A degenerative lesion consisting of the empty “pocket” of what was formerly a cyst under the mucosa of the vocal cord. The lips of a glottic sulcus may be seen faintly during laryngeal stroboscopy. Or, vibratory characteristics may suggest this lesion.
A glottic sulcus may be overlooked unless one is familiar with this entity. To paraphrase eminent French laryngeal microsurgeon Dr. Marc Bouchayer, these lesions are diagnosed much more frequently once you know about them than before. At present, aside from having the patient coexist peacefully with this problem via voice therapy and other measures, surgery is the primary treatment modality.
