IN A DISCUSSION of osteogenesis following the fenestration operation in the human ear, in the May 1940 issue of the Archives of Otolaryngology,1 I stated:

From my observations during revisions of the fenestra, I was forced to conclude that new bone regeneration within the fenestra begins not in the periosteal but in the endosteal layer of the bony capsule and either may stop there, without involving the periosteal layer, or may eventually involve the periosteal layer of the bony walls of the fenestra,...

In the November 1947 issue of the Archives of Otolaryngology Lindsay,2 in an analysis of his histologic observations of the results following fenestration of the labyrinth of the rhesus monkey, corroborated the observations which I had made in the human subject and stated:

Failure to maintain an open fistula was in most cases due to the osteogenetic process which took origin from the endosteal surface at the
