Modified Endoscopic Diving Technique without the Traditional Irrigation System in Endoscopic Cranial Base Surgery:...

Area of Science:

• Minimally Invasive Surgery
• Surgical Technology

Background:

• A novel modified endoscopic diving technique is presented, featuring an irrigation system distinct from existing CLEARVISION II technology.
• This technique aims to enhance visualization and control during endoscopic procedures.

Purpose of the Study:

• To introduce and evaluate a modified endoscopic diving technique for improved surgical outcomes.
• To assess the feasibility and benefits of an alternative irrigation system in endoscopic surgery.

Main Methods:

• The modified endoscopic diving technique was employed by a senior surgeon in 76 endoscopic surgical procedures between January 2016 and October 2018.
• Diving surgery was utilized in all cases to ensure complete tumor resection and removal of residual tumor tissue.

Main Results:

• The modified technique separates the optic system and irrigation source into independent tools, allowing targeted fluid delivery.
• Surgeons gain independent control over the optic system's direction, distance from the target, infusion pressure, and flow rate.
• This separation enables precise manipulation of the surgical field, independent of the endoscope's orientation.

Conclusions:

• The modified endoscopic diving technique provides surgeons with greater control over multiple parameters, enhancing surgical precision.
• It effectively bypasses compatibility issues between different endoscopic systems, offering flexibility.
• The technique's reproducibility and low instrumentation cost facilitate wider adoption and easier application of endoscopic diving surgery.
