ABSTRACT
OBJECTIVE@#To preliminarily verify the effectiveness of self-designed artificial condyle-mandibular distraction (AC-MD) complex in the treatment of Pruzansky type ⅡB and Ⅲ hemifacial microsomia (HFM) through model test.@*METHODS@#Five children with Pruzansky type ⅡB and Ⅲ HFM who were treated with mandibular distraction osteogenesis (MDO) between December 2016 and December 2021 were selected as the subjects. There were 3 boys and 2 girls wih an average age of 8.4 years (range, 6-10 years). Virtual surgery and model test of AC-MD complex were performed according to preoperative skull CT of children. The model was obtained by three-dimensional (3D) printing according to the children's CT data at a ratio of 1∶1. The occlusal guide plate was designed and 3D printed according to the children's toothpaste model. The results of the model test and the virtual surgery were matched in three dimensions to calculate the error of the residual condyle on the affected side, and the model test was matched with the actual skull CT after MDO to measure and compare the inclination rotation of the mandible, the distance between the condylar of the healthy side and the residual condyle of the affected side, and the lengthening length of the mandible.@*RESULTS@#The error of residual condyle was (1.07±0.78) mm. The inclination rotation of the mandible, the distance between the condylar of the healthy side and the residual condyle of the affected side, and the lengthening length of the mandible after 3D printing model test were significantly larger than those after MDO ( P<0.05).@*CONCLUSION@#In the model test, the implantation of AC-MD complex can immediately rotate the mandible to the horizontal position and improve facial symmetry, and the residual condyle segment can be guided close to the articular fossa or the preset pseudoarticular position of the skull base after operation.

Objective To find out more optimal surgical approach for glioblastoma located in sensofimotor cortex and language area. Methods A respective review of 27 cases of glioblastomas located in sensorimotor and language area were operated, via the transsylvian-opercular approach, ineluding outcomes of microneurosurgery between January 2005 to December 2007. Results Among of 27 cases, tumors in 21 cases were covered by opereular cotex and were totally resected, tumors protruded into sylvian and wrapped around middle cerebral artery in 6 cases. 3 of them were totally removed, others were subtotally. Neurofunction of 26 cases were preserved of one were injuried. Conclusion Transsylvian-opercnlar approach for resection of glioblastomas located in subcortex of sensorimotor and language area is more optimal surgical approach, which not only ensure tumor resection with great degree, but preserve neurofunction well.
ABSTRACT
Objective To discuss the surgical strategy of parasagittal and falcial meningiomas in the middle 1/3 cortex area and raise resective rates of tumors and surgical effects.Methods The clinical,imaging and operative data of 74 cases of parasagittal and falcial meningiomas in the middle cortex area which underwent operation were reviewed and followed up.Results Of 74 tunors,67 were resected with Simpson Ⅱ grade,7 with Simpson Ⅲ,none of them with Simpson Ⅰ.Superior sagittal sinus and the vein of central suleus and feeders of cortex were reserved well.Severe brain injury was not occurred in 66 cases with tumors debulking(Simpson Ⅱ 61 cases,Simpson Ⅲ 5 cases),the neuro-functions of patients were normal or transient slight weakness of contralateral lower extremities postoperatively.Tumors of 8 cases were "turned over" and resected by piecemeal (Simpson Ⅱ 6 cases,Simpson Ⅲ 2 cases),weakness and paralysis of contralateral lower extremities occurred in 7 cases and 1 cases respectively after surgery.Followed-up ranged from 6 months to 4 years and 2 months,4 cases were lost to follow-up.Neuro-function of all cases with weakness of contralateral lower extremities recovered after one month.Muscle strength of the cases with paralysis of contralateral extremity recovered to grade Ⅳ 6 months later,no recurrence and death.Conclusion The measures,including piecemeal tumor reseeted mierosugically,good protection of the vein of central sulcus,excellent management of superior sagittal sinus,and avoiding damage to functional cerebral cortex during operations,are best ways for raising the tumor resection rate and nearo-function reserved.
ABSTRACT
Objective To collect the basic information on publications in Chinese Journal of Perinatal Medicine,and understand the current situation and set the goals for the future. Methods Information on all publications in this journal from 1998 to 2007 was collected.The distribution of all publications,Price Index and relative data were analyzed. Results There were 1368 publications altogether during the past 10 years.The first six kinds of papers were original articles(508,31.7%),short articles(258,18.9%),case reports(194,14.2%),reviews(122,8.9%),experimental studies(90,6.6%)and brief communications(83,14.2%).47.9% of all publications were from Beijing,Guangdong and Shanghai.The first three areas who had the most submissions were Beijing,Shandong and Guangdong in 2007.The citation frequency analysis showed that 708 publications were cited at 1east once and only two were cited over 80 times.53.4% of all cited publications were original articles and experimental studies. Conclusions Original articles and short articles are the two main types of publications in this journal,however original articles and experimental studies contributed to half of the publications being cited.Publications in this journal are focused in few areas and this might be related to the number of submissions.
ABSTRACT
<p><b>OBJECTIVE</b>To summarize the experience of minimally invasive treatment in 520 patients with intracranial aneurysms on a retrospective study.</p><p><b>METHODS</b>The measures used in the treatment of 520 patients were reviewed in terms of timing of surgery, induced-hypotensive anesthesia, brain protection combined with temporal occlusion of the feeding artery, external drainage of CSF, dynamic monitoring of intracranial pressure, blood flow velocity, serum osmolality and CT scanning, anti-vasospasm therapy as well as selected interventional endovascular embolization of aneurysms.</p><p><b>RESULTS</b>Of the 520 patients, 485 were treated with either direct clipping or endovascular embolization and 35 patients were treated non-surgically. In 449 patients undergoing direct clipping and 36 undergoing endovascular embolization, intraoperative rupture of aneurysm occurred in 27 (6.0%) and 0%, respectively. Death occurred in 13 (2.6%), hemiplegia in 8 (1.6%), and vegetative state in 2 (0.4%). The operative mortality of direct clipping was 3.8% in 210 patients before 1990 and 1.8% in 275 patients after 1990 (36 patients undergoing endovascular embolization, the operative mortality was 0%).</p><p><b>CONCLUSION</b>The outcome of patients with intacranial aneurysms can be markedly improved and the operative mortality can be lowered by minimally invasive treatment.</p>

Methods 428 cases of pregnancy complicated with heart disease were reviewed.54 cases were sur- gically corrected heart disease.Results:The incidence of pregnancy complicated with heart dis- ease,during January,1973 to December,1982 and January,1983 to December,1992,were 1.2% (254/21 221) and 0.9% (174/18 726)respectively.The ratio of rheumatic heart disease and congenital heart disease were 4:1 and 1:2 in two periods.There were 37 cases of heart failure and 4 cases of ma- ternal deaths occured.No heart failure and maternal death occured in cases with surgically corrected heart disease.In the two periods,the cesarean section rate were 16.9%(43/254),and 33.3% (58/74) ,P
ABSTRACT
Objective To valuate the effects of Balloon dilatation on shorting the duration of labour. Methods Vaginal-cervical Balloon dilatation were used to dilate the vaginal and cervix in 303 cases of pregnant women (67 cases in latent stage and 236 cases in active stage)in labor. At the same time,284 cases of pregnant women did not use the Balloon dilatation as control. Rusults The length of first stage,second stage and the length of labour were shorter when Balloon dilatation were used in latent phase than those in the control group(7.58,0.53 and 9.27 hours v.s 10.86,1.12 and 12.23 hours) P
