TOPOGRAPHICAL LANDMARKS FOR IDENTIFICATION OF MASSETERIC BRANCH OF MANDIBULAR NERVE – A CADAVERIC STUDY

Dr. Ariyanachi K

Abstract :

Masseteric nerve block technique is used for the reduction of dislocated mandibular condyles and for the treatment of masseter muscle pain. Masseteric neurectomy is employed as a treatment modality for benign masseteric hypertrophy. Recently, masseteric nerve is used for facial reanimation procedures.  However, it is not always easy to locate the nerve since the facial measurements on which some surgical approaches are based upon are variable. The aim of this study wasto gain an adequate knowledge regarding the topography of the masseteric nerve. The study was carried out in the Department of Anatomy, JIPMER from October, 2014 to March, 2016 after obtaining permission from the Post–Graduate Research Monitoring Committee and Institute Ethics Committee. Sixteen formalin fixed cadavers available for the undergraduate dissection were utilised for the study. After meticulous dissection, the masseter muscle and the masseteric nerve were exposed. The required measurements were taken using the digital vernier caliper. The results were statistically analysed for mean, standard deviation and range. The masseteric nerve was 16.15 ± 2.31 mm medial to the midpoint of the temporomandibular joint capsule immediately below the lower border of the zygomatic arch. The masseteric nerve was 15.87 ± 1.64 mm superior to the lowest point of the mandibular notch. In this study, constant, predictable bony landmarks have been considered to identify the masseteric nerve, which can be used effectively in clinical practice for better manipulation of the masseteric nerve.
