Patients presenting with persistent voice and swallowing disorders are initially evaluated with a careful history of the problem and ENT exam. A Flexible Fiberoptic Laryngoscopy is often used to examine the vocal cords. Afrin and local anesthesia is applied to the nasal passages, and the endoscope is inserted through the nose and into the throat. The patient can swallow and speak giving the doctor a more accurate view of the functioning vocal cords. After the examination, patients can immediately return to normal activities.
Digital Stroboscopy
Digital stroboscopy is sometimes used to analyze the motion of the vocal cord vibrations in order to identify any potential abnormalities that may be causing hoarseness, sore throat or other symptoms. The procedure is performed in the office and involves inserting an endoscope with a tiny camera on the end through the nose and into the throat. The stroboscope technology used will capture slow-motion images of the vocal cords while the patient speaks to provide clear, informative video of the rapidly moving structures, which can be viewed by the doctor and patient.
Transnasal Esophagoscopy
Transnasal esophagoscopy (TNE) is a minimally invasive diagnostic procedure used to evaluate the esophagus in patients suffering from a number of throat problems including laryngopharyngeal reflux, a condition that causes a chronic cough, throat clearing and a throat foreign body sensation. During the TNE, the nose is first numbed with a topical anesthetic before the endoscope is inserted in through the nose and down to the throat. Your doctor can examine the throat and vocal cords, including detecting any changes when swallowing. The endoscope will then be advanced into the esophagus and stomach, if necessary, for further examination.
The entire procedure takes just 5 minutes to perform. Patients will be able to drive themselves home after this exam and can return to work and other normal activities right away.
