Dr. Ramanathan was born and raised in Dallas, TX, and received a bachelor's degree in Molecular Biophysics and Biochemistry from Yale University. He subsequently received his M.D. from The University of Texas Medical Branch at Galveston where he graduated with highest honors and completed his internship in general surgery and residency in otolaryngology-head and neck surgery at Johns Hopkins. During residency, Dr. Ramanathan focused on researching the pathogenesis of chronic rhinosinusitis which resulted in numerous presentations and publications at national meetings. Upon completion of his residency, he received additional fellowship training in advanced endoscopic sinus and minimally invasive skull base surgery at Johns Hopkins.
Dr. Ramanathan evaluates patients primarily at the Johns Hopkins Healthcare and Surgery Center in Bethesda, Maryland, as a part of the greater Washington D.C. region practice of Johns Hopkins Otolaryngology-Head and Neck Surgery. If indicated, he can also perform surgery at Suburban Hospital in Bethesda.
His clinical interests include chronic rhinosinusitis with nasal polyps/chronic frontal sinusitis, surgery for nasolacrimal duct obstruction/thyroid eye disease, and endoscopic approaches for resection of sinonasal and anterior skull base tumors. As an active clinician-scientist, Dr. Ramanathan also has a mentored career development award funded by the National Institutes of Health to study the role of environmental pollutants in propagating chronic sinusitis and allergic rhinitis with collaborators at Johns Hopkins School of Medicine and the Johns Hopkins Bloomberg School of Public Health.
