Can a partial digastric myectomy improve my neck contour? Need gland, muscle shaping expert advice. SMG's aren't issue.

It is too early to make conclusions. You are in the worst period (some swelling, thick scars, adhesion) in the entire treated area. Let everything settle (at least 6-8 months) and then re-evaluate and treat very conservatively (digastric muscle shaving, thin fat grating of anterior neck, etc.). Patience is most difficult to ask for but you can not do much at the time being. Good luck.

Thank you for the pics and question. Based on the pics, it’s clear that removing fat has its consequences, such as more visible muscles underneath the skin. Removing more muscle would further reduce the volume thus making the “indent” worse. My recommendation would be to do nothing for now, except gentle scar massage, and return in 6 months for re-evaluation. At that point the tissues will have healed and softened more and decisions can be made as to the next steps. Some folks need more skin tightening, others may need fat replacement. Either way, right now is too soon to make that decision. Discuss this with your PS. Good luck. 

I think you are too soon post op to consider surgery for the time being. The last time you posted I suggested botox which will atrophy the glands as well as the digastric muscle temporarily.  As people routinely remove the muscle the botox shouldn’t effect your swallowing
