Review Case Reports
Endoscopic Transvestibular Transmandibular Approach for Trigeminal Schwannoma in Infratemporal Fossa and Parapharyngeal Space.
Schwannomas that involve the mandibular division of the trigeminal nerve and localize exclusively in the parapharyngeal space (PPS) and infratemporal fossa (ITF) are extremely rare, and a surgical approach to treat such tumors has not been well established. ⋯ Schwannomas located in the ITF and PPS are rare benign neoplasms. They are usually detected late after considerable signs and symptoms appear. Preoperative planning is beneficial to individual surgical approach selection. Total surgical excision following careful evaluation of preoperative computed tomography and magnetic resonance images is the treatment of choice. Recurrence is rare after complete excision.

Intracranial meningiomas are the most commonly diagnosed brain tumor in the United States. With increasing incidence, efficient allocation of limited health care resources is a critical component of emerging value-based models of care. The purpose of this study was to evaluate the effect of patient and hospital variables on metrics of value-based care. ⋯ This statewide population analysis of readmissions, mortality, length of stay, and hospital charges after intracranial meningioma surgery identified patient predictors of adverse outcomes. These determinants may be used by hospitals to develop improved systems of care in at-risk populations.

Infectious intracranial aneurysms (IIAs) are a rare but potentially devastating complication of infective endocarditis. The clinical and radiographic findings that predispose patients to IIA remain poorly understood. ⋯ Presence of hemorrhage on noninvasive imaging and history of IVDU are independently predictive of IIA presence in patients with infectious endocarditis. Risk stratification using these 2 factors may help identify the most vulnerable populations for IIA formation.

Observational Study
Clinical Outcome of Epidural Hematoma Treated Surgically in the Era of Modern Resuscitation and Trauma Care.
Patients from contemporary populations with traumatic brain injury (TBI) resulting from epidural hematoma (EDH) may differ regarding age, comorbidities, and coagulation status. We therefore analyzed predictors for the clinical outcome of patients with EDH treated surgically regarding modern approaches to resuscitation and trauma care. ⋯ The outcome for EDH is more favorable than decades ago, most probably reflecting a well-established chain of trauma care. Therefore, EDH is a treatable disease with a high probability of a favorable outcome.

Meralgia paresthetica is a mononeuropathy of the lateral femoral cutaneous nerve (LFCN) caused by compression around the inguinal ligament. We report a surgical alternative for the treatment of meralgia paresthetica under local anesthesia and its outcomes. ⋯ Symptoms of meralgia paresthetica can resemble those of a lumbosacral disorder. Microsurgical deep decompression under local anesthesia produces good surgical outcomes. The use of local anesthesia contributes not only to reduction of pain during surgery but also eliminates excessive surgical procedures and reduces the duration of hospital stay.
