High Jugular Bulb

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.

ABSTRACT The external auditory canal (EAC) is formed by lateral cartilaginous and medial bony part. The stenosis of EAC is narrowing of the width of the EAC, i.e. either caused by congenital or acquired causes. Myringosclerosis is a condition caused by calcification of tissues in the tympanic membrane and ossification is a special form of fibrosis due to the long-term, irreversible continued inflammation in the middle ear cleft. We are presenting rare case of idiopathic tympanic membrane ossification with generalized stenosis of EAC in 29-year-old patient. How to cite this article Verma H, Dass A, Singhal SK, Gupta N.

Polypoidal Mass

<p>Foreign body in ear is an emergency encountered by an otolaryngologist and if not removed it can lead to serious complications. Most commonly foreign body in ear is lodged in external auditory canal while it’s rare to find it in middle ear. We report a case of foreign body in the middle ear in a 3-year-old child who presented to us with chronic discharging ear who was then suspected to be unsafe ear and so was taken up for exploration under microscope. A pink polypoidal mass arising from middle ear mucosa was found and following its removal- to our surprise; a blackish rubbery debris filling the middle ear cavity and attic area along with embedded foreign body was extracted. We conclude that pediatric patients with chronic ear discharge not responding to antibiotics should raise a suspicion of FB in the middle ear and explored timely.</p>

Three patients with extensive keratosis obturans were treated during a 12-month period. One presented with an idiopathic sensorineural hearing loss and was found to have keratosis obturans in the contralateral, asymptomatic ear. The disease process had resulted in a horizontal semicircular canal fistula in what was now, effectively, the only hearing ear. The second patient had an extensive dehiscence of the tegmen tympani. The third presented with a facial palsy. An automastoidectomy cavity was present, with circumferential skeletonization of the descending facial nerve over a length of 1.5 cm and dehiscence of the temporomandibular joint and jugular bulb. All three patients were successfully treated by surgical formalization of their automastoidectomy cavities. They appeared to represent cases of keratosis obturans rather than external auditory canal cholesteatoma, on the basis of previously published reports.These complications and patterns of bone erosion have not previously been described in keratosis obturans. The third patient is believed to have the most extensive case of keratosis obturans yet described.

OBJECTIVEThere is no definitive or consensus classification system for the jugular bulb position that can be uniformly communicated between a radiologist, neurootologist, and neurosurgeon. A high-riding jugular bulb (HRJB) has been variably defined as a jugular bulb that rises to or above the level of the basal turn of the cochlea, within 2 mm of the internal auditory canal (IAC), or to the level of the superior tympanic annulus. Overall, there is a seeming lack of consensus, especially when MRI and/or CT are used for jugular bulb evaluation without a dedicated imaging study of the venous anatomy such as digital subtraction angiography or CT or MR venography.METHODSA PubMed analysis of “jugular bulb” comprised of 1264 relevant articles were selected and analyzed specifically for an HRJB. A novel classification system based on preliminary skull base imaging using CT is proposed by the authors for conveying the anatomical location of the jugular bulb. This new classification includes the following types: type 1, no bulb; type 2, below the inferior margin of the posterior semicircular canal (SCC), subclassified as type 2a (without dehiscence into the middle ear) or type 2b (with dehiscence into the middle ear); type 3, between the inferior margin of the posterior SCC and the inferior margin of the IAC, subclassified as type 3a (without dehiscence into the middle ear) and type 3b (with dehiscence into the middle ear); type 4, above the inferior margin of the IAC, subclassified as type 4a (without dehiscence into the IAC) and type 4b (with dehiscence into the IAC); and type 5, combination of dehiscences. Appropriate CT and MR images of the skull base were selected to validate the criteria and further demonstrated using 3D reconstruction of DICOM files. The microsurgical significance of the proposed classification is evaluated with reference to specific skull base/posterior fossa pathologies.RESULTSThe authors validated the role of a novel classification of jugular bulb location that can help effective communication between providers treating skull base lesions. Effective utilization of the above grading system can help plan surgical procedures and anticipate complications.CONCLUSIONSThe authors have proposed a novel anatomical/radiological classification system for jugular bulb location with respect to surgical implications. This classification can help surgeons in complication avoidance and management when addressing HRJBs.
