Objectives: To explore the anatomy of the ventral clivus and adjacent structure in the endoscopic surgery through the anterior approach, particularly in accurate locating lesions in transnasal endoscopic surgery.
Patients And Methods: A total of 9 formalin-fixed adult cadaver heads were injected with red and blue latex to observe the arteries and veins, respectively. The relationships between various parts of internal carotid artery (ICA) and anatomic structures of clivus were investigated, followed by the measurement of the posterior pharyngeal wall, anterior wall and posterior wall of clivus, cerebral dura mater, subdural space and adjacent regions to determine their correlations, as well as the clivus and adjacent structures.
Objective: To describe an endoscopic perspective of the surgical anatomy of the trigeminal nerve.
Methods: Nine adult cadaveric heads were dissected endoscopically.
Results: Opening the pterygopalatine fossa is important because many key anatomical structures (V2, pterygopalatine ganglion, vidian nerve) can be identified and traced to other areas of the trigeminal nerve.
[Application of neuroendoscope in the treatment of skull base chordoma].

Objective: To further explore the application, approach, indication and prognosis of neuroendoscope treatment for skull base chordoma.
Methods: A total of 101 patients of skull base chordoma were admitted at our hospital from May 2000 to April 2010. There were 59 males and 42 females.
Background: To describe the clinical presentation of suprasellar cysts (SSCs) and surgical indications, and compare the treatment methods of endoscopic ventriculocystostomy (VC) and ventriculocystocisternotomy (VCC).
Methods: We retrospectively reviewed the records of 73 consecutive patients with SSC who were treated between June 2002 and September 2009. Twenty-two patients were treated with VC and 51 with VCC.
Background: Endoscopic cystocisternotomy is one of three surgical methods used to treat middle cranial fossa arachnoid cysts. There is debate about which method is the best.
Objective: The aim of this study is to evaluate the effectiveness and safety of endoscopic cystocisternotomy for treatment of arachnoid cysts of the middle cranial fossa.
Objective: To investigate and evaluate the effectiveness of neuroendoscopic therapy for arachnoid cysts of middle cranial fossa.
Methods: From January 2004 to June 2009, 32 patients with arachnoid cysts of middle cranial fossa who were treated with endoscopic cystocisternal fenestration were retrospectively analyzed. There were 21 male patients and 11 female patients, aged from 6 months to 39 years.
Objective: To evaluate the change of CSF dynamics using MR PC Cine for neuroendoscopic third ventriculostomy.
Methods: 146 cases of hydrocephalus were treated by neuroendoscopic third ventriculostomy including 36 cases checked with MR PC Cine study randomly. The successful result was assessed by clinical symptom and imaging study.
Objective: To explore the diagnosis and microsurgical treatment of giant cell tumor (GCT) of skull.
Methods: The investigators reviewed the clinical features, operative approach and prognosis of 23 consecutive cases of GCT of skull operated at our department between July 2000 and November 2008.
Results: Headache was the most common presenting symptom (86.
Objective: Estradiol (E2) acts to modulate the ratio of two dopamine D2 receptor isoforms (D2L/D2S) by the nuclear estrogen receptor (ER) and to reduce dopamine's inhibitory action on PRL secretion. Here we demonstrate the correlation between the expression of ER mRNA and D2R mRNA isoforms in pituitary neoplasms cells.
Methods: Twenty-four human pituitary adenomas (14 prolactinomas and 10 gonadotrope tumors) were examined for the expression of both ER mRNA and D2R mRNA by means of semi-quantitative RT-PCR analysis.
Objective: To analyze the clinical manifestation and neuroendoscopic techniques in treatment of suprasellar arachnoid cysts.
Methods: Between October 2000 and June 2006, 42 patients (22 male and 20 female with a mean age of 10.4 years) with suprasellar arachnoid cysts were treated by endoscopy.
[Endoscopic third ventriculostomy in treatment of obstructive hydrocephalus].
Zhonghua Yi Xue Za Zhi
November 2006
Objective: To explore the effects, influencing factors, and complications of endoscopic third ventriculostomy for obstructive hydrocephalus.
Methods: The clinical data of 55 patients with obstructive hydrocephalus, 29 males and 26 females, aged 18.4 (6 months - 59 years), who underwent endoscopic third ventriculostomy were analyzed retrospectively.
