COVID-19 infection is associated with a variety of neurological manifestations. Since the inner ear is vulnerable to viruses, sensorineural hearing loss (SNHL) has been reported to occur following SARS-CoV-2 infection. We present here two cases of profound SNHL following SARS-CoV-2 infection. Pure-tone audiograms confirmed profound SNHL. The tympanogram and Auditory Brainstem Responses showed no abnormal symptoms. MRIs and CTs identified some changes but no significant anatomical nor physiological manifestations explaining the obvious cause for hearing loss. High doses of oral corticosteroids with additional conservative therapy were given with no therapeutic response, and therefore, cochlear implant surgery was performed. One case was bilaterally treated, and the other one received an implantation on one side. Both surgeries were carried out without intra- nor postoperative complications. Interestingly, in both cases, advanced fibrotic tissue was found during surgery. Both cases reported successful rehabilitation and are satisfied with their new sound perception following cochlear implantation. © 2023 by the authors.

Intraoperative hypertension (IOHTA) during neck surgery is undesirable because this type of surgery has a propensity to bleed profoundly even in normotensive anesthesia. The purpose of our study was to detect predictors of IOHTA in patients undergoing neck surgery. This single center retrospective study included 880 adult patients who underwent neck surgery under general anesthesia. The impact of gender, age, comorbidity, difficult tracheal intubation, anesthesia duration, and induced hypotension on IOHTA was studied. IOHTA was present in 57 (6.7%) patients. The highest incidence of IOHTA was recorded in patients with ASA 4 status and those with Cormack-Lehane grade 4,: (22.2% and 21.4%, respectively). Significantly more patients with hypertension, hyperlipoproteinemia and ventricular extrasystoles had IOHTA compared with patients without these comorbidities. Statistically significant predictors of IOHTA were age (OR 1.438; 95% CI 1.144-1.808; p=0.002), cardiac arrhythmia (OR 1.702; 95% CI 1.129-2.566; p=0.011), Cormack-Lehane grade (OR 1.407; 95% CI 1.054-1.878; p=0.020), and duration of anesthesia (OR 1.005; 95% CI 1.001-1.008; p=0.005). The risk of IOHTA occurrence was lower in patients with induced hypotension (OR 0.024; 95% CI 0.003-0.185; p=0.000). During neck surgery, special attention is needed in patients of older age, those with cardiac arrhythmia, difficult intubation, and longer anesthesia duration because they are at risk of IOHTA. © 2023, Dr. Mladen Stojanovic University Hospital.
