Infection after otoplasty
Redness after otoplasty is common, and its difficult to tell from the photos whether you have an infection or not. Ears are prone to blood collections and infection post surgery and an examination will help elucidate whether an infection is present in your case. Significant pain is definitely an indication for you to be reviewed by your treating physician.
I believe it is the moral obligation of the operating surgeon to see his/her patients post operatively, and be available should there be any potential risks and complications.
The pictures posted and the fact there is reddness, increased pain few days after surgery points to the possibility of infection. It should be examined by the operating physician and decision should be made as to the best treatmet option.
