Post-OP instructions - Arthrocentesis
Freely use your jaw. There are no food restrictions. Chew liberally. Chew gum in large piece (bubble gum).
Apply ice/cold compress, 15 minutes on, then off, every 2-3 hours for first 24 hours. Then, apply most heat, again for 15 minutes on, then off, every 2-3 hours.
You may notice blood in the area surrounding the ear in the first 24 hours. Use an old pillow case to avoid staining new sheets.
The effect of the local anesthesia will disappear 2-4 hours after the procedure.
