Objective: This study aimed to compare hearing and anatomical outcomes after ossicular chain reconstruction with titanium or hydroxyapatite prostheses. Methods:In this study, patients who underwent tympanoplasty and ossicular chain reconstruction with titanium or hydroxyapatite prostheses at a university hospital from January 2007 to February 2013 were retrospectively reviewed; they had a minimum follow-up period of 6 months. Patients were divided into 4 groups according to the type of prostheses. The surgical procedure, follow-up examinations, preoperative, and postoperative audiometry results were noted and evaluated for partial and total prostheses. The results were compared both for titanium and hydroxyapatite prostheses. Results:The study subjects included 51 patients. Titanium had better hearing results in partial prostheses (p<0.05), while the anatomical outcomes were similar. Nevertheless, both types had similar results in total prostheses (p>0.05). The extrusion rate was 5.8% for all patients. Conclusion

“…Durch das Fehlen von Makrophagen und Riesenzellen sowie die fehlenden Zeichen der Degradation am Implantat [57,58] empfahl sich Titan unter biologischen Gesichtspunkten als Ossikelersatzmaterial. Zwar war direkt am Material Osteoneogenese registrierbar, eine Osseointegration wurde aber weder tierexperimentell [59] noch an explantierten Prothesen im humanen Mittelohr [60] nachgewiesen. Schon vor diesen tierexperimentellen Prüfungen war Titan als passives Implantat in großen Fallzahlen mit guten Resultaten klinisch eingesetzt worden [61].…”

Besides eradication of chronic middle ear disease, the reconstruction of the sound conduction apparatus is a major goal of modern ear microsurgery. The material of choice in cases of partial ossicular replacement prosthesis is the autogenous ossicle. In the event of more extensive destruction of the ossicular chain diverse alloplastic materials, e. g. metals, ceramics, plastics or composits are used for total reconstruction. Their specialised role in conducting sound energy within a half-open implant bed sets high demands on the biocompatibility as well as the acoustic-mechanic properties of the prosthesis. Recently, sophisticated titanium middle ear implants allowing individual adaptation to anatomical variations are widely used for this procedure. However, despite modern developments, hearing restoration with passive implants often faces its limitations due to tubal-middle-ear dysfunction. Here, implantable hearing aids, successfully used in cases of sensorineural hearing loss, offer a promising alternative. This article reviews the actual state of affairs of passive and active middle ear implants.

“…Die negativen Resultate sind hauptsächlich auf eine nicht optimale biofunktionelle Integration im Mittelohr zurückzuführen. Als besonders Erfolg versprechendes Implantationsmaterial hat sich Titan erwiesen, welches in klinischen und tierexperimentellen Studien untersucht wurde [1,9,10,23,24,25,30,31]. Um die biologischen Eigenschaften von Titan noch weiter zu verbessern, sind auf der Basis von Titanoxidkeramik neue Implantatmaterialien mit unterschiedlichen Oberfächenbeschaffenheiten entwickelt worden [4,33].…”
