Ninety percent of nosebleeds (epistaxis) occur in Kiesselbach's plexus, whereas five to ten percent originate from Woodruff's plexus. [3] It is exposed to the drying effect of inhaled air. [3] It can also be damaged by trauma from a finger nail (nose picking), as it is fragile. [3] [4] It is the usual site for nosebleeds in children and young ...
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 ]
Nasopharyngeal angiofibroma is an angiofibroma also known as juvenile nasal angiofibroma, fibromatous hamartoma, and angiofibromatous hamartoma of the nasal cavity. [3] It is a benign but locally aggressive vascular tumor of the nasopharynx that arises from the superior margin of the sphenopalatine foramen and grows in the back of the nasal cavity.
A nosebleed (epistaxis) usually occurs in the anterior part of the nose from an area known as Kiesselbach's plexus which consists of arteries. Woodruff's plexus is a venous plexus in the posterior part and a nosebleed here accounts for only between 5 and 10 per cent of nosebleeds. Older adults are most often affected. [5]
The exact cause of adenoid hypertrophy in children remains unclear, but it is likely linked to immunological responses, hormonal factors, or genetic components. Adenoid hypertrophy is an immunological abnormality characterized by altered cytokine production, with children experiencing higher levels of proinflammatory cytokines.
The true cause of nasal polyps is unknown, but they are thought to be due to recurrent infection or inflammation. [2] Polyps arise from the lining of the sinuses. Nasal mucosa, particularly in the region of middle meatus becomes swollen due to collection of extracellular fluid. This extracellular fluid collection causes polyp formation and ...
In most cases of sinus barotrauma, localized pain to the frontal area is the predominant symptom. This is due to pain originating from the frontal sinus, it being above the brow bones. Less common is pain referred to the temporal, occipital, or retrobulbar region. Epistaxis or serosanguineous secretion from the nose may occur.
A nasal septum perforation is a medical condition in which the nasal septum, the bony/cartilaginous wall dividing the nasal cavities, develops a hole or fissure. [1]This may be brought on directly, as in the case of nasal piercings, or indirectly, as by long-term topical drug application, including nasal administration of ethylphenidate, methamphetamine, cocaine, crushed prescription pills, or ...
