The septum generally stays in the midline until about the age of seven, at which point it will frequently deviate to the right. An operation to straighten the nasal septum is known as a septoplasty. A perforated nasal septum can be caused by an ulcer, trauma due to an inserted object, long-term exposure to welding fumes, [6] or cocaine use ...
Kiesselbach's plexus is an anastomotic arterial network (plexus) of four or five arteries in the nose supplying the nasal septum. It lies in the anterior inferior part of the septum known as Little's area, Kiesselbach's area, or Kiesselbach's triangle. It is a common site for anterior nosebleeds.
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] 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 cribriform plate forms the roof of the nasal cavity and also contributes to formation of the anterior cranial fossa, [4] the ethmoidal labyrinth consists of a large mass on either side of the perpendicular plate, and the perpendicular plate forms the superior two-thirds of the nasal septum. [3]
In this theory, mandibular condyle having cartilage at its end allows the downward and forward growth of the mandible. Maxilla, consisting of the nasal septum and nasomaxillary complex, which is made up of cartilage, moves forward and downward also by the forces from the nasal septum. Bones in both maxilla and mandible respond to their ...
Harvesting of nasal cartilage is minimally invasive, can be performed in an outpatient procedure under local anesthesia and is associated with minimal morbidity. [6] NC can be isolated from nasal septal cartilage biopsies by enzymatic digestion using collagenase type I, II or IV (at different combination and concentration – varying from 0.15% to 0.6% –) alone or after an initial short pre ...
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 ...
Decongestant nasal sprays containing oxymetazoline may provide relief, but these medications should not be used for more than the recommended period. Longer use may cause rebound sinusitis. [75] It is unclear if nasal irrigation, antihistamines, or decongestants work in children with acute sinusitis. [76]
