Abstract
Background: The maxillary artery supplies the deep structures of the face and cranium. The maxillary artery and the mandibular nerve form a clinically important relation in the infratemporal fossa. Variations of the maxillary artery may complicate dental, oral, and maxillofacial surgeries in this region. Methods: During routine academic dissection of a 91-year-old Caucasian female cadaver, the pterygoid segment of the left maxillary artery was found medial to the posterior division of the mandibular nerve in the infratemporal fossa. Results: The maxillary artery coursed superior to the point of division of the mandibular nerve and remained undivided. Conclusion: This rare unilateral variation will be of interest to anatomists and clinicians, as an understanding of anatomical variations of the maxillary artery can help decrease the risk of hemorrhage and other surgical complications. KEY WORDS: Maxillary artery, Mandibular nerve, Lateral pterygoid muscle, Infratemporal Fossa.
