Glomus Tumor Case Number 2

1) View of the eardrum through the ear canal. No incisions are made in the skin behind the ear—the approach is completely through the ear canal utilizing a high-magnification operating microscope. The eardrum is examined and there is a reddish mass seen in the middle ear cavity just inside of the eardrum. This is a glomus tympanicum tumor and it is just barely touching the eardrum.
2) An additional view of the glomus tympanicum tumor within the middle ear, which is indicated by the white arrow. The black arrowhead is pointing towards one of the middle ear hearing bones that can be seen through the eardrum—this is the incus, the second hearing bone commonly called the “anvil” (hammer-anvil-stirrup).
3) The eardrum has been reflected up, much like the hood of a car is lifted.  Inside of the eardrum, the contents of the middle ear are clearly visualized, including the incus and stapes hearing bones (black arrow).  The white arrow indicates the glomus tympanicum tumor that originates from the promontory of the inner ear.  This vascular tumor originates from cells surrounding blood vessels.

4) Using CO2 laser technology, the glomus tumor is removed.  There is little bleeding and the excision is very precise because of the laser technology utilized.  The origin of the tumor is also lased with the CO2 laser.

5) The eardrum is replaced. A slight amount of packing is used in the ear canal and the procedure is completed.
