Thank you for your question and for including a profile photo to help me understand your concerns better. From the photo you sent, it appears that your lower jaw and chin is relatively more pronounced and in a more forward position. The angle between your upper lip and your nose is slightly less than 90 degrees and may possibly indicate that your upper teeth do slant forwards to compensate for the more forward position of the lower jaw. Your lip position is quite acceptable and they do close quite nicely, though the lower lip is more forward than the upper lip.
Corrective jaw surgery in your case will aim to harmonise the upper and lower jaw relationship with the lower jaw position being set backwards. You will notice the chin position will be pushed backwards and the lower lip will follow along too.Your surgeon may also want to move your upper jaw forwards slightly to increase the fullness of the cheek area or more accurately the paranasal region as they do look mildly flattened. In order to assess if the upper jaw needs a forward movement without adversely affecting the nose to upper lip relationship, a lateral cephalogram radiograph will be necessary to assess the inclination of the teeth and the position of the upper and lower jaw with respect to the rest of the face.
Corrective jaw surgery remains a personal choice and this has to be discussed together with your doctor to determine if the facial changes anticipated addresses your concerns.
Hope this helps and all the very best,
