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.
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]
The swelling of the vocal folds cause ballooned-like appearance, known as a polyp. The polyps of Reinke's edema are usually benign, however, there may be a risk of cancer if the patient is a smoker. Additionally, if the edema becomes too severe, patients may experience difficulty breathing due to airway obstruction. [2] [12]
Most polyps are larger than nodules, which are more similar to callouses on the vocal folds. Polyps and nodules can exhibit similar symptoms including hoarseness or breathiness, "rough" or "scratchy" voice, harshness in vocal quality, shooting pain from ear to ear, sensation of having "a lump in the back of the throat", neck pain, decreased ...
Ligament vocal fold cysts- located within the deeper layers of the lamina propria or on the vocal ligament. [1] The symptoms of vocal fold cysts vary but most commonly include a hoarse voice and problems with the pitch of the voice. Vocal fold cysts are diagnosed based on gathering a case history, perceptual examination, and laryngeal imaging. [3]
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 ...
An autonomous thyroid nodule or "hot nodule" is one that has thyroid function independent of the homeostatic control of the HPT axis (hypothalamic–pituitary–thyroid axis). According to a 1993 article, such nodules need to be treated only if they become toxic; surgical excision (thyroidectomy), radioiodine therapy, or both may be used. [32]
The thyroid cartilage forms the bulk of the front wall of the larynx. It protects the vocal folds ("vocal cords"), which are located directly behind it. When the angle of the thyroid cartilage changes relative to the cricoid cartilage, this changes the pitch of voice. The cartilage also serves as an attachment for several muscles.
