Background Methods Results Conclusion The inability of topical medications to reach sinus cavities is a potential reason for lack of efficacy in chronic rhinosinusitis (CRS). One purpose of endoscopic sinus surgery (ESS) is to enable delivery of medications into the sinus cavities. The exhalation delivery system with fluticasone (EDS‐FLU; XHANCE) creates unique biomechanics that enable deposition of intranasal corticosteroid into sinuses and sinus drainage pathways but may have differing efficacy in operated versus unoperated sinuses. Two 24‐week randomized trials (ReOpen1/2) evaluated EDS‐FLU versus EDS‐placebo in patients with CRS, stratified by surgical status.Surgery‐naive (n = 332) and prior‐surgery (n = 215) patient groups were analyzed as pooled data from ReOpen1/2. Outcome measures (least‐squares mean change from baseline) included combined symptom score (CSS) and congestion score at weeks 4, 8, and 12 and average of percentages of opacified volume (APOV) of ethmoid/maxillary sinuses on CT and Sinonasal Outcome Test 22 (SNOT‐22) total score at week 24.Baseline scores suggested moderate–severe disease: mean CSS = 5.8; APOV = 67.2%. EDS‐FLU produced significant improvement versus placebo (p < 0.05): CSS (surgery‐naive, −0.68 vs. −1.42; prior ESS, −0.70 vs. −1.87); congestion (surgery‐naive, −0.24 vs. −0.59; prior ESS, −0.24 vs. −0.69); and SNOT‐22 (surgery‐naive, −7.56 vs. −18.30; prior ESS, −10.72 vs. −18.74). Similar results were observed for APOV (p < 0.05). No statistically significant difference was observed between surgery subgroups with either EDS‐FLU dose.EDS‐FLU improved symptoms, sinus opacification, and quality of life in patients with CRS with or without prior ESS, suggesting a role for EDS‐FLU in both populations.

Background Methods Results Conclusions Sinonasal malignancy surveillance paradigms are often based on Head and Neck National Comprehensive Cancer Network guidelines, which do not recommend standard surveillance imaging beyond 6 months without concerning symptomatology or physical examination findings.This was a retrospective analysis of all patients who underwent resection of sinonasal malignancy at a tertiary care center over a 20‐year period from 2000 to 2020, with an ensuing surveillance period demonstrating recurrence.Fifty‐two patients with sinonasal malignancy recurrence were included, with an average time to recurrence of 30.9 months and a follow‐up period of over 60 months. Recurrence was diagnosed by routine imaging or endoscopy in asymptomatic patients in a majority (60%) of cases, while the remaining minority of diagnoses followed new symptomatology. Asymptomatic recurrence was associated with perineural spread of tumor at initial resection (p = 0.025), but not with age (p = 0.85) or stage at diagnosis (p = 0.68). Expectedly, positron emission tomography/computed tomography (CT) more often detected regional or distant recurrence, while structural imaging (CT/magnetic resonance imaging) demonstrated more frequent detection of recurrence in those with perineural spread of tumor (p = 0.01).Our findings support high rates of asymptomatic recurrence in sinonasal malignancy, with the majority of recurrences diagnosed by routine endoscopy or imaging. Tailored and extended surveillance guidelines are necessary relative to those utilized for other head and neck mucosal cancers, and are especially appropriate when features such as perineural spread are present.
