The author studied anatomical variations of the origin of the chorda tympani
nerve from the mastoid portion of the facial nerve. The studies were performed on
200 specimens of human temporal bone. It was found that the chorda tympani may
arise from the facial nerve in three levels: most commonly from the mid third of its
mastoid segment (70%), less commonly from the proximal third (20%), and very
rerly from the distal third (10%). Knowledge of these variations has a certain value
in surgical intervention of the middle ear.
