A randomized controlled trial on triamcinolone versus saline impregnated merocel post endoscopic sinus surgery: Our experience in a tertiary care centre. World J Otorhinolaryngol Head Neck Surg 2024; 10:193-199. [PMID: 39233860 PMCID: PMC11369795 DOI: 10.1002/wjo2.108] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Revised: 02/20/2023] [Accepted: 03/05/2023] [Indexed: 09/06/2024] Open
Abstract
Purpose To assess the potential benefit of impregnating Merocel (a non-absorbable nasal dressing) with a topical steroid solution, for use as a direct and slow local delivery system of steroids after sinus surgery to improve postoperative wound healing. Methods In this randomized controlled trial, 40 patients with bilateral chronic rhinosinusitis with nasal polyposis were subjected to functional endoscopic sinus surgery. Following the completion of the surgery, Merocel packs were inserted in the bilateral nasal cavities and infiltrated with 4 mL triamcinolone (40 mg/mL) in one nasal cavity (treatment group) and 4 mL normal saline in the other (control group). Nasal packs were removed on the third postoperative day and postoperative healing assessment was done on postoperative Weeks 1, 2, 4, and 12. The findings were noted as per Lund Kennedy (LKES) and perioperative sinus endoscopy (POSE) scores and compared on both sides. Results Significant (P < 0.05) improvement was noted in Lund Kennedy score for crusting and polyp at Week 12, for edema at Week 1, and nasal discharge at Weeks 1 and 12, but there was no significant improvement in scarring at any week. Overall, the difference between the treatment and control arms was statistically significant at all postoperative visits except at Week 4. Also, there was a significant improvement in POSE scores at Weeks 1, 2, and 12 but not at Week 4. Conclusion This study positively concludes that the nasal cavity packed with drug-soaked packs had less scarring and edema in the postoperative period and the overall wound healing was much better as compared to saline-soaked packs.

Abstract
PURPOSE Endoscopic sinus surgery (ESS) is the standard treatment strategy for chronic rhinosinusitis (CRS) resistant to medical treatment, and it is known to have postoperative complications and recurrences, which in turn result in suboptimal outcomes. Several methods are used to prevent postoperative scarring, adhesions, oedema, infection or recurrences in cavities. The role of steroids in improving postoperative outcomes is well established. They can be administered systemically or locally to enhance drug delivery into paranasal sinuses. In this study, we used triamcinolone irrigation immediately following surgery on one side of the nose, in patients with bilateral disease. The objective of this study was to evaluate the effect of intra-operative triamcinolone irrigation on postoperative outcomes, in patients with bilateral pansinusitis. METHODS It was an interventional randomized controlled study, conducted at a tertiary care centre in North India. The analysis of 58 patients with bilateral pansinusitis was done from September 2020 to August 2021. At the conclusion of ESS, each patient was randomized to receive triamcinolone irrigation (4 ml of 40mg/ml solution) once and followed by merocel (polyvinyl acetal) packing on one side, while the contralateral side was packed with merocel soaked with saline. Nasal cavities were evaluated using a Hopkins rod endoscope in the postoperative 1st, 3rd, 8th and 12th weeks to look for the presence of postoperative crusting, oedema, polypoidal changes, and discharge. Perioperative sinus endoscopic scores (POSE) were used for endoscopic staging. RESULTS The most commonly affected age group was 31-45 years accounting for 39.7%. Males were affected more (63.7%) than the female population (36.3%). There was a reduction in the average POSE scores at the treatment site at all follow-up stages with a significant reduction in crusting, oedema, and scarring in the treatment site (P-value <0.001). CONCLUSION Triamcinolone irrigation effectively improves postoperative outcomes and reduces early postoperative complications in CRS patients.

Abstract
Pediatric upper airway disorders are frequently life-threatening and require precise assessment and intervention. Targeting these pathologies remains a challenge for clinicians due to the high complexity of pediatric upper airway anatomy and numerous potential etiologies; the most common treatments include systemic delivery of high dose steroids and antibiotics or complex and invasive surgeries. Furthermore, the majority of innovative airway management technologies are only designed and tested for adults, limiting their widespread implementation in the pediatric population. Here, we provide a comprehensive review of the most recent challenges of managing common pediatric upper airway disorders, describe the limitations of current clinical treatments, and elaborate on how to circumvent those limitations via local controlled drug delivery. Furthermore, we propose future advancements in the field of drug-eluting technologies to improve pediatric upper airway management outcomes.

