Abstract:
Objective:To explore a 1∶1 2D printing method of rib cartilage based on CT scanning in assisting ear framework fabrication for auricular reconstruction.
Methods:From January 2016 to January 2017, 73 cases of microtia aging from 5 to 7 referred to our department. A 1∶1 2D printing of rib cartilage based on CT scanning was applied in preoperative assessment and measurments of bilateral sixth, seventh and eighth costal cartilage were completed before the surgery. Personalized rib cartilage ear framework fabrication was determined by the measurements.
Results:Among the 73 cases, 58 cases received auricular reconstruction successfully. There were 15 patients whose rib cartilages did not meet the requirements and postponed the surgery. The patients who underwent auricular reconstruction were followed up for 6 to 12 months (average, 9 months). During the follow-up, 52 cases had satisfactory outcomes in size, shape, symmetry and details. No deformation of reconstructed ears or chest wall was found during the follow-up.
Conclusions:The 1∶1 2D printing based on CT scanning is a simple and timesaving way to evaluate the rib cartilage. It can be beneficial to save the amount of cartilage and improve the personalized ear framework fabrication.
