What assessment method is used to gauge the movement of the tympanic membrane?

The assessment method used to gauge the movement of the tympanic membrane is pneumatic otoscopy. This technique involves the use of a specialized otoscope equipped with a bulb that can create positive and negative pressure in the ear canal. When this pressure change occurs, it causes the tympanic membrane to move. By observing these movements, healthcare providers can assess the flexibility and responsiveness of the tympanic membrane, which is vital for diagnosing conditions such as middle ear effusion or otitis media.

In contrast, otoscopy is primarily used to visualize the ear canal and tympanic membrane, helping in identifying physical obstructions or abnormalities but does not measure movement. Audiometry focuses on testing hearing acuity rather than tympanic membrane movement. Rhinoscopy pertains to the examination of the nasal passages and is unrelated to the assessment of the tympanic membrane. Therefore, pneumatic otoscopy is the most appropriate method for evaluating tympanic membrane movement.
