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.
After removal of nasal packing following epistaxis, routine nasoendoscopy is not necessarily indicated. [3] However, widely accepted indications for nasoendoscopy include: [ 4 ] abnormal speech characteristics: hypernasal resonance, excessive nasal airflow including nasal air escape and nasal turbulence (also called nasal rustle), and absence ...
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.
However, such measurements allow only to detect in which side of the nose there is obstruction, not the location within the nasal cavity, which can be detected by acoustic rhinometry or endoscopy. Anterior rhinomanometry is more commonly used and it is often recommended for its easy technique.
Nasal endoscopy and clinical symptoms are also used to make a positive diagnosis. [28] A tissue sample for histology and cultures can also be collected and tested. [68] Nasal endoscopy involves inserting a flexible fiber-optic tube with a light and camera at its tip into the nose to examine the nasal passages and sinuses.
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.
The nasal cavities become roomy and are filled with foul smelling crusts which are black or dark green and dry, making expiration painful and difficult. Microorganisms are known to multiply and produce a foul smell from the nose, though the patients may not be aware of this, because the nerve endings (responsible for the perception of smell ...
Nasal surgery is a specialty including the removal of nasal obstruction that cannot be achieved by medication and nasal reconstruction. Currently, it comprises four approaches, namely rhinoplasty, septoplasty, sinus surgery, and turbinoplasty, targeted at different sections of the nasal cavity in the order of their external to internal positions.
