for use in the ear canal; smaller than Tilly's and has a better "biting" action •Hunter Tod's forceps: for use in the ear canal •Fagge's aural forceps: for use in the ear canal •Waugh's long dissecting forceps: used for dissection like on the tonsils, also to catch bleeding points and putting in swabs •Wilson's tonsil artery forceps
This is the method used in the original discovery of X-ray diffraction. Laue scattering provides much structural information with only a short exposure to the X-ray beam, and is therefore used in structural studies of very rapid events (time resolved crystallography). However, it is not as well-suited as monochromatic scattering for determining ...
Excess tears flow through the nasolacrimal duct which drains into the inferior nasal meatus. This is the reason the nose starts to run when a person is crying or has watery eyes from an allergy, and why one can sometimes taste eye drops. This is for the same reason when applying some eye drops it is often advised to close the nasolacrimal duct ...
A detector is used to convert X-ray energy into voltage signals; this information is sent to a pulse processor, which measures the signals and passes them onto an analyzer for data display and analysis. [citation needed] The most common detector used to be a Si(Li) detector cooled to cryogenic temperatures with liquid nitrogen.
In medicine, a nasopharyngeal airway (NPA), nasal trumpet (because of its flared end), or nose hose, is a type of airway adjunct, a tube that is designed to be inserted through the nasal passage down into the posterior pharynx to secure an open airway. It was introduced by Hans Karl Wendl in 1958. [1]
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.

Involutional stenosis is probably the most common cause of nasolacrimal duct obstruction in older people. It affects women twice as frequently as men. Although the inciting event in this process is unknown, clinicopathologic study suggests that compression of the lumen of the nasolacrimal duct is caused by inflammatory infiltrates and edema.
