Comparison of general anesthesia and monitored anesthesia care for sialendoscopy procedures.

The literature remains scarce in terms of comparing different anesthesia modalities in sialendoscopy. Due to the lack of a standard of care or guidelines to anesthetic care, it is generally accepted that surgeons perform these surgeries under the anesthetic modality in which they are most comfortable. In this study, we evaluate time spent on the day of surgery and post-surgical outcomes for patients receiving sialendoscopy under monitored anesthesia care versus general anesthesia. We retrospectively assessed patients who underwent sialendoscopy using a solely endoscopic approach for sialadenitis or sialolithiasis from March 2017 to December 2019. Anesthesia modality (monitored anesthesia care versus general anesthesia) was compared. Main outcomes included total time in hospital, operative time, total time in operating room, anesthesia time, and recovery time. Secondary outcomes included rate of resolution of symptoms, requiring further medical management, requiring further surgical intervention, and complications. A total of 172 procedures were included. Sialendoscopy under monitored anesthesia care center compared to general anesthesia decreased median hospital time (141 min reduction), anesthesia time (46 min reduction), operative time (24 min reduction), time in operating room (43 min reduction), and recovery time (56 min reduction). Utilizing monitored anesthesia care demonstrated similar rates of post-operative resolution of symptoms, complications, and further medical or surgical intervention compared to the general anesthesia cohort. Sialendoscopy can be safely performed under monitored anesthesia care for appropriate sialadenitis or sialolithiasis cases while decreasing hospital time, operative time, time in operating room, anesthesia time, and recovery time while maintaining similar post-operative outcomes. Monitored anesthesia care should be considered for solely endoscopic cases as guided by surgeon and patient comfort.
