Intracranial epidermoid tumors are epithelially derived lesions that may present particular challenges to neurosurgeons, often encasing critical neurovascular structures and extending into multiple subarachnoid cisterns. We aimed to evaluate our recent experience with endoscopic assistance to craniotomy with microsurgical resection of these lesions. ⋯ The endoscope is a safe and effective adjunct to the microscope in facilitating additional inspection and further resection of epidermoid tumors. Endoscopic-assisted surgery is particularly useful for identifying and removing additional tumor located around surgical corners.

To delineate the learning style that best defines a successful practitioner in the field of neurosurgery by using a validated learning style inventory. ⋯ The assimilating and diverging learning styles are the preferred learning styles among neurosurgeons, neurosurgery residents, and neurology residents. The assimilating learning style typically is the primary learning style for neurosurgeons and neurology residents. Neurosurgical residents start off with a diverging learning style and progress toward an assimilating learning style as they work toward becoming practicing neurosurgeons. The field of neurosurgery has limited opportunities for active experimentation, which may explain why individuals who prefer reflective observation are more likely to succeed in this field.

James L. Poppen and surgery of the "seat of the soul": a contemporary perspective.
Dr. James Leonard Poppen (1903-1978) was one of the most renowned American neurosurgeons of the 20th century. The now eponymous Poppen approach to the pineal region is still used routinely in current neurosurgical practice. ⋯ He retired from this post in 1970; however, he continued his practice of neurosurgery until his death. This historical vignette aims to highlight the work of James L. Poppen and the evolution of the surgery of the "Seat of the Soul." His work has had a lasting influence on neurosurgeons and neuroscientists over the years.

To describe a new technique for safe drilling of the posterior wall of the internal auditory canal (IAC), in which the intact posterior lip of the internal auditory meatus is used as a fixed intraoperative reference point to preserve the integrity of labyrinthine structures. ⋯ Adequate drilling of the posterior wall of the IAC could be achieved, and tumor excision with hearing preservation was obtained by meticulous intraoperative planning and measurements based on preoperative computed tomography scanning and by keeping the intact posterior lip of the internal auditory meatus as a landmark for safe drilling.
