New morphometric findings in adhesive otitis media: Petroclival angle and eustachian tube-tympanic cavity ventilation angle

More medially positioning of the petrous bone and acutely angled-eustachian tube-tympanic cavity ventilation axis were observed in this study. It would be reasonable to conclude that these findings might take part in development of adhesive OM. We should also admit that these results do not decline the previous theories that account for development of the adhesive otitis media.
