Long-acting anesthetic injection to reduce pain after throat cancer surgery

This trial is testing whether liposomal bupivacaine—a long-acting numbing medication—can help reduce pain and improve swallowing after robotic throat cancer surgery. Some patients will receive an injection of this medication directly into the surgical site at the end of their operation, while others will receive standard pain management alone. Both approaches are considered normal care, so the study is comparing which works better.

After throat cancer surgery, patients often struggle with significant pain and difficulty swallowing, which can affect their recovery. This trial wants to see if the medication can provide better pain relief and help patients swallow more easily, potentially reducing the need for opioid painkillers.
