Análisis morfogeométrico y trayectoria del conducto infraorbitario mediante tomografías Cone - Beam Guayaquil 2018.

Abstract

The infraorbital duct is located in the floor of the orbit leading to the suborbital foramen, where they travel the infraorbital nerve. Its identification is important to avoid iatrogenic injuries of the parcel neurovascular in Surgical Procedures. Objective: To analyze the shape, trajectory and position of the most prevalent infraorbital complex and determine which dental piece is in intimate relation with the infraorbital foramen. Materials and methods: a descriptive, observational and transversal study was carried out analyzing the morphogeometric structure of the infraorbital complex, measuring the length of the infraorbital complex, presence or absence of accessory ducts, distance between the infraorbital foramen and the infraorbital rim, channel pathway infraorbital and position of the infraorbital hole with teeth. Results: It was found that the classification of the most predominant infraorbital channel course is type I in men (63.2%) and in women (51.3%) Distance from the infraorbital foramen and the infraorbital rim that predominated was 6.0mm - 6.4mm (52.5%). Path distance of the most prevalent infraorbital duct was 26.9mm - 32.8mm (83.9%). The diameter of the most prevalent infraorbital hole was vertical 3.2 mm (90.7%) and horizontal 3.6 mm (64.4%) The presence of accessory ducts was 22, 9% absent and 77.1% present. The position of the infraorbital hole related to the teeth analyzed analyzed the second premolar was the one that prevailed with respect to the others in 48.3% Conclusion: The population studied was determined to be more predisposed to have type I classification of the course of the duct infraorbital, the dental piece most related to the infraorbital foramen is the second premolar, there is a low incidence of accessory ducts, the distance of the infraorbital foramen and the infraorbital rim 6.0mm and 6.4mm and the infraorbital duct course 26.9mm - 32.8mm.
