Abstract
Background Adhesion formation, sinus ostial narrowing, and presence of pathogenic bacteria are associated with poor outcomes following endoscopic sinus surgery (ESS) for chronic rhinosinusitis. Chitogel has been shown to improve wound healing, restore a healthier microbiome, and reduce post-operative infections post ESS. Deferiprone has antibacterial properties and has been shown to reduce adhesion formation. The aim of the study was to assess whether the addition of low concentration deferiprone to Chitogel further improves surgical outcomes following ESS compared with Chitogel alone. Methods In this double-blinded trial, 45 patients undergoing ESS were prospectively recruited. At the end of the surgery, patients were randomised to receive Chitogel alone, Chitogel with 1 mM of deferiprone, or Chitogel with 5 mM of deferiprone to one side of the sinuses (allowing the other side to serve as control). Patients underwent routine follow-ups with symptom questionnaires and nasoendoscopies performed at 2, 6, and 12 weeks post-operatively. Sinus ostial measurements, microbiology, and microbiome swabs from bilateral middle meatuses were collected intraoperatively and at 12 weeks post-operatively. Results A significant improvement in the endoscopic appearance of the sinuses and frontal ostial patency was noted at 12 weeks post-operatively (p < 0.05) in all three treatment groups compared with the control. There was no significant difference noted between patients who received Chitogel alone and those who received Chitogel with 1 or 5 mM deferiprone. Conclusion Chitogel alone, Chitogel with 1 mM deferiprone, and Chitogel with 5 mM deferiprone used following ESS led to a significant improvement in endoscopic appearance of the sinuses and frontal ostial preservation at 12 weeks post-operatively. No significant difference was found with the addition of deferiprone to Chitogel.

Abstract
BACKGROUND Sphenoid and frontal sinuses have narrow ostia and are prone to stenosis. However, their relative rates of patency are not well established, and descriptive rates of sphenoid stenosis have never been reported. The objective is to measure the patency of the sphenoid and frontal sinus ostia postoperatively. METHODS A prospective multi-institutional cohort study was performed. Ostial patency was measured at surgery and 3 and 6 months postoperatively. Pertinent clinical history such as the presence of nasal polyps and prior history of ESS as well as the use of steroid eluting stents were recorded. Overall stenosis rates were calculated for both the sphenoid and frontal sinuses, and Wilcoxon-Signed Rank Test was used to compare intraoperative and postoperative ostial areas. Factorial Analysis of Variance (ANOVA) was performed to determine effects of 5 clinical factors. RESULTS Fifty patients were included. The mean sphenoid sinus ostial area decreased 42.2% in size from baseline to 3 months postoperatively (T0 55.2 ± 28.7 mm vs T3 m 31.8 ± 25.5 mm, P < .001). The mean frontal sinus ostial area decreased 39.8% in size from baseline to 3 months postoperatively (T0 33.7 ± 17.2 mm vs T3 m 19.9 ± 15.1 mm, P < .001). Neither the sphenoid nor the frontal sinus ostial patency demonstrated statistically significant change from 3 to 6 months postoperatively. CONCLUSION Both sphenoid and frontal sinus ostia routinely narrow postoperatively, predominately from baseline to 3 months. These findings can serve as a reference for both clinical outcomes and future studies of these surgeries.

Abstract
BACKGROUND The frontal sinus and its drainage pathway are difficult spaces to navigate surgically. The complexity of the frontal recess anatomy as well as inflammatory factors may influence outcomes of endoscopic frontal sinusotomy. It is not clear which factors are more important in determining post-operative frontal ostium patency. OBJECTIVE The objective is to investigate whether the distribution of fronto-ethmoidal cells, frontal recess dimensions and sinonasal inflammation predict frontal ostium patency at 1- and 2-years after endoscopic frontal sinusotomy. METHODS A retrospective review of 94 chronic rhinosinusitis patients (185 sides) who had undergone endoscopic frontal sinusotomies between 2015 and 2019 was conducted. Computed tomography was used to evaluate the type of fronto-ethmoidal cells present and determine the dimensions of the frontal recess. The International Classification of the Radiological Complexity of frontal recess and frontal sinus was used to grade the complexity of frontal recess anatomy. Mucosal inflammation was graded according to a structured histopathology report. Frontal ostium patency at 1- and 2-years post-operatively was recorded. RESULTS The frontal ostium patency rates were 80.9% and 73.4% at 1- and 2-years respectively. Eosinophilic predominance (adjusted OR 3.5, 95% CI 1.6-8.0, p = 0.003) and mucosal ulceration on histology (adjusted OR 4.5, 95% CI 1.1-17.9, p = 0.033) predicted ostial stenosis at 1 year. Smoking (adjusted OR 7.6, 95% CI 2.4-24.7, p = 0.001), aspirin exacerbated respiratory disease (AERD) (adjusted OR 7.6, 95% CI 1.9-30.1, p = 0.004) and histological findings of severe inflammation (adjusted OR 8.9, 95% CI 1.9-41.2, p = 0.005) were independent predictors of ostial stenosis at 2 years. Frontal cell patterns, frontal recess dimensions and frontal recess complexity did not predict frontal ostium stenosis at both 1- and 2-years post-operatively. CONCLUSION Post-operative control of sinonasal inflammation is important in maintaining frontal ostium patency, regardless of frontal cell patterns or frontal recess dimensions.

Abstract
BACKGROUND Postoperative infections following endoscopic sinus surgery (ESS) impair wound healing and lead to poor outcomes. The aim of this study is to assess the effectiveness of Chitogel to reduce postoperative infections and restore a healthy microbiome following ESS. METHODS In this double-blinded randomized control trial, 25 patients undergoing ESS were prospectively recruited. At the end of surgery, patients were randomized to receive Chitogel to one side of the sinuses (allowing the other side to serve as control). Patients underwent routine follow-up with nasoendoscopies performed at 2, 6, and 12 weeks postoperatively. Sinus ostial measurements, microbiology, and microbiome swabs from bilateral sides were collected intraoperatively and at 12 weeks postoperatively. Additional swabs were collected if infection was present. RESULTS Improved endoscopic appearance of the sinuses (p = 0.03) and ostial patency were noted on the Chitogel side compared with control at 12 weeks (p < 0.001). A significant decrease in infections on the Chitogel side (12.0%) compared with control (52.0%) (p = 0.005) was evident. Following the use of Chitogel, there was a significant increase in the combined relative abundance of commensals Corynebacterium and Cutibacterium (Propionibacterium) from 30.15% at baseline to 46.62% at 12 weeks compared with control (47.18% to 40.79%) (p.adj = 0.01). CONCLUSION Chitogel significantly improved both the nasoendoscopic appearance of the sinuses and sinus ostial patency at 12 weeks postoperatively. Chitogel used following ESS helps restore an improved microbiome resulting in an increase in the relative abundance of commensals Corynebacterium and Cutibacterium (Propionibacterium). A significant decrease in postoperative infections was noted following use of Chitogel.

Abstract
Functional endoscopic sinus surgery (FESS) has become one of the most common surgical techniques performed by otolaryngologists with significant data demonstrating its efficacy in managing patients with chronic rhinosinusitis (CRS). However, despite this initial success, patients may continue to present with recurrent symptoms and approximately 10-15% of them will require revision surgery. Failure of FESS may have many different causes which include inappropriate patient selection and preparation, comorbidities like cystic fibrosis and Samter's triad, insufficient surgical skills or anatomical variations that have not been addressed adequately. Two inverse European techniques were introduced in the 1980s. The one promoted by Messer-klinger, who practiced the anterior-to-posterior approach, another one, developed by Wigand who performed posterior-to-anterior dissection, opens the sphenoid ostium or removes the anterior wall of the sphenoid sinus and ends with a total ethmoidectomy. Hereby in RESS we start dissection in posterior-to-anterior fashion by following a structured approach in the identification of the fixed landmarks to allow quick and easy orientation to the skull base and medial orbital wall to avoid the complications.

