Chondrosarcoma of the nasal septum extending into the maxillary sinus.

A case of chondrosarcoma of the nasal septum extending into the maxillary sinus is presented. These cartilaginous tumors are rare in the head and neck, with only 21 reported in the maxilla and four in the nasal septum. Careful histologic analysis is required for correct diagnosis. The present case was treated with an en bloc ethmoidectomy and medial maxillectomy, followed by fast neutron radiation therapy. The therapeutic program is analyzed for opportunity to provide an excellent chance of cure.

Facial bone scintigraphy. VIII. Diagnosis of malignant lesions in the maxillary, ethomoidal and palatal bones.

The results from radiographic and scintigraphic examination of 28 patients with malignant tumors of the nasal, paranasal and palate regions, 23 patients with purulent maxillary sinuitis, and 15 control cases were compared. A combination of radiography and scintigraphy yielded the best information on the differentiation between an inflammatory condition and malignant tumor and the extent of malignant growth in adjacent bone.

Cemento-ossifying fibroma of the orbit.

Cemento-ossifying fibroma presents with ophthalmic symptoms and signs rarely. We report the clinical and pathological findings in a case of cemento-ossifying fibroma of the right maxilla with extension into the orbital floor causing intermittent vertical diplopia, proptosis, and upward displacement of the globe. Compression of the nasolacrimal duct produced epiphora early in the course of the disease. Fibrous dysplasia has often been diagnosed in other cases of benign monostotic fibro-osseous conditions. Ossifying fibroma is easily confused with fibrous dysplasia. The histopathological difference between the two lesions is described.

Myxoma of the maxilla: report of case.

A review of the literature and a report of a case of myxoma of the maxilla in a 1-year-old Negro girl have been presented. This case is interesting because of its rarity at this age and its location. Originally, a Weber-Ferguson approach was considered. However, a transoral approach provided excellent access for complete visualization and removal of the tumor. This reinforces the advantages to the patient that result from the cooperation of different surgical services.

Ultrastructure of odontogenic keratocysts.

The ultrastructural features of an odontogenic keratocyst are described. The results of the investigation suggest that the basal lamina complex in the odontogenic keratocyst appears to be morphologically normal. The frequently observed splitting of the epithelium from the capsular tissue is marked by the separation of the epithelium and the basal lamina complex from the connective tissue. The morphologic features of the parakeratinized surface zone of the epithelium suggest that the odontogenic keratocyst may be characterized by "incomplete" parakertinization.

An approach to total maxillectomy with emphasis on orbital preservation.

In view of recent reports suggesting that the orbital contents may be preserved in total maxillectomy for maxillary sinus carcinoma in cases where gross tumor is not found to invade the orbital periosteum, a technique has been presented that emphasizes the preservation of the orbital contents with the restoration of function. The main differences between this technique and the classical one are (1) a modified incision designed to reduce lower lid complications, (2) the preservation of the malar eminence, (3) the preservation of the premaxilla and teeth, and (4) the use of lyophilized dura as a sling for the remaining orbital contents.

Primary insertion of implants in the zygomatic bone following subtotal maxillectomy.

A case of maxillary carcinoma treated with primary insertion of Brånemark implants into the zygomatic bone following subtotal maxillectomy is reported. This method has several advantages. First, early detection of postoperative recurrence is easier than with closing the flap. Second, when the implant is inserted into the midfacial region, zygomatic bone can be useful because of thickness. In addition, applying a maxillary prosthesis in the early stages avoids contracture of facial soft tissue. This primary reconstructive method is effective in cases of preserved zygoma after total maxillectomy.