Abstract
BACKGROUND Chronic rhinosinusitis affects approximately 5%-2% of the general population worldwide. Steroid implants after endoscopic sinus surgery (ESS) have drawn considerable interest for their cost savings, but relevant guidelines indicate that evidence on this topic is of low quality with high heterogeneity. The purpose of this study was to examine the efficacy of steroid implants after ESS by synthesizing relevant randomized controlled trials (RCTs). METHODS Two authors independently assessed the eligibility of potential references from five biomedical databases. They further extracted relevant data from the included studies, including (a) mean, standard deviation, or standard error for Lund-Kennedy endoscopic (LKE) score and Perioperative Sinus Endoscopy (POSE) score and (b) events and sample sizes of each group for further intervention. Data were pooled in a random-effects model, and results were presented as the weighted mean difference (WMD) or risk ratio (RR) with 95% confidence interval (CI) and I2 . RESULTS Eleven RCTs (n = 853) were included and showed that the steroid implant group had lower LKE scores (WMD, -1.19; 95% CI, -1.75 to -0.62; I2 = 0%) and POSE scores (WMD, -1.62; 95% CI, -2.47 to -0.76; I2 = 48%) than the placebo implant group at postoperative week 2. Moreover, the reoperation rate in the steroid implant group was also lower than in the placebo implant group (RR, 0.49; 95% CI, 0.30 to 0.80; I2 = 0%). However, no significant difference was observed in the postoperative oral steroid requirement between both groups. CONCLUSIONS Collectively, steroid implant decreases LKE and POSE among patients receiving ESS in the short term, but long-term effects remain unclear. Patient-based outcomes are worth further discussion in the future.

Abstract
Chronic rhinosinusitis is an upper respiratory disease during which topical drug treatment via the nasal cavity is the most actively utilized therapeutic strategy. In addition to steroids, antibiotics, and antifungal agents, which are widely used in clinical practice, research on novel topical agents to improve the bacterial biofilm or mucociliary clearance remains ongoing. Moreover, owing to the complex structure of the nasal cavity, the effects of nasal drug delivery vary depending on factors related to delivery fluid dynamics, including device, volume, and compounds. In this article, we review methods and compounds that have been applied to chronic rhinosinusitis management and introduce recent advances and future perspectives in nasal drug delivery for upper respiratory diseases.

Abstract
OBJECTIVE To evaluate the efficacy of absorbable steroid-impregnated nasal packing on postoperative outcomes following functional endoscopic sinus surgery (FESS) for chronic rhinosinusitis (CRS). METHODS A systematic review of the literature was conducted as per Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Twelve databases (including Journals@Ovid, Embase®, Medline®, EBM Reviews and Joanna Briggs Institute EBP Database) were searched using relevant keywords and expanded with corresponding MeSH/Emtree terms. Results were narrowed to English articles assessing the efficacy of absorbable packing impregnated with steroids post-production placed at time of surgery under general anesthetic, with hollow-lumen devices and devices inserted in-office excluded. RESULTS Eight studies met criteria and were included in this review. Five evaluated the efficacy of the intervention in only CRS with nasal polyposis (CRSwNP) patients, two included all subtypes of CRS, and one included only CRS without nasal polyposis (CRSsNP). Of the eight studies, four studied the efficacy of Nasopore®, three studied bioabsorbable gels, and one studied bioabsorbable calcium alginate. Four studies applied triamcinolone as the operative steroid, with the other studies utilizing betamethasone, budesonide, mometasone, and dexamethasone. Seven studies demonstrated statistically significant improvements in endoscopic outcomes using validated scoring scales, albeit at differing timepoints. The one study which included only CRSsNP patients failed to find a significant difference. CONCLUSION Steroid-impregnated nasal packing appears to have positive effects on postoperative endoscopic outcomes in CRSwNP patients undergoing FESS. Additional research is needed to evaluate the efficacy of these interventions in more recently defined subtypes of CRS, and whether these interventions differ in their efficacy in eosinophilic and non-eosinophilic CRS.

