The maxillary artery (MA) passes over the lateral pterygoid muscle in infratemporal fossa and enters pterygopalatine through pterygomaxillary fissure. Refractory epistaxis is managed by ligation of sphenopalatine via a transmaxillary-transantral approach; there considerable risk complications associated with such invasive surgical approaches. aim this study was to describe gross anatomy variations therein MA its branches at fossa. One hundred hemifaces embalmed Korean adult cadavers were dissected establish precise course branching patterns. average thickness posterior wall sinus 0.8 mm, but varied wide range from 0.2 3.6 mm. We classified third part into 3 morphological categories: looped (61%), bifurcated (19%), straight (18%). Two cases could not be any these categories. pattern bifurcation between descending palatine arteries 4 types: Y intermediate (36%), M (17%), T (28%). divided 9 sections. areas most frequently (62% cases) located top medial partition middle (30% cases).
