In posterior rhinoscopy, the endoscope is advanced through the mouth to examine the back of the nasal cavity above the soft palate, and can be used to visualise the oropharynx below that. Structures seen in posterior rhinoscopy: posterior border of nasal septum, fossa of Roosenmuller, eustachian tube opening and upper surface of soft palate.
•Thudichum's nasal speculum-do-; short blades ( uses: anterior rhinoscopy - to see the Little's area, ant-inferior part of nasal septum, anterior part of inferior and middle turbinate and meatus, as well as any pathological lesion in the area; also used in certain nasal operations ) •St. Clair Thompson's long bladed nasal speculum
In speech pathology and medicine, nasoendoscopy is the endoscopic examination of the velopharynx, or the nose, often with a CCD camera or a fiber optic camera on a flexible tube passed through the nostril. It can provide information to evaluate speech and velopharyngeal function or dysfunction, as in diseases such as sinonasal carcinomas. [1] [2]
Some polyps may be seen with anterior rhinoscopy (looking in the nose with a nasal speculum and a light), but frequently, they are farther back in the nose and must be seen by nasal endoscopy. [12] Nasal endoscopy involves passing a small, rigid camera with a light source into the nose.
A nasopharyngoscopy is a surgical procedure performed to examine the nose and throat.It is performed using a fiberoptic [1] instrument called a flexible fiberoptic nasopharyngoscope, [2] that is inserted through the nose in order to examine both it, and the back of the throat. [3]
A European consortium of the SME is working on the DUET (disposable use of endoscopy tool) project to build a disposable endoscope. [26] Capsule endoscopy Capsule endoscopes are pill-sized imaging devices that are swallowed by a patient and then record images of the gastrointestinal tract as they pass through naturally. Images are typically ...
An endoscopy is a simple procedure that allows a doctor to look inside human bodies using an instrument called an endoscope. A cutting tool can be attached to the end of the endoscope, and the apparatus can then be used to perform minor procedures such as tissue biopsies, banding of oesophageal varices or removal of polyps.
Rhinomanometry can be used to test nasal patency in basal conditions in order to differentiate between anatomical and mucosal abnormalities by performing a test with a decongestant. It can also be used to check impact of other treatments, like nasal steroid sprays, on objective nasal blockage.
