The occurrence of SVE in family groups and the preponderance of reports from specific geographical areas suggest a hereditary etiology. Our objectives are to audit the possibility of a geographical variability between SVE and SVO and to study the patterns of presentation and treatment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Following ethics clearance, a 3\u2010year retrospective case\u2010series review of the demographics of vocal fold sulcus was conducted at voice centers in India, USA, Germany, and Australia. Sulcus cases were noted with details of associated lesions, sex, performers, age, and treatment given.

A total of 160\/239 SVE and 64\/112 SVO were found in men. Sulcus of both types made up 20% of benign lesions in Sydney, 17% in Mumbai, which were significantly higher than New York (4%) and Germany (3.5%).
