Actual (reported)This study is for patients with oropharyngeal squamous cell carcinoma. We want to learn more about how we can optimize pain control in patients who undergo transoral robotic surgery (TORS) for oropharyngeal squamous cell carcinoma. Our goal is to determine if a local anesthetic called EXPAREL® (Liposomal Bupivacaine) impacts postsurgical pain and swallow function in patients with oropharyngeal squamous cell carcinoma undergoing TORS. EXPAREL® is an FDA-approved anesthetic drug that provides long-lasting and precise pain relief when injected into the surgical wound. Our study team wants to determine if injecting EXPAREL® into the surgical wound will provide better pain relief and swallow function when compared to patients who do not undergo postoperative EXPAREL® injection. Both options for postoperative pain control are considered standard of care for patients undergoing TORS.

Actual (reported)Postoperative Pain Control
We will be measuring subjects' postoperative maximum visual analog pain scores on each postoperative day. Scale: 0-10, 0 represents no pain and 10 represents the worst pain
3 months
Postoperative Dysphagia with Endoscopic Swallow Study
Patients will undergo a functional endoscopic swallow study with a speech language pathologist during their first postoperative visit.
3 months
Postoperative Dysphagia with Dysphagia Survey
Patients will undergo an evaluation of their swallow function via the MD Anderson Dysphagia Inventory survey with a speech language pathologist during their first postoperative visit.

Per standard of care, at the conclusion of the TORS procedure, liposomal bupivacaine will be injected into the surgical bed- (bupivacaine liposome suspension 1.3% \[13.3 mg/mL\], intramuscular) in this group. Possible injection sites include the base of tongue and/or tonsil. Total dose injected will be 3-4 mL. Subjects will also be given a pain regimen including: 1. Tylenol 650 mg every 4 hours as needed for mild pain 2. Oxycodone 5 mg every 4 hours as needed for moderate pain 3. Morphine 2mg every 3 hours as needed for breakthrough pain The treatment type (TORS +/- Liposomal Bupivacaine + Postoperative Antipyretics and Opioids) is determined by the subject's surgeon based on his standard practice.
