Some anatomical remarks on the posterior region of the tympanic cavity.
The Authors have studied the posterior region of the tympanic cavity in 25 fresh human temporal bones, making horizontal and vertical sections. In all cases the Sinus Tympani has been observed and the same for the Sappey's Suprapyramidal Recess, near the Facial Sinus. It has been determined the distance between Sulcus Tympani and the facial canal which is very variable and this assumes great importance from a surgical point of view.
