Second intention healing after Mohs micrographic surgery

BACKGROUND: Although second intention healing has been used for many years in Mohs micrographic surgery, it has lost popularity. This is due to the long process and functional alteration of important anatomical units if certain wound healing factors are not carefully taken into consideration. OBJECTIVE: To review indications, contraindications, complications, advantages, disadvantages, as well as basic concepts of the wound healing process, wound care and antibiotic prophylaxis in the management of open wounds after Mohs surgery. METHODS: A short but comprehensive review of studies published in the literature dealing with second intention healing as a reconstruction alternative option in certain situations. CONCLUSIONS: Second intention healing is a simple and cost-effective method for reconstruction after Mohs micrographic surgery in well-defined cases. It allows adequate tumoral control with good to excellent functional and cosmetic results.
