Is the word 'Dean' has ever used in the Eastern Orthodox Church (either from Canonical or Non-canonical)? edit

I have undoing a edit war by the same user, who is suggesting to delete this page again with a unintentional semi-irrational thinking by not discussing here was definitely mistake.

But, the question is the word 'Dean' is unironically used predominantly by the Catholic, Anglican/Episcopal, and sometimes Lutheran Churches, but not all by mainstream Christian denominations, including the Eastern Orthodox Church too. Where I can't find any reference of being used by all Canonical or Non-Canonical Orthodox Churches. But according to this user Leefeni de Karik a self-proclaimed Portuguese Orthodox follower, keep claim the Dean is being used by the Semi-Orthodox Autonomous Church, Russian Orthodox Church Outside of Russia to described this Church as?
