Fish bones and other foreign bodies

In this prospective study the types of foreign body ingested, sites of impaction, radiographical findings, management and outcome in 81 patients were recorded. We have demonstrated that foreign bodies can be conveniently divided into 'fish bones' and 'others', in terms of their sites of impaction (P < 0.0001), the age groups affected, whether dentures were worn or not (P < 0.02) and their respective management (P < 0.001). Statistical analysis supporting these observations has not been previously reported.
