Jugular bulb diverticulum is a rare diagnosis, as fewer than 50 cases have been reported in the literature. It has been reported that unilateral auditory symptoms may accompany this entity, although some patients are asymptomatic. We present a case series of 3 patients who were referred to our tertiary care neurotology center with a unilateral jugular bulb diverticulum along with unilateral sensorineural hearing loss and tinnitus. These patients were evaluated clinically and radiographically. This case series (1) adds further documentation of the presence of unilateral auditory symptoms in patients with a jugular bulb diverticulum and (2) demonstrates the value of computed tomographic venography in the diagnosis of jugular bulb diverticulum.

OBJECTIVE: To report the case of a 52 year-old-woman presenting with a left mixed hearing loss. Surgical exploration revealed an attical fixation of the malleus head associated with obliteration of the round window by a high jugular bulb. METHOD: Surgical exploration revealed this rare association. Attical fixation of the malleus head was treated by a partial prosthesis. The mobility of the chain was normal at the end of the surgical exploration but it was not possible to search for the round window sign because the niche of the round window was obliterated by an high Jugular bulb. RESULTS: Audiogram was unchanged even if CT-scan confirm the good position of the partial prosthesis. CONCLUSION: Surgical treatment of an attical fixation of the malleus head do not seem to be necessary if it is associated with a simultaneous obliteration of the round window. Indeed, obstruction of the round window by a high Jugular bulb can caused a conductive hearing loss.

OBJECTIVE: To differentiate and treat correctly the jugular bulb anomalies, as well as to avoid the unnecessarily enlarged operations. METHODS: Four cases of jugular bulb anunalies were reported and analysed. RESULTS: Two of 4 cases were misdiognosed as jugular glomus tumors; One was considered to be jugular bulb anomaly, but was done with an enlarged operation; another one was still accompanied with benign intracranial hypertension syndrome, was inappropriately treated. CONCLUSION: The jugular bulb anomaly was often misdiagnosed, therefore the anomaly should be differentiated from the jugular glomus tumor carefully.
