Background Methods Results Conclusions Functional endoscopic sinus surgery (FESS) is one of the most commonly performed otolaryngologic procedures and is associated with significant cost variability.We performed a retrospective analysis of all inflammatory sinus surgeries at a single tertiary care medical center from July 2021 to July 2023. The electronic medical record was reviewed for patient factors and cost variables for each procedure, and multivariable analysis was performed.A total of 221 patients were included in analysis with a mean age of 48.2 years. There was a 44.8% incidence (n = 99) of nasal polyps and 31.2% (n = 69) of cases were revision surgeries. The average total cost for the surgical encounter was $8960.31 (standard deviation $1967.97). Operating room time represented $4912.46 (54.8% of all costs), while average operating room supply costs were $1296.06 (14.5%) and recovery room costs were $919.48 (10.3%). Total costs were significantly associated with length of surgery ($7.83/min, p = 0.04), in addition to presence of nasal polyps ($531.96, p = 0.04). There was no significant association between total costs and the remaining clinical and demographic factors.Costs associated with ambulatory FESS for inflammatory sinus disease vary across patients and this cost variability is predominantly driven by time efficiency within the operating room, as well as supply utilization and nasal polyposis to a lesser degree. As a result, operating room efficiency represents a primary target for cost‐related interventions. Additionally, our data provide a framework for surgeons and hospitals to make evidence‐based decisions on intraoperative equipment in a tradeoff between efficiency and supply costs. Our findings indicate that an approach focused on streamlining efficiency across the entire ambulatory surgery encounter will have the greatest impact on reducing healthcare expenses for both the patient and the health system.

Some cases of chronic rhinosinusitis (CRS) require surgical treatment and postoperative nasal packing, but bleeding and adhesion are common complications after nasal surgery. Biodegradable drug-loaded implants hold great therapeutic options for the treatment of CRS, but little data are available regarding the safety and efficacy of a novel drug-loaded haemostatic sponge (DLHS) in the sinus. The aim of this study was to investigate the safety and efficacy of DLHS in the sinus. We conducted a prospective, randomized, controlled, double-blind clinical trial. In this clinical trial, 49 patients were enrolled and randomly divided into 2 groups: group A (n = 25) had the DLHS containing 1 mg budesonide and 0.67 mg sodium hyaluronate placed into the sinus, and group B (n = 24) had the Nasopore placed after ESS. Endoscopic follow-up was performed for 12 weeks, and the findings were classified using the discharge, inflammation, polyps/oedema (DIP) endoscopic appearance scores. All patients completed questionnaires to evaluate their sinonasal symptoms by using the sinonasal outcome test-22 (SNOT-22) Chinese version and visual analogue scale (VAS). Serum cortisol concentration in group A was measured prior to surgery and at days 1, 3, 7, and 14 after nasal surgery. Comparing group A and group B, at 2 weeks, no significant differences were observed in either objective or subjective parameters. The mean value of VAS for rhinorrhoea and DIP for oedema and the mean value of nasal adhesion were significantly lower in Group A than in Group B at 6 and 12 weeks, but a significant difference did not occur in SNOT-22 and VAS for dysosmia between the two groups at 6 and 12 weeks. The mean serum cortisol concentrations in group A at the follow-up were within normal limits without remarkable fluctuations. This study demonstrates the safety and efficacy of a novel biodegradable DLHS with the possibility of being used in CRS patients, and this sponge may reduce inflammation and minimize adhesions via controlled local drug delivery without measurable systemic exposure.

Background: The posterior ethmoid sinuses have a complex anatomy and a highly variable normal structure. The posterior ethmoid Onodi cell needs careful assessment because of its proximity to the optic nerve and the internal carotid artery canal. Recognising the distinctions is essential for optimal pre-op preparation. Sphenoid sinus surgery can now be performed without worrying about compromising vital structures like the internal carotid artery or optic nerve. Preoperative radiological assessment is a quick and easy way to check for ethmoid cell pneumatisation differences. Aim and objectives: To determine the pneumatisation patterns of Onodi cells among the North-East Indian population using 16-slice multidetector computed tomography (MDCT). Results: Nine-hundred MDCT paranasal sinuses were analysed over a period of 0–2 years, out of which 220 cases showed the presence of Onodi cell. Type I were 89 cases (40.45%, CI 32.00–48.90), Type II were 128 cases (58.18%, CI 49.72–66.63), and 3 cases with Type III cell (1.36%, CI 0.18–2.54). Conclusion: The most prevalent pneumatisation pattern is Type II. The pneumatisation patterns of Onodi cells can be best detected and evaluated by multiplanar MDCT imaging. Sinus surgeons need a firm grasp of pneumatisation patterns to avoid damaging the optic nerve and internal carotid artery canal during operations. [ABSTRACT FROM AUTHOR]

Background: Headache and facial pain are common symptoms of chronic rhinosinusitis (CRS). However, given the numerous etiologies that can cause these symptoms, the impact of sinus surgery is not well characterized. Methods: A systematic review was performed by searching the literature from inception through June 6, 2023. English‐language articles reporting outcomes for facial pain/pressure or headache following endoscopic sinus surgery were selected for inclusion. Meta‐analyses were performed using random and fixed effect models on continuous measures (mean), mean difference (Δ), and proportions (%). Results: A total of 26 articles reporting on 2839 patients were selected for inclusion. The mean patient age was 44.0 ± 3.9 (range 16.0–84.0), with an average symptom duration of 5.3 ± 2.8 years. Among these patients, 56.5% (95% confidence interval [CI]: 52.3–60.6) were male and 77.0% (95% CI: 56.6–92.3) had nasal polyposis (NP). Patients with and without NP reported substantial reductions in both 22‐item sino‐nasal outcome test facial pain/pressure (with NP: −1.4 [95% CI: −1.6 to −1.2; relative reduction 59.1%]; without NP: −1.5 [95% CI: −1.9 to −1.1; relative reduction 60.9%]) and visual analogue scale (VAS) headache (with NP: −2.5 [95% CI: −2.8 to −2.1; relative reduction 67.2%]; without NP: −2.8 [95% CI: −4.7 to −1.0; relative reduction 42.7%]). Symptom reductions were greater in the without NP versus with NP group; VAS facial pain/pressure: Δ0.4 (95% CI: 0.2–0.6; p = 0.0006) and VAS headache: Δ0.4 (95% CI: 0.1–0.7; p = 0.02). Conclusions: Our findings suggest that CRS patients, regardless of polyp status, benefit from significant reductions in facial pain/pressure and headache following surgical therapy.

