Introduction:
Reports on the outcomes of cranioplasty after combat-related injuries are relatively rare in the current literature. We present our results on the reconstruction of cranial defects resulting from injuries sustained in combat, comparing outcomes using autologous (iliac bone) grafts or (acrylate) allografts, and analysis of other factors that may influence the final outcome.
Material And Methods:
The study comprised 207 patients with cranial defects resulting from combat-related injuries, repaired with autografts or allografts. The final outcome was defined at least 5 years postoperatively on the basis of cosmetic restoration and the existence of complications as successful (acceptable cosmetic restoration + absence of complications) or unsuccessful (poor cosmetic restoration or acceptable cosmetic restoration + complications).
Results:
Successful outcomes were achieved in 83.6% of patients; there was no operative mortality. There were 25 instances of complications: postoperative infection (n = 15, allograft (7/53), autograft (8/154)), autograft resorption (n = 8), and in two cases, graft luxation. Poor cosmetic restoration was noted in 9 (4.3%) patients who had received an autograft.
Conclusions:
Thin and poorly vascularized skin, a surface area of the defect larger than 88 cm2, previous local infection and communication with paranasal cavities significantly influenced outcomes after combat-related cranioplasty, the final three being independent predictors of an unsuccessful outcome.
