Mandibular defect reconstruction with nonvascularized iliac crest bone graft.

CONTEXT

Reconstruction of mandibular defect is a challenge to the head and neck surgeon because of associated functional and esthetic problems. Our experience with the use of nonvascularized iliac crest bone graft is hereby reported.

AIM

The aim was to report our experience with the use of nonvascularized iliac crest bone for mandibular defect reconstruction at University College Hospital, Ibadan. Nigeria.

SETTINGS AND DESIGN

A retrospective descriptive study was performed.

MATERIALS AND METHODS

Cases of mandibular reconstruction with iliac crest bone graft between January 2001 and December 2007 were included in this study. Grafts were secured with either a stainless steel wire or a titanium plate. Preoperative diagnosis, postoperative follow-up records including investigations, diagnosis of graft infection and subsequent treatment modalities were extracted from the available records.

STATISTICAL ANALYSIS USED

Descriptive variables were analyzed with SPSS version 14.

RESULTS

A total of 47 patients had mandibular defect reconstruction with nonvascularized iliac crest block bone during the study period. Thirty-eight patients had graft secured with transosseous wire [NVIBw] while 9 had a titanium plate [NVIBp]. The male:female ratio was 26:21 while the mean age of the patients was 24.6±4.25 years. Ten patients (21.3%) developed persistent graft infection during the postoperative period. All cases of infection occurred in patients who had transosseous wiring and analysis showed that 60% of the infected grafts revealed mixed microbial isolates containing Klebsiela spp, Pseudomonas Aeurogenosa, and E coli. Six (60%) of the infected grafts were removed as a result of unabated infection while 4 (40%) were successfully treated by exploration and pus drainage.

CONCLUSIONS

Nonvascularized iliac crest bone graft provides an affordable and less technical choice for mandibular reconstruction with minimal complications in a resource-limited economy.
