Context: Treatment of Stage II Paranasal Sinus and Nasal Cavity Cancer

Ethmoid sinus tumors are usually extensive when diagnosed.[1-3]

Source links and citations

Treatment options for stage II ethmoid sinus tumors include the following:

External-beam radiation therapy alone is generally used and produces better overall results than surgery.

Well-localized lesions can be resected, but resection of the ethmoids, maxilla, and orbit, often with a combined neurosurgical sinus craniofacial approach, is generally required.

If surgery can be done with good functional and cosmetic results, postoperative radiation therapy should be given, even when surgical margins are clear.