Nasal surgeries (e.g.: rhinoplasties, septoplasties) and sinus surgeries (e.g.: Functional Endoscopic Sinus Surgeries) are common procedures in Otorhinolaryngology. Tranexamic acid (TXA), an antifibrinolytic drug, has been increasingly utilized to reduce hemorrhage recently. While close in proximity anatomically, the bleeding nature of sinus and nasal surgeries may differ. We present the first meta-analysis that has reviewed both nasal and sinus surgery collectively and compares the two. Pubmed, Embase, Cochrane Library and WoS were searched until April 2023. Outcomes of interest include Boezart Scoring, clotting time, postoperative complications and surgical field quality. 27 Studies were assessed, of which 25 studies were evaluated quantitatively. Of the 27 studies, 15 studies involved Sinus surgery while 12 involved Nasal surgery. The use of tranexamic acid was notably beneficial in the evaluation of blood loss, reduction of operating time, surgical field quality and surgeon satisfaction. TXA has proven to be efficacious in both nasal and sinus surgeries to varying degrees. TXA has more effects in sinus surgeries compared to nasal surgeries in objective markers such as reducing blood loss and operating time, but the converse occurs for subjective markers such as surgeon satisfaction scores.

Introduction: We describe the first case of ALHE in the orbit with extension to the maxillary sinus and the importance of a multidisciplinary approach to achieve removal of the lesion. Case study: A 72-year-old man presented with epiphora of the left eye and several episodes of recurrent acute dacryocystitis. Magnetic resonance imaging revealed a solid homogeneous mass located in the inferomedial region of the left orbit. In addition, it was associated with destruction of the adjacent ethmoidal wall and upper wall of the left maxillary sinus. Incisional biopsy of the orbital mass was compatible with ALHE. Results: It was decided to perform surgery using an orbital floor approach, left medial wall via subconjunctival and caruncular approach together with an endoscopic nasal approach (ESS), achieving complete removal of the orbital mass and cleaning of the maxillary sinus. After one year of treatment, no tumor recurrence was evident through endoscopy and imaging tests and the patient is asymptomatic. Conclusions: ALHE is a very rare benign vascular tumor that presents subcutaneous nodules in the head and neck region. We do not know of any case of ALHE in the paranasal sinuses described in the literature, either in isolation or together with orbital or cutaneous ALHE. In conclusion, ALHE disease should be considered as a diagnosis when faced with an orbital mass with extension to the paranasal sinuses, and a complete excision through a combined endonasal and orbital approach prevents recurrence in most cases. Key points: • First described case of maxillary sinus angiolymphoid hyperplasia with eosinophilia. • Maxillary sinus and orbital mass. • Combined endonasal and orbital approach.

Metastases to the nose and paranasal sinuses are unusual. These tumors are commonly seen in the 4th to 6th decades of life. The clinical presentation may be analogous to that of primary sino-nasal tumors. They usually present with common nasal and ocular symptoms due to which diagnosis may be missed and delayed. Hence, high level of suspicion is necessary for patients with known malignancies presenting with inconsistent or repeated nasal and ocular symptoms. Otorhinolaryngologists should be familiar with these metastases to paranasal sinuses from unusual primary elsewhere in the body, to evaluate and manage these tumors. Retrospective data was collected from the hospital records from 2020-2023. A total 14 cases of sino-nasal malignancies were identified. On further analysis three cases were found to be having distant metastases from primary sites such as kidney, breast and lymph nodes. We are reporting three metastatic malignancies. Each was systematically evaluated, confirming their origin as metastases from other primary sites. They were then managed appropriately.

Following the European Forum for Research and Education in Allergy and Airway Diseases (EUFOREA) treatment algorithm for chronic rhinosinusitis (CRS) with nasal polyps (CRSwNP), patients suffering from severe uncontrolled CRSwNP are recommended to receive oral corticosteroids, (revision) sinus surgery, systemic biologicals and/or aspirin treatment after desensitization (ATAD). Given the major differences in indications, outcomes, practical considerations, risks and costs of these key pillars of treatment, there is a growing need to define criteria for each treatment option and list the clinically relevant and major considerations for them. This EUFOREA document therefore provides an expert panel overview of the expected outcomes, specific considerations and (contra)indications of the five major treatment arms of severe uncontrolled CRSwNP: oral corticosteroids, primary and revision sinus surgery, biological treatment and ATAD. This overview of treatment considerations is needed to allow physicians and patients to consider the different options in the context of providing optimal and personalized care for severe uncontrolled CRSwNP. In conclusion, the five major treatment options for severe uncontrolled CRSwNP have intrinsic advantages, specific indications and considerations that are of importance to the patient, the physician and the society. This EUFOREA statement supports the unmet need to define criteria for the indication of every treatment pillar of CRSwNP. [ABSTRACT FROM AUTHOR]

