Study on the Morphology and Frequency of the Vomeronasal Organ in Humans

Abstract

The vomeronasal organ was first described in humans in the seventeenth century. It has a chemosensory function and is found in the mucosa of the nasal septum of mammals and consists of an opening in the mucosa at the base of the nasal septum. For this study, 143 individuals undergoing nasofibrolaryngoscopy were studied, and presence of the vomeronasal organ was considered to be a finding from the examination. Three morphological types of vomeronasal organ were observed: fissure, fossette and circular. The total prevalence of the vomeronasal organ among these patients was 28% (40 individuals). The prevalence of the vomeronasal organ in this study population is compatible with what has been reported in other studies. The forms of the vomeronasal organ can be characterized: fissure, fossette and circular. The fossette type is commonest in males and the fissure among females.

“…Although a constant incidence has been found in different adult populations around the world (Bulgaria, Canada, Egypt, France, Mexico, and the United States of America), studies have shown it to be present (at least unilaterally and predominantly on the left side) in around one third of the population [ 9 - 11 , 15 - 18 ]. Reports suggest that it is more commonly found in children [ 6 , 16 - 18 ].…”

Reports suggest that it is more commonly found in children [ 6 , 16 - 18 ]. Some studies claim that it is present in over two-thirds of young people, with an increased incidence bilaterally, whilst other researchers suggest that it is present on both sides of the septum in almost all newborn babies [ 14 , 18 - 19 ].…”
