One of the major perceptual signs of vocal fold nodules is a change in the quality of the voice. [1] The voice may be perceived as hoarse, [4] [5] due to aperiodic vibrations of the vocal folds, [5] and may also be perceived as breathy, [4] [5] due to an incomplete closure of the vocal folds upon phonation.
Diplophonia is a result of vocal fold vibrations that are quasi-periodic in nature. [2] It has been reported from old days, but there is no uniform interpretation of established mechanisms. [ 3 ] It has been established that diplophonia can be caused by various vocal fold pathologies, such as vocal folds polyp , vocal fold nodule , recurrent ...
Voice disorders [1] are medical conditions involving abnormal pitch, loudness or quality of the sound produced by the larynx and thereby affecting speech production. These include:
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]
Laryngologists treat disorders of the larynx, including diseases that affects the voice, swallowing, or upper airway. Common conditions addressed by laryngologists include vocal fold nodules and cysts, laryngeal cancer, spasmodic dysphonia, laryngopharyngeal reflux, papillomas, and voice misuse/abuse/overuse syndromes.
Vocal fold imaging techniques are used by clinicians to examine the vocal folds and allows them to detect vocal pathology and assess the quality of the vocal fold vibrations. Laryngeal stroboscopy is the primary clinical tool used for this purpose.
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 injuries can have a number of causes including chronic overuse, chemical, thermal and mechanical trauma such as smoking, laryngeal cancer, and surgery. Other benign pathological phenomena like polyps, vocal fold nodules and edema will also introduce disordered phonation. [34]