Background: Priming is a psychological phenomenon where subconscious cues in the environment impact our behavioral responses in certain situations. Well studied in the worlds of business, marketing, and even politics, it is unclear how the priming phenomenon impacts patient perception of their own disease state nor how they report that perception using tools like the Sinonasal Outcomes Test (SNOT-22), used to measure that perception in chronic rhinosinusitis. Objective: To determine the impact of positive or negative priming on self-reported patient perception of their chronic rhinosinusitis disease using the SNOT-22 disease-specific quality of life instrument. Methods: Single-blind, randomized, prospective cohort pilot study of 206 consecutive adult patients with a clinical diagnosis of chronic rhinosinusitis presenting to a university rhinology clinic. Patients were randomized to receive "positive priming" (103) or "negative priming" (103) by reading a passage about the positive or negative aspects of chronic sinusitis and its treatment respectively. Patients were then asked to fill out the SNOT-22 and results between the two groups were compared. Results: The negative priming group had a higher median SNOT-22 score of 49 [IQR = 39] compared to the positive priming groups' score of 22 [IQR = 27], p < 0.0001), a difference of nearly three times the minimal clinical impactful difference (MCID). This effect was consistent regardless of age or sex of the patient. Subgroup analysis revealed a greater impact when priming was performed by the senior male attending regardless of patient age or sex (p < 0.001), while priming performed by the younger female research fellow had greater impact on older patients (>59 years, p = 0.001) and female patients (p = 0.003). Conclusions: Priming impacts how patient's perceive their chronic rhinosinusitis as determined by the SNOT-22. It is imperative that the rhinologist understand this when using this instrument in research applications and in clinical decision-making for patients. [ABSTRACT FROM AUTHOR]

Objective: To determine the association between time to elective endoscopic sinus surgery (ESS) and postoperative medication consumption and cost during a two-year follow up in patients with chronic rhinosinusitis without nasal polyps (CRSsNP). Materials and Methods: The authors reviewed medical records of patients treated with ESS after medical failure between 2009 and 2020 at the Songklanagarind Hospital. The patients were divided into three groups, early surgery at less than one year, mid-surgery at one to five years, and late surgery at more than five years. The number of postoperative visits, CRS-related medications, and costs were compared among the groups. Multivariate analysis was performed to estimate the relationships between the independent factors. Results: Sixty-nine patients were enrolled in the present study with 30.4% who underwent early surgery, 52.2% who were treated with midsurgery, and 17.4% who underwent late surgery. The number of 2-year postoperative intranasal corticosteroids (INCS) used, and CRS-related medication costs compared with the time to surgery were significantly different. The higher frequency of prescriptions for INCS use and CRSrelated medication costs were significantly different between the groups. Conclusion: Time to sinus surgery was associated with the 2-year postoperative INCS use and CRS-related medication costs. Early surgery, after the appropriate medical treatment failed, was a better prognostic predictor for reduced INCS use and medication costs after surgery and could be an effective option for improving postoperative inflammation control and managing CRS.

Aim: The aim of this study was to evaluate the safety and efficacy of the piezoelectric knife as a new tool for frontal beak surgery in patients with chronic rhinosinusitis (CRS) both in terms of imaging and perception of symptoms' outcomes. Materials and methods: The study involved 28 patients with CRS who underwent endoscopic sinus surgery (ESS) using a piezoelectric knife in the frontal recess region. Assessment of sinus imaging and patients' quality of life (QoL) was performed before and after surgery with the Lund-Kennedy and Lund-Mackay systems and the 22-item Sino-Nasal Outcomes Test (SNOT-22). Results: Median scores on the Lund-Kennedy and Lund-Mackay systems decreased within 24 weeks after surgery with piezo knife assistance by 4 and 5 points, respectively. QoL improved with SNOT-22 scores decreasing by 35.5 points. Conclusions: ESS with the piezoelectric knife used for frontal beak reduction turned out to be a safe procedure. In the studied group of patients, the improvement was observed in terms of imaging, patients' perceptions of symptoms, and QoL outcomes. Therefore, the piezoelectric knife might be a valuable supporting tool in ESS in patients with CRS, although further observation is needed. [ABSTRACT FROM AUTHOR]

Background: It is unclear whether chronic rhinosinusitis (CRS) endotypes show a differential response to endoscopic sinus surgery (ESS). We explored patient mucous inflammatory cytokine expression and associations with patient‐reported and clinically measured post‐operative outcome measures. Methods: Patients with CRS were prospectively recruited between 2016 and 2021 into a national multicenter, observational study. Mucus was collected from the olfactory cleft preoperatively and evaluated for 26 biomarkers using cluster analysis. Patient‐reported outcome measures included the 22‐item Sino‐Nasal Outcome Test (SNOT‐22) and Questionnaire of Olfactory Dysfunction (QOD). Additional clinical measures of disease severity included threshold, discrimination, and identification (TDI) scores using "Sniffin' Sticks" testing and Lund–Kennedy endoscopic score (LKES). Results: A total of 115 patients were clustered into type 2 inflammatory, non–type 2 inflammatory, noninflammatory, and two indeterminate clusters based on individual protein levels. Overall, the type 2 inflammatory cluster was found to have the highest mean improvement in both SNOT‐22 (−28.3 [standard deviation, ±16.2]) and TDI (6.5 [standard deviation, ±7.9]) scores 6 months after ESS. However, on average, all endotype clusters demonstrated improvement in all outcome measures after ESS without statistically significant between‐group differences in SNOT‐22 (p = 0.738), QOD (p = 0.306), TDI (p = 0.358), or LKES (p = 0.514) measures. Conclusions: All CRS endotype clusters responded favorably to surgery and showed improvements in patient‐reported and objective outcome measures. Thus, ESS should be considered a more generalized CRS therapy, and benefits appear to not be limited to specific endotypes. [ABSTRACT FROM AUTHOR]

