Introduction: TA scope is an indirect optical video laryngoscope (VL) which provides a better glottic view without manipulating all three airway axis. Cuff inflation in nasal tube (NT) makes tube midline and good alignment with glottic opening. Aim: This study aims to evaluate the success rate of nasal intubation with cuff inflation technique through VL. Methods: A total of 50 patients posted for oral cancer surgery were included. After general anesthesia induction, NT passed up to oropharynx; with VL NT cuff inflation with 15 ml of air done in Group I and no cuff inflation in Group D. NT was advanced to vocal cords, cuff was deflated; the NT was then advanced into the trachea, and then cuff was reinflated (M0). If this failed, cuff inflation was further inflated 5 cc more (M1) or counterclockwise 180° rotation (M3) or help of Magill's forceps (M3) was used. Results: NT tip locations were midline in 88% after cuff inflation. The duration of intubation was earlier in inflated group (32 ± 18 s vs. 44 ± 20 s). Additional maneuvers such as more 5 cc air or Magill forceps were more in Group D (52% vs. 22% P = 0.25). First trail intubation success without any maneuvers was 48% in Group I and 12% Group D (P = 0.006). Counterclockwise 180° endotracheal tube rotation (M2) was useful to pass NT to VC in 32%, 48% Group I and D, respectively (P = 0.25). Air required for cuff inflation was 16.57 ± 2.65 ml in Group I. Conclusion: Cuff inflation technique has a good success rate with minimum additional assistance in video laryngoscopic nasal intubation.
