The surgical treatment for congenital atresia of the external ear canal has a problematic aspect because of the dificulty of the surgery itself, for example, operative insult such as the facial nerve injury and postoperative problem such as re-stenosis and post-operative middle ear infection. We invented a new approach for this disease, and called it as the modified transmastoid approach. In this preliminary report we showed our two cases which were followed up for 1 year.
Our approach is available for not only avoiding the facial nerve injury in surgery but also for not occuring the post-operative middle ear infection and re-stenosis of the new external ear canal. The post-operative hearing acuities were also satisfactory.
