SURGICAL intervention for the treatment of otosclerosis has created a new interest for the anatomists. The notable studies on the subject are those of Anson, 1 Farrior, 2 Anson and associates, 3 and Kelly 4 who have emphasized the morphological variation of the adult human stapes. A detailed report on the anatomical features and variations of this ossicle has since been reported from this laboratory. 5,6 It was felt worthwhile to continue with a detailed study of the fetal stapes with regard to the various stages of its development. Curiously enough, the very initial study revealed the presence of three separate centers of ossification; a finding contrary to the accepted view of ossification from a single center. This unusual finding aroused our interest and prompted us to examine this ossicle in a large series. This paper deals in particular with the mode of ossification of stapes.