Introduction: The treatment of nasal sinus diseases with Functional Endoscopic Sinus Surgery (FESS) is a well-established and popular method. This procedure is performed under general anaesthesia or local anaesthesia. Intentional induction of hypotension has helped limit intraoperative blood loss. A bloodless surgical field improves visibility and lowers the possibility of damaging nearby structures, achieved by reducing the baseline Mean Arterial Pressure (MAP) by 30% or maintaining MAP at 60-70 mmHg. Aim: To compare the efficacy of dexmedetomidine and Magnesium Sulphate (MgSO4) in producing hypotensive anaesthesia during FESS. Materials and Methods: This randomised clinical study was conducted at BLDE Shri BM Patil Medical College and Research Centre, Vijayapura, Karnataka, India, from January 2021 to July 2022. In this study, 70 patients, aged 18 to 60 years of either sex, admitted for FESS surgeries under general anaesthesia with American Society of Anaesthesiologists (ASA) Grade 1 and 2 were randomly divided into two groups: 35 patients in the dexmedetomidine group and 35 patients in the MgSO4 group. Dexmedetomidine was given to group D as a loading dose of 1 μg/kg, followed by an infusion of 0.5 μg/kg/h, and MgSO4 was given to group M as a loading dosage of 40 mg/kg, followed by an infusion of 15 mg/kg/h. MAP was kept above 65 mmHg during induced hypotension. Parameters studied included Heart Rate (HR), Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP), MAP. Data was analysed using International Business Machines (IBM) Statistical Package for Social Sciences (SPSS) Statistics Software Version 23.0. A p-value

Abstract Background Several biologics are now approved in the US as add-on treatments for chronic rhinosinusitus with nasal polyps (CRSwNP). This cross-sectional, retrospective, real-world study aimed to characterize treatment patterns and identify predictors of biologic use among patients with CRSwNP. Methods Adults in the Merative MarketScan Commercial and Medicare Supplemental Databases with medical claims for CRSwNP were identified June 2018–June 2019 (identification period [IP]). Patient characteristics were collated in the IP and treatment pattern data during the IP plus the following year (July 2019–June 2020; observation period [OP]). Data were stratified by sinus surgery and biologic use. Results Of the 5997 eligible patients identified (58% male, mean age 48.1 years), 10.7% (n = 642) used biologics during the OP. More biologic users had common respiratory conditions than non-users, particularly asthma (89.1% vs 35.0%; P

Data was analysed using International Business Machines (IBM) Statistical Package for Social Sciences (SPSS) Statistics Software Version 23.0. A p-value <0.05 was considered statistically significant. Results: The demographic profiles regarding age, gender, ASA grade, and duration of surgery in both groups were comparable and showed no significant differences. At 30 minutes of surgery, MAP in group D was found to be statistically lower than that in group M with a p-value of 0.0001. Dexmedetomidine induced a significant reduction in HR, which was statistically validated with a p-value of 0.004 at 15 minutes. A statistically significant reduction in MAP was found in group D compared to group M at the time of intubation and later at 10 minutes (p-value=0.005) and 15 minutes (p-value=0.006). Conclusion: The target MAP of 60-70 mmHg or a 30% reduction from the baseline MAP was achieved significantly earlier in group D as compared with group M. Group D had lower infusion dosages, better surgical field visibility, and caused less bleeding. The dexmedetomidine group experienced extended sedation and postoperative recovery.

Background: In the 52‐week Phase III SYNAPSE study, mepolizumab given every 4 weeks (100 mg subcutaneously) reduced nasal polyp (NP) size, improved symptoms and quality of life (QoL), and reduced corticosteroid use and number of sinus surgeries in patients with severe chronic rhinosinusitis with nasal polyps (CRSwNP), versus placebo. Because the durability of mepolizumab's efficacy after discontinuation is poorly understood in CRSwNP, the efficacy of mepolizumab after discontinuation was analyzed in severe CRSwNP, over a 24‐week follow‐up. Methods: Changes from SYNAPSE baseline to end of treatment (week 52) and end of follow‐up (week 76) were assessed for total endoscopic NP score, nasal obstruction and overall symptoms visual analog scale scores, and 22‐item Sino‐Nasal Outcome Test score. Time to first sinus surgery, time to first corticosteroid use, and geometric mean blood eosinophil counts (BECs) were also assessed. Results: Among 134 follow‐up patients, clinical improvements observed with mepolizumab versus placebo were partially evident 24 weeks after discontinuation despite BEC returning to baseline. The mean (95% confidence interval [CI]) change from baseline in NP score (week 52: −1.3 [1.8 to −0.9] vs. −0.3 [−0.6 to 0.1]; week 76: −1.2 [−1.6 to −0.7] vs. −0.1 [−0.5 to 0.3]) and the proportion of patients having sinus surgery (week 52: 4% vs. 25%; week 76: 9% vs. 31%) remained substantially improved with mepolizumab versus placebo. Mepolizumab‐associated improvements in overall symptoms, quality of life, and corticosteroid use versus placebo were partially sustained at week 76. Conclusion: Fifty‐two weeks of mepolizumab treatment is associated with sustained clinical benefits up to 24 weeks after discontinuation in patients with severe CRSwNP, which should be considered by physicians when making treatment decisions.

Background: Budesonide irrigations (BIs) are commonly used to control inflammation in chronic rhinosinusitis (CRS). In 2016 we reported an analysis of long‐term BI with regard to hypothalamic‐pituitary‐adrenal axis function. We present a follow‐up analysis in a larger cohort of patients with longer follow‐up. Methods: Patients were candidates for stimulated cortisol testing after regularly performing BI for CRS at least daily for ≥6 months. We retrospectively evaluated all patients who received stimulated cortisol testing at our center between 2012 and 2022. We correlated cortisol levels with the use of BI and other forms of corticosteroids. Results: We analyzed 401 cortisol test results in 285 patients. The mean duration of use was 34 months. Overall, 21.8% of patients were hypocortisolemic (<18 ug/dL) at first test. In patients who used only BI, the rate of hypocortisolemia was 7.5%, whereas in patients who also used concurrent oral and inhaled corticosteroids, the rate was 40% to 50%. Lower cortisol levels were associated with male sex (p < 0.0001) and concomitant use of oral and inhaled steroids (p < 0.0001). Duration of BI use was not significantly associated with lower cortisol levels (p = 0.701), nor was greater dosing frequency (p = 0.289). Conclusion: Prolonged use of BI alone is not likely to cause hypocortisolemia in the majority of patients. However, concomitant use of inhaled and oral steroids and male sex may be associated with hypocortisolemia. Surveillance of cortisol levels may be considered in vulnerable populations who use BI regularly, particularly in patients using other forms of corticosteroids with known systemic absorption.

