Curettage leaves an excellent cosmetic result; does not require the surgical site to be rested, has few complications and is economical. If the resulting wound is less than half a millimetre deep, this will often leave an almost invisible mend. However, the deeper the wound, the more likely that the eventual scar will be white.
Deeper and wider curettage can take several weeks to heal, especially if the wound is on the trunk or limbs.
A curved surgical blade is used to remove the unwanted bit of skin. The wound if then sealed with an airtight dressing until it heals.
Curettage works well especially well on the face, trunk, arms and thighs providing that the wound is shallow and less than a centimetre in diameter. On the lower legs, the wounds tend to take several weeks to heal.
Larger or deeper wounds take an inconveniently long time to heal and often leave a poor cosmetic result. Drawing the wound edges together with stitches is a better option.
If the skin lesion is flat or growing under the surface of the skin, surgery involving stitches is needed.
Curettage is usually carried out under local anaesthetic and so is extremely safe.
The injection of local anaesthetic is uncomfortable, especially on the face. After that the procedure is painless. The best surgeons, like the best dentists, will inject the local anaesthetic very slowly, give it time to work and test it out carefully before they start operating.
No special preparation is needed.
The skin lesion is removed with a sharp blade leaving a small graze. Often it is necessary to cauterise the graze to stop it bleeding, particulary if you are taking aspirin.
The wound will be covered with a plaster and sometimes there may be a little bruising from the injection.
The local anaesthetic lasts 2-4 hours. Once it wears off, the wound is not normally painful. However, if the wound hurts, take paracetamol-based painkillers and avoid those containing aspirin or ibuprofen. After that, you will need to follow the wound care instructions that will vary with the type of dressing that is used.
Approximate healing times are: seven to ten days for small, shallow wounds, two to three weeks for larger shallow wounds and four to twelve weeks for deeper wounds and those below the knee.
The healed wound will be pink for between two months if on the face and for up to two years if on the lower leg. If exposed to strong sunlight during the first few months, the wound may become browner than the surrounding skin. This colour mismatch can take several months to disappear. Some wounds, particularly deeper ones, heal to leave a permanent white mark. Thick scars can occur, mainly in people under 25 years of age.
It is probably best to avoid injections of local anaesthetic during the first twelve weeks of pregnancy when possible.
