Microsurgical Resection of Trigeminal Schwannoma via Anterior Petrosal Approach: 2-Dimensional Operative Video.
Trigeminal schwannomas are complex lesions that may be related to many critical neurovascular structures. We present the case of a 59-year-old male presenting a history of left-sided trigeminal neuralgia. Preoperative imaging demonstrated a mass highly suggestive of a trigeminal schwannoma, and microsurgical resection was indicated considering the progressive symptomatology and important mass effect (Video 1). ⋯ The patient's symptoms improved, and there were no neurologic deficits on follow-up. Extensive laboratory training is fundamental to be familiarized with the normal anatomic nuances and prepared to face the anatomy distorted by lesion. Informed consent was obtained from the patient for the procedure and publication of this operative video.

The purpose of the present study was to investigate the mechanism of pituitary fibrosis in elderly people. ⋯ Pituitary fibrosis was found in the elderly group, and the pathological change was antagonized by decreasing the proinflammatory cytokine levels using QNZ and further increasing GH secretion.

Cervical disk protrusion is a common pathology. Anterior diskectomy and fusion is considered the gold standard of treatment, although anterior arthroplasty has gained some acceptance in the past decade as an alternative. Posterior cervical minimally invasive diskectomy is a rarely used technique, and there is less literature discussing this procedure. ⋯ A 5-mm smooth diamond drill is used to perform a foraminotomy. To avoid nerve root or spinal cord manipulation, it is often necessary to remove some of the rostral aspect of the inferior pedicle to gain access to the axilla and disk protrusion. The procedure is rapid, well tolerated, and performed as outpatient, and it results in a rapid return to normal activity.
