Background:
It has been suggested that preservation of nonviable cranial bone is possible in some selected cases in the absence of infection.
Methods:
A series of ten male patients, mean age 29 +/- 7 with severe electrical scalp burns and nonviable cranial bone were managed conservatively. The patients were treated initially by soft-tissue debridement until the wound presented viable, clean margins. At 22 +/- 6 days after the burn, multiple burr holes were made in the nonviable bone, and the defect immediately covered with a well-vascularized scalp flap. Each patient's progress was documented during the hospital stay and during the follow-up for at least one year.
Results:
The multiple burr holes filled with fibrous tissue and the contour of the skull was maintained in all 10 patients making the need of a secondary cranioplasty unnecessary. No postoperative infection, osteomyelitis, or cranial bone sequestration occurred.
Conclusions:
Even with moderately delayed management of contaminated electrical burns, partial excision of the necrotic bone with burr holes and flap coverage appears to be adequate.

01:22Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...
