1/31. Mesenchymal chondrosarcoma associated with Goldenhar's syndrome.Goldenhar's syndrome is characterised by bony abnormalities of the face, jaw and vertebral column. We report the first case of the development of a primary malignant neoplasm (mesenchymal chondrosarcoma) initially misdiagnosed as a meningioma, occurring in association with this syndrome.- - - - - - - - - - ranking = 1keywords = jaw (Clic here for more details about this article) |
2/31. Metastatic chondrosarcoma to the maxilla: review of the literature and report of case.Metastatic tumors to the jaw are relatively uncommon. When they occur, the primary tumor is most likely to be an adenocarcinoma from the breast, lung, or kidney. Metastatic tumors most frequently involve the mandible rather than the maxilla. The route of metastasis is considered hematogenous, although spread via lymphatic channels or the vertebral venous plexus may occur. An unusual instance of primary chondrosarcoma of the scapula metastasizing to the maxilla and to various soft tissue sites from tumor emboli, probably arising from an extensive metastatic lesion of the left atrium of the heart, has been presented.- - - - - - - - - - ranking = 5.6559054403156keywords = mandible, jaw (Clic here for more details about this article) |
3/31. Radial forearm free tissue transfer for head and neck reconstruction: versatility and reliability of a single donor site.Since its description as a free flap, the radial forearm flap has undergone numerous modifications for reconstruction of various defects in the head and neck region. Fasciocutaneous, adipofascial, osteocutaneous, tendinofasciocutaneous, or osteotendinofasciocutaneous flaps may be designed and transferred from the radial forearm. This article illustrates the versatility and reliability of this donor site in 15 patients with a variety of head and neck oncologic defects who underwent immediate (12 patients) and delayed (3 patients) reconstruction using different free flaps from the radial forearm. skin flaps were used in 11 patients (73.3%) with floor of mouth (4 cases), hemiglossectomy (2 cases) and partial maxillectomy (2 cases) defects, and for scalp (1 case), lower lip (1 case) and a central face (anterior maxilla/upper lip/nasal) (1 case) defect. Osteocutaneous flaps were used in four patients (26.6%) for reconstruction of bilateral subtotal maxillectomy defects (2 cases), a complex forehead and nasal defect (1 case), and for mandible reconstruction (1 case). In addition, the palmaris longus tendon was included with the flap in the two patients that required oral sphincter reconstruction. One patient required reexploration due to vein thrombosis, and no flap failures were detected in this series. The donor site healed uneventfully in all patients, except one, who had partial skin graft failure. Because of their multiple advantages, free flaps from the radial forearm have a definite role for reconstruction of head and neck defects. New applications of composite flaps from this donor site may continue to emerge, as illustrated in some of our patients.- - - - - - - - - - ranking = 4.6559054403156keywords = mandible (Clic here for more details about this article) |
4/31. chondrosarcoma of the anterior mandible. A case report.Chondrosarcomas of the maxillofacial region are extremely rare tumors, accounting for approximately 1% of chondrosarcomas of the entire body. This case represents the 12th case of mandibular symphyseal chondrosarcoma reported in the literature. It presented as a painful swelling of the alveolus, associated with a mobile mandibular incisor. The patient remains free from recurrence six years after a marginal resection.- - - - - - - - - - ranking = 18.623621761262keywords = mandible (Clic here for more details about this article) |
5/31. Penile metastasis of chondrosarcoma of the jaw.Metastasis to the penis is an unusual event. Bladder and prostate tumors are the main sources of penile metastasis. Other sites include the rectosigmoid, kidney, and, less frequently, the pancreas, liver, nasopharynx, and lung. Other sources include malignant melanoma and Burkitt's lymphoma. The differential diagnosis includes idiopathic priapism, venereal or infectious disease, tuberculosis, Peyronie's disease, and primary penile tumor. chondrosarcoma of the jaw is responsible for 10% of all chondrosarcomas that originate with craniofacial bones. Its behavior is usually characterized by local aggression; however, distant metastasis is uncommon. We report a case of chondrosarcoma of the jaw with penile metastasis. This is the first case described in published medical reports.- - - - - - - - - - ranking = 6keywords = jaw (Clic here for more details about this article) |
