Resumen

El foramen mandibular es un importante hito anatómico. Para procedimientos como el bloqueo alveolar inferior del nervio, el tratamiento con implantes y osteotomías mandibulares, un profundo conocimiento de la ubicación del foramen mandibular (MF) y el foramen mandibular accesorio (AMF) es un requisito previo. Hay pocas referencias en la literatura con respecto a la localización anatómica exacta del foramen mandibular. Por lo tanto, el presente estudio tuvo como objetivo identificar la ubicación exacta de la MF y la incidencia de la AMF alrededor MF en una población india. Sesenta (60) mandíbulas humanas adultas fueron estudiadas para determinar la distancia del LV de la los anteriores, bordes posteriores de la rama mandibular, maxilar inferior categoría y el ángulo de la mandíbula. AMF todo el MF también fueron estudiados por su presencia y números. La distancia media de MF del borde anterior de rama mandibular fue 15,72 ±2,92 mm(lado derecho), 16,23 ±2,88 mm(lado izquierdo), de borde posterior fue 13,29 ±1,74 mm(lado derecho) y 12,73 ±2,04 mm(a la izquierda lado). La MF se encuentra 22,70 ±3 mm(lado derecho) y 22, 27 ± 2,62 mm(lado izquierdo) de la muesca mandibular. La distancia de MF de ángulo de la mandíbula fue 21,54 ±2,92 mm(lado derecho) y 21,13 ±3.43 mm(lado izquierdo). AMF estuvieron presentes en el 16, 66% de las mandíbulas. En 10% de las mandíbulas una sola AMF estaba presente y en el 6,66% hubo dos agujeros presentes. La ubicación del MF y AMF es importante para evitar compli-caciones como hemorragia y parestesia durante los procedimientos quirúrgicos orales y también para los radioterapeutas en la planificación de la radioterapia. 

 

The mandibular foramen is an important anatomical land mark. For procedures like inferior alveolar nerve block, implant treatment and mandibular osteotomies, a thorough knowledge of the location of the mandibular foramen (MF) and accessory mandibular foramina (AMFs) is a prerequisite. There are few references in the literature regarding the exact anatomical location of the mandibular foramen. Therefore, the present study was aimed to identify the precise location of the MF and the incidence of AMFs around MF in an Indian population. Sixty (60) adult human mandibles were studied to determine the distance of the MF from the anterior, posterior borders of the mandibular ramus, mandibular notch and angle of the mandible. AMFs around the MF were also studied for their presence and numbers. The average distance of MF from the anterior border of mandibular ramus was 15.72 ±2.92 mm(right side), 16.23 ±2.88 mm(left side), from posterior border was 13.29  ±1.74 mm(right side) and 12.73 ±2.04 mm(left side).The MF was located 22.70 ±3 mm(right side) and  22.27 ±2.62 mm(left side) from mandibular notch. The distance of MF from angle of mandible was 21.54 ±2.92 mm(right side) and 21.13 ±3.43 mm(left side). AMFs were present in 16.66% of mandibles. In 10% mandibles a single AMF was present and in 6.66 % double foramina were present. Location of MF and AMF is important to avoid complications like hemorrhage and paresthesia during oral surgical procedures and also for radiotherapists in planning radiation therapy.
