Abstract

Aim: The trigeminal nerve is the fifth cranial nerve responsible for motor, sensory and autonomic stimulation of the head and neck. The aim of this study was to examine the relationship of the trigeminal nerve and its branches in fetal cadavers.
Materials and Methods: This study was performed on 20 fetal cadavers. The height and width of the trigeminal pore were measured; the trigeminal pore type was determined. The length, width and thickness measurements of the trigeminal nerve, its branches were performed.
Results: The most common trigeminal pore type was cleft type in both male and female fetal cadavers. It was determined that the length on the left side was longer than on the right side.
Conclusion: We believe that the obtained data can provide valuable guidance planning further interventions in that region for current data on the anatomy of the region and for fetuses in the womb.

Fetal kadavralarda nervus trigeminus ve dallarının morfometrik ve klinik önemi

Abstract

Amaç: Nervus trigeminus, baş ve boyunun motor, duysal ve otonomik uyarımından sorumlu beşinci kraniyal sinirdir. Çalışmamızda, fetal kadavralarda nervus trigeminus ve dallarının çevre yapılarla olan ilişkisinin incelenmesi amaçlanmıştır.
Gereç ve Yöntem: Bu çalışma 20 fetal kadavra üzerinde gerçekleştirilmiştir. Dura mater’in oluşturduğu trigeminal açıklığın yüksekliği ve genişliği ölçüldü. Ayrıca trigeminal açıklığın tipleri belirlendi. Nervus trigeminus’un uzunluk, genişlik ve kalınlık ölçümleri, dallarının uzunlukları ölçüldü.
Bulgular: Çalışmamızda hem erkek hem de kız fetal kadavralarda en sık gözlenen trigheminal açıklık tipi yarık tip olarak tespit edildi. Sol tarafa ait nervus trigeminus uzunluğunun sağ taraftakine göre daha uzun olduğu belirlendi.
Sonuç: Çalışmadan elde edilen ölçümlerin, bölgenin anatomisine ilişkin güncel veriler sağlayacağı ve anne karnındaki fetüsler için o bölgeye yapılacak ileri müdahalelerin planlanmasında yol gösterici olabileceği kanaatindeyiz.
