When the Wound Heals Itself: Second-Intention Healing After Mohs

Not every Mohs defect gets stitches. Why surgeons sometimes let a wound close on its own, and what those weeks of care look like.

Patients are often surprised, and sometimes alarmed, when a Mohs surgeon recommends no stitches at all. The plan is called second-intention healing: the wound is left open, cared for daily, and allowed to close itself from the edges inward and the base upward. It sounds like neglect. It is actually a deliberate reconstructive choice with decades of results behind it, and in the right location it can heal as well as, or better than, a repair.

The right locations are mostly concave: the inner corner of the eye, the bowl of the ear, the temple, and certain curves of the nose. Concave surfaces let new tissue fill in level with the surroundings, and the scar that forms is often flat and pale. Convex surfaces like the tip of the nose or the point of the chin heal less predictably this way, which is why the same surgeon who suggests open healing on your ear may recommend a flap or graft somewhere else. For an independent overview, see Mohs surgery and reconstruction, society overview.

What the weeks actually involve

Expect four to eight weeks of simple, repetitive care: gentle cleansing, a layer of plain ointment, and a non-stick dressing, usually once a day. The wound looks worse before it looks better, passing through a red, moist granulation phase that healthy healing requires. Discomfort is typically modest and signs of infection are the same ones to watch for after any skin surgery: spreading redness, increasing pain, or cloudy drainage.

The trade is time for simplicity. There are no incision lines, no suture removal, and no flap that has to survive; there is instead a daily chore and a longer wait for the finished result. For smaller defects in the forgiving locations, long clinical experience finds cosmetic outcomes that patients rate highly, which is why this quiet option keeps its place beside more elaborate repairs.

If your surgeon offers it, ask the two questions that matter: is my defect in a location where open healing does well, and what will you do later if the scar needs a touch-up? Good answers to both usually mean the no-stitch plan is a considered one.
