The majority of moles and blemishes do not to be removed, however, it they are suspicious for cancer, a dermatologist may advise removal for further testing.
Moles or blemishes that are of cosmetic concern can also be removed. In both situations it is important to minimise scarring and to maximise cosmetic outcome. Your treating dermatologist will advise you on the types of lesions you have, and which procedure will give you the best cosmetic outcome.
This surgical technique is conducted without sutures. We perform shaves with either a traditional blade method, or with electrocautery. A shave excision is a simple yet effective procedure that can give excellent results. For patients with darker complexion, laser removal is a more precise method, and will minimise scarring and post surgical pigmentation.
This procedure is usually performed for deeper moles. In the majority of cases we use deep dissolving sutures in addition to skin sutures to minimise scarring.
Procedural dermatologist have additional training to perform more advanced skin surgery.
Laser surgery can be used to treat lesions such as moles, age warts (seb keratoses), and birthmarks. Lasers function as precision tools to ablate tissue to a specified plane, minimising damage to deeper and surrounding tissue. Erbium ablative laser can be as accurate as 5/1000 of a millimetre.
For birth marks, vascular lasers such as the Pulse dye laser or Erbium Yag laser can be effective. Several treatment sessions are usually required.
(As Practice policy, we do not treat children under the age of 8 with laser procedures. The Royal Children’s Hospital has laser facilities to manage birth marks in children.)
