Cemento-ossifying fibroma of the mandible.

INTRODUCTION Cemento-ossifying fibroma is a rare benign tumor most often discovered incidentally. CASE REPORT A 72-year-old patient was referred for a subclinical lesion of the mandible. The orthopantomogram showed a well-circumscribed radiolucent osteolytic image, 1 cm in diameter, on the mandibular angle. On CT, the single lesion had a tissue aspect with a peripheral halo without enhancement after contrast injection. A cortical lacuna on the lingual side was noted. Surgical enucleation of the lesion was performed. The pathological examination confirmed the ossifying fibroma. DISCUSSION/CONCLUSION Slow and progressive, cemento-ossifying fibroma is a rare benign tumor that reaches the maxilla and more frequently the mandible. The ossifying and cementifying fibromas are differentiated by their clinical, radiological, and histological findings. The authors discuss the pathogenesis and radiological signs guiding the choice of diagnostic and therapeutic methods. The treatment is surgical with an enucleation or wider resection with bone reconstruction for large fibromas.

Facial resurfacing with split-thickness skin grafts in Xeroderma Pigmentosum variant

Xeroderma Pigmentosum (XP) is a rare systemic disease which is transmitted through an incomplete sex-linked recessive gene. As a result of this, exposure to the ultraviolet (UV) rays of the sun causes malignant skin lesions. One of the most effective treatment options for the malignant lesions is full-face resurfacing with skin grafts. These grafts should be harvested from areas that have not been affected by UV exposure or have at least been minimally affected. The authors present a patient with XP whose face was resurfaced by split-thickness skin grafts taken from the buttocks.

Launois–Bensaude syndrome involving the orbits

BACKGROUND We report the first description of a Launois-Bensaude syndrome involving the orbit. CASE REPORT Launois-Bensaude syndrome was diagnosed in a 70-year-old-man who presented with severe bilateral proptosis (Hertel value 26mm). We performed a bilateral transpalpebral orbital decompression by resection of intraorbital fat without bone removal. The surgery was uneventful. The volume of resected orbital fat was 16cc in both sides. Proptosis reduction was 7mm. Postoperative Hertel values were 19mm in both eyes. CONCLUSION The proptosis was managed successfully. Orbital lipectomy lead to minimal sequelae and, may be repeated if necessary in this case.

Les petits moyens en chirurgie préimplantaire

Osteotomes, the bone scraper, and the bone trap are simple tools used for preprosthetic surgery. They are not very invasive, present little risks, and they can be used in private surgical practice with local anaesthesia. The osteotome preserves, dilates, and condenses the alveolar bone instead of eliminating it like drilling does. It does not require any motor or irrigation. It increases the width and the height of the alveolar crest. It allows the localized expansion of narrow or misshapen alveolar crest when its width ranges between 3 and 4.5mm. It also allows performing a localized sinus lift, when the sinus floor height ranges between 4 and 8mm. The bone scraper is used to retrieve cortical chips of parietal bone for sinus lift. The bone trap is connected to the suction tube. It is used to collect bone powder after milling or bone drilling. These simple tools should be available for all maxillofacial surgeons in specific indications.

Orbital Lipomatosis: A Complication of Steroid Therapy in the Sweet Syndrome

The description of a Sweet syndrome steroid dependant-induced orbital lipomatosis is reported. A 76-year-old-man with history of Sweet syndrome presented with severe bilateral proptosis (Hertel value, 25 mm) with decreased visual acuity and evoked potentials lengthened. A bilateral transpalpebral orbital decompression was performed by resection of intraorbital fat without bone removal. The surgery was uneventful. The volume of resected orbital fat was 15 ml for both sides. Proptosis reduction was 6 mm. Postoperative Hertel values were 19 mm, and evoked potentials were improved. The proptosis was managed successfully. Orbital lipectomy led to minimal sequelae and may be repeated if necessary in this case.

Évaluation tomodensitométrique de la reconstruction des sites donneurs calvariaux par ciment de phosphate de calcium

UNLABELLED The aim of reconstructing a calvarial donor site with biomaterial is to reconstruct the skull vault. The aim of this retrospective study was to assess the quality of reconstruction of calvarial bone with Hydroset™ (Stryker™) in patients having undergone monocortical parietal bone graft harvesting. PATIENTS AND METHOD The donor sites of patients having undergone calvarial bone harvesting had been reconstructed with Hydroset™ cement over a period of four years. Calvarial bone reconstruction and the thickness of the parietal bone were evaluated by CT scan. RESULTS Twenty-six patients had undergone reconstruction. The CT scan revealed a good integration of Hydroset™ with maintained thickness of the biomaterial. The parietal bone thickness was increased by 0.67 mm on average (P=0.002). DISCUSSION The reconstruction of calvarial donor site bone defect with Hydroset™, after a monocortical harvesting, demonstrates parietal osseous thickness maintained in time.
