Vocal fold nodules are bilateral whitish bumps located on the medial edge of the vocal folds at the midpoint. They are caused by vocal exuberance which means speaking in a loud voice, a high pitch, or speaking for long periods of time. When the vocal folds come together too hard, the delicate tissue can be damaged and callous-like bumps form where the vocal folds come together the hardest. If nodules are large enough, they can prevent the vocal folds from coming together and vibrating properly for phonation. Think of an hourglass shape with the vocal folds meeting in the center at the nodules, but not closing fully on either end. The voice may become hoarse, breathy, or aphonic and your pitch range may decrease, especially the high notes. What do they look like? What can I do? There are a number of options to help vocal nodules. Learning how to care for your voice and use it in a safe way is the first step. This may mean learning about vocal hygiene and using a clear, resonant voice to prevent further damage. Once you learn how to use your voice safely and keep your vocal folds healthy, nodules usually start to shrink. If, after a few weeks, vocal hygiene and resonant voice has not helped improve the voice, there are surgical options which can be discussed. 3 Contact Ulcers & Granulomas What are they? When the delicate tissue covering the cartilaginous glottis becomes inflamed, the area may ulcerate or produce heaped tissue which forms a granuloma. The damage may be from vocal misuse (e.g. speaking with a hard glottal attack, coughing, or throat clearing), intubation, laryngeal surgery, surgery after radiotherapy, or GERD (acid reflux inflames the tissue of the vocal process). Ulcers are usually accompanied by pinpoint pain. Granulomas, unless they are very large, may not cause problems. Both may give the sensation of something in the throat which may increase the harmful habit of coughing or throat clearing. What do they look like? What can I do? Learning about the detrimental voice habits which may have contributed to the formation of ulcers or granulomas is the first step is stopping them and allowing the larynx to heal. Proper vocal hygiene and using a resonant voice can also help prevent further damage and assist healing. Steriods may decrease healing time. Anti-acid regimens can help treat GERD and prevent further damage from acid. Surgery is not usually recommended for contact ulcers or granulomas because if the proper steps aren’t taken to prevent further damage, the change of recurrence is high and surgery results in vocal fold scarring. Usually, healthy vocal habits will begin to reverse the effects. 4 Polyps What are they? Vocal fold polyps usually develop on the medial edge of the vocal fold near the midpoint. They may be unilateral or bilateral, white or red, and vary in size and shape. They are usually caused by voice misuse or heavy voice use. Generally painless, polyps may result in incomplete closure of the vocal folds which can lead to hoarseness or breathiness. If a polyp is large, it may result in voice breaks due to interrupting the vibration of the vocal folds. It may also cause the sensation of something being in the throat which can lead to further damage from coughing and throat clearing. Reinke’s edema is a large, floppy polyp caused by the combination of smoking and excessive voice which results in weakened capillary walls, capillary leakage and swelling of the tissue. This can result in a hoarse or breathy sounding voice with a loss of high pitches. What do they look like? Polyp Reinke’s edema What can I do? Good vocal hygiene and use of resonant voice can help reduce the size of the polyp and minimize symptoms. Short periods of vocal rest, vocal naps, may help reduce vocal fold inflammation but long periods of vocal rest have not been shown to decrease the size of polyps. If voice therapy and healthy voice habits do not minimize the polyp enough to restore proper vocal quality, there are surgical options but these can result in vocal fold scarring and should be considered carefully. 5 Cysts What are they? Cysts are masses on the vocal folds caused by a build up of mucous from a blocked gland or a build up of keratin after vocal misuse. Cysts may be unilateral or bilateral and vary in size and shape. If the cyst is large enough, it may result in incomplete closure which can cause a hoarse or breathy voice. If the mass and stiffness of the vocal folds are increased due to a cyst, loss of high notes or breaks in phonation may be a consequence. What do they look like? What can I do? Cysts may clear up on their own if the built up fluid drains and voice therapy may reduce the size of cysts caused by vocal misuse and prevent further damage and future cysts. Usually, cysts which are very problematic are removed using surgical options but cysts must be removed completely to prevent recurrence and scarring is a concern. A ruptured cyst may result in a sulcus vocalis which will be discussed later. 6 Vocal Fold Hemorrhage, Sulcus Vocalis, &Vocal Fold Scarring What are they? Hemorrhage – A vocal fold hemorrhage is bleeding underneath the outermost layer of mucosa on the vocal folds. Usually caused by a single traumatic event (e.g. screaming “fire”), hemorrhages are the result of sudden vocal fold damage. Anticoagulants may increase the chance of vocal fold hemorrhage, especially when coupled with extreme voice use. Sulcus Vocalis – An indentation or furrow which runs along the length of a vocal fold is a sulcus vocalis. It may be the result of a ruptured cyst and may cause vocal fold bowing due to the decrease in tissue. Since people may need to exert more pressure to achieve closure, this may cause a pressed, harsh voice. Vocal Fold Scar – A scar on the vocal folds may be caused by trauma, surgery, burns, or inflammation. It increases the stiffness of the vocal fold which impacts vibration. What do they look like? Hemorrhage Sulcus Vocalis Vocal Fold Scarring What can I do? Hemorrhage – Immediate vocal rest following the incident is recommended. Sulcus Vocalis – Injections to bulk up the gap or push the vocal fold out to assist closure are the most common treatment options. Vocal therapy is usually not as effective. Vocal Fold Scar – The best treatment is preventing the scar in the first place. Once formed, vocal therapy may increase vocal function and reduce the impact of the scar. Surgical options should be carefully considered since they may make scarring worse or create additional scarring. 7 Papillomas & Carcinomas What are they? Papilloma – A papilloma is a benign tumor caused by the human papilloma virus (HPV). Papillomas may be unilateral or bilateral and affect the mucus membranes and the muscle of the vocal folds. They usually continue growing and vary in size and shape. Since they impact the closer and vibration of the vocal folds, they may result in a hoarse, breathy, or aphonic voice. Carcinoma – A carcinoma is a cancerous tumor which starts out unilateral and may spread around and beyond the larynx. It affects mass, stiffness, closure, and vibration of the vocal folds depending on size, shape, and location. Smoking and drinking increase the chances of developing a carcinoma. What do they look like? Papilloma Carcinoma What can I do? Papilloma – Surgery may be used to remove tumors temporarily but often, papillomas grow back. Since recurrence is common, voice quality is usually taken into consideration in the operating room. People with papillomas should speak with a doctor about treatment options. Carcinoma – As with other cancers, radiation, surgery, chemotherapy, or a combination may be options for treating carcinomas. People with carcinomas should speak with a doctor about treatment options. All images in this document came from http://www.voicemedicine.com/
