Uneven ears? One ear higher than the other (from behind).

HI!.I had an otoplasty on my left ear three months ago because it used to stick out more than my right one.However now i notice that my left ear is also higher than my right one.Could this be due bad otoplasty,some kind of trauma(i got hit by a bottle of water 2 weeks post op but i didn't notice anything conserning.My doctor also confirmed that no damage had occurred)or was it like that the whole time and i never noticed?What kind of surgery can i have to aligne it with my right ear.Thanks.
