Objectives To present nine patients with an abnormal widened bony Eustachian tube running anteriorly in the skull base through the sphenoid bone. Methods Patients with a particular anomaly in the bony Eustachian tube incidentally found on CT examinations were registered consecutively over a period of four years. Results Nine patients had the anomaly, eight unilaterally and one bilaterally. All our patients had additional anomalies involving the outer, middle, and/or inner ear. Conclusion The consequences of this anomaly remain unknown, but the presence of the widened, bony ET should increase the awareness for complex temporal bone deformities and vice versa. Level of Evidence 4.
