A nasopharyngeal airway inserted in the right nostril of a patient. The correct size airway is chosen by measuring the device on the patient: the device should reach from the patient's nostril to the earlobe or the angle of the jaw. [10] The outside of the tube is lubricated with a water-based lubricant so that it enters the nose more easily. [5]
The nasal cannula (NC) is a device used to deliver supplemental oxygen or increased airflow to a patient or person in need of respiratory help. This device consists of a lightweight tube which on one end splits into two prongs which are placed in the nostrils curving toward the sinuses behind the nose, and from which a mixture of air and oxygen flows.

An endotracheal tube is a specific type of tracheal tube that is nearly always inserted through the mouth (orotracheal) or nose (nasotracheal). It is a breathing conduit designed to be placed into the airway of critically injured, ill or anesthetized patients in order to perform mechanical positive pressure ventilation of the lungs and to ...
The canal containing the duct is called the nasolacrimal canal.It is formed by indentations in the inferior nasal conchae, maxilla and lacrimal bone.The canal drains into the nasal cavity through the anterior portion of the inferior meatus, which is between the inferior concha and the floor of the nasal cavity.
Rhinomanometry is a form of manometry used in evaluation of the nasal cavity. Rhinomanometry is a standard diagnostic tool aiming to objectively evaluate the respiratory function of the nose. It measures pressure and flow during normal inspiration and expiration through the nose.
Incisive bone is a term used for mammals, and it has been generally thought to be homologous to premaxilla in non-mammalian animals. However, there are counterarguments. According to them, the incisive bone is a novel character first acquired in therian mammals as a composition of premaxilla derived from medial nasal prominence and septomaxilla derived from maxillary promine
The pyramid-shaped maxillary sinus (or antrum of Highmore) is the largest of the paranasal sinuses, located in the maxilla. It drains into the middle meatus of the nose [1] [2] through the semilunar hiatus. It is located to the side of the nasal cavity, and below the orbit. [2]
It is situated superoposteriorly upon the lateral nasal wall, opening into the nasal cavity at the posterior portion of the ethmoidal infundibulum. [1] Its opening in the maxillary sinus is present upon the superior part of the medial wall of the sinus [ 2 ] [ 3 ] near the roof of the sinus ; [ 4 ] because of the position, gravity cannot drain ...
