Prevention of recurrence post leptomeningeal cyst repair.

Leptomeningeal cysts, which are cystic collections filled with cerebrospinal fluid, are rare complications following pediatric head trauma and surgical correction of craniosynostosis. These cysts develop due to cerebrospinal fluid pulsations and brain growth that cause expansion of the dural tears. Although primary repair of the dural defect is the definitive treatment, the risk of cyst recurrence remains.

Innovative real CSF leak simulation model for rhinology training: human cadaveric design.

Objective: To study the feasibility of designing a human cadaveric simulation model of real CSF leak for rhinology training.

Method: The laboratory investigation took place at the surgical academic center of Prince Sultan Military Medical City between 2016 and 2017. Five heads of human cadaveric specimens were cannulated into the intradural space through two frontal bone holes.
