Abstract:
Perilymph fistula (PLF) is defined as an abnormal communication between the middle ear cavity and perilymphatic space of the inner ear. Most cases of PLF are responsible for pressure change caused by internal trauma or external trauma. However, spontaneous PLF might occur without an obvious history of barotrauma. We report two cases of possible spontaneous PLF in the postpartum period: both cases involved progressive sensorineural hearing loss with positional dizziness. Although the leakage of perilymph was not found during exploration, both hearing loss and dizziness improved immediately after PLF repair. It is necessary to consider the possibility of PLF in patients who have sudden or progressive sensorineural hearing loss with positional nystagmus. Early surgical exploration is recommended even if the history of barotrauma is not clear.
