Amaç: Çalışmamızın amacı koku maruziyet süresinin koku eşiği, koku alma ve ayırt etme üzerine etkisinin değerlendirilmesi idi.

Yöntem: Doksan sağlıklı erişkin randomize olarak 3 gruba ayrıldı. Grup 1’e standart koku maruziyet süresi (3–4 sn), Grup 2’ye 8–10 saniye ve Grup 3’e ise 30 saniye koku maruziyet süresi koku testi uygulandı. Her üç gruba ait koku parametreleri karşılaştırıldı.

Bulgular: Grup 2 ve 3, Grup 1’e göre anlamlı oranda daha iyi koku tanıma skorlarına sahipti. Üç grup arasında koku eşiği ve koku ayırt etme skorları açısından anlamlı fark yoktu. Grup 3’teki erkekler Grup 1 ve 2’dekilere göre, Grup 2 ve 3’teki kadınlar ise Grup 1’dekilere göre anlamlı oranda daha iyi koku tanıma skorlarına sahip idi.

Sonuç: Mevcut çalışmanın sonuçları uzun koku uyarısının yüksek koku tanıma skorlarına yol açtığını gösterdi. Bununla birlikte, koku eşiği ve koku ayırt etme koku maruziyet süresinden bağımsız idi. Koku tarama testlerindeki koku maruziyet süreleri bizim bulgularımızla uyumlu olarak cinsiyete göre revize edilebilir.

Anahtar sözcükler: Koku maruziyet süresi, koku tanıma, koku eşiği, koku ayırt etme, Sniffin’ sticks.

Impact of odor exposure time on olfactory parameters

Öz

Objective: The aim of this study was to assess the impact of odor exposure time on odor threshold, odor identification and discrimination.
Methods: Ninety healthy volunteers were randomly divided into three
groups: Group 1 underwent an olfactory test with the standard odor
exposure time (3–4 sec), Group 2 had an odor exposure time of 8–10
seconds, and Group 3 had 30 seconds. Odor parameters of three groups
were compared.

Results: Groups 2 and 3 had significantly better odor identification scores
than Group 1. There were no statistically significant differences between
the three groups in terms of mean odor threshold and discrimination
scores. Males of Group 3 had significantly better odor identification
scores than males of Groups 1 and 2 and females of Groups 2 and 3 had
significantly better odor identification scores than females of Group 1.
Conclusion: The results of the present study showed that longer odor
stimulation led to higher odor identification scores. However, odor
threshold and odor discrimination were independent from the odor
exposure time. The odor exposure time of olfactory screening tests may
be revised according to the gender in accordance with our findings
