正常与单侧唇裂口轮匝肌和上唇血管的应用解剖 总被引:2,自引:0,他引:2
目的:为婴儿单侧唇裂功能性修复提供解剖学基础。方法:4例正常成人新鲜头颈标本,在下颌下缘面动脉远心端内注入红色乳胶。5例正常婴儿、6例单侧唇(腭)裂婴儿标本,经福尔马林固定,从皮肤面和粘膜面解剖上唇口轮匝肌,在手术显微镜下观察口轮匝肌的形态及血管的分布。结果:口轮匝肌分深浅二层。深层肌肉呈水平方向,起自一侧口角的皮肤和粘膜,走向另一侧口角。浅层由上下两束肌纤维组成。单侧完全性唇裂标本显示患侧深层肌肉在裂隙处中断,止于红唇由厚转薄处。而浅层肌肉不仅中断,其附丽点亦发生错位,造成鼻小柱、鼻翼畸形。健侧深层肌肉在裂隙处中断,浅层肌纤维均附于鼻小柱基部,造成鼻小柱向健侧偏斜。正常上唇动脉起始部和走行都较恒定,本组未见解剖异常。唇裂标本显示,一侧动脉不能与对侧同名动脉吻合成弓,还造成异常走行。结论:对单侧完全性唇裂功能性修复,患侧皮下剥离要达到鼻翼外侧,把扭曲错位的浅层肌组织从鼻翼基部及鼻翼外侧的骨膜上进行分离,并按解剖形态进行复位。 相似文献

Surveillance studies have shown that cleft lip and palate is one of the commonest craniofacial anomalies, occurring in approximately 1 in 500 live births. Previous studies on craniofacial form in unilateral cleft lip/palate subjects have been carried out, but most attention has been focused on the deformity of the bony septum whereas the deformities of the nasal spine and cartilaginous component of the septum had received little attention. Our recent study was based on monitoring a very specific type of nasal septal deformity, type 6, and its relation to the unilateral cleft lip/palate disease. This type is very anteriorly located and refers to the cartilaginous part of the nasal septum and the inter-maxillary bone itself. Rhinoscopic view shows a typical, almost horizontal, unilateral groove at the nasal septum located very anteriorly. At the opposite septal side, but corresponding location, there is so called basal crest.The results of our study showed that the incidence of type 6 septal deformity was very high not only in unilateral cleft lip/palate children (80.6%) but also in their parents (58% in at least one of them). In contrast, in our previous study this type of septal deformity was seen in only 3.7% of non-unilateral cleft lip/palate children before puberty, rising to 7.4% in students and 9.4% in adults.In other words, perhaps we can expect the onset of unilateral cleft lip/palate in the offspring of parents who both have a type 6 septal deformity. Perhaps there is a gene responsible for the onset of both type 6 septal deformity and the cleft.If these clinical entities belong to the same gene, the cleft per se could perhaps disappear from the Earth in a near future owing to the gene therapy which will be able to eliminate it before the baby is born or even conceived. 相似文献

目的 研究Millard法(旋转推进法)和改良Tennison法(三角瓣法)治疗单侧完全性唇腭裂的疗效及对患者颌面形态的影响。 方法 根据治疗方法的不同,将本院收治的52例单侧完全性唇腭裂患者分为Millard治疗组和改良Tennison治疗组,每组26例。术后6个月,评价2组患者的临床疗效;并于手术治疗前后,采用照片测量法测量患儿的鼻部形态指标,包括Enw(内眦间距)、BAW(鼻部高度)、BADH(双侧鼻翼高度差)、CHW(口角间距)、CL(鼻小柱高度)、CW(鼻小柱宽度)、NBD(鼻背倾斜度)、CD(鼻小柱倾斜度),测量患儿的健侧和患侧唇高。 结果 治疗后,改良Tennison组的临床修复优良率为88.46%,高于Millard组(69.23%),P<0.05。改良Tennison组平均BAW、CL、CW均大于对照组,平均BADH、CD均小于对照组(P<0.05),改良Tennison组健侧-患侧唇高差小于Millard组(P<0.05)。 结论 改良Tennison法治疗单侧完全性唇腭裂的整体疗效优于Millard法,能较好地保持鼻部和唇部形态的对称性,更好地控制患者颌面形态,维持颜面美观的形态学机制,值得临床推广应用。 相似文献

The nasal cavity of the buffalo received its blood supply from the sphenopalatine and the external ethmoidal arteries; the former vessel chiefly supplied the respiratory portion of the nasal mucosa, while the latter was distributed to the olfactory region. The greater palatine artery supplied a palatonasal branch in the most extreme oral part of the nasal floor. The nasal vestibule received bronches from both the maxillary labial and infraorbital arteries. The arteries are of the muscular type and presented in addition ot the usual structure of their walls, thin-walled and thick-walled types. Stalked polsters are encountered in the branches of the arterial vessels having walls of the normal thickness. The appearance of the longitudinally arranged smooth muscle fibers found in the intime of some of the subepithelial small arteries and arterioles is suggestive of their epitheloid structure. 相似文献

Cleft lip and palate are the most common congenital malformations in humans. Using 43 staged human embryos and early fetuses ranging from the 4th to 12th week of development, we investigated the development of the lip and palate in order to provide the basic developmental concepts required for managing these anomalies. The lower lip appeared as bilateral mandibular arches at Carnegie stage 11, and these were completely merged at stage 15. The components of the upper lip, medial nasal prominence and maxillary process, appeared at stage 16, and completely merged at stage 20. The median palatine process appeared at stage 16, and the lateral palatine process, at stage 17. The palatine processes and the nasal septum started to fuse abruptly at stage 23, and from external observation seemed to be fused at the 9th week. However, complete fusion did not take place until the 12th week of development. The tongue was prominent at stage 16, showed differentiation of the muscular tissue at stage 21, and was located superior to the lateral palatine process before stage 23. These results may be used in understanding the different mechanisms present in the formation of various congenital anomalies in this region. 相似文献

In spite of its clinical importance in cleft palate, there are few detailed accounts of the blood supply of the soft palate and palatal muscles. A series of dissections was carried out to investigate the supply of the levator and tensor veli palatini muscles. Ten adult cadavers and 12 fetuses were used, all of which had been previously injected with a variety of media to outline the vascular tree. Conventional dissection was performed on the cadavers, and microsurgical instruments and a dissection microscope were utilized for fetal dissections. In 70% of dissections the m. levator veli palatini had a dual arterial supply, from the ascending palatine and ascending pharyngeal arteries. In the remainining cases the muscle was supplied by a single artery, either the ascending palatine or ascending pharyngeal. In 79% of dissections the tensor muscle had a dual supply from the accessory meningeal artery along with either the ascending palatine, ascending pharyngeal, or, in one case, the lesser palatine arteries. The results suggest that in careful surgical closure of the cleft soft palate the normal dual arterial supply would protect the tensor and levator muscles from vascular damage. In the minority of patients where only a single vessel supplies the levator, a radical intrapalatal dissection may jeopardize its vascularity. 相似文献
