1/46. Multimodality management of a case of primary osteogenic sarcoma of the zygoma.Craniofacial osteogenic sarcomas are rare primary malignant bone tumors and very few cases involving zygomatic bone were reported in literature. We present our experience of multimodality management of a case of primary osteogenic sarcoma of zygoma. Wide radical excision of the tumor including the parotid gland was done followed by three cycles of adjuvant chemotherapy and fifty Gy of external radiotherapy. The patient is disease-free at two years follow-up. Till 1970s, craniofacial osteogenic sarcomas were managed mainly by radical surgery with a high local failure rate. With the advances made in the field of radiotherapy and chemotherapy, multimodality therapy is playing a major role in the treatment of these aggressive tumors with better overall and disease-free survival.- - - - - - - - - - ranking = 1keywords = craniofacial (Clic here for more details about this article) |
2/46. Aggressive basal cell carcinoma of the temporal region in a patient with Gorlin-Goltz syndrome.Gorlin-Goltz syndrome is an autosomal dominant disorder with variable penetration characterized primarily by five major findings: multiple basal cell carcinomas presenting at a young age, pits on the palms and soles, skeletal abnormalities, jaw cysts, and ectopic calcification of the falx cerebri and other structures. When the basal cell carcinomas are located in the head and neck there is a high risk of invasion of deep structures if early and radical treatment is not performed. The authors present a 59-year-old man affected by basal cell carcinoma in the context of Gorlin-Goltz syndrome. Although patients with this syndrome can present aggressive basal cell carcinomas, it is unusual to find them involving the craniofacial bones. In this patient the basal cell carcinoma involved the middle ear, the intrapetrous aspect of the facial nerve, and the dura mater. The reconstruction of a wide three-dimensional defect, in which the brain was exposed, was achieved with local flaps and a free musculocutaneous rectus abdominis flap. Factors affecting reconstruction in the lateral cranial base are discussed.- - - - - - - - - - ranking = 1keywords = craniofacial (Clic here for more details about this article) |
3/46. Osteosarcomatosis involving craniofacial bones presenting with cranial nerve palsies.Osteosarcomatosis (also known as multifocal osteosarcoma or multiple sclerotic osteosarcoma) is a rare condition, characterized by multiple skeletal lesions at initial presentation. We describe a case of osteosarcomatosis involving craniofacial bones presenting with cranial nerve palsies. In addition, a brief review of the literature is given, with a discussion of this highly aggressive form of osteosarcoma.- - - - - - - - - - ranking = 5keywords = craniofacial (Clic here for more details about this article) |
4/46. The radiological features of craniofacial neurofibromatosis.Three cases of neurofibromatosis are reported showing a wide spectrum of roentgen abnormalities affecting the skull and facial bones. One case had macrocrania and multiple calvarial defects; enlargement of the sella turcica and middle cranial fossa was also present. All the three cases had orbital changes either in the form of enlargement, reduced anteroposterior width or loss of bony outlines with an appearance of emptiness. The other two cases showed predominantly facial involvement with hypoplasia of the mandibular body and ramus, abnormal coronoid process, zygomatic arch, hypoplastic maxilla, cystic mandible with abnormal dentition and absence of the osseous external auditory meatus. Intra-orbital calcification was present in one case. The radiological projections required to evaluate such cases are discussed. The 20 degrees occipito-mental view has been found extremely useful and is recommended.- - - - - - - - - - ranking = 4keywords = craniofacial (Clic here for more details about this article) |
