摘要

Anterior skull base (ASB) defects present a significant challenge in head and neck reconstructive surgery. The main goal of skull base reconstruction is to create a watertight separation between the intracranial cavity and aerodigestive tract. Successful reconstruction aims to prevent cerebrospinal fluid (CSF) leak, pneumocephalus, and a range of infectious manifestations. Functional outcomes and cosmesis are also critical considerations when developing a reconstructive plan. Advancements with endoscopic endonasal approaches have revolutionized skull base surgery but also have created new reconstructive challenges due to the narrow operative corridor, especially for extensive defects or salvage cases where microvascular free tissue transfer is required. Though a variety of techniques including local, regional, and free flaps have been described, ASB reconstruction remains a difficult undertaking due to the complex anatomy and high risk for post-operative complications. This review provides a comprehensive discussion of available reconstructive techniques that can be used after both open and endoscopic ASB resections to help determine the optimal reconstruction for a variety of defects.
