Retention cyst on the lower lip – one of the most common pathologies of the oral mucosa. It is a benign neoplasm that occurs as a result of blockage of the duct of the minor salivary gland. The reason for this may be an injury to the lower lip (biting, blow, burn) or inflammatory processes. In rare cases, the disease may be associated with atrophy of the excretory streams of the minor salivary glands.
Symptoms of the retention cyst of the lower lip
The retention cyst is a connective tissue capsule with contents that looks like a rounded formation, a ball protruding from the inside of the lip. This formation is painless, but still causes some discomfort. The cyst is prone to rapid growth, can reach two centimeters in diameter. As a rule, the mucous membrane above it does not undergo changes, but in some cases it may acquire a bluish tint due to the accumulation of contents.
The cyst contains a viscous, almost clear fluid that resembles stagnant saliva. On palpation, the formation is soft, moves freely. Sometimes during a meal, the capsule is damaged and emptied, but after that the cyst is filled again. Most often, the retention cyst is single-chamber, although there are cases of the formation of multi-chamber cysts on the lower lip. A cyst on the lower lip makes it difficult to eat, interferes with normal conversation.
Treatment of the retention cyst of the lower lip
In no case should you try to get rid of such a neoplasm on your own. You should consult a doctor who, in order to make an accurate diagnosis, will prescribe an ultrasound and a puncture with a study of the contents of the cyst. This makes it possible to accurately determine the size and structure of the tumor. In some cases, probing of the channels is also carried out to determine the width of the duct.
Treatment of a retention cyst of the lower lip involves surgical removal of the tumor under local anesthesia. After two incisions are made over the cyst, it is exfoliated. The small salivary glands exposed in the wound are also subject to removal. Next, sutures are applied from a thin kegut and a sterile bandage. After a week, the stitches dissolve. After the operation, the patient is treated at home, performing mouth rinses with antiseptic solutions. Depending on the volume of the operation, full healing can take up to six months or more.
