The canalis sinuosus is a neurovascular canal, a branch of nerve of infraorbital canal, through which the anterior superior alveolar nerve passes and then leans medially in course between the nasal cavity and the maxillary sinus, reaching the premaxilla in the canine and incisor region. The purpose of this article is to report a case with the presence of canalis sinuosus, in order to alert and guide professionals and discuss the morphology of this anatomical variation avoiding trans- and postsurgical disorders in dental implants. A 51-year-old female was attended to in a radiology clinic, reporting paresthesia in the right upper lip region and painful symptomatology after the installation of an implant in the corresponding region. The case revealed the presence of canalis sinuosus in imaging exams. The knowledge of this anatomical variation is essential for professionals, because attention to this region prevents irreversible damage. Therefore, the use of imaging examinations is recommended during the planning stages and treatment and after surgery in patients undergoing surgery in this area.
