PURPOSE This study analyzed potential risk factors in patients who received radiation therapy and then developed osteoradionecrosis (ORN). PATIENTS AND METHODS A group of 104 patients who developed osteoradionecrosis of the jaws were reviewed treated between 1972 and 1992. RESULTS The most common affected site was the mandible (99 cases, 95.2%),(More)
PURPOSE Few reports have evaluated cumulative survival rates of extraoral rehabilitation and peri-implant soft tissue reaction at long-term follow-up. The objective of this study was to evaluate implant and prosthesis survival rates and the soft tissue reactions around the extraoral implants used to support craniofacial prostheses. MATERIALS AND METHODS A(More)
OBJECTIVE This study evaluated the results of the use of curettage followed by liquid nitrogen spray cryosurgery in a number of solid or multicystic ameloblastomas of the jaws and the postoperative complications related to this treatment modality. STUDY DESIGN Thirty-six patients with solid ameloblastoma of the jaws were treated with curettage followed by(More)
The aim of this study was to compare retrospectively the effect of three different treatments on the healing outcome of bisphosphonate-related osteonecrosis of the jaws (BRONJ) in cancer patients. Twenty-two cancer patients were treated for BRONJ with one of the following protocols: clinical (pharmacological therapy), surgical (pharmacological plus surgical(More)
PURPOSE Osteoradionecrosis (ORN) is a severe and devastating late complication of radiotherapy in patients with head and neck cancer. Management of ORN remains controversial and the current approach has been focused on debridement, systemic antibiotics, and eventually hyperbaric oxygen therapy for small and limited ORN. However, this conservative approach(More)
Actinomycosis is occasionally an opportunistic infection occurrence in patients with osteoradionecrosis (ORN). A retrospective study (1992-97) of 50 patients with ORN of the jaws was done to evaluate the incidence and its clinical significance in the management of ORN. Actinomycosis was diagnosed in 12% of ORN cases. In 36 of the 50 patients including five(More)
The ultrasonographic aspects of 72 intraosseous lesions of the jaws were evaluated to identify the usefulness of this type of examination. The principal aim of ultrasonography was to recognize the lesion's content before surgical treatment. Four groups of lesions were classified after the definitive histopathologic examination: lesions with solid, liquid,(More)
Surgical management of bisphosphonate-related osteonecrosis of the jaws (BRONJ) has been performed in an attempt to increase healing rates of the affected cases. This literature review aimed to identify clinical studies of surgical management of bisphosphonate-related osteonecrosis of the jaws (BRONJ) in order to assess their surgical treatment modalities,(More)
PURPOSE Surgery of irradiated tissue has an increased complication rate because of the development of hypovascular, hypocellular, and hypoxic tissue. This study was undertaken to perform histopathologic and histomorphometric analyses of irradiation tissue injury in bone and the surrounding soft tissues. MATERIAL AND METHODS The histopathologic findings of(More)
