Bilateral dissections of maxilla were performed in a human adult cadaver head, male, aged 53 years. After the en block removal of the soft tissues in the oral and infraorbital regions, the antero-lateral surface of maxilla was exposed and also the vestibular aspect of the upper alveolar process. An oblique labially impacted right upper canine was evidenced, completely submucosal: its apex was tangent to the maxillary sinus floor, while the superior side of the apical part of the root was in close relation with the floor of the laterally expanded inferior nasal meatus. Superior and adjacent to the neck of that impacted canine a follicular cyst was evidenced and the antral wall presented distally to the apex of the impacted canine a dehiscent area, where the antral mucosa was only covered by an incomplete thin bony lamella. The incisors on that side were present but no resorption was identified at their level. Within the anterior border of the wall separating the maxillary sinus, small, and the inferior nasal meatus, the nerve for that impacted canine was coursing; the nerves for the upper incisors were initially located within the antero-lateral wall of the inferior nasal meatus. Although small, the maxillary sinus presented a supero-medial recess above the enlarged inferior nasal meatus and lateral to the normally-sized middle nasal meatus.
在一名53岁成年男性人类尸体头部进行了双侧上颌骨解剖。在整块切除口腔和眶下区域的软组织后，暴露了上颌骨的前外侧表面以及上牙槽突的前庭面。发现一颗右侧上颌尖牙唇侧倾斜阻生，完全位于黏膜下：其根尖与上颌窦底相切，而牙根根尖部分的上侧与横向扩大的下鼻道底部密切相关。在那颗阻生尖牙的颈部上方和相邻处发现一个滤泡囊肿，并且在阻生尖牙根尖的远侧，窦壁出现一个裂开区域，此处的上颌窦黏膜仅被一层不完整的薄骨板覆盖。该侧的切牙存在，但在其水平未发现吸收。在分隔上颌窦和下鼻道的壁的前缘内，有那颗阻生尖牙的神经走行；上切牙的神经最初位于下鼻道的前外侧壁内。尽管上颌窦较小，但在扩大的下鼻道上方、正常大小的中鼻道外侧有一个上内侧隐窝。
