findings of inferior rectus muscle swelling or missing rectus sign may be good predictors of prolonged diplopia after surgical repair.
