The use of osteointegrated implants in plastic surgery. Ear reconstruction

The authors present the case of a 14-year-old patient suffering from first branchial arch syndrome with agenesia of the auricle in which the auricle was reconstructed using osteointegrated implants. The patient had previously undergone numerous attempts at reconstruction using traditional methods, all of which had failed. In order to ensure an accurate preoperative evaluation, the patient was studied using CT with a standard technique and three-dimensional image reconstruction for a qualitative and quantitative evaluation of bone thickness so as to allow the optimal positioning of fixtures. This test also revealed the existence and good degree of development of the middle and internal ear. The Authors then proceeded to implant 4 titanium fixtures into the mastoid process of the temporal bone, three of which were used for fixing the auricle prosthesis and one for the insertion of a bone anchored hearing aid. The epithesis, in soft silicon, was modelled to match the contralateral ear with excellent aesthetic results.
