什么是错合畸形?错合畸形是由什么原因引起的?出现错合畸形怎样治疗呢?笔者就此问题采访了国内著名口腔整畸学专家、第四军医大学博士生导师段银忠教授。段教授说,错合畸形是指儿童在生长发育过程中,因遗传和疾病、口腔不良习惯、牙齿替换不正常等原因导致的牙齿、颌骨、颅面的畸形。反合(地包天)、上颌前突(暴牙)、开合(上下牙咬不住)等都属于错合畸形。 相似文献

目的 探讨舌侧直丝矫治技术治疗安氏Ⅲ类错牙合畸形的效果。方法 选择2010-10至2016-10舌侧直丝矫治的安氏Ⅲ类错牙合患者30例。全部患者治疗前后的X线头颅侧位片用测量软件分析,测量19个标志点,部分标志点参考了北京大学医学部、Steiner、Tweed、Coben等的研究。其中骨性测量6个,牙性测量8个,软组织测量3个,垂直测量2个。比较治疗前后指标的差异。结果 与矫治前相比,SNA角、ANB角、上下唇至审美平面距有统计学差异(P<0.01),上切牙唇倾度加大(U1-SN、U1-NA),下前牙舌倾度加大(L1-NB),覆盖(Overjet)治疗前(-1.76±0.29),治疗后(1.08±0.20),覆盖明显加大,从负值变为正值,前牙反牙合解除(P<0.01)。结论 舌侧矫治技术可成功矫正恒牙期安氏Ⅲ类错牙合畸形,使患者的牙颌面和软组织侧貌得到明显的改善。 相似文献

43例尿毒症性脑病的治疗体会 总被引:2,自引:0,他引:2
目的:回顾总结尿毒症性脑病43例的治疗体会。方法:分析我科收治的尿毒症性脑病患者采用血液透析、血液滤过,或在强化透析的基础上,增加血透、血滤次数,延长透析时间,用高通量透析器等治疗,同时配合有利于改善脑细胞代谢、增加脑血氧含量的药物,尽快使大脑复能和苏醒。结果:除2例患者放弃透析治疗,2例患者抢救无效死亡外,其余39例患者精神症状均消失及病情转轻。结论:对尿毒症并发脑病者,临床上应予以足够重视,早期发现,及时充分进行透析和对症治疗,可降低死亡率。 相似文献

One hundred and ten patients with hypospadias underwent excretory urography and micturating cysto-urethrography before surgical correction. Urographic studies revealed abnormalities in 50 patients (45%), mainly anomalies of ascent and rotation of the kidneys. None of these patients required corrective surgery. Voiding cysto-urethrography disclosed disease of the urinary tract in 65 of 110 patients (59%). Meatal stenosis was found in 38 patients and a rudimentary vagina or a prostatic utricle was revealed in 11 others. Vesico-ureteral reflux was present in 14 patients, seven of whom had meatal stenosis as well. Cystitis was found in eight and a stricture of the membraneous urethra in one patient. The voiding cysto-urethrogram is able to demonstrate functionally significant meatal stenosis, genital abnormalities and vesico-ureteral reflux. It can also serve as a useful baseline for comparison with postoperative studies. We therefore consider that it should be included in the preoperative work-up of every patient with hypospadias. Excretory urography, however, is perhaps indicated only in those with urinary tract infection, or in patients otherwise symptomatic. 相似文献

Complete duplication of the pituitary gland is an extremely rare condition which is associated with a wide range of anomalies. An incomplete duplication affecting only the anterior pituitary gland or the pituitary stalk has not been described so far. We report 2 such cases of partial duplication of the hypophysis and briefly review the literature. 相似文献

We report three cases with Herlyn-Werner-Wunderlich syndrome in adolescents and young female. The objective of this report was to describe the clinical presentation, ultrasound (US) and magnetic resonance imaging (MRI) findings of Herlyn-Werner-Wunderlich syndrome. The three patients were 12, 13 and 34 years old, respectively. The reason for admission and clinical symptoms varied between the 3 patients, including menstrual cramps, vaginal bleeding, and dull pain in the hypogastric region. Nevertheless, the sonographic and MRI findings of all three cases were typical for HWWS, including didelphys uterus, obstructed hemivagina, and ipsilateral renal agenesis. 相似文献
