Otolaryngology patient satisfaction with these visits has not yet been extensively studied using a validated survey. Methods All patients who had telemedicine visits with three head and neck surgeons, by phone or video-based platform, between March 25, 2020 and April 24, 2020. Retrospective chart reviews were conducted to determine demographic, disease, and treatment information. Patients who had a video visit were contacted by telephone and, if they could be reached and consented, were administered the telehealth usability questionnaire (TUQ). Results Hundred surveys were completed. The average score across all questions was 6.01 on a scale from 1 to 7, where 7 indicated the highest level of patient agreement. The highest scores were for questions related to satisfaction with telehealth (6.29), while the lowest were related to reliability (4.86). Conclusions Patients are generally highly satisfied with telemedicine.Background Associations between brain total sodium concentration, disability, and disease progression have recently been reported in multiple sclerosis. However, such measures in spinal cord have not been reported. Purpose To measure total sodium concentration (TSC) alterations in the cervical spinal cord of people with relapsing-remitting multiple sclerosis (RRMS) and a control cohort using sodium MR spectroscopy (MRS). Study type Retrospective cohort. Subjects Nineteen people with RRMS and 21 healthy controls. Field strength/sequence 3 T sodium MRS, diffusion tensor imaging, and 3D gradient echo. Assessment Quantification of total sodium concentration in the cervical cord using a reference phantom. Measures of spinal cord cross-sectional area, fractional anisotropy, mean diffusivity, radial diffusivity, and axial diffusivity from 1 H MRI. Clinical assessments of 9-Hole Peg Test, 25-F