6/31. skull base dumbbell tumor: surgical experience with two adolescents.Pediatric skull base tumors are rare and until recently were considered unresectable. We present two patients with tumors of similar anatomic position with an extracranial component in the infratemporal fossa and parapharyngeal space, an isthmus at the foramen ovale, and a superior component in the middle cranial fossa in the region of the cavernous sinus. A 15-year-old girl experienced contiguous spread of a spindle cell sarcoma; an 18-year-old boy developed a chondrosarcoma. A middle fossa approach provided the advantage of surgical avoidance of structures such as the middle ear and mastoid, facial nerve, and mandible. Postoperative recovery was rapid. Our impression is that preoperative carotid artery occlusion and a middle fossa approach for tumor resection can be performed in a young patient with acceptable morbidity and at least short-term benefit. Surgery can, therefore, provide an additional therapeutic approach to complement irradiation and chemotherapy.- - - - - - - - - - ranking = 4.6559054403156keywords = mandible (Clic here for more details about this article) |

8/31. Sarcomas of the mandible. literature review and case reports.Sarcomas of the maxillofacial region are rare tumors presenting with wide variety of histopathological and clinical features. The authors treated six patients with sarcomas of the mandible over a period of ten years: 2 patients with fibrosarcomas, 2 with lymphosarcomas, one with osteogenic sarcoma and one with chondrosarcoma. The patients' ages ranged from 28 to 65 years, one was male and five - female. The present study reports three cases (osteogenic sarcoma, fibrosarcoma, chondrosarcoma) with specific clinical and radiographic characteristics, demonstrating the differences between the various types of sarcomas. Special attention is paid to the first clinical signs and symptoms, and to the differential diagnosis with inflammatory conditions (post-extraction alveolitis, chronic odontogenic osteomyelitis), benign tumors (osteoblastoclastoma, ameloblastoma, odontogenic cysts, fibrous dysplasia) and centrally developing jaw carcinomas. Particular emphasis is given to CT imaging and morphological examinations in making an accurate diagnosis and providing adequate treatment. early diagnosis and precise surgical treatment (total resection or hemiexarticulation, or neck dissection if submandibular or cervical metastases are present) are essential to achieve satisfactory management of these malignant neoplasms. The radiotherapy and chemotherapy administered according to the histologic features of the tumor are also of significance.- - - - - - - - - - ranking = 24.279527201578keywords = mandible, jaw (Clic here for more details about this article) |
9/31. Juxtacortical chondrosarcoma of the mandible: report of a unique case and review of the literature.The clinical, radiographic, and pathological features of a juxtacortical chondrosarcoma of the mandible in a 25-year-old Caucasian woman are presented and the differential diagnostic aspects are discussed. To the best of our knowledge, this rare tumor has not previously been reported in the maxillofacial skeleton. Ten years after surgery there is no evidence of local recurrence or metastatic disease. As the prognosis of juxtacortical chondrosarcoma of the long bones seems to be relatively favorable compared with the usual central chondrosarcoma of similar grade of malignancy, this might also be expected for a similar tumor presentation in the maxillofacial skeleton.- - - - - - - - - - ranking = 23.279527201578keywords = mandible (Clic here for more details about this article) |
10/31. chondrosarcoma of the parapharyngeal space. A case report.Chondrosarcomas are the malignant cartilagenous tumors and they are seen rarely in the head and neck area. They are usually slow growing lesions. The head and neck chondrosarcomas may show an aggressive course and the occurrence of this malignant cartilagenous tumor in the parapharyngeal space is only a few. They are mostly located in relation with jaw bones and base of the skull. Chondrosarcomas of the parapharyngeal space are limited in number and among them there is no low-grade one. In this case report, a case of low-grade chondrosarcoma which was treated with a simple excision without neck dissection was reported.- - - - - - - - - - ranking = 1keywords = jaw (Clic here for more details about this article) |
