Secondary surgery for the unsatisfactory auricle after auricular reconstruction

Abstract

ObjectivesComplications, including framework exposure, infections, and reconstructed auricle deformation, may occur after auricular reconstruction. However, reports on surgical methods for cases with unsatisfactory outcomes after auricular reconstruction using an autologous costal cartilage are insufficient. Herein, we summarized retreatment casesfor poor ear morphology in patients who had undergone auricular reconstruction in our department for 5 years and discussed other techniques. MethodsBetween September 2014 and September 2019, 24 ears of 24 patients with poor morphology, unsatisfactory macroscopic characteristics and anatomical structures, and unsatisfactory outcomes of local repair after auricular reconstructive surgery were treated. Patients were divided into the following three groups: type 1 (9 ears), with intact and sufficient hairless skin in the mastoid region behind the reconstructed ear; type 2 (7 ears), with intact, but insufficient, hairless skin in the mastoid region behind the reconstructed ear; and type 3 (8 ears), with hairless skin in the mastoid region behind the reconstructed ear with impaired skin integrity. ResultsTwenty-two (91.6%) patients successfully completed the surgical treatment and recovered well; one experienced delayed wound healing and another developed hypertrophic scarring at the incision site at 3 months postoperatively. All patients were followed for 0.5–4 (mean, 2.8) years. The macrostructure of the reconstructed ear post-revision was stable and significantly improved in terms of morphology and structure. ConclusionsIn patients with unsatisfactory outcomes after auricular reconstruction, the appropriate technique for the revision surgery should consider the local soft tissue conditions of the reconstructed ear to obtain satisfactory results.
