背景：已知反复短期暴露于气味中可改善获得性嗅觉功能障碍患者的嗅觉。目的是找出用于嗅觉训练的气味的分子量的差异是否影响嗅觉。我们假设一个更大的改善训练后，与轻分子（LWM）odors.Methods：一项前瞻性研究进行了创伤后（PTOL）和病毒后嗅觉丧失（PVOL）的患者。嗅觉训练进行了为期5个月。一组（n = 48）使用四种含有重分子（HWM; >150 g/mol）的气味，另一组（n = 48）使用含有LWM（
Background: Repeated short-term exposure to odors is known to improve olfaction in patients with acquired olfactory dysfunction. The aim was to find out whether differences in molecular weight of odors used for olfactory training influences olfaction. We hypothesized a greater improvement following training with light weight molecule (LWM) odors.Methods: A prospective study was performed in patients with posttraumatic (PTOL) and postviral olfactory loss (PVOL). Olfactory training was performed over a period of 5 months. One group (n = 48) used four odors containing heavy weight molecules (HWM; >150 g/mol) and another (n = 48) containing LWM (
