What's the difference between mucocele and protrusion?

Mucocele


Definition:

  • (n.) An enlargement or protrusion of the mucous membrane of the lachrymal passages, or dropsy of the lachrymal sac, dependent upon catarrhal inflammation of the latter.

Protrusion


Definition:

  • (n.) The act of protruding or thrusting forward, or beyond the usual limit.
