RESUMEN
OBJECTIVE To investigate the incidence rate of nasal septum fracture and it's influence on the effect of nasal bone reduction. METHODS Retrospective analysis of 212 cases of nasal fracture compared with nasal septum deviation were carried out. Among these cases 112 treated with nasal bone reduction only was called group A; the other cases were treated with nasal reduction concomitantly with septoplasty. Among them 58 cases were diagnosed with nasal septum fracture, it was called group B; 42 cases were diagnosed with nasal septum deviation, it was called group C. The postoperative nasal deformity rate was assessed, and the intraoperative findings of nasal septum contrast with preoperative CT diagnosis was analysed. RESULTS Three months after the operation, 27 cases (24.1%) of nasal deformity were found in group A; 9(9.0%) cases of nasal deformity were found in group B+C; septum fracture was found in 58 cases (100%) in group B and 30(71.8%) cases in group C introperatively. The diagnosis rate of nasal septum fracture by CT was 58.0%, while it's incidence rate was 88.0%. CONCLUSION More nasal septum fractures were observed introperatively than CT findings, and septoplasty concomitantly with nasal bone reduction can obviously reduce the rate of nasal deformity.
RESUMEN
OBJECTIVE@#To report the experience of canalplasty in treatment of stenosis or atresia of the external auditory canal.@*METHOD@#A retrospective review was performed on 10 patients (10 ears) that underwent canalplasty. The lesions located in bony segment in 1 case, cartilaginous segment in 3 cases, both in cartilaginous and bony segments in 6 cases, in which 4 cases accompanied with the middle ear diseases. All patients received the canalplasty surgery, and tympanoplasty was applied simultaneously if the patient had otitis media.@*RESULT@#Follow-up was conducted for 8-50 months respectively, 8 of the external auditory canal was wide and tympanic membrane gained a good shape, 2 case had stenosis or atresia reoccurrence after the operation.@*CONCLUSION@#Appropriate approach and elimination of the lesions thoroughly are key points for the canalplasty.