Background: Trial data demonstrate that mepolizumab, a humanized anti‐interleukin 5 monoclonal antibody, is effective for patients with severe asthma and comorbid chronic rhinosinusitis (CRS) with nasal polyps. This real‐world, retrospective cohort study investigated mepolizumab for US patients with severe asthma and CRS with/without sinus surgery. Methods: IQVIA PharMetrics Plus claims data from baseline and follow‐up (12 months before and after mepolizumab initiation) were used to analyze three patient cohorts: cohort 1 (severe asthma only); cohort 2 (severe asthma + comorbid CRS without sinus surgery); and cohort 3 (severe asthma+comorbid CRS+sinus surgery), allowing for cross‐cohort comparisons. Results: The analysis included 495, 370, and 85 patients in cohort 1, cohort 2, and cohort 3, respectively. Systemic and oral corticosteroid use was lower for all cohorts after mepolizumab initiation. In cohort 3, asthma rescue inhaler and antibiotic use were lower during follow‐up than baseline. Asthma exacerbations were reduced by 28% to 44% comparing follow‐up versus baseline, with the largest reduction in cohort 3 (ratio of incidence rate ratio [RR] vs cohort 1: 0.76; p = 0.036). Reductions in oral corticosteroid claims were greater following mepolizumab initiation for cohort 3 versus cohort 1 (RR, 0.72; p = 0.011) and cohort 2 (RR, 0.70; p < 0.01). In cohorts 1 through 3, outpatient and emergency department visits were reduced by 1 to 2 and 0.4 to 0.6 visits annually, asthma‐related and asthma exacerbation–related total costs were reduced by $387 to $2580 USD, and medical costs were reduced by $383 to $2438 USD during follow‐up. Conclusions: Consistent with trial data, mepolizumab use in real‐world practice shows benefits across comorbid patient cohorts with more a pronounced impact in those with severe asthma+comorbid CRS + sinus surgery.

This research examines the advantages and disadvantages of 3D endoscopy compared to traditional 2D endoscopy for sinus surgery. It has been found that 3D endoscopy significantly improves depth perception, the brightness of the surgical field, and intraoperative visualization, making it particularly useful for training and understanding anatomy. Despite these benefits, 3D endoscopy can cause discomfort in surgeons, including dizziness, eye strain, and headaches. The development of automated visualization systems based on stereo cameras can enhance procedural accuracy. The use of personalized physical models created through rapid prototyping increases the effectiveness of training systems. However, the need to wear 3D glasses and the difficulty in cleaning the lenses remain issues. Future prospects include the application of such systems in telemedicine services for remote consultations. [ABSTRACT FROM AUTHOR]

Background: Intraoperative navigation allows for the creation of a real-time relationship between the anatomy imagined during diagnosis/planning and the site of surgical interest. This procedure takes place by identifying and registering trustworthy anatomical markers on planning images and using a point locator during the operation. The locator is calibrated in the workspace by placing a Dynamic Reference Frame (DRF) sensor. Objective: This study aims to calculate the localization accuracy of an electromagnetic locator of neuro-maxillofacial surgery, moving the standard sensor position to a different position more suitable for maxillofacial surgery. Materials and Methods: The upper dental arch was chosen as an alternative fixed point for the positioning of the sensor. The prototype of a bite support device was designed and generated via 3D printing. CT images of a skull phantom with 10 anatomical landmarks were acquired. The testing procedure consisted of 10 measurements for each position of the sensor: precisely 10 measurements with the sensor placed on the forehead and 10 measurements with the sensor placed on the bite support device. It also evaluated the localization error by comparing the two procedures. Results: The localization error, when the sensor was placed on the bite support device, was lower in the sphere located on the temporal bone. It was the same in the spheres located on the maxillary bone. The test analysis of the data of the new device showed that it is reliable; the tests are reproducible and can be considered as accurate as the traditional ones. In addition, the sensor mounted on this device has proven to be slightly superior in terms of accuracy and accuracy in areas such as the middle third of the face and jaw. Discussion and Conclusion: The realization of the bite support device allowed the sensor to change position concerning its natural site. This procedure allows us to explore structures, such as the frontal site, which were initially difficult to approach with neuronavigation and improves the approach to midface structures, already studied with neuronavigation. The new calibration, with the position of the sensor on the support device in the same reference points sphere, highlighted the reduction in the location error. We can say that the support proposed in this study lays the foundations for a new navigation approach for patients in maxillofacial surgery, by changing the position of the sensor. It has strong points in improving the localization error for some reference points without determining disadvantages both in the calibration and in the surgical impediment. [ABSTRACT FROM AUTHOR]

