Vocal fold nodules are thought to be the result of vocal fold tissue trauma caused by excessive mechanical stress. [1] [2] [5] During phonation, the vocal folds undergo many forms of mechanical stress. One example of such stress is the impact stress caused by the collision between the left and right vocal fold surfaces during vibration. [2]
Voice therapy consists of techniques and procedures that target vocal parameters, such as vocal fold closure, pitch, volume, and quality. This therapy is provided by speech-language pathologists and is primarily used to aid in the management of voice disorders, [1] or for altering the overall quality of voice, as in the case of transgender voice therapy.
Practicing good vocal hygiene is recommended to prevent vocal fold cysts. [4] Initial treatment of the cysts involves voice therapy to reduce harmful vocal behaviours. If symptoms remain after voice therapy, patients may require surgery to remove the cyst. Surgery is typically followed by vocal rest and further voice therapy to improve voice ...
Vocal cord nodules and polyps are different phenomena, but both may be caused by vocal abuse, and both may take the form of growths, bumps, or swelling on the vocal cords. Vocal fold paralysis is the inability to move one or both of the vocal cords, which results in difficulties with voice and perhaps swallowing.
Vocal cord dysfunction (VCD) is a condition affecting the vocal cords. [1] It is characterized by abnormal closure of the vocal folds, which can result in significant difficulties and distress during breathing, particularly during inhalation. [1] Due to the similarity in symptoms, VCD attacks are often mistaken for asthma attacks or laryngospasms.
Vocal fold lesions such as a vocal fold nodule or other changes in the vocal fold mucosa can lead to increased tension in the larynx and cause dysphonia. [2] Larynogopharyngeal reflux, a process that is similar to GERD, can bring stomach acid into the larynx. This can provoke the larynx to tense to prevent the aspiration of the acid. [3]
Signs and symptoms may include hoarseness of the voice, or a sensation of having a lump in the throat, but contact granulomas may also be without symptoms. [3] There are two common causes associated with contact granulomas; the first common cause is sustained periods of increased pressure on the vocal folds, and is commonly seen in people who ...
Reinke's edema is the swelling of the vocal cords due to fluid collected within the Reinke's space. [2] First identified by the German anatomist Friedrich B. Reinke in 1895, the Reinke's space is a gelatinous layer of the vocal cord located underneath the outer cells of the vocal cord.
