Abstract

Pudendal nerve entrapment clinically has a wide spectrum of presentation ranging from urinary to anorectal and sexual dysfunction. The caliber of the pudendal nerve should be matched with calibre of donor nerve for a successful nerve transfer. Hence, we aimed at evaluating the morphology, dimensions of pudendal nerve at various sites of entrapment and certain trajectory distances to approach the pudendal nerve surgically. The study was conducted at Department of Anatomy at a tertiary care hospital and medical college. A detailed dissection of pudendal nerve was done and the morphology and morphometry of the pudendal nerve were studied in 10 cadavers with equal sex distribution (5 male and 5 female). Crosssectional area (CSA) of the pudendal nerve at various sites of entrapment (piriformis, sacrospinous ligament, sacrotuberous ligament, and at Alcock's canal) and trajectory distance of pudendal nerve from various anatomical landmarks (ischial spine, sacral tuberosity, pubic symphysis, and inferior pubic ramus) were measured using digital vernier caliper. The CSA of pudendal nerve was more at piriformis (4.04 mm2) it decreased as the nerve travelled further to Alcock's canal (0.35 mm2). On comparison of the CSA and trajectory distances of the pudendal nerve with sex and sides there was no statistically significant difference. Morphologically, formation variation of pudendal nerve from S3 and S4 roots and trunk variations were also observed. These findings of the present study would help in various surgeries of perineum like nerve transfer, in placement of Richters stitch, transobturator tapes, pudendal nerve block etc.

具有外科意义的东印度人群阴部神经形态学和形态计量学:一项尸体研究。
阴部神经卡压在临床上有广泛的表现,从泌尿到肛肠和性功能障碍。阴部神经的口径应与供体神经的口径相匹配,才能成功进行神经移植。因此,我们旨在评估阴部神经在不同压迫部位的形态,尺寸和一定的轨迹距离,以手术接近阴部神经。该研究是在三级医院和医学院的解剖学系进行的。对阴部神经进行了详细解剖,并对10具性别分布相等的尸体(男5名,女5名)的阴部神经形态学和形态测量学进行了研究。使用数字游标卡尺测量阴部神经在不同压迫部位(梨状肌、骶棘韧带、骶结节韧带和Alcock管)的横截面积(CSA)和阴部神经到各解剖标志(坐骨棘、骶结节、耻骨联合和耻骨下支)的轨迹距离。阴部神经的CSA以梨状肌为主(4.04 mm2),随着神经向Alcock管的延伸而降低(0.35 mm2)。阴部神经的CSA和轨迹距离在性别和侧位上比较,差异无统计学意义。从形态学上看,阴部神经从S3和S4根和干的形成也发生了变化。本研究结果对会阴的神经移植、里氏缝合、闭锁带、阴部神经阻滞等手术有一定的指导意义。
