Abstract
Endoscopic sinus surgery has become widely accepted as the standard of treatment for chronic inflammatory diseases of the paranasal sinuses unresponsive to medical treatment. With increased skill with endoscopic surgical technique, advanced technologies such as intraoperative imaging systems, and a better understanding of the complex anatomy of the paranasal sinuses and surrounding vital structures, many otolaryngologists have increasingly applied their expertise in endoscopic sinus surgery to the resection of nasal and sinus neoplasms. The following represents a review of the recent literature on the latest trends regarding endoscopic resection of nasal and paranasal sinus neoplasms.
There has been an increasing popularity in the removal of nasal and paranasal sinus neoplasms through an endoscopic approach. In the recent literature, emphasis has been on the endoscopic surgery of benign tumors, especially inverted papilloma and nasopharyngeal angiofibroma. Other benign neoplasms have also been reported, but only in small case reports. There have been a few recent reports supporting endoscopic removal of malignant neoplasms as well. However, the follow-up is too short and study groups too small to make definitive conclusions.
In the hand of experienced and skilled surgeons, complete endoscopic removal is attainable in most cases. Especially for the more common benign neoplasms, such as inverted papilloma and early stage angiofibroma. En bloc resection is not necessary to achieve oncologic cure. However, several factors have to be considered before selection of this surgical approach. Large tumor size, intracranial or orbital extension, and extensive frontal or infratemporal fossa involvement are relative, but not absolute limitations.
