Rezumat:

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.
