Abstract

This report corresponds to an intervention in a patient with a bone lesion of the scalp using sequential techniques, use of dermal matrix, followed by negative pressure therapy. The case stems from a 58-year-old woman who suffered an avulsion of the scalp after being caught by an agricultural machine, so she is referred to the Hospital Regional de Alta especialidad de Ixtapaluca, for surgical management. Joint surgery with neurosurgery was performed where initially a trephination was performed in “honeycomb” which functions as a vascularized medium to place the dermal matrix substitute and maintain angiogenesis, After this, it was covered with an autologous graft taken from the thigh 0.25mm thick. To increase tissue survival and decrease the risk of infections due to the extent of the lesion, used negative pressure therapy (TNP) with continuous pressure at 125 mmHg for 12 days. This treatment presented a notable regeneration of damaged tissues and decreased intrahospital stay time to 20 days as well as an adequate tissue integration, high survival of the tissues that revitalized the affected area.
