Prior to Punch Biopsy surgical procedure:
How is the Punch Biopsy surgical procedure Performed?
The Punch Biopsy procedure is performed in the following manner:
- The skin is prepped with an alcohol wipe. The Punch Biopsy is usually a clean procedure, but not a sterile procedure. Thus, a sterile drape is used to keep the field clean, if sutures are used to close the defect
- The skin is anesthetized, usually with injected local anesthetic
- The correct size Punch Biopsy device is chosen based on the judgement of the surgeon
- The skin is stabilized by stretching under mild tension, by an assistant or the “off hand” of the surgeon
- The opening of the sharp cylinder is place at a typical area of the skin lesion or rash, then rotated in a circular fashion with mild downward pressure. Care is taken not to injure underlying tissues or structures. The punch device is removed
- A cylinder of skin has been cut free of the surrounding skin, and typically protrudes up, attached only by a little subcutaneous fat. The specimen is gently put in a bottle of formalin or other fixative, using the needle used for anesthesia, or a fine forceps
- There is generally little bleeding, which can be controlled with cautery, aluminum trichloride solution, or a few sutures
Where is the Procedure Performed?
The Punch Biopsy procedure is usually performed in a dermatology exam room, or surgical suite, or at a hospital bedside.
Who Performs the Procedure?
