“…Furthermore, Sekerci et al13 analyzed the presence of the accessory foramina and canals having a diameter of at least 1 mm within the premaxilla in 368 pediatric patients using CBCT. Eighty-two patients had additional canals; in 6 of them, the canals presented as a direct extension of the CS.…”

PurposeThe nasopalatine canal is a well-known, important anatomical structure in the anterior maxilla, but this region contains many accessory canals. The canalis sinuosus (CS) is one of these canals; it contains the anterior superior alveolar nerve, along with veins and arteries. The purpose of this study was to evaluate the CS using conebeam computed tomography (CBCT) in patients with maxillary impacted canines.Materials and MethodsA total of 111 patients admitted to the Istanbul Medipol University School of Dentistry for the exposure, orthodontic treatment, and/or extraction of an impacted canine were included in this study. CBCT images were obtained for these patients under standard conditions. Axial, coronal, and sagittal sections were evaluated to assess the prevalence of CS, the direction and diameter of the canal, its relation with the impacted canine, and its distance from the alveolar crest. Further, possible correlations with patient gender and age were analyzed.ResultsThe CS could be detected bilaterally in all the evaluated tomography images. The mean canal diameter was significantly larger in males than in females (P=.001). The CS ran significantly closer to the impacted canine when the canal was located horizontally (P=.03). Variations of the canal, such as accessory canals, were identified in 6 patients.ConclusionCS is an anatomical entity that may resemble periapical lesions and other anatomical structures. Evaluation with CBCT prior to surgical procedures in the anterior maxilla will help to prevent overlooking such anatomical structures and to decrease possible surgical complications.

Bu kanal ya da kanallar nazopalatin (insiziv) sinir ve nazopalatin arterin terminal dalının yanı sıra fibröz bağ dokusu, yağ dokusu ve küçük tükürük bezlerini içerir. Ayrıca NPK içerisinde kemik septumları da görülebilir. Son dönemlerde fonksiyonel ve estetik sebeplerden dolayı anterior bölgeye yerleştirilen implantların sayısında artış yaşanmaktadır. Dolayısıyla, cerrahi işlemlerdeki komplikasyonları önlemek amacıyla bu bölgedeki anatomik oluşumlar ve varyasyonları önem arz etmektedir. Bu derlemede, NPK'nın gelişim aşamaları, anatomisi, morfometrik özellikleri ile kistleri detaylı olarak incelenecektir. ANAHTAR KELİMELER Anatomik varyasyon, arter, nasopalatin kanal, sinir ABSTRACT Nasopalatine canal and its clinical importance: A reviewThe nasopalatinal canal (NPC) is located in the anterior part of the hard palate and connects the nasal cavity and the oral cavity. These channels include the nasopalatin (insiziv) nerve and the terminal branch of the nasopalatine artery, as well as fibrous connective tissue, fat tissue and small salivary glands. Bone septum can also be seen in NPC. Recently, the number of implants placed in the anterior region has increased due to functional and aesthetic reasons. Therefore, anatomical formations and variations in this region are important to prevent complications in surgical procedures. In this review, the developmental stages, anatomy, morphometric features and cysts of the NPC will be examined in detail.

“…Aunque la estructura anatómica neurovascular más conocida en la región anterior del maxilar superior es el conducto nasopalatino, que podemos identificar en radiografías bidimensionales junto a su foramen incisivo (1), en esta zona también debemos considerar otros conductos óseos que pueden contener elementos neurovasculares y que son difícilmente identificables en radiografías bidimensionales (2,3). Estos conductos accesorios son relativamente frecuentes y de relevancia clínica, dado que las estructuras neurovasculares que albergan pueden ser de calibre significativo (2,4). Dichos conductos han recibido varias denominaciones: conducto lateral incisivo, variaciones neurovasculares en el paladar anterior y canales accesorios o canales adicionales.…”

Introducción: En la región anterosuperior, además del conducto nasopalatino, podemos encontrar otros conductos neurovasculares que pueden ser evaluados por medio de tomografía computarizada de haz cónico. El propósito de este estudio es determinar la presencia, número, diámetro, dirección y emergencia de conductos accesorios en áreas dentadas y desdentadas en la población de Cochabamba. Materiales y métodos: Se evaluaron 300 tomografías computarizadas de haz cónico de pacientes que acudieron al centro radiográfico CERPAX, mayores a 15 años y con un tamaño de voxel mínimode 0,2 mm. Resultados: Se encontró una frecuencia de 47,33% de conductos accesorios con un diámetro igual o mayor a 1 mm. Se halló a un paciente con 4 conductos accesorios. El diámetro medio de los conductos fue de 1,44 mm y el máximo de 2,80 mm. El diámetro fue mayor en zonas desdentadas. La mayor emergencia se encontró en la región de los incisivos centrales y a nivel de la tabla ósea palatina. Hubo asociación significativa entre la emergencia a nivel de las tablas óseas y el estado dental de la zona. La mayor parte de los conductos tiene dirección hacia el canalis sinuosus. Conclusiones: El diámetro mayor encontrado es el valor máximo hasta la fecha. El diámetro es mayor en áreas desdentadas que en dentadas. Es importantetomar en cuenta a los conductos accesorios de esta región antes de cualquier procedimiento quirúrgico en la zona a finde evitar una lesión en el paquete vasculonervioso.

Cone beam computed tomographic analysis of neurovascular anatomical variations other than the nasopalatine canal in the anterior maxilla in a pediatric population

Abstract: The study confirms the presence of bone channels within the anterior maxilla other than the NPC in a pediatric population. Over 22 % of the population studied had additional foramina other than the NPC in the anterior palate, between 1 and 1.7 mm wide, with variable locations.
