Interventions

Intervention1: intubation with cuff inflation technique: after the endotracheal cuff is visualised in the oropharynx, cuff is inflated giving the tube a lift and bringing it in alignment with vocal co

Design outcomes

Primary

Measure	Time frame
To compare the total intubation time (TIT) between the cuff inflation technique and the non cuff inflated technique under video laryngoscopy as a measure of procedural ease.Timepoint: T1- the total time taken to pass te he endotracheal tube from nose till it is visualised in the oropharynx t2- time taken to pass the tube from the oropharynx to the glottis between the vocal cords	—

Secondary

Measure	Time frame
1. To compare the success rate and number of attempts required for nasotracheal intubation between both groups. 2. To objectively assess and compare the intubation difficulty using the Intubation Difficulty Scale (IDS). 3. To evaluate the need for adjuncts or alternative techniques such as Magill s forceps or bougie. 4. To assess the incidence of intraoperative trauma, including nasal bleeding, mucosal injury, or cuff rupture. 5. To compare post-extubation complications, such as sore throat, hoarseness, and pain on swallowing, between both groups. Timepoint:	—
