RESUMO
OBJECTIVE: To elucidate the effectiveness of a 30-degree anteriorly tilted coronal CT in visualizing the anterior wall of the sphenoid sinus. METHODS: Medical records and CTs of patients who underwent septoplasty, inferior turbinectomy, or endoscopic sinus surgery were reviewed. We evaluated the visibility of the anterior wall of the sphenoid sinus on conventional coronal CT scans and categorized its orientation. We then created anteriorly tilted coronal CT images to evaluate its improved visibility. RESULTS: A total of 129 patients were evaluated. While conventional coronal CT scans fully visualized the anterior wall of the sphenoid sinus in cases with an Onodi cell, 17.7% remained unidentified when the Onodi cell was absent. However, anteriorly tilted coronal CT scans consistently identified the anterior wall regardless of the presence of an Onodi cell. CONCLUSION: Our study highlights the effectiveness of anteriorly tilted coronal CT scans in consistently visualizing the anterior wall of the sphenoid sinus, regardless of the presence of an Onodi cell. It is possible that some other structures may become less identifiable on anteriorly tilted coronal CT.
RESUMO
Background and Aims: Postoperative pain can impede functional recovery and delay hospital discharge after functional endoscopic sinus surgery (FESS). The study aimed to assess the efficacy of ultrasound (USG)-guided suprazygomatic maxillary nerve block (SZMNB) for postoperative pain in FESS. Methods: Forty-eight adult patients between 18 and 65 years of age with American Society of Anesthesiologists physical status I and II and scheduled to undergo FESS were enroled in this randomised controlled study. Patients were randomly allocated to either receive USG-guided SZMNB with general anaesthesia (n = 24) or general anaesthesia alone (n = 24). The numerical rating scale (NRS) pain score in the immediate postoperative period was recorded as the primary outcome. A total of 24 h postoperative rescue analgesic consumption, surgeon satisfaction score, postoperative haemodynamics, and postoperative complications were noted as secondary outcomes. Results: The median (interquartile range) of the NRS pain score in the immediate postoperative period was 0 (0-0.25)[95% confidence interval (CI): 0, 0.08] in the block group compared to 2 (1.75-3) [95% CI: 1.60, 2.40] in the control group, P < 0.001]. Pain scores were significantly reduced at all time intervals till 24 h after surgery (P < 0.001). None of the patients required rescue analgesia in the block group. In contrast, eight patients required diclofenac 75 mg intravenous as rescue analgesia within 1 h of surgery and ten patients within 1-6 h of surgery in the control group. Other secondary outcomes were comparable between groups (P > 0.05). Conclusion: The USG-guided SZMNB provides excellent postoperative analgesia for patients undergoing FESS without significant side effects.
RESUMO
Background: We developed a technique to preserve the entire nasolacrimal duct and inferior turbinate, by swinging the nasolacrimal duct upward and the inferior turbinate backward; that is, a nasolacrimal duct and inferior turbinate swing technique for sinonasal inverted papilloma of the maxillary sinus. In this study, we evaluated the long-term results of this technique. Methods: A retrospective analysis was performed on the data for 53 consecutive pathologically confirmed inverted papilloma patients who were treated using nasolacrimal duct and inferior turbinate swing technique. The frequency of recurrence, the degree of nasolacrimal duct and inferior turbinate preservation, and the frequency of adverse events were assessed. Results: The median follow-up period was 51 months (mean 62.5 months; range 10-187 months). No cases of recurrence within the maxillary sinus were observed among the cases treated using this technique, whereas three (5.7%) of the 53 cases experienced recurrence in areas other than the maxillary sinus. We could preserve the nasolacrimal duct in all cases. On the other hand, the inferior turbinate was resected during surgery in one case. No epiphora, dacryocystiits, numbness of the cheek, or collapse of the ala of the nose was observed. Conclusion: This nasolacrimal duct and inferior turbinate swing technique method is a safe and effective method for the excision of primary or recurrent inverted papilloma and demonstrates low rates of recurrence and complications.
RESUMO
The article explores the understudied pathophysiology of odontogenic sinusitis (ODS) development as a result of oral surgical complications such as oroantral communication (OAC) or fistula (OAF), maxillary sinus bone grafting, and dental implantation. A temporary OAC presents most often after dental extraction, especially with posterior maxillary teeth, though can happen with any oral surgical intervention. Maxillary sinus augmentation can also cause ODS, and while the pathophysiology is incompletely understood, it may be related to OAC/OAF formation or bone graft infection. Dental implants may also lead to ODS either via displacement into the sinus, partial protrusion into the sinus, or peri-implantitis.
RESUMO
Objectives Virtual reality (VR) is an increasingly valuable teaching tool, but current simulators are not typically clinically scalable due to their reliance on inefficient manual segmentation. The objective of this project was to leverage a high-throughput and accurate machine learning method to automate data preparation for a patient-specific VR simulator used to explore preoperative sinus anatomy. Methods An endoscopic VR simulator was designed in Unity to enable interactive exploration of sinus anatomy. The Saak transform, a data-efficient machine learning method, was adapted to accurately segment sinus computed tomography (CT) scans using minimal training data, and the resulting data were reconstructed into three-dimensional (3D) patient-specific models that could be explored in the simulator. Results Using minimal training data, the Saak transform-based machine learning method offers accurate soft-tissue segmentation. When explored with an endoscope in the VR simulator, the anatomical models generated by the algorithm accurately capture key sinus structures and showcase patient-specific variability in anatomy. Conclusion By offering an automatic means of preparing VR models from a patient's raw CT scans, this pipeline takes a key step toward clinical scalability. In addition to preoperative planning, this system also enables virtual endoscopy-a tool that is particularly useful in the COVID-19 era. As VR technology inevitably continues to develop, such a foundation will help ensure that future innovations remain clinically accessible.
