A clinical case of a patient with an anomaly in the development of the inner ear and refractory stimulation of the facial nerve after a coronavirus infection and meningitis

Background. Thanks to the development of technology and new surgical approaches, it has become possible perform cochlear implantation (CI) in patients with malformations inner ear. The experience this type rehabilitation more than 15 years Russian practice 20 world. Unfortunately, COVID-19 pandemic added not only one cause deafness, but also etiological factor complications. purpose paper is describe a clinical case facial nerve stimulation (FNS) CI user an ear malformation coronavirus infection complicated by meningitis. A demonstrating combination all these factors FNS been previously described scientific literature.
 Aim. To meningitis.
 Materials methods. In 2017 4 old patient underwent on her right Saint Petersburg Research Institute Ear, Throat, Nose Speech. May 2022 was admitted infectious diseases department medical institution diagnosis: (confirmed), severe course; complication: purulent meningoencephalitis. After recovery, complained muscles twitching when using speech processor implant. order correct non-hearing sensation, sent Speech for June 2022. During repeated fitting, improve reactions sounds. Phoneme discrimination improved. Positive dynamics registered against background changed settings. average hearing thresholds 3-phase were 42.5 dB. However, completely eliminate FNS, compulsory settings did allow achieve sufficient intelligibility.
 Conclusion. Meningitis after can increase transmittance tissues electric current and, as consequence, FNS. Modern technologies make rehabilitate such patients, including those abnormalities effecacy rehabilitation, special coding strategies are used stimulation.
