Non-Vascularized Autogenous Bone Grafts for Reconstruction of Maxillofacial Osseous Defects.

OBJECTIVE

To determine the outcomes of non-vascularized bone grafts for reconstruction of maxillofacial defects.

STUDY DESIGN

Case series.

PLACE AND DURATION OF STUDY

Department of Oral and Maxillofacial Surgery, Armed Forces Institute of Dentistry, Rawalpindi, from January 2013 to December 2015.

METHODOLOGY

Descriptive analyses of 30 patients, who underwent maxillofacial reconstruction with non-vascularized bone grafts, were conducted. The demographic information, diagnosis, and type of graft harvested to reconstruct the defect were statistically analyzed. Outcomes of reconstruction with non-vascularized bone grafts were analyzed in terms of mouth opening, success of dental rehabilitation, and postoperative complications, i.e. surgical site infection and hardware loosening.

RESULTS

A total of 30 patients ranging from 8 to 60 years (33.57 ±14.74 years) had maxillofacial defects reconstructed mostly due to gunshot injuries, followed by post-resection defects. Overall 15 cases (50%) were reconstructed with iliac crest cortico-cancellous bone graft, 11 cases (36.7%) with rib; while in four cases (13.3%), costochondral graft was used for reconstruction. In 26 cases (86.7%), graft was found to be successful. In three cases, re-operation for onlay bone graft was required to provide optimal dental rehabilitation; while in just one case, postoperative surgical site infection was observed.

CONCLUSION

Non-vascularized bone grafts provide a reasonable and effective modality for reconstruction of maxillofacial defects.
