what surgical options are available to address this concern?

I think your face proportion is good but lengths are little bit. The high hairline is one of the reasons and I can recommend hair transplantation for frontal area. Rhinoplasty and genioplasty (chin tip surgery) will also change the lenghts of middle and low thirds of the face. Finally with fat transfer to face I think we can achieve a nice and more balanced result in the face. Good luck.
