Background: The ear is the most complex topographic feature of the face. (even though it is technically not on the face. It is a seemingly convoluted mix of ridges and valleys that have different variations amongst people which makes the ear almost as person specific as a fingerprint.
The most visually evident feature of the ear is the outer helical rim and its continuation into the earlobe. Because it is the outer perimeter of the ear a smooth shape to it is desired regardless of the overall size of the ear. While the outer edge of the rim needs to be smooth this actually applies to its inner edge as well. Such a smooth inner edge of the helix can develop a prominence or bulge which is most commonly seen in the superior helical rim. This is known as helical lidding and represents a bump or overgrowth of cartilage. It is the equivalent of Wharton’s tubercle which is a cartilage bump on the outer helical rim edge.
Case Study: This male was to undergo an ear reshaping procedure to set his ear back due to an overall prominence. He asked about getting rid of this extra segment on the upper ear that protruded down on just his right ear.
At the completion of the main otoplasty procedure an incision was made right along the edge of the helical lidding. This exposed the excess cartilage, which was the culprit, and it was removed along with a few millimeters of excess skin.
While helical lidding is a minor ear deformity its disruption of the smooth helical rim is a distraction from the normal shape of the ear. It is easily removed with no visible scarring and can be done with an otoplasty or as a stand alone ear reshaping procedure under local anesthesia.
1) Helical lidding refers to an overhang of the inner rim of the outer helical rim most commonly seen at the superior helix.
2) Helical lidding is the result of a cartilage prominence that can be reduced with the excessive skin by direct excision.
3) Helical lidding correction can be safely done concurrently with almost any other type of otoplasty procedure.
