Endoscopic management of sinonasal malignancy.

The advent of rigid telescopes has revolutionized the management of rhinologic disease. These instruments have been used as a diagnostic and therapeutic tool for paranasal sinus inflammatory diseases since the 1970s. Endoscopic techniques have been used for treating increasingly complex intranasal pathology, including nasolacrimal duct obstruction, cerebrospinal fluid leaks/encephaloceles, dysthyroid orbitopathy, and optic neuropathy. Recently, endoscopic techniques have also been used successfully to manage selected tumors, including inverted papilloma, angiofibromas, and hypophyseal tumors. This article reviews patient evaluation strategies, surgical techniques, and outcomes data for the minimally invasive endoscopic resection.
