We report a case of subperiosteal orbital abscess and discuss the effectiveness of surgery. The patient was a 10-year-old boy who complained of a headache and swelling of the left eyelid. No eye movement disorders or visual field loss were recognized. Conservative treatment was performed, but the patient developed diplopia and exophthalmos without any improvement in his symptoms. Endoscopic paranasal sinus surgery was performed under general anesthesia, break orbital medial wall and drained out from the orbital abscess. The patient’s symptoms promptly improved after the operation.
