The video laryngoscope is an approved airway equipment for use in difficult airway. Borescope has been used in industrial and non-medical uses. The introduction of the borescope for the use in airway management started with the COVID-19 era by putting it over a direct laryngoscope blade to provide an economical video laryngoscope. In the current study, we investigated the use of an endotracheal tube mounted over a borescope versus a video laryngoscope in intubating suspected difficult intubation patients. After informed consent, 120 adult patients with suspected difficult intubation undergoing elective surgery were included in this study. Patients were randomized to the USB-borescope group, video laryngoscope group. Time to successful intubation was the primary endpoint. Secondary outcomes included hemodynamic change, operator satisfaction, and incidence of complications in both groups. I ntubation time was comparable between both groups (video laryngoscope = 30.63 sec, borescope = 28.35 sec, P = 0.166), yet the clarity of the view was better with the video laryngoscope compared to the borescope (P = 0.026), and incidence of fogging was less with the video laryngoscope (P = 0.015). Operator satisfaction was higher with borescope 1.56 ± 0.62 when compared to video larygoscope 1.21 ± 0.42 (P
