Esophageal adenocarcinoma metastatic to the maxilla.

Although metastatic malignant lesions in the maxilla are exceedingly rare, case reports of such lesions do appear occasionally in the literature. This article describes the clinical and pathologic features of an esophageal adenocarcinoma metastatic to the maxilla. The initial maxillary appearance of the tumor mimicked primary dental pathosis and, in addition, was the presenting sign of malignant disease in the patient. The relevant literature is reviewed, and the processes by which metastases form are discussed.

Use of the buccal fat pad as a pedicled graft.

The development, anatomy, and blood supply of the buccal fat pad are discussed, and the results in a series of patients treated with uncovered buccal fat pad grafts are presented.

Mandibular vestibuloplasty using a free mucosal graft. A 2-7 year evaluation.

A long-term follow-up (7-2 years) of 152 patients who underwent a vestibuloplasty is presented. Special emphasis has been put on the condition of the graft, nerve disturbances and chin contour changes. As a result of this study, a mandibular vestibuloplasty procedure is recommended that has minimal side effects, and yet provides an adequate base on which to build a denture on.

Recent developments in interpositional bone-grafting of the atrophic mandible.

A clinical study on 54 patients, who underwent augmentation of the atrophic mandible by interposed bone-grafts, but in whom routine follow-up vestibuloplasty was deliberately avoided, is presented. The results show a reduced rate of bone resorption in the anterior region and less interference with lip and chin sensibility. An additional study is included concerning the fate of the elevated ridge and associated bone-graft in the body region posterior to the mental foramen. Results suggest that the resorption pattern in this area is very similar to that of a subperiosteal bone-graft. Modification of surgical technique in this regard has produced encouraging results.

The posterior segmental maxillary osteotomy: recent applications.

The application of the posterior segmental maxillary osteotomy to the problem of edentulous space closure was studied in 30 patients so treated. The degree of success was based on several criteria, which included stability, periodontal health, occlusion, and response to treatment. A simplified surgical technique is described and useful surgical aids are demonstrated. The existing literature is reviewed in the light of present findings.

The role of the intraosseous osteosynthesis wire in sagittal split osteotomies for mandibular advancement.

Two groups of 20 patients who were treated for mandibular hypoplasia by surgical lengthening of the mandible using the bilateral sagittal split ramus osteotomy were followed pre- and postoperatively using serial lateral cephalograms. One group of patients was treated without internal fixation and the second group, with superior border intraosseous osteosynthesis wiring. Both groups were evaluated for postoperative skeletal and occlusal changes and the results were compared. A notably greater amount of relapse was observed in the group of patients in whom no intraosseous wiring was used.

A modification of the pterygoid plate separation in low-level maxillary osteotomies.

The technical details of a modified procedure for separation of the pterygoid plates in low-level maxillary osteotomies is described. The cut is made through the tuberosity and ends at the posterior aspect of the hard palate, medial and anterior to the pterygomaxillary fissure. This technique provides several advantages over the more classically described posterior vertical cut through the pterygomaxillary suture. The major advantages are that it is anatomically less hazardous and allows greater mobility of the segments. It also permits a larger vascular pedicle to be maintained.

A reappraisal of the interposed bone graft augmentation of the atrophic mandible.

A follow-up on 148 patients who had undergone an interposed bonegraft augmentation of the atrophic mandible is presented. The first group consisted of 38 patients who underwent surgery 4-6 years ago. The second group of 70 patients has a follow-up period of 3 to 4 years. The third group of 40 patients was followed up from 2 to 3 years postoperatively. The phenomenon of post-operative bone resorption which continues for many years postoperatively, is discussed. The high incidence of nerve disturbances as found in this study is regarded as unacceptable. The dissection of the mandibular nerve out of its canal (decompression) in order to avoid nerve damage during the operation is not found to be of any advantage. A modified technique is recommended to circumvent this problem.
