Vocal cord sulcus.
Vocal cord sulcus is a congenital condition consisting of a furrow on the medial edge of the vocal cord. It is most often bilateral but may be unilateral. The symptoms are a hoarse and breathy voice due to incomplete closure of the vocal cords. The present series comprises 15 patients found among 1,400 patients with voice and speech disorders. The condition is often overlooked and regarded as part of a primary functional hyperkinetic voice disorder. By close inspection the furrow can often be seen by indirect laryngoscopy. In many cases, however, microlaryngoscopy under general anaesthesia should be performed, but the furrow is only detected if a search is made for it. The condition is often found in younger patients, probably due to the fact that the sulcus is difficult to detect in older patients who have developed severe organic changes in a effort to overcome the incomplete closure of the glottis.
