to investigate the effectiveness of techniques of either using Magill forceps or cuff inflation in facilitation of nasotracheal tube advancement into trachea
Patients who undergo oxo-maxillofacial surgery need naso-tracheal intubation to present good surgical view-field. but, sometimes, the naso-tracheal tube is unable to advance from nasopharynx, oropharynx, into trachea without assistance. Using techniques of either Magill forceps or cuff inflation is advantageous is not determined.
