HIGH RIDING JUGULAR BULB. IDENTIFY AND BE CAUTIOUS.

Dr. Kc Prasad, Dr Anjali Pk

Abstract :

The jugular bulb is the dilated internal jugular vein at the jugular foramen at skull base, which drains transverse and sigmoid sinuses which develops in early childhood. When the sigmoid plate is dehiscent It leads to dehiscent jugular bulb which bulges into middle ear cavity.Jugular bulbis ideally below the hypotympanum. It is called high riding jugular bulb when it comes in the middle ear or reaches superior to tympanic annulus encroaches within 2mm of Internal auditory meatus.  If the jugular bulb is dehiscent surgeon should be careful while elevating the tympanomeatal flap or else might end up in torrential bleeding. In some conditions it might be forming the inferior wall if the middle ear and external auditory canal. High jugular bulb is not a contraindication for middle ear surgery, but the surgeon should be well aware whether to continue with the surgery or to abandon before complications occur. If it’s found impinging on the ossicles or round window niche better to abort the procedure.
