Abstract
Background: Functional endoscopic sinus surgery (FESS) was historically predicated on targeted widening of narrow anatomic structures that caused postobstructive persistent sinus inflammation. It is now clear that chronic rhinosinusitis (CRS) is a multifactorial disease with subsets of patients which may require a more extensive surgical approach. This study compares quality‐of‐life (QOL) and disease severity outcomes after FESS based on the extent of surgical intervention.Methods: Participants with CRS were prospectively enrolled into an ongoing, multi‐institutional, observational, cohort study. Surgical extent was determined by physician discretion. Participants undergoing bilateral frontal sinusotomy, ethmoidectomy, maxillary antrostomy, and sphenoidotomy were considered to have undergone “complete” surgery, whereas all other participants were categorized as receiving “targeted” surgery. Improvement was evaluated between surgical subgroups with at least 6‐month follow‐up using the 22‐item Sino‐Nasal Outcome Test (SNOT‐22) and the Brief Smell Inventory Test (B‐SIT).Results: A total of 311 participants met inclusion criteria with 147 subjects undergoing complete surgery and 164 targeted surgery. A higher prevalence of asthma, acetylsalicylic acid (ASA) sensitivity, nasal polyposis, and a history of prior sinus surgery (p ≤ 0.002) was present in participants undergoing complete surgery. Mean improvement in SNOT‐22 (28.1 ± 21.9 vs 21.9 ± 20.6; p = 0.011) and B‐SIT (0.8 ± 3.1 vs 0.2 ± 2.4; p = 0.005) was greater in subjects undergoing complete surgery. Regression models demonstrated a 5.9 ± 2.5 greater relative mean improvement on SNOT‐22 total scores with complete surgery over targeted approaches (p = 0.016).Conclusion: Complete surgery was an independent predictor of greater postoperative SNOT‐22 score improvement, yet did not achieve clinical significance. Further study is needed to determine the optimal surgical extent.
