- Source: Promontory of tympanic cavity
The promontory of the tympanic cavity, also known as the cochlear promontory is a rounded hollow prominence upon - and most prominent feature of - the medial wall of the tympanic cavity formed by the underlying first turn of the cochlea. The surface of the promontory is furrowed by fine grooves that accommodate to the strands of the tympanic plexus.
The oval window is situated superoposteriorly to the promontory, and the round window inferoposteriorly to it.
A minute spicule of bone frequently connects the promontory to the pyramidal eminence.
