Arm && Interventions

Group	Intervention	Description
conventional laryngoscopy	conventional laryngoscopy	experimental conventional laryngoscopy group: laryngoscope is used to assist for nasotracheal intubation.
video-stylet	video-stylet	experimental video-stylet group:video-stylet is used to guide nasotracheal tube into trachea

Primary Outcome Measures

Name	Time	Method
number of the patients with successful nasotracheal intubation and scoring difficult intubation scale	half an hour	Nasotracheal intubation assisted by a video-stylet may be performed in patients undergoing oro-maxillo-facial surgery 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 Outcome Measures

Name	Time	Method
time to intubate	10 minutes	time of Intubating the nasotracheal tube (NT) from selected nostril to trachea is continuously calculated but separately into two parts. part one: from termination of mask ventilation and mask removed from face, to the NT tip on the nasopharynx. part two: advancing NT from nasopharynx, through vocal cord into trachea, to present of 3 end tidal carbon dioxide waveforms.
