A novel approach for surgical repair of dehiscent high jugular bulb.
INTRODUCTION The jugular bulb is found at the junction of the horizontal segment of the sigmoid sinus and the superior end of the internal jugular vein. A high jugular bulb (HJB) may extend into the middle ear cavity lateral to the cochlea. The superior threshold of HJB varies according to various authors. The limits include the inferior bony annulus, the lower border of the round window, and t...

متن کاملSurgical Exposure Gained in an Extended Retrosigmoid Approach to the Cerebellopontine Angle Compared to the Traditional Retrosigmoid Approach.
AIM Retrosigmoid approach to the posterior fossa has been a popular and dependable approach for accessing the cerebellopontine angle (CPA) and petroclival region. Although this approach is commonly used, it requires cerebellar retraction and has limitations when the lesion is located ventral to the brainstem. The aim was to quantify the angle of view provided by extended retrosigmoid approach i...
متن کاملTransmastoid retrosigmoid approach to the cerebellopontine angle: surgical technique.
BACKGROUND The traditional suboccipital craniotomy in the retrosigmoid approach gives limited exposure to the cerebellopontine angle (CPA) structures and necessitates cerebellar retraction, whereas the addition of drilling of the mastoid process with reflection of venous sinuses offers wider exposure of the CPA and avoids cerebellar retraction. We describe the details of the surgical technique ...
