This is an outdated method of ear wax removal, this procedure has lost its popularity over the years in favour of ear irrigation. An old-fashioned metal syringe is used to pump water into the ear canal in an attempt to dislodge and flush out ear wax.
These are rarely used today and substitured by lower pressued plastic syringes. This method is no longer used by NHS nurses or GP's. This method is now self administered by people using ear syringing kits bought online or over the counter. They typically contain a bulb or flared type plastic syringe and is designed to squirt streams of water at different angles against the ear canal wall.
The idea behind syringing is for water to get pumped "in behind" the wax to try and flush it out of the ear. Standard procedure time can take from 15-30 minutes, but this can vary depending on depth of wax in the canal, shape of canal, type and amount of wax and whether you are having one or both ears cleared. This is usually performed with the person sat still, with their head slightly tilted, so the ear being treated is facing upwards. As the water runs back out, a cup-shaped basin is placed beneath the ear to collect the water and any wax that may have been flushed out. .
Syringing can be effective at removing wax if performed correctly and safely.