[PMID: 35868110 DOI: 10.1016/j.ijporl.2022.111240] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2022] [Revised: 07/07/2022] [Accepted: 07/11/2022] [Indexed: 10/17/2022]
Abstract
BACKGROUND Choanal Atresia is a congenital condition that presents as a blockage from the nasal cavity to the nasopharynx. According to the German statistical Institute (Statistisches Bundesamt), the incidence in Germany in 2018 reached 2.74 in 10,000 live births. It can present unilaterally or bilaterally. As newborns are obligate nasal breathers, management of bilateral atresia has to be performed early after birth. As for unilateral atresia, the optimal age for treatment was determined to be between 6 and 12 months in a recently published consensus. OBJECTIVE The main purpose of this study is to characterize the patients treated for choanal atresia in the Department of Otorhinolaryngology and Head and Neck Surgery at a tertiary hospital in the south of Germany and, based in the demographic characteristics as well as intra- and post-operative treatment, to identify factors for success or failure of the surgery. A secondary goal was to describe the complications in the use of stents and analyse its influence in the results. MATERIAL AND METHODS The cohort-based observational study included 29 patients, with a minimum follow up of one year, who underwent surgical endoscopic correction of both unilateral and bilateral choanal atresia from 2003 to 2020. Analysis of the demographics, intraoperative, and postoperative treatment, and their results, was performed. Multinomial logistic regression was applied for categorical values. Comparisons were performed using Fischer/chi-square test where applicable. A significance level of 0.05 was reached. RESULTS The population was comprised of 34.5% male and 65.5% female patients. The age varied from 2 days to 20 years old, with a mean of 4.98 years and Standard Deviation (SD) 6.88. The weight of the patients varied between 1.4 kg and 85.0 kg, with a mean of 19.36 and SD 22.58. Unilateral choanal atresia was present in 58.6%, and bilateral in 41.4%. Out of this population, 48.3% presented with associated malformations. The number of procedures per patient performed in general anesthesia varied from 1 to 9, with a mean of 2.52 and SD of 2.23: statistically higher for patients presenting with bilateral atresia with a p value of 0.001*. 20 patients had a tube (Vygon, France) placed at first surgery. In 5 patients, a drug-eluting stent (Propel mini (R); Intersect ENT, USA) was applied intraoperatively, without complications. In unilateral choanal atresia, surgical and functional success was attained in 88.2% of the cases. In bilateral cases, it reached 75%. We observed a strong linear relationship between the weight of the patient and the size of the choana perioperatively: R quadrat 0.596, which may be a determinant factor in the wound healing. Weight, age, and concomitant pathology achieved statistical significance in the logistic regression model (p respectively 0.001*, 0.001* and 0.010*), which shows its influence in the result of the surgery. In particular, weight inferior to 3 kg (p 0.001*, chi-square test) at the time of the first surgery is a determinant demographic factor for need of revision in order to achieve patency. There were no major complications associated with the use of a stent, besides its dislodgement. We could not infer an implication of its use on the success of the surgery in the present cohort. LIMITATIONS for this study were the small size of the cohort and non-standardized records for some variables. CONCLUSIONS Younger patients presenting with low weight and concomitant pathology have worse results after surgical endoscopic treatment of choanal atresia, revealing these characteristics to be determinant for success. The size of the neochoana is related to the weight of the patient, which is a limiting factor. In particular, patients under 3 kg had to undergo more procedures in order to achieve patency. The implication of the use of locally applied medication needs to be further studied.

Abstract
The Draf Ⅲ procedure involves the creation of a common frontal sinus cavity. The most common indication for the Draf Ⅲ procedure is chronic rhinosinusitis of the frontal sinuses despite the failure of more conservative interventions such as bilateral Draf Ⅱa procedures. Primary Draf Ⅲ may be indicated in patients with a high risk of failures such as those with severe polyposis and those with a frontal sinus opening less than 4 mm on computed tomography imaging. Other indications for the Draf Ⅲ include access for tumor removal and repair of traumatic fractures of the frontal sinus. The “inside‐out” Draf Ⅲ procedure is the standard approach when the frontal recess anterior–posterior diameter is wide enough for instrument access, usually larger than 4–5 mm. The “outside‐in” Draf Ⅲ procedure can be done when the frontal recess is too narrow to safely accommodate instruments. Regular follow‐up with debridement should be done to prevent neo‐ostium stenosis.

Abstract
Background: Lateral pathologies of the frontal sinus are difficult to visualize and treat with classical endoscopic sinus surgery (ESS) using rigid endoscopes and instruments. Hence, they often require extended endoscopic or external approaches. Methods and Results: We describe the advantages of using interventional flexible bronchoscopy in frontal ESS without extended approaches in 2 illustrated cases: (1) A fungus ball in the frontal sinus with a frontoethmoidal cell. The flexible bronchoscope allowed treatment of all recesses of the frontal sinuses and the opening of a frontoethmoidal cell through a Draf IIa. (2) A revision surgery with a frontoethmoidal cell obstructing drainage pathway was successfully treated with this same technique. Patients did not experience complications or recurrent symptomatology after, respectively, 4 and 15 months of follow-up. Conclusion: Flexible bronchoscopy allows a good visualization and treatment of lateral frontal sinus pathologies through limited endoscopic approaches. Through-the-scope instruments permit the resection of frontoethmoidal cells.

Abstract
OBJECTIVES The study aimed to assess the factors affecting the frontal sinus patency after endoscopic frontal sinusotomy. DESIGN A prospective cohort study. SETTING Tertiary centre hospital. MAIN OUTCOME MEASURES Fifty patients with refractory chronic frontal sinusitis (83 operated frontal sinuses) had frontal sinusotomy and followed up for six months. Multiple operative factors were included the type of the procedure, intraoperative sinus findings, degree of mucosal preservation and middle turbinate stability. Other factors were also assessed, including smoking, the presence of allergic rhinitis, asthma, gastroesophageal reflux and other associated medical comorbidities. RESULTS The sinus patency success rate was 75.9%. There was a significant difference regarding the intraoperative anteroposterior sinus ostium diameter (5.36 ± 1.45 mm vs 8.88 ± 2.38 mm, P-value: .001* in the failed group and the success group, respectively). There was a significant association between the patency outcome and the presence of associated medical comorbidities (P-value: .001*), the presence of allergic rhinitis (P-value: .001*), the degree of sinus mucosal preservation (P-value: .012*) and the degree of middle turbinate stability (P-value: .001*). The multivariate analysis showed that the intraoperative anteroposterior diameter of the sinus ostium, middle turbinate stability and presence of allergic rhinitis were significant predictors (P-value: .012*, .042* and .013*, respectively). CONCLUSION Sinuses with anteroposterior ostium diameters less than 5.36 mm are more susceptible to restenosis. The flail middle turbinate increases the risk of postoperative middle meatus synechia and frontal sinus patency failure. The presence of allergic rhinitis has a negative impact on the patency outcome.

