Otoplasty On My 7 Year Old 3 Weeks Ago, Noticed a Hole Behind the Ears?

The good news is that the skin behind her ear which has come apart does not hold the ear down to the side of the head.  There is a whole bunch of internal sutures and maneuvers that hold the ear in the new position.  It is hard to say without an in person physical exam, but my educated assumption would be that your daughter had a collection of blood known as a hematoma.  This created pressure behind the ear, and as the sutures dissolved, the hematoma leaked out onto her headband. 

I doubt that she is actively bleeding at 3 weeks, therefore, if no infection intervenes, this wound should heal quickly and without complications.  If anything changes, redness, foul smell, etc., please see your plastic surgeon asap.

Otoplasty incisions typically heal quite rapidly,usually within the first week.  However, it sounds like there was wound separation in the incision 3 weeks after the procedure which is unusual.  If the separation was relatively minor, tape or a steristrip may be a good option.  If the separation is larger, a suture may be a better option.  Speak with the intermin physician (presumably trained in otoplasty surgery and/or incisions) or consider advice from a nearby surgeon if your original surgeon is not available.

It's unusual for a wound to open, with a head band on, 3 weeks following otoplasty surgery. If the appearance of your child's ears looks favorable, further surgery might not be necessary.

Your surgeon likely has a "covering" physician while he's out-of-town. If not, get a second opinion from another reputable facial plastic surgeon for reassurance, and to rule-out infection and to answer the question whether any short-term intervention may be necessary.

Hope this helps you.
