Maxillary Swing Approach Of The Relevant Anatomy

Objective(1) The best approach knocked on the exposed jaw of all anatomical structures and relationships of the restrictions imposed.for the introduction of the surgical treatment of lesions of the corresponding anatomical anatomy of visual information delivery system:(2) The maxillary approach involving overturned by the shallow and deep level of each layer all the surgical approach associated with important anatomical structures and signs;(3) measuring the distance between important anatomical landmarks and important blood vessels and nerves of the diameter, the surgical approach to provide the morphological signs:(4) The variation of vascular surgical approaches and postoperative effects. Methods40 sides of 20 cases of adult male cadaver fixed by local dissection anatomy layer by layer separately,outside of the five branches of the facial nerve to the level of the pterygopalatine fossa and medial to the nasal fossa level layers of anatomy;hrown into the road of maxilla exposed parapharyngeal space and infratemporal fossa,and other important anatomical structures:After perfused with red latex used for vascular studies clearly show that this surgical approach involving major blood vessels and blood supply;Use of natural etching important;network in the head and face,more intuitive display for the prevention of maxillary necrosis after surgery to provide anatomical information;Using vernier calipers on the important anatomic landmarks for measurement;Head in the simulated body thrown into the road on the observation of maxillary exposed anatomic regions and relevant important artery course.Results(1) clear the nasal lateral wall,butterfly ethmoid, skull base.cavernous sinus.pterygopalatine fossa,infratemporal fossa,parapharyngeal space,and other important details of anatomical structure shape,boundaries.and take the line of adjacent neurovascular;(2) defined by the maxillary thrown into the road after the important anatomical level;(3) clear overturned approach maxillary major blood vessels involved in the specific area Traveling and disposable.while observing the traffic area adjacent vascular and vascular network;(4) found a case of variations on the facial artery.This study was thrown into the road on maxillary comprehensive and systematic anatomical study reached the following conclusions: 1.Maxillary thrown into the road to expose the anatomical structure:the nasal cavity lateral wall, butterfly screen area,the base of the skull and the anterior skull base, cavernous sinus,nasopharynx.parapharyngeal space.pterygopalatine fossa.infratemp oral fossa.2.The temporal fossa and the base of the skull through the foramen ovale and the mandibul-ar nerve to go the line of traffic;fossa and skull base through the hole and take the line of the ma-xillary nerve traffic,so the infratemporal fossa and pterygopalatin fossa lesions easily penetrated cranial End.3. Maxillary overturned artery incision can damage the nose,but issued a nose for the facial artery before the artery has no effect,so the surface of the maxillary artery can be overturned as an important postoperative facial artery.4.The infraorbital artery in maxillary overturned the whole process can be retained. it is not overturned if the angle is too large lesions,can keep the infraorbital artery as a feeding artery of the face,should the disease need overturned angle.can be Do find the infraorbital artery ligation. avoiding the process knocked major bleeding.5.Sphenopalatine artery is divided into two,which overturned septal artery in the process will inevitably damage the posterior lateral nasal artery intact after the thrown.it can be used as nasal cavity lateral wall of the artery,If the surgery too much damage,can be found in the overt-urned before doing this artery ligation to prevent excessive bleeding during overturned.6.maxillary artery from the external carotid artery, the top issue of the mandibular buccal artery suddenly chin and move outside the lines laid down,the control of buccal muscles.The maxillary artery is located outside of the impact of not overturned,it can serve as a postoperative facial artery.7.in the head and face of the vascular cast of the superficial surface of the mandible can be seen that the deep surface of the masseter muscle has a rich capillary network.this area adjacent to the maxilla,while in the maxillary lateral, not overturned the imp- act of Can serve as a posto-perative facial blood supply is another important area;at the top of the zygomatic arch. the temp-oral fossa.and a rich vascular network, from the jaws close,can be overturned in the maxillary ar-tery after a region.8.perfused with red latex corpse case of right external carotid artery in the first issue of the facial artery, the issue before the transverse facial artery in two arteries to issue a new artery,wal-king down the line at the top level of the mandibular angle to the forward Slightly lateral to the mental foramen number of support were given disposable cheek muscles,the lower orbicularis o-ris,the mentalis muscles,and with the infraorbital artery,facial artery communicating branch bet-ween the rich anastomosis.The facial artery after bypassing the mandibular angle,up to the chin hole,the control of the muscles in the region,not to continue upward.The left side of the upper lip artery artery above the level of the right upper lip had been walking along the line,beyond the right side of the mouth near the right side of the upper lip artery absent.
