We reported a case of a 42-year-old female who showed the jumbling phenomenon due to left labyrinthine dysfunction after GM local treatment for O. M. C.
This patient complained of otorrea and deafness, then we gave her CCL orally, GM and steroids locally as eardrops 7 times. A few days after this treatment she noticed the fullness of the ear, vertigo, nausea and vomiting.
This patient complained of difficulty i n walking on dim light and apparently felt oscillation movements of a fixed target when she moved her head to the affected ear side either actively or passively.
She has had a 12 to 13 year history of left chronic otitis media. Neurological examination of this patient showed left hearing loss and vestibular dysfunction.
There was on spontaneous nystagmus, but the DP (dir e ctional preponderance) to the right side was found. ETT and OKN were normal in this patient.
Usually, the jumbling phenomenon appears in cases that there is a loss of bilateral vestibular function. However, the jumbling phenomenon appeared in our case although she suffered from unilateral vestibular disorder.
