[Theoretic explanation about visual disorder induced by fibrous dysplasia of skull: pressure disequilibrium between lamina cribrosa].

Objective: To investigate the causes for changes in optic nerve head and visual impairment caused by fibrous dysplasia (FD) of optic canal stenosis.

Methods: A total of 12 FD patients, diagnosed by CT, received the fundus and optical coherence tomography (OCT). Those with FD involving optic canal underwent decompression.

[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.

[Trans-cranio-naso-orbital approach in treatment of ethmoid sinus malignant tumors: analysis of 39 cases].

Objective: To summarize the experience in treatment of ethmoid sinus malignant tumors via trans-cranio-naso-orbital approach. Post-operationally follow-up was conducted in 27 cases for 3.5 years (3 months to 7 years).

[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.
