| Objective：Research the position and distribution of accessory nasal cavity ostiumand circumjacent structures.Use the structures as the investigative object whichcan be used for a marker by mycteric endoscope. Measure the correlative dataabout the accessory nasal cavity ostium and marker so as to find the way to fixthe ostium and important marker. Providing the anatomical basis for lateralwall of the nasal cavity structure for clinical endoscopic findingMaterials and Methods：Select40anult cadaver heads(80cases) which have been fixed byformalin,with27male and13famale.There are not surgical trauma,ormationand operating ransform,all of them are without age.

The distance between the ostium and the head and end ofuncinate process.are4mm and13mm. Go straight through apertura maxillaries about8mm,we can pass the narrow endostoma maxillaries,and go intomaxillary sinus.(2) Ucinate process，nasoturbinal concha and ethmoidal bulla are allsituated in middle antrum region. Ucinate process is at inferior part and parallelwith middle nasal concha. nasoturbinal concha and ethmoidal bulla are situatedat anterior superior and posterior superior part of ucinate process. Clearpositioning on the three elements is a great significance about opening theoperation field and removing the specific structures(3) There is a significance about fixing the anterior region of sphenoidalostium,which can be used to define and find the aperture of sphenoidal sinusand surrounding structures.This research provide an anatomic basis for findingaperture of sphenoidal sinus and discriminate between aperture of sphenoidalsinus and posterior ethmoid sinus ostium.(4) Aperture of frontal sinus is in a naeeow gap which make up by thehead of uncinate process, the anterior wall of ethmoidal bulla and nasoturbinalconcha.It can be used to fix the aperture of frontal sinus,which is the distancebetween the aperture and the three apexes.This method provides an anatomicbasis for fixing the ostium under the mycteric endoscope,and it have a guidancefor clinical operation. |
