Ventrikülostomide anatomi temelli navigasyon: Nazion-Koronal sütür arası mesafe ölçümü

Öz

Amaç: Bu çalışmada nazion sınır olarak kullanılarak koronal sütür lokalizasyonu tespit edilmeye çalışılmıştır. Nazion-koronal sütür arası mesafe bildiğimiz kadarı ile Türk toplumunda ilk defa bu çalışma ile literatüre sunulmaktadır. Yöntemler: Bu çalışmada 30 kranium ve 30 frontal kemik kullanılmıştır. Her bir kafatasında mezuro yardımı ile nazal sütürden koronal sütüre olan mesafe ölçülmüştür. Sonuçlar: Nazal sütür-koronal sütür arası mesafe 12,2 cm (minimum 10,3-maksimum 13,5 cm) olarak tespit edildi. Tartışma: Nazion cilt üzerinden kolayca palpe edilebilen bir işaret noktasıdır. Naziondan 12 cm posteriorda orta hattan 3 cm lateralde yapılacak küçük bir cilt insizyonu ile drenaj noktası kolayca tespit edilebilir. Bu bilgi beyin cerrahları için her zaman kullanabilecekleri pratik bir bilgi olarak literatüre sunulmaktadır.

Anatomy-Based navigation for ventriculostomy: Nasion-coronal suture distance measurement

Abstract

Objective: In this study we aimed to determine a landmark that can be measured through the skin with nasal mid-point (bregma) to coronal suture, and additionally an average value was calculated. We report, to our knowledge, the distance between the nasion-coronal sutures is reported for the first time in Turkish population. Methods: The study included 30 craniums and 30 frontal bones. Each skull from midline nasal suture to coronal suture curved up at the distance was measured with tape measure. Results: Mean values were determined. Nasal suture between coronal suture distance average 12,2 cm (min10,3 cm, up to 13,5 cm) were detected. Conclusion: Nasal suture is an easily palpable area through the skin. A small incision is carried down through skin to bone at the spot 12 cm back from the nasion 3 cm lateral to the midline for ventricular drainage operation. This data provide practical information for neurosurgeon and is available everywhere. J Clin Exp Invest 2014; 5 (3): 368-370
