This study established normative olfactory function data for the Greek population using the "Sniffin' Sticks" test. Results show olfactory performance varies with age, sex, and nostril, with females and younger individuals performing better.

Area of Science:

  • Otolaryngology
  • Neuroscience
  • Psychophysics

Background:

  • Quantitative olfactory assessment is crucial for diagnosing olfactory loss, which can cause significant morbidity.
  • The
  • Sniffin' Sticks
  • is a validated tool for assessing nasal chemosensory performance, evaluating odor threshold, discrimination, and identification.

Purpose of the Study:

  • To establish normative olfactory function data for the Greek population using the
  • Sniffin' Sticks
  • test.
  • To investigate the influence of age, sex, and laterality on olfactory performance in Greeks.

Main Methods:

  • A prospective clinical trial involving 93 healthy Greek subjects (48 males, 45 females; age range 6-84 years).

  • Utilized the
  • Sniffin' Sticks
  • odor assessment battery (threshold, discrimination, identification).
  • Collected data on age, sex, and tested nostril (right, left, or bilateral).

    • Main Results:

    • Established a normative database for olfactory function in the Greek population.
    • Females demonstrated superior olfactory performance compared to males.
    • Older individuals exhibited reduced olfactory efficiency across all tested domains.
    • A significant advantage was observed for the right nostril over the left.
    • Bilateral presentation scores approximated those of the better-performing nostril.

    Conclusions:

    • The
    • Sniffin' Sticks
    • test is effective for evaluating olfactory performance in the Greek population.
    • Greek population's mean olfactory test values were higher than those reported from Central and Northern Europe.
