Vocal cord nodules are bilaterally symmetrical benign white masses that form at the midpoint of the vocal folds. [1] Although diagnosis involves a physical examination of the head and neck , as well as perceptual voice measures, visualization of the vocal nodules via laryngeal endoscopy remains the primary diagnostic method.
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 ...
[8] [5] The vocal process is overwhelmingly the most common laryngeal site for these lesions, although they have also been observed on the medial and anterior portions of the vocal folds. [8] In nodule or polyp form, contact granulomas generally have a grey or dark red colouring [8] [5] and measure 2 to 15 mm in size. [5]
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]

These spots develop into harder, callous-like growths called nodules. The longer the abuse occurs the larger and stiffer the nodules will become. Most polyps are larger than nodules and may be called by other names, such as polypoid degeneration or Reinke's edema. Polyps are caused by a single occurrence and may require surgical removal.
The human vocal cords are roughly 12 – 24 mm in length, and 3–5 mm thick. [9] Histologically, the human vocal cords are a laminated structure composed of five different layers. The vocalis muscle, main body of the vocal cords, is covered by the mucosa, which consists of the epithelium and the lamina propria. [10]
