Middle Ear, Chronic Suppurative Otitis, Surgical Treatment: Workup
Updated: Oct 22, 2009
Workup
Laboratory Studies
- If an unusual organism such as Tuberculosis is suspected, a culture and sensitivity is appropriate.
- Other routine studies should be performed as are required for general anesthesia at the treating hospital.
Imaging Studies
- CT scans can be obtained in selected cases, such as when the patient reports vertigo and before revision surgery. Although not necessary, the CT scan can alert the surgeon to dehiscents of the semi-circular canals or facial nerve.
- MRI might be appropriate upon suspicion of dural herniation or extensive cholesteatoma extending into the petrous apex.
Other Tests
Preoperative complete audiograms should be obtained, ideally within 3 months of surgery.
