Can you explain what the difference is between an incisionless ear surgery and an open ear surgery?
An otoplasty done without incisions is actually done through a series of very tiny incisions, each less than 1 mm. They are just large enough to admit the suture needle for the sutures needed to shape the ear. In the more standard technique an incision is made in the crease behind the ear. The sutures are placed through this opening, and the cartilage can be trimmed an molded. I think the open approach is more complete in most ears. There are few in which the incisionless approach will work.
