The high jugular bulb

P J Gullane, R R Ruby, F J Rounthwaite

The Journal of Otolaryngology

|October 1, 1976

Summary

This summary is machine-generated.

High jugular bulb, a rare anatomical variation, can present as an external auditory canal mass. Polytomography aids in diagnosing this condition, which can mimic benign tumors.

Background:

The jugular bulb is a venous structure that can exhibit anatomical variations.
A high jugular bulb is an uncommon variation where the bulb extends superiorly.
Understanding these variations is crucial for accurate diagnosis and management of ear canal pathologies.

Observation:

This report details three cases of high jugular bulb.
One case presented as an external auditory canal mass, mimicking an osteoma.
This presentation is believed to be the first documented instance of a high jugular bulb manifesting in the external auditory canal.

Findings:

Clinical manifestations of high jugular bulb were described.
The diagnostic utility of polytomography was highlighted.

Related Experiment Videos

Polytomography proved valuable in identifying the high jugular bulb and differentiating it from other masses.

Implications:

This case expands the differential diagnosis for external auditory canal masses.
Awareness of high jugular bulb presentation can prevent misdiagnosis and unnecessary surgical intervention.
Polytomography should be considered in the diagnostic workup of external auditory canal masses with atypical features.
