Knowledge of variations in arteries and nerves of infratemporal fossa may be helpful in radical neck dissection and in dental procedures to avoid the complications. We present an unusual case in which maxillary artery was found deep (medial) to lateral pterygoid muscle. Lingual nerve originated from two roots: anterior and posterior. Anterior root originated from common trunk and the posterior root directly from mandibular nerve. Inferior alveolar nerve was a continuation of the common trunk. Branches of mandibular nerve formed a loop through which passed the second part of maxillary artery. The clinical significance of the present variations has been discussed.
