[Total reconstruction of the posterior wall of the external ear canal with allogenic rib cartilage. Technique and results].

Middle-ear reconstruction using a closed surgical technique has the same surgical stages as in combined-approach tympanoplasty. The only special feature is the reconstruction of the posterior canal wall and scutum, an essential step. This reconstruction process is carried out with allogenic costal cartilage affixed to two deep bony slots with fibrin glue. In 90% of cases surgery is done in two stages.
