Abstract
Introducción: Canalis Sinuosus (CS), canal intraóseo localizado en la región maxilar anterior (RMA), contiene elementos vasculonerviosos alveolares anterosuperiores. Surge del canal infraorbitario, desciende lateral a la cavidad nasal hasta el agujero septal. Puede presentar canales accesorios (CA) en su porción terminal. Diversas intervenciones en la RMA pueden comprometer al CS y/o sus CA, causando complicaciones. El CS es descrito como una variación anatómica (VA), pero presenta elevadas prevalencias, entre 51,7%-100%, cuestionándose esta aseveración. Objetivo General: determinar la prevalencia y características anatómicas del CS mediante Cone Beam CT en exámenes de pacientes chilenos realizados en el centro radiológico IMAPROX® entre los años 2017-2021. Objetivos Específicos: determinar la prevalencia del CS según sexo. Determinar la presencia uni o bilateral y diámetro mayor del CS. Determinar la presencia y número de CA. Metodología: estudio cuantitativo observacional descriptivo transversal, consistente en el análisis de 220 exámenes imagenológicos CBCT maxilares de pacientes chilenos
obtenidos del centro radiológico IMAPROX®, entre los años 2017 a 2021 provenientes de una base de datos anonimizada y que cumplieron con los criterios de inclusión/exclusión. Se realizó un análisis retrospectivo de todas las imágenes obtenidas considerando las variables sexo, presencia del CS, CS uni o bilateral, diámetro mayor del CS, presencia y número de CA, y un posterior análisis estadístico uni y bivariado. Resultados: se encontró un 100% de prevalencia del CS en ambos sexos, y se observó de forma bilateral en toda la muestra. El diámetro mayor promedio del CS fue de 2,58 mm. El 76,8% de la muestra presentó CA, siendo más prevalente la presencia de 2 CA con un 34,1%. Discusión: se describe que una estructura anatómica normal habitual (EANH) debe presentar sobre 50% de prevalencia para ser considerada como tal, sin embargo, no hay consensos en criterios empleados para definir VA o EANH. La literatura describe al CS como VA, pero estudios actuales muestran elevadas prevalencias en diversas poblaciones mundialmente. Se reportan prevalencias de 67% en Rusia, 88% Brasil y 100% en Turquía, Colombia y Chile. El presente estudio también encontró un 100% de prevalencia, sugiriendo que el CS es una EANH. Pese a ello, el CS es poco conocido y se asocia a numerosas complicaciones por procedimientos en la RMA, tales como cirugías, colocación implantes, microtornillos, etc., pudiendo generar hemorragias, parestesia/disestesia, dolor agudo, etc. Conclusión: las elevadas prevalencias reportadas en este y otros estudios sugieren que el CS es una EANH y no una VA, sin embargo, se requieren más estudios y consensos para definir si efectivamente es una VA o EANH. Es de relevancia clínica conocer la existencia y localización del CS para realizar procedimientos seguros en RMA, evitando complicaciones.
Introduction: Canalis Sinuosus (CS), an intraosseous canal located in the anterior maxillary region (AMR), contains anterosuperior alveolar vascular-nervous elements. It arises from the infraorbital canal, descends lateral to the nasal cavity to the septal foramen. It can present accessory channels (CA) in its terminal portion. Various interventions in the AMR can compromise the CS and/or its AC, causing complications. CS is described as an anatomical variation (AV), but it has a high prevalence, between 51.7%-100%, questioning this assertion. General Objective: determine the prevalence and anatomical characteristics of CS using Cone Beam CT in examinations of Chilean patients performed at the IMAPROX® radiological center between the years 2017-2021. Specific Objectives: determine the prevalence of CS according to sex. Determine the unilateral or bilateral presence and largest diameter of the CS. Determine the presence and number of CA. Methodology: cross-sectional descriptive observational quantitative study, consisting of the analysis of 220 maxillary CBCT imaging examinations of Chilean patients obtained from the IMAPROX® radiological center, between the years 2017 and 2021 from an anonymized database and who met the inclusion/exclusion criteria. A retrospective analysis of all the images obtained was performed considering the variables sex, presence of CS, unilateral or bilateral CS, largest diameter of CS, presence and number of AC, and a subsequent univariate and bivariate statistical analysis. Results: a 100% prevalence of CS was found in both sexes, and it was observed bilaterally in the entire sample. The mean largest diameter of the CS was 2.58 mm. 76.8% of the sample presented AC, the presence of 2 AC being more prevalent with 34.1%. Discussion: it is described that a usual normal anatomical structure (UNAS) must have a prevalence of over 50% to be considered as such, however, there is no consensus on the criteria used to define VA or UNAS. The literature describes CS as AV, but current studies show high prevalence in various populations worldwide. Prevalences of 67% are reported in Russia, 88% Brazil and 100% in Turkey, Colombia and Chile. The present study also found a 100% prevalence, suggesting that CS is an UNAS. Despite this, CS is little known and is associated with numerous complications from AMR procedures, such as surgeries, implant placement, microscrews, etc., which can cause bleeding, paresthesia/dysesthesia, acute pain, etc. Conclusion: the high prevalence reported in this, and other studies suggest that CS is an UNAS and not an AV, however, more studies and consensus are required to define whether it is indeed an AV or UNAS. It is of clinical relevance to know the existence and location of the CS to perform safe procedures in AMR, avoiding complications.
