Newborn ear deformities not only affect the aesthetics, but also have a negative impact on the baby’s psychological development. Newborn ear deformities can be broadly classified into four categories: auricular deformity, external auditory canal deformity, middle ear deformity, and inner ear deformity. Correction of newborn ear deformities requires conservative or surgical treatment depending on the specific condition and cause. The ears can be surgically removed at any time, and the ears can be corrected by wearing an ear widening device within three months of birth. External auditory canal malformation and middle ear malformation should be treated mainly by surgery. Inner ear deformities should be treated with hearing aids or cochlear implants depending on the hearing level of the newborn and other examination results. The best age for treatment and correction of auricular deformities is between the seventh and 21st day of life. If the auricular deformity does not improve, the baby should receive non-invasive correction as soon as possible, usually with a treatment period of two weeks and a cure rate of 95%. can undergo non-invasive correction, and the treatment cycle will be extended to a period of four to six weeks. When the newborn is older than 42 days, the cartilage in the ear is relatively stiff and non-invasive correction will be less effective. If a newborn is found to have an ear deformity, early medical attention and treatment is recommended.
