Unusual Tullio phenomena

Changes in the Tullio Phenomenon and the Fistula Sign in the Course of Endolymphatic Hydrops

However, to the best of our knowledge, the behavior of saccular and ampullary function has not been studied in association with changes in the Tullio phenomenon or fistula sign during the course of endolymphatic hydrops.…”

An Osteoma of the Middle Ear Presenting with the Tullio Phenomenon

“…This phenomenon has been reported in a range of conditions, including fistulae of the lateral semicircular canal, [24][25][26] the Mondini developmental abnormality, 26,27 endolymphatic hydrops, 28 and the hypermobile stapes syndrome. 29 It has never been reported previously in association with a middle ear osteoma.

Dehiscence Syndrome Superior Semicircular Canal: A Case of Dehiscence Syndrome of the Superior Semicircular

“…Initial clinical studies identified this faith-phe-in patients with syphilis congenital [8]. However, these findings were subsequently demonstrated in conditions such as deafness congé-nita [9] of Ménière [10] syndrome, perilinfática [11] fistula, trauma encefalocraneano [12] of Lyme [13] disease and chronic otitis media with cholesteatoma semicircular [14] channel erosion.…”
