The aim of this study is to classify the nasal bone fractures based on computed tomography (CT) analysis and patterns of the nasal bone fractures, and review 503 cases treated between 1998-2004 at the Department of Plastic Surgery, Inha University Hospital, Incheon, South Korea. The age, sex, etiology, associated injuries, pattern of fractures and treatments were reviewed and a radiographic study was analyzed. Plain simple radiographs of lateral and Waters view of the nasal bones combined with computed tomography scans were done. ⋯ Nasal reduction was carried out in average 6.5 days post the injury. The patterns of the nasal bones fractures classified by CT findings were type IIA (182 cases, 36%), IIBs (105 cases, 21%), IIB (90 cases, 18%), IIAs (66 cases, 13%), I (39 cases, 8%) and III (21 cases, 4.3%). We think the CT is necessary for diagnosing nasal bone fracture because the reliability of the plain film was only 82%.

Reconstruction of mandibular defects after tumor resection in infants is a particular challenge. Although autogenous rib grafts have no relevance nowadays for restoration of mandibular bone defects after ablative tumor surgery because of limited bone stock and the availability of other donor areas, they are a useful surgical alternative after tumor surgery in infants. We here report on a 6-month, 5-year, and 10-year follow-up of three children who were diagnosed with benign tumors of the mandible with osseous destruction at the ages of 4 months, 6 months, and 2 years, respectively. ⋯ Although further growth of rib grafts is difficult to predict and occlusal disharmony may occur because of physiologic maxillary growth and growth of the unaffected mandible, we think that autogenous rib grafts can be ideally used for restoration of mandibular continuity defects in newborns and young children. Clinical follow-up visits on a yearly basis and orthodontic controls are useful for early orthodontic treatment of growth deficits. Further corrective surgery with bone augmentation or osseous distraction is required after completion of growth of the facial skeleton.
