The aim of this study was to conduct a systematic review of the frequency, location, diameter, variations in course, relationship to the course of the anterior superior alveolar nerve (ASAN), patient age and gender, and surgical implications of canalis sinuosus (CS), identified through imaging examinations, macerated skulls, or cadaver heads.
Medline, Scopus, and Web of Science databases were searched, and the retrieved articles were analyzed by 2 reviewers. The articles were selected by using well-established inclusion criteria. The Hawker scale was used for quality analysis. A kappa test was used to measure interobserver agreement.
The search identified 70 articles, of which 11 were selected for extraction and data analysis. Most studies consisted of cone beam computed tomography examinations of the location, diameter, and variable presence of accessory channels (ACs) in the CS. In total, 90.9% of the studies were of high or moderate quality.
The CS may present variations in its course, location, and diameter. It involves ASAN and a extension to the anterior palate region, the ACs. No statistically significant differences with regard to age or gender were discovered in the studies. Most articles report the relevance of the CS identification in surgical procedures close to the canal and emphasize the importance of awareness of the variable appearance of the CS.
本研究旨在对影像学检查、脱钙颅骨或尸体头颅中发现的上颌窦（CS）的频率、位置、直径、走行变异、与上前牙槽神经（ASAN）的关系、患者年龄和性别，以及手术意义进行系统综述。
通过 Medline、Scopus 和 Web of Science 数据库进行检索，由 2 位评审员对检索到的文章进行分析。通过使用既定的纳入标准选择文章。采用 Hawker 量表进行质量分析。使用 Kappa 检验来测量观察者间的一致性。
搜索确定了 70 篇文章，其中 11 篇被选作提取和数据分析。大多数研究包括对 CS 位置、直径和辅助通道（ACs）的变异存在的锥形束 CT 检查。总的来说，90.9%的研究质量较高或中等。
CS 可能在其走行、位置和直径上存在变异。它涉及 ASAN 并延伸到前腭区域的 ACs。在研究中未发现年龄或性别方面存在统计学差异。大多数文章报告了 CS 识别在靠近 CS 的手术过程中的相关性，并强调了认识 CS 可变出现的重要性。
