In treating congenital microtia and atresia, we conduct simultaneous external canal plasty, tympanoplasty, and auricle elevation with plastic surgeons about 6 months after auricleplasty by only plastic surgeons. The results are good both cosmetically and functionally.
We report 13 cases in which hearing did not improve satisfactorily after surgery using postoperative high-resolution computed tomography (HRCT) of the temporal bone.
Lateral healing was seen in 9 (69%), new bone proliferation in 3 (23%), malpositioning of a cartilage block in 2 (15%), and both lateral healing and malpositioning of a cartilage block in 1 (7.6%).
