Buccal fat removal: Opened up stitch on one cheek! Will I still heal properly? Very swollen compared to other side! (photo)

Buccal fat removal stitches could potentially dissolve before time and therefore allow the wound to remain open. In these cases would would ultimately heal but slower than if it was stitch-closed. In my practice I recommend my patents to rinse their mouth with medical grade mouth wash and take oral antibiotics for several days after surgery to prevent any infection  even if the oral incisions open up. 

I recommend following up with your surgeon. Keep in mind, swelling is typical and can be asymmetrical. It will gradually resolve over the next several weeks. Hope this helps.
