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

Area of Science:

• Neurosurgery
• Otolaryngology
• Medical Simulation

Background:

• Cerebrospinal fluid (CSF) leaks pose significant challenges in rhinology.
• Effective training for skull base reconstruction is crucial for patient safety.

Purpose of the Study:

• To assess the feasibility of a human cadaveric simulation model for CSF leaks.
• To evaluate its utility in rhinology surgical training.

Main Methods:

• A laboratory investigation using five human cadaveric specimens.
• Intracranial injection of fluorescein-dyed fluid followed by iatrogenic skull base defects.
• Endoscopic endonasal repair and assessment of watertight closure.

Main Results:

• The model successfully simulated CSF leaks at multiple skull base locations (cribriform plate, fovea ethmoidalis, planum sphenoidale, sellar, and clival regions).
• All iatrogenic defects were amenable to watertight closure using various reconstruction techniques.

Conclusions:

• The developed cadaveric model effectively simulates real CSF leaks.
• It offers a valuable platform for rhinology trainees to acquire and refine skull base reconstruction skills.
• Further evaluation is recommended to establish its role as a training tool.
