The most common location to find a mucocele is the inner surface of the lower lip. It can also be found on the inner side of the cheek (known as the buccal mucosa), on the anterior ventral tongue, and the floor of the mouth. When found on the floor of the mouth, the mucocele is referred to as a ranula. They are rarely found on the upper lip.
Small defects of the upper and lower lip can be closed primarily. For the upper lip, defects of up to 1/4 (25%) of the lip may be closed primarily. For the lower lip, defects of up to 1/3 of the lip may be closed primarily. This means the edges of the defect are simply sutured together in three layers: oral mucosa, muscle, and skin.
This nasolabial cyst, also known as a nasoalveolar cyst, is located superficially in the soft tissues of the upper lip. Unlike most of the other developmental cysts , the nasolabial cyst is an example of an extraosseous cyst, one that occurs outside of bone.
Minor trauma to the floor of the mouth is thought to damage the delicate ducts that drain saliva from the sublingual gland into the oral cavity. [2] The lesion is a mucous extravasation cyst (mucocele) of the floor of mouth, although a ranula is often larger than other mucoceles (mainly because the overlying mucosa is thicker). [3]
a pit in the upper lip, in which case it may be called a midline sinus of the upper lip, [2] and; pits in the lower lip, in which case it may be called a congenital sinus of the lower lip. [2] In some cases commissural pits have been reported in combination with preauricaluar pits, which are near the ear. [1]
The angel lightly taps the infant's upper lip before birth to prevent the infant from revealing the secrets of the universe; the infant then forgets the Torah it has been taught. [10] Some believers of the story speculate that this is the cause of the philtrum, but it does not have a basis in traditional Jewish texts. [11]
They are painless papules (small bumps), about 1–3 mm in greatest dimension. The most common site is along the line between the vermilion border and the oral mucosa of the upper lip, or on the buccal mucosa (inside the cheeks) in the commissural region, [10] often bilaterally. They may also occur on the mandibular retromolar pad and tonsillar ...
Oral submucous fibrosis (OSF) is a chronic, complex, premalignant (1% transformation risk) condition of the oral cavity, characterized by juxta-epithelial inflammatory reaction and progressive fibrosis of the submucosal tissues (the lamina propria and deeper connective tissues).
