外耳道異物83症例の検討

抄録

Between November 1985 and June 1997, 83 cases of foreign bodies in the external auditory canal were treated in our department. They represented 0.352% of the total number of outpatients during the same period. Forty-six of the cases were children under 10 years of age, which accounted for 55.4% of all cases. In total, there were 49 male patients and 34 female patients, including 46 right side cases, 36 left side cases and only one case affected on both sides. Biotic foreign bodies were seen in 20 cases mostly adults, with peak occurrence in July and August. Among nonbiotic foreign bodies, mineral foreign bodies were most numerous, and in 19 cases toy-globes were removed. In 50 of the cases mostly children foreign bodies had been inserted during play. A total of 27 cases were asymptomatic. At the time of removal, intravenous anesthesia with ketamine hydrochloride was very effective in keeping patients, especially children, quiet and still.
