Abstract:
The canalis sinuosus,a canal containing the anterior superior alveolar nerve bundle,originates from the infraorbital canal and extends along the maxillary sinus and nasal cavity edges to the anterior maxilla.It was once regarded as an anatomical variation.However,with the widespread application of cone beam computed tomography(CBCT),the detection rate of canalis sinuosus in the population has increased.The canalis sinuosus exhibits diverse courses,branching into multiple accessory canals and terminating at the nasal floor or the anterior tooth region,with the majority traversing the palatal side of the central incisor.The anterior superior alveolar nerve bundle within the canalis sinuosus not only innervates and nourishes the maxillary anterior teeth and the corresponding soft tissues,and the maxillary sinus mucosa,but also relates to the nasal septum,lateral nasal wall,and parts of the palatal mucosa.To minimize surgical complications,strategies for preventing and treating canalis sinuosus injuries need to be investigated.Preoperatively,CBCT is used to identify the canalis sinuosus and to virtually design implant placement at a distance of more than 2 mm from the canalis sinuosus.Intraoperatively,assessing bleeding and patient comfort,complemented by precision surgical techniques such as the use of implant surgical guide plates.Postoperatively,CBCT is used to examine the relationship between the implant and the canalis sinuosus,and treatment of canalis sinuosus injuries can be tailored based on the patient's symptoms.This review summarizes the detection of canalis sinuosus in the population,its anatomical characteristics,and the physiological functions in the anterior maxilla,and discusses strategies for avoiding canalis sinuosus injuries during implant surgery,thereby enhancing clinical awareness and providing references for clinical decision-making.
