Posterior nostril polyps
Introduction
Introduction to the polyp behind the maxillary sinus The polyposis of the posterior maxillary sinus is a polyp that originates in the maxillary sinus and has a slender stalk and a posterior protrusion to the nostril. This polyp has its own pathological and clinical features, which are generally thought to be another polyp lesion that is different from normal nasal polyps. The disease is mostly caused by adolescents, and there is no difference in the incidence of men and women. basic knowledge The proportion of illness: 0.001% Susceptible people: no specific population Mode of infection: non-infectious complication:
Cause
Causes of polyp behind the maxillary sinus
The cause is not clear, the polyp origin occurs in the maxillary sinus, and then enters the nasal cavity through the maxillary sinus through the maxillary sinus at the sinus ostium of the middle nasal passage, and then slides backward to the posterior nostril and can protrude into the nasopharynx.
Prevention
Prevention of polyp behind the maxillary sinus
There is no effective preventive measure for this disease. Early diagnosis and early treatment are the key to the prevention and treatment of this disease.
Complication
Complications of the posterior nasal sinus polyp Complication
If the polyp protrudes into the nasopharyngeal cavity and continues to increase, it can produce bilateral nasal congestion. The large volume can fall into the throat and cause foreign body sensation.
Symptom
Post-maximal sinus nostril polyp symptoms Common symptoms Nasal discharge nasal congestion Nasopharyngeal foreign body Turbinate swelling
Pre-menstrual, posterior nasal examination and combined medical history, easy to diagnose, but for juvenile patients should pay attention to the identification of nasopharynx fibrous angiomas, the latter texture is hard, for this identification can not take a pathological biopsy.
The cause is not clear, the polyp origin occurs in the maxillary sinus, and then enters the nasal cavity through the maxillary sinus in the sinus ostium of the middle nasal passage, and then slides backwards into the posterior nostril and can protrude into the nasopharynx. Stammberger (1986) uses the intranasal sinus. Speculoscopy revealed that polyps originated from the upper anterior horn of the sinus ostium in the maxillary sinus. Kamel (1990) used endoscopy to find 13 cases of posterior maxillary sinus in 22 cases of posterior nostril polyps, and 9 cases due to sinus It is difficult to determine the origin of the wall mucosa. Berg (1988) found that the polyp was connected with the sinus cyst in the sinus cavity by 15 cases of posterior nostril nasal maxillary sinus exploration. Therefore, he believed that the posterior nostril polyps originated from the maxillary sinus cyst, cyst. Gradually increase the transsacral sinus into the nasal cavity, and finally form the nasal nostrils. Histological examination revealed that there are often more mucous acinus in the polyp tissue, and some form a large cyst. The cell infiltration is mainly a small amount of plasma cell infiltration, rarely There is infiltration of eosinophils.
The clinical features of posterior nostril polyps are single, so unilateral progressive nasal congestion is the main symptom. The patient first feels that there is something in the nose with the breathing activity, and the inhalation is still pleasant and the exhalation is not smooth, such as polyps protruding into the nose. The pharyngeal cavity continues to increase, which can produce bilateral nasal congestion. The large volume can fall into the throat and cause foreign body sensation.
Examine
Examination of the polyp behind the maxillary sinus
The front nose is often seen with a grayish white smooth stalk extending backwards. If the turbinate is fully contracted with ephedrine cotton, the stalk can be seen from the middle nasal passage, the touch is soft and can be moved, and the posterior endoscope can be seen. The polyp is translucent, pale red or grayish white, located in the posterior nostril or nasopharynx, and the polyps that fall into the pharynx are easier to see when lifted on the soft palate.
X-ray examination showed that the maxillary sinus mucosa was thickened and there was a small semicircular cyst shadow.

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

Identification with general nasal polyps.
