Familial Sulcus Vergeture: Further Evidence for Congenital Origin of Type 2 Sulcus.

A 29-year-old otherwise healthy woman presented with a lifetime history of hoarseness because it had begun to interfere with her career. Examination of both the woman and her 60-year-old father revealed bilateral sulcus vergeture, without inflammation or lesions attributable to phonotrauma. The woman responded well to injection augmentation; the father declined treatment. Combined with existing descriptions of other family groupings, all with sulcus vergeture without signs of inflammation, clinical progression, and little or no apparent behavioral component, this report further suggests that sulcus vergeture (Ford type 2) and sulcus vocalis (Ford type 3) are entirely different entities, despite architectural similarity.
