Gradenigo syndrome occurs due to the progression of untreated or partially treated otitis media that spreads to the petrous apex of the temporal bone . The infection is usually caused by Streptococcus pneumoniae, Haemophilus influenzae, Pseudomonas, and Staphylococcus aureus. The causative organism travels from the middle ear to the mastoid air cells , which contain a highly vascular marrow. It can then spread to the adjacent petrous temporal bone and the surrounding vital structures such as the trigeminal ganglion and abducens nerve.
