“…Bony structure of IOC was classified using the criteria employed by a previously reported study (7). According to the developmental features of bony walls, IOC was classified as a true canal (definite bony walls without any defect), a canal with patchy superior wall (superior wall consisted of bony islets, but complete bony walls in rest of the canal), as a groove (absence of superior wall).…”

“…Anterior -superior alveolar nerve (ASAN) branches from the ION at the level of the 1/3 anterior portion of the IOC and runs within a tiny canal, named as anterior -superior alveolar canal (ASAC) by Song et al (7). ASAC might join into IOC just before the opening of IOF, or may have a separate foramen (Fig 2).…”

Aims: The purpose of this study is to assess the anatomic features and variations of the infraorbital canal (IOC).Material and method: Digitally archived paranasal sinus computed tomography (CT) images of 492 IOC of 46 adult patients (mean age; 36.7 ± 24.4 year, M/F: 154/92) were retrospectively reviewed. Course and bony structure of the IOC, existence of anterior superior alveolar canal (ASAC) and number of the infraorbital foramen (IOF) were evaluated.Results: IOC was observed as a groove, without a superior wall, rather than a canal in the majority of the images (64%). Presence of a true canal was observed in the 23% of the images. IOC coursed along the superior -lateral wall of the adjacent maxillary sinus in 83% of images (n = 408). IOF was single in 88% of images (n = 433). ASAC was detected in 44% of the images (n = 216). In comparison to IOC, ASAC had a lateral (n = 135, 62.5%) or inferior (n = 81, 37.5%) course. In the 72.6% of the patients presenting with ASAC, conjunction with IOC was detected just before the IOF.Conclusion: Anatomic features of IOC should be demonstrated in the patients who need orbital, maxillary sinus or dental implant surgery to prevent iatrogenic trauma to neurovascular bundles within. CT can provide accurate data in the evaluation of IOC anatomy, and correlative anatomical studies would strengthen the imaging. Bulgular: İOK incelemelerin çoğunda (%64) kanaldan çok oluk olarak görüntülenmiștir. Görüntülerin %23'ünde gerçek bir kanal görülmüștür. İOK, görüntülerin %83'ünde (n = 408) komșu maksiller sinüsün süperior-lateral duvarı boyunca seyretmiștir. Görüntülerin %88'inde (n = 433) tek İOF izlenmiștir. ASAK, görüntülerin %44'ünde (n = 216) mevcuttur. ASAK, İOK'nın lateralinde (n = 135, %62.5) ya da inferiorunda (n = 81, %37.5) görülmüștür. ASAK'ın görüldüğü olguların %72.6'sında ASAK ve İOK, İOF'nin hemen öncesinde birleșme göstermektedir.Sonuç: İçerisindeki nörovasküler yapıların iyatrojenik travmalardan korunması amacıyla orbital, maksiller ve dental cerrahi öncesi İOK'nın anatomik özelliklerinin ortaya konması gereklidir. İOK anatomisinin değerlen-dirilmesinde BT doğru bilgi sağlayabilmektedir. Görüntüleme bulgularının anatomik çalıșmalar ile korelasyonu görüntülemenin değerini arttırabilir.

“…The presence of the bony canals of the PSAA with AC may pose a risk during surgical treatments with drilling the alveolar bone on the MS. The IOA and PSAA have supplied to the MS in monkey (Matsukawa, 1969 (Song et al, 2012). Therefore we need to gain information about PSAC for avoid clinical risks using animal model.…”

Summary: The posterior superior alveolar canal (PSAC) composed of several canals which contains vessels and nerve in molar region of the maxilla of Japanese macaque. The PSAC of maxilla run to the maxillary sinus. However, the PSAC and accessory canal (AC) of the maxilla in the Japanese macaque (JM) is unknown in morphological features in the maxilla. The purpose of this study was to describe the PSAC of the primates and to determine whether this structure could be used as a model for the human clinical condition. In this study, we showed the course of PSAC structure of the 23 JMs (male: n = 15; female: n = 8) using a cone-beam computed tomography apparatus. In the results, we classified a type to have one AC toward, a type to have two ACs toward, and three ACs in a type to have in PSAC. The main canal have some bony branch canals (BBCs) composed of 3 types (no BBC, one BBC, two BBCs). These canals and they run downward and supply to MS, these roots of maxillary molar region of the craniofacial skeleton in contrast to numerous small accessory canals with no nerve and vessels observed in the posterior regions in maxilla. These morphology features may give useful information about MS in dental treatment human model.

This study aimed to determine the number of infraorbital foramina in monkeys of the Papionini tribe. The authors performed a μCT analysis of the morphology of the infraorbital foramina. A total number of 52 simian skulls belonged to two macaque species: Macaca mulatta and Macaca fascicularis were used in the study. The number of infraorbital foramina was counted macroscopically and with the use of a magnifying glass. Next, the skull representing the most common morphological type was selected and scanned by micro‐computed tomography (μCT). The Shapiro–Wilk normality test was used in the study. To compare the differences in the number of infraorbital foramen between species, sex and sides, the Mann–Whitney U test was applied. Three infraorbital foramina were present in most individuals from the test group. The Mann–Whitney test revealed no statistically significant difference between the number of foramina on the right‐ and left‐hand side. Likewise, no statistically significant differences between the numbers of infraorbital foramina across sexes were observed. Volumetric reconstructions revealed the presence of separate infraorbital canals for each infraorbital foramen. Craniofacial innervation in macaques is formed by complex branching patterns of cranial nerves. Variability in the number of infraorbital foramina suggests a variable maxillary innervation pattern in these animals. Based on the analysis of volumetric projections, the presence of two labial branches and a single nasal branch of the infraorbital nerve is suggested. Detailed descriptions are supported by quantitative data and μCT evidence.
