The early efforts of Jenkins1 and Bárány1a and the recent efforts of Holmgren2 and Sourdille3 to ameliorate deafness in cases of otosclerosis by surgical means have led to the conclusion that when improvement in hearing has been obtained by the making of a new fenestra in the bony capsule of the labyrinth the early closure of this labyrinthine fistula by bony regeneration must be prevented surgically in order to maintain this improvement in hearing permanently.
Sourdille,4 who performs what he terms a tympanolabyrinthopexy in three principal stages at intervals of four or five months, stated:
In a great number of cases, unfortunately, the success is ephemeral: four, six, or ten weeks later, one sees the aerial hearing diminish, the Rinne becomes negative and the Weber indifferent. At the same time, the air pressure in the meatus can attain 40 and even 60 cm. of water without determining nystagmus, nor a
