MDCT evaluation of nasopalatine canal morphometry and variations: An analysis of 100 patients

Abstract

NPC shows myriad potential variations that have various prevalences. It is assumed that familiarity with these variations may help decrease the incidence of complications during facial or dental surgery.

Anatomical evaluation of nasopalatine canal on cone-beam computed tomography images

“…In the present study, NPC was classified in six groups: cylindrical, hourglass-, banana-, cone-, funnel-and reverse cone-shaped. Most of the studies in the literature, together with this study, have identified cylindrical NPC as the most common type of nasopalatine canal [16][17][18]23]. Etoz and Sisman [13] have identified hourglass-shaped NCP as the most common type.…”

“…Although there are many studies indicating the pathologies related to NPC in the literature [4,5,8,9,12,14,17,18,22,23,27,29,30,31], the studies concerning the anatomy of NPC evaluated via CBCT are limited [1,11,13,16,19,21,37].…”

“…Mardinger et al [23] studied CT images of 207 cases and detected that 50.7% of NPC was cylindrical, 30.9% of them was funnel-shaped, 14.5% of them was hourglass-shaped and the lowest percentage of it was banana-shaped. Gönül et al [17] evaluated NPC in four groups on CT images of 100 cases and stated that 48% of those cases were cylindrical, 20% of them were hourglass-shaped, 20% of them were banana-shaped and 12% of them were funnel-shaped. Güncü et al [18] evaluated 417 male and 516 female cases on CT images and detected that NPC was cylindrical most frequently, followed by the cone-, hourglass-and least frequently banana-shaped.…”

Foraminas acessórias da região anterior da maxila em tomografia computadorizada de feixe cônico

“…Na Odontologia, a Tomografia Computadorizada de Feixe Cônico (TCFC) é uma modalidade de exame que pode ser utilizada para o planejamento e observação desses feixes neurovasculares (NICOLIELO et al, 2014;IKUTA et al, 2016 (MRAIWA et al, 2004;ASAUMI et al, 2010;ETOZ;SISMAN, 2014;AL-AMERY et al, 2015;LÓPEZ JORNET et al, 2015;SEKERCI;CANTEKIN;AYDINBELGE, 2015;WHITE;PHAROAH, 2015;GÖNÜL et al, 2016;NASSEH;AOUN;SOKHN, 2017). O nervo nasopalatino e a artéria esfenopalatina são os principais feixes neurovasculares que se inserem no CNP, e se ramificam por meio do forame incisivo para prover irrigação e inervação à mucosa palatina da região anterior da maxila (ASAUMI et al, 2010;WHITE;PHAROAH, 2015).…”

Além disso, o CNP também é constituído por tecido conjuntivo fibroso e glândulas salivares menores (GÖNÜL et al, 2016).
