Abstract:
A perilymphatic fistula (PLF) is an abnormal leakage of the perilymph from the inner ear into the middle ear. A PLF may be trauma-induced or may occur with unknown causes. PLF repair should be considered when patients present with sudden or progressive sensorineural hearing loss with positional nystagmus. Although the leakage of perilymph is not always found during the exploration surgery, both hearing loss and dizziness tend to improve immediately after PLF repair. However, about 24% of patients who underwent PLF repair reportedly have experienced recurrent vestibular symptoms, suggesting the possibility of PLF recurrence or other vertigo causes. In this PLF patient, dizziness completely subsided after the PLF repair. However, several months later, the disabling paroxysmal positional vertigo developed, which was diagnosed as benign paroxysmal positional vertigo. Reported herein, with a review of the relevant literature, is a case of paroxysmal positional vertigo several months after PLF repair, where successful vertigo subsidence was finally achieved.
