Direct laryngoscopy is routinely performed by both anesthesiologists and otolaryngologists and is commonly associated with dental injury, tongue paresthesia, and/or bleeding gums. However, despite its routine nature, more serious complications, such as airway injury, esophageal injury, or bradycardia due to the stimulation of the vagal reflex, can occur. 1 In extreme situations, it can present as asystole. Asystole, especially intraoperatively, is cardiogenic until proven otherwise. Described herein is a case of direct laryngoscopy

The manipulations required for airway management in anesthesia may cause a variety of different types of trauma in the mouth and pharynx, including lacerations, contusions, and dental injury. 1 In some patients, the forces applied during direct laryngoscopy, or the continual pressure exerted on the mucosa in the floor of the mouth by an endotracheal tube (ETT), may lead to unappreciated mucosal trauma and erosions. Occasionally, these lesions can lead to bony injury and even to osteonecrosis. 2 Torus mandibularis is a benign, generally

Nasotracheal intubation is a common method for securing an airway during surgical procedures involving the orofacial complex. The placement of a nasotracheal tube is often more challenging than oral intubation, especially for providers who are in training or those with less experience, even for patients with normal airway anatomy. Video laryngoscopy is an adjunctive technique in anesthesia that utilizes a camera at the tip of the laryngoscope blade, which provides an indirect view of the glottis and surrounding structures during intubation

The incidence of previously undiagnosed laryngeal masses discovered during laryngoscopy reportedly ranges from 1 in 1250 to 1 in 4200. 1 Laryngeal masses are not easily discovered on routine preoperative examination since they are usually asymptomatic. However, displacement of a mass into the airway due to intubation maneuvers can have catastrophic consequences in an anesthetized patient. Previous reports have established the usefulness of video laryngoscopy while intubating patients with laryngeal masses. 2 , 3 In this case, a laryngeal

The estimated incidence of epiglottic cysts identified during laryngoscopy was historically reported to be 4 in 5000 laryngoscopies (0.08%), whereas large epiglottic cysts were reportedly rarer (0.02%). 1 , 2 Obtaining an accurate assessment of the incidence is difficult as smaller epiglottic cysts may be remain unidentified or unreported. Epiglottic cysts account for approximately 0.025 to 0.1% of all benign laryngeal masses 3 and are often reported in infants and in adults in their 50s. These soft tissue masses can cause obstruction of
