Can a visible, 1" mucocele (no redness noted) exist where the orbital fat is, the inner, upper part of the orbit and just under the eyebrow?

Usually w/ trauma. Mucoceles may occur spontaneously but in the region of the frontal sinus they are more comminly related to a history of frontal sinus trauma/fracture.
Mucocele. It may be some fat deposit in the area. But mucocele may also occur in this area even though it is not too common.
