In 15 years period, 137 children with foreign bodies of inferior respiratory tracts were admitted in the otorhinolaryngology and head and neck department of the University of Dakar. For 48 of them, generally late admitted, a tracheostomy was performed. Male children were most affected. About 81% of the removed foreign bodies were organic, dominated by peanuts. 76% of the foreign bodies were found in the larynx. Tracheostomy had been realized before extraction of foreign body for 90% of the cases and after extraction for the others 10%. One case of death was to be deplored. This critical place of tracheostomy increases the morbidity and the mortality in relation with the inhalation of foreign body. This unusual practice of tracheostomy illustrates the arduousness of our working conditions.
