Abstract
Perilymphatic fistula, which is an abnormal connection between the labyrinth and the structures surrounding it, presents clinically with fluctuating hearing loss, vertigo, and tinnitus. Patients may have Hennebert sign and a positive fistula test. Perilymphatic fistula is a diagnostic challenge; audiometry and electronystagmography can be beneficial to help in the diagnosis. In some instances, the middle ear has to be explored to confirm the diagnosis. Bed rest, head elevation, and avoiding straining may be the only things needed to treat this condition. However, if conservative measures fail, then surgery may be necessary. This chapter will talk in more detail regarding this condition in terms of the clinical manifestation, diagnostic tools needed, possible etiology, and management options.