Abstract
OBJECTIVES To provide an overview of recent techniques and technologies for the application of topical corticosteroid therapy immediately following endoscopic sinus surgery (ESS) for chronic rhinosinusitis (CRS). METHODS A comprehensive search in the PubMed and Google Scholar databases was conducted to identify publications between January 2000 and December 2019 detailing clinical trials that have evaluated the efficacy and safety of intraoperative applications of topical corticosteroids for CRS. RESULTS A total of 21 articles, all of which highlight a variety of corticosteroid-infused products, including Propel corticosteroid-eluting stents, NasoPore, Merocel, SinuBand, calcium alginate, and bioresorbable gel-type products, are included for review. Propel stents are the only devices that have achieved level 1A evidence in terms of efficacy and have data to support their safety. The remaining products have shown mixed results in terms of efficacy and safety. CONCLUSION A wide range of techniques and technologies have been introduced to enhance the topical delivery of corticosteroids into the neosinuses after ESS for CRS. Regarding efficacy, there is level 1A evidence to support the use of Propel stents. Most of the remaining strategies show some degree of efficacy. Direct comparisons across the different strategies are limited owing to the varied uses of delivery vectors, corticosteroid choices, and doses of corticosteroids. Propel stents and SinuBand have sufficient data to support systemic and ocular safety, whereas the remaining products have limited data to support their safety.

Abstract
OBJECTIVES The purpose of this meta-analysis was to discuss the efficacy and safety of bioabsorbable steroid-impregnated implants following endoscopic sinus surgery (ESS) for chronic rhinosinusitis (CRS) patients. METHODS PubMed, Cochrane, EMBASE, Web of Science, and the Cochrane Central Register of Controlled Trials were comprehensively searched for studies comparing the experimental group (bioabsorbable steroid-impregnated implants) with the control group (bioabsorbable nonsteroid-impregnated implants). Lund-Kennedy scores, Perioperative Sinus Endoscopy (POSE) scores, polyp change, significant adhesion, middle turbinate lateralization, and adverse events were extracted from the final eligible studies. RevMan 5.3 software was used to analyze the data. RESULTS Eight randomized controlled trials were included in our analysis. The experimental group showed no significant differences from the control group in Lund-Kennedy scores (weighted mean difference (WMD) -0.40; 95% confidence interval [confidence interval (CI)] -1.05 to -0.62; P = 0.23). The experimental group had lower POSE scores compared with the control group, and there was a significant difference (WMD -1.88; 95% CI -2.32 to -1.43, P < 0.00001). The pooled results also demonstrated significant differences in polyp change, significant adhesion, and middle turbinate lateralization between the two groups. In addition, there was no significant difference with respect to adverse events between the two groups (odds ratio (OR) 0.38; 95% CI: 0.07 to 2.03; P = 0.26). CONCLUSION Bioabsorbable steroid-impregnated implants following ESS are effective in improving the endoscopic appearance of the healing process, and the safety profile appears to be favorable for the treatment of CRS patients.

Abstract
OBJECTIVE We employed a steroid-eluting, sinus-bioabsorbable device for local treatment after surgery for eosinophilic chronic rhinosinusitis (ECRS). One year later, we investigated its efficacy in suppressing recurrence and reducing the use of oral steroids. METHODS At one year after ECRS surgery, both 18 cases treated with a postoperative steroid-eluting, sinus-bioabsorbable device (Post-ST group) and 25 cases receiving conventional postoperative therapy (Post-Con group) showed significant improvement in the nasal symptoms (nasal obstruction, nasal discharge and olfactory dysfunction), CT score and threshold test (discrimination test). RESULTS The olfactory dysfunction, CT score and threshold test were significantly improved in the Post-ST group compared with the Post-Con group, but the polyp score was not. The mean total number of oral steroid tablets ingested during one year after surgery was 24.3±2.8 tablets in the Post-ST group, which was significant lower than the 36.3±3.7 tablets used in the Post-Con group. CONCLUSION The above results indicate that insertion of a steroid-eluting, sinus-bioabsorbable device after ECRS surgery can reduce the oral steroid intake while maintaining long-term suppression of disease recurrence.

Abstract
Topical therapy has become an important tool in the otolaryngologist's armamentarium for refractory chronic rhinosinusitis (CRS). Daily high-volume sinonasal saline irrigation and standard metered-dose topical nasal steroid therapy are supported by the most evidence. Nonstandard topical sinonasal steroid therapies are a potential option for refractory CRS. Current evidence recommends against the use of topical antifungal therapy and topical antibiotic therapy delivered using spray and nebulized techniques in routine cases of CRS. Stents are a new modality with preliminary data showing they are an option when traditional treatment has failed. Further research with long-term effects and outcomes studies for refractory CRS are needed.

