Questionnaire and case notes of patients were used as data instruments for the study. Information retrieved were entered into SPSS version 11.0 computer soft ware and analyzed. A total of 78 consented patients with mean age of 10.6 years (SD =10.1 ± 1.0) were involved. Handedness of the patients showed 50 (64.1%) were right handed, 24 (30.8%) were left handed and 4 (5.1%) were not sure of their handedness or used both hands. In the correlation of handedness where foreign bodies were found, the right handed has more in the right ear in 41 (80.3%) and the left handed has more of the FB in the left ear 9 (33.3%). The P value was 0.0003 with a relative risk of 2.5. Grain/ seed constituted the commonest foreign body in 42.8%. About 64.1% of the foreign bodies were found in the right ear and 35.9% in the left ear. There was correlation between handedness of the patients and site where foreign bodies were found.
