Amaç: Hemifasiyal Spazm (HS) yaşam kalitesini etkileyen bir durumdur. Yüzün tek taraflı istemsiz, tonik veya klonik kasılmaları olarak tanımlanır. Mikrovasküler dekompresyon (MVD) yedinci sinir üzerine vasküler bası var ise birinci seçenek tedavisidir. Son zamanlarda endoskop kullanılarak yapılmaya başlanmıştır. Çalışmamızdaki amaç full endoskopik MVD cerrahisi için gerekli becerilerin gelişimi için kadavra koyun başı modeli geliştirilmesidir.

Gereç ve Yöntem: Çalışmada kullanılan materyal, yerel bir kasaptan temin edilen 5 adet taze koyun başıdır. Cerrahi adımlar, koyun kafalarının posterioru cerraha bakacak şekilde konumlandırılması, oksipital kondilin 1 cm üzerinden kraniyektomi yapılması, dura materin açılması, serebellar dokunun tanımlanması ve mediale çekilmesi, endoskop kullanılarak sisternlerin ve ardından kraniyal sinirlerin tanımlanması ve mikrovasküler dekompresyonun simüle edilmesinden oluşmaktadır.

Bulgular: Koyun kafataslarıyla full endoskopik MVD cerrahisi simüle edilmiştir.

Sonuç: Endoskopik MVD cerrahisine aşina olmaya olanak sağlaması açısından kadavra koyun başı modellerinin kullanılması endoskopik cerrahi pratiği ve egitimi için faydalı olabilir.

Aim: Hemifacial Spasm (HFS) is a condition that significantly impacts quality of life. It is characterized by involuntary, tonic or clonic contractions on one side of the face. Microvascular decompression (MVD) is the primary treatment option when vascular compression on the seventh cranial nerve is present. Recently, endoscopic techniques have been introduced for this procedure. The aim of our study is to develop a sheep head cadaver model to facilitate the acquisition of necessary skills for fully endoscopic MVD surgery.

Material and Methods: The material used in the study was 5 fresh sheep heads, obtained from a local butcher. The surgical steps consist of positioning the sheep's heads with its posterior facing the surgeon, performing a craniectomy 1 cm above the occipital condyle, opening the dura mater, identifying the cerebellar tissue and retracting it medially, identifying the cisterns and then the cranial nerves using an endoscope, and simulating microvascular decompression.

Results: Fully endoscopic MVD surgery was successfully simulated using the sheep skulls.

Conclusion: The use of sheep head cadaver models may be beneficial for endoscopic surgical training and practice, as they provide a practical means for familiarization with endoscopic MVD techniques.
