Chronic rhinosinusitis, an inflammation of the nose and sinuses, often causes smell loss. While treatments can temporarily improve olfactory function, the effects are typically incomplete and short-lived.

Area of Science:

  • Otolaryngology
  • Rhinology
  • Neuroscience

Background:

  • Chronic rhinosinusitis (CRS) is a persistent inflammatory condition affecting the nasal and sinus mucosa for over 12 weeks.
  • CRS frequently leads to olfactory dysfunction, commonly known as smell loss.
  • Smell loss significantly impacts quality of life, causing safety, hygiene, appetite, and emotional issues.

Purpose of the Study:

  • To review the relationship between chronic rhinosinusitis and olfactory dysfunction.
  • To assess the treatability and outcomes of smell loss associated with sinonasal disease.

Main Methods:

  • Literature review of studies investigating chronic rhinosinusitis and smell loss.
  • Analysis of treatment efficacy for olfactory dysfunction in CRS patients.

Main Results:

  • Chronic rhinosinusitis is a primary cause of treatable olfactory dysfunction.
  • Treatment for CRS can lead to improvements in olfactory sensation.
  • Observed improvements in smell are often transient and incomplete.

Conclusions:

  • Olfactory dysfunction is a significant consequence of chronic rhinosinusitis.
  • Current treatments offer limited long-term restoration of smell in CRS patients.
  • Further research is needed for more effective olfactory dysfunction management in CRS.
