An instrumental improvement for endoscopic laryngeal microsurgery

Area of Science:

• Otolaryngology
• Surgical Instrumentation
• Microsurgery

Background:

• Endolaryngeal microsurgery requires high precision for delicate procedures.
• Current instrumentation may limit fine motor control during surgery.
• Improving instrument stability and precision is crucial for patient outcomes.

Purpose of the Study:

• To evaluate the impact of a novel steel wire-grid on operative precision in endolaryngeal microsurgery.
• To assess the feasibility of simultaneous bimanual instrument manipulation with the device.
• To determine if the wire-grid affects visualization during microscopic examination.

Main Methods:

• A steel wire-grid was designed and inserted into the lumen of a standard laryngoscope.
• The device was tested during simulated endolaryngeal microsurgical procedures.
• Precision of instrument manipulation and visualization quality were assessed.

Main Results:

• The steel wire-grid insertion resulted in a 3:1 precision gain for operative manipulation.
• Simultaneous use of two instruments with enhanced precision was demonstrated.
• No visual impairment was reported when using the microscope focused on the glottis.

Conclusions:

• The steel wire-grid is an effective tool for enhancing precision in endolaryngeal microsurgery.
• This innovation facilitates improved bimanual instrument control.
• The device offers a promising advancement for laryngeal surgical procedures.
