Brief Summary:
Investigators hypothesized that the surgical condition will be improved with the use of sugammadex in patients undergoing laryngeal microsurgery. Investigators will compare the effect of sugammadex and neostigmine on the surgical condition during laryngeal microsurgery.

Arm Intervention/treatment
Experimental: Neostigmine arm
Neostigmine arm
Drug: Neostigmine
In neostigmine group, neostigmine 50 ㎍/kg will be administered intravenously with glycopyrrolate 10 ㎍/kg when the T2 response appears on TOF stimuli.

Active Comparator: Sugammadex arm
Sugammadex arm
Drug: Sugammadex
In sugammadex group, sugammadex (Bridion, Merck Shart and Dohme (MSD), Oss, the Netherlands) will be administered intravenously in different doses according to the degree of muscle relaxation. Sugammadex 8 mg/kg will be administered if there is no response on post-tetanic count (PTC) stimulus. Sugammadex 4 mg/kg will be administered if PTC is more than 1 or 2. Sugammadex 2 mg/kg will be administered if T2 response appears on train-of-four (TOF) stimulus.

Primary Outcome Measures :
  1. surgical condition [ Time Frame: up to 1 hour after the end of surgery ]
    Primary outcome is the proportion of patients who have clinically acceptable surgical condition. The surgeon will evaluate the surgical condition as a surgical rating scale during surgery (extremely poor condition, poor condition, acceptable condition, good condition, optimal condition).
