A Novel International Endoscopic Sphenoid Surgery Classification (IESSC): A Delphi Consensus.

Area of Science:

• Otolaryngology
• Neurosurgery
• Surgical Innovation

Background:

• Endoscopic sinus and skull base surgery advancements necessitate standardized terminology for sphenoid sinus procedures.
• Existing classification systems for other sinuses highlight the lack of a standardized system for endoscopic sphenoid sinus surgery.
• A common language is crucial for standardizing procedure descriptions among surgeons.

Purpose of the Study:

• To develop a novel classification system for endoscopic sphenoid sinus surgery.
• To establish standardized terminology for describing sphenoid sinus surgical procedures.
• To facilitate clear communication and discussion among surgeons performing these procedures.

Main Methods:

• A Delphi procedure was employed to achieve consensus on the classification system.
• Sixteen rhinology experts from diverse international locations participated in the consensus-building process.
• Four rounds of the Delphi procedure were conducted to finalize the classification stages.

Main Results:

• Consensus was reached on all stages of the endoscopic sphenoid surgery classification system.
• The average agreement percentage increased from 70.83% to 87.68% across the four Delphi rounds.
• The developed classification includes stages for presphenoid surgery, partial/complete/transpterygoid sphenoidotomy, Rostral sphenoidectomy, and extended sphenoid drill-out.

Conclusions:

• A novel classification system for endoscopic sphenoid surgery has been successfully developed.
• This system provides a standardized framework for describing various sphenoid sinus procedures.
• The classification enhances opportunities for discussion and communication among surgeons in the field.
