Superficial Cervical Plexus Block for Pain Relief in Maxillofacial Surgery

This study is focused on evaluating a pain relief method called the superficial cervical plexus block (SCPB) for people undergoing maxillofacial surgeries, which involve operations on the jaw and face. The researchers are comparing this method to the more common approach of general anesthesia. SCPB is a technique where a local anesthetic is injected near certain neck nerves to help reduce pain. The study is particularly important because it may offer a way to reduce the need for systemic painkillers that affect the whole body after surgery, potentially leading to fewer side effects and complications. Participants in the study will receive either the SCPB or general anesthesia before their surgery. The SCPB involves an injection guided by ultrasound to ensure accurate placement of the anesthetic. Researchers will measure several outcomes, including how long pain relief lasts, how much extra pain medication is needed after the surgery, pain levels using a visual analog scale, and any changes in vital signs. They'll also monitor for any complications that might arise from the procedure. Some potential risks of SCPB include injection into a blood vessel, hematoma (a collection of blood outside of blood vessels), infection, or local anesthetic toxicity, although these risks are generally lower than with deeper nerve blocks.
