Posterior Rhinoscopy Mirror

This instrument is the St. Clair Thompson post-nasal or posterior rhinoscopy mirror.

Uses:

Examination of the post nasal space by a procedure called posterior rhinoscopy, an out-patient procedure.
The mirror is warmed and introduced into the oral cavity while the tongue is depressed with a tongue depressor. The mirror is turned upwards in order to examine the post nasal space.

The shaft of the instrument is bent to achieve a bayonet shape, a feature that helps differentiate it from the indirect laryngoscopy mirror. The mirror is available in 5 sizes.

More Information:

• Posterior rhinoscopy is done to look for lesions in the post nasal space - for example, adenoids, tumours of the nasopharynx, etc.
• Diagnostic nasal endoscopy is the best method to examine this region.
• In small children who may be uncooperative for posterior rhinoscopy or nasal endoscopy, X-ray of the skull, lateral view, may be used to rule out adenoids.
