Application of neuroendoscopic surgical techniques in the assessment and treatment of cerebral ventricular infection.

Cerebral ventricular infection (CVI) is one of the most dangerous complications in neurosurgery because of its high mortality and disability rates. Few studies have examined the application of neuroendoscopic surgical techniques (NESTs) to assess and treat CVI. This multicenter, retrospective study was conducted using clinical data of 32 patients with CVI who were assessed and treated by NESTs in China.

Surgical Indications of Exploring Optic Canal and Visual Prognostic Factors in Neurosurgical Treatment of Tuberculum Sellae Meningiomas.

Background: Tuberculum sellae meningiomas (TSMs) present a special symptom because of the adherence and compression to the optic nerve, optic artery, and the chiasm. A significant number of patients with TSMs appear visual deficits. This study aimed to investigate the surgical indications of exploring the optic canal and visual prognostic factors in the neurosurgical treatment of TSMs.

Sphenoid wing meningioma en plaque: report of 37 cases.

Background: Sphenoid wing meningioma en plaque is a special morphological subgroup of intracranial meningiomas, defined by a carpet-like, soft tissue component that infiltrates the dura and invades the sphenoid wing and orbit associated with a significant hyperostosis. This report summarized our experiences in 37 patients with sphenoid wing meningioma en plaque who had been treated with transcranio-orbital approach surgery.

Methods: A retrospective study was made on clinical manifestations, neuroradiological features, and operative techniques in 37 patients undergoing transcranio-orbital approach from Sep.

[Neurosurgical therapy of transorbital intracranial foreign bodies: review of 28 cases].

Objective: To discuss the benefits and complications of the neurosurgical therapy in transorbital intracranial foreign bodies.

Methods: The clinical data of 28 cases of transorbital intracranial foreign bodies, metallic in 13 cases, vegetal 5 cases, and vitreous, plastic and other kinds in 10 cases, were analyzed retrospectively. Optic nerve injury was found in 13 cases, orbital apex syndrome in 11 cases; CSF rhinorrhea in 13 cases, CSF orbital leak in 3 cases, and hemiplegia in 2 cases.

[Clinical study of lacrimal gland tumor involving anterior and middle cranial fossae].

Objective: To investigate the clinical manifestations of lacrimal gland tumor involving the anterior and middle cranial fossae and the effect of transcranial-orbital approach in treatment of such tumor.

Methods: A retrospective study was conducted on the clinical data of 23 cases lacrimal gland tumor involving the anterior and middle cranial fossae confirmed by radiological examination, including 11 cases of adenoid cystic carcinoma, 6 cases of pleomorphic adenocarcinoma (malignant mixed tumor), 2 cases of adenocarcinoma, 1 case of squamous cell carcinoma, 1 case of ductal carcinoma, 1 case of mucoepidermoid carcinoma, and 1 case of benign mixed tumor, 15 males and 8 females, aged 42.5 (2 - 76), with a case history of 43 months (2 months to 27 years), with the chief complaints of progressive proptosis, disgenesia of the eye ball, and orbit pain, all undergoing transcranial-orbital operation from August 1998 to February.

[Endoscopic decompression of optic canal].

Objective: To evaluate the effectiveness of endoscope in the treatment of optic nerve injury.

Methods: Thirteen patients with fracture at the inner and lower walls of optical canal underwent endoscopic decompression. The posterior 1/3 of the middle concha, the posterior ethmoid sinus and sphenoid sinus were opened, chips of bone and old hematocele were scavenged, and the optic ring of the optic canal was polished; however, the sheath of the optic nerve remained intact.

[Traumatic Rollel's syndrome treated with decompression of orbital apex].

Objective: To observe the efficiency of decompression of orbital apex operation for the treatment of traumatic Rollel's syndrome.

Methods: Eleven patients with Rollel's syndrome were operated using two different approaches of decompression of orbital apex according to the location of the lesion. Five cases were treated by trans-frontal approach and 6 cases by trans-pterion approach.

[Surgical treatment of fibrous dysplasia of the skull with neuro-navagation].

Objective: To evaluate the role and effect of neuro-navagation in the surgical treatment of fibrous dysplasia of the skull and to discuss the indication and advantages of transcranial optic nerve decompression are discussed.

Methods: Fifteen patients with fibrous dysplasia of skull, 6 males and 9 females, aged 10.3 (5 approximately 21), were surgically treated by transcranial approach.

[Transcranial optic nerve decompression for optic nerve injury].

Objective: To discuss the operative indications and advantages of transcranial optic nerve decompression in treatment of optic nerve injury resulted from skull base fracture.

Methods: The data, such as the site of impact, vision, ocular movement, characteristic of CT, and pathologic changes during operation, and the extent of operative decompression of 118 patients with optic nerve injury. According the site of impact on the head, 87 of lateral superciliary arch type, 18 of medial superciliary arch type, and 13 of zygomatic type, undergoing transcranial optic nerve decompression were analyzed retrospectively.
