Adaptation of virtual surgical planning to midface reconstruction with intraoperative navigation: "navigation mediated midface reconstruction".

Objective: The production of 3-dimensional models and materials according to preoperative virtual surgical planning is a time-consuming process and causes high costs. We aimed to demonstrate the navigation mediated reconstruction of the patients who underwent the removal of a tumoral mass in midfacial region according to their preoperatively prepared surgical plannings.

Study Design: Patients who underwent the removal of tumoral mass and reconstruction in their midfacial region were included in the study.

Cerebral Vasospasm after Posterior Fossa Tumor Surgery: A Case Report and Literature Review.

Introduction: This report presents an unusual case of symptomatic vasospasm following resection of posterior fossa tumor in a 9-year-old female patient. To the best of our knowledge, only 6 pediatric cases of vasospasms as a complication of brain tumor surgery have been reported in the literature previously.

Case Presentation: After an uneventful 12 days postoperatively, the patient suddenly presented with acute neurological deterioration on the 13th day and MR angiography showed bilateral narrowing of the supraclinoid segments of the internal carotid artery and the proximal parts of the A1 and M1 segments.

Intraoperative Neurophysiologic Monitoring for Lumbar Intradural Schwannomas: Does It Affect Clinical Outcome?

Objective: Intraoperative multimodal neuromonitoring (IONM) is considered valuable for the early detection and prevention of any neurologic compromise during spine surgery. It has also become the standard of care at many institutions to improve the surgical outcome and be a safety net for both clinical and medicolegal concerns.

Methods: Our experience and outcomes in 46 consecutive cases of lumbar intradural schwannoma resection were reviewed with respect to clinical outcomes and patient safety, before and after the integration of IONM into our clinical practice.

Clivus metastasis of squamous cell carcinoma: a rare location.

Lung cancer is the most frequently encountered cancer in humans and commonly metastasizes to brain and bone. Metastasis to the clivus is very rare and there have been no previous reports. A 51-year-old woman was admitted to our hospital complaining of headache, and left shoulder, arm and back pain.

Enhanced frontalis sling with double-fixed, solvent-dehydrated cadaveric fascia lata allograft in the management of eye ptosis.

The article describes an enhanced frontalis sling procedure in the management of blepharoptosis with poor or no levator function. This modified method were used in the care of three patients and based on the principal of two-point fixation of the graft material that was prepared from solvent-dehydrated cadaveric fascia lata onto the frontalis muscle. After more than 1 year of follow-up, no recurrence was noted.
