Description
Keisuke Nakazawa and colleagues tested whether a guided jaw muscle block eases pain after impacted wisdom tooth removal. Their 2026 study looked back at forty-eight patients treated at two centers under general anesthesia. Twenty-seven patients also got an ultrasound-guided block into the lateral pterygoid muscle, a deep jaw muscle, while twenty-one did not.
Six hours after surgery, the block group reported a median pain score of zero at rest, against three in the comparison group. Scores also ran lower at two hours and later that evening, then evened out by the next morning. Block patients waited a median of ten hours for their first rescue pain drug, against seven hours for the others, though that gap was not firm. No harm tied to the block was recorded. The authors call the results early hints, pointing to a registered trial now testing the idea.
