Rahul Seth, MD

Associate Professor

Dr. Seth is the primary inventor of a device which helps determine the presence of abnormal fluid in a middle ear of a patient, a challenging aspect of an ear exam for many practitioners. The device includes two light sources, including a laser light beam. The conveyed optical beam creates a reflectance pattern and the illumination characteristic provides insight into the presence of any abnormal fluid in a middle ear of a patient. A substantially diffuse reflectance pattern observed indicates the presence of abnormal fluid in the middle ear of the subject. With new technologies and procedures, there are numerous options for each patient that range from office procedures to operative techniques. Dr. Seth’s goal is to work with patients to choose the best options, whether patients desire enhancement in appearance, reconstruction after a trauma, or cancer-related surgery. He is committed to provide the highest standard of care so that his patients achieve their individualized aesthetic goals.
