Is there any risk or failure after punch excision of chicken pox scars?

For chickenpox scars, I recommend a combination of lasers, subcision and fillers. I recommend getting a formal evaluation with a cosmetic dermatologist. Best, Dr. Emer

With any excisional procedure, there is always a risk of a scar formation that is more noticeable than the original scar. This is however not expected. Subcision and filler can be used as well. Subcision and filler is generally better for rolling or stretchable scars. Punch excision is better for deep ice-pick or pinpoint scars. Hope this helps!Johnson C. Lee, MD

Yes, this is the most common complication of punch excision in this context. The decision of surgical vs surgical subcision and fillers should be based upon the size of the scar, the area, surgical technique and most importantly, - post operative wound care. The last factor is the most important in reducing the incidence of wound spread (apart from correct suturing technique). All the best, Dr Davin S. Lim. Brisbane, Australia
