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?

  • The eardrum in OME will have a distinct bulge, indicating fluid buildup.
  • The eardrum in OME is often visibly red and inflamed.
  • The eardrum in OME is typically transparent and clear.
  • The eardrum in OME may appear thicker and less transparent, with a possible yellowish hue. (correct)

Why is it challenging to diagnose OME in children?

  • Children's eardrums are less susceptible to fluid buildup, making diagnosis difficult.
  • Children often have difficulty describing their hearing loss.
  • Children are often moving around, making it difficult to get a clear view of the eardrum. (correct)
  • Children's eardrums are smaller and more delicate, making examination difficult.

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.
