Otoplasty is the most common ear reshaping procedure for prominent ears. Known as ear pinning, it achieves its result by bending the ear cartilage back into a better position and stabilizing them with sutures. In the short term it is the sutures that maintain the new ear position and a loss of their tension or knot stability would be detrimental for the desired aesthetic result. In the long term (may months) it is the scar tissue that holds the reshaped cartilage and eventually the cartilage will lose its memory.

Mersilene is a synthetic polyester fiber that is completely non-resorbable. Because it is a braided suture it has great handling and knot tying features. It allows for precise and consistent suture tension which is of paramount importance when adjusting the amount cartilage bending at various points along the back of the ear.

Otoplasty Suture Extrusion Dr Barry Eppley IndianapolisOnce an otoplasty has satisfactorily healed and the patient is happy with the result in both shape and symmetry, there is only one potential long-term complication. Since the mersilene sutures are permanent and are right under the skin on the back of the ear, there is a lifelong risk of a suture reaction or extrusion. Like all suture knots that are right under the skin they may eventually work themselves through the original incison/scar line or surrounding skin. This presents as new onset ear pain with either a suture extrusion or a draining suture abscess.

Fortunately such otoplasty suture issues can be easily solved. The exposed suture must be removed. In some cases it can be simply pulled out. In other cases the knot must extracted under local anesthesia. Removal of the suture does not affect the otoplasty result.

The occurrence of long-term suture extrusion in otoplasty surgery is very low. But it can occur at any time over a patient’s lifetime. Given that many otoplasties are done in very young patients, it may not occur for decades. Just to prove that point I removed an extruding suture from an 82 year-old that had an otoplasty done in 1947!
