Pharyngeal scar stenosis

Introduction to pharyngeal scar stenosis For soft palate, the scar adhesion between the posterior pharyngeal wall of the pharyngeal arch makes the normal passage between the nasopharynx and the oropharynx smaller, narrow or locked. The nasopharyngeal stenosis is often caused by scar tissue, and the patient has basic anatomy. For trauma, corrosion, special infections such as syphilis, leprosy, induration and other diseases, when performing adenoidectomy, excessive mucosal damage, scarring can also occur, congenital is rare. Nasopharyngeal atresia is mostly congenital dysplasia, often accompanied by posterior nostril atresia, and acquired are rare. The cause of the disease is often caused by scar tissue. The patient has basic anatomical structure, often caused by trauma, corrosion, special infections such as syphilis, leprosy, induration, etc. When performing adenoidectomy, excessive mucosal damage Scarring stenosis can also occur, and congenital is rare. basic knowledge The proportion of illness: 0.006%-0.009% Susceptible people: no specific population Mode of infection: non-infectious Complications: otitis media

Causes of pharyngeal scar stenosis

Often caused by scar tissue, the patient has a basic anatomical structure, often caused by trauma, corrosion, special infections such as syphilis, leprosy, induration, etc., when performing adenoidectomy, excessive mucosal damage can also occur Scarred stenosis, congenital is rare.

Pharyngeal scar stenosis prevention

Prevent oropharyngeal trauma.

Pharyngeal scar stenosis Complications otitis media

In severe cases, there may be nasal congestion, loss of olfactory or disappearance, snoring, mouth breathing, occlusive nasal sounds or ambiguous pronunciation.

Symptoms of pharyngeal scar stenosis Common symptoms Nasal snoring, hearing loss, mouth breathing

Depending on the degree of stenosis, the light can be asymptomatic, the severe one can have nasal congestion, the sense of smell is reduced or disappeared, snoring, mouth breathing, occlusive nasal sound or pronounced ambiguity, nasal secretions often remain in the nasal cavity, not easy to sputum, The eustachian tube is affected by hearing loss or concurrent otitis media.

Check: Zhangkou sees the adhesion between the soft palate and the posterior wall of the pharynx. The uvula often disappears. There is often a small passage leading to the nasopharynx. The curved probe is inserted into the opening for exploration to understand the size and scar of the passage. In the case of upward expansion, the finger can be used to detect the extent of adhesion and the thickness of the scar. The nasal cavity has more secretions. A little cotton in the front nostril can detect the presence or absence of channels in the nasopharynx, such as the soft palate and the posterior pharyngeal wall. There are small holes between them, you can indirectly nasopharyngoscopy to understand the extent and extent of nasopharyngeal scar adhesion.

Lateral soft tissue or intranasal lipiodol angiography is of great help in diagnosis and treatment.

Examination of pharyngeal scar stenosis

The mouth of the mouth sees the adhesion between the soft palate and the posterior pharyngeal wall. The uvula often disappears. There is often a small passage leading to the nasopharynx. The curved probe is inserted into the opening for exploration to understand the size of the channel and the scar extension. In the case, using a finger to touch from the mouth can roughly find out the extent of adhesion and the thickness of the scar, the nasal cavity has more secretions, and a small amount of cotton in the front nostril can detect the presence or absence of channels in the nasopharynx, such as between the soft palate and the posterior pharyngeal wall. There are small holes, you can indirect nasopharyngoscopy to understand the extent and extent of nasopharyngeal scar adhesion.

Lateral soft tissue or intranasal lipiodol angiography is of great help in diagnosis and treatment.

Diagnosis and diagnosis of pharyngeal scar stenosis

The disease can be diagnosed based on clinical symptoms and examinations without identification.
