Can Psoriasis in the Ears Lead to Tinnitus?

I've been coping with psoriasis in my ears since I was in high school. Nothing seems to help it as much as Clobetasol foam. My dermatologist took me off that and has tried more mild steroids and now another less effective ointment. Since discontinuing the foam, I have developed chronic tinnitus in my left ear. Nothing has helped. The ENT I visited has basically decided it's just tinnitus and isn't investigating further. Has anyone experienced tinnitus in conjunction with psoriasis in the ears? Thanks for any help!
