A 38-year-old woman with a history of oral submucous fibrosis (OSMF) and trismus (mouth opening 1.5 cm) is scheduled for elective thyroid surgery. Awake fiberoptic intubation is planned. After topicalization with 4% lidocaine spray and 10% lidocaine gel, you attempt nasal fiberoptic intubation but encounter severe epistaxis from the right nostril, obscuring the view. The patient is maintaining spontaneous ventilation and oxygen saturation is 96% on room air. What is the most appropriate next step?
