Adhesive Otitis Media
- Lack of middle ear ventilation results in negative pressure within the tympanic cavity
- The ear drum retracts onto structures within the middle ear
- The result of long standing Eustachian tube dysfunction
- The drum loses structural integrity and becomes flaccid
- Contact between the drum and the incus or stapes can cause bone erosion at the IS joint
- Can sometimes be treated with tympanostomy tubes
