ObjectiveTo investigate the correlation between the preoperative CT LundMackay score and pre and/or postoperative visual analogue scale (VAS) of subjective symptom in chronic sinusitis patients with asthma.MethodsThe preoperative CT LundMackay scores and preand/or postoperative visual analogue scales (VAS) of subjective symptoms in 19 chronic sinusitis patients with asthma were analyzed retrospectively. Linear regression analysis and paired ttest were adopted to explore the results.ResultsThe preoperative CT LundMackay scores of ethmoidal sinus, ostiomeatal complex, frontal sinus were relatively high, and that of sphenoid sinus was the lowest. Before operation, the VAS of nasal obstruction and rhinorrhoea were relatively high and those of headache and dysosmia were relatively low. One year after operation, the scales changed greatly in nasal obstruction and rhinorrhea, and slightly in headache and dysosmia (all P<0.05). The preoperative CT LundMackay scores were positively correlated with VAS of the subjective symptoms both before and after operation (r=0.465,P=0.045; r=0.522,P=0.022 respectively).ConclusionNasal obstruction and rhinorrhoea are the primary nasal symptoms in chronic sinusitis with asthma. Surgical treatment can improve such symptoms as nasal obstruction, rhinorrhoea, headache and dysosmia, especially the former two. The preoperative CT LundMackay scores are well correlated with VAS of the subjective symptoms both before and after operation. It is important for chronic sinusitis patients with asthma to perform sinus CT scanning in evaluating the surgical outcomes.