Abstract
OBJECTIVES This study aimed to compare the effects of middle turbinate resection vs bolgerization on the incidence of middle meatus synechia and their prognostic value on the patency outcomes after frontal sinusotomy. DESIGN A randomised controlled study. SETTING Tertiary centre hospital. MAIN OUTCOME MEASURES Thirty-eight patients undergoing bilateral frontal sinusotomy for chronic frontal sinusitis were included. Partial middle turbinate resection was alternated with bolgerization in both nasal cavities of every patient. The Lund-Kennedy endoscopic scores (LKESs) for both sides were compared at the first, third and sixth months postoperatively. Middle meatus synechia was assessed using the visual analogue score (VAS). Sinus patency was assessed at the end of the sixth month using a 70° nasal endoscope. RESULTS The sinus patency outcome was significantly higher in the resected group (34\38) than the bolgerized group (26\38), (P = .047*). The VAS scores suggested that the middle turbinate bolgerization group showed a significantly higher incidence of middle meatal synechia than the partial middle turbinate resection group (4.47 ± 2.617 vs 3.29 ± 2.301; P = .040*). CONCLUSION Middle turbinate resection showed more favourable results than bolgerization concerning the sinus patency outcome after frontal sinusotomy. It also showed a lower incidence of middle meatus synechia postoperatively.

Abstract
OBJECTIVES The study aimed to assess the association between the preoperative CT findings and the patency outcome of the frontal sinus after endoscopic frontal sinusotomy in the early follow-up period. DESIGN A prospective cohort study. SETTING Tertiary hospital centre. MAIN OUTCOME MEASURES The study measures the association between the frontal sinusotomy outcome and the standard preoperative radiological scores, including Harvard, Kennedy and Lund-Mackay. It also measures the impact of the degree of sinus mucosal thickness on the outcome. Furthermore, it measures the effect of the anteroposterior lengths of both the frontal sinus ostium and the frontal recess on postoperative frontal sinus patency. RESULTS Harvard, Kennedy and modified Lund-Mackay scores showed no evidence of association with the frontal sinusotomy patency outcome (P-values .397, .487 and .501), respectively. Still, the Lund-Mackay score showed a negative correlation with symptom improvement. Sinuses with a high-grade mucosal thickness on CT scan were associated with high failure rates (P-value: .009*). The anteroposterior length of the frontal sinus ostium significantly affects the outcome (P-value: .001*). In contrast, there was no association between the anteroposterior length of the frontal recess and the outcome (P-value: .965). CONCLUSION The Harvard, Kennedy and Lund-Mackay scores could not predict the frontal sinusotomy patency outcome. Failed cases were associated with advanced degrees of mucosal pathology in the preoperative CT scan. Sinuses ostia with anteroposterior diameters less than 5.36 mm showed more susceptibility for sinus restenosis postoperatively. The variability of the anteroposterior length of the frontal recess did not affect the surgical outcome.

Abstract
The current literature lacks strong guidelines regarding surgical management of patients with aspirin-exacerbated respiratory disease (AERD), who present with the clinical triad of chronic rhinosinusitis with nasal polyposis (CRSwNP), bronchial asthma, and aspirin/nonsteroidal anti-inflammatory drug intolerance. To further define the effectiveness of sinus surgery in treating AERD patients, this review article discusses current evidence regarding outcomes associated with more extensive surgery, the benefits of frontal sinus surgery on polyposis, and the role of Draf III intervention. Numerous studies suggest that Draf III frontal sinusotomy may be an efficacious early intervention due to increased neo-ostial patency and subsequent distribution of topical therapies. Future studies that further investigate the efficacy and safety of extensive surgery in AERD patients are warranted.

Abstract
INTRODUCTION Frontal sinus surgery remains challenging to manage because of its complex anatomy and narrow outflow tract. A number of studies suggest the success of frontal sinus stenting to reduce postoperative complications in endoscopic frontal sinus surgery. However, failure and complications of frontal sinus stenting may occur. METHOD We present a case of frontal sinus stenting with migration of the stent and erosion of the lamina papyracea together with a granulomatous reaction around the stent. PubMed and Medline search was also conducted to study the current evidence on frontal sinus stenting benefits and complications. RESULTS Still there are no guidelines or universally accepted indications for the use of frontal sinus stenting in the literature. A limited number of studies suggest the success of frontal sinus stenting to reduce postoperative stenosis in endoscopic frontal sinus surgery. However, failure and complications of frontal sinus stenting may occur. Infection, pain, edema, and stent obstruction may also occur. Our case report also highlights the potential of orbital complications as well as the consequences of inducing a granulomatous reaction. CONCLUSION The value of frontal sinus stenting is still a subject of debate. Complications of frontal sinus stenting are not uncommon and thus necessitate regular follow-up.

Abstract
Purpose Draf drainage is the standard treatment procedure for frontal sinus diseases. In this procedure, rigid angled endoscopes and rigid curved instruments are used. However, laterally located pathologies in the frontal sinus cannot be reached with rigid instrumentation. In order to assist surgeons with such complicated cases, we propose a novel handheld flexible manipulator system. Methods A cross section of 3 mm × 4.6 mm enables transnasal guiding of a flexible endoscope with 1.4 mm diameter and a standard flexible surgical instrument with up to 1.8 mm diameter into the frontal sinus with increased reachability. The developed system consists of an electrical discharge-machined flexure hinge-based nitinol manipulator arm and a purely mechanical handheld control unit. The corresponding control unit enables upward and left–right bending of the manipulator arm, translation, rolling, actuation and also quick exchange of the surgical instrument. In order to verify the fulfillment of performance requirements, tests regarding reachability and payload capacity were conducted. Results Reachability tests showed that the manipulator arm can be inserted into the frontal sinus and reach its lateral regions following a Draf IIa procedure. The system can exert forces of at least 2 N in the vertical direction and 1 N in the lateral direction which is sufficient for manipulation of frontal sinus pathologies.
Conclusion Considering the fact that the anatomical requirements of the frontal sinus are not addressed satisfactorily in the development of prospective flexible instruments, the proposed system shows great potential in terms of therapeutic use owing to its small cross section and dexterity.

Abstract
BACKGROUND Chronic rhinosinusitis (CRS) causes severe symptoms that lead to poor quality of life. When optimal medical therapy does not improve CRS symptoms, then endoscopic sinus surgery (ESS) can be used in patients with persistent symptoms and radiographic evidence of CRS to improve patients' symptoms and quality of life. Despite appropriate and complete sinus surgery, there can be issues after sinus surgery such as synechiae formation and recurrence of polyps in certain CRS patients that can decrease long-term outcomes. Corticosteroids are used to decrease postoperative scarring and edema as well as prevent recurrence of nasal polyp formation after sinus surgery. However, the use of oral or systemic steroid can lead to serious short-term and long-term complications. Therefore, a safer alternative would be the topical delivery of steroid via steroid-eluting sinus implants. METHODS A literature review was performed to identify clinical studies evaluating steroid-eluting implants. Two forms of steroid-eluting implants were identified, Propel family products and Sinuva. The research findings from clinical studies using various steroid-eluting sinus implants are reviewed and discussed. RESULTS Four prospective randomized clinical studies were identified for the Propel family products. Two prospective randomized clinical studies were identified for Sinuva. The results from the clinical studies showed that the use of the various steroid-eluting sinus implants can improve postoperative results after ESS as well as treat the recurrence of nasal polyps after sinus surgery without the need for additional sinus surgery. CONCLUSION The novel steroid-eluting implants appear to be beneficial for CRS patients immediately post-operatively as well as for nasal polyps patients. Interestingly, these implants could be used as a substitute for the beneficial effect of systemic steroid use for CRS patients.

