Objectives/Hypothesis: To describe the diagnostic criteria and treatments of concha compression syndrome (CCS). Patients and methods: Patients who reported at least 3 times rhinosinusitis attacks per year were considered in this study. All patients met the diagnosis criteria of rhinosinusitis based on clinical history, showed a nasal septal spur compressing concha on their endoscopic examination and had no findings of rhinosinusitis on their paranasal sinus CT scans but showed concha ondularis. These patients were recognized as suffering from CCS and consequently were surgically treated. Results: 85 patients diagnosed with CCS were included in this study. 25 of the patients were classified as middle, 53 as inferior and 7 as both middle and inferior CCS. Septal spur removal was performed on 16 of the patients whereas the remaining 69 patients received spur removal with septoplasty. After surgery, most of patients' symptoms improved clinically. Conclusion: The importance and the necessity of further investigations into this newly-defined syndrome in the differential diagnosis of rhino-neurogenic symptoms is made clear by this study.
