Broadly, most nasal bones can be categorized as "V-shaped" or "S-shaped" but these are not scientific or medical categorizations. When viewing anatomical drawings of these bones, consider that they are unlikely to be accurate for a majority of people. [1] The two nasal bones are joined at the midline internasal suture and make up the bridge of ...
The nasal root is above the bridge and below the glabella, forming an indentation known as the nasion at the frontonasal suture where the frontal bone meets the nasal bones. [16] The nasal dorsum also known as the nasal ridge is the border between the root and the tip of the nose, which in profile can be variously shaped. [17]
Nasal septum deviation is the most common cause of nasal obstruction. [7] A history of trauma to the nose is often present including trauma from the process of birth or microfractures. [ 7 ] A medical professional, such as an otorhinolaryngologist (ears, nose, and throat doctor), typically makes the diagnosis after taking a thorough history ...
The floor of the nasal cavities, which also form the roof of the mouth, is made up by the bones of the hard palate: the horizontal plate of the palatine bone posteriorly and the palatine process of the maxilla anteriorly. The most anterior part of the nasal cavity is the nasal vestibule. [4]
The fleshy external end of the nasal septum is called the columella or columella nasi, and is made up of cartilage and soft tissue. [2] 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
The sphenoid sinus is a paired paranasal sinus in the body of the sphenoid bone. It is one pair of the four paired paranasal sinuses. [1] The two sphenoid sinuses are separated from each other by a septum. Each sphenoid sinus communicates with the nasal cavity via the opening of sphenoidal sinus.
The inferior nasal concha (inferior turbinated bone or inferior turbinal/turbinate) is one of the three paired nasal conchae in the nose. It extends horizontally along the lateral wall of the nasal cavity and consists of a lamina of spongy bone , curled upon itself like a scroll, ( turbinate meaning inverted cone). [ 1 ]
In mammalian anatomy, the cribriform plate (Latin for lit. sieve-shaped), horizontal lamina or lamina cribrosa is part of the ethmoid bone.It is received into the ethmoidal notch of the frontal bone and roofs in the nasal cavities.
