Trommelfellrekonstruktion mit Knorpel: Indikationen, Techniken und Ergebnisse

Autogenous cartilage-perichondrium-composite-grafts have become essential and well established transplant materials in reconstructive middle ear surgery. They have proven to be particularly appropriate for surgical situations which benefit from the bradytrophy and stiffness of the cartilage (adhesive otitis, retraction pockets, subtotal tympanic membrane defects, revision tympanoplasty). Of the numerous techniques available, the perichondrium-island technique and the palisade-cartilage technique are described in detail in this review, also regarding modifications and comments in the literature. Both methods show good functional and morphological results and should be chosen according to individual surgical requirements. The data of experimental investigations are involved in the decision which technique should be favored.
