This study war performed to investigate the posterior ear canal wall reconstruction with a compound cartilage - titanium mesh in canal wall down tympanoplasty and revision surgery for open mastoids. Defects of the posterior external ear canal resulting from canal wall down technique or present in revision surgery were eliminated by a reconstruction using a composite titanium-cartilage mesh. The mesh was covered with conchal cartilage and attached to the remnants if the posterior wall or mastoid bone at two corners using 3-mm titanium screws. All patients maintained a normal contour of the external ear canal without depression, extrusion or infection. There were no failures based on short-term postoperative controls. However 2 patients has to be revised due to incomplete coverage of the titanium mesh. This study reveals that the reconstruction of posterior ear canal wall defects with titanium meshs is a reliable method for preserving the morphology of the external ear canal and an alternative option besides other reconstructive or obliterative techniques.
