The full creation of an ear requires 2 reconstruction stages. In the second stage of reconstruction, the cartilaginous framework placed at first stage is separated from the head creating an auriculocephalic sulcus. Then a piece of rib cartilage is placed in the sulcus to maintain this separation and is covered with tissue that allows the integration of a full-thickness skin graft.
A descriptive study based on the pre and postoperative medical records and photographic archives of patients diagnosed with microtia
who underwent separation of the cartilaginous framework from February 2010 to July 2015 in the Plastic and Reconstructive Surgery Department at Hospital General Dr. Manuel Gea González.
Fifty-four patients met the selection criteria. The temporoparietal fascial flap
was performed on 85% (n = 46), and 8 cases with random occipito-temporal fascial flap in association to a dermal regeneration template
. The average time at the operating room was 177 minutes in patients with temporoparietal fascial flap
versus 84.5 minutes in dermal regeneration template
. The complication rate was 25.9% (n = 14), being similar rate with both techniques.
Coverage with dermal regeneration template
and random occipito-temporal fascia flap as an alternative use instead of temporoparietal fascial flaps, offers good postoperative results, lower operating times, and similar rate of complications, with the advantage of producing no visible scars and reserve the temporoparietal fascial flap
for possible exposure of the cartilaginous framework.
