Robotic-assisted gynecologic surgery associated tympanic membrane perforation: A report of two cases and review of the literature.

Robotic gynecologic surgery is associated with the use of steep Trendelenburg positioning. Steep Trendelenburg is necessary to provide optimal exposure to the pelvis but is associated with an increased risk of non-surgical complications such as suboptimal ventilation, facial and laryngeal edema, increased intraocular and intracranial pressure as well as neurologic injury. Several case reports have described otorrhagia after robotic assisted surgery; however, there are limited reports on the risk of tympanic membrane perforation. To our knowledge, there are no published reports on tympanic membrane perforation in gynecologic nor gynecologic oncology surgery. We report two cases of perioperative tympanic membrane rupture and bloody otorrhagia associated with robot-assisted gynecologic surgery. In both cases otolaryngology/Ear Nose and Throat (ENT) was consulted, and the perforations resolved with conservative management.
