Results The superior wall of cavernous sinus, longitudinal trapezoid in shape, was limited laterally by anterior petroclinoid ligament and lateral margin of anterior clinoid process, and medially by the dura of the diaphragma sellae, anteriorly by the base of anterior clinoid process and the falciform dural fold, and posteriorly by the posterior petroclinoid ligament.

结果 海绵窦上壁呈纵长的四边形。外侧界为前床岩韧带和前床突外缘；内侧界为鞍隔的硬膜缘；前界为前床突基底部和镰状硬膜皱褶；后界为后床岩韧带。

Along the membrane, the cavernous sinus can be reached. After drilling the posterior clinoid process, exposing the dorsum sellae and the upper clivus, the superior segment of the basilar artery can be exposed.

结果 磨除前床突后形成的间隙为床突间隙；前床突下颈内动脉与动眼神经间的膜为颈内动脉动眼神经膜，沿此膜可进入海绵窦；磨除后床突后，暴露鞍背、上斜坡，即可显露基底动脉上段。

Results With orbitozygomatic approach, drilling the anterior clinoid process got a space called the clinoid space. The membrane between the internal carotid artery beneath the anterior clinoid process and the oculomotor nerve is called carotidoculomotor membrane. Along the membrane, the cavernous sinus can be reached. After drilling the posterior clinoid process, exposing the dorsum sellae and the upper clivus, the superior segment of the basilar artery can be exposed.

结果 磨除前床突后形成的间隙为床突间隙；前床突下颈内动脉与动眼神经间的膜为颈内动脉动眼神经膜，沿此膜可进入海绵窦；磨除后床突后，暴露鞍背、上斜坡，即可显露基底动脉上段。

Grinding the ossea of the Kawase triangle can expose clivus from the floor of the middle cranial fossa and come into posterior cranial fossa.

磨除Kawase三角的骨质可以从中颅窝底暴露上中斜坡，从中颅窝底进入后颅窝，可以施行椎动脉瘤的夹闭术。

Comclusion: transpetrous presigmoid retrolabrinth approach was rational approach for surgery on petroclivus and -4- CPA; it抯 important for accomplish the surgery to study and master the anatomy and variance of this approach; there was relative anatomical relationship among those structure on posterior of petrous bone; AAMP was the extracranial mark of inflexion of TS and SS; LAM and PSC were obvious bone marks for operation; we can confirm the abraded range of petrous bone lean upon LAM and/or GSS beside abrading step by step as literature, and it抯 unnecessary and unrational to emphasize to show PSC if the surgical space was enough; preceding sigmoid sinus and high jugular bulb often appeared at right and would bring disadvantage effect; interspace ,between CN V and CNVII or CNVII and CNJXI, were available to reach clivus and manage the mass on the range.

经SS前迷路后入路是处理岩斜坡区、桥小脑角区病变理想的手术入路；研究和熟悉手术入路中的解剖结构及部分变异对指导手术十分必要；岩骨内测面的骨性结构之间有着相对稳定的空间关系；顶乳缝前角是SS和TS转接处在颅外的标志；IAM和PSC等结构可以作为手术中的重要骨性标志；以PSC确定岩骨的磨除范围是较安全和可靠的，但亦可以结合影像检查，以内耳道和乙状窦前缘为基点判定切除范围，如果操作空间足够，过分强调磨出半规管是不适当的；右侧GSS的宽度和深度较对侧大，SS前置和颈静脉球高位较对侧多见，这些都对右侧入路有不利的影响，但仍可以进行手术操作；三叉神经和面神经间隙及面l 神经和舌咽神经间隙方便到达斜坡并处理病变。l

Inferior petrosal sinus extends from the posterior part of the cavernous sinus and courses along the clivus laterally, in IPS sulcus. It usually leaves cranial cavity through the jugular foramen and eventually joins the jugular bulb or the internal jugular vein.

岩下窦起自海绵窦后端，走行在斜坡两侧的IPS沟内，通常经颈静脉孔出颅，最终汇入颈静脉球或颈内静脉，沿途接收多条静脉的注入，与颅神经Ⅵ、Ⅸ、Ⅹ、Ⅺ关系密切。

The available operation range in clivus and anterior cranial base by transsphenoidal opproach was also observed during the operation under the help of neuronavigational pointer. Forty-one patients underwent sublabial, transseptal, transsphenoidal approach to the pituitary region guided by Surgical Microscope Navigation was studied. The piriform aperture was 27. 2mm±3. 1 , the origin of inferior nasal concha 30mm±4. 1, the origin of middle nasal concha 27. 9mm±4. 3. These data are important for transsphenoidal approach, because the piriform aperture and the origin of both inferior and middle nasal conchas restricted the opening width of the Hardy specula. If any distance of these bony structures was much less than the mean one, may cause inadequate opening of the specula blade and resulting dissatisfied operative field. Microadenomas or cystic tumors perhaps can be operated even in a narrow exposure, but large or giant solid adenomas may need a proper evaluation including changing the operative approach or performing a bilateral submucous inferior conchotomy or posterior ethmoidectomy firstly.

手术中还利用CT导航系统观察棒研究了经口—鼻蝶窦入路在斜坡区和前颅底能够达到的实际有效操作范围，为扩大经蝶窦入路手术在斜坡区和前颅底的应用奠定基础，在国内外尚未见同类报道。41例垂体瘤患者梨状孔平均宽度27.2mm±3.1，下鼻甲根部附着处间距30mm±4.1，中鼻甲根部附着处间距27.9mm±4.3，这是经口—鼻蝶窦入路手术中，对Hardy双瓣鼻窥器张开限制的主要骨性结构，若患者这些径线值明显小于平均值，则可能因为鼻窥器打开不充分而影响手术暴露，当然对于垂体微腺瘤和以囊变为主的垂体瘤可能影响不大，但对于大和巨大垂体瘤必须要有充分的准备，包括评估是否改用其他入路，或先行鼻甲切除再行经蝶手术。

METHODS: 10 mL bone marrow was extracted from dog posterior superior iliac spine, heparin anticoagulation, diluted using Hanks juice, treated with 1.077 g/mL Ficoll solution 3 mL, and centrifuged at 2 000 r/min for 20 minutes. Karyocytes were absorbed to form white cloudlike layering interface, and then centrifuged twice using DMEM supplemented with fetal bovine serum, incubated at 12×104/cm2 at 37 ℃ in a 5% CO2 incubator.

于犬髂后上棘抽取骨髓液10 mL，肝素抗凝，Hanks液稀释后，加入1.077 g/mL Ficoll液3 mL，2 000 r/min离心20 min，吸取有核细胞形成白色云雾状的分层界面，用含胎牛血清的DMEM离心2遍，按12×104/cm2密度接种，于37 ℃、体积分数为5%的CO2培养箱内培养。
