Answer

Most mucoceles occur in young individuals, with 70% of individuals being younger than 20 years. The peak prevalence occurs in persons aged 10-20 years. Although not well studied, superficial mucoceles tend to occur in individuals older than 30 years.

Ranulas usually occur in children and young adults, with the peak frequency in the second decade. The cervical variant tends to occur a little later in the third decade.

Mucus retention cysts occur in older individuals; the peak prevalence occurs in persons aged 50-60 years.

Rarely, prenatally diagnosed and congenital mucoceles and ranulas have been reported.
