Two injections were administered in the right and left suboccipital area (exactly at
retromastoid cervicocranial junction) and the other two in the lower medial frontal area (exactly at medial right and left eyebrows).
One year after resection, axial 3D T1-weighted contrast-enhanced MRI of the brain (d) demonstrates interval postsurgical changes of right
retromastoid craniotomy for resection of the right cerebellopontine angle tumor without evidence of residual tumor.
All the patients were operated through a
retromastoid suboccipital approach by a single surgeon under the microscope who has been doing the procedure since last ten years.
2: MRI brain and cervical region) a 4 x 6 cms irregular shaped and ill-defined bordered tumor present in left temporal bone (mastoid) which is extending into jugular foramen anteriorly,
retromastoid suboccipital region posteriorly and extending down into the neck upto C2 transverse process.
Type A tumors may be accessed via a
retromastoid approach.
looked at blood pressure in patients who underwent surgery ("left
retromastoid craniotomy and microvascular decompression") to treat cranial nerve dysfunctions.
Results: Petroclival region can be accessed through following approaches: petrosal, anterior and posterior combined approach, supra and infratentorial combined presigmoid approach, orbito-zigomatic infratemporal approach, suprameatal intradural retrosigmoid approach, pterional approach,
retromastoid approach, subtemporal approach and combined subtemporal
retromastoid approach:
The patient underwent an open biopsy via a
retromastoid approach, and analysis of the specimen identified it as a hemangiopericytoma.
Through a
retromastoid incision the muscle, fascia, and pericranium are dissected away from the calvaria.
Each patient in the trial underwent right
retromastoid craniectomy and microvascular decompression.
All except 1 patient underwent
retromastoid retrosigmoid suboccipital craniectomy.
He underwent right side suboccipital
retromastoid craniectomy.
