A positive Fortin finger test indicates a potential problem with a patient's hearing. It is a simple test that helps assess the mobility of the eardrum, which is essential for normal hearing.
How the Test Works
The Fortin finger test involves gently pressing on the tragus, the small cartilage flap in front of the ear canal. If the eardrum is mobile, the examiner will hear a clicking sound as the eardrum moves.
What a Positive Result Means
A positive Fortin finger test means that the eardrum is not moving when pressure is applied. This could indicate a number of issues, including:
- Otitis media (middle ear infection): Fluid buildup in the middle ear can cause the eardrum to become stiff and immobile.
- Tympanosclerosis: This condition involves thickening and hardening of the eardrum, which can also reduce its mobility.
- Eardrum perforation: A hole in the eardrum can prevent it from moving properly.
- Glue ear (otitis media with effusion): This condition involves fluid buildup in the middle ear, similar to otitis media, but without infection.
Importance of the Test
The Fortin finger test is a quick and easy way to assess the mobility of the eardrum. If the test is positive, it usually indicates a problem that requires further evaluation by a doctor.