Abstract
INTRODUCTION Management of the frontal sinus places great demands on the otolaryngologist. Given that the fronto-ethmoidal region is susceptible to recurrent inflammation, scarring, and stenosis, maintaining long-term patency of the frontal sinus is a difficult challenge. Oral and topical anti-inflammatory therapy, post-operative stenting, and 'home-brew' drug elution have been used for the treatment of the frontal sinus with mixed success. Recently an implant has been approved for post-operative placement into the frontal recess. This implant provides reliable and consistent steroid drug elution to address inflammation of the frontal recess secondary to chronic sinusitis. Areas covered: This review discusses the development and application of steroid eluting implants in the postoperative care of patients with chronic frontal sinusitis. All randomized controlled trials evaluating steroid eluting implants are discussed. Relevant supporting material discussing background, economics, safety are included. Expert commentary: Steroid eluting implants fulfill a unique niche in the treatment following frontal sinus surgery. They are shown to decrease the need for post-operative interventions and improve outcomes in patients with chronic sinusitis. There is significant potential for growth in the use of steroid eluting implants.

Abstract
INTRODUCTION Chronic rhinosinusitis (CRS) affects millions of patients worldwide. The disease is multifactorial with influences including anatomic factors, immunological disturbances, and altered sinonasal microbiome. Although oral medications are effective in controlling some symptoms, they are associated with side effects and long-term use is not ideal. Thus, topical therapies have emerged as an alternative delivery method for localized, high-concentration medication with less side effects. Areas covered: This is a review of the various topical therapies available or under investigation for the management of CRS. Common medications such as saline, steroids, and antimicrobials will be discussed. Furthermore, additives including manuka honey, xylitol, surfactant, N-chlorotaurine, Dead Sea salt, and sodium hyaluronate will be addressed. Innovations in topical therapies, such as drug-eluting biomaterials and photodynamic therapy, will also be reviewed. Expert opinion: Although topical therapies provide a high dose of active substance at the site of disease, their efficacy in CRS is not clear. Topical saline and intranasal steroids appear to consistently demonstrate therapeutic benefits. However, other topical medications require further investigation to determine long-term clinical efficacy and safety. A better understanding of their effects on the sinonasal mucociliary system is needed before they become the standard of care in CRS.

Abstract
Introduction Many different kinds of rhinologic biomaterials, both nonabsorbable and absorbable, have been developed over the years to improve outcomes following endoscopic sinus surgery (ESS) for patients with chronic rhinosinusitis. In particular, these products have been designed to prevent postoperative bleeding, optimize the wound healing process, and reduce inflammation. This review evaluates the most recent evidence on biomaterials used in rhinology, focusing on these outcomes after ESS. Data Sources MEDLINE, Scopus, Google Scholar, and Clinicaltrials.gov. Review Methods A primary literature search based on the listed databases was performed with combinatorial search terms. Studies were considered for review if they met a set of inclusion and exclusion criteria. Conclusions Some products have performed better than others in clinical trials, although significant heterogeneity among studies does not allow for selection of a clearly superior biomaterial. While nonabsorbable biomaterials are still effective in achieving certain outcomes, newer, absorbable substances may be just as effective and avoid the morbidity associated with nasal packing removal. Steroid-eluting biomaterials have shown promising early results in reducing inflammation and promoting wound healing. Implications for Practice Certain absorbable biomaterials, such as chitosan gel and fibrin glue, have performed well with respect to postoperative hemostasis and wound healing, although they do not address mucosal inflammation. Steroid delivery systems may play an increasingly important role in reducing disease recurrence after ESS, although more studies are needed to assess long-term outcomes.

Abstract
BACKGROUND Endoscopic sinus surgery (ESS) is considered a therapeutic option after failure of maximal medical therapy (MMT) for chronic rhinosinusitis (CRS). There is currently no consensus on the definition of MMT. The objective of this systematic review is to describe the various MMT criteria employed prior to considering ESS. METHODS A systematic review was performed using the 2009 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Inclusion criteria were adults with CRS based on guideline diagnostic criteria, enrolled to undergo ESS, and study publication within the last 5 years (January 1, 2009, to December 30, 2014). Studies were excluded if the study population included non-CRS indications for ESS. Primary outcome was the MMT criteria employed prior to considering a patient a candidate for ESS. A subgroup analysis was performed based on polyp status. RESULTS Of 387 reviewed studies, 21% reported MMT criteria. When reported, criteria included topical nasal corticosteroids (91% of studies) for a mean of 8 ± 8 weeks, oral antibiotics (89%) for 23 ± 8 days, systemic corticosteroids (61%) for 18 ± 12 days, saline irrigations (39%), oral antihistamines (11%), oral mucolytics (10%), and topical/oral decongestants (10%). CONCLUSION A minority of studies report MMT criteria used as the indication for ESS. When reported, the majority included an 8-week course of topical intranasal corticosteroids and 3-week course of oral antibiotics. Use of systemic corticosteroids did not differ based on polyp status. Because of variation in current MMT criteria, there is a need to develop standardized indications for ESS that will work to improve the appropriateness of care for patients with.

