Endoscopic Management of Maxillary Sinus Diseases of Dentoalveolar Origin.

Endoscopic surgery on the maxillary sinus has experienced significant advances in technique and approaches since the maxillary antrostomy was introduced in the 1980s. Disease processes that previously required open surgical approaches to the maxillary sinus can now be treated endoscopically while preserving form and function of the sinus and without injuring the maxillary sinus mucosa or disrupting normal mucociliary clearance. Understanding the techniques described in this article will allow surgeons to appropriately plan treatment strategies for patients with a variety of maxillary sinus diseases from dentoalveolar origin.
