The fate of an ossicular allograft in tympanoplasty.

Ben H. Senturia lecture. Leaking labyrinth lesions, deafness, tinnitus and dizziness.

Such leaking labyrinth lesions can be congenital origin, due to various types of malformations. They may be caused by destructive diseases such as syphilis, by many variants of acute and chronic otomastoiditis, and sequelae of otosclerosis surgery, and finally, as results of a variety of traumatic disruptions of labyrinthine integrity.
