NCT06082193

Brief Summary

This retrospective studed included patients referred to our institution between December 2013 and december 2021 for septoplasty or septorhinoplasty. All patients underwent pre operatory paranasal sinus CT scan and olfactory test. Olfacory cleft stenosis will be quoted as none (less than 1/3 contact between nasal septum and ethmoïd turbinates), partial (1/3-2/3 contact between nasal septum and turbinates) or total (more than 2/3 contact between nasal septum and turbinates), as well as Olfactory Cleft obstruction as none (opacification less than 1/3 of olfactory cleft), partial (1/3-2/3 opacification) or complete (more than 2/3 opacification).

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

\- Patients over 18 years old who underwent paranasal sinus CT and olfactory test before septoplasty or septorhinoplasty without respiratory mucosa pathology Sex, mean age Olfactory test threshold and identification using sniffin stick test. Classification normosmic or hyposmic using Hummel table.

You may qualify if:

  • Patients over 18 years old who underwent paranasal sinus CT and olfactory test before septoplasty or septorhinoplasty

You may not qualify if:

  • Respiratory mucosa pathology on CT (polyposis, opacification of the maxillary sinuses, ethmoid cells, frontal sinus, sphenoidal sinus, sinonasal tumor)
  • septal perforation
  • chronic respiratory rhinitis (allergic, vasomotor, mucoviscidosis)
  • pathologie that can alter olfaction (multiple sclerosis, meningioma, post infection such as COVID)
