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

The results of injections o 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.
