Background: The impact on quality of life (QoL) of bilateral inferior turbinate reduction (BITR) performed in the setting of endoscopic sinus surgery (ESS) for chronic rhinosinusitis (CRS) has been a point of controversy. The aim of this study was to determine whether addition of BITR to ESS is associated with improved QoL when compared with ESS alone., Methods: This study presented findings a multi-institutional, retrospective analysis of a prospective open cohort of patients electing ESS for failed medical management of CRS. QoL parameters were compared between patients who underwent ESS alone vs those who underwent ESS with BITR., Results: A total of 571 patients with CRS who elected to undergo ESS were identified. Sixty-one of these patients also underwent concurrent BITR, whereas 510 patients underwent ESS without BITR. Mean length of follow-up was 15.1 months. Comparison between baseline and last postoperative QoL, olfaction, and endoscopic scores revealed significant improvement in both groups. Overall, BITR surgery was not significantly associated with clinically significant incremental improvement in QoL in either the polyp or non-polyp group. Nevertheless, statistically significant improvement was noted for the nasal congestion/blockage symptom in polyp patients (p = 0.006) and in primary surgery patients (p = 0.027) who underwent BITR., Conclusion: BITR in the setting of ESS for CRS is not associated with significant incremental improvement in overall QoL vs ESS alone. However, BITR in polyp and primary surgery patients undergoing ESS appears to offer a significant incremental improvement in nasal congestion/blockage symptoms compared with ESS alone. Future studies are warranted to better corroborate these findings., (© 2019 ARS-AAOA, LLC.)

Background: Although the safety of topical nasal steroids is well established for nasal spray forms, data regarding the safety of steroid irrigations is limited. We studied the effect of long-term budesonide nasal irrigations (>6 months) on hypothalamic-pituitary-adrenal axis (HPAA) function and intraocular pressure (IOP) in patients post-endoscopic sinus surgery., Methods: This was retrospective case series. Adrenal function was assessed by using the high-dose cosyntropin stimulation test., Results: A total of 48 patients were assessed, with a mean duration of budesonide irrigations of 22 months. Stimulated cortisol levels were abnormally low in 11 patients (23%). None reported to have symptoms of adrenal suppression. Three of 4 patients who repeated the study being off budesonide for at least 1 month returned to near normal levels. Logistic regression analysis revealed that concomitant use of both nasal steroid sprays and pulmonary steroid inhalers was significantly associated with HPAA suppression (p = 0.024). Patients with low stimulated cortisol levels were able to continue budesonide irrigations under the supervision of an endocrinologist without frank clinical manifestations of adrenal insufficiency. IOP was within normal limits in all patients., Conclusion: Long-term use of budesonide nasal irrigations is generally safe, but asymptomatic HPAA suppression may occur in selected patients. Concomitant use of both nasal steroid sprays and pulmonary steroid inhalers while using daily budesonide nasal irrigations is associated with an increased risk. Rhinologists should be alerted to the potential risks of long-term use of budesonide nasal irrigations, and monitoring for HPAA suppression may be warranted in patients receiving long-term budesonide irrigation therapy., (© 2016 ARS-AAOA, LLC.)

Background: An increasing number of adult patients with cystic fibrosis (CF) are becoming candidates for elective endoscopic sinus surgery (ESS). We sought to identify perioperative factors in this patient population that were predictive of postoperative admission., Methods: Retrospective chart review of CF patients who underwent ESS during the years 2005 through 2012. Multiple preoperative, intraoperative, and immediate postoperative variables were analyzed., Results: Thirty-three patients who underwent 37 outpatient ESSs were identified. Successful same-day discharge was observed in 54%. In 46% of cases, postoperative admission was necessary, with a mean postoperative stay of 1.4 days. Pulmonary function, CF-related comorbidities, and history of lung transplant were not predictors of postoperative admission. Univariate analysis demonstrated that patients were more likely to be admitted if they had 1 of the following conditions: history of ≥4 prior ESS; procedure duration >2.5 hours; intraoperative blood loss greater than 150 mL; increased immediate postoperative pain scores; or larger narcotic requirements for pain control. On logistic regression analysis, a maximum pain score ≥ 7 out of 10 in the postanesthesia recovery unit was the only significant predisposing factor for postoperative admission., Conclusion: Although over 50% of adult CF patients can successfully undergo ESS on a same-day discharge basis, it is prudent to have contingent plans for potential inpatient observation postoperatively. Multivariate analysis suggests that preoperative demographics and pulmonary status cannot predict the need for postoperative admission, whereas higher pain scores in the postanesthesia care unit are predictive of the necessity for inpatient observation., (© 2014 ARS-AAOA, LLC.)

Background: New epithelial cells are generated through the proliferation and differentiation of resident progenitor cells in the nasal cavity. In several upper airway diseases, such as cystic fibrosis and chronic rhinosinusitis, self-renewing progenitor cells may be functionally defective, or compromised in their ability, to regenerate cells that maintain normal mucociliary clearance. Herein, we describe our early work to define and characterize a rare population of human nasal epithelial putative progenitors., Methods: Single-cell suspensions of human ethmoid sinus tissues were prepared following endoscopic sinus surgery. Cell surface antibodies were analyzed as candidate markers for detecting progenitor cells. A panel of antibodies, including epithelial cell adhesion molecule (EpCAM, epithelial cells), CD45 (hematopoietic cells), nerve growth factor receptor (NGFR/CD271), intercellular adhesion molecule-1 (ICAM1/CD54), and integrin-α6 (ITGA6/CD49f) were used to resolve epithelial progenitor candidates by high-dimensional flow cytometry and the gating technique of fluorescence minus one (FMO) controls., Results: A rare population of approximately 0.06% of total ethmoid cells was discriminated as EpCAM(-) CD45(-) NGFR(+) ICAM1(+) by surface markers. Use of ITGA6 was excluded based on FMO control analysis. This lineage-negative population was purified to 99% homogeneity by cell sorting and analyzed by immunofluorescence microscopy. Sorted cells were subsequently confirmed to uniformly express the transcription factor p63. Upon in vitro culture, lineage-negative clonal cells were confirmed to spontaneously differentiate into epithelial lineage-positive cells., Conclusion: Using the NGFR and ICAM1 cellular coordinates, we have identified a promising population of native human nasal epithelial progenitor cells that require more formal investigation for their role in upper airway regeneration., (© 2013 ARS-AAOA, LLC.)
