Prevention of Acquired External Auditory Canal Restenosis using a Customized Earmold Stent

Abstract

External auditory canal (EAC) stenosis is an obstruction of the orifice of the ear canal, which may be congenital or acquired. EAC stenosis is a very rare disease that is difficult to treat and recurs frequently. However, there is no gold standard for maintaining patency of medical and surgical treatment of EAC stenosis. Although various methods have been reported, the progression of stenosis or restenosis remains a major problem. we report a case of effective prevention of restenosis after EAC stenosis surgery using a customized earmold stent.