Abstract
Frontal sinus stenting is widely used with the goal of maintaining nasofrontal duct patency after sinus surgery. The general recommendation is to leave stents in place for 6 months; however, prolonged stenting up to 6 years has been reported with no complication. We present the first reported case of frontal sinus posterior table and skull base erosion following prolonged frontal sinus stenting. A 57-year-old female presented with chronic sinusitis and nasal obstruction. Imaging revealed pansinusitis with retained stents in each frontal sinus that were placed 8 years prior. On the right, there was an area of skull base erosion at the tip of the stent. The patient underwent functional endoscopic sinus surgery with polypectomy. The stents were removed, revealing posterior table erosion on the right side but intact mucosa. Two months after surgery, there were no signs or symptoms of cerebrospinal fluid leak or other complications. Recent literature has suggested that prolonged stenting is safe; however, this case highlights a complication with potentially serious outcomes that can result from prolonged stenting. We recommend stent removal once stable nasofrontal duct patency has been achieved. If prolonged stenting is utilized, patients should be closely monitored and consideration should be given to periodic imaging to evaluate stent position.

Abstract
Objectives Frontal sinus anatomy is complex, and multiple variations of ethmoid pneumatization have been described that affect the frontal outflow tract. In addition, the lumen proper of the frontal sinus may exist as 2 separate parallel cavities that share an ipsilateral outflow tract. This variant has not been previously described and may have implications for surgical management. Study Design Case series. Setting Tertiary rhinology practice. Subjects and Methods Cases with radiographic and intraoperative findings of separate parallel tracts within a unilateral frontal sinus were identified from a consecutive series of 186 patients who underwent endoscopic sinus surgery between May 2015 and July 2016. Data were recorded including sinusitis phenotype, coexisting frontal cells, and extent of surgery. Results Ten patients (5.4%) were identified with computed tomography scans demonstrating bifurcation of the frontal sinus into distinct medial and lateral lumens. All cases were treated with Draf 2a or 2b frontal sinusotomy with partial removal of the common wall to create a unified ipsilateral frontal ostium. Eleven sides had a coexisting ipsilateral agger nasi cell, 7 had a supra-agger cell, 8 had a suprabullar cell, and 1 had a frontal septal cell. There were no significant complications. Conclusion The bifurcated frontal sinus is an anatomic variant that the surgeon should recognize to optimize surgical outcomes. Failure to do so may result in incomplete clearance of the sinus and residual disease. The bifurcated sinus may occur with other types of frontal sinus cells and may be safely treated with endoscopic techniques.

Abstract
Background Bioabsorbable steroid‐releasing implants (mometasone furoate, 370 μg) are effective for improving postsurgical outcomes in the frontal sinus ostia (FSO). In this study we evaluated the effect of these implants on frontal outcomes in various patient subgroups with chronic rhinosinusitis (CRS) using pooled data from 2 randomized, controlled trials (RCTs). Methods A total of 160 subjects were enrolled in 2 RCTs. After surgery, subjects were randomized to receive an implant in 1 FSO with the contralateral side as control. Data through day 90 from the 2 studies were pooled and subgroup analyses were performed. Results At day 30, relative to controls, steroid‐releasing implants significantly reduced the need for postoperative interventions by 46.8% (95% confidence interval [CI], −60.7 to −27.9), for surgical interventions by 51.2% (95% CI, −68.2 to −25.2), and for oral steroid interventions by 37.2% (95% CI, −54.6 to −13.1) in the pooled data set. At day 90, statistically significant reductions (p < 0.05) in the need for postoperative interventions (relative reduction [RR], 30.2%), restenosis/occlusion rate (RR, 31.7%), and inflammation score (absolute difference, −6.0), and increase in estimated FSO diameter (absolute difference, 1 mm), favoring the treated side, were observed. Subgroup analyses of the pooled data showed statistically significant improvements (p < 0.05) at day 90 in restenosis/occlusion rate, and estimated FSO diameter, favoring the treated side across subgroups, with no statistically significant subgroup‐by‐treatment interactions. Conclusion Bioabsorbable steroid‐releasing sinus implants improve outcomes of frontal sinus surgery through 90 days, irrespective of asthma status, previous endoscopic sinus surgery, extent of surgery, extent of polyps, or Lund‐Mackay computed tomography stage in the FSO.

Abstract
PURPOSE OF REVIEW Historically, the common frontal sinusotomy has been reserved only for salvage frontal sinus surgery in patients with severely recalcitrant inflammatory sinus disease. By understanding the pathophysiology of inflammatory sinus disease and the long-term role of topical medication in their treatment, the indications for Draf3 have expanded. RECENT FINDINGS A major therapeutic impact from endoscopic sinus surgery for inflammatory sinus disease is imparted by allowing sinus access to topical therapies to work. Although traditionally, the Draf3 frontal sinus procedure has been reserved for revision surgery in severe cases, advancements in technology, instrumentation, and techniques has allowed the Draf3 to evolve to efficient and safe procedure, often applied primarily in select patients. There is evidence to support the indication for Draf3 in primary surgery for severe cases. SUMMARY In inflammatory sinus disease, the goal of endoscopic sinus surgery is to convert the complex and limited frontal sinus outflow tracts into a simple common cavity. This allows for local, topical anti-inflammatory treatments to control the disease. When patients have broader inflammatory airway disease and asthma, the Draf3, as part of a neo-sinus cavity, is commonly applied early in surgical care.

Abstract
BACKGROUND The endoscopic modified Lothrop (Draf-III) surgery has improved treatment of recalcitrant frontal sinus disease, with favorable safety and long-term results. However, the short-term clinical and quality-of-life morbidity after Draf-III relative to less-extensive procedures has yet to be investigated. OBJECTIVE To evaluate the surgical and quality-of-life outcomes, including the burden of follow-up care, in patients who underwent endoscopic modified Lothrop (Draf-III), and compared these results with a less-extensive intervention, the endoscopic frontal sinusotomy (Draf-IIa). METHODS A retrospective review of early (<8 weeks) postoperative recovery of patients who underwent Draf-III (2014 to 2016) for chronic rhinosinusitis was conducted and compared with age and radiographically matched Draf-IIa controls. Primary outcomes included perioperative complications, the number of postoperative clinic visits, debridements, and steroid and antibiotic therapy days. Secondary outcomes included the change in the 22-item Sino-Nasal Outcome Test (SNOT-22) scores and/or subscores (domains). RESULTS Thirty-eight patients (19 Draf-III, 19 Draf-IIa) were included. Patients who underwent Draf-III versus Draf-IIa required more postoperative clinic visits (4.9 ± 1.7 versus 3.3 ± 0.8; p < 0.05), debridements (4.2 ± 2.0 versus 2.3 ± 0.8; p < 0.05), and antibiotic therapy days (24.4 ± 11.8 versus 15.6 ± 6.3; p < 0.05). The mean (SD) SNOT-22 scores improved for both groups (-12.7 ± 34.5 versus -9.5 ± 20.4; p = 0.74) over the follow-up period, and subscore (domain) analysis demonstrated worsening extranasal symptoms (2.5 ± 3.0 versus -1.5 ± 4.7; p < 0.05) at the first postoperative visit, and less improvement in ear/facial symptoms at the second (-0.5 ± 2.6 versus -3.9 ± 4.7; p = 0.03) and third postoperative visits (-1.1 ± 1.6 versus 3.5 ± 3.3; p = 0.01). CONCLUSION Draf-III is associated with more postoperative clinic visits, debridements, and antibiotic therapy days. The patients who underwent Draf-III demonstrated worsening of extranasal symptoms at the first postoperative visit and less improvement in the ear/facial score at the second and third visits. Informed consent and counseling patients who may require Draf-III should include a detailed discussion of the burden of postoperative care and recovery.

