摘要
目的通过对藏酋猴上颌窦的应用解剖,为上颌窦的临床应用提供形态学依据。方法对6只藏酋猴的12侧上颌窦进行大体解剖,从整体和局部对上颌窦的位置、形态,窦腔与眶、鼻腔和口腔的结构进行观察和测量。结果藏酋猴的上颌窦位于上颌骨体内,由前、后窦构成。后窦位于前窦的后方,窦腔较小。前窦和人的上颌窦类似,位于第1前臼齿至第2臼齿及相应骨腭的上方,毗邻眶、鼻腔、口腔,窦腔较大且形态无异常;窦腔与眶间骨质较薄,有鼻泪管连通,其管径为(4.31±0.10)mm、长度为(15.89±0.31)mm;窦腔底与鼻腔间有大且恒定的上颌窦裂孔,自然状态下裂孔长度(12.59±0.46)mm、高度(1.01±0.12)mm;向上牵拉海绵状血管球可使裂孔高度增大到(11.14±1.44)mm;窦腔与口腔间骨质最厚处位于第1前臼齿根尖的上方,厚度为(6.20±0.20)mm,最薄处位于第2臼齿根尖的上方,厚度为(1.57±0.23)mm,窦底最低处位于第1、2臼齿间。同一个体双侧对比,差异无统计学意义。结论藏酋猴上颌窦的形态结构特点,适合于作为动物模型,应用于人类上颌窦病变、上颌窦提升及种植牙的相关研究;其上颌窦裂孔是上颌窦底非开窗手术入路的最佳部位。
Objective To provide morphological basis for the clinical application of maxillary sinus in Macaca Thibetana.Methods Twelve lateral maxillary sinuses of 6 Macaca Thibetana were dissected,and the position and morphology of maxillary sinuses,sinus cavity,orbit,nasal cavity and oral cavity were observed and measured.Results The maxillary sinus of macaca Thibetana was located in the maxilla.The posterior sinus was located behind the anterior sinus and the sinus cavity was small.The anterior sinus was similar to the human maxillary sinus,which was located on the upper part of the first premolar to the second molar and the corresponding bone palate,adjacent to the orbit,nasal cavity and oral cavity.The sinus cavity and the interorbital bone were relatively thin,connected by the nasolacrimal duct,whose diameter and length were(4.31±0.10)mm and(15.89±0.31)mm.There were large and constant holes in the maxillary sinus between the sinus cavity and the nasal cavity,with the length of the holes(12.59±0.46)mm and the height(1.01±0.12)mm in the natural state.The hiatal height increased to(11.14±1.44)mm when the cavernous vascular ball was pulled upward.The thickest bone between the sinus cavity and the oral cavity was above the root tip of the first premolar,and the thickness was(6.20±0.20)mm,the thinnest bone was above the root tip of the second molar,and the thickness was(1.57±0.23)mm,and the lowest sinus floor was between the first and second molars.There was not statistically significant difference between the two sides of the same individual.Conclusion The morphological and structural characteristics of maxillary sinus of macaca Thibetana are suitable to be used as an animal model for the study of maxillary sinus lesions,maxillary sinus elevation and dental implant in humans.The maxillary hiatus is the best site for the nonfenestration approach to the maxillary sinus floor.
