<qa>  How long will the operative time be started?1. Operative time minutes will be started at the time of incision and ended at the time of complete hemostasis. After tonsillectomy on the first side is finished, 5-10 minutes is the lag time before tonsillectomy on the second side will be started in order to observe re-bleeding after operative time is recorded. If there is re-bleeding, the operative time will be changed and measured from the same starting time to the time of last complete hemostasis.
