This is a single-blinded randomized controlled trial to compare the outcomes of early closed suction drain removal versus output volume-based drain removal after selective lateral neck dissections (SLND). The main hypothesis of the study is that the early drain removal of closed suction drains on the first postoperative day is safe compared to the current practice of output volume-based drain removal when output is less than 30ml/24hr or 15ml/12hr. This study will also evaluate the hypotheses that output volume-based drain removal of surgical drains increases inpatient length of stay and decreases the average patient satisfaction score on the measurement of quality of recovery (QoR-40).
