Each patient in the trial underwent right retromastoid
craniectomy and microvascular decompression.
looked at blood pressure in patients who underwent surgery ("left retromastoid
craniotomy and microvascular decompression") to treat cranial nerve dysfunctions.
The patient's head was then positioned facing the right in order to allow access to the left retromastoid region.
Using native fluoroscopic roadmap guidance and sterile ultrasound, the arterialized venous pouch lying along the left retromastoid calvarium was punctured with a 21-gauge micropuncture needle.
The patient underwent an open biopsy via a retromastoid approach, and analysis of the specimen identified it as a hemangiopericytoma.
A standard extended retroauricular incision was made from the midtemporal area through the retromastoid area (incorporating the previous biopsy incision) and then carried medially across the anterior border of the sternocleidomastoid muscle (figure 2).
Through a retromastoid
incision the muscle, fascia, and pericranium are dissected away from the calvaria.
In 1994, he underwent a retromastoid
craniectomy with an extended cyst resection on the left.
