Face Weakness Facial Twitches
Pain in the face can arise from the sinuses, but other rare causes include migraine, neuralgia, jaw joint problems and other possibilities. An accurate description of the features of the pain often provides important clues.
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to study internal soft tissue structures in detail. It provides good contrast between the different types of tissue, which is a major advantage over CT. MRI does not use ionising radiation unlike CT or traditional X-rays. Instead it uses a powerful magnetic field to align tissue atoms, and then uses radiofrequency fields to change and record their alignment. This scanned information is then used to construct images of specific parts of the body. The commonest indication for an MRI scan is parotid or tongue tumours and sinus or skull base tumours.
The patient lies still on a couch with their head in a metal tube. Some patients find this enclosed experience unpleasant, which has resulted in the development of so-called “open scanners”.
Pure Tone Audiometry
This is a basic subjective hearing test to determine your ability to hear various sounds at different tone frequencies.
You will be required to sit in a soundproof booth with headphones and press a button every time you hear a bleep sound, even if it is very faint. You should ignore any rushing sounds used to mask the opposite ear and only react to the bleeps. This test may take up to 20 minutes depending on the results.
Why? This is an objective test of your middle ear function and is useful for determining whether: there is any fluid or congestion in your middle ear there is a perforation (hole) in your ear drum the ear drum is flaccid and weak there is loss of continuity of the ossicles (middle ear bones) by disease or trauma a grommet is blocked changing pressure in the ear canal causes dizziness indicating a fistula (defect) in the bone surrounding the labyrinth (balance organ) .
You are not required to do anything for this test other than sit very still. The audiologist will hold a soft rubber probe at the entrance of your ear canal and you may feel a slight change of pressure in your ear.
This objective test is to make sure that the stapedius muscle in your middle ear is functioning correctly and providing a protective mechanism by stablising the hearing bones of the middle ear by contracting to loud sounds.
You are not required to do anything for this test other than sit very still. The audiologist will hold a soft rubber probe at the entrance of your ear canal. You will hear a series of very loud bleeps but you are not required to respond to them.Book Appointment
