Abstract
The article presents our experience of cochlear implantation under regional anesthesia in adult patients. For the patients who lost hearing in older age, this surgery is an opportunity to improve speech perception and speech intelligibility, as well as to raise the life quality and socialization level. A prospective group for cochlear implantation under regional anesthesia is the group of elderly patients. If operated under general anesthesia they may experience the development of postoperative cognitive dysfunction, confusion of consciousness and postoperative delirium. At the period from January 2011 to December 2018, eleven patients underwent unilateral cochlear implantation under local anesthesia in Saint-Petersburg Research Institute of Ear, Throat, Nose and Speech. Three patients were above 60 years. All the patients tolerated the surgery well. The study of cognitive function was not conducted after surgery, but the patients did not make specific complaints indicating the development of cognitive dysfunction. Cochlear implantation under regional anesthesia is a safe procedure in patients with severe concomitant somatic pathology when general anesthesia is contraindicated. The operation under regional anesthesia increases the availability of cochlear implantation to more patients, eliminating the risks of general anesthesia.
