Is is possible to change my face shape? (Photo)

I need to see other views of your face. It looks like you could benefit from cheek implants which will make your cheeks more prominent and lower face look more narrow. I would not do bucfat removal. As you age you will need this fat.

Buccal fat pad removal and botox to the masseters will slim your jaw and give you a more chiseled lower face.  It is truly amazing what can be accomplished with these two modalities.  The buccal fat pad removal is done in office in about 30 minutes under local anesthesia.  The botox to the masseters takes 10 minutes.  Minimal downtime.

Buccal fat removal is a very small operation that could be a good start for you. This surgery removes about a gumball-sized chunk of fat from the inside of each cheek hollow. The results are usually modest, but permanent, and should not be done in a person with a thin face. Botox injections to the masseter muscles can thin the jawline if you feel your jaw is too wide. Results last about 6 months.good luck!

May want to look into buccal fat removal to start and see how you like the change.AYou also need to be more specific about the exact changes you want

You have some very good options.  For patients who state that their face always appeared round despite loss of weight removal of the buccal fat pads can be subtle but very effective.  A side benefit in my experience is that it tends to highlight the cheekbone area despite the fact that they weren't touched.  After you've healed you'd have the option of small amounts of filler added to your cheek prominences if you would like.  That's usually very successful if not overdone.Finally, depending upon how thick and what bulk your masseter muscle has (tested by clenchin your teeth and feeling them), botulinum injection (Botox or Xeomin) can temporarily reduce the width of the back portion of your jaw.  My guess is that you'd be very pleased by the changes.
