Results. Of 593 patients, 23 (3.9%) had PCMT and 44 (7.4%) had PSP. The PSP group was predominantly male (75% vs 52%, P < .001) with an older mean age (53.4 vs 35.4 years, P < .0001). PCMT was more often associated with allergic rhinitis (83% vs 34%, P < .001), whereas PCMT was rarely associated with chronic rhinosinusitis (10% vs 100%, P < .0001). Mean eosinophil count (7.1 vs 3.1, P = .08) was not significantly different between groups, whereas mean Lund-Mackay score was higher in PSP (14.9 vs 2.4, P < .0008). Mean NOSE score was greater in PSP (65.3 vs 44.3, P = .008), whereas SNOT-22 score was comparable between groups (40.6 vs 32.6, P = .14).
A total of 593 patients were prospectively screened with nasal endoscopy during the study period (Table 1). Of these, 23 (3.9%) were identified with PCMT and 44 (7.4%) were identified with PSP. When comparing the demographics between both groups, PSP patients were predominantly male (75% vs 52%, P < .001) with an older mean age (53.4 vs 35.4 years, P < .0001). Inhalant allergy was confirmed by either cutaneous or serologic testing in 19 patients in the PCMT group and 15 patients in the PSP group. A greater association was noted between PCMT and AR (83% vs 34%, P < .001), whereas PCMT was rarely associated with CRS (9% vs 100%, P < .0001). Among all sensitized patients, the most common aeroallergens were dust mites (47.5%), grasses (45.0%), trees (27.5%), and weeds (25.0%). No difference in the incidence of asthma was noted between study groups (34% vs 22%, P = .21). AERD was present in 14% of PSP patients but was not seen in the PCMT group (P = .024). No significant difference was found in the incidence of smoking between groups (9% vs 9%, P = .64).
Data on patient-reported QOL, imaging, and laboratory values are shown in Table 2. The mean NOSE score was greater in PSP (65.3 vs 44.3, P = .008), signifying a higher degree of nasal obstruction. SNOT-22 score was comparable between groups (40.6 vs 32.6, P = .14), with mean scores exceeding the minimum that would predict improvement from surgical management.11 The Lund-Mackay score was significantly higher in the PSP group compared with the PCMT group (14.9 vs 2.4, P < .0008), although CT was infrequently indicated and therefore not often performed in the PCMT group. The mean percentage of eosinophils in peripheral blood was not significantly different between groups (PSP 7.1 vs PCMT 3.1, P = .08). No difference was observed in mean total serum IgE, although because this information was obtained for only 21 of the 67 patients, that result may be difficult to interpret.
