Anatomy Research Of The Nasal Cavity And Sinuses Related To Endoscopic Surgery

Purpose:Through cadaver head dissection, make sure the location, shape Pattern, Variation and Close relationship of the nasal main anatomy Structure, Investigate the anatomical significance of various structure in endoscopic surgical procedures, provide the basis for making the personalized surgery program, and at the same time make a complete set of nasal anatomy atlas, which is full of independent intellectual property rights and related to endoscopic sinus surgery.Method:Finely dissect and study the cadaver head, in accordance with established methods. Analyze the location, shape, and close relationship of the nasal cavity and the relevant region. With the specialized equipment, multi-directionally shoot the structure related to the nasal cavityResults:Define the detailed shape, location, boundaries, adjacent and so on of the anatomical structures related to endoscopic ostimeatal complex region surgery, Frontal sinus region surgery, the region surgery related to Nose and eye, sella turcica region surgery, Pterygopalatine fossa region surgery and Infratemporal fossa region surgery.Conlusion:1.The bottom type attach to the uncinate process and the fontanelle type, uncinate process Variation,ethmoidal bulla and lateral sinus pneumatolysis type, base lamella of the middle turbinate form, concha bullosa,Haller cell are the main structure of the ostimeatal complex regional surgery location and careful operation.2.The important structure in the Frontal sinus region surgery, such as superior attachment of the uncinate process,Frontal recess form,agger nasi cell and cell related to Frontal recess region, have an effect on the surgery operation.3.Defining the join between Frontal process of maxilla and Lacrimal bone, the relationship between Nasolacrimal duct and agger nasi cell, the relation among lamina papyracea,medial rectus,optic nerve,ethmoidal sinus with sphenoidal sinus, the relationship between optic nerve and ophthalmic artery play a significant guidance sense on the surgery related to nose and eye.4. In the Endoscopic Endonasal Transsphenoidal sella turcica regional surgery, the location of opticocarotid recess has a better significant sense than that of optic nerve protuberance or internal carotid artery protuberance. And the sellar bulge is the important mark of the sphenoidal sinus midline. Meanwhile, internal carotid artery, ophthalmic artery, and the second to sixth pairs of Brain Nerve pass through sphenoidal sinus Lateral wall and so that we must ensure that the anatomy structure in the surgery, avoiding the corresponding complication caused by injury.
