Mucous retention cyst in maxillary sinus indicated by the asymmetrical blue lump to the right of the nose 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 .
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]
Oral mucocele is the most common benign lesion of the salivary glands generally conceded to be of traumatic origin. It is characterized by the pooling of mucus in a cavity due to the rupture of salivary ducts or acini. It can occur in the lower lip, palate, cheeks, tongue and the floor of the mouth.
Vocal fold cysts (also known as vocal cord cysts) are benign masses of the membranous vocal folds. [1] These cysts are enclosed, sac-like structures that are typically of a yellow or white colour. [2] They occur unilaterally on the midpoint of the medial edge of the vocal folds. [1] They can also form on the upper/superior, surface of the vocal ...
For example, mucous cyst of the oral mucosa and nasolabial duct cyst are not of odontogenic origin. In addition, there are several conditions with so-called ( radiographic ) ' pseudocystic appearance' in jaws; ranging from anatomic variants such as Stafne static bone cyst , to the aggressive aneurysmal bone cyst .
The mouth is also subject to sudden changes in temperature and pH meaning it must be able to adapt to change quickly. The mouth is the only place in the body which provides the sensation of taste. Due to these unique physiological features, the oral mucosa must fulfil a number of distinct functions.
The submandibular gland is medial to the angle of the mandible, and it drains its mixture of serous and mucous saliva via the submandibular duct (Wharton duct) into the mouth, usually opening in a punctum in the floor of mouth. The sublingual gland is below the tongue, on the floor of the mouth; it drains its mostly mucous saliva into the mouth ...
Sometimes poorly constructed prosthetic teeth may be the cause if the original bite is altered. Usually, the teeth are placed too far facially (i.e., buccally and/or labially), outside the " neutral zone ", which is the term for the area where the dental arch is usually situated, where lateral forces between the tongue and cheek musculature are ...
