Abstract |
Though the microvascular decompression (MVD) for neurovascular conflict disorder is considered as a relatively safe procedure, various complications can happen. We report a case of pulsatile tinnitus after MVD for trigeminal neuralgia. A 37-year-old female presented ear fullness and hissing sound a month after MVD for trigeminal neuralgia. Otoscopic examination confirmed pulsatile tympanic membrane, but there was no abnormality on pure tone audiometry. Iatrogenic focal defect of mastoid bone at the craniotomy site was identified on thin sliced computed tomography (CT) scan. Observation for 5 months did not resolve the symptoms. Revisional operation to reconstruct that focal defect of mastoid bone was decided. The symptoms were resolved immediately after the surgery. |
