Overview

The prevalence of adenoiditis is not completely known. In 2015, the prevalence and incidence of adenoiditis was estimated to be 12000 cases per 100,000 individuals worldwide.[1] The prevalence of adenoiditis decreases with age. Adenoid tissue go through atrophy process after 10 years of age so adeoiditis is rarely seen after 15 .[2]

Epidemiology and Demographics

Prevalence

  • The prevalence of adenoiditis is not completely known.
  • In 2015, the prevalence of adenoiditis was estimated to be 12000 cases per 100,000 individuals worldwide.[1]

Incidence

  • The prevalence of adenoiditis is not completely known.
  • In 2015, the incidence of adenoiditis was estimated to be 12000 cases per 100,000 individuals worldwide.

Case Fatality Rate

  • The case fatality rate of tonsillitis is unknown.

Age

  • Adenoiditis commonly affects children.
  • The prevalence of adenoiditis decreases with age.
  • Adenoid tissue undergo atrophy after 10 years of age so adenoiditis is rarely seen after 15.
  • Adenoiditis can be seen in adults too, although it is rare in this patient population. However due to improved diagnostic modalities, adenoiditis is usually treated or removed during childhood.

Gender

  • Adenoiditis does not show predilection for any gender.

Race
