Document Summary

Overview: vocal nodule, polyp, cyst, granuloma, contact ulcer, infectious laryngitis, reflux laryngitis / lpr & gerd, presbylarynx, sulcus vocalis, reinke"s edema, leukoplakia, hyperkeratosis, papilloma, laryngeal web, cancer. Vocal nodules: description & etiology: inflammatory degeneration of the superficial layer of the lamina propria with associated fibrosis and edema. Typically form bilaterally at the anterior and middle two-thirds of the vf. Results from phonotraumatic behaviors (including loud talking, screaming, throat clearing, coughing, singing out of pitch, making unusual noises) Increased mass and stiffness of vocal fold cover. Hourglass closure pattern with decreased vibratory amplitude and mucosal wave: three types of nodules: Raspy, hoarse, and breathy voice, easily fatigues. Loss of vocal range (typically higher pitch range: management: Benign, lesions of superficial lamina propria; on middle 1/3 vf. Caused by acute or chronic vocal misuse (phonotrauma: voice characteristics: Voice therapy to reduce hyperfunction and vocal misuse. Granulomas develop over area of contact ulcer until cause is addressed.
