A few surgical option of mole removal is available.
This forms an alternative to the laser cautery. This uses the electric current to burn the mole. The current used is usually very low. The current is set to a level such that it only reach the required layer of the outer skin so as to avoid the possibility of scaring. A total of usually 1 to 3 session is required to completely remove a mole. Do it slowly rather than a rash manner to excise it completely. The deeper you go, usually deeper than the reticular dermis, the risk of scaring increases substantially.
As the name suggest, we use a freezing solution to freeze the face mole first, then shave it off by a scalpel. The stump is then cauterized. A caution is that if suspected of a melanoma, there should be no freezing done as this causes a freezing artefact of the tissue sample and interfere with the histopathological interpretation. Instead a full surgical excisional biopsy should be done. The resulting elliptical skin deficit is sutured and approximated back.
This is usually performed if the lesion leaves in doubt the possibility of melanocytic nevus being a melanoma. Then a full and complete excisional surgery be done so that no melanocyte cell is left there for it have the recurrent nevi. An eye shaped or elliptical designed excision which should at least has 0.3 to 0.5 cm of clearance for the mole margin. The excised sample must be sent for histopathology examination to confirm that the mole has been fully excised with a clear margin of safety.
This will depend which method is used and where is the mole located as well as the size of the mole.
