A Silky terrier weighing 4.7 kg was presented with an airway foreign body after having aspirated a fragment of an orotracheal tube that was identified on radiological examination. Due to the small size of the patient, flexible endoscopy could not be performed through the lumen of a tracheal tube. Following IV induction of general anesthesia, the airway was instrumented with a laryngeal mask airway that was attached via a three-way connector to an anesthesia breathing circuit. A flexible endoscope was passed through the free port of the connector. That arrangement allowed for the passage of an endoscope through the lumen of the laryngeal mask airway and into the trachea without interrupting the continuous supply of O2 and sevoflurane.