Abstract
The innate immune system and its complex interplay with the adaptive immune system are increasingly being recognized as important factors in the pathogenesis of chronic rhinosinusitis (CRS). Adaptive immune components, including resident and inflammatory cells, and their associated mediators, have been the subject of most research in CRS. For this reason, theories of CRS pathogenesis have involved the concept that inflammation, rather than infection, is the dominant etiologic factor in CRS. Therefore, glucocorticoids are increasingly used to treat CRS. This review will outline our current knowledge of action mode of glucocorticoids in CRS.

Abstract
OBJECTIVES/HYPOTHESIS The frontal sinus is one of the most anatomically complex and inaccessible of the paranasal sinuses. As a result, surgeons have continually tried to improve surgical management of the frontal sinus. The senior author (c.w.g.) shares 50 years of experience managing the frontal sinus. DATA SOURCES PubMed literature search. REVIEW METHODS Review of the literature regarding landmark innovations in frontal sinus surgery. RESULTS Open approaches established that the frontal sinus is accessible, and in certain circumstances, such as with large osteoma or papilloma, are still required. The endoscope changed the surgical landscape and allowed for greater finesse and decreased morbidity. Sinus balloon dilation is the newest change in frontal sinus management and shows promise in properly selected cases. CONCLUSION Surgery of the frontal sinus continues to evolve and improve. Although there are new techniques, the older techniques are still pertinent.

Abstract
BACKGROUND Functional endoscopic sinus surgery (FESS) has become a well-established approach for treating patients with chronic rhinosinusitis (CRS) refractory to medical management. However, the surgical outcome may be compromised by postoperative inflammation, polyposis and adhesions, which often require subsequent intervention. Bioabsorbable, steroid-eluting sinus stents are inserted into the nose, sinuses or both following surgery to prevent stenosis of the sinus openings during the postoperative healing period. The slow release of corticosteroid aims to decrease mucosal oedema and expedite wound healing. Whether a steroid-eluting stent offers any beneficial effects in terms of improving sinonasal symptoms has not been systematically reviewed. OBJECTIVES To assess the safety and efficacy of steroid-eluting sinus stent placement in CRS patients after FESS. SEARCH METHODS The Cochrane Ear, Nose and Throat Disorders Group (CENTDG) Trials Search Co-ordinator searched the CENTDG Trials Register; Central Register of Controlled Trials (CENTRAL 2015, Issue 4); PubMed; EMBASE; CINAHL; Web of Science; Clinicaltrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the search was 14 May 2015. SELECTION CRITERIA We included all randomised controlled trials (RCTs) comparing steroid-eluting sinus stents with non-steroid-eluting sinus stents, nasal packing or no treatment in adult CRS patients undergoing FESS. DATA COLLECTION AND ANALYSIS We used the standard methodological procedures expected by The Cochrane Collaboration. MAIN RESULTS We identified no RCTs that met our inclusion criteria. Among the 159 records retrieved using our search strategy, 21 trials had the potential to be included given that they had tested sinus stents, spacers and packing materials for patients with CRS undergoing FESS. However, we excluded these trials from the review because they met some but not all of the inclusion criteria. AUTHORS' CONCLUSIONS We are unable to provide evidence to establish whether steroid-eluting sinus stents have potential advantages and disadvantages for patients with CRS undergoing FESS. Future, high-quality RCTs are needed to assess whether or not steroid-eluting sinus stents confer any beneficial effects, over those of surgery alone, when compared to non-steroid sinus stents.

