[Abstract]:Objective: to optimize the location of auricle reconstruction and the design of special ear stent for patients with craniofacial asymmetry by digital technique, and to find a method to improve the effect of postoperative symmetry. Object and method: 1. Participants were admitted to our group from September 2014 to March 2015 for unilateral microauricular malformation with craniomaxillofacial malformation. The 50 patients who met the criteria were 36 males and 14 females, aged from 5 to 20 years, with an average age of 8.28 years. Divided into study group, control group two groups, each group of 25 people. 2. Methods (1) the auricle and craniofacial images of the patients in the study group were scanned by three-dimensional radiography, and the digital models of auricle and craniofacial were established by scanning data. Digital technique was used to locate the reconstructed auricle and obtain the shape and correction parameters of the scaffold. (2) the patients in the study group were scanned by spiral CT scanning, and the patients in the study group were scanned with costal cartilage. The digital model of costal cartilage was obtained by CT 3D reconstruction technique, and the morphological parameters of costal cartilage were measured to estimate the amount of costal cartilage tissue. (3) according to the above auricle location information, the parameters and the amount of costal cartilage tissue were measured. The patients in the study group underwent auricle reconstruction with individualized auricular stent and dilated auricle reconstruction. (4) the patients in the study group and the control group were followed up for one month after operation, followed up by the operator, the third party plastic surgeon, the family members, the third party plastic surgeon, and the control group. The third party family evaluated the symmetry of the positive view, the side view and the back view of the reconstructed ear independently (including the third party plastic surgeon and the third party family member as the blind evaluation), expressed as excellent, good and bad, and carried out the K (Kappa) test on the symmetry excellent and good rate. Statistical analysis was carried out. The result is 1: 1. The digital model of skull and auricle established by three-dimensional photography is clear in shape and realistic in three-dimensional sense. 2. In the digitized 3D model, there is a gap between the healthy ear image and the affected craniofacial image after the mirror image operation and the interactive comparative positioning between the craniofacial and the cranial surface of the affected side. 3. The localization information can be calibrated by software after the good symmetry of the bilateral auricles is obtained by software operation in the digital 3D model. The morphological parameters and correction parameters of auricle were measured in the digital model. The results of follow-up for one month after operation showed that the score of the study group was higher than that of the control group, and the scores of the third party plastic surgeon, the family member and the third party family member were higher than those of the control group. Conclusion 1. A good auricle and craniofacial digital model can be established by three-dimensional photography to guide clinical operation. 2. Through the analysis of digital model, the location information of reconstructed auricle can be obtained, and the morphological parameters and correction parameters needed for the design of auricle scaffold can be obtained. Under the guidance of the above location information and parameter information, the effect of auricle reconstruction in patients with craniomaxillofacial asymmetry was better than that obtained by conventional methods.
