Endoscopic transnasal approach for surgical treatment of skull base clival area chordomas (Report of 2 cases)
-
Abstract: The case 1 performanced submandibular trauma because of the faint Suddenly. There were no obvious abnormality in physical examination. CT result showed that the tumour located in the lower clivus, and the atlas was infringed. MRI imaging showed the tumour located in the both sides of the internal carotid artery,infringed clivus and atlas front, forwarded into the nasal cavity and oral cavity.The case 2 performanced the left nose stuffy and increased gradually, nasopharyngeal mirror showed the left nasal cavity filled with new life. CT showed the lesions located in the cranial fossa under the sella turcica and sphenoid bone,down into the sphenoid sinus and the nasopharyngeal cavity. MRI imaging showed the lesions located in the front of clivus. According to the CT and MRI imaging features before surgery, the two cases adopted endoscopic transsphenoidal approach, and the postoperative pathology were chordoma in the central line of the skull base.
