Division pattern of the hypoglossal canal in human fetuses

Abstract

Aim: The aim of this study was to determine the presence and ratio of septum or double hypoglossal canals in human fetuses. Method: In the inventory of the Department of Anatomy, Faculty of Medicine, twenty-five fetuses (14 males and 11 females) with a mean age of 23.36 ± 2.63 weeks of gestation were included in the study. Results: Double hypoglossal canal was detected in 9 (36%) of the 25 fetuses investigated. The double hypoglossal presence was bilateral in 2 (%8) fetuses, while 7 (%28) fetuses were unilateral. The presence of double hypoglossal canal incidence was 12% on the right and 16% on the left. There was no relationship between the presence of a septum and gestational age, gender or side. Conclusion: The division of the hypoglossal canal with a bony septum is of great importance for neurosurgeons and radiologists, especially for posterior cranial fossa operations such as hypoglossal canal schwannomas. Additionally, the data presented in this study may be valuable for anatomists and anthropologists in understanding the development of the skull base.

Abstract

Amaç: Bu çalışmanın amacı, insan fetüslerinde septum veya çift hipoglossal kanal insidansını tespit etmektir. Yöntem: Tıp Fakültesi Anatomi Anabilim Dalı envanterinde bulunan ortalama 23.36±2.63 haftalık 25 fetüs (14 erkek, 11 kız) çalışmaya dahil edildi. Bulgular: Fetüslerin 9’unda (%36) septum vardı. Fetüslerin 2’sinde (%8) bilateral, 3’ünde (%12) sağ ve 4’ünde (%16) sol tarafta çift hipoglossal kanal tespit edildi. Gestasyonal yaş, cinsiyet ve taraflar ile septum varlığı arasında bir ilişki görülmedi. Sonuç: Hipoglossal kanalın bölümlenme paterni özellikle hipoglossal kanal schwannoma’ları gibi posterior kraniyal fossa operasyonları açısından önem taşıdığından nörocerrahlar ve radyololar için büyük önem taşımaktadır. Ayrıca çalışmamızdaki veriler, kafa tabanının gelişiminin anlaşılması açısından anatomistler ve antropologlar için kıymetli olabilir.
