Glucocorticoid Receptor-β Overexpression According to Nasal Polyp Severity：Immunohistochemical Study

Background and Objectives：The aims of the study were to reintroduce a surgical technique for a “mini” Caldwell-Luc operation and to determine its efficacy. Materials and Methods：A prospective study was performed in 23 patients undergoing the “mini” Caldwell-Luc operation. Improvements in clinical symptoms and endoscopic and computed tomographic (CT) findings were evaluated postoperatively over a follow-up period ranging from 6 to 21 months. All patients were surveyed for nasal symptoms (nasal obstruction, rhinorrhea, posterior nasal drip, headache, and anosmia), complications (tooth or gum pain, numbness, persistent facial pain, and facial hypo-paresthesia), and recurrence. Preoperative nasal polyps were classified by the Gaskins method, and preoperative paranasal sinusitis was graded according to the Kennedy CT staging system. Results：Symptom scores were all significantly reduced postoperatively (paired t-test, p
