Since the beginning of this century, trans-
naso-sphenoidal resection of the pituitary fossa
tumors has been widely used clinically. It has
more merits than other operative approaches
used before. In China it has been adopted by
both ENT doctors and neurosurgeons since 1959.1
In order to afford some relevant anatomical
data, we measured 137 adult sagittal plane
skulls with distinct landmarks. 相似文献

Background:Epidural injection is an important method in treatment of protrusion of lumbar intervertebral disc.Especially in the recent decade sacral injection is adopted more and more often.Objective:To compare the clinical effects of sacral blocking and massage combined with traction.Unit:Yinhe Hospital of Beijing.Subjects:290 outpatients with grade Ⅱ of ASAI were selected from May,1994 to July,2000.Patients were randomly divided into observation group(n=145)and control group(n=145).Sacral blocking was adopted in observation group and 80 males and 65 females aged 20-78(mean:46.4)years old were included with disease course 3 days to 30 years.Massage combined with treaction was adopted in control group and 74 males and 71 females aged 22-74(mean:44.9)years oled were inmcluded with disease course 2 days to 10 years.Interention:Sacral blocking:Operation was according to sacral blocking and druge(dexamethasone injection,2 mg;0.75% bupivavaine hydrochloride,5 ml;saline,50ml) were injected slowly after success of puncture.Patient rested for 0.5h after injection and left treatment room if no adverse effects occurred.Massage combined with traction:Massage was adopted after traction to every patients.(1)Massage:Patient was seated at square stool and lower limbs separated naturally with same width of shoulders.Doctors sit behind patient.First,thubs of both hands were pressed on projecting part near spinous process(pressing points were selected according to different projecting part).Flexing and extending forward and backward were taken at the same time and extent was ddecided addording to patients‘ maximal endurable degree,5-10 timmes.Upper part of body was turned 45 degrees to left and right.Massage was still taken to affected part,3-t times.(2)Traction:Pelvis was extracted with general physical therapy and massage table.Supine position,chest and treaction bandage were fixed,tractiron wheel was turned slowly until patient felt comfortable with maximal endurance as limit(traction force,20-40kg),After extracting for 5 minutes,massagee switch was turned on to take rolling massage to bck and both lower libmbs.Traction force was increased every5 minutes and limit was still according to patient‘s maximal endurance,30 minutes for every time,once a day and ten times as a therapeutic course.Cohclusion:Effect of sacral blocking on protrusion of lumbar intervertebral disc was positive and fewer therapeutic time were needed.Massage combined with traction was also effective,safe and no adverse effects wer observed,but more therapeutic times were neeeded and inconveinient. 相似文献

目的:探讨输尿管结石继发息肉发病机制,预防漏诊漏治。方法:1991年1月至2001年12月,采用开放手术和输尿管镜手术治疗输尿管结石继发息肉66例。结果:66例经病理证实为炎性息肉,64例痊愈,开放手术组有2例出院后反复出现尿路感染,其中1例致输尿管狭窄再手术,40例获随访,结石无复发,肾功能改善或恢复。结论:输尿管结石继发息肉术前确诊十分困难,如果漏治,必将导致结石复发;在诊治输尿管结石继发息肉中,输尿管镜手术较开放式有其优势,但技术要求较高。 相似文献
