A New Flap Technique for Reconstruction of Microtia and Congenital Aural Atresia

Atresiaplasty is still a challenge for otolaryngologist, although the operation technique has been modified several times over the past decades. This study describes a reliable flap technique for combining atresiaplasty with total auricular reconstruction by performing the total auricular reconstruction with the MEDPOR framework at the same time as the atresiaplasty for patients with microtia and congenital aural atresia. We performed a prospective study of the medical records of 18 consecutive patients with congenital aural atresia. All the patients had a Jahrsdoerfer grade of 6 or higher, and the mean age was 9.7 years. Atresiaplasty with the new flap technique was performed in 19 ears in our department from January 1, 2011, through July 31, 2013. Among the postoperative ears, 17 ears (89.5 %) had the excellent outcomes, without infections and stenosis. Only two ears (10.5 %) had postoperative stenosis and atresia after infection, respectively. There were no other complications. We concluded that the new flap technique combining atresiaplasty and total auricular reconstruction yielded satisfactory canal patency, low infection rates, and favorable cosmetic results, with acceptable rates of complications. This novel flap technique is a valuable option in the armamentarium of microtia and atresia surgeons.
