Hi and thank you for your excellent question. There is a condition known as craniofacial micosomia (also known as hemifacial microsomia) where the tissues of one (rarely both) sides of the face are less well formed compared to the other side. It can affect all the layers and occasionally be associated with differences in other parts of the body. The condition is relatively rare but it is not that uncommon to have very mild versions of the condition where the profile only is mildly affected, and it looks that you may have this. Do you have any differences or concerns in relation to your jaws, teeth or bite? In terms of treatment options for you I have two main lines of thought - a safe volumising filler which of course would need to be repeated but modern fillers can now last 18 months or more and the treatment would be a simple outpatient office procedure. The other method would be fat grafting which is relatively straightforward and when performed well, can be considered to be permanent but you may require more than one episode of grafting to achieve optimal symmetry. Personally I would avoid implants for a problem with modest severity like in yourself but of course it would be sensible to have this checked out by a fully qualified plastic surgeon. Sometimes a filler can be used as a 'trial' prior to a more formal permanent correction so that you can get a taste of what the appearance will be like before committing to more permanent methods. I hope you found this information helpful and best wishes for the future.
