摘要：

目的 探讨比格犬上颌窦正常解剖，为与上颌窦有关的动物实验提供解剖学依据。 方法 收集16个比格犬上颌窦，利用锥形束投照计算机重组断层影像（CBCT）扫描，并完成局部解剖，详细观察上颌窦形态、位置、容积、自然窦口位置及与周围组织的毗邻关系。另购买2只健康成年比格犬，利用CBCT确定上颌窦窦底，经腭侧开窗，显露软组织，夹取该位点黏膜行组织学检查，光学显微镜下验证所夹取黏膜是否为上颌窦黏膜。 结果 比格犬上颌窦形状略似锥形，前部较窄，后部宽大，位于上颌第3前磨牙与第1磨牙之间的腭侧，四周均有骨壁包绕。于第4前磨牙远中牙尖腭侧，距腭中缝约17～18mm处可见上颌窦最低点。同一个体双侧对比，差异无统计学意义。 结论 比格犬双侧上颌窦无明显差异，有利于上颌窦相关研究进行随机分组；窦腔内无明显骨嵴或分隔，降低窦黏膜穿孔的危险；行上颌窦外提升时，结合CBCT于上颌窦最低点经腭侧骨板开窗是最佳的术式。

Abstract:

Objective To investigate the anatomy of beagle dog’s maxillary sinus, and provide the anatomic data for animal study. Methods Sixteen maxillary sinuses of the beagle dog were collected and scanned by cone beam computerized tomography (CBCT). The morphology, position, volume, ostium of maxillary sinus as well as its relation to the adjacent tissues were examined. Two other health adult beagle dogs were used for histological examination in which after the preoprerational CBCT examination.A bone block in hard palate was surgicall lifted and the living mucosa tissue was sampled for histological examination. Results It was observed from CBCT that the shape of the maxillary sinus was nearly taper type which was stenosis in the front，spacious at the back. Maxillary sinus was located in the palate side between the maxillary third premolar and the maxillary first molar surrounded with bony. The maxillary sinus floor was in the palate side of the maxillary forth premolar, and was about 17-18mm distant from midpalatal suture. There was no obvious statistic difference in both side of same individual. Conclusion The characteristics of the bilateral maxillary sinus have no significant difference, and are conducive to make the randomly grouping design for maxillary sinus’s study; The rates of membrane perforation is reduced as for there is no bone crest or antral septa in sinus cavity. Sinus floor elevation in the right space by use of anatomic mark point in CBCT is able to accurately display the complete image of the maxillary sinus, and liftting bone block in hard palate of the the maxillary sinus floor is safer and more accurate, and more minimally invasive.
