Long-term neurosensory deficits following transoral vertical ramus and sagittal split osteotomies for mandibular prognathism☆

Twenty-six patients who had been treated for mandibular prognathism by either bilateral sagittal split osteotomy or transoral vertical ramus osteotomy were evaluated by neurosensory examination. Neuropathy was demonstrable in 28.8% of the 52 mental nerves examined. The incidence of neuropathy was significantly higher in the bilateral sagittal split osteotomy group than in the transoral vertical osteotomy group.

Mandibular interpositional and onlay bone grafting for treatment of mandibular bony deficiency in the edentulous patient

The development of interpositional and onlay bone grafting techniques for atrophic mandibles is reviewed. A further modification of the visor osteotomy is presented along with follow-up evaluation of the conditions of 16 patients. Results of radiographic measurements show the procedure to be stable, vertical resorption of the augmented mandible in the body regions being 11.2% over a mean follow-up of 8.8 months. Neurosensory evaluation showed altered sensation and dysesthesia as a significant problem in these patients. The results are presented and discussed.

Bone scanning with99mtechnetium phosphate to assess condylar hyperplasia. Report of two cases

Abstract Condylar hyperplasia poses a problem in planning treatment because it is a self-limiting process for some but not all patients. Continued growth creates a progressive deformity that requires condylectomy, whereas an enlarged condyle can be left in place after hyperplastic growth ceases, even if ramus surgery is needed to correct asymmetry. Bone scan with 99m technetium phosphate can be used to assist in making the differential diagnosis. In the two patients reported here, abnormal metabolic activity revealed by bone scans supported clinical and historical evidence that the condylar hyperplasia was active and required surgical correction, including condylectomy. The two cases demonstrate different approaches to postsurgical orthodontic treatment, depending on the amount of normal growth expected.

Squamous-cell carcinoma arising in a lateral periodontal cyst.

Abstract A rare case of well-differentiated squamous-cell carcinoma arising in the epithelial lining of a lateral periodontal cyst is reported. Submission of surgically removed tissues for histopathologic evaluation is emphasized. The surgical site has been reconstructed and functions well. Because of early diagnosis and treatment, the patient has no evidence of clinical disease 2 1 2 years postoperatively.

Self-stabilizing approach to surgical uprighting of the mandibular second molar

A technique for surgical uprighting of malposed mandibular second molars is described. The principal advantage of this technique is that the tooth is stabilized by bone on the distal aspect of the uprighted tooth. Long-term clinical and radiographic follow-up reveals positional stability and no adverse pulpal or periodontal sequellae.

Mandibular juvenile fibrous histiocytoma with ossification: A case report

Summary The surgical management of a rare tumor involving the mandible of a newborn is reported. The histological findings and literature are reviewed.

Skin graft vestibuloplasty exostosis: A report of two cases

Two cases of exostosis developing after mandibular vestibuloplasty and floor-to-mouth lowering with split thickness skin graft are presented, one with multiple recurrences. The lesion is clinically and microscopically described. Hypotheses with respect to the development of this phenomenon are proposed.
