Abstract

Aim: The greater palatine canal connects to the oral cavity through the greater palatine foramen. Preoperatively identifying the morphology of the greater palatine canal and greater palatine foramen is very important to avoid possible complications during surgery. This study aimed to evaluate the greater palatine canal and surrounding anatomical structures using computed tomography.
Material and Methods: Images from 100 patients (35 female and 65 male) who had previously undergone computed tomography for various reasons were evaluated. The study data were divided into three age groups, <20 years, 20-60 years, and >60 years. Morphological parameters measured in this study included; diameter measurement from the widest part of the canal, length of the canal, beginning diameter of the canal, the ends diameter of the canal, localization of the canal entrance with respect to the third molar tooth, distance of the canal entrance to palatine suture. The values obtained from the measurements were compared in terms of age group, gender, and side.
Results: The mean length of the canalis palatinus major was 15.19±4.38 mm. The diameter of the widest part of the canal and the end of the canal, and the distance between the canal entrance and the sutura palatina increased with age, but these increases were not statistically significant.
Conclusion: Proper administration of anesthesia through the greater palatine foramen in maxillofacial surgeries and related applications requires a detailed understanding of the anatomy of the greater palatine canal, and the results of the present study will contribute to the understanding of this anatomy.

Canalis Palatinus Major Morfometrisinin Bilgisayarlı Tomografi ile Değerlendirilmesi

Abstract

Amaç: Canalis palatinus major, foramen palatinum majus aracılığı ile ağız boşluğuna bağlanır. Canalis palatinus major ve foramen palatinum majus morfolojisinin ameliyat öncesinde belirlenmesi, ameliyat sırasında ortaya çıkabilecek olan olası komplikasyonlardan kaçınmak için oldukça önemlidir. Bu çalışmanın amacı, canalis palatinus major ve çevresindeki anatomik yapıların bilgisayarlı tomografi ile değerlendirilmesidir.
Gereç ve Yöntemler: Daha önce çeşitli nedenler ile bilgisayarlı tomografisi çekilmiş olan 100 hastanın (35 kadın ve 65 erkek) görüntüleri incelendi. Çalışma verileri <20 yaş, 20-60 yaş ve >60 yaş olmak üzere üç yaş grubuna ayrıldı. Bu çalışmada ölçülen morfolojik parametreler; kanalın en geniş kısmından çap ölçümü, kanalın uzunluğu, kanalın başlangıç çapı, kanalın uç çapı, kanal girişinin üçüncü molar dişe göre lokalizasyonu ve kanal girişinin sutura palatinaya olan uzaklığıdır. Ölçümler sonucu elde edilen değerler, yaş grubu, cinsiyet ve taraf açısından birbiriyle karşılaştırıldı.
Bulgular: Canalis palatinus majorun ortalama uzunluğu 15,19±4,38 mm idi. Kanalın en geniş yerinin çapı ile bitiş yerinin çapı ve kanal girişi ile sutura palatina arasındaki mesafe, yaş ile birlikte artmış olmakla birlikte bu artışlar istatistiksel olarak anlamlı değildi.
Sonuç: Maksillofasiyal cerrahilerde ve bununla ilgili olan uygulamalarda anestezinin foramen palatinum majus yolu ile uygun bir şekilde uygulanması için canalis palatinus major anatomisinin ayrıntılı bir şekilde anlaşılmış olmasını gerekmektedir ve bu çalışmanın sonuçları bu anatominin anlaşılmasına katkı sunacaktır.
