AbstractVariability in the size of the dural sinuses and jugular bulb is not uncommon and usually manifests as a high jugular bulb encroaching upon the floor of the middle ear. A rarer entity is the superior and medial extension of the jugular bulb into the bone of the posterior wall of the internal auditory meatus. We report a case where this anomaly was encountered during acoustic neuroma surgery making exposure of the fundus of the internal auditory meatus technically impossible. The possibility of a communication with the superior petrosal sinus is discussed.

A temporal bone histopathological study was conducted to detect temporal bone anomalies in 20 ears (10 cases) of individuals with congenital heart anomalies. We restricted our study to patients more than one year of age, and to heart anomalies of unknown etiology. The temporal bones were obtained from refrigerated cadavers, fixed in formalin, embedded in celloidin, cut in a horizontal plane, stained with H & E, and mounted on glass slides for light microscopic study. Anomalies observed in the middle ear were: remnants of mesenchymal tissue (8 ears), wide angle of the facial genu (6 ears), persistence of the stapedial artery (5 ears), large defect of the facial canal (4 ears), high jugular bulb (4 ears), and bulky incus (2 ears). Inner ear anomalies consisted of a shortened cochlea (5 ears), anomaly of the horizontal canal (3 ears), anomaly of the posterior canal (2 ears), obliteration of the cochlear aqueduct (2 ears), and patent utriculoendolymphatic valve (1 ear). Most of the anomalies observed appeared to be due to arrested development, and resembled features which may be found at various stages of fetal life. Structural anomalies were more commonly found in the mesoderm than in the ectoderm, and middle ear anomalies were more frequently encountered than anomalies of the inner ear. No definite relationship between these anomalies observed in the temporal bone and hearing problems which had been recorded clinically for these patients could be detected. However, the large defect (more than one third of the circumference) of the facial canal, the high jugular bulb, and the stapedial artery persistence should be recognized as problems since they may be encountered during middle ear surgery.

The suboccipital-retrosigmoid approach to the internal auditory canal and cerebellopontine angle is being used with increasing frequency for neurotologic surgery, including vestibular nerve section and resection of acoustic neuroma. It offers wide exposure of the cerebellopontine angle and the cranial nerve VII—VIII complex as it courses from the brain stem to the temporal bone. Exposure of the internal auditory canal can be achieved by removing its posterior bony wall. Safe utilization of this approach requires familiarity with the variable position of structures within the petrous bone, including the lateral venous sinus and jugular bulb. We report here a case in which bleeding resulted from injury to a high jugular bulb during surgical exposure of the internal auditory canal via the suboccipital route and discuss the regional anatomy of the jugular bulb based on study of 378 consecutive temporal bone specimens from the collection of the Massachusetts Eye and Ear Infirmary. High jugular bulb was defined as encroachment of the dome of the bulb within 2 mm of the floor of the internal auditory canal. Forty-six percent of scoreable specimens met this criterion. However, when donors less than 6 years of age were excluded, a high jugular bulb was identified in 63% of specimens. Relevance to neurotologic surgery of the posterior fossa is presented.

Nonneoplastic vascular lesions in the middle ear may be arterial or venous. For the former, ectopic location of the internal carotid artery is the most common; a high jugular bulb is the most common venous abnormality. Both may be clinically misdiagnosed without radiographic studies and, in the event, lead to disaster.

Pulsatile tinnitus (PT) caused by a high-riding dehiscence jugular bulb (HDJB) is a rare but treatable otology disease. There are several managements include transcatheter endovascular coil embolization, transvenous stent–assisted coil embolization, or resurfacing the dehiscent bony wall of high jugular bulb under the use of microscope. Among those options, surgical resurfacing of HDJB might be an effective and safe choice with less destruction. However, previous studies approached middle ear cavity via microscope can only provide a lateral, indirect view, while resurfacing the vessel through a transcanal endoscopic ear surgery (TEES) approach may give surgeon a direct and easy way to manage HDJB. In this report, we presented a case of 40-year-old woman with HDJB and shared our clinical consideration and reasoning of the surgical management of PT via a transtympanic approach by TEES rather than a transmastoid approach.

AbstractEncounters with the jugular bulb in ear surgery are uncommon. This communication relates three cases where the author was confronted with the bulb in middle ear surgery – one in relation to the external auditory canal when raising a tympanomeatal flap and two in the hypotympanum when entering the middle ear. The anatomy of the jugular bulb is considered, particularly in regard to its quite variable placement within the temporal bone. The manner of clinical presentation of the high jugular bulb and previous cases in the literature where the jugular bulb has been discovered in juxtaposition to the surgical approach are discussed. Implications of surgical management are considered.

Glomus tumours of the temporal bone occur in the region of the jugular bulb and middle ear. Theyare rare, highly vascular, slow growing tumours and most are benign. Tumours that originate from the jugular bulb andextend to involve the middle ear are referred to as glomus jugulare tumours. Those that are found in the middle eararound the otic ganglia in the tympanic plexus are known as Glomus tympanicum. These tumours occur predominantlyin women in the fifth and sixth decades of life. Because of the insidious onset of symptoms, these tumours often gounnoticed and there is often a significant delay in diagnosis. Morbidity in these cases is determined by their size andposition. Objectives: 1. To study the age/sex incidence of patients suffering from glomus tumours of the temporalbone. 2. To see various clinical presentations with which these tumours present and their variation according to theage and sex. Design: Our study design was non-inter-ventional descriptive. Settings: This study was performed atCMH Rawalpindi and Multan from January 2000 to June 2002. Subjects: We included ten patients of glomus tumoursof the temporal bone in our study. 8 out of these were females and two were males. Though most of the patientsbelonged to middle age group yet few were also from the younger and older groups. Interventions: All the patientsunderwent CT scan with and without contrast, MRI of the requisite site and carotid angiography. Results: We foundthat these tumours were predominantly present in females, mostly in the middle age group. Individual symptoms werestudied in detail and their presence was found to be directly proportional to the increasing age of patients. Conclusion:It is concluded that due to the slow growth of this tumour the diagnosis is often delayed until it is extensive. Thereforeclinicians should be more vigilant about this rare disease and must keep it in their differentials.
