Background: Nasotracheal intubation (NTI) is performed after administering general anesthesia, where an endotracheal tube is inserted through the nose into the trachea, allowing delivery of anesthetic gases while providing clear access to the mouth and throat. It's commonly used in dental, oropharyngeal, and maxillofacial surgeries. Video laryngoscopy, including the Glidescope, provides an indirect view of the glottis via a camera, improving success in difficult airways.

Aims of the study: To determine the effect of using video laryngoscope for nasotracheal intubation regarding improvement in: ease of intubation, time of intubation and lowering postoperative moderate to severe sore throat.

Methods: The study was a parallel group, randomized controlled trial conducted at Al Sadr Medical City from 1st of September 2023 to 1st of September 2024, involving 50 patients undergoing elective oral and maxillofacial surgery. Patients were randomly divided into two groups: intubation with direct laryngoscopy or McGRATH MAC Video Laryngoscope. Data collected included demographics, BMI, intubation time, ease, attempts, and postoperative sore throat severity.

Results: The study compared 50 patients undergoing nasotracheal intubation using either a direct laryngoscope (DL) or video laryngoscope (VL). Both groups were similar in socio-demographic and clinical characteristics (p > 0.05). Significant findings included longer intubation time with VL (31.16 ± 3.9 vs. 16.36 ± 3.14 minutes, p=0.001), more difficult intubations with VL (40% vs. 0%, p=0.001), the intubation was successful from the first attempt among all patients in the first group vs 76% of patients in the second group (p=0.009).
