Cystic fibrosis (CF) is the most common cause of nasal polyps in children. Therefore, any child under 12 to 20 years old with nasal polyps should be tested for CF. [7] [10] Half of people with CF will experience extensive polyps leading to nasal obstruction and requiring aggressive management. [7]
A nosebleed, also known as epistaxis, is an instance of bleeding from the nose. [1] Blood can flow down into the stomach, and cause nausea and vomiting. [8] In more severe cases, blood may come out of both nostrils. [9] Rarely, bleeding may be so significant that low blood pressure occurs. [1]
Normally, the sinuses drain into the nasal cavity through small ostia, which permit mucociliary clearance and ventilation that equilibrates pressure. However, when the opening is obstructed due to inflammation, polyps, mucosal thickening, anatomical abnormalities, or other lesions, pressure equilibration is impossible.
At a basic level, blowing your nose ineffectively raises the odds you’ll continue to have nasal congestion and discomfort. Nose bleed. But blowing your nose too hard can trigger nosebleeds, Dr ...
The exact mechanism for the formation of hematoma from nasal trauma is controversial, but thought to occur in nasal septal hematomas when there is forced to the nasal cartilage. The force causes the perichondrial blood vessels to leak and rupture in the nasal septum. [7] The cartilage in the septum is avascular and can be 2–4 mm thick.
They may cause pressure necrosis of the nasal septum or lateral wall of nose. Rhinoliths can cause nasal obstruction, epistaxis, headache, sinusitis and epiphora. They can be diagnosed from the history with unilateral foul-smelling blood-stained nasal discharge or by anterior rhinoscopy. On probing, the probe can be passed around all its corners.
A polyp is an abnormal growth of tissue projecting from a mucous membrane. If it is attached to the surface by a narrow elongated stalk, it is said to be pedunculated; if it is attached without a stalk, it is said to be sessile. Polyps are commonly found in the colon, stomach, nose, ear, sinus(es), urinary bladder, and uterus.
When polyps are present, the condition is called chronic hyperplastic sinusitis; however, the causes are poorly understood. [28] It may develop with anatomic derangements, including deviation of the nasal septum and the presence of concha bullosa (pneumatization of the middle concha) that inhibit the outflow of mucus, or with allergic rhinitis ...
