Reports of the transcervical approach for resection of skull base tumors are rare, although it was described for resection of clival chordomas in as early as 1966. The purpose of this study is to review our experiences in management of lateral skull base tumors using the transcervical approach. Study Design Retrospective chart review. Methods Six lateral skull base tumor cases treated with transcervical approach procedures were reviewed, including the medical records. Results There were 4 males and 2 females. Age ranged from 12 through 52 years. Histopathological diagnoses included malignant schwannoma(n = 1), malignant carotid body tumor(n = 1), heamangioma(n=1), schwannoma (n=2) and pleomorphic adenoma (n = 1). Transcervical techniques were used in all cases with the use of microscope in the lateral skull base area. Complete tumor removal was achieved in all cases. Postoperative radiotherapy was implemented in 1 case of malignant schwannoma and 1 case of malignant carotid body tumor. Jugular foramen syndrome occurred as a surgical complication in 1 case of malignant Schwannoma of the vagus nerve. There was no tumor recurrence during the 10 - 42 month follow-up period. Conclusion Compared with conventional approaches, the transcervical approach provides a easy, safe, minimal invasive and effective procedure for removal of selected lateral skull base tumors.展开更多

Some may attain great size. Correct radiological assessment and complete removal of the tumor and its capsule are essential for adequate surgical treatment and good long-term prognosis. We report two cases of intradiploic epidermoid cysts of the skull, with giant and CT-hyperdense lesions with extra and intracranial extension, and analyze the clinicopathological and imaging features and treatment of these lesions in the light of the most important published data.展开更多

We presented 3 patients with recurrent ameloblastoma in the anterior skull base including the frontotemporal fossa and the pterygomaxillary fossa that occurred following multiple enucleations, segmental mandibulectomy, or partial maxillectomy for ameloblastoma in the jaws. Attenborough approach was used in the exposure of the frontotemporal fossa. Attenborough plus Barbosa approach was used in the exposure of the pterygomaxillary fossa. The patients were treated by radical dissection. Microscopy confirmed that the histopathologic pattern of one case was fixed follicular and plexiform, two cases were follicular. All patients healed without serious complications. The local recurrences of the patients following the operations were found in 3 to 4 years. The present study showed that the tumors in the regions had a greater recurrence potential even when treated with radical dissection, and the original tumors were the high-risk follicular pattern.展开更多
Objective: To introduce the method of a modified transcranial approach for resection of paranasal sinuses tumors involving the anterior skull base and to address our experience with the approach. Patients and Methods:...Objective: To introduce the method of a modified transcranial approach for resection of paranasal sinuses tumors involving the anterior skull base and to address our experience with the approach. Patients and Methods: Ten cases were operated by the approach. Among them, 4 suffered from benign meningeomas, 6 with malignant tumors included one chondrosarcoma, two malignant meningeomas, two olfactory neuroblastomas, and one squamous sarcoma. Of the patients, 4 cases had primary tumor and 6 cases had recurrent tumors. Result: All of the ten cases underwent operation and no postopertion complication occurred. 7 cases have survived for one to four years without tumor recurrence. 3 cases with malignant tumor died of tumor relapse in one to two years. Conclusion: This method significantly has helped to reduce the persistence and recurrence of the disease.展开更多

The incidence of primary osteogenic sarcomas of the skull is about 1% to 2% of all skull tumors. Methods: We present an extraordinary case of osteosarcoma arising in the postero-temporal region of the skull. The clinical features, diagnosis and management are discussed. Results: A 34-year-old woman was operated in our department for mass, fixed to bone in the left postero-temporal area. Histopathology confirmed the diagnosis of osteogenic sarcoma. Conclusion: We review the literature of reported cases of primary osteogenic sarcomas of the skull to discuss the common clinical presentation, evaluation methods, and recommended treatment plans.展开更多
