Surgery is a medical specialty that uses operative manual and instrumental techniques on a patient to investigate and/or treat a pathological condition such as a disease or injury, to help improve bodily function or appearance. Surgeries on skin are performed to treat burns, injuries, wounds, or for cosmetic reasons. Procedures like skin grafting and skin transplantation involves pitching and cutting away skin from the donor section and attaching it to the recipient section of the body. This book studies various types of skin surgeries such as eschar, barbed suture, surgical staple, needle aspiration biopsy, and surgical margin.