Frontal sinus revision rate after nasal polyposis surgery including frontal recess clearance and middle turbinectomy: A long-term analysis. Auris Nasus Larynx 2017; 45:740-746. [PMID: 29150349 DOI: 10.1016/j.anl.2017.11.005] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2017] [Revised: 10/21/2017] [Accepted: 11/06/2017] [Indexed: 11/26/2022]
Abstract
OBJECTIVE To determine the frontal sinus revision rate after nasal polyposis (NP) surgery including frontal recess clearance (FRC) and middle turbinectomy (MT), to search for predictive factors and to analyse surgical management. METHODS Longitudinal analysis of 153 patients who consecutively underwent bilateral sphenoethmoidectomy with FRC and MT for NP with a minimum follow-up of 7 years. Decision of revision surgery was made in case of medically refractory chronic frontal sinusitis or frontal mucocele. Univariate and multivariate analysis incorporating clinical and radiological variables were performed. RESULTS The frontal sinus revision rate was 6.5% (10/153). The mean time between the initial procedure and revision surgery was 3 years, 10 months. Osteitis around the frontal sinus outflow tract (FSOT) was associated with a higher risk of frontal sinus revision surgery (p=0.01). Asthma and aspirin intolerance did not increase the risk, as well as frontal sinus ostium diameter or residual frontoethmoid cells. Among revised patients, 60% required multiple procedures and 70% required frontal sinus ostium enlargement. CONCLUSIONS Our long-term study reports that NP surgery including FRC and MT is associated with a low frontal sinus revision rate (6.5%). Patients developing osteitis around the FSOT have a higher risk of frontal sinus revision surgery. As mucosal damage can lead to osteitis, FSOT mucosa should be preserved during initial NP surgery. However, as multiple procedures are common among NP patients requiring frontal sinus revision, frontal sinus ostium enlargement should be considered during first revision in the hope of reducing the need of further revisions.

Abstract
Importance Suboptimal outcomes of endoscopic sinus surgery (ESS) are often associated with restenosis and inflammation of frontal sinus ostia. Steroid-releasing sinus implants have been shown to maintain sinus patency by minimizing inflammation and scar tissue formation. An hourglass-shaped, bioabsorbable, steroid-releasing implant was developed to provide mechanical support and optimize drug delivery to paranasal sinus ostia. Objective To assess the safety and efficacy of the hourglass-shaped, bioabsorbable, steroid-releasing sinus implant in improving postoperative outcomes when placed in the frontal sinus ostia (FSO) following ESS in patients with chronic rhinosinusitis (CRS). Design, Setting, and Participants In a prospective, multicenter, randomized clinical trial using an intrapatient control design (ESS followed by implant placement within 1 FSO vs ESS alone on the contralateral side) 80 adult patients, with a mean (SD) age of 49.5 (13.4) years and consisting of 53 (66%) men and 27 (34%) women, were enrolled and underwent bilateral frontal sinusotomies with 1 frontal sinus randomized to receive a steroid-releasing implant. The study was carried out in 12 US centers between July 2015 and March 2016. Interventions A bioabsorbable steroid-releasing implant with hourglass shape containing 370 µg of mometasone furoate. All patients received standardized postoperative care. Main Outcomes and Measures The need for postoperative interventions, medical and surgical, in the FSO at day 30, as determined based on review of video endoscopic findings by an independent blinded surgeon. Also, endoscopic grading by the independent reviewer and clinical investigators at day 30 and day 90 and computed tomographic scan at day 90. Results The mean (SD) age of patients was 49.5 (13.4) years, 53 (66%) were men. Implants were successfully placed in all 80 randomized treatment sinuses. At day 30, steroid-releasing implants significantly reduced the need for postoperative interventions to 11.5% compared with 32.8% by surgery alone (mean difference, -21.3%; 95% CI, -35.1% to -7.6%), as assessed by the independent reviewer. Real-time endoscopic assessment by clinical investigators at day 30 demonstrated significant reduction in need for postoperative intervention (mean difference, -17.3%; 95% CI, -27.9% to -6.7%), significant reduction in inflammation score (mean difference, -12.3 mm; 95% CI, -18.3 to -6.4 mm), and significant reduction in rate of frontal restenosis or occlusion (mean difference, -22.7%; 95% CI, -33.5% to -11.9%) on treated compared with control sides. The results favoring the treatment sides were sustained through day 90: reduced need for postoperative interventions (mean difference, -11.7%; 95% CI, -21.0% to -2.4%) and reduction in restenosis and/or occlusion of the frontal ostium (mean difference, -17.4%; 95% CI, -28.6% to -6.1%). No implant-related adverse events were observed. Conclusions and Relevance The hourglass-shaped steroid-releasing sinus implant was safe and more effective in maintaining FSO patency and improving surgical outcomes compared with surgery alone in the setting where no other immediate postoperative corticosteroids were administered. Trial Registration ClinicalTrials.gov identifier: NCT02266810.

Abstract
The aim of this study is to describe the morphology of frontal recess area with its anatomical variations and to reveal if frontal recess morphology and the anatomical variations related to that region have effects on the pneumatization of the frontal sinuses. The frontal sinus and recess morphometry of 136 sides of 68 dry skulls were evaluated on multislice high-resolution computed tomography. The relationships between frontal sinus and frontal recess measurements were analyzed by correlation and linear regression analysis. The variables between the groups of anatomical variations were analyzed by Mann-Whitney U test and χ test or Fisher exact test. A positive relationship between the sagittal length of spina nasalis interna and morphometric measurements of frontal sinus was revealed (P <0.05). Agger nasi cells were present in 64.2% of sides, supraorbital ethmoid cells (SOECs) in 19.6%, type 3 frontal cells (FCs) in 18.9%, suprabullar cells in 24.3%, and frontal bulla was noted in 5.4%. Intersinus septal cells were observed in 16.2% of the skulls. There were statistically different increases in the measurements of frontal sinus morphometry in the presences of SOECs and type 3 FCs (P <0.05). The diameter of frontal sinus ostium was decreased in the presences of AN, SOEC, type 3 FC, and supraorbital ethmoid cell statistically (P = 0.049, P = 0.029, P = 0.043, P <0.001 respectively). In conclusion, frontal sinus pneumatization was affected by the spina nasalis interna and the presence of anatomical variations related to frontal recess or ostium region instead of the morphology of that area.

Abstract
Endoscopic sinus surgery is an effective intervention at improving quality of life for patients with medically refractory chronic rhinosinusitis. The evidence supporting frontal sinusotomy is limited to single institution case series. However, the data for Draf IIa frontal sinusotomy do demonstrate that most patients experience lasting frontal sinus patency on postoperative endoscopic examination and improvements in quality of life. Salvage endoscopic frontal sinus surgery via a Draf III shows high rates of neo-ostium patency and subjective improvements in symptoms at a 2-year time point in case series.

Abstract
INTRODUCTION Propel and Propel Mini sinus implants are mometasone furoate-coated bioabsorbable stents used as an adjunct in the management of chronic rhinosinusitis after endoscopic sinus surgery. The original sinus implant was deployed in the ethmoid sinuses to provide medialization of the middle turbinate, decrease scarring and mucosal adhesions, limit polyp regrowth, and reduce mucosal inflammation. A structurally smaller version of the Propel, the Propel Mini, was developed and now has been approved for endoscopic placement in the frontal sinuses. Areas covered: This evaluation will focus on the technical details of the Propel mini, previous studies documenting Propel's success in the ethmoid sinuses, and the safety and efficacy of the Propel mini implants in frontal sinus surgery. Expert opinion: Devices such as the Propel and Propel Mini stents are the beginning of a trend towards medication-coated bioabsorbable implants that can be used for sinonasal disease to minimize complications or possible side effects of surgical treatment by an increase of topical drug delivery locally.

