To examine the feasibility of outpatient alveolar bone grafting (ABG) using Exparel (bupivacaine liposome injectable suspension) for donor site analgesia. Retrospective, observational study. Single institution, 39-month retrospective review. In total, 21 patients with cleft alveolus were included in this study. In autologous outpatient ABG procedures using a mixed open harvest and Acumed trephine method to retrieve corticocancellous bone from the iliac crest, Exparel was injected in the donor site fascia. Postoperative data including length of stay, post anesthesia care unit narcotics delivered, and maximum pain scores were recorded. Successful outcomes were assessed by exploring 30-day complications, 30-day emergency department visits, 30-day readmissions, and ambulation at follow-up. The average hospital length of stay was 360.8 min. Four patients required overnight stay secondary to pain. The average doses of pain medications administered postoperatively were 198.4 mg acetaminophen, 9.3 mg ketorolac, 3.0 µg fentanyl, and 1.5 mg oxycodone. No patient reported 30-day complications secondary to donor site pain, 30-day emergency department visits, or 30-day readmissions, and there was only one case of wound dehiscence. All patients exhibited proper ambulation at follow-up and healed well from ABG. The use of Exparel for donor site analgesia in outpatient ABG procedures using corticocancellous grafts can result in adequate pain management and ambulation without an increased risk of complications and readmissions.
