Background
Multiple modalities to manage scalp and underlying skull defect due to high-voltage electrical burns have been discussed. We aimed to describe our experience and to propose an algorithm for the management of skull injury which could be helpful in decision-making.
Methods
A retrospective study of patients who sustained electrical burns to the head from May 2007 to April 2012 was carried out. Sex, age, size of scalp defect, and method of reconstruction and management were analyzed.
Results
Thirteen patients were identified. Out of 13, 11 patients had scalp defects which were covered using local scalp flap. Free latissimus dorsi (LD) muscle flap and pedicle trapezius flap were used in two patients. The largest defect covered with local scalp flap was the size of 80 cm2. Free LD flap was used to cover a defect of 144 cm2. Of the nine patients who presented early (immediately after injury), seven required debridement of the outer table and the other two patients required full-thickness excision of the skull. The remaining four patients who presented late (after 3 months) were found to have osteomyelitic segments which required full thickness excision of the skull.
Conclusions
Most of the soft tissue defects of the scalp due to high-voltage electrical burns can be managed with local scalp flaps. However, if the local tissue is injured or not sufficient to close the defect, then free flap should be considered. In management of calvarium injury, the emphasis should be debridement of necrotic bone to provide infection-free site followed by soft tissue cover.
Level of Evidence: Level IV, therapeutic study.
