Mucoceles can appear at any site of the oral mucosa containing
salivary glands (11). The two types of mucoceles
are more commonly found at different sites. Extravasation
mucoceles appear frequently on the lower lip whereas
retention mucoceles appear at any other location of
the oral cavity. The lower lip is the most frequent site for
a mucocele as it is the most probable place for a trauma,
especially at premolar level. A study of 312 patients
showed 230 lesions on the lower lip (73.7%), with the
tongue as the second most common location (15.4%)
(9).
