Abstract

Purpose: To correlate the pathologic features and heat shock protein 47 (HSP47) expression in the nasal mucosa and lacrimal sac with the surgical outcomes of endoscopic endonasal dacryocystorhinostomy (EDCR). Methods: Specimens of the nasal mucosa and lacrimal sac over the rhinostomy site were collected during the operation. Haematoxylin–eosin and immunohistochemical staining were performed to determine the pathologic features (inflammation, fibrosis, squamous metaplasia) and the expression of HSP47 in the epithelium and sub-epithelial glands of the nasal mucosa and lacrimal sac. The success or failure of EDCR was determined 6 months after surgery. Results: A total of 30 patients (30 eyes) were included in this study. Inflammation and squamous metaplasia of the nasal mucosa were not associated with the surgical outcome of EDCR (p = 0.485 and 0.069, respectively), but there was an association with fibrosis of the nasal mucosa (p = 0.003). In addition, HSP47 in the nasal mucosa was associated with the surgical outcomes (p = 0.005). Inflammation of the lacrimal sac was not associated with the surgical outcome of EDCR (p = 0.509), but fibrosis and squamous metaplasia of the lacrimal sac were (p = 0.005 and 0.008, respectively). Additionally, HSP47 in the lacrimal sac was associated with surgical outcomes (p < 0.001). Conclusion: Fibrosis and squamous metaplasia of the nasal mucosa and lacrimal sac lowered the success rate of EDCR. HSP47 also lowered the surgical success rate. Fibrosis was correlated with the expression of HSP47.
