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.

number of the patients with successful nasotracheal intubation and scoring difficult intubation scale
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)
Time frame: half an hour
time to intubate
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.
Time frame: 10 minutes
