Topographic and Morphometric Anatomy of Mental Foramen of Black Bengal goat (Capra hircus) in Bangladesh with its Clinical Implication for Regional Anesthesia

The study was conducted to investigate the topographic and morphometric anatomy of mental foramen of Black Bengal goat. Total 20 mandibles from both sex of adult Black Bengal goat were studied. Mental foramen was always present at lateral aspect of the rostal part of body of each mandible with various shape, size and direction. Oval shaped and dorsolaterally directed mental foramen were predominant (85% and 80%) than the round shaped and laterally directed mental foramen (15% and 20%); respectively. The mean distance between lip commissure to mental foramen, base of body of mandible to mental foramen, 1st premolar tooth to mental foramen, lateral incisor tooth to mental foramen and caudal border of ramus of mandible to mental foramen were 2.37±0.09, 0.77±0.04, 1.46±0.09, 2.01±0.05 and 11.81±0.89 cm; respectively. Those topographic and morphometric anatomy of mental foramen of Black Bengal goat may helpful for veterinary surgeon to localize mental foramen easily for regional anesthesia during different surgical intervention of lower jaw.
