Unusual Retrieval of an Ingested Metallic Foreign Body Using a Magnetic Bridle During Microlaryngoscopy: A Case Report

BACKGROUND: Ingested metallic foreign bodies in the aerodigestive tract often require prompt endoscopic or surgical retrieval, but visualization failures despite radiographic confirmation pose diagnostic and therapeutic challenges. This report describes a novel use of a magnetic-tipped bridle to localize and retrieve an unusual sieve-derived metal fragment during microlaryngoscopy. CASE PRESENTATION: A 45-year-old female presented after accidentally swallowing a small piece of metal from a kitchen sieve. Plain X-ray confirmed a 2 cm linear radiopaque foreign body in the upper aerodigestive tract. Flexible nasendoscopy and initial microlaryngoscopy failed to visualize it. During microlaryngoscopy under general anesthesia, a bridle nasogastric tube with distal magnet was advanced trans orally; magnetic attraction to the laryngeal sidewall enabled precise localization and atraumatic retrieval without complications. The patient was discharged the next day with no sequelae. CONCLUSIONS: Magnetic bridle-assisted microlaryngoscopy offers a safe, innovative adjunct for radiopaque metallic foreign bodies occult to direct visualization, avoiding rigid endoscopy or open surgery. This technique repurposes standard NG securement tools effectively in ENT practice.
