Takeaway
In sinonasal mucosal melanoma (SNMM) endoscopic resection is associated with longer overall survival than open resection.
Why this matters
Sinonasal mucosal melanoma (SNMM) is an extremely rare form of melanoma with a 5-year survival rate of <25%.
Established treatment options include wide local excision; recently, endoscopic resection has been trialed, however due to the rarity of the disease data on the benefits of open versus endoscopic resection are lacking.
