Comparative Study
Craniectomy Versus Craniotomy for Posterior Fossa Metastases, Complication Profile.
Surgical resection of posterior fossa metastases (PFM) includes either suboccipital craniotomy or suboccipital craniectomy. The optimal surgical technique is yet to be defined. We examined the association between the chosen surgical approach and the occurrence of postoperative complications. ⋯ Suboccipital craniotomy may be associated with a lower incidence of postoperative morbidity compared with suboccipital craniectomy and should be considered as the preferred approach for the resection of PFM.

The application of stand-alone anchored spacer (SAAS) in anterior cervical discectomy and fusion (ACDF) has been proven to be safe and effective to treat cervical spondylosis. Skip-level ACDF with SAAS, fusing only the involved levels without anterior plates, may be the optimal treatment. The aim of the study was to compare the clinical outcomes, radiologic results of SAAS, and plate-cage construct in the treatment of 2 noncontiguous levels of cervical spondylosis. ⋯ Skip-level ACDF with SAAS is a safe and effective treatment of 2 noncontiguous levels of cervical spondylosis without obvious contraindications, which can keep the IS intact, and have a low impact on the IS.

To evaluate the incidence, clinical presentation, operative techniques, and long-term outcome of spinal cervical meningiomas after surgery. ⋯ Spinal meningiomas are benign tumors for which advances in imaging tools and microsurgical techniques have yielded better results. The goal of surgery should be the total resection, which significantly decreases the risk of recurrence with an acceptable morbidity. Cervical locations represent a challenge particularly for ventro and ventrolaterally located tumors. Despite the difficulty of performing a complete resection, the results obtained in this work advocate for the use of the far-lateral approach to manage meningiomas locate anterior to the neural axis.

To analyze the relationship between clinical factors and spontaneous canal remodeling. ⋯ During posterior fixation, the degree of the reduction of the vertebral body by distraction can affect the degree of postoperative reduction and spontaneous bone remodeling. Therefore, close attention must be given to the indirect reduction technique through distraction during the operation. Because comminuted fracture fragments affect spontaneous canal remodeling, the degree of postoperative resorption can be estimated by preoperative computed tomography imaging.

In elderly patients with severe traumatic brain injury, the use of aggressive versus conservative management remains controversial. The aim of this study was to assess the outcome of surgical alternatives for treatment of severe traumatic intracranial hematoma in patients ≥65 years old and identify factors that may contribute to the outcome. ⋯ This study showed that Glasgow Coma Scale score (≤5) was a major determinant of outcome in elderly patients with severe traumatic brain injury. However, surgical treatment reduced mortality and improved outcome in the elderly patients in this study.
