Radiological and Morphometric Features of Canalis Sinuosus in Russian Population: Cone-Beam Computed Tomography Study

Abstract

Introduction. Cone-beam computed tomography (CBCT) is considered to be the most informative radiographic method for pre- and postoperative analysis of the maxillary anatomy and for avoiding further complication. Canalis sinuosus is one of such structures that damage can go along with bleeding and neurological symptomatology. The aim of the study was to investigate radiological and morphometric features of the canalis sinuosus in Russian population using CBCT technique. Materials and Methods. 150 CBCT scans of 61 males and 89 females aged from 24 to 80 years were retrospectively studied with different slice thickness and evaluated with regards to prevalence and diameter among age and gender groups in Russia. Results. CS prevalence in this study was 67%, and CS was most frequently presented in the lateral incisor region (33.5%). Women showed statistically higher CS prevalence (p<0.01) than the male group, and there was no statistically significant difference observed between occurrence and localization of CS and age groups. Conclusion. CBCT examination demonstrated good diagnostic efficiency in CS visualization, and the CS may have variations on its location and prevalence with statistically significant differences between the gender group and without significant differences among age groups and can depend on the population.

Evaluation of location of canalis sinuosus in the maxilla using cone beam computed tomography

“…It is especially useful for CS research, as it can provide high resolution images and detailed three-dimensional scans 3,23 . Anatoly et al reported that the best visualization for detecting CS was achieved with 0.5 mm and 1 mm slice thickness slices 11 .…”

“…Sekerci et al 25 reported that the accessory canals were located most frequently palatal to the left lateral incisor. Anatoly et al 11 reported that CS was most frequently present in the lateral incisor region. Similarly, in our study, AC was most common in the region of the right and left lateral incisors, tooth 12 and tooth 22.…”

“…The published literature revealed great variability and differing results in the studies of the CS, highlighting the lack of standardization of the studies, and suggesting that results may depend on the slice thickness of the CBCT. The articles show that CS is an important structure, considering the neurovascular bundle it carries 4,11 .…”

“…Iatrogenic complications may occur especially in the area where the CS is located 6 . Therefore, this canal is one of the structures in which the damage can accompany bleeding and neurological symptomatology 11 . Olenczak et al reported that the ASAN is particularly susceptible to injury after mid-face fractures because its course is entirely intraosseous within the CS 1 .…”

Canalis sinuosus: An Anatomic Repair that May Prevent Success of Dental Implants in Anterior Maxilla

“…4,15 The CS is detected in 52.1% to 88% of all patients. 9,13,[16][17][18] Consequently, some studies have advocated that the CS might be considered to be an anatomic structure rather than an anatomical variation. 13,17 Nevertheless, even 81 years after it was first described, 3 the CS is still not well known by dental professionals.…”
