====== Position for supracerebellar transtentorial approach ======

The [[sitting position]] for [[supracerebellar transtentorial approach]] allows [[gravity]] to work in the surgeon’s favor by facilitating cerebellar retraction and reducing venous bleeding and pooling in the operative field. 
As an alternative, the [[approach]] can be performed in the [[Park Bench Position]] or [[Concorde position]].

Since [[supracerebellar transtentorial approach]] was introduced by Voigt and Yaşargil
((Voigt K, Yaşargil MG: Cerebral cavernous haemangiomas or cavernomas. Incidence, pathology, localization, diagnosis, clinical features and treatment. Review of the literature and report of an unusual case. Neurochirurgia (Stuttg) 19:59– 68, 1976))
, many researchers used SCTT in different positions. In particular, the [[sitting position]] was the most preferred as it allows the cerebellum to fall away from the [[tentorium]]. However, this [[position]] has [[disadvantage]]s such as [[venous air embolism]] (VAE), [[Paradoxical Embolism]], and some non-ergonomic conditions during surgery. 

Kocaoglu and Acar reported two cases with tumors affecting the middle and posterior medial temporal regions. Both patients underwent surgeries in the [[prone position]] using the SCTT approach. There were no procedure-related complications. Histopathological results were as follows: [[psammomatous meningioma]] in the first case; adenocarcinoma metastases in the second case. Thus, in this study, the efficacy, feasibility, and safety of accessing the MTR using the SCTT approach in the prone position were demonstrated
