In brief: The difference is

A "maxillary cyst" likely refers to a maxillary retention cyst arising.
Domeshape, from the floor of the maxillary sinus. Benign, asymptomatic, usually self limited, requiring not treatment. A "sinus polyp" is likely related to nasal polyps. Usually the "sinus polyp" is accompanied by other polyps of the nose or ethmoid sinuses. Nasal polyps include nasal congestion, sinusitis, decreased smell.
