title: Repair of a malleus-handle fracture using calcium phosphate bone cement.
abstract: We report a case of a 60-year-old woman who reported a popping sound in her left ear, induced by changes in pressure, since she pulled her index finger out of her ear canal after accidentally inserting it while washing her hair. Otoscopic examination revealed a wrinkled tympanic membrane and irregular malleus handle. An isolated malleus-handle fracture resulting from barotrauma was suspected. The fracture was repaired surgically using calcium phosphate bone cement. Postoperatively, the problem disappeared and her hearing recovered. This case is the first to demonstrate the efficacy of calcium phosphate bone cement for repairing a malleus-handle fracture.
