Sulcus vocalis in monozygotic twins

Sulcus Vocalis (Type III): Prevalence and Strobovideolaryngoscopy Characteristics

“…7,12 Sunter et al 5 showed more SV in adult patients and no SV in patients aged younger than 15 years, but there are also studies reporting pediatric cases further confusing the issue. 1,13 It may be challenging to perform rigid SVL in children; thus, the diagnosis of subtle laryngeal findings like SV may be reported less frequently in the pediatric population. Variability in age and unknown etiology make defining a subject population difficult.…”

Histopathological Characteristics of Sulcus Vocalis

“…We were unable to detect sulcus in pediatric cases, in contradiction to the study by the same authors. 8 A larger population study may obviate the pediatric rates of sulcus vocalis and promote new evidence to understand its etiopathogenesis.…”

Sulcus vocalis: evidence for autosomal dominant inheritance

“…Others advocate a genetic origin, in which sulcus vocalis stems from embryonic defects in laryngeal development (Bouchayer et al, 1985). The latter has support from the findings of these lesions in monozygotic twins (Cakir et al, 2010) and in many members of the same family (Martins et al, 2007), found by our group in another family unrelated to the one presented here, and also from its association with other congenital laryngeal lesions, i.e., cysts, mucosal bridges and microwebs (Bouchayer et al, 1985;Pontes et al, 1994;Villagomez and Rosen, 2000).…”
