The nasal septum is the bone and cartilage in the nose that separates the nasal cavity into the two nostrils.The cartilage is called the quadrangular cartilage and the bones comprising the septum include the maxillary crest, vomer, and the perpendicular plate of the ethmoid.
Rhinomanometry may be used to measure only one nostril at a time (anterior rhinomanometry) or both nostrils simultaneously (posterior rhinomanometry). In anterior rhinomanometry, the patient is asked to blow his nose, sit in an upright position, and the pressure sensing tube is placed in one nostril, while the contralateral nostril is left opened.
Many problems can affect the nose, including: Deviated septum - a shifting of the wall that divides the nasal cavity into halves; Nasal polyps - soft growths that develop on the lining of the nose or sinuses; Nosebleeds; Rhinitis - inflammation of the nose and sinuses sometimes caused by allergies. The main symptom is a runny nose.
Vomer bone; The lowest part of the septum is a narrow strip of bone that projects from the maxilla and the palatine bones, and is the length of the septum. This strip of bone is called the maxillary crest; it articulates in front with the septal nasal cartilage, and at the back with the vomer. [5]
The two incisive canals usually (in 60% of individuals) have a characteristic Y-shaped or V-shaped morphology: above, each incisive canal opens into the nasal cavity on either side of the nasal septum as the nasal foramina; below, the two incisive canals converge medially to open into the oral cavity at midline at the incisive fossa [1] as several incisive foramina.
The human nose is the first organ of the respiratory system.It is also the principal organ in the olfactory system.The shape of the nose is determined by the nasal bones and the nasal cartilages, including the nasal septum, which separates the nostrils and divides the nasal cavity into two.
Purvi Parikh, M.D., an allergist with Allergy & Asthma Network, recommends blowing one nostril at a time by putting a finger or pressure on one side of your nose, closing that nostril, and blowing ...
With age, the enlarging maxillary sinus may even begin to surround the roots of the maxillary posterior teeth and extend its margins into the body of the zygomatic bone. If the maxillary posterior teeth are lost, the maxillary sinus may expand even more, thinning the bony floor of the alveolar process so that only a thin shell of bone is ...
