We would like to investigate our hypothesis of a higher prevalence of nasal fracture in the history of idiopathic rhinitis (IR) patients compared to healthy controls. Therefore a retrospective analysis of 310 patients with a nasal fracture in the past would be useful to investigate the incidence of IR in this cohort afterwards (5-10 y later).

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Comparison of the incidence of IR after nasal fracture in the patient population with the incidence of IR in the control group.
Timeframe: at least 1 year after surgery
