Enhanced recovery after orthognathic surgery: a retrospective comparison study of 56 patients.

Enhanced Recovery After Surgery (ERAS) protocols have been demonstrated to expedite recovery and decrease hospital stay from multiple surgical specialties. This study sought to determine how an ERAS protocol would improve patient outcomes with regards to inpatient postoperative nausea, vomiting, and pain scores following orthognathic surgeries. This was a retrospective study comparing patients who underwent orthognathic surgery with and without an ERAS protocol. The primary measurables included opioid consumption, antiemetic medical consumption, nausea and vomiting incidences, and pain scores between the two groups during their hospital stays. A total of 56 patients were retrospectively analysed comparing ERAS protocol to non-ERAS protocol. The maximum pain score of the ERAS group was 5.50 out of 10 compared to the control group of 7.50 out of 10 (p<0.001). Morphine equivalent consumption during their time in the ward was statistically significant (51.4 mg control versus 9.4 mg ERAS group). ERAS protocol is safe and effective for decreasing postoperative pain and nausea. The ERAS protocol is not only applicable for orthognathic surgery but should be highly considered for other maxillofacial surgeries.
