What are the causes and clinical symptoms of sinusitis cysts?

Sinus cyst is a type of rhinitis. Many people do not know much about sinus cysts and ignore their severity, which leads to serious harm. So what is the cause of sinus cysts? What are the symptoms?

Causes of Sinus Cysts

1. According to the causes, it can be divided into congenital blindness, glandular retention due to glandular duct obstruction and stimulation by inflammatory infection factors, etc.

2. There are various facial cleft cysts due to congenital genetic or developmental abnormalities, most of which are developed from the embryonic remnants of the facial processes at the point where they are connected or fused during development.

3. Cysts caused by infection and stimulation are caused by cystic changes in the apical granulation tissue after tooth root infection or damage. Sinus mucocele can also be caused by trauma.

Symptoms of sinus cysts

1. External deformity: The surface of the sinuses is bulging, and the subcutaneous part feels smooth and ping-pong-like.

2. Eye symptoms: eye pain, diplopia, epiphora, and eye displacement.

3. Nasal examination: The lateral wall of the nasal cavity is displaced toward the midline.

4. There are dead teeth or caries, mostly on the lateral incisors. Missing teeth or having underdeveloped deciduous teeth.

5. Complications of infection may cause general discomfort, fever, headache, local redness, swelling and pain.

Examination of sinus cysts

1. The general sinus cyst examination project is mainly based on the examination box "A".

2. Special examinations for odontogenic cysts or tumors may include "A", "B" and "C". Sinus mucocele is caused by obstruction of the sinus opening, and mucosal cyst is caused by obstruction of the glands in the sinus. Therefore, preventing upper respiratory tract infections, paying attention to allergic factors, promptly treating rhinitis and sinusitis, and keeping the nasal cavity unobstructed are the keys to preventing the disease. Early examination, detection and treatment of diseased teeth can prevent the occurrence of odontogenic cysts. The disease is treated by complete removal of the cyst via intranasal or extranasal approach to establish unobstructed sinus and nasal drainage. For cases of odontogenic origin, the diseased teeth need to be removed to achieve a radical cure.

Diagnosis of sinus cysts

Diagnosis

1. The surface of the sinuses is bulging, and the subcutaneous layer feels smooth and like a ping-pong ball.

2. Eye pain, diplopia, epiphora, and eye displacement.

3. The lateral wall of the nasal cavity shifts toward the midline.

4. Dead teeth or caries are more common in lateral incisors, missing teeth or underdeveloped deciduous teeth.

5. Sinus puncture to extract mucus or pus.

6. X-ray films show that the sinus cavity of mucocele is enlarged, the sinus wall is thinned or disappeared, the edge of the cyst shadow is smooth, and the density is uniform. Mucosal cysts are localized semicircular shadows with clear boundaries in the maxillary sinus. The sinus of an odontogenic cyst contains bone resorption and cystic shadows of the tooth or root.

Treatment of sinus cysts

Treatment principles

1. Mucocele: Remove the cyst through the intranasal or extranasal route, and the drainage port must be unobstructed.

2. Mucosal cysts generally do not require surgery. If the symptoms are obvious and recurring, radical maxillary sinus surgery can be performed to remove them.

3. For dental cyst, maxillary sinus cleaning is performed to remove the cyst and preserve the maxillary sinus mucosa. For tooth root cysts, the cyst is removed and the affected tooth is treated.

Medication principles

1. The disease is mainly treated by surgical removal of the cyst and establishment of unobstructed drainage.

2. Odontogenic cysts still require removal of the diseased teeth.

3. To control infection before and after surgery, antibiotics and other auxiliary drugs can be used.
