Going even lower , there is a more subtle , scattered , and more medially distributed region of abnormally high signal 在向更低的平面,可以看到异常高信号散落分布在一些细小区域。
2.
The natural ostium of the sphenoid sinus can usually be identified medially to the tail of the middle turbinate , approximately 1 cm above the choana 蝶窦的自然口通常位于中鼻甲的后部,后鼻孔上缘
3.
Above and on each side lateral to pituitary are the internal carotid and the anterior cerebral arteries , above which slightly medially are the optic nerves 垂体的上部及侧部是颈内动脉和大脑前动脉,再稍微向上即是位于中间的视神经(略带黄色) 。
4.
The t2 - t11 superior facets face up , back , and slightly laterally ; the inferior facets face down , forward , and slightly medially . this shape enables slight rotation in the thoracic spine 胸2 ~ 11的上关节突的关节面朝向后上方并轻度外旋,而下关节突的节面朝向前下方并轻度内旋。这样胸椎可以轻度的旋转。
5.
Fig . 1 - 29 anterior approach to ankle joint . extensor hallucis longus and tibialis anterior tendons , along with neurovascular bundle , are retracted medially . tendons of extensor digitorum longus muscle are retracted laterally 图1 - 29踝关节前入路。拇趾长伸肌腱和胫骨前肌腱与神经血管束一起向内侧牵开,趾长伸肌腱牵向外侧。
6.
Divide the flexor retinaculum and retract the flexor hallucis longus tendon and the neurovascular bundle posteriorly and laterally ; then by retracting the tibialis posterior and flexor digitorum longus tendons medially and anteriorly , expose the posterior tibial fracture ( fig . 1 - 35 ) 切断屈肌支持带,然后将拇趾长屈肌腱和神经血管束牵向后外侧,并将胫后肌及趾长屈肌腱牵向前内例,显露胫骨后方骨折(图1 - 35 ) 。
7.
Wider access to the joint may be attained in the following ways : ( 1 ) by extending the incision proximally , ( 2 ) by extending the proximal part of the incision obliquely medially and separating the fibers of the vastus medialis , ( 3 ) by dividing the medial alar fold and adjacent fat pad longitudinally , and ( 4 ) by mobilizing the medial part of the insertion of the patellar tendon subperiosteally 还可以通过下述方法扩大手术显露:将切口向近端延长;将切口近端部分斜向内侧延长并分开股内侧肌纤维;纵向劈开内侧翼状襞及邻近的脂肪垫;骨膜下松解髌韧带止点的内侧部分。
