Removal of foreign body - subcutaneous (e.g. splinter) Dermatology Surgery
This is a minor procedure to take out an object that is stuck just under the skin.
Overview
This is a minor procedure to take out an object that is stuck just under the skin. Subcutaneous means it is beneath the surface layer of the skin. The clinician may numb the area, make a small opening if needed, and remove the object with tools like tweezers or a small blade. The wound is then cleaned, and the skin may be closed with adhesive strips or stitches if needed.
Also known as: Splinter removal, Subcutaneous foreign body removal, Skin foreign body removal

Common questions and expert answers about this procedure
How is a subcutaneous splinter or foreign body removed?
How is a subcutaneous splinter or foreign body removed?

Imaging is not always needed. X-rays can show metal and most glass. Ultrasound can help find wood or plastic and guide removal when the object is hard to locate.
Do I need antibiotics?

Antibiotics are not routine for clean, uncomplicated removals. They may be used when the wound is contaminated, infected, or high risk based on location and history.
Do I need a tetanus shot?

It depends on your vaccine history and the type of wound. Clinicians follow CDC guidance for when to give tetanus shots after injuries.
