Evaluation Of Treatment Outcome In Unilateral Cleft Lip Patients By Three-dimensional Capture: A New Approach's Study

Congenital cleft lip is one of the most common human birth defects, one seriously affect the aesthetics as well as other functions, such as swallowing, sucking, language, and can result in children with psychological barrier. According to statistics, China's current annual increase of about 14,000 more than in children with unilateral cleft lip cases whose number is large. Unilateral cleft lip repair surgery now means more, such as the rotation-advancement repair, Tennison- Randall triangular flap repair, a straight-line repair, etc. However, the advantages and disadvantages of different methods have been varied. The urgent need for an objective, feasible and good methods for evaluation is demanded which assess the effect of postoperative treatment and guide clinical practice.In this study, three-dimensional scanner for facial scans in children with unilateral cleft lip, access to children pre-and postoperative facial shape data, and then import it into reverse engineering software Geomagic Studio 10.0 in the reconstruction and data measurement, as a basis for to establish a method of evaluation of results of operations, and try this method of evaluation of the most common surgical methods of rotation-advancement repair (Millard's method) of the repairing effect. The results are as follows:1. Using three-dimensional scanner of one cases of unilateral cleft lip (â…¢degree) in children with facial scans obtained before and after surgery in children with facial morphology data, import it into reverse engineering software Geomagic Studio 10.0 in the reconstruction and measured data. Results: This method can quickly and accurately complete the reconstruction in children with facial morphology, and can be completed in the software calibration of facial landmarks, the distance between the established landmarks measurements, proved to be as a basis for the establishment of a new evaluation of unilateral effect of method of cleft lip repair surgery.2. Stresses the use of three-dimensional scanner with reverse engineering software to children with facial data obtained, compared to manual application of methods to measure anesthesia in children after the success of facial data. The results showed that: the two was no significant difference between the measured values (P> 0.10), thus proving the accuracy of the data obtained is reliable and can meet the need for evaluation of results of operations.3. Use this method of evaluation of Millard's method of unilateral cleft lip repair surgery and found that: Millard's method is useful for repairing unilateral cleft lip in recovering nasal floor, the Cupid'bow and in remedying the deviation of columella except for a little shortage of the lip height and columella length of the operated side, which is corresponded with many years of clinical experience. The conclusion supports the feasibility of this new method for evaluating the outcome of clinical practice.Through research we found that three-dimensional scanner with reverse engineering software can quickly and accurately complete the reconstruction in children with facial morphology, and can be completed in the software calibration of facial landmarks, the established measurement of the distance between landmarks, and as a basis for the establishment of a new evaluation of unilateral cleft lip repair surgery results-based approach, and the method is objective, accurate, feasible, worthy of promotion.
