OTHER STRUCTURAL DISORDERS

Sulcus vocalis, Presbylaryngis, Laryngeal burns, Ankylosis of cricoarytenoid joint, Subglottic stenosis, Laryngomalacia, Laryngeal cleft, Varix and Ectasia and vocal fold hemorrhage

Sulcus vocalis

a groove on surface of medial vocal fold, unknown etiology, hoarseness;increased vocal effort; fatigue

Presbylaryngis

Aging voice; thinner, less pliable tissue in vocal cords as they ossify;becomes denser; altered pitch

Laryngeal burns

chemical exposure or inhalation burns on vocal folds; orally or by smell; laryngeal structures swell, maybe blister; can impact vocal cord function or even breathing; weak hoarse voice to no voice; pain when swallowing; will heal in time

Ankylosis of cricoarytenoid joint

stiffness/fusing of the joint, maybe caused by arthritis, effects vocal quality

Subglottic stenosis

narrowing of airway, acquired if long time intubated, or often associated with malformed craniocartilage occurring in utero, exhalation/inhalation difficulty/strider, low pitch cough, hoarseness/breathiness

Laryngomalacia

collapse of laryngeal cartilages, seen in infants;scary, but will be grown out of

Laryngeal cleft

very rare, may narrow the airway, occurs with cricoid cartilage, results in mal formation posteriorly, exhalation/inhalation stridor

Varix and Ectasia and vocal fold hemorrhage

Vascular lesions, direct result of phonotrauma, more prevalent in women than men
