Lateral suboccipital craniotomy and occipital condyle resection are amongthe preferred methods. Surrounding neurovascular structures may be damaged during occipital condyleresection. The aim of study was to develop regression formulas that will determine the precise locationof the occipital condyle and estimate the distances to the surrounding anatomical structures, based onthe skull morphometry of the person.Material and Methods: The study was carried out on 22 condylus occipitalis (11 skulls) at HarranUniversity, Medical Faculty Anatomy Laboratory. The determined 27 parameters were measured via theImage J program on the skulls’ inferior, anterior, lateral and posterior aspect photographs. Multiple linearregression analysis was performed.Results: To determine the morphometric and topographic features of the occipital condyle, theequations have been developed such as; The occipital condyle length= -2.142 + (0.330 x P15) – (0.468x P19) – (0.748 x P20) + (0.807 x P21); Adjusted R2= 0.911, Standard Error of the Estimation= 0.938.Conclusion: Considering the difference between the minimum and the maximum values observed indescriptive statistics, the distribution between these values, the different findings in the studies in theliterature, there may be erroneous applications in the attempts to be made over the mean values. Webelieve that the formulas we have developed will be beneficial in personal-specific approaches. KW - Occipital condyle KW - Skull base KW - Lateral suboccipital craniectomy N2 - Amaç: Kraniyovertebral bileşkede uygulanacak cerrahi operasyonlarda morbidite ve mortaliteyiazaltmak için kafa tabanında yer alan anatomik yapıların ve bu yapılar arasındaki topografik ilişkininbilinmesi önemlidir. Lateral suboksipital kraniotomi ve condylus occipitalis rezeksiyonu tercih edilenyöntemler arasındadır. Condylus occipitalis rezeksiyonu sırasında etrafında yer alan nörovasküleryapılar hasar görebilir. Çalışmanın amacı, kişinin kafa iskeleti morfometrisinden yola çıkarak, condylusoccipitalis’in tam olarak yerini belirleyecek ve etrafındaki anatomik yapılara olan uzaklıkları tahminedecek regresyon formüllerini geliştirmektir.Gereç ve Yöntemler: Çalışma Harran Üniversitesi Tıp Fakültesi Anatomi Laboratuvarında bulunan 22condylus occipitalis (11 kafatası) üzerinde gerçekleştirildi. Belirlenen 27 parametre kafataslarının alt, ön,yan ve arka fotoğrafları üzerinde Image J programı ile ölçüldü. Çoklu doğrusal regresyon analizi yapıldı. Bulgular: Condylus occipitalis’in morfometrik ve topografik özelliklerini belirlemek için; Condylus occipitalis uzunluğu= -2,142 + (0,330 xP15) – (0,468 x P19) – (0,748 x P20) + (0,807 x P21) Düzeltilmiş R2= 0,911; Tahminin Standart Hatası= 0,938 şeklinde formüller geliştirilmiştir.Sonuç: Tanımlayıcı istatistik bulgularında gözlenen en küçük en büyük değer arasındaki fark ve bu değerler arasındaki dağılım ile literatürdeyer alan çalışmalardaki farklı bulgular dikkate alındığında ortalama değerler üzerinden yapılacak girişimlerde hatalı uygulamalar olabilir.Geliştirmiş olduğumuz formüllerin kişiye özgü yaklaşımlarda fayda sağlayacağı kanaatindeyiz.
