Nazopalatin Kanal Morfolojisinin Dentisyona Göre Değişiminin Konik Işınlı Bilgisayarlı Tomografi ile Retrospektif Olarak Değerlendirilmesi

Abstract

Amaç Nazopalatin kanal maksiller anterior bölgedeki önemli anatomik yapılardan biridir. Bu çalışmanın amacı nazopalatin kanal (NPK) morfolojisinin dentisyon durumuna göre değişimini konik ışınlı bilgisayarlı tomografi (KIBT) ile incelemektir. Gereç ve Yöntemler: Toplam 100 hastaya ait KIBT görüntüleri retrospektif olarak taranmıştır. KIBT görüntüleri anterior maksillanın dentisyonuna göre iki gruba ayrılmıştır; maksiller anterior bölgesi dişsiz olan 50 hasta ve diş kaybı olmayan 50 hasta. Hastaların yaş, cinsiyet ve dentisyon durumları kaydedildikten sonra sagittal kesit üzerinde NPK uzunluğu, insiziv foramen (İF) çapı, stenson foramina (SF) çapı, NPK ile palatal düzlem arasındaki NPK açısı ölçülmüştür. Bulgular: Dentisyonun NPK açısı, NPK uzunluğu, SF ve IF çapları ile ilişkisi incelendiğinde değişkenler arasında istatistiksel olarak anlamlı bir farklılık bulunamamıştır (p>0,05). Değişkenler yaşa ve cinsiyete göre değerlendirildiğinde NPK boyu ve NPK açısı erkek cinsiyette anlamlı oranda yüksek bulunurken (p<0,05), insisiv foramen çapının yaş ile arttığı ve bunun istatistiksel olarak anlamlı olduğu görülmüştür (p<0,05). Sonuç: NPK hem morfolojisi hem de boyutları açısından önemli anatomik farklılıklar gösterebilir. Dentoalveolar cerrahi sırasında olası komplikasyonları önlemek için dikkatli bir preoperatif değerlendirme gereklidir.

Retrospective Evaluation of Changes in Nasopalatine Canal Morphology According to Dentition with Cone Beam Computed Tomography

Abstract

Aim: Nasopalatine canal is one of the important anatomical structures in the anterior maxillary region. The aim of this study was to investigate the changes in nasopalatine canal (NPC) morphology according to dentition status using cone beam computed tomography (CBCT). Material and Methods: CBCT images of a total of 100 patients were analyzed retrospectively. CBCT images were divided into two groups according to the dentition of the anterior maxilla: 50 patients with edentulous anterior maxillary region and 50 patients without tooth loss. After recording age, gender and dentition status of the patients, NPC length, incisive foramen (IF) diameter, stenon foramina (SF) diameter, NPC angle between NPC and palatal plane were measured on the sagittal plane. Results: When relationship between dentition and NPC angle, NPC length, SF and IF diameters were analyzed, no statistically significant difference was found between the variables (p>0.05). When the variables were evaluated according to age and gender, NPC length and NPC angle were found to be significantly higher in the male gender (p<0.05), while the diameter of the incisive foramen increased with age, and this was statistically significant (p<0.05). Conclusion: NPC can show significant anatomical variations in both its morphology and dimensions. A careful preoperative evaluation is necessary to avoid possible complications during dentoalveolar surgery.
