Mucus Retention Cyst Floor Maxillary Sinus

Cysts are closed pocket like formations of tissue and are filled with liquid air or semi solid material.

Mucus retention cyst floor maxillary sinus.

Mucous retention cysts can appear in the maxillary sinus area from repeated sinus infections. A blockage in the mucous duct can cause the gland to enlarge which can lead to the formation of a dome shaped maxillary mucous retention cyst. They are usually found when an x ray or scan is done of the sinuses. Within the maxillary sinus which lies beneath the cheek bone on each side are mucous glands.

According to statistics every 10 th person has this disease. A few cases may see facial pain headaches and sinus infections. A mucous retention cyst in the maxillary sinus area usually does not show any symptoms. The collection of extravasated fluid develops a fibrous wall around itself forming a pseudocyst.

A mucocele or mucous retention cyst is a benign pathologic lesion. The lesion can fluctuate in size depending on its fluid filled state. These cysts usually appear as rounded dome shaped soft tissue masses most often on the floor of the maxillary sinus. Often their formation is due to chronic diseases.

Types of mucous retention cyst the types of mucous retention cysts are divided into the regions they are found. The aim of this study was to investigate the long term natural course of retention cysts of the maxillary sinus. Maxillary sinus retention cysts are most often the result of inflammatory changes in the mucous membranes. So they are accidentally discovered on radiological tests like ct scan of the paranasal sinuses and opg x ray which is done for knowing the condition of the teeth.

As there is no normal tissues regeneration and the excretory ducts patency of the mucous glands is not restored. They are slow growing lesions but mucosal and cortical integrity is preserved. The disease appears in the form of a small vessel with thin walls that have spherical capacity. The lesion is a result of the extravasation of saliva from an injured minor salivary gland.

Symptoms are usually non existent but in some cases include chronic sinus infections dizziness headaches and facial pain. The cyst does not usually cause any symptoms and does not damage expand or thin the wall of the sinus. The mucous retention cyst in the maxillary sinus is generally painless. Retention cysts are seen on imaging as rounded dome shaped lesions often situated on the maxillary sinus floor.

Cyst in the maxillary sinus is a common benign disease. Size and location are always different as well as the symptoms.
