Post-Op Otoplasty, Should I Use Vaseline on the Wound to Avoid Scarring?

Generally I recommend using antibiotic ointment for a couple of weeks as this helps the healing process. I think vaseline would be ok but you should check with your PS. 

Thank you for the question.

Specific aftercare instructions should be provided by your plastic surgeon. Personally, I do not ask patients to use any solution/lotion on the suture line.  The  suture lines tend to heal very nicely;  sometimes manipulation can do more harm than good.

Again, please check with your plastic surgeon for specific  instructions.

Best wishes.

Normally scarring is minimal with otoplasty because the incisions are located behind the ear.  As it sounds like you had extra work along the earlobe, then a combination of diluted Hydrogen Peroxide to cleanse the crusts and Bacitracin ointment to keep the incision line moist is our usual regimen.  In the long term after initial healing, Vitamin E massage can help to soften any scarring.  Be sure to call your surgeon to find out what their protocol is for post operative situation.
