The Research Of Secondary Unilateral Cleft Lip Nasal Deformity Classification And Surgical Methods

Oral and facial cleft lip is the most common congenital malformations, often involving the skin, muscle, mucosa, bone and cartilage, the prevalence rate is 1.8:1000, more men than women, and there is an upward trend. Repair of cleft lip,surgery is the only means and important. As a result of surgical technique, surgical time, as well as local tissue factors such as abnormal development, often to varying degrees of secondary cleft lip and nasal deformity.Common secondary deformities of the main upper lip are the scar is too wide or hollow, the thickness of the red lip is asymmetrical, the upper lip is too long,or too tight,lip margin irregular, uneven arch lip, alar base displacement, the nose bottom width different, side alar collapse, nasal columella short or shift to the contralateral, such as tip collapse. Unilateral cleft lip nasal deformities after the repairation is almost impossible to avoid, most deformities need restoration again.Cleft lip nasal deformities and diverse clinical manifestations, it led to a variety of repair methods. Cleft lip nasal deformities methods had been controversial, so far without any definite conclusion.Starting from the last century, there are scholars classified cleft lip nasal deformities in order to facilitate an assessment of the effect. Gradually resumed after a number of research methods will be classified nasolabial deformities on the one hand, in order to better assess the after effects of cleft lip; on the other hand, in order to better carry out the second time restoration. Took place according to their location and the performance of classification, can occur in isolation, there can also be combined. Performance for the upper lip scar is too wide or hollow, red lip asymmetric thickness, the upper lip is too long, too tight upper lip, red lip margin irregular, uneven, such as bow lips. The performance of nasal deformities are the alar base of the shift, the nose bottom width different,side alar collapse, nasal columella short and shift to the contralateral, such as tip collapse. But in most cases, even more biased in favor of the theory of histological studies, for clinical help need to be proved.This issue through the study of the cases, according to nasal stents and the orbicularis oris muscle abnormalities associated with a natural deformity, the treatment of clinical symptoms of a combination of design and be classified as a simple correction of secondary cleft lip deformity of an integrated approach.Materials and Methods: In this experiment, by Choice of unilateral cleft lip by the same technique to implement a second operation for the patients studied,measureing the red lips, white lips and nose data obtained. we will know the nasolabial deformities come to focus on aspects of performance, and then classify, and then choose suitable symptomatic surgical methods. Results: According to the location of occurrence of lip deformity and surgical approach to the performance of lip deformities fall into three categories namely, the red lip deformities, white lip deformities and upper lip deformities too loose or too tight. Abnormal nasal ring stent on this basis will be divided into two types that put that needs to be done alar margin incision to reconstruct the nose into a particular class, while others classified as mildly abnormal performance of the other.On the basis of the existence of regular clinical manifestations and the inevitable histopathology relationship,Re-combinat these two parts fall into three categories. Classâ… deformities: normal nasal form in the nasal columella is not short, the location is middle or slightly skewed, symmetric or only mild nasal shift collapse, alar base of the mildly lower; upper lip height and width of the normal. Abnormal performance of the Department is focused on the red lips such as: not significant lip beads, irregular bow lip bows, groove-like depression,lip summit are exposed to high,and the asymmetrical dry lips, for just such deformities or illnesses to deal with lip deformities can; Class II deformities: normal width of the upper lip, significantly less length of the whit lip of the normal side than Class I,nasal columella with deflection and short, the collapse of the alar base displacement, nasal bottom of the deformity side is greater than the contralateral,and obviously deformitied red lips of those.The main use of such abnormal cartilage are the macroptilium suspension of nasal alar and reduction of the orbicularis oris muscle ways to completely solve the pathological factors;Class III deformities: less height of upper lip,tight tissure of upper lip,lower lips are wider than upper lips; Nasal columell obviously deflected,and the nasal alar collapse obviously. Focusing on the use of a one-time transfer lip fragment repair the two parts of nasolabial deformities. Clinical classification based on the above-mentioned methods and focus on the implementation of operation 25 cases of surgery, postoperative observation changed significantly, more satisfied patients.So far, the study of cleft lip deformities and surgical methods of increasingly detailed and specific, but cleft lip nasolabial deformity based on the type and method of operation for less. In this study clinical cases of the statistics, come to focus on the performance of cleft lip nasolabial deformities which to classify, and then in the clinical classification based on the selection of appropriate surgical methods, postoperative results were satisfactory. Therefore, concluded that the study of cleft lip nasolabial deformities classification is meaningful, perhaps for the good second time retoration of cleft lip nasolabial deformities provide some help.
