Correction of depressed scars following Mohs' surgery: the role of collagen implantation

The results of injections of Zyderm™ collagen implant in six patients for correction of depressed scars on the nose resulting from Mohs' surgery are presented. Two cases are illustrated. Three of the six patients achieved 85–100% correction after completion of their series of injections. The one patient who achieved 100% correction subsequently experienced 15–20% regression, although none of the other five patients showed regression of the correction achieved.
