The lateral extended transsphenoidal endoscopic approach (LETEA) is used to remove tumors located lateral to the cavernous segment of the internal carotid artery under direct visual control and provides access to Meckel cave, pterygopalatine fossa, medial part of the middle cranial fossa, and orbit. We describe an extended transsphenoidal approach to the amygdalohippocampectomy through the pterygopalatine fossa. ⋯ LETEA through the pterygopalatine fossa is minimally invasive and provides direct access to the temporal pole and medial part of the temporal lobe. This approach may reduce risk of neurologic deficit and help to avoid cosmetic defects in the frontotemporal region associated with injury to temporal muscle and facial nerve injury as can occur during transcranial approaches. Disadvantages that limit application of LETEA include risk of cerebrospinal fluid leak and skills needed for manipulation in a narrow and deep surgical field with angled 30° and 45° endoscopes.

Historical Article
The History of Neurosurgery at the National Hospital, Queen Square, London. With some personal recollections from 1948 onwards. The Early Years.
The National Hospital, Queen Square, London was founded as a charitable institution in 1860, becoming the first dedicated neuroscience hospital in the world. Sir Victor Horsley, the first neurosurgeon was appointed in 1886, and since that time, Queen Square neurosurgeons have been prominent on the World neurosurgical stage, including Sir Wylie McKissock and Prof Lindsay Symon, inter alia. This article gives the history taken from both published records and personal stories, recorded by a neurosurgeon who has worked at the hospital for thirty five years.

Comparative Study
Long Term Outcome After Conservative Treatment and Direct Bypass Surgery of Moyamoya Disease at Late Suzuki Stage.
To investigate the long-term outcomes after conservative and direct surgical treatment for patients with moyamoya disease (MMD) at late Suzuki stage. ⋯ Although direct bypass surgery was shown to effectively improve the cerebral perfusion in patients with MMD at late Suzuki stage, compared with conservative treatment, it did not reduce the risk of recurrent stroke. Further study is needed to determine whether direct bypass surgery is effective in patients with MMD at late Suzuki stage.

To investigate risk factors and complications of cervical spine surgery in elderly patients. ⋯ Patient comorbidities and clinical factors, such as longer operating time and emergency cases, impact risk of adverse events. Patients 70-74 years old and patients with at least 1 postoperative complication had an increased risk of unplanned readmission.

Insular gliomas are challenging tumors to surgically resect owing to the anatomy surrounding them. This study evaluates the role of extent of resection (EOR) and molecular markers in surgical outcome and survival for insular gliomas. ⋯ Extensive resections of insular gliomas can be achieved with low morbidity and can improve overall survival and PFS. In this series of LGGs, EOR was associated with longer malignant PFS, and 1p/19q codeletion was predictive of PFS.
