Olfactory Cleft Stenosis and Obstruction on Paranasal Sinus CT Scan in Pre Septo Rhinoplasty Patients Without Respiratory Mucosa Pathology : Normal Variants or Pathologic Findings ?

France75 participantsStarted 2023-08-01

Plain-language 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).

Inclusion Criteria: * Patients over 18 years old who underwent paranasal sinus CT and olfactory test before septoplasty or septorhinoplasty Exclusion Criteria: * 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)

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
