John Mayer, on September 16, 2011, blogged that he has been diagnosed with a vocal fold granuloma which has caused him to cancel his signing engagements and postopone the release of his next album.
A vocal process granuloma is inflammatory tissue located adjacent to the vocal folds. Located on the back portion of the vocal folds, granulomas prevent full closure of the vocal folds. When large, granulomas cause symptoms including hoarseness and difficulty speaking or singing. Granulomas occur due to numerous causes, including voice overuse, acid reflux from the stomach, recent cough, or even after surgery in which a breathing tube is placed between the vocal folds.
Granulomas are diagnosed during laryngoscopy, in which an otolaryngologist uses a small camera through the nose or mouth to view the vocal cords and larynx.
While granulomas, are not cancer, they are very difficult to cure. Those with granulomas are often placed on voice rest and are asked to use their voices only when absolutely necessary. If acid reflux from the stomach is determined to be a contributor, acid reflux medication and dietary changes are employed.
Injections to the granuloma with steroid may be helpful in decreasing the swelling and reduce the size of the granuloma. In fact, inhaled steroids, similar to those used for asthma may help as well. Lasers, including KTP and PDL, in the office may be used to decrease the size of the granuloma.
Surgery for granulomas unfortunately is usually not sucessful. Although a granuloma may easily be removed, it often returns weeks to months later.
