Mandibular odontogenic myxoma : reconstructive considerations by means of the vascularized fibular free flap
The odontogenic myxoma is a rare entity located in mandible and upper maxilla. Due to its local aggressiveness, wide surgical excision is mandatory. Several surgical techniques have been described for the reconstruction of segmental mandibular defects. In comparison with other free flaps, the vascularized free fibular flap (VFFF) supports the longest amount of bone and, due to the nature of the vascular supply a complete freedom in location of the osteotomy is present. A precise mandibular arc can be performed following bone resection. We suggest the performance of the ?in situ? VFFF technique in order to recreate mandibular contour by means of several osteotomies, while the pedicle is stil…
Cavernous sinus metastasis from oropharyngeal squamous cell carcinoma.
Metastasis to the cavernous sinus from head and neck cancer is uncommon and has been previously reported by a few authors. It is usually a late manifestation of the primary tumor and may be the first evidence of a widespread dissemination of the disease. Main clinical findings are those related with involvement of cranial nerves III to VI as they pass through the cavernous sinus. Although diagnosis may be difficult, the appearance of clinical and radiological findings of cavernous sinus involvement in a context of head and neck cancer must alert us about an intracranial metastatic infiltration. In most cases treatment is palliative with radiotherapy and/or chemotherapy. The prognosis of thi…
