Outcomes of endoscopic sinus surgery in patients with central compartment atopic disease

Central compartment atopic disease (CCAD) is a subtype of chronic rhinosinusitis (CRS). Research focusing on the endoscopic sinus surgery (ESS) outcomes of CCAD is limited. This study aimed to evaluate the outcomes of ESS in CCAD and compared to 2 following subtypes: chronic rhinosinusitis with nasal polyps (CRSwNP) and concomitant polypoid disease in the central compartment (CRSwNP/CC) and CRSwNP not otherwise specified (CRSwNP NOS).

This case-control study enrolled patients with bilateral CRSwNP who underwent ESS and had at least 1 year of follow-up. Patients were classified into CCAD, CRSwNP/CC, and CRSwNP NOS. The demographic data, preoperative disease severity, and surgery outcomes, including CRS control status, endoscopic score, and symptom scores at 1 year postoperatively, were collected. We defined well controlled and partly controlled as appropriate disease control.

This study screened 259 patients and enrolled 138 patients with complete medical records and 1-year follow-up (CCAD N = 51, CRSwNP/CC N = 55, CRSwNP NOS N = 32). Among them, appropriate disease control was achieved in 84.3% of patients (43/51) in the CCAD group, 69.1% (38/55) in the CRSwNP/CC group, and 93.7% (30/32) in the CRSwNP NOS group (P = 0.029). Then we performed post-hoc analysis using appropriate disease control and uncontrolled. There was a significant difference between CRSwNP/CC and CRSwNP NOS (P = 0.007), but no significant difference compared CCAD group to CRSwNP/CC group (P = 0.065) and CRSwNP NOS group (P = 0.199). There were significant differences in endoscopic E-score among groups (P < 0.001). In post-hoc analysis, we found that CRSwNP/CC (Median [IQR], 33.32 [42.14]) had a significantly worse E-score than CCAD (8.33 [16.67]) and CRSwNP NOS (4.17 [8.30]). Also, postoperative olfactory visual analog scale (VAS) scores significantly differed among groups (P = 0.043). However, post-hoc analysis showed no difference between any 2 groups. There were no differences in postoperative VAS scores of obstruction (P = 0.159), rhinorrhea (P = 0.398), and headache/facial pain (P = 0.092).

Most CCAD patients had good surgical outcomes 1 year after surgery. Meanwhile, the CRSwNP/CC group had the fewest patients under appropriate disease control.
