Sections:
The sinus tympani of the petrous temporal bone is a small recess in the posterior wall of the mesotympanum medial to the pyramidal eminence and stapedius muscle origin. Lateral to the pyramidal eminence is the facial recess.
It is of surgical importance due to its invasion by cholesteatoma and difficulty in surgical visualization.
