The purpose of this study is to evaluate and reduce pain and improve quality of life in patients being treated for head and neck cancer with primary tumor resection and bilateral neck dissections. Patients will be randomly assigned to receive either pre-operative pregabalin (Lyrica) or a placebo. Patients and investigators will be blinded to which medication patients receive, and all patients will receive the same postoperative pain medication regimen with appropriate pain treatment as needed. Patients will be asked to fill out surveys prior to surgery, while in the hospital after surgery, and at each follow-up appointment for up to 24 months.

In this study, we will utilize single-dose pre-operative administration of Lyrica (pregabalin) compared to patients who will be administered a pre-operative single-dose placebo. Pregabalin is a non-narcotic GABA analogue that has been shown to be effective for the treatment of pain associated with a variety of medical conditions. Prior studies have investigated the use of single-dose pre-operative pregabalin for analgesia in acute dental, gynecologic, endoscopic thyroidectomy, and nasal septoplasty surgical pain with encouraging results demonstrating improved overall pain scores and decreased post-operative use of narcotics. Pregabalin's use for peri-operative analgesia in head and neck cancer surgery has not been evaluated. Patients who enroll in the study will be randomly assigned by chance to receive either a single pre-operative 150 milligram dose of pregabalin (Lyrica) or placebo in the pre-operative holding area prior to proceeding with surgery. Lyrica is a non-narcotic pain medication that has been shown to promote good control of nerve-related pain in patients. Patients who agree to enroll in the study will be asked to fill out separate questionnaires to evaluate pain and quality of life preoperatively and post-operatively. Participants will be asked to fill out four separate questionnaires to evaluate pain and quality of life pre-operatively. Patients will be administered their respective medication, either placebo or single-dose 150 milligram concealed capsule of pregabalin, by mouth in the pre-operative holding area prior to surgery. While in the hospital after surgery, patients will be given a regimen of scheduled acetaminophen 650 milligrams every 6 hours. Planned treatment of pain will include the option of requesting oxycodone on an as-needed basis every four hours and IV morphine for breakthrough pain. Surveys will be administered and collected on a daily basis while patients are in the hospital. If patients are already utilizing other non-opioid pain medications like muscle relaxers (Flexeril, baclofen, etc.), or neuropathic pain medications (Neurontin), they will be allowed to continue these medications while inpatient provided there are no changes in dosing. Patients will be discharged home on a seven-day course of acetaminophen with as-needed oxycodone. Outcomes surveys will then be collected at each subsequent post-operative follow up. Follow up visits will occur one week after discharge, four weeks after discharge, and then every three months until completion of the two year study period.
