Correlation of the inclination of the tentorium cerebellum and the volume of the posterior cranial fossa.

Aim To investigate the influence of the inclination and insertion of the cerebellar tentorium on the posterior cranial fossa (PCF) volume. Methods A retrospective, non-randomized study including 174 patients (117 females and 57 males) who underwent magnetic resonance imaging in the period from 31 December 2020 to 1 June 2021 under the indication (mostly headache) set by a competent ordinary. Acute or chronic intracranial events were not verified in the patients. Results The average value of the PCF volume was 138.93 cm3 and the slope of the tentorium was 44.15°. Comparing the volume of the PCF and the slope of the tentorium in males and females no significant difference was found. A correlation was found in the females age groups 18-24 and 45-54 years. Conclusion Understanding dimensions of the posterior cranial fossa morphometry has clear implications for reducing morbidity and mortality in surgery, especially in the case of applying lateral approaches and their variations.
