Glomus tympanicum magnified.
-
This patient presented with a history of severe bleeding from the placement of a PE tube in her right ear. On examination, the posterior half of the tympanic membrane was red and pulsating.
-
Surgical picture of the above patient. A tympanomeatal flap has been elevated and reflected anteriorly to expose the glomus tympanicum that filled the posterior half of the middle ear space.