Background: Several biologics are now approved in the US as add-on treatments for chronic rhinosinusitus with nasal polyps (CRSwNP). This cross-sectional, retrospective, real-world study aimed to characterize treatment patterns and identify predictors of biologic use among patients with CRSwNP. Methods: Adults in the Merative MarketScan Commercial and Medicare Supplemental Databases with medical claims for CRSwNP were identified June 2018–June 2019 (identification period [IP]). Patient characteristics were collated in the IP and treatment pattern data during the IP plus the following year (July 2019–June 2020; observation period [OP]). Data were stratified by sinus surgery and biologic use. Results: Of the 5997 eligible patients identified (58% male, mean age 48.1 years), 10.7% (n = 642) used biologics during the OP. More biologic users had common respiratory conditions than non-users, particularly asthma (89.1% vs 35.0%; P < 0.001). Biologic users had fewer diagnostic services but more drug-related services than non-users. Only 11.6% of patients who had sinus surgery used biologics, with most (56.1%) having their first biologic dose before sinus surgery and 12.5% ≤ 30 days after. Oral corticosteroid (OCS) use was higher in biologic users than non-users (all patients: 68.8% vs 42.5%; P < 0.001) and in those with/without sinus surgery. Comorbidities, prior OCS/doxycycline use, and age (< 65 years) increased the odds of biologic use, with asthma increasing the odds 5.46 times (P < 0.001). Conclusions: Biologic use was more common before first/next sinus surgery and in patients with high unmet need, elucidating predictors of biologic use that could be used in clinical practice.

The Onodi cell is the most posterior ethmoid cell that pneumatized superiorly and laterally to the sphenoid sinus. Nearby are the internal carotid artery and the optic nerve canal. Understanding the intricate architecture of the skull base can help you perform endoscopic transsphenoidal and skull base procedures with less chance of damaging nearby structures. Therefore, it is absolutely essential to establish the prevalence and position of Onodi cells. Method 164 CBCT images of subjects aged 18 to 70 years with optimal diagnostic quality and area coverage satisfying the selection criteria without a history of maxillofacial fractures, pathologies, or anomalies involving the middle one-third of the face were analyzed. Results Onodi cells were observed in 71 (43%) of the 164 patients assessed. Onodi cells were identified in 42 (44.2%) males and 29 (42%) females. Out of 42 males with Onodi cell presentations, 19 exhibited pneumatization in the age group of 18-30 yrs, 13 in the age group of 31-50 yrs, and 10 in the age group of 51-70 yrs. In the case of females, 11 subjects exhibited Onodi cells in the age group of 10-30 yrs, 9 in the age group of 31-50 yrs, and 9 in the age group of 51-70 yrs. Conclusion Both male and female individuals in the current study had an elevated incidence of posterior ethmoidal air cells. Furthermore, this study shows a stronger identification of Onodi cells using CBCT as compared to CT and cadaveric dissection analyses. There is significant debate over the anatomy and location of the posterior ethmoidal pneumatization. As a result, the fields of otolaryngology and maxillofacial radiography encourage CBCT investigations of Onodi cells. [ABSTRACT FROM AUTHOR]

Background and Objectives: This study aims to establish the sheep head as a viable anatomical model for training in functional endoscopic sinus surgery through comprehensive anatomical examination and training-based assessment of participants' satisfaction. Materials and Methods: Participants were divided into three groups according to their prior experience in endoscopic sinus surgery; in total, 24 participants were included. Each participant in the study was assigned to perform the designated procedures on a single sheep's head. Following the completion of the procedures, each participant was provided with a 14-item comprehensive satisfaction questionnaire with a scale attributed from 1 to 5. The normality of distribution was checked by applying the Shapiro-Wilk Test. The Kruskal–Wallis test was applied to compare study group sentiment of agreement towards individual procedures. Results: No significant differences were noted between the answers of the different groups. For the resident group, the average satisfaction score was 4.09 ± 0.54; junior specialist group 4.00 ± 0.55; for the senior specialist group overall satisfaction average score was 4.2 ± 0.77. Conclusions: The sheep's head can be successfully used for learning and practicing manual skills and the use of instruments specific to functional endoscopic sinus surgery. Moreover, the sheep head model can be used for training in other diagnostic or surgical procedures in the field of otorhinolaryngology, such as endoscopy of the salivary glands, open laryngotracheal surgery, or in otologic surgery, but also in other different surgical fields such as neurosurgery, ophthalmology or plastic surgery. Despite the differences between the ovine model and human anatomy, it provides a resourceful and cost-effective model for beginners in endoscopic nasal surgery. [ABSTRACT FROM AUTHOR]

Background: Incidence of fungal rhinosinusitis has increased in recent few years. We investigated the differences in microbiological findings between patients with fungal and non-fungal rhinosinusitis by growing microbiological cultures from samples obtained from sinus surgery. Methods: Using the Chang Gung Research Database, we enrolled all chronic rhinosinusitis (CRS) patients who had ever undergone sinus surgery from 2001 to 2019 and had microbiological culture during sinus surgery. Enrolled patients were divided into fungal and non-fungal groups, based on fungal culture and surgical pathology. Results: A total of 898 patients were diagnosed with fungal rhinosinusitis and 2884 with non-fungal rhinosinusitis. The fungal group had a higher age distribution (56.9 ± 13.1 vs. 47.0 ± 14.9), a larger proportion of females (62.4% vs. 37.0%), more unilateral lesions (80.4% vs. 41.6%), a lower incidence of the need for revision surgery (3.6% vs. 6.0%, p = 0.004), and a higher proportion of Pseudomonas aeruginosa in the culture (14.3% vs. 4.6%, p < 0.001). Conclusions: This large-scale study showed that Pseudomonas aeruginosa are more commonly found in patients with fungal rhinosinusitis and in patients who needed revision surgery, suggesting that efforts aimed at eliminating Pseudomonas are needed in order to improve the disease outcomes of patients with fungal rhinosinusitis.

