[The morphological and morphometric study of the segment of the labyrinth of the fallopian canal]

The study of the Fallopian canal with bone specimens can offer an exact and valuable information on the morphology of this duct and its close relations with neighbouring structures. The aim of this paper is to give an actualized compilation of the updated know findings, regarding the morphology and the morphometry of the first segment of the Fallopian canal. The study is based on 92 human temporal bones coming from skulls of adult subjects of both sexes. After a careful drilling work the whole length of the canal, that of the I.E.C. and the corresponding to the labyrinthine segment as well, were exposed and measured. The results allowed the AA. the macroscopical checking of the inversed ratio between the length and the calibre of the investigated canals. The labyrinthine portion of the facial canal is more narrow at its beginning (at the bottom of the I.E.C.) becoming broader as the duct approaches the first knee (geniculated ganglion) of the nerve.
