Local Anesthetic Effects During Submentoplasty
During a submentoplasty, local anesthetics block pain signals from local nerves and constrict nearby blood vessels to minimize bleeding and swelling. Only small amounts eneter the bloodstream, rarely causing systemic issues when kept under safe dosage limits.
Clinical Context
Safety with local anesthetic during submentoplasty depends mainly on the total dose given relative to body weight. Because the area under the chin has a rich blood supply, the anesthetic can absorb into the bloodstream faster than in less vascular areas. Surgeons often add epinephrine, which narrows blood vessels, slows that absorption, and extends numbness. Surgical teams calculate safe dosing limits beforehand and keep track of how much has been used if more anesthetic is needed during a longer procedure.
