The fusiform gyrus and the collateral sulcus are the anatomical structures located in the temporobasal region. In this study, the topographic anatomy of the fusiform gyrus and the collateral sulcus is detailed to make a contribution for a successful course of temporal lobe surgery. ⋯ The topographic anatomy of the collateral sulcus with its surrounding structures is detailed in this study. This study clarifies and supplements the knowledge presently available to help develop a more feasible surgical concept.

Awake craniotomy (AC) is generally a safe and effective procedure; however, a small but not insignificant portion of cases are aborted due to patient intolerance of the awake portion of surgery. There is not yet a firm understanding of what characteristics indicate patient tolerance or failure of AC. ⋯ AC remains an effective treatment option; the majority of patients tolerate the procedure without issue. Male patients have lower rates of surgical failure, whereas remifentanil administration may increase failure rate.

Temporal bone tegmen defects may be associated with cerebrospinal fluid (CSF) otorrhea. A variety of techniques have been used for repair. We report our experience with skull base reconstruction for tegmen defects using either autologous or alloplastic grafts. ⋯ CSF otorrhea due to tegmen defects can be repaired via a middle fossa craniotomy using either an autologous or alloplastic graft with equivalent outcomes and efficacy, although alloplastic graft helps reduce operating time.
