Congenital microtia is a kind of congenital defect symptom of the ear, which refers to the severe hypoplasia of the auricle. Often accompanied by atresia of external auditory canal, middle ear deformity and maxillofacial deformity. At present, the best surgical method is skin expansion combined with autogenous costal cartilage scaffold transplantation for ear reconstruction. The operation was carried out in three stages. 1 stage is the implantation of skin expander behind the ear.
Two-stage autogenous costal cartilage ear bracket implantation and auricle reconstruction. The third stage is auricle reconstruction and repair. Using skin expander: the skin expander delays the expansion of the flap, thus making the blood supply of the flap more reliable and easier to survive. External ear reconstruction by skin expansion has the advantages of sufficient skin source and no scar left after operation.
Operation method: the silicone expansion bag was placed under the skin of auricle reconstruction site, and saline was injected into the expansion bag one week later to gradually expand the local skin. One month later, after the skin expansion was completed, the second stage operation, namely ear reconstruction, was performed. Otoplasty can be divided into costal cartilage otoplasty and bracket otoplasty according to different materials. The third step is tragus and conchoplasty.
The above is about microtia. I hope it helps you. I wish you a perfect ear as soon as possible.
