[The psammo-osteoid fibroma of the maxilla].

A case of a rare subtype of midfacial ossifying fibroma in a 5-year old child is presented. Fibro-osseous lesions represent a variety of bone proliferations each characterised by different morphological patterns of osteoid production. Psammomatoid ossifying fibroma is characterised histologically by numerous small round ossicles resembling psammoma bodies and is a locally invasive lesion of facial and cranial bones. The histopathology is described. The surgical treatment includes complete resection of the tumour as well as involved bones by means of midfacial degloving. Two years after surgical treatment the child is free from symptoms and tumour recurrence.

Ivory osteoma of the craniofacial skeleton.

The authors describe the clinical presentation, investigation, and surgical management of two cases of benign ivory osteoma of the craniofacial skeleton. In the first case, a bony mass located over the frontal region had become a cosmetic burden to the patient, and she requested removal with minimal morbidity. Accordingly, an endoscopic procedure, with minimal access incisions located behind the hairline, was devised. In the second case, the patient, a Jehovah's Witness, presented with a long history of slowly enlarging bony masses over the maxilla and in the pterygopalatine space. She finally requested surgical intervention when the symptoms of pain related to fifth nerve compression at the foramen ovale became intolerable. Key aspects of the preoperative and perioperative management strategies used to avoid blood transfusion are detailed, as is the surgical approach, which included a bicoronal scalp flap with temporary removal of the zygomatic arch and the coronoid process. Finally, the etiology, histology, and natural history of ivory osteomas are discussed.

Rehabilitation of a bilateral maxillectomy patient with a free fibula osteocutaneous flap.

Rehabilitation of patients who have undergone bilateral maxillectomy is difficult because of extensive loss of bone and soft tissue. In this clinical report, prosthodontic rehabilitation of oral function in a bilateral maxillecitomy patient combined with a new fibular osteocutaneous flap, which was designed to have two oronasal slits for the retention of an obturator prosthesis, was described. A 58-year-old man with a maxillary alveolar carcinoma underwent bilateral maxillectomy. The defect was reconstructed using a vascularized fibular bone wrapped circumferentially with a peroneal flap, which was fixed with miniplates between the right malar prominence and cut edge of the left zygoma remaining two slits anterior and posterior to the graft. Two and half weeks after the surgery, a delayed surgical obturator was delivered and an obturator prosthesis was delivered 6 weeks after the surgery. This obturator prosthesis could be extended into the slits to engage the tissue undercuts, and was stable during use. Mastication, deglutition, articulation and the mid-facial profile of the patient were rehabilitated. After installation of the obturator prosthesis, relining of the prosthesis base was carried out alongside the healing process of the graft, and adjustment of occlusions and high-pressure spots was carried out. No clinical disorders were observed either in the grafted tissue or the obturator prosthesis with a 3-year prognosis. Newly designing a fibular osteocutaneous flap combined with tissue-borne obturator prosthesis is one successful approach to the restoration of oral function, and increases the patient's quality of life after bilateral maxillectomy.

Adult benign granular cell tumor of the maxilla.

A granular cell tumor occurred in the right anterior maxilla of a 22-yr-old black man. It involved the right labial maxillary submucosa and the underlying bone. It also invaded the maxillary sinus and the nasal cavity on the same side. The ultrastructural features of the lesion confirmed the biopsy diagnosis of benign granular cell tumor. The treatment involved partial maxillectomy, split thickness skin graft and immediate dental prosthesis.

Limitations of rotational panoramic radiographs in the diagnosis of maxillary lesions. Case report.

This case report clearly demonstrates that misdiagnosis may result from failure to recognize the limitations dictated by the width of the focal trough in rotational panoramic radiographs. The patient's clinical signs and symptoms were at variance with the findings from the rotational panoramic radiograph. A subsequent radiographic view by the occipito-mental (Water's) projection showed the extent and malignant features of the lesion.

Recurrent calcifying epithelial odontogenic tumor of the maxilla: report of a case with cytologic diagnosis.

BACKGROUND: Calcifying epithelial odontogenic tuor (CEOT) occurs rarely in the maxilla and lacks classical clinicoradiologic features. The cytologic features in conjunction with the radiologic picture can be helpful in making a preoperative diagnosis and guiding management. CASE: A young man with a progressively increasing left cheek swelling and proptosis of the left eye was referred for fine needle aspiration cytology. The smears were paucicellular and showed clusters of mildly pleomorphic squamoid cells; abundant, amyloidlike, pink material; and occasional concentric calcification. A provisional diagnosis of CEOT was given and confirmed on histopathology. CONCLUSION: The characteristic cytologic findings in association with radiologic features can help the cytopathologist in rendering a firm preoperative diagnosis of CEOT even at atypical sites such as the maxilla.

An unusual presentation of a high-grade, non-Hodgkin's lymphoma in the maxilla.

A case of a high-grade, non-Hodgkin's lymphoma affecting the maxillary alveolus which exhibited the classical radiological features of a malignant lesion occurring in the jaws is presented. CT demonstrated considerable upward displacement of an expanded but intact antral floor. Such a feature is more usually suggestive of involvement of the antrum by a benign lesion arising within the alveolar bone.
