Sinus mucosal cyst

Brief introduction of sinus mucosa cyst The sinus mucosa cyst is blocked by the mucous gland or serous gland of the sinus mucosa, and the gland secretion is expanded to form. Mucosal cysts can occur in any sinus, but mostly in the maxillary sinus, mostly in the maxillary sinus floor and inner wall. The disease is mostly unilateral. It grows very slowly, grows to a certain extent and can naturally rupture, and the sac fluid drains out through the sinus ostium. Often asymptomatic, more inadvertently found in the sinus X-ray examination. There are no obvious symptoms in this disease alone, occasionally the forehead headache or cheek pressure, or the same side of the upper toothache. Occasionally, intermittent yellow liquid can flow out from the nasal cavity. The cyst is asymptomatic and harmless to the human body. When the cyst is large, there is a natural tendency to rupture, so it is generally not advocated. If there are obvious symptoms or the patient's mental stress is too high, it can be surgically removed. If found in maxillary sinus surgery, it should be removed by the way. Nasal endoscopic surgery can be performed by expanding the maxillary sinus ostium. basic knowledge The proportion of sickness: 0.01% Susceptible people: no specific people Mode of infection: non-infectious Complications: brain abscess subdural abscess

Cause of sinus mucosal cyst

Cause:

1, mucosal gland obstruction in the mucosa, glandular endocrine retention and gradually increased, forming a cyst under the mucosa, is a secretory type, also known as mucinous cyst or submucosal cyst, the wall of the mucous gland duct epithelium, cystic fluid is turbid mucus.

2, mucosal inflammation or allergic reaction, the capillary exudation of the capillary is retained in the submucosal connective tissue, gradually expanding to form a cyst, is a non-secretory type, also known as serous cyst, the wall of the sinus mucosa with inflammatory changes, cyst fluid It is a translucent grass yellow or ginger yellow condensable liquid.

Prevention of sinus mucosal cysts

1, prevention of upper respiratory tract infections, pay attention to allergic factors, timely treatment of rhinitis, sinusitis, to maintain nasal patency is the key to prevent the disease.

2, early detection, detection, treatment of sick teeth, can prevent the occurrence of odontogenic cysts.

3, the disease is completely removed by intranasal or extranasal approach cysts, establish sinus nasal cavity drainage. Tooth-derived people still need to remove the diseased teeth and can be cured.

Sinus mucosal cyst complications Complications, brain abscess, subdural abscess

After the mucinous cyst is infected, it becomes a pus cyst. In the sphenoid sinus and frontal sinus cysts, such as sinus wall bone damage absorption, can expand into the skull, easy to be complicated by various intracranial infections (such as epidural abscess, subdural abscess, brain abscess). The frontal sinus cyst, such as self-rupture drainage, can form a frontal sinus with balloon swelling and brain accumulation. There have also been reports of giant sinus mucinous cysts, and cerebrospinal fluid rhinorrhea and cerebral palsy after surgery.

There are no obvious symptoms in this disease alone, occasionally the forehead headache or cheek pressure, or the same side of the upper toothache. Occasionally, intermittent yellow liquid can flow out from the nasal cavity.

Examination of sinus mucosal cysts

Mostly found in the sinus X-ray film examination, or in the maxillary sinus puncture when the yellow liquid is dripping clear, or found in the maxillary sinus surgery and diagnosed. Repeated intermittent intranasal outflow of yellow fluid suggests cysts of the sinus mucosa.

X-ray radiography is extremely important for its diagnosis and localization, especially the sphenoid sinus cyst. X-ray films can show that the diseased sinus is obviously enlarged, the bone wall is absorbed and thinned, and the bulge is rounded with a rounded shadow. The edge is smooth and surrounded by a white line of bone reaction. The sinus wall bone may have loose changes, or pressure absorption, defects, but no invasiveness. Forehead and ethmoid cysts are often seen in the sacral margin and the posterior wall of the frontal sinus. When suspected sphenoid sinus cysts, it is advisable to take lateral radiographs or tomography. CT and MRI clearly show the size, extent and extent of bone destruction.

Diagnosis and differentiation of sinus mucosa cyst

diagnosis

Diagnosis can be based on medical history, clinical symptoms, and laboratory tests.

Differential diagnosis

Different from other cysts.
