The Endolymphatic and Perilymphatic Aqueducts of the Human Ear: Developniental and Adult Anatomy of their Parietes and Contents in Relation to Otological Surgery

Abstract

The fetal development of both the vestibular and cochlear aqueducts will be followed in otological series beginning with tlie 4-month stage. Postnatal progress and mature structure will be traced from the newborn infant to the adult of 70 years (in dissections, serial sections and reconstructions prepared from the latter).

These features will be emphasized: histology of the osseous wall and the contained connective tissue; source and course of blood vessels derived from labyrinthine periotic tissue internally and meningeal layers externally; normal range in adult anatomy. On these structural bases, the two channels will be compared, with special reference to their present and prospective role in otological surgery.
