Professor He Xiaosheng Ma face should be careful is the sign of brain tumor health Sohu-spyair

Professor He Xiaosheng: "Ma face" should be careful is my health – Sohu signs of brain tumor patients, male, age. Symptoms: right facial numbness in the First Affiliated Hospital of The Fourth Military Medical University examination. Preoperative imaging (contrast enhanced MRI): the right cavernous sinus and petrous apex area, clear boundary, mixed signal, obvious heterogeneous enhancement, extrusion of pons. Preoperative diagnosis: right cavernous sinus tumor and petrous apex area, the possibility of large trigeminal schwannoma. Operation method: transsubtemporal petrous approach tumor resection: release of cerebrospinal fluid, lifting the temporal, see middle cranial fossa near midline dural color red, cut through the thickening of the skull base dural tumor tissue, blood rich toughness. On the surface of the tumor, the volume of the tumor was reduced, and the volume of the tumor volume was reduced. With the aid of an electric knife and CUSA, the tumor was excised quickly, and the small part of the body was brown and yellow. Expand open to the nearby tentorial edge, see contact deep tumor and trigeminal nerve closely, total resection of tumor after pulley, oculomotor, abduction and trigeminal nerve and facial nerve clearly visible. The postoperative pathological image: postoperative trigeminal schwannoma (head CT): tumor resection. After operation, the patients recovered well at the time of discharge, mild abducens nerve was limited and facial numbness was alleviated. Analysis of trigeminal schwannoma (trigeminal schwannoma), and acoustic neuroma are benign schwannoma, but the latter is a higher incidence. Trigeminal schwannoma originated from the trigeminal nerve root for trigeminal nerve sheath (Schwann cells) increased gradually evolved, caused by tumors of the lateral facial hypoesthesia (numbness), a few of them have pain but late onset of numbness, the tumor grew, parasellar cavernous development, caused by eye movement disorders, too the first slope can be extended to the contralateral limb caused by brainstem compression long beam damage syndrome (spastic paralysis), also can straddle the petrous apex, posterior cranial fossa and even caused the development of auditory nerve involvement, manifested as tinnitus or hearing impairment. The surgery is difficult, because the tumor is located near the midline area surrounding the brainstem, trigeminal nerve, oculomotor nerve, trochlear nerve, abducent nerve, facial nerve and auditory nerve, and the basilar artery and its branches of the superior cerebellar artery and posterior cerebral artery and other important structures in the shunt exposed resection of the tumor process, once the damage consequence serious or dangerous. In this case, the temporal inferior petrosal bone approach (Kawasa approach) was performed under microscope, combined with electric knife, CUSA and other auxiliary equipment, and the tumor was removed by the block. For the patients with the medial posterior fossa and the superior clivus, the resection of the tumor could be combined with retrosigmoid approach. Trigeminal schwannomas may recur, the residual tumor foundation to stereotactic radiotherapy (gamma knife irradiation). Due to long-term tumor oppression, the trigeminal nerve is damaged, although the total resection of tumor, postoperative recovery of patients with facial feeling is difficult to normal state; through minor operation, if you can do without much disturbance to the surrounding normal nerves, blood vessels and brain tissue, causing no new nerve dysfunction is a rare look forward to.
