Crease on Upper Lip After Rhinoplasty?

The post operative "creasing" of the upper lip in the horizontal plane occurs because of swelling in most cases. But if your rhinoplasty surgeon released the muscle connections from the septum and anterior nasal spine than the vertical muscle fibers contract in that vertical plane causing the horizontal creasing. Or it could be a combination of both reasons. It appears as if you had an open rhinoplasty thus this approach also has a higher occurrence of this creasing effect. In most cases there is improvement over a 3 month healing time but in some cases a filler or even very very low dosed BOTOX is needed. Best to consult with your surgeon. 

The crease is from muscle animation. It could be from swelling or release of muscle to prevent the tip from plunging.  Check with your doctor.
