A beautiful video which demonstrates the insertion of grommet to treat a condition called glue ear ( otitis media with effusion ).
Otitis media with effusion (OME), also called serous or secretory otitis media (SOM), is simply a collection of fluid that occurs within the middle ear space as a result of the negative pressure produced by altered Eustachian tube function. This can occur purely from a viral URI, with no pain or bacterial infection, or it can precede and/or follow acute bacterial otitis media. Fluid in the middle ear sometimes causes conductive hearing impairment, but only when it interferes with the normal vibration of the eardrum by sound waves.
Over weeks and months, middle ear fluid can become very thick and glue-like (thus the name glue ear), which increases the likelihood of its causing conductive hearing impairment. Early-onset OME is associated with feeding while lying down and early entry into group child care, while parental smoking, too short a period of breastfeeding and greater amounts of time spent in group child care increased the duration of OME in the first two years of life.
This video explains the procedure of doing posterior rhinoscopy to visualise the turbinates and eustachian tube .
An important point to be noted here is that all the turbinates except the SUPERIOR TURBINATE can be visualised by posterior rhinoscopy .