5/46. Malignant giant-cell tumor of the parietal bone: case report and review of the literature.OBJECTIVE AND IMPORTANCE: Giant-cell tumors (GCTs) are primary bone tumors that involve long bones in 75 to 90% of patients. They seldom develop in the cranium and are very rare in patients older than 60 years of age. A GCT rarely occurs with Paget's disease; when it does, however, it is most commonly associated with the polyostotic form and tends to involve the craniofacial bones. Pagetic GCTs are less aggressive than GCTs that are not associated with Paget's disease. CLINICAL PRESENTATION: We report the case of an 81-year-old woman with a painless left parietal mass and asymptomatic monostotic parietal Paget's disease. INTERVENTION: Surgical resection was performed, and histological examination of the lesion demonstrated Paget's disease with a malignant GCT. An incidental, low-grade, small-cell lymphocytic lymphoma also was noted. The patient experienced local recurrence of the malignant GCT and eventually died after developing pulmonary metastases of the malignant GCT. CONCLUSION: This case is the first reported example of a patient with a malignant GCT of the cranium associated with monostotic Paget's disease. It provides evidence that not all pagetic GCTs in the cranium are benign, as has been reported.- - - - - - - - - - ranking = 1keywords = craniofacial (Clic here for more details about this article) |
6/46. A rare tumor of craniofacial bones in children: a pediatric chondroblastic osteosarcoma case with diagnostic and therapeutic problems.osteosarcoma of the cranial facial region is uncommon and only rarely involves the ethmoid or sphenoid bones. The authors report on an unusual case of a 17-year-old male presenting with chondroblastic osteosarcoma of the maxillary, ethmoid, and sphenoid sinuses who remains well and disease-free at 46 months. He was treated with anterior craniofacial resection followed by postoperative radiotherapy to the sight of the primary tumor. He did not receive chemotherapy because of emerging hepatitis-B infection and vasculitis. The literature on extragnathic craniofacial osteosarcomas is reviewed with particular emphasis on treatment options of this rare tumor.- - - - - - - - - - ranking = 6keywords = craniofacial (Clic here for more details about this article) |
7/46. Temporalis muscle flap for craniofacial reconstruction after tumor resection.Temporalis muscle flap provides a good solution for the reconstruction of craniofacial defects after tumor resection. Nine patients with complicated defects located at the upper two thirds of the face, anterior cranial base, or mastoid region are presented. Five patients had orbital exenteration, two with total maxillectomy and two with anterior craniofacial resection. Temporalis muscle flap provided profuse well-vascularized tissue for the obliteration of orbital exenteration and total maxillectomy cavities and coverage of surface defects. Cranial, oral, and nasal spaces were separated successfully in all patients. Temporalis muscle flap is a very reliable technique with low complication rates and few donor site problems. This safe and technically easy flap can be preferred for the reconstruction of craniofacial defects after ablative tumor surgery, especially in older and debilitated patients.- - - - - - - - - - ranking = 7keywords = craniofacial (Clic here for more details about this article) |

9/46. Reconstructive challenges in the management of a rare case of sphenoid osteosarcoma--a case report.Primary osteosarcoma of the sphenoid bone is an extremely rare condition. This paper presents a case of a lady with recurrent oesteosarcoma of the sphenoid bone who had resection of the tumour via a combined neurosurgical and craniofacial procedure and reconstruction with a free flap and bone graft. It details the diagnosis, treatment and follow-up of this unusual condition.- - - - - - - - - - ranking = 1keywords = craniofacial (Clic here for more details about this article) |
10/46. osteosarcoma arising from the skull--case report.A 20-year-old male presented with an osteosarcoma in the right parieto-occipital bone occurring as a painless occipital lump which had rapidly enlarged in the 6 months prior to admission. The neuroimaging appearance resembled intraosseous meningioma. Gross total resection of the tumor was achieved. The final histological diagnosis was osteosarcoma. Osteosarcomas of craniofacial region have a better prognosis than those of the skeletal bones, and distant metastasis is rare. Local recurrence is the most significant factor contributing to poor outcome. Complete excision with negative margins is the key to a better outcome. Adjuvant therapy may be an option in cases of incomplete excision. Advances in target chemotherapy may diminish the significant morbidity associated with these lesions.- - - - - - - - - - ranking = 1keywords = craniofacial (Clic here for more details about this article) |