Abstract
OBJECTIVE Steroid-eluting spacers can improve local drug delivery immediately following endoscopic sinus surgery and reduce the recurrence of inflammation warranting systemic corticosteroids. For chronic rhinosinusitis with nasal polyposis, the need for systemic corticosteroids immediately following endoscopic sinus surgery when using a steroid-eluting spacer has not been studied. STUDY DESIGN A randomized, double-blind, placebo-controlled trial. SETTING Academic rhinology practice. SUBJECTS AND METHODS Chronic rhinosinusitis patients with nasal polyposis who failed medical therapy and elected endoscopic sinus surgery were enrolled. Patients were randomized into either the treatment arm (postoperative prednisone 30 mg daily × 7 days; n = 18) or placebo arm (postoperative placebo pill daily × 7 days; n = 18). Outcomes were evaluated at 1 week, 3 weeks, and 2 months postoperatively. Primary outcome was endoscopic grading at postoperative month 2 using the Lund-Kennedy system. Secondary outcome included disease-specific quality of life using the Sinonasal Outcome Test (SNOT-22) survey. Patient enrollment occurred from January 2012 through February 2013 (NCT01564355). RESULTS Both arms received significant improvement in endoscopic grading and disease-specific quality of life from baseline compared to 2-month follow-up (P < .001). There were no significant differences in mean endoscopic scores between the postoperative prednisone and control groups at 1 week (P = .715), 3 weeks (P = .883), or 2 months (P = .343). There were no significant differences in SNOT-22 scores between groups at all follow-up points (all P > .119). CONCLUSION Minimizing systemic corticosteroid use in patients with chronic rhinosinusitis with nasal polyposis may avoid adverse events. Results from this study suggest that postoperative systemic corticosteroids immediately following endoscopic sinus surgery may not provide improved outcomes when utilizing a steroid-eluting spacer.

Abstract
Objective The aim of this study was to find out the efficacy of a polyvinyl alcohol (PVA) sponge (Merocel Kennedy; Medtronic Xomed, Jacksonville, Florida) sinus pack soaked with levobupivacaine hydrochloride to control postoperative pain and analgesic need following functional endoscopic sinus surgery (FESS). Study Design The study was designed as a prospective, double-blind, randomized, controlled study. Forty-one patients who underwent FESS were included in the analysis. Setting A tertiary referral hospital in Turkey. Materials and Methods Patients who underwent FESS were divided into 2 groups. The PVA sponge sinus packs were soaked with 5 mL of levobupivacaine hydrochloride (chirocaine 25 mg/10 mL; Abbott, Nycomed Pharma AS, Elverum, Norway) in group I and with 5 mL of saline in group II. Main Outcome Measures Postoperative pain levels were recorded using a visual analog scale (VAS score, 0-100) at 30 minutes and 1, 2, 8, 12, and 24 hours. Results There were no statistically significant differences between groups regarding age, sex, and American Society of Anesthesiologists status. Postoperative VAS values at 30 minutes and 1, 2, 8, 12, and 24 hours were significantly lower in group I than in group II ( P < .05). Supplemental analgesia amount was significantly lower in group I than in group II ( P = .003). Conclusion Using levobupivacaine-soaked PVA sponge sinus packs after FESS is an effective, easy, and quick method to control postoperative pain, and it improves patient comfort and tolerability.

Abstract
BACKGROUND Middle meatal (MM) spacers may reduce adhesions following endoscopic sinus surgery (ESS). However, there is no consensus as to which materials and adjuncts are the most effective for this purpose. The primary objective of this study was to examine the effectiveness of absorbable spacers (AS) vs nonabsorbable spacers (NAS) in reducing adhesions following ESS for chronic sinusitis. Secondarily, we assessed steroidal vs nonsteroidal MM spacers in reducing adhesions. METHODS Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic review of randomized controlled trials (RCTs) was conducted and a meta-analysis on relevant outcome data was performed. Electronic search was done using OVID MEDLINE, EMBASE, Cochrane Central register of Controlled Trials, and Web of Science. Independent data extraction and evaluation was conducted. RESULTS For our primary objective, 6 RCTs were included in the systematic review. A pooled estimate of relevant trials revealed a nonsignificant trend favoring AS in reducing adhesion formation compared to NAS (Relative Risk (RR), 0.40; 95% confidence interval [CI], 0.15-1.03). This trend was not apparent if NAS are left for greater than 48 hours after ESS. For our secondary objective, we identified 5 RCTs that compared steroidal vs nonsteroidal spacers. Although a pooled analysis could not be achieved due to inconsistent reporting of MM adhesions, 2 studies demonstrated significantly less adhesions in the steroidal spacer group. CONCLUSION Comparison between NAS and AS showed that there was no significant difference in adhesion rates if NAS are used for at least 48 hours after surgery. Steroidal spacers may reduce adhesions, but more consistent data reporting is required for meta-analysis.
