Results

No adverse events were observed during the all-subject period.
Patients with orbital defects had difficulty maintaining adhesion and could not complete the 6-month trial period. Patients with microtia completed the trial period, but it was still difficult to maintain adhesion, and the degree of satisfaction was low. Although there were individual differences in the degree of satisfaction among the areola and nipple patients, some patients had a high degree of satisfaction.
