Mandibuler retromolar kanal ve foramenin konik ışınlı bilgisayarlı tomografi ile değerlendirilmesi

Öz

Amaç: Bu çalışmanın amacı, bir Türk popülasyonunda konik-ışınlı bilgisayarlı tomografi (KIBT) kullanılarak retromolar kanal (RMK) ve retromolar foramen (RMF) oluşumunun değerlendirilmesidir.

Materyal ve Metod: Çalışmaya 350 hastanın (177 erkek, 173 kadın, ortalama yaş 31.9, 18-70 yıl arasında değişen) KIBT görüntüleri dahil edildi. RMK, mandibular kanaldan bağımsız olarak ramusta bulunan veya retromolar fossa üzerinde bir foramen ile devamlılık gösteren ve mandibular kanaldan kaynak alnan bir aksesuar kanal olarak tanımlandı. RMK'lar cinsiyet ve taraf dikkate alınarak analiz edildi. İstatistiksel değerlendirmede, bağımsız örnekleri analiz etmek için ki-kare testi kullanıldı. P <0.05 istatistiksel olarak anlamlı kabul edildi.

Bulgular: RMK, hastaların% 11.42'sinde tespit edildi. Bunlardan 11'inde (% 3,14) bilateral, 29'unda unilateral RMK (% 8,28) saptandı. Sağ ve sol taraflar arasında veya cinsiyetler arasında anlamlı bir istatistiksel fark bulunmadı (P> 0.05).

Sonuç: RMK, oral cerrahi uygulayıcılarının bilmesi gereken anatomik bir varyasyondur. Hasarlandığında hipoesteziye ve hastanın gereksiz rahatsızlığına neden olabilir. KIBT, retromolar foramen ve kanalın anatomik özelliklerini ortaya çıkarmak için yararlı bir araçtır.

Evaluation of the retromolar canal and foramina of the mandible with cone-beam computed tomography

Abstract

Background: The goal of this study was to investigate the occurrence of retromolar canal (RMC) and retromolar foramen (RMF) using cone-beam computed tomography (CBCT) in a Turkish subpopulation.

Methods: This study included high-resolution CBCT images from 177 male and 173 female, totally 350, with average age of 31.9 years (18 to 70 years). The RMC was defined as an independent accessory canal or arising from the mandibular canal continuous with a foramen on the retromolar fossa. The RMCs were analyzed by considering sex and side. Independet samples statistically analyzed with chi-square test. P<0.05 was considered statistically significant.

Results: The RMC was detected in 11.42% of patients. Of these, 11 patients (3.14%) had  bilateral RMC, while 29 patients (8.28%) had a unilateral RMC. There were no differences between left and right sides or between genders (P>0.05).

Conclusions: RMC is an anatomic variation that performers of oral surgery should be aware of. It could potentially cause hypoesthesia and unnecessary discomfort of patient when injured. CBCT is a useful device to reveal anatomic features of the retromolar foramen and canal.
