Nasal mucosa ulcer
Introduction
Introduction Nasal mucosal ulcer refers to nodular infiltration under the nasal mucosa, which in turn can cause scarring adhesions. In the late stage, there was atrophy due to dryness and scarring of the nasal cavity. The anterior nares are narrow. The nasal mucosa is pale and thick, and the secretions increase. There may be purulent sputum and nosebleeds, but the patient may not feel pain.
Cause
Cause
1, nasal mucosa ulcers, erosion. Common in the lower part of the nasal septum, mostly caused by chronic inflammation. Chemical gases, high temperatures, and dry air can all be the cause. In addition, nasal septum or rectangular process, nasal septum perforation, atrophic rhinitis, can also cause local nasal mucosal ulcer formation and lead to bleeding.
2. Acute infection of the nose and sinuses.
3, trauma. Nasal trauma occurs in the nasal mucosa tear, which can cause nosebleeds. The nasal stenosis combined with external injury fractures often complicated with anterior ethmoid rupture, which can cause upper nasal bleeding. Skull base fracture can cause the internal carotid artery to rupture, form a traumatic pseudoaneurysm, and severe nasal discharge occurs through the sphenoid sinus. If the anterior cranial fossa fracture has a ruptured anterior cerebral artery, it can cause bleeding at the level of the ethmoid at the top of the nasal cavity
4. Tumors. Tumor-induced epistaxis is caused by surface ulceration of the tumor itself, and the degree of bleeding varies depending on the nature of the tumor. Fatal nosebleeds can occur when a malignant tumor invades a large blood vessel in the late stage.
Examine
an examination
Related inspection
Nasal endoscopy nasopharynx MRI
Basic inspection:
1. Front nose examination.
2. X-ray films clearly have no sinus infection.
Further examination:
1. Nasal secretion smear to detect pathogenic bacteria.
2. Nasal secretions bacterial culture + drug sensitivity.
3. If necessary, virus inspection requires special cultivation, separation and identification.
Diagnosis
Differential diagnosis
Differential diagnosis of nasal mucosal ulcers:
Nasal mucosal ulcers need to be distinguished from nasal congestion. Nasal congestion is generally caused by foreign body sensation in the nasal cavity, nasal obstruction, poor ventilation, and often because the mucosal edema or mucus is too thick to block the nasopharynx and nasal passages, resulting in narrowing of the nasal passages. Often occurs in rhinitis, sinusitis, nasal tumors and polyps block the nasal respiratory passages.
Patients often have nasal congestion, runny nose, itchy nose, throat discomfort, cough and other symptoms.
