Reconstruction after open surgery for skull-base malignancies

Purpose: Resection of skull base malignancies that would have been associated with unacceptable morbidity and mortality in the past are now performed with reliable results due in large part to advancements in reconstructive surgery. The goal of this review is to describe the best evidence-based methods of reconstruction following open surgery for skull base tumors in order to attain improved outcomes for patients. Methods: A review of recent studies involving reconstruction following open skull base surgeries was performed. Results: Free flaps are now the most commonly recommended method for reconstruction following open skull base surgery, although pedicled regional flaps such as the temporalis muscle, supraclavicular, and submental flaps may be good alternatives in specific cases. Recent series suggest high reconstructive free flap survival rates and low levels of recipient site complications, including neurosurgical complications such as cerebrospinal fluid leak. The location of the resection defect predicts the reconstructive challenges and guides pedicled and free flap selection. Conclusion: Refinements in flap selection and reconstructive technique continue to improve patient outcomes and decrease complication rates following open surgery for skull base malignancies.
