Questions and Answers

What is the primary reason why the eardrum can appear opaque in middle ear effusion (OME)?

The eardrum is thickened due to a build-up of earwax.

The presence of a thick mucoid fluid in the middle ear. (correct)

The presence of air bubbles in the middle ear.

The eardrum is inflamed and red.

How does the appearance of the eardrum in a patient with OME differ from a normal eardrum?

Study Notes

Understanding Otitis Media and Ear Disorders

Otitis media is inflammation or infection of the middle ear.
Hiss is someone's name who discovered how ears are formed during embryogenesis.
Primordial embryological tissue forms the pina (auricle).
Cauliflower ear is a cosmetic issue.
Keloids are hypertrophic or excessive scarring.
Keloids are more common in African Canadian and African American populations.
Keloids tend to form following superficial trauma.
Otitis media is common and frequently causes visits to healthcare providers.

Otitis Media Subtypes

Acute Otitis Media (AOM): An actual acute infectious disease. This presents with signs and symptoms of acute inflammation, such as fever and pain.
Chronic Supportive Otitis Media (COME): A different entity. There is middle ear effusion (fluid) but without signs/symptoms of acute inflammation.
Subacute Otitis Media: A state between acute and chronic otitis media.
Otitis Media with Effusion (OME): Middle ear effusion without signs or symptoms of acute inflammation. This is often asymptomatic.

Pathophysiology of Otitis Media

The eustachian tube connects the middle ear to the nasopharynx.
The eustachian tube is important for equalizing air pressure between the middle ear and the atmosphere to prevent discomfort.
Obstruction or dysfunction of the Eustachian tube can lead to pressure imbalance, resulting in fluid buildup in the middle ear.
Upper respiratory infections are common causes of OME, as nasal congestion and inflammation can interfere with eustachian tube function.
Allergies and other conditions that cause inflammation can contribute to eustachian tube dysfunction.

Diagnosis and Treatment of Otitis Media

Otitis media can be diagnosed by observing signs and symptoms and examining the eardrum.
The presence of fluid or pus behind the eardrum can be a significant indicator.
Treatments for AOM may include antibiotics to address bacterial infection.
For OME, observation and management to allow inflammation to clear is often the best approach.
Ear tubes (tympanostomy tubes) can be used in cases of repeated AOM or persistent OME.
