초록

Postoperative vertigo after tympanomastoidectomy can be attributed to several causes such as inner ear damage
due to excessive ossicle handling, labyrinthitis, BPPV resulting from vibration of drilling, iatrogenic lateral
semicircular canal damage, and perilymphtic fistula. Differential diagnosis is critical for the proper management
and prognosis of accompanied sensorineural hearing loss, but it may be difficult in some cases. Especially it is
quite difficult to distinguish between the serous and suppurative labyrinthitis. In this article we present a case with
simultaneous serous labyrinthitis and BPPV. The patient developed whirling vertigo and hearing loss on the 5th
day after tympanomastoidectomy. After conservative treatment with steroid and antibiotics, his hearing recovered
to preoperative level. We retrospectively reviewed the pitfalls to make a correct diagnosis in this patient and the
serial change in nystagmus during the treatment period. The usefullness of the rotation chair test to predict the
prognosis of sensorineural hearing loss in labyrinthitis was also discussed.
