Kiesselbachféle
Kiesselbach's plexus, also known as the locus Kiesselbachi or Little's area, is a vascular area located in the anterior nasal septum. It is a common site for nosebleeds, medically termed epistaxis. This area is formed by the anastomosis, or joining, of several blood vessels. These include the anterior ethmoidal artery, the greater palatine artery, the superior labial artery, and branches of the sphenopalatine artery. The rich vascularity and the thinness of the mucosa overlying the Kiesselbach's plexus make it particularly susceptible to trauma and dryness, leading to bleeding. Factors such as dry air, nose picking, forceful nose blowing, and certain medications can contribute to epistaxis from this region. While most nosebleeds originating from Kiesselbach's plexus are minor and can be managed with simple first aid, recurrent or severe bleeding may require medical attention. Diagnosis typically involves a visual inspection of the nasal cavity, often aided by rhinoscopy. Treatment strategies vary depending on the severity and frequency of the bleeding, ranging from conservative measures like nasal saline sprays and humidifiers to more invasive procedures such as cauterization or nasal packing.
