They are a relatively common complication following surgery to the salivary glands, commonly parotidectomy (removal of the parotid gland). (wikipedia.org)
The parotids produce the most fluid saliva, as they are composed of serous acini, with the sublingual gland producing mucus from mucous acini. (medscape.com)
The source of mucin content in ranulas is usually the sublingual gland (also occasionally from the submandibular gland duct). (msdmanuals.com)

Occur3
[ 7 ] age-related decline in saliva output was found to occur in the stimulated parotid, unstimulated submandibular/sublingual, and stimulated submandibular/sublingual glands. (medscape.com)
7] For example, in a cross-sectional, population-based cohort study of 1130 subjects by Dodds et al (2005),[7] age-related decline in saliva output was found to occur in the stimulated parotid, unstimulated submandibular/sublingual, and stimulated submandibular/sublingual glands. (medscape.com)
Ranulas are mucoceles that occur in the floor of the mouth (generally larger than mucoceles that occur elsewhere in the oral cavity). (msdmanuals.com)
Generally1
It was generally believed that parotid flow rates were age-stable in healthy people. (medscape.com)
Sialocele1
In this case the sialocele is the result of saliva draining out of remaining parotid tissue, and occurs about 5 to 10% of cases of superficial (partial) parotidectomy. (wikipedia.org)
Submandibular1
[ 7 ] age-related decline in saliva output was found to occur in the stimulated parotid, unstimulated submandibular/sublingual, and stimulated submandibular/sublingual glands. (medscape.com)
Tumor1
Can ultrasound in combination with virtual touch imaging quantification predict the dignity of a parotid tumor? (uni-augsburg.de)
Benign2
Mucoceles are benign, mucus-filled extravasation pseudocysts that commonly arise on the lower lip of children and young adults. (nih.gov)
This photo shows a labial mucocele, a benign mass consisting of a swollen sac filled with mucus. (msdmanuals.com)
Mouth4
Ranula - is a mucocele found on the floor of the mouth (below the tongue). (studiodentaire.com)
They produce 20 % of the total saliva in the mouth, and the secretion is made through the parotid duct (also called Stensen duct), of which the exit is around the second upper molar. (studiodentaire.com)

Ranulas are mucoceles that occur in the floor of the mouth (generally larger than mucoceles that occur elsewhere in the oral cavity). (msdmanuals.com)
Salivary glands1
Parotid glands are the largest of the major salivary glands. (studiodentaire.com)
Duct2
Traumatic sialoceles commonly arise from injury to the parotid duct. (nih.gov)
Treatment of sialoceles from acute parotid duct injury and for delayed presentations after injury are discussed. (nih.gov)
Oral1
At rest, the parotid glands, located anterior to the ears, produce approximately 25% of oral saliva. (medscape.com)
