Endoscopy - An Advancement in Sinus and Skull Base Surgery

Skull base and sinus surgery has evolved dramatically throughout the past century. It is not long ago that the maxillary sinus would principally be reached via an anterior ap‐ proach through the gingivobuccal sulcus of the oral cavity. The earliest days of endos‐ copy date back to the early 1900s, when Hirschmann used a modified cystoscope to examine the sinuses. Thereafter, modern endoscopy has seen advances not only in the types of endoscopes available, but also the types of interventions amenable to the endo‐ scopic approach.
