Vocal cord nodule is a mass of tissue that grows on the vocal folds (vocal cords). Typically, this mass will appear on the junction of the anterior 1/3 and posterior 2/3 of the vocal fold, where contact is most forceful. A vocal cord nodule reduces or obstructs the ability of the vocal folds to create the rapid changes in air pressure which generate human speech. Symptoms include hoarseness of speech, painful speech production, frequent vocal breaks, and reduced vocal range. Vocal fold nodules develop mostly in adult females, and children of both sexes.Scholarly peer review is the process of subjecting an author's scholarly work, research, or ideas to the scrutiny of others who are experts in the same field, before a paper describing this work is published in a journal. The work may be accepted, considered acceptable with revisions, or rejected. Peer review requires a community of experts in a given (narrowly defined) field, who are qualified and able to perform reasonably impartial review.
