上颌动脉本干走行隐蔽,其主要分支要经过骨性的孔、管、沟、裂走行,如该动脉本干要通过翼上颌裂进入翼腭窝;脑膜中动脉要通过颅底棘孔;下牙槽动脉要通过下颌孔、下颌管、颏孔;眶下动脉要通过眶下裂、眶下沟、眶下管、眶下孔;腭降动脉要通过翼腭管、腭大孔;蝶腭动脉经蝶腭孔、切牙管、切牙孔;上牙槽后动脉要经过牙槽孔、牙槽管。这些特点给常规解剖制作带来很大难度。为此,我们采用盐酸浸泡脱钙法制作上颌动脉及其分 The main artery of the maxillary arteries is stealthy. The main branches of the maxillary artery go through the bony holes, tubes, ditch and rupture. If the artery stems into the pterygopalatine fossa through the maxillary cleft, the middle meningeal artery passes through the spinous hole of the skull base. The alveolar artery passes through the mandibular foramen, the mandibular canal, and the mental foramen; the infraorbital artery passes through the inferior orbital fissure, the infraorbital foramen, the infraorbital foramen, the infraorbital foramen; Arterial transection of palate, incisor, incisor hole; the posterior sulcus artery to go through the alveolar hole, alveolar tube. These features bring great difficulty to conventional anatomy. To this end, we use hydrochloric acid soaking decalcification of the maxillary artery and its points
