RESUMO
Objective@#To investigate the treatment results of occlusal disorder caused by old mid-facial fracture.@*Methods@#A total of 299 patients aged 26-51 years were enrolled in this study. All cases experienced a delay of treatment over 4 weeks after injury. The old mid-facial fracture was scanned by spiral CT and model surgery conducted. Ostectomy and rigid internal fixation were performed.@*Results@#The wound was healed by first intention without infection and other complications. After 1-24 months of follow-up, 299 patients achieved well-shaped mid-face and the occlusion was recovered with mouth opening of over 2 cm.@*Conclusions@#Model surgery combined with ostectomy and rigid internal fixation can achieve satisfied treatment results in patients with old mid-facial fractures.
RESUMO
Objective:To evaluate the changes of maxillary sinus density after mid-facial fractures.Methods: A retrospective review was performed on patients with mid-facial fractures from 1995 to 2006.The changes of maxillary sinus density were evaluated by Water's view.Results: There were 219 cases,including 165 male and 54 female patients,who showed changes of maxillary sinus density on Water's view.Their ages ranged from 3 to 78 years.78 cases had follow-up plain radiograph.Among them,51 cases had normal maxillary sinus density,the density of sinuses of 19 cases became lower and the density of sinuses of 8 cases did not change or became higher.Conclusion: The maxillary sinusitis is a late complication and develops in some maxillary sinus after treatment of mid-facial fractures.Attention to the maxillary sinus density should be paied when following-up.
