Abstract:
OBJECTIVE To analyze the value of modified sinus CT score in olfactory function evaluation before and after functional endoscopic sinus surgery in chronic rhinosinusitis with nasal polyps(CRSwNP). METHODS Fifty-four patients who underwent functional endoscopic sinus surgery for CRS with nasal polyps were enrolled in this prospective study by inclusion criteria and exclusion criteria. T&T methods and olfactory function VAS were used to analyze the subjective olfactory function and were performed preoperatively and at 6 months after surgery. In modified sinus CT score, middle turbinate and superior turbinate associated olfactory cleft areas were used to evaluate the anterior olfactory cleft score(AOCS) and posterior olfactory cleft score(POCS). Sinus CT scans Lund-Mackay scores were also collected before surgery. The correlation between the status of the olfactory cleft on CT, Lund-Mackay score and the preoperative and postoperative olfactory results were investigated.RESULTS Among 54 patients, there were 36 male and 18 female, with average age of 47.9 years old(from 24 to 67 years). There were 30 patients followed 6 months after surgery. The findings of olfactory cleft opacification and the CT Lund-Mackay scores had a positive correlation with preoperative olfactory results(P<0.001). The olfactory cleft opacification showed a stronger correlation with the preoperative olfactory results than the CT Lund-Mackay score. The AOCS was more significantly correlated with the postoperative olfactory results than the other parameters.CONCLUSION Preoperative CT findings, especially the anterior portion of the olfactory cleft had a statistically significant association with the postoperative olfactory results in patients with CRS with nasal polyps.
