There is a paucity of data on dacryocystorhinostomy (DCR) techniques and outcomes for NLDO secondary to known sinonasal pathologies.ObjectiveTo describe case characteristics, management, and surgical outcomes of sNLDO at a tertiary academic center.MethodsCharts of DCR cases with at least 3 months follow-up done at a single institution over a 5-year period (2018-2022) were reviewed. Patient and surgical characteristics were recorded and compared between secondary and primary NLDO groups. The primary outcome was early functional success of DCR, assessed by improvement or resolution of epiphora at 3 months.ResultsA total of 236 cases were included. Of those, 79 (33.5%) were classified as secondary NLDO associated with sinonasal pathology. Reasons for sNLDO were sinonasal cancer (46.8%), chronic inflammatory disease (24.1%), trauma (16.5%), or prior head and neck radiation (31.6%). When comparing primary acquired NLDO to sNLDO cases, DCR for sNLDO was more likely to be performed endoscopically (68.4% vs 31.8%, <i>P</i> < .01), by a multidisciplinary team of rhinologist and oculoplastic surgeon (70.9% vs 8.3%, <i>P</i> < .01), and required bilateral surgery (36.7% vs 5.7%, <i>P</i> < .01). The overall functional success rate was 79.7% for sNLDO compared to 87.9% for primary acquired NLDO (<i>P</i> < .01). Revision surgery for sNLDO, history of sinonasal malignancy, and radiation were associated with lower functional success rates (66.7%, 70.3%, and 68.0%, respectively). Canalicular pathology was more common in sNLDO cases (29.0% vs 8.3%, <i>P</i> < .01).ConclusionsSecondary NLDO was more commonly managed with an endoscopic approach by a multidisciplinary team. Revisions for sNLDO, as well as cases with a history of sinonasal malignancy and radiation, had a markedly lower success rate, and sNLDO was frequently associated with canalicular obstruction.

This study aimed to investigate the role of peroxiredoxin 2 (PRDX2) in CRSwNP and its potential mechanisms.MethodsProteomics analysis was conducted on nasal tissues from CRSwNP patients and healthy controls. Top-rank differentially expressed proteins were validated by immunofluorescence (IF) staining and reverse transcription quantitative-polymerase chain reaction (RT-PCR). In vitro experiments validated the effects and regulatory mechanisms of PRDX2 on nasal epithelial remodeling.ResultsProteomics results revealed a disease-specific protein expression profile in CRSwNP polyp tissues, with DEGs primarily associated with oxidative stress. Our validation results demonstrated elevated reactive oxygen species (ROS) levels in CRSwNP with predominant accumulation in the nasal epithelium. Among these DEGs, PRDX2 was the most significantly downregulated, which was further confirmed by RT-PCR and IF. Moreover, PRDX2 was primarily expressed in nasal epithelial cells (NECs). RT-PCR results indicated that tissue PRDX2 expression was positively correlated with E-cadherin and negatively correlated with TGF-β1 and Vimentin expression in CRSwNP. In vitro experiments demonstrated that H₂O₂ stimulation promoted ROS and epithelial-mesenchymal transition (EMT) in NECs, while PRDX2 overexpression (OE) mitigated these effects. Furthermore, PRDX2 OE suppressed the H₂O₂-induced activation of the TGF-β1/SMAD signaling pathway, which plays a crucial role in regulating EMT in NECs.ConclusionOur findings suggest that the accumulation of ROS plays a critical role in the pathogenesis of CRSwNP.
