Mandibular reconstruction with the THORP condylar prosthesis after hemimandibulectomy

Abstract

The subject of this paper is the evaluation of the advantages pertaining to the THORP (titanium hollow screw reconstruction plate) condylar prosthesis for reconstruction after hemimandibulectomy and exarticulation. The THORP condylar prosthesis is three-dimensionally adjustable, enabling the intraoperative meticulous functional adaptation of the condyle. Various designs of the condyle make it possible to achieve optimal congruency between the articular fossa and condyle. The anchorage of the prosthesis to the stump of the mandible is achieved with perforated hollow-screws rigidly fixed to the plate, thus producing optimal functional stability. The long-term follow-up of eleven cases, reconstructed with this system, confirmed the correct guidance and functional efficiency of this type of condylar prosthesis.
