简要总结
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).
详细描述
In this retrospective study, We will include every patients over 18 years old who had a septoplasty or septorhinoplasty between December 2013 and December 2021 and who underwent paranasal CT scan and olfactory test (sniffin stick test).
The patients will be find thanks to social security code GAMA007 for septoplastie, GAMA 004, 010 for septorhinoplasty and olfactometry GJQP001.
The patients with mucosa pathology on CT scan or with record of chronic respiratory rhinitis, septum perforation or a pathology that can alter the olfaction on the consultation report will be excluded.
Olfactory measurements were performed before surgery using the threshold and identification subtests of Sniffin Stick Test. Olfactory status will be classified by taking into account the normative data provided by Hummel et al and the real identification score. The patients will be classified as normosmic if the threshold and the identification score is superior the tenth percentile. If not, they will be classified as anosmic if both score are 0 and hyposmic otherwise.
2 experienced radiologists will perform the measures on paranasal sinus CT. They will be blinded to olfactory results.
