发布时间：2018-08-18 14:45
【摘要】： 【目的】本研究在尸头标本上模拟内镜下经鼻腔手术入路至颅颈交界区腹侧区域,观察入路的显露范围并进行相关数据测量,尝试通过本入路切除齿状突并磨开斜坡观察斜坡下暴露的结构。 【材料及方法】45例颅骨干标本、5套寰枢椎标本(未鉴定性别和年龄)。4例汉族成人尸头湿标本(其中男性尸头标本3例,女性1例,未鉴定年龄),灌胶制作新鲜尸头湿标本,防腐处理后保存于阴冷处备用。 【结果】观察并测量了骨性标本的解剖标志。4具标本均完成了齿状突切除。斜坡切开后可以显露桥脑下部至延髓腹侧结构。 【结论】内镜下经鼻腔—经鼻咽腔入路是齿状突切除的选择之一。该入路可以显露斜坡后方脑干腹侧结构,是下段斜坡腹侧病变处理的手术入路之一。
[Abstract]:[objective] to observe the exposure range of the approach and to measure the relevant data by simulating endoscopic transnasal approach to the ventral region of the craniocervical junction on cadaveric specimens. This approach was used to remove odontoid process and grind the slope to observe the structure of subclival exposure. [materials and methods] there were 5 sets of atlantoaxial specimens (not identified sex and age) in 45 cases of cranial trunk. 4 cases of Han nationality Adult cadaver head wet specimen (male cadaveric head 3 cases, male cadaveric head 3 cases, A case of female (unidentified age) was gelled to make wet specimen of fresh cadaveric head. [results] the anatomic marks of bone specimens were observed and measured. The inferior part of the pontine to the ventral medulla oblongata can be exposed after clivus incision. [conclusion] Endoscopic transnasal and transnasopharyngeal approach is one of the options for odontoidectomy. This approach can reveal the ventral structure of the posterior Clivus brainstem and is one of the operative approaches for the management of the lower Clivus ventral lesions.