Introduction: Current scientific developments seem to allow for an "olfactory implant" in analogy to cochlear implants. However, the position and surgical approaches for electrical stimulation of the olfactory system are unclear. Methods: In a human anatomic cadaver study, we investigated different endoscopic approaches to electrically stimulate the olfactory bulb (OB) based on the following considerations: (1) the stimulating electrode should be close to the OB. (2) The surgical procedure should be as non-invasive and safe as possible and (3) as easy as possible for an experienced ENT surgeon. Results: In summary, the endoscopic intracranial positioning of the electrode via a widened ostium of the fila olfactoria or a frontal sinus surgery like a Draf IIb procedure is a good option in terms of patients' risk, degree of difficulty for ENT surgeons, and position to the OB. Endoscopic intranasal positioning appeared to be the best option in terms of patient risk and the degree of difficulty for ENT surgeons. Although a bigger approach to the OB using a drill and the combined intranasal endoscopic and external approach enabled a close placement of the electrode to the OB, they do not seem relevant in practice due to their higher invasiveness. Conclusion: The study suggested that an intranasal positioning of a stimulating electrode is possible, with placements beneath the cribriform plate, extra- or intracranially, applying elegant surgical techniques with low or medium risk to the patient and a close placement to OB.

Background: Postoperative epistaxis is a known possibility following endoscopic sinonasal surgery. Tranexamic acid (TXA) has been shown to reduce intraoperative blood loss and improve the visual field. This study evaluated the clinical efficacy of TXA when given at end of surgery to reduce postoperative bleeding. Methods: This randomized, double‐blinded placebo‐controlled trial was conducted from April to November 2021. Patients scheduled to undergo endoscopic sinus or nasal surgery were randomized to receive an intravenous dose of 1 g TXA or saline intraoperatively prior to extubation. A 10‐in. visual analog scale (VAS) was used to query patients regarding postoperative bleeding each day for 1 week. The medical record was examined to determine the need for additional evaluations or interventions for epistaxis. Results: Forty patients completed the study. The mean ± SD postoperative bleeding VAS for the TXA group on the day of surgery was not significantly different from the saline group (4.82 ± 2.18 in. vs. 5.03 ± 2.14 in., p = 0.8). There were no significant differences between treatment arms on any postoperative day through day 7 (0.67 ± 1.84 in. vs. 0.87 ± 0.99 in., p = 0.7), nor in the reduction in VAS compared to the respective baseline on the day of surgery. There were no significant differences in terms of additional interventions (e.g., additional evaluation in recovery, ED, or clinic, need for packing, or return to the operating room [OR]). Conclusion: Although TXA has previously demonstrated efficacy to reduce intraoperative bleeding during sinonasal surgery, when postoperative bleeding is already minimal at baseline, TXA does not appear to reduce it significantly further.

Keypoints: Extranodal NK/T‐cell lymphoma (ENKL) was the most common sinonasal lymphoma at our hospital.ENKL occurs at a younger age, and is more prevalent in the nasal cavity.ENKL had a lower Ann Arbor stage, and a better prognosis than diffuse large B‐cell lymphoma (DLBLC). [ABSTRACT FROM AUTHOR]

IntroductionAspirin desensitization (AD) and aspirin therapy after desensitization (ATAD) are therapeutic interventions for patients with aspirin-exacerbated respiratory disease (AERD). Our aim is to investigate whether its addition to endoscopic sinus surgery (ESS) improves the overall prognosis of the disease.MethodsA systematic review of the current literature including adult patients with a positive diagnosis of AERD undergoing endoscopic sinus surgery (ESS) in the context or in absence of upper airway comorbidity, prior to AD + ATAD.ConclusionThis review concludes that the surgical approach is beneficial in AERD, but its effects are short—lived. Surgery should be considered initially with subsequent AD + ATAD in AERD patients, due to the sustained improvement achieved compared to those receiving ESS alone.

Complications of endoscopic sinus/nasal turbinate surgery include postoperative hemorrhage, synechiae formation, and poor wound healing. Our primary objectives were to evaluate whether a topical hydrogel based on self-assembling RADA16 peptides: i) reduces bleeding and synechiae formation, and ii) supports wound healing, using a sheep nasal surgery model. Thirty sheep received endoscopic surgery-created bilateral nasal mucosal injuries on the middle turbinate/opposing septum. Injuries were randomly assigned RADA16, Gelatin-thrombin, or no treatment. Outcomes included intra-operative hemostasis, scar tissue/synechiae formation and wound healing at 2 weeks and the 6-week study terminus, and histopathology. Intra-operative hemostasis time improved with RADA16 and Gelatin-thrombin versus Control wounds (139.7±56.2 s, 145.4±58.1 s, and 224.0±69.9 s, respectively; p < 0.0001 for both comparisons). Two-week synechiae scores (maximum 4 points) were similar in Controls (2.9±1.8 points) and Gelatin-thrombin (3.1±1.6 points) wounds (p > 0.05), but were reduced in RADA16 sites by 91% versus Controls and 92% versus Gelatin-thrombin treatment (0.3±0.6 points; p < 0.0001 for both comparisons). Six-week synechiae scores were similar in Control (1.1±1.7 points) and Gelatin-thrombin (1.7±2.0 points) wounds (p > 0.05), but reduced 100% in RADA16-treated wounds. Synechiae occurred in fewer RADA16-treated sites at 2 weeks (20%) versus Gelatin-thrombin (80%) and Controls (75%; p < 0.01) and at 6 weeks (0%, 50% and 35%, respectively; p < 0.01). RADA16 was associated with significantly lower 6-week histopathology scores, driven by reduced submucosal fibrosis and angiogenesis. Although RADA16 and Gelatin-thrombin similarly accelerated hemostasis in this sheep endoscopic sinus surgery model, only RADA16 reduced postoperative synechiae formation at 2 weeks with an absence of synechiae at 6 weeks. Histology suggested RADA16 enhanced mucosal regeneration. [ABSTRACT FROM AUTHOR]

