Retrospective analysis of surgically treated Le Fort fractures.

Craniofacial suspension, in conjunction with intermaxillary fixation (IMF), is the time-honored method of Le Fort fracture repair. However, several patients with maxillary fractures treated at the Medical Center Hospital of Vermont in Burlington by the oral surgery and otolaryngology services have been managed with IMF alone. Twenty-one of these patients were examined retrospectively through comprehensive dental and otolaryngologic clinical analyses. Traditional concerns for facial elongation and nonunion were among the key questions addressed by this study. There was no evidence of nonunion in any patient examined. A comparison of each patient's lateral cephalometric roentgenogram with computerized norms suggested that facial elongation did not occur when IMF alone was the principal method of repair.

Subcortical bone grafting for ridge augmentation.

A surgical technique for augmentation of the alveolar ridge, involving horizontal osteotomy in the anterior part of the mandible with insertion of an autogenous bone graft, was studied in monkeys. The technique of closure results in an immediate vestibuloplasty. Results of the study showed a significant improvement in alveolar ridge height with minimal resorptive changes during the experimental period of 50 weeks. The effect of stress on the graft site was not evaluated. However, it is hypothesized that this technique would result in less resorptive changes than in onlay bone grafts because of the subcortical placement of the autogenous bone.
