Résumé

ImportanceSurgical difficulty quantification is crucial to develop educational curricula for progressive training. This need remains unmet in endoscopic endonasal surgery (EES).ObjectiveThe objective was to classify the basic skills and procedures of EES according to the perceived difficulty by experts to build a progressive curriculum.DesignThree-round modified Delphi study.SettingE-survey with an international panel of EES experts.ParticipantsFifty-nine international experts were selected on their publications in the field of EES and medical education and invited to participate. Fifteen experts from 5 countries completed the survey.InterventionA 3-round modified Delphi study was conducted.Main Outcome MeasuresIn round#1, basic skills and EES procedures were identified and the basic skills required for these procedures were listed. In round#2, the expert panel ranked the difficulty of basic skills, and in round#3, the difficulty of the EES procedures. The basic skills were grouped into 3 categories of increasing difficulty, and the subsequently-calculated difficulty of each EES procedure was compared with the experts' score. Consensus was defined at ≥80% agreement.ResultsTwenty-three basic skills and 26 EES procedures were identified. Basic skills were ranked in 3 groups of increasing difficulty, from easiest (navigation with a 0° telescope) to most difficult (suturing in the nasal cavity), with ≥80% agreement. The least difficult procedure ranked was polypectomy, whereas the most difficult was Vidian neurectomy. The correlation between the expert score and the calculated score reached an R of .75, reflecting the cumulative effect of these required competencies on procedure difficulty.ConclusionsConsensus was achieved to rank basic skills and EES procedure according to the perceived difficulty by experts.RelevanceThis study provides a basis for quantifying surgical difficulty in EES and pave the way for developing a progressive educational curriculum.