Abstract
PURPOSE Ostial restenosis is a common cause of failures in paranasal sinus surgery. The aim of the current study was to investigate the use of low-dose-rate brachytherapy to prevent neo-ostial restenosis in an animal model. METHODS AND MATERIALS In 14 rabbits, maxillary neo-ostia were created and measured. One side each was stented with a regular silicone stent, the other side was either not stented (n = 7) or stented with a phosphorous-32 implanted stent depositing a low-dose radiation of 15 Gy (n = 7) within 1 week, after which all stents were removed. After a period of additional 12 weeks of recovery, the animals were sacrificed, the neo-ostia were again measured, and the areas and histopathologic changes compared in between the groups. RESULTS After 15-Gy stenting, the mean ostial areas were even slightly enlarged by 5.1% compared to the area at stent removal, whereas a significant reduction in area, indicating a process of restenosis, by 56.1% or 54.0% was seen in the control groups with no stent and normal stent, respectively. Furthermore, no indication for adverse histopathologic radiation effects was seen in the 15-Gy group. CONCLUSIONS Low-dose-rate brachytherapy with phosphorous-32 doped silicone stents showed promising results in the prevention of neo-ostium restenosis in this proof-of-concept study, indicating that further preclinical and clinical testing may be warranted.

Abstract
OBJECTIVES/HYPOTHESIS To assess safety and efficacy of a steroid-releasing implant in improving surgical outcomes when placed in the frontal sinus opening (FSO) following endoscopic sinus surgery (ESS) in patients with chronic rhinosinusitis (CRS). STUDY DESIGN Prospective, multicenter, randomized, blinded trial using an intrapatient control design. METHODS Eighty adult (≥ 18 years) CRS patients who underwent successful bilateral frontal sinusotomy were randomized to receive a steroid-releasing implant in one FSO, whereas the contralateral control side received no implant. All patients received standard postoperative care. Endoscopic evaluations recorded at 30-days postendoscopic sinus surgery (ESS) were graded real time by clinical investigators and by an independent, blinded sinus surgeon to assess the need for postoperative interventions in the FSO. RESULTS Implants were successfully placed in all 80 frontal sinuses, resulting in 100% implant delivery success. At 30-days post-ESS, steroid-releasing implants provided a statistically significant (P = 0.0070) reduction in the need for postoperative interventions compared to surgery alone by an independent reviewer, representing 38% relative reduction. Clinical investigators reported statistically significant reduction in this measure at 30 days (P < 0.0001) and 90 days (P = 0.0129). Clinical investigators also reported a 55.6% reduction in the need for oral steroid interventions (P = 0.0015), 75% reduction in the need for surgical interventions (P = 0.0225), 16.7% reduction in inflammation score, 54.3% reduction in restenosis rate (P = 0.0002), and 32.2% greater diameter of FSO (P < 0.0001) on treated sides compared to control at 30 days. No implant-related adverse events were reported. CONCLUSION This study demonstrates the efficacy of steroid-releasing implants in improving outcomes of frontal sinus surgery. LEVEL OF EVIDENCE 1b.

Abstract
BACKGROUND Endoscopic modified Lothrop procedure (EMLP) is used to treat patients who fail conventional sinus surgery. The failure rate of a primary EMLP is reported to be between 5% and 32%. The failure rate of revision EMLP has not been reported. We present our institutions data regarding the outcome of patients requiring revision EMLP. METHODS Data was collected prospectively. Patients undergoing primary EMLP between January 2001 and December 2013 with a minimum follow-up of 6 months were included. Information related to demographics, asthma status, aspirin sensitivity, 22-item Sino-Nasal Outcome Test (SNOT-22) score, Lund-Mackay scores, intraoperative findings, and endoscopic ostium assessment were collected. RESULTS There were 213 primary EMLPs completed with average follow-up of 36 months. The failure rate of primary EMLP was 8.9% (19/213), whereas the failure rate of revision EMLP was 21% (4/19). Risk factors for failure of primary EMLP included the presence of intraoperative pus, more than 5 previous sinus operations and aspirin-exacerbated respiratory disease (AERD). Revision of EMLP was undertaken primarily due to recurrence of nasal polyps or ostium stenosis. Those patients who underwent revision EMLP experienced symptomatic improvement and no major complications following the procedure. CONCLUSION The failure rate of revision EMLP is 21% in our series. The majority of revisions were for nasal polyp recurrence. Revision EMLP is a safe and well-tolerated procedure in the small group of patients that require further surgery. Patients with intraoperative pus present at their initial EMLP, more than 5 previous sinus operations, or AERD are at increased risk of failure.

Abstract
Endonasal endoscopic sinus surgery is the standard procedure for surgery of most paranasal sinus diseases. Appropriate frame conditions provided, the respective procedures are safe and successful. These prerequisites encompass appropriate technical equipment, anatomical oriented surgical technique, proper patient selection, and individually adapted extent of surgery. The range of endonasal sinus operations has dramatically increased during the last 20 years and reaches from partial uncinectomy to pansinus surgery with extended surgery of the frontal (Draf type III), maxillary (grade 3-4, medial maxillectomy, prelacrimal approach) and sphenoid sinus. In addition there are operations outside and beyond the paranasal sinuses. The development of surgical technique is still constantly evolving. This article gives a comprehensive review on the most recent state of the art in endoscopic sinus surgery according to the literature with the following aspects: principles and fundamentals, surgical techniques, indications, outcome, postoperative care, nasal packing and stents, technical equipment.

Abstract
Despite innovative surgical techniques and use of current frontal sinus stents from different materials, the problem of treatment failure with consecutive reoperation remains present. The aim of our study is to investigate biocompatibility, degradation kinetics, and functionality of a newly developed fluoride-coated magnesium-based nasal stent. A minipig anatomy of frontal sinus adapted design and an external surgical approach were developed and established. The functionality of the stents was evaluated endoscopically. The stent-tissue blocks were analysed after 90 and 180 days using microcomputed tomography (µ-CT), histology, scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDS). Functional evaluation revealed an unobstructed stent lumen in all cases. Histological analysis showed moderate mucosal hyperplasia with a mild, nonspecific inflammatory response, and nonosteoconductive effect. Rejection reactions or necrosis did not occur. The volumetric analysis of the stents showed 51% volume loss after 180 days. The EDS analysis did not detect any neodymium (Nd) in the mucosa or bone. The Mg-2 wt % Nd stents are a promising option when treating the narrow passages following paranasal sinus surgery. In particular, its good biocompatibility and good functionality facilitate the re-epithelization of these constricted passages. © 2015 Wiley Periodicals, Inc.

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
Up to now, different surgical techniques and stent systems have already been developed and tested for the continuous and adequate ventilation of the frontal sinuses. However, the results achieved still remain poor. Magnesium-based implants have been successfully used in numerous clinical applications. Offering excellent biocompatibility and biodegradability it may be the ideal material for the development of novel implants of the nasal sinus. Here, we present for the first time results on the behaviour of magnesium alloy in a unique environment, i.e. in contact to the nasal mucosa, air and nasal secretion. In a prospective longitudinal study, magnesium fluoride-coated MgNd2 specimens were implanted in the frontal sinuses of 12 minipigs for the investigation of biocompatibility and of the interface between the implant and the mucosa. Endoscopic examinations, histopathological evaluation and EDX measurements were performed regularly up to 180days. Endoscopic evaluation showed focal mucosal reaction, however, without affecting the patency of the sinus. In addition, no signs of bacterial infections were observed. The EDX analyses showed a marginal but steady increase in the Mg concentration in the mucosa over 180days. Histological analysis revealed a locally confined moderate mucosal hyperplasia and unspecific inflammatory reaction. Furthermore, we did not find any osteoinductive effects of the magnesium alloy. The results indicate the excellent biocompatibility of the MgNd2 alloy in contact with nasal mucosa and provide a novel material compound and solid proof-of-principle for the development of magnesium-based nasal stents.

