Applied Anatomy of the Maxillofacial and Mandibular Regions of Indian Mithun (Bos frontalis) and its Clinical Significance in Regional Anesthesia

Abstract

Background: The topographic and morphometric anatomy of various foramina provides an easy approach in performing nerve blocks by their proper tracking for regional anesthesia in surgical interventions. There is no previously reported information on the applied anatomy and clinical significance of the maxillofacial and mandibular regions of the Indian mithun. The present study was designed to provide important clinical landmarks related to tracking of the infraorbital, mental and mandibular nerves with its clinical significance in regional anesthesia in mithun. Methods: The study was conducted on the maxillofacial and mandibular regions of twelve (n=12) adult Indian mithun of either sex (n=6, male and n=6, female). The head region samples of naturally died mithun were collected from different parts of the Mizoram and Nagaland state of India and processed as per the standard maceration technique. Altogether, a total of twelve measurements were taken in the maxillofacial and mandibular regions of mithun by using a digital vernier caliper and the results were expressed as mean±standard deviation. The obtained parameters from the present study can be useful for an extraoral and intraoral approach for nerve block of the infraorbital, mental and mandibular nerve in the maxillofacial and mandibular regions of mithun. Result: The present study revealed that all the obtained parameters related to regional anesthesia showed a significant statistical difference (P less than 0.01** and P less than 0.05*) between the males and females of mithun. It can be concluded from the present study that the various applied parameters of the present study will aid the clinicians in the implication of regional anesthesia in the head region of mithun.
