Nasal foreign bodies may result from the abundant availability of tiny objects in our society and a curious child exploring his or her nasal cavities. An inserted object that is not witnessed or retrieved can remain relatively asymptomatic or cause local tissue damage and potentially yield more serious consequences. An unusual case of a young child who presented for dental rehabilitation under general anesthesia is described. Immediately prior to the nasotracheal intubation, an unanticipated foreign body was detected and safely removed before any injury occurred. This case report discusses the presentation and pathophysiology of nasal foreign bodies. Moreover, applicable suggestions are provided to aid in the prevention and management of the unexpected discovery of a nasal foreign body after the induction of general anesthesia.
