We retrospectively compared incidence of recurrence of malignancy in patients with advanced head-and-neck malignancies who had undergone excision with reconstruction surgery 1 year back and had received two different regimens of opioid free anesthesia (OFA) versus standard regimen using morphine. Durations of surgery, intensive care unit (ICU), and hospital stay and mortality at 1 year were also compared.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Retrospective analysis conducted in 150 patents comprising of three equal groups. Group L had received intravenous lidocaine bolus 1.5 mg\/kg followed by infusion 1 mg\/kg\/h. Group D received intravenous dexmedetomidine 1 mcg\/kg bolus with ketamine 0.5 mg\/kg followed by dexmedetomidine 0.5 mcg\/kg\/h with ketamine 0.5 mg\/kg\/h infusion. Group M received morphine 0.2 mg\/kg bolus followed by an infusion 2 mg\/h. The disease process at 1 year following surgery was assessed by reviewing medical records and contacting the patient or relative telephonically.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Mean durations of surgery and ICU stays were comparable in all three groups. Duration of hospital stay was significantly lower in Group L. Patients in all groups had comparable regular postoperative follow-up visits. Incidence of recurrence of malignancy within 1 year of surgery was significantly lower in Group L. Mortality was comparable in all three groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n
