The Observation Of The Orbicularis Oris And The Postoperative Evaluation Of Unilateral Harelip With The High Frequency Ultrasound

Objection:To realize the feasibility of which the observation of the orbicularis oris with the high frequency ultrasound and explore it’s application in the postoperative evaluation of unilateral harelipMethods:Using the high frequency ultrasound to observe the upper lip orbicularis oris of168normally adults and36adult postoperative patients of unilateral harelip. Scan the upper lip orbicularis oris and observe the shape and structure of the orbicularis oris in ultrasonogram. According to the gross anatomy and microscopic anatomy of human specimens, measure the orbicularis oris’thickness; and then measure the36adult postoperative patients’cicatrix width and thickness of orbicularis oris, then analyze the relation with6indexs of upper lip deformity. Analyze the the relation between plerosis effect of orbicularis oris and hand evaluation of postoperative patients.Results:The upper lip organizations are different between the normal youth and unilateral cleft lip postoperative youth in ultrasonogram: the upper lip organizations are divided into five layers from shallow to deep in the normal youth. The orbicularis oris of postoperative patients is interrupt and malposition. The thickness of the men and women’s orbicularis oris are the same; the shallow layer shows a "among low, both sides high" form and it will become thickened in pouted state. The postoperative patients’shallow layer are thinner than the normal youth.6indexs of upper lip deformity and cicatrix width are statistically significant correlation; It is associated with better orbicularis oris plerosis, smaller cicatrix width and good hand evaluation of postoperative patients.Conclusion:Using the Ultrasound technology to observe the orbicularis oris can obtain a clear Dimensional Ultrasonographic of the anatomical structure, it not only can be used to observe the plerosis effect of orbicularis oris, but also used to evaluate the operation effect. The orbicularis oris with cicatrix will impact the growth of the shallow layer but not the deep layer of the orbicularis oris.
