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.

These cysts usually appear as rounded dome shaped soft tissue masses most often on the floor of the maxillary sinus. These cavities are called sinuses and they are located in the maxilla or upper jaw. Mucous retention cysts can appear in the maxillary sinus area from repeated sinus infections. 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. As there is no normal tissues regeneration and the excretory ducts patency of the mucous glands is not restored. But if there is an infection of the mucous retention cyst there can be a pain in the face near the cheekbones. The mucous retention cyst in the maxillary sinus is generally painless.

A maxillary sinus cyst is an abnormal tissue growth located in either of the cavities located behind the cheekbones on either side of the nose. Within the maxillary sinus which lies beneath the cheek bone on each side are mucous glands. They are usually found when an x ray or scan is done of the sinuses. The collection of extravasated fluid develops a fibrous wall around itself forming a pseudocyst.

The lesion is a result of the extravasation of saliva from an injured minor salivary gland. A mucocele or mucous retention cyst is a benign pathologic lesion. The disease appears in the form of a small vessel with thin walls that have spherical capacity. 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.

The cyst does not usually cause any symptoms and does not damage expand or thin the wall of the sinus. Often their formation is due to chronic diseases. The aim of this study was to investigate the long term natural course of retention cysts of the maxillary sinus. Symptoms are usually non existent but in some cases include chronic sinus infections dizziness headaches and facial pain.

Types of mucous retention cyst the types of mucous retention cysts are divided into the regions they are found. Size and location are always different as well as the symptoms. 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 lesion can fluctuate in size depending on its fluid filled state. Maxillary sinus retention cysts are most often the result of inflammatory changes in the mucous membranes.
