concha alteration
Surgical modification of the ear's concha bowl during otoplasty to reduce prominence and improve ear positioning.
Full Definition
Concha alteration refers to surgical techniques used to modify the concha bowl (the deepest part of the outer ear) during otoplasty procedures. This modification typically involves reducing the size or changing the angle of the concha to decrease ear prominence and achieve more natural ear positioning against the head. Techniques include conchal excision, conchal scoring, or conchal setback sutures. The procedure is often performed in conjunction with antihelical fold creation to address prominent ears comprehensively. Proper concha alteration is crucial for achieving natural-appearing results and preventing over-correction that could create an unnatural pinned-back appearance.
Usage
Usage note: Specify the type of alteration technique used; avoid generic terms like 'ear pinning' in clinical documentation.
