After the first report of bisphosphonate-related osteonecrosis of the jaw (BRONJ) in 2003, it has increased significantly since then. We report a very rare extensive case never seen before in our experience of bone exposure with necrosis reaching the mandibular inferior border. Although the treatment modalities are not yet established, most researchers have recommended conservative approaches. The surgery was to be as conservative as possible, with a resection of the mandibular range followed by reconstruction using titanium plate with space maintainer. The authors would like to share their approach, management, and awareness.
RESUMEN
Rhabdomyosarcoma is the more frequent mesenchymal tumor in children and in adolescents. It accounts for 60 -70% of mesenchymal tumors and approximately 5% of all solid tumors occurring at these ages. Almost half of rhabdomyosarcomas occur in the head and the neck. We report the case of a 20-year old patient with a new histological, aggressive temporo-parietal rhabdomyosarcoma.

Sarcomatoid carcinoma is a very rare malignant and aggressive tumor that can involve the maxillary sinus. We report the case of a 46 y/o male who presented a tumor of the right maxillary sinus with extension to the right nasal cavity. The diagnosis of sarcomatoid carcinoma was set by histology and immunohistochemistry. The patient received concomitant cisplatin based chemoradiotherapy with no response after 3 months of treatment. He died 6 months later. Through the present case and the review of literature we discuss all aspects of this entity: clinical presentation, differential diagnoses, pathology, treatment and prognosis.

Severe hyperparathyroidism can affect bone metabolism and be in the origine of multiple brown tumours (generalized osteitis fibrosa cystica). When associated with fibro-ossifying tumours of the jaw, it realizes a rare genetic syndrome referred as Hyperparathyroidism-jaw tumour HPT-JT. We report the case of a patient we treated for HPT-JT, and literature review.
RESUMEN
PURPOSE: Frontal sinus fractures represent 2-12% of facial trauma. The purpose of this article is to discuss proper management of these fractures and to evaluate the indications for treatment, the complications and the morphologic results of surgery. MATERIAL AND METHODS: The records of 40 patients admitted to this department with a frontal sinus fracture were reviewed. Sex, age, the circumstances of injury, the imaging techniques, fracture patterns, associated injuries, length of hospital stay, surgical approaches and the complications were analysed. The operations included 3 main options: cranialization, obliteration or reconstruction of the frontal sinus. RESULTS: There were 32 men and 8 women (average 34 years). The most common cause of injury was motor vehicle accidents. Conventional radiography of the face was complemented by computed tomography and 3D reconstructions. Isolated anterior table fractures were found in 72.5% and combined anterior/posterior table fractures in 27.5% of the cases. The treatment was surgical for 70% of the patients; the average length of hospitalization was 1 week. Postoperative complications were: 1 brain abscess, 2 cases of frontal sinusitis and 2 cases of chronic headache. CONCLUSION: Long-term complications in frontal sinus fractures are intracranial infection, sinusitis and forehead defects. To avoid these it was decided to treat all displaced fractures surgically in displaced anterior table fractures the sinus was obliterated with cancellous bone and in displaced posterior table fractures the sinus was cranialized.
