Our Mission:

To educate about voice, swallowing, airway, coughing, and other head and neck disorders in order to help people work more effectively with their personal physicians.
What learning materials do we have?
  1. Multimedia encyclopedia entries, including photos, videos and audio files, all about disorders of the larynx, throat, and upper airways.
  2. A stand-alone video gallery.

How to browse our learning materials:

  • By topic: choose a topic from our menus (e.g., hover over or tap on "Disorders" on the menu bar and select "Swallowing disorders" from the drop-down menu).
  • By keyword: use the search box to look up entries.
  • Alphabetically: search all entries organized by letter.

Our most popular content:

  • R-CPD (The inability to burp): Retrograde Cricopharyngeus Dysfunction is a condition where the upper esophageal sphincter (cricopharyngeus muscle) cannot relax in order to release the “bubble” of air.
  • Still Coughing After COVID-19? Some patients who have recovered from COVID-19 still experience a lingering cough. One cause could be Sensory Neuropathic Cough, where the infection has “damaged,” or “sensitized” sensory nerve endings in the trachea, larynx, or throat.
  • Cricopharyngeal Spasm: Hyper-contraction of the cricopharyngeus muscle, which causes a constricted or lump-in-the-throat sensation. Cricopharyngeal spasm is a harmless disorder, but it can cause great anxiety for somebody who is experiencing it and has not received a clear diagnosis for the symptoms.
