First, the doctor will review the patient's medical history and symptoms, such as hoarseness, dysphonia, and reduced vocal range. There is no familial or hereditary link to Reinke's edema. Because Reinke's edema is linked heavily to smoking, the doctor will need to know if the patient is a habitual smoker. Once the patient's history is reviewed, the vocal cords will be visualized using laryngoscopy, a technique in which a tube with a camera (endoscope)
