(1) Conclusion The nasal endoscopic sphenoidal technique for optic decompression have advantages of simple arid minitraumatic approach, that is one of favorable of optic canal decompression.

(2) Methods: Sphenoidal electrodes and HV were done and the epileptiform discharges recording were analysed in 33 children who with normal or non-specific change EEG.

(3) The vertical distance from sphenoidal crest to anterior foramen of the optic canal.

(4) Objectives: To explore the value of sphenoidal electrodes with sleep deprivation EEG in diagnosing epilepsy.

(5) Objective: To explore the diagnosis value of sphenoidal electrodes in child epilepsy.

(6) The sphenoidal saddle and it's peripheral structure of 50 Chinese adult skulls were observed and measured.

(7) The hanging wall of the pterygopalatine space, fora- men rotundum, inferior orbital fissure, pterygoid canal and its relationship with the sphenoidal sinus were dis- played on coronal section.

(8) To measure the imaging anatomical data of the apertura of sphenoidal sinuses and their surrounding structure and to provide clinical guidance for surgeons.

(9) Objective To explore the method and therapeutic effectiveness of microsurgery for medial sphenoidal ridge meningioma.

(10) The choanal polyp may originate in the maxillary sinus, sphenoidal sinus, middle nasal concha, nasal septum and other parts, FESS is the first choice in treating it.

(11) Diffuse mucosal thickening affecting bilateral maxillary sinuses, ethmoidal sinuses and sphenoidal sinuses, suggesting pansinusitis change.

(12) Results: The lesion located in the left choana region and left sphenoidal sinus of this case involved the left pharyngeal mucous space, left infratemporal fossa and its adjacent bone structure.

(13) Objective To explore the diagnostic value of "Standard" EEG, which include common induced test with sleeping induce(1.5 to 2.0 h) and choice sphenoidal electrode description in epilepsy.

(14) Objectives: To analyze the clinical manifestations, imaging and histopathologic features of sphenoidal sinus disease, as well as the choice of method of treatment.

(15) Objective To find out the causes of severe surgical complications of sphenoidal ridge meningioma of and the methods to avoid them.

(16) Conclusion: The choanal polyp may originate in the maxillary sinus, sphenoidal sinus, middle nasal concha, nasal septum and other parts, FESS is the first choice in treating it.

(17) Objective: To study the microanatomical characteristics and surgical significance of sphenoidal segment of cistern in lateral fossa of cerebrum (Sylvian cistern).

(18) Invasive pituitary adenoma is a common pituitary adenoma invading nearby structures such as the sphenoidal sinus, ethmoidal sinus, upper clivus , sellar floor dura and bone.

(19) Objective To improve the diagnostic accuracy of non pituitary lesions in sphenoidal sinus and sellar area.

(20) It is believed that application of CT and angiography and microsurgical technique is helpful for the diagnosis and treatment of sphenoidal ridge meningioma.

(21) Objective To evaluate the value of combined application of nasal endoscope and microscope to pituitary adenoma dissection via transnasal- sphenoidal approach.
