Nasal septal hematoma is a condition affecting the nasal septum. [1] It can be associated with trauma. [2] A septal hematoma is blood that collects in the space between the septal cartilage and the overlying perichondrium (a cross section of the cartilaginous portion of the nasal septum). A hematoma may deprive the septal cartilage of its blood ...
The ala of the nose (ala nasi, "wing of the nose"; plural alae) is the lower lateral surface of the external nose, shaped by the alar cartilage and covered in dense connective tissue. [1] The alae flare out to form a rounded eminence around the nostril. [17] Sexual dimorphism is evident in the larger nose of the male.
Relapsing polychondritis is a systemic disease characterized by repeated episodes of inflammation and in some cases deterioration of cartilage. The disease can be life-threatening if the respiratory tract, heart valves, or blood vessels are affected. The exact mechanism is poorly understood.
The nasal septum contains bone and hyaline cartilage. [3] It is normally about 2 mm thick. [4] The nasal septum is composed of four structures: Maxillary bone (the crest) Perpendicular plate of ethmoid bone. Septal nasal cartilage (ie, quandrangular cartilage) Vomer bone. The lowest part of the septum is a narrow strip of bone that projects ...
In anatomy, a nasal concha (/ ˈkɒnkə /; pl.: conchae; / ˈkɒnkiː /; Latin for 'shell'), also called a nasal turbinate or turbinal, [1][2] is a long, narrow, curled shelf of bone that protrudes into the breathing passage of the nose in humans and various other animals. The conchae are shaped like an elongated seashell, which gave them their ...
The nasal cartilages are structures within the nose that provide form and support to the nasal cavity. [1] The nasal cartilages are made up of a flexible material called hyaline cartilage (packed collagen) in the distal portion of the nose. [2] There are five individual cartilages that make up the nasal cavity: septal nasal cartilage, lateral ...
The septal nasal cartilage ( cartilage of the septum or quadrangular cartilage) is composed of hyaline cartilage. [ 1] It is somewhat quadrilateral in form, thicker at its margins than at its center, and completes the separation between the nasal cavities in front. Its anterior margin, thickest above, is connected with the nasal bones, and is ...
Prognosis. Generally good [5] Frequency. Common [4] A nasal fracture, commonly referred to as a broken nose, is a fracture of one of the bones of the nose. [3] Symptoms may include bleeding, swelling, bruising, and an inability to breathe through the nose. [1][3] They may be complicated by other facial fractures or a septal hematoma. [1]
