Description
Summary:This work aimed to study the morphology of the mandibular canal in Computed Tomography (CT scans), in order to assist in the clinical and surgical management of dental interventions in the mandible area. The material used was composed of 377 CT scans, selected by age (between 15 and 80 years), obtained during the period from 2011 to 2013, belonging to a private practice radiology of the city of Caruaru-PE, Brazil. 96 of these met the inclusion criteria, with 37.5% male and 62.5% female. Concerning the form of the mandibular canal, all images presented: a single canal, bilateral, extending from the mandibular to the mental foramen, without any morphological change. 37.5% had mandibular canals classified as type I, 22,92% canals type II and III and 16,66% canals type IV Thus, we emphasize the importance of knowing the anatomy of the mandible as well as the path of the inferior alveolar nerve by the mandibular canal, especially to perform the various procedures that are performed in this region in order to minimize injury to the neurovascular bundle. KEY WORDS: Anatomy; Mandible; Computed tomography. El objetivo fue estudiar la morfologia del canal mandibular en la tomografia computadorizada (TC), con el fin de ayudar en el manejo clinico y quirurgico de las intervenciones dentales en el area de la mandibula. El material utilizado incluyo 377 TC, seleccionadas por edad (entre 15 y 80 anos), obtenidas durante el periodo 2011- 2013 desde el banco de datos de una clinica privada de radiologia en la ciudad de Caruaru-PE, Brasil. Noventa y seis TC cumplieron los criterios de inclusion (37,5% hombres y 62,5% mujeres). En relacion a la forma del canal mandibular, todas las imagenes presentaron un solo canal, bilateral, que se extiendio desde el foramen mandibular hasta el foramen mental, sin ningun cambio morfologico. En el 37,5% de las TC hubo canales mandibulares clasificados como Tipo I; en 22,92% tipo II y III. Solo el 16,66% presento canales tipo IV Destacamos la importancia de conocer la anatomia de la mandibula, asi como el trayecto del nervio alveolar inferior en el canal mandibular, especialmente para la realizacion de los diversos procedimientos en esta region con el fin de minimizar el dano a los haces neurovasculares.
