“…The rate of septum presence in the maxillary sinus was reportedly over 30% in previous studies [1][2][3] . The etiology of the maxillary sinus septum has been hypothesized by several authors [3][4][5][6] . Uemura (1974) 6) considered that maxillary sinus septa were formed by pressure, such as that generated by chewing.…”

“…Subsequently, the height of each septum/bony bridge was measured in accordance with the method of Velasquez-Plata et al 15) In septum/bony bridge measurement, a reformatted image along a direction parallel to the mesio-distal axis of the dental arch was obtained, and the distance between the base and top of the septum/bony bridge was measured using an medio-lateral middle image of the septum/bony bridge. Moreover, the distance between the base of the septum/bony bridge and bony palate was superoinferiorly measured using a previous described method 3) . The angle between the direction of the septum/bony bridge and median palatine suture was measured on axial images using a previously reported method 3) .…”

“…Uemura (1974) 6) considered that maxillary sinus septa were formed by pressure, such as that generated by chewing. Also, 3) suggested that when disharmony due to the enlargement of sutures and deposition and resorption of the bone surface in the alveolar process and maxillary sinus occur, a maxillary sinus septum might be formed as a buttress to retain the volume and form of the maxillary sinus. However, the timing and mechanism of maxillary sinus septum formation have not been clarified.…”

Summary: Maxillary sinus septa and bony bridges were observed using dry skulls in childhood, classified based on Hellman's dental age, to clarify maxillary sinus septum formation.Eighty-eight maxillary sinuses of 44 dry skulls and a cone-beam computed tomography (CBCT) unit were used. The locations of the septum, defined as a pointed bony structure originating from the inferior wall, and bony bridge, defined as a bony structure between the maxillary sinus wall and dental germ, were antero-posteriorly recorded, and the superoinferior distance, distance from the bony palate, and angle to the median palatine suture were measured.The rate of septum presence in the maxillary sinus was high (41.7%) in IIIC, and the septa were located in the deciduous molars, premolars, and molars. Also, all bony bridges were related to the median maxillary sinus wall, and the rate of the maxillary sinus showing a bony bridge was high in IIA and IIIA.

There are no available detailed data on the three-dimensional courses of the human superior alveolar nerves and vessels. This study aimed to clarify the relationships of the maxillary sinus with the superior alveolar nerves and vessels using cone-beam computed tomography (CT) combined with l-CT and histological analyses. Digital imaging and communication in medicine data obtained from the scanned heads/maxillae of cadavers used for undergraduate/postgraduate dissection practice and skulls using cone-beam CT were reconstructed into three-dimensional (3D) images using software. The 3D images were compared with l-CT images and histological sections. Cone-beam CT clarified the relationships of the maxillary sinus with the superior alveolar canals/grooves. The main anterior superior alveolar canal/groove ran anteriorly through the upper part of the sinus and terminated at the bottom of the nasal cavity near the piriform aperture. The main middle alveolar canal ran downward from the upper part of the sinus to ultimately join the anterior one. The main posterior alveolar canal ran through the lateral lower part of the sinus and communicated with the anterior one. Histological analyses demonstrated the existence of nerves and vessels in these canals/grooves, and the quantities of these structures varied across each canal/groove. Furthermore, the superior dental nerve plexus exhibited a network that was located horizontally to the occlusal plane, although these nerve plexuses appeared to be the vertical network that is described in most textbooks. In conclusion, cone-beam CT is suggested to be a useful method for clarifying the superior alveolar canals/grooves including the nerves and vessels. Anat Rec,
