Abstract
A procedure known as tangential excision has recently been stated to enhance the healing of burns; to investigate the validity of this technique, experiments have been made using the guinea-pig as the test subject. It was found that, provided that certain criteria were met, this procedure allowed early healing with reduced tissue destruction. The operation is best performed 5 days after burning, when the least tissue needs to be excised for the successful take of skin-grafts. Excision must be down to the level of punctate bleeding; more superficial excision with or without grafting does not influence healing; deeper excision results in unnecessary tissue loss. Grafts are seen to take on tissue that would otherwise be regarded as non-viable. This tissue rapidly becomes re-vascularized and is either resorbed, or provides a scaffold for new tissue formation.
