Wide Cortical Drilling and Anterior-Based Periosteal Flap Reconstruction: Innovative Approach for Acquired Stenosis of External Auditory Canal

In patients with acquired stenosis of external auditory canal, traditional canaloplasty surgery using skin graft may be performed when symptoms are severe or persistent. However, the risk of restenosis during follow-up period remains a main concern for surgeons. Herein, we present a novel surgical technique using wide cortical bone drilling and reconstruction using the anterior-based periosteal flap. We also report the preliminary results of case series using this surgical technique comparing it with the traditional method.
