Study Overview
Brief Summary
Nasotracheal intubation (NTI) is usually required in patients undergoing maxillofacial surgery. Though video-scopes have been demonstrated to well perform in oral endotracheal intubation, limited information presents in NTI. The aim of the study is to compare the efficacy of video-scopes in NTI and compared with the traditional direct laryngoscope.

Outcomes
Primary Outcomes
number of the patients with successful nasotracheal intubation and scoring difficult intubation scale
Time Frame: half an hour
Nasotracheal intubation assisted by a video-stylet may be performed in patients following induction of anesthesia (fentanyl 2 micro-gram/kg, thiamylal 5 mg/kg, cis-atracurium 0.2 mg/kg and propofol 1 mg/kg)
Secondary Outcomes
- time to intubate(10 minutes)
