Perilymphatic Fistula Following a Closed Head Injury
ثبت نشده
چکیده
PLF is a condition where there is an abnormal communication between the fluid-filled perilymphatic space of the inner ear and the air-filled space of the middle ear. This fistula is a passage for the flow of perilymph fluid into the middle ear compartment. PLF is broadly classified into two main categories of congenital or acquired. Main acquired etiologies include traumatic, erosive, iatrogenic and idiopathic [1]. Moreover, traumatic tears in the oval or round windows remain a major cause.
