Neck pain while yawning at surgery area of acdf4-5-6 at scar from plate removal?

Discuss with MD: I would definitely contact my surgeon to determine if any loss of stabilization occurred but in all likelihood it is not a major concern unless associated with other neurological deficits.

Traction neuritis : I f your surgery was relatively recent (within 6 months) it should be considered a normal part of post op healing. When you yawn there is enormous stretch and strong contractions of various neck muscles that don't get this range of motion except when yawning. If you try yawning more frequently the scar tissue at the surgery site will loosen over time leading to less pull on the nerves causing pain.
