    Introduction Accurate scheduling of OR-times is essential for maximum utilisation of ORs. At the same time, compliance with working hour regulations has to be assured. In the daily clinical life this organizational challenge often results into conflicts. In order to detect sources of errors, times estimated by ENT surgeons were compared with times objectively measured in OR.

    Method In a retrospective analysis a comparison of the duration of 1809 operations (22 different types) by 31 surgeons (12 specialist (S), 19 residents (R)) of the ENT department at Mannheim university medical centre was conducted. By questionnaires estimated incision to suture, preparation and postprocessing times from 10 S and 17 R were compared to the obj. times. Both comparisons were tested for statistical significance by Mann-Whitney-U-test.

    Results Comparison of obj. times from S and R showed significant (sig.) differences for times of surgical action in 6 out of 15 types of surgery (p < 0,001). S sig. underestimated obj. postprocessing times in 2 out of 22 (p < 0,05) and R sig. underestimated it in 7 out of 15 types of surgery (p < 0,05). S overestimated incision to suture times in 7 out of 22 types of surgery (p < 0,05) and R underestimated it in 3 out of 15 types (p < 0,05). S sig. underestimated obj. preparation times in 16 out of 22 (p < 0,05) and R underestimated it in 7 out of 15 types of surgery (p=0,00).

    Discussion S underrated preparation and postprocessing times but overrated incision to suture times. R underestimated all these times without that there seems to be any obvious correlation with their personal routine for this type of surgery. Preparation and postprocessing times must be considered in the planning of OR-times and ideally determined together with the anaesthetists and OR-assistants.
