Branching pattern of mental nerves in south Indian population: A cadaveric dissection study
Journal Title: Indian Journal of Clinical Anatomy and Physiology - Year 2018, Vol 5, Issue 4
Abstract
Introduction Knowledge of branching pattern of mental nerve MN at mental foramen MF along with prevalence of accessory mental foramen AMF exhibiting accessory mental nerve AMN is an obligatory consideration in orthodontics like osteotomy reconstructive procedures placement of implants nerve blocks It has been reported to show population differences regarding these in various osteological studies However no cadaveric study is reported in South Indian population so farAim To analyze the branching pattern of MN at its emergence to determine the location of MF in relation to mandibular teeth and to study the frequency of occurrence of AMF with the structures emerging through it in South Indian populationMaterials and Methods 30 cadavers were dissected bilaterally exposing the mental foramen Terminal branches of MN at the foramen were carefully dissected and their distribution was noted The position of MFs and AMFs were noted in relation to mandibular teeth The AMN if present was carefully dissected and noted The mean distance between accessory mental foramen and mental foramen was also measuredResults A single MN was noted in all the cadaveric specimens n 60 The MN most commonly branched into two branches in 5166 of cases The location of MF was found to be inferior to the second premolar on either side in 66 cases The AMF with AMN passing through it was found only in 33 of casesConclusion The commonest pattern of MN observed was MN dividing into 2 branches at the MF Though high prevalence of AMF noted not all AMF exhibited AMNKeywords Mental foramen Accessory mental foramen Orthodontics Mental nerve Accessory mental nerve Nerve block