Chronic rhinosinusitis with nasal polyps (CRSwNP) compromises respiratory function, sleep, concentration, work capacity, and quality of life, generating high costs for patients and health systems. The aim of the study was to analyze the cost utility of Dupilumab compared to endoscopic sinus surgery for patients with CRSwNP. We developed a model-based cost–utility analysis from the perspective of the Colombian health system to compare Dupilumab vs. endoscopic nasal surgery in patients with difficult-to-treat CRSwNP. Transition probabilities were extracted from the published literature about CRSwNP, and costing was based on local tariffs. We performed probabilistic sensitivity analysis for outcomes, probabilities, and costs (10.000 Monte Carlo simulations). The cost of dupilumab ($ 142.919) was 7.8 times higher than nasal endoscopic sinus surgery ($ 18.347). In terms of quality-adjusted life years (QALYs), surgery generates better results than Dupilumab: 11.78 vs. 9.05 QALYs. From the perspective of the health system, endoscopic sinus surgery for the management of CRSwNP is a dominant alternative in all the analyzed scenarios compared to the use of Dupilumab. From a cost–utility point of view, the use of dupilumab should be considered when the patient requires multiple surgeries or when there is a contraindication for surgery performance.

Abstract Objective Endoscopic ear surgery (EES) is a growing and well-recognized field in the modern era. EES had a stepwise journey of development. This journey is pretty comparable to the endoscopic sinus surgery development. Methods Online literature search was performed to give a concise review on the development and recent applications of EES and in addition to clarify the reported advantages and disadvantages of EES. Results EES has a more recent application than ESS that started decades after endoscopic sinus surgery (ESS). The use of endoscope in ear surgery gives a wide-angled detailed view of the middle ear structures. It gives the ability to look around the corners offering less disease persistence than the microscopic approaches. EES is useful in cases of narrow and angled external auditory canal as it bypasses the narrowest segment of EAC. However, it lacks the 3D perception and enables one hand surgery which could be difficult to manage bleeding. Applications of EES extended from tympanoplasty, stapedotomy, cholesteatoma surgery, and middle ear ventilation in chronic inflammatory conditions to the neurotologic applications in lateral skull base surgery. Conclusion EES is an extremely growing field with many applications in otology and neurotology. The advantages of endoscopic applications outweigh the disadvantages. It has a stepwise learning curve and offer better teaching ability.

Objectives: Nasal saline irrigation is the corner stone of postoperative care after functional endoscopic sinus surgery (FESS) for chronic rhinosinusitis (CRS). However, intrasinus penetration of the saline solution can be challenging and may require difficult head position, particularly for the frontal sinus. Our aim was to evaluate a novel device for direct intrasinus self-irrigation, usable at home for both maxillary and frontal sinus. Methods: Thirty devices were implemented in 23 patients: in the maxillary sinus for 18 patients and in the frontal sinus for 5 patients. The device was removed after 7 days on average (5-10 days), and nasal saline irrigation was carried on with a squeeze bottle for 6 weeks. Retrospective evaluation of the device included: device-related complication, patient satisfaction, and ostial or middle turbinate synechiae at 3 months. Results: No device-related complication (obstruction, displacement, infection, bleeding) occurred. Twenty-one (91.3%) patients were satisfied with the device. Two patients required the help of a nurse for irrigation. No ostial of middle turbinate synechiae was visualized at 3 months. This new endonasal device enables direct intrasinus self-irrigation after FESS for CRS. Conclusion: This preliminary study showed that this device is safe and easy to use. However, further investigations are required to assess its potential role to reduce the risk of synechiae and revision surgery. [ABSTRACT FROM AUTHOR]

Introduction In patients with chronic rhinosinusitis, conservative interventions with extended medical trials are often attempted prior to procedural treatment. Balloon sinuplasty (BSP) is an established procedure for symptomatic relief from chronic rhinosinusitis. However, data suggesting the suboptimal efficacy of prolonged medication management trials, prior to BSP, is lacking. Objectives The purpose of this study was to evaluate the efficacy of prolonged medication management trials, prior to BSP, for patients with chronic rhinosinusitis. Methods A retrospective review was performed for all adults with chronic rhinosinusitis who received extended medical management prior to their BSP at two outpatient clinics, from November 1, 2013, to June 31, 2018. The patients' Sino-Nasal Outcome Test (SNOT) scores were compared between baseline, post-medication trials, and post-BSP. Results The SNOT scores of a total of 64 patients were collected. Overall, patients showed a significant worsening of symptoms during the medication management trials from baseline (p = 0.002126) but significant improvement of symptoms after undergoing BSP (p < 0.0001). Conclusion The patient symptom burden worsened and prolonged during medication management trials. The BSP procedure alone showed significant improvement in the quality of life for chronic rhinosinusitis patients, when considering their SNOT scores. The worsening of patients' symptoms during medication management may invalidate the necessity of prolonged medication management trials. [ABSTRACT FROM AUTHOR]

Purpose: In the era of precision medicine, target-therapy with monoclonal antibodies (mAb) has enabled new treatment options in patients affected by eosinophilic granulomatosis with polyangiitis (EGPA). Nevertheless, sometimes unsatisfactory results at a nasal level may be observed. The aim of this study is to describe reboot surgery as a potential adjuvant strategy in multi-operated, yet uncontrolled EGPA patients treated with Mepolizumab. Methods: We performed reboot surgery on EGPA patients with refractory CRSwNP. We obtained clinical data, nasal endoscopy, nasal biopsy, and symptom severity scores two months before surgery and 12 months after it. Computed tomography (CT) prior to surgery was also obtained. Results: Two patients were included in the study. Baseline sinonasal disease was severe. Systemic EGPA manifestations were under control, and the patients received previous mepolizumab treatment and previous surgery with no permanent benefits on sinonasal symptoms. Twelve months after surgery, nasal symptoms were markedly improved; endoscopy showed an absence of nasal polyps and there were fewer eosinophils at histology. Conclusions: We presented the first experience of two EGPA patients with refractory CRSwNP who underwent non-mucosa sparing (reboot) sinus surgery; our results support the possible adjuvant role of reboot surgery in this particular subset of patients.
