【摘要】： 【目的】本研究在尸頭標本上模擬內(nèi)鏡下經(jīng)鼻腔手術(shù)入路至顱頸交界區(qū)腹側(cè)區(qū)域,觀察入路的顯露范圍并進行相關(guān)數(shù)據(jù)測量,嘗試通過本入路切除齒狀突并磨開斜坡觀察斜坡下暴露的結(jié)構(gòu)。 【材料及方法】45例顱骨干標本、5套寰樞椎標本(未鑒定性別和年齡)。4例漢族成人尸頭濕標本(其中男性尸頭標本3例,女性1例,未鑒定年齡),灌膠制作新鮮尸頭濕標本,防腐處理后保存于陰冷處備用。 【結(jié)果】觀察并測量了骨性標本的解剖標志。4具標本均完成了齒狀突切除。斜坡切開后可以顯露橋腦下部至延髓腹側(cè)結(jié)構(gòu)。 【結(jié)論】內(nèi)鏡下經(jīng)鼻腔—經(jīng)鼻咽腔入路是齒狀突切除的選擇之一。該入路可以顯露斜坡后方腦干腹側(cè)結(jié)構(gòu),是下段斜坡腹側(cè)病變處理的手術(shù)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.