Abstract
BACKGROUND Previous studies of endoscopic frontal sinus surgery have been primarily retrospective and focused on symptom relief only. OBJECTIVES To prospectively assess the impact of endoscopic frontal sinus surgery on frontal sinus ostium patency and disease-specific quality of life as measured by the Rhinosinusitis Disability Index (RSDI). STUDY DESIGN A 60-patient cohort with chronic frontal sinusitis (100 diseased frontal sinuses) was prospectively evaluated using the RSDI, computed tomography (CT) imaging, and endoscopic examination. Image-guided endoscopic frontal sinusotomy (Draf 2a) was performed in each case. Patients were assessed with RSDI and endoscopic assessment at least 6 months postoperatively. RESULTS At a mean follow-up of 10 months, endoscopic assessment revealed patent frontal recesses in 90 of 100 frontal sinuses (90%), with significant improvement in the total RSDI score (41.98 ± 26.48 preoperatively to 17.15 ± 15.66 postoperatively) as well as each of its physical, emotional, and functional subscales from 16.3 ± 9.03, 12.23 ± 10.55, 13.45 ± 9.59 preoperatively to 5.95 ± 5.71, 5.55 ± 5.66, 5.65 ± 5.72 postoperatively, respectively. Similar improvement was seen in patients with asthma, polyps, and those undergoing revision sinus surgeries. CONCLUSIONS With frontal recess mucosal preservation and meticulous postoperative endoscopic surveillance, endoscopic frontal sinusotomy results in high rates of frontal sinus ostium patency with significant improvement in quality of life.

Abstract
Achieving long-term, successful outcomes with endoscopic sinus surgery (ESS) can be challenging in patients with recalcitrant chronic rhinosinusitis (CRS). Local complications, including scar formation and ostial stenosis, can lead to recurrent blockage and subsequent relapse. The frontal sinus is particularly vulnerable to surgical failure given its narrow outflow and inaccessibility to topical therapies. The advent of steroid-eluting sinus implants has enhanced ESS outcomes, with significant reductions in synechiae, inflammation, and secondary postoperative interventions when placed in the ethmoid cavity. However, use of this technology in the frontal sinus has yet to be described. The purpose of this report is to present two cases, in which in-office frontal placement of a mometasone furoate (MF)-eluting implant facilitated maintenance of ostial patency after revision ESS. The clinical presentation, in-office intervention, and treatment outcomes were examined. Two patients (male, 63 and 68 years of age) with a history of multiple ESS presented with recurrent unilateral frontal headache refractory to medical therapy. Nasal endoscopy/imaging revealed frontal sinus outflow obstruction. Both declined revision ESS under general anesthesia and underwent endoscopic frontal sinustomy/ostial dilation in the clinic. A MF-eluting implant was placed in the frontal sinus at the end of the procedure, with preservation of ostial patency upon last follow-up at 3 and 11 months, respectively. In-office placement of a MF-eluting implant successfully maintained frontal ostial patency in patients with a history of multiple ESS. Additional randomized trials are necessary to determine statistical significance, cost-effectiveness analysis, and long-term efficacy of frontal sinus implantation.

Abstract
BACKGROUND The frontal sinus is the most challenging area to address in endoscopic sinus surgery (ESS). Incomplete surgery or iatrogenic injury in the narrow space of the frontal recess with synechia formation can lead to recurrence or persistence of disease. The goal of this study was to identify causes of failure of endoscopic frontal sinus surgery and to determine complication rates. METHODS A cross-sectional retrospective study was conducted. Charts and preoperative sinus computed tomography (CT) scans of patients who underwent revision frontal ESS for chronic frontal rhinosinusitis, between 2006 and 2012 were reviewed. RESULTS Of 829 patients who underwent ESS during the study period, 740 had the frontal recess dissected and frontal sinus opened. Of these, 66 patients had revision surgery of the frontal sinus, with a total of 109 frontal sinuses. The mean ± standard deviation (SD) age was 52 ± 12.9 years. Forty patients were male (59.1%). The most common findings were the following: edematous or hypertrophic mucosa (92.7%); retained agger nasi cell (73.4%); neo-osteogenesis within the frontal recess (45.9%); lateral scarring of the middle turbinate (47.7%); residual anterior ethmoid air cell (32.1.%); and residual frontal cells (24.8%). CONCLUSION With the exception of mucosal disease and neo-osteogenesis, all identified causes of failure of frontal sinus surgery are a result of surgical technique. Careful preoperative planning and meticulous and complete surgical execution are therefore critical for a successful surgical outcome in primary frontal sinus surgery.

Abstract
OBJECTIVES/HYPOTHESIS To detail the long-term outcomes of the endoscopic modified Lothrop procedure (EMLP) (also know as Draf III/frontal drillout) and identify key risk factors for failure. STUDY DESIGN Retrospective cohort study and chart review. METHODS Endoscopic assessment of frontal ostium patency and patient-reported symptoms were prospectively collected on patients who underwent EMLP between January 2001 and December 2011 for chronic rhinosinusitis (CRS). Risk factors for failing EMLP were identified. RESULTS There were 229 patients who met the inclusion and exclusion criteria and underwent an EMLP. The average number of standard endoscopic sinus surgery procedures prior to an EMLP was 3.8 (95% confidence interval [CI]: 3.4-4.2, standard deviation [SD]: 3.3).The average length of follow-up was 45.0 months (95% CI: 41.2-48.9 months, SD: 22.3 months). The EMLP was successful in 95% (217/229), with no further surgery being required. Postsurgical recurrence of disease with persistence of symptoms requiring revision EMLP occurred in 12 patients. No complications were identified. Allergic fungal sinusitis and recurrent Staphylococcus aureus infections were identified as potential risk factors for failure. CONCLUSIONS This is the single largest study of EMLP in the literature with a long follow-up period. It illustrates the benefit of the EMLP for patients with CRS recalcitrant to medical and standard endoscopic sinus surgery.

Abstract
Treatment of frontal sinus disease represents one of the most challenging aspects of endoscopic sinus surgery. Frontal sinus mucocele drainage may be an exception to the rule because in many instances, the expansion of the mucocele widens the frontal sinus recess and renders surgical drainage technically undemanding. Recently, there has been an increased interest in in-office procedures in otolaryngology because of patient satisfaction and substantial savings of time and cost for both patients and physicians. Similarly, the past few years have witnessed an increased use of balloon dilation devices in sinus surgery. Previously, we have described the in-office use of this device in treating patients who failed prior conventional frontal sinusotomy in the operating room. In this report, we describe our step-by-step in-office experience using this tool for drainage of a large frontal sinus mucocele.

A blinded randomized controlled trial evaluating the efficacy of chitosan gel on ostial stenosis following endoscopic sinus surgery. Int Forum Allergy Rhinol 2013; 3:573-80.

