Purpose of the study. To increase the effectiveness of rehabilitation of patients with acquired bone defects of the mandible with the help of rib free non-vascularized autografts.
Materials and methods. In the maxillofacial department of Municipal non-profit enterprise
«City Clinical Hospital for Emergency and Medical Care, Zaporizhyzhya» Council 41 patients were treated, who underwent surgical treatment to replace the acquired bone defects of the mandible with rib free autografts on the basis of the clinic of maxillofacial surgery of the State Institution SE «Zaporizhzhya Medical Academy of Postgraduate Education of the Ministry of Health of Ukraine» 2015–2019. Most patients were of working age: from 21 to 60 years. In general, the age composition of patients was almost identical, which allowed us to assume that all studies were conducted under the same conditions and in a standard sample. Depending on etiology, surgery – replacement of mandibular defects, performed simultaneously or across a long time period.
Results. Improved technique of mandibular bone grafting by free rib autograft due to the expansion of the technical possibility to reliably fix bone fragments with titanium plates and screws, as well as tight installation of the autograft in the bone defect and create, consequently, favorable conditions for a pseudo-temporal-mandibular joint formation. The own technique of preparation and formation of a costal autograft is offered. For 15 years, no complications were detected and no rejection of freely transplanted costal autografts was observed.
Conclusions. The use of reliable fixation of bone fragments ensures the formation of callus and prevents autograft rejection. The proposed method of preparation of a costal autograft with a fragment of cartilage, allows to achieve reliably forming a pseudo-temporal-mandibular joint.
