Description
Summary: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. KEY WORDS: Vomeronasal organ; Human; Anatomy. El organo vomeronasal se describio por primera vez en seres humanos en el siglo XVII. Tiene una funcion quimiosensorial y se encuentra en la mucosa del tabique nasal de los mamiferos. y consta de una abertura en la mucosa en la base del tabique nasal. Para este estudio, 143 individuos fueron estudiados mediante nasofibrolaringoscopia, y la presencia del organo vomeronasal se considero un hallazgo del examen. Tres tipos morfologicos de organo vomeronasal se observaron: fisura, foseta y circular, siendo el tipo foseta es mas comun en los hombres y las fisuras entre las mujeres. La prevalencia total del organo vomeronasal entre estos pacientes fue de 28% (40 pacientes). La prevalencia del organo vomeronasal de la poblacion en estudio es compatible con lo que ha sido reportado en otros estudios. PALABRAS CLAVE: organo vomeronasal; Hombre; Anatomia.
