Forei gn bodies are one of the most common ENT (Ear, Nose and Throat) urgencies. Serious complications may occur, like tympanic perforations and bronchoaspiration, but they are uncommon. Aim: To analyze a 1356 foreign body series and establish causes for the complications, looking at prevention. Materials and methods: 1356 patients with ear, nose and throat foreign bodies from the ENT Department of Souza Aguiar Hospital, in Rio de Janeiro, between 1992 and 2000, were analyzed in a retrospective study for parameters like age, gender, type and localization of the foreign body, time span between introduction and removal of the foreign body and complications. Results: The most common foreign bodies were beans and the most frequent age was between 1 and 4 years old. Ear foreign bodies were the most common, followed by nasal foreign bodies. Complications were statistically related to time, child's age and practical experience of the physician. Conclusion: Most of the situations related to ENT foreign bodies are avoidable. Improvements in Public Health Assistance and otolaryngologists' training are essential to avoid serious complications.
