Indeed, because balloon sinuplasty is a relatively atraumatic procedure, it is also a suitable treatment option for critically ill patients 12. Balloon sinuplasty improves quality of life and is safe and effective in adults as well as in children 5, 6, 7, 8, 9, 10, 11. Chronic rhinosinusitis is primarily treated clinically, although some patients still need an operation to ease the symptoms 1, 2.Įndoscopic sinus surgery (ESS) is a standard treatment alternative for chronic rhinosinusitis that is effective and improves the quality of life of patients, whereas balloon sinuplasty is a less invasive technique that does not remove any tissue, but instead remodels it 3, 4. Furthermore, it can develop into chronic rhinosinusitis which, in turn, can cause pathological changes to the mucosa of the nasal cavity. Rhinosinusitis is a common problem worldwide that can have a remarkable effect on quality of life. Balloon sinuplasty increased the size of the maxillary ostium and the result was maintained for 12 months after the operation.

Our conclusion is that the threedimensional measuring technique provides a reliable method to evaluate ostium dimensions. The association between SNOT-22 score and ostium patency were statistically significant before the operation. The number of patent ostia increased after the intervention. The changes were statistically significant ( p<0.05) in the axial diameter and the ostium area. We discovered that the balloon sinuplasty increased the size of the maxillary ostium in all dimensions. The association of changes in the SNOT-22 scores of the ostium was analysed. The size of the maxillary ostium was measured from the CBCT scans three-dimensionally. CBCT scans were taken and SNOT-22 Quality of Life questionnaire completed before and 12 months after the operation. This is a blinded retrospective trial in patients who had undergone balloon sinuplasty of the maxillary sinus. Our aim was to evaluate the effects of balloon sinuplasty on the size of the ostium in the maxillary sinuses in patients with chronic rhinosinusitis from cone beam computer tomography (CBCT) scans of the sinus.
