A novel method to accurately locate the reconstructed auricle

Abstract

Background: Congenital microtia is a common congenital disease in children, the cause of which is still unclear. At present, the main treatment for congenital microtia is ear reconstruction. Accurately locating of the reconstructed ear on the affected side before ear reconstruction surgery is difficult, while it is the key of successful operation. Our ear reconstruction team has developed a novel method to accurately locate the reconstructed auricle. This novel method has achieved good results in clinical practice.Methods: Thirty patients with unilateral ear reconstruction, who underwent auricle reconstruction using our invented auricle reconstruction positioning method in the Plastic Surgery Hospital of Chinese Academy of Medical Sciences from January 2020 to July 2021, were enrolled in this study.Results: Through Wilcoxon signed rank test, we found that there was no statistical difference between the mean distance from the highest point of the patient's normal ear to the central axis of the nose and that from the highest point of the reconstructed ear to the central axis of the nose (P>0.05). Meanwhile, there was no statistical difference between the mean distance from the lowest point of the patient's normal ear to the central axis of the nose and that from the lowest point of the reconstructed ear to the central axis of the nose (P>0.05).The satisfaction rate of patients and their families to the location of the reconstructed auricle was 100%. Conclusions:The novel method of locating the reconstructed auricle employs simple materials. The implementation process is easy, and the effect is significant. To a certain extent, it solves the difficulty of locating the reconstructed auricle in ear reconstruction operation. Although this method can only be applied to patients with unilateral microtia, we recommend it for locating the reconstructed auricle by every plastic surgeon.

Pathogenic Genes for Congenital Microtia: A Bioinformatics Analysis

“…C ongenital microtia is a common organ deformity in plastic surgery. 1 The main clinical manifestations are a deformity or absence of the external auricle, atresia of the external auditory canal, an underdeveloped middle ear, or one which is associated with hemifacial shortia and other organ malformations. 2 Congenital microtia is more common in male patients, and more than 70% of them are unilateral congenital microtia, especially right microtia.…”
