gasserian gas·ser·i·an (gā-sēr'ē-ən)
Of, relating to, or described by Austrian anatomist Johann Ludwig Gasser (1723-1765).
So far as its pathology is known, it is believed to be due to degenerative changes in the semilunar (gasserian) ganglion.
He may not be able to excise a gasserian ganglion, or know very much about the researches of Calmette or von Pircquet.
A large ganglion becomes developed close to the root, which forms the rudiment of the gasserian ganglion.