Abstract
BACKGROUND Stenosis of sinus ostia following endoscopic sinus surgery (ESS) is the most common reason for revision surgery. Chitosan-dextran (CD) gel has been shown to be an effective hemostatic agent; however, its effects on ostial stenosis are unknown. This study aims to quantify the effect of CD gel on circumferential scarring following ESS. METHODS A prospective, blinded, randomized, controlled trial was conducted in 26 patients undergoing ESS. Measurements of neo-ostia were taken using a standard-sized measuring probe. CD gel was applied unilaterally, while contralateral sides received no gel. Ostial diameters were measured by a blinded observer at 2, 8, and 12 weeks postoperation. Sinus ostial areas calculated as a proportion of the original were compared for each ostium at each time point. RESULTS Intraoperative ostial areas were comparable for CD gel and control sides (38 mm(2) vs 39 mm(2) , 131 mm(2) vs 120 mm(2) , and 203 mm(2) vs 193 mm(2) , in frontal, sphenoid, and maxillary ostia, respectively; p > 0.05). CD gel significantly improved sinus ostial patency. The largest difference was seen when ostial areas at 12 weeks were compared with their corresponding baseline areas (66% vs 31% frontal, p < 0.001; 85% vs 47% sphenoid, p < 0.001; and 74% vs 54% maxillary ostia, p = 0.002). The difference between raw ostial areas reached statistical significance in sphenoid (p < 0.001) and maxillary (p = 0.01), but not in frontal ostia (p > 0.05) at 12 weeks. CONCLUSION CD gel produced significantly less stenosis of all neo-ostia following ESS and may reduce the necessity for revision surgery in patients with chronic rhinosinusitis.

Abstract
BACKGROUND The purpose of this level 4, retrospective cohort study was to detail the outcomes of primary, revision, and endoscopic modified Lothrop procedure (EMLP) (Draf III) frontal sinus surgery and evaluate whether risk factors would help determine which patients would benefit from which procedures. METHODS The study used a retrospective chart review. Endoscopic assessment of frontal ostium patency and patient reported symptoms were prospectively collected on patients who underwent frontal sinusotomy between January 2003 and December 2009. High-risk cohorts were studied to assess their response to standard endoscopic sinus surgery (ESS) compared with EMLP. RESULTS A total of 339 patients who met the inclusion and exclusion criteria underwent either primary or revision endoscopic frontal sinus surgery. The average ± standard deviation (SD) length of follow-up was 20.8 ± 18.7 (95% confidence interval [CI], 18.0-22.9) months. Postsurgical recurrence of disease with persistence of symptoms requiring an EMLP occurred in 9 patients in the primary group and 38 in the revision group. The highest risk groups for failure of standard frontal sinusotomy were patients with nasal polyps, asthma, Lund-Mackay score >16, and frontal ostium size <4 mm (relative risk = 9.9, p < 0.0001). CONCLUSION Patients with underlying asthma and polyposis as well as narrow frontal ostia and extensive radiological disease have a high failure rate from standard endoscopic frontal sinusotomy. In this patient group consideration should be given to offering the patient a primary EMLP procedure, which has excellent success rates with low risks and low morbidity.

Abstract
BACKGROUND Nasal polyposis represents the end point of multiple inflammatory pathways and controversy continues as to the exact roles of medical and surgical approaches in the management of nasal polyposis. METHODS A combination of both is often required to manage polyps adequately with surgery and intranasal steroids remaining the mainstay of therapy. RESULTS Fortunately, new technological advances are making surgery safer and more efficient. In the postoperative period, debridement is effective in reducing the formation of adhesions, and topical medications may play a beneficial role in preventing polyp reformation. CONCLUSION Additional investigations into the optimal perioperative medical management is needed to ensure optimal surgical outcomes.

Abstract
BACKGROUND The objectives of this study were to evaluate the long-term frontal ostium patency rate and symptom improvement in patients undergoing primary endoscopic frontal sinusotomy (Draf 2A) and to assess the impact of patient factors, disease factors, and frontal ostium size on surgical outcomes. METHODS Retrospective chart review was used. Endoscopic assessment of frontal ostium patency and patient-reported symptoms were prospectively collected on patients who underwent primary frontal sinusotomy between January 2003 and December 2009. RESULTS A total of 109 patients underwent primary endoscopic surgery on 210 frontal sinuses over the study period. The overall patency rate was 92%. Complete resolution of symptoms was noted in 85 patients (78%). Stenosis of the frontal sinus ostium correlated significantly with persistence of symptoms, infection, or polyp recurrence (p = 0.0066), and frontal ostium size (p < 0.03). No significant correlation could be found between the presence of eosinophilic mucin, asthma, polyposis, and smoking on patency or resolution of symptoms. CONCLUSION To our knowledge, this is the largest study of primary endoscopic frontal sinus surgery in the literature. The technical and subjective measures of success are high. Frontal ostium size correlates with risk of stenosis of the frontal sinus. Patients with a stenosed frontal ostium and residual frontal sinus disease are more likely to be symptomatic or have endoscopic evidence of polyp recurrence or endoscopic evidence of persistent infection. Asthma, eosinophilic mucin chronic rhinosinusitis (EMCRS), allergy, and smoking do not appear to affect outcomes.

Abstract
The Messerklinger technique is an endoscopic approach to sinus surgery designed to be minimally invasive and preserve mucosa and hence physiological function. More recently there have been advocates for more radical endoscopic approaches to the frontal sinus such as the Modified Lothrop. This review discusses different approaches to frontal sinus surgery including any advantages and disadvantages to each approach. After examining the evidence from the literature, meticulously performed endoscopic frontal sinusotomy with or without computer guidance appears to be the most effective minimally invasive procedure for treating chronic frontal sinusitis secondary to outflow tract obstruction. Properly performed, it is almost always effective in dealing with even the most diseased frontal sinus. It offers clear advantages in reducing complications and recurrence rates in frontal sinus disease, even for revision cases.

Abstract
OBJECTIVE The frontal sinus outflow tract consists anatomically of narrow channels prone to stenosis. Following both endonasal and external approach surgery, up to 30 per cent of patients suffer post-operative re-stenosis of the frontal sinus outflow tract, with recurrent frontal sinus disease. This paper proposes the surgical placement of a long-term frontal sinus stent to maintain fronto-nasal patency, as an alternative to more aggressive surgical procedures such as frontal sinus obliteration and modified Lothrop procedures. DESIGN We present a series of three patients with frontal sinus disease and significant co-morbidity, the latter making extensive surgery a significant health risk. We also review the relevant literature and discuss the use of long-term frontal sinus stenting. RESULTS These three cases were successfully treated with long-term frontal sinus stenting. Stents remained in situ for a period ranging from 48 to over 60 months. CONCLUSION Due to the relatively high failure rates for both endonasal and external frontal sinus surgery, with a high post-operative incidence of frontal sinus outflow tract re-stenosis, long-term stenting is a useful option in carefully selected patients.

Abstract
Synechiae and ostial stenosis are common and troublesome complications following endoscopic sinus surgery. Many investigators have advocated the use of stents to minimize the risk of postoperative stenosis while others have found their use to be of no benefit. This article reviews the advantages and disadvantages of various stents used in sinus surgery, and discusses such innovations as drug-releasing stents.

Abstract
Endonasal frontal sinus surgery aims to create adequate access to the frontal sinus, remove specific pathologic processes, and establish a permanent and sufficient drainage and ventilation. We present a concept of frontal sinus surgery that depends on the individual anatomy of the frontal and ethmoid sinuses and includes a stepwise intensity of the surgical procedure. Endonasal frontal sinus drainage according to Draf ranges from uncinectomy to the maximal procedure, type III drainage; these procedures are outlined in detail. A comprehensive overview of technical aspects to optimize the operative technique and postoperative results is given. Surgical details include the application of nasal packing, mitomycin C, mucosal transplants, silicone foils or stents, and the new technology of balloon sinuplasty. Specific instrumentation and endoscopic equipment are recommended. Part 1 deals with types I and II frontal sinus drainage. Part 2 explains type III drainage, technical details, and special aspects of postoperative care.
