The indications for surgery for localized cysts of the sieve sinus are often judged on the basis of symptoms, which mainly include ocular symptoms, facial symptoms, nasal symptoms and brain symptoms.
1. Ocular symptoms: sial sinus cysts can cause displacement of the eyeball, tearing, diplopia, headache and eye pain after invading the orbit. The posterior group of sieve sinus is close to the optic nerve foramen and supraorbital fissure, the cyst compression can cause eyeball protrusion, and can compress the orbital cusp and lead to blindness, paralysis of ocular muscles, ocular sensory disorders, and pain, and so on, and those who have the orbital cusp syndrome are all the indications for the surgery.
2. Facial symptoms: the sieve sinus cyst increases in size, which can lead to bulging at the inner canthus. The smooth surface of the mass can be touched by palpation, like the feeling of pressing a ping-pong ball or breaking an eggshell; if the bone has been destroyed, the edge of the defective bone can be touched, and the mass can be touched and it is very soft and elastic. This situation is in line with the indications for surgery.
3. Nasal symptoms: compression of the cyst from the elevation of the face, occasionally see the liquid from the nasal cavity. The cysts can also collapse on their own many times, and repeated intermittent nasal spillage. Sieve sinus cysts may protrude into the middle nasal tract, making the middle nasal tract bulge or sieve bubble become larger. When the cysts are large, there may be nasal congestion, runny nose, loss of smell and other symptoms, and the cysts can be surgically removed.
4. Brain symptoms: when the cyst increases in size and compresses the nearby cerebral nerves, pain or numbness in the back of the eyes, around the eyes, or in the cheeks of varying degrees of severity may occur. If the cyst becomes infected and forms a pus cyst, there may be fever, generalized discomfort, headache, etc. It may also lead to serious intraorbital and intracranial complications. Surgery is also indicated at this time.
When a localized cyst in the sieve sinus is detected, complete the relevant examinations and follow the doctor’s advice to choose surgical treatment.
