Skull base reconstruction.

Reconstruction of skull base defects following tumor resection is of paramount importance in avoiding serious and life-threatening complications. Cranial base surgery has evolved and outcomes have steadily improved as increasingly reliable reconstructive techniques have been adapted to repair the challenging wounds in this complex anatomic region. The most significant development has been the introduction and refinement of microvascular free tissue transfer to the skull base over the past 15 to 20 years.

Orbital preservation in surgical management of sinonasal malignancy.

Objective: To determine the oncological and functional outcome when applying defined criteria for orbital preservation during surgical treatment of sinonasal malignancy encroaching on the orbital structures.

Study Design: Retrospective consecutive review of patients in tertiary care center setting.

Methods: Analysis of 66 patients undergoing surgical treatment for sinonasal malignancy encroaching on the orbit.
