One of the hardest bandages to apply well is one for auricular hematomas. After drainage, how would you apply a bandage to prevent the re-accumulation of blood in the perichondrial space?
Traditionally, one can wedge xeroform gauze or a moistened ribbon (used for I&D’s) in the antihelical fold. Behind the ear, insert several layers of gauze, which have been slit half way to allow for easier molding around the ear. Anterior to the ear, apply several layers of gauze to complete the “ear sandwich”. Finally, secure the sandwich in place with an ACE wrap, which ends up being quite challenging because of the shape of the head.