RESUMO
OBJECTIVES: The aim of this manuscript is to analyse a diagnostic protocol to select correctly patients with Rhinogenic Headache Contact Point (RH) and to investigate the effect of surgical treatment and medical therapy in pain relief. METHODS: A prospective no-randomized study selected adult patients with headache and nasal alteration at CT exam or endoscopic vision with positive response to test with nasal spray with corticosteroids and antihistamine or/and local anesthesia test to the contact points. MIDAS score, intensity score, daily duration of symptoms, frequency of headache in the last month were collected in patients who performed surgery and in patients who performed medical therapy. RESULTS: Following the inclusion, 415 patients were selected for this study. 302 patients performed nasal surgery (septoplasty, turbinoplasty and/or endoscopic surgery with centripetal technique), 113 performed medical therapy. There was a statistically significant improvement in MIDAS score, intensity score, daily duration of symptoms, frequency of headache in the last month in patients who performed surgery and in patients who performed medical therapy. Regarding the comparison between patients who performed surgery (Group A) and patients who performed only medical therapy for RH (Group B), better outcomes were obtained by Group A. Considering the daily life handicap index, the lowest handicap was obtained in Group A. CONCLUSION: This study demonstrates that surgery, using in some cases centripetal technique, gives an improvement statistically significant than medical therapy in RH. The use of nasal spray with corticosteroids and with anti-histamine is a good method in the diagnosis of RH, especially in patients with anatomical variants such as concha bullosa, agger nasi cells and Haller cells.
RESUMO
OBJECTIVE: Evaluating the possibility of predicting chronic rhinosinusitis with nasal polyps (CRSwNP) disease course using Artificial Intelligence. METHODS: We prospectively included patients undergoing first endoscopic sinus surgery (ESS) for nasal polyposis. Preoperative (demographic data, blood eosinophiles, endoscopy, Lund-Mackay, SNOT-22 and depression PHQ scores) and follow-up data was standardly collected. Outcome measures included SNOT-22, PHQ-9 and endoscopy perioperative sinus endoscopy (POSE) scores and two different microRNAs (miR-125b, miR-203a-3p) from polyp tissue. Based on POSE score, three labels were created (controlled: 0-7; partial control: 8-15; or relapse: 16-32). Patients were divided into train and test groups and using Random Forest, we developed algorithms for predicting ESS related outcomes. RESULTS: Based on data collected from 85 patients, the proposed Machine Learning-approach predicted whether the patient would present control, partial control or relapse of nasal polyposis at 18 months following ESS. The algorithm predicted ESS outcomes with an accuracy between 69.23% (for non-invasive input parameters) and 84.62% (when microRNAs were also included). Additionally, miR-125b significantly improved the algorithm's accuracy and ranked as one of the most important algorithm variables. CONCLUSION: We propose a Machine Learning algorithm which could change the prediction of disease course in CRSwNP.
RESUMO
OBJECTIVE: The frontal sinus remains a challenging site for irrigation due to its position relative to the nostril and ethmoid sinus. This study aims to summarize the necessary factors for efficient irrigation of the frontal sinus after endoscopic sinus surgery (ESS) among patients with chronic rhinosinusitis (CRS). METHODS: Using Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, a systematic literature review was conducted on PubMed, Scopus, and Cochrane databases to identify studies assessing the effect of frontal sinus irrigation in patients with CRS, cadaver models, or 3D-printed models of the sinonasal cavity after ESS. RESULTS: Of the initial 206 abstracts reviewed, 18 full-text articles were included. The degree of the frontal sinus ostium opening after ESS was found to be associated with the efficacy of frontal sinus irrigation. More extensive frontal sinus surgeries tended to increase frontal sinus penetration. A Draf IIA procedure was identified as the minimum standard to achieve sufficient irrigation in the frontal sinus. Due to decreased backpressure in the nasal passage, increasing septectomy in Draf III did not significantly improve irrigation delivery. Squeeze bottles achieved significantly higher irrigation flow in the frontal sinus than syringes and pulsating devices. Large-volume irrigation devices provided better irrigation for the frontal sinus by entering or flushing the entire frontal sinus. The head position influenced the frontal sinus irrigation by altering the ostia position relative to fluid flow and vertical height of the frontal sinus during irrigation. While the vertex down head position was likely to enhance frontal sinus irrigation, the comfort of the head position and patient compliance should be considered. CONCLUSION: Elements for optimization of frontal sinus irrigation are a minimum of a Draf IlA procedure for frontal sinus dissection, use of large-volume irrigation, and vertex down head positioning. Developing comfortable head positions with high frontal sinus irrigation efficiency would increase patient compliance and improve outcomes. LEVEL OF EVIDENCE: NA.

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.

RESUMO
INTRODUCTION: Chronic rhinosinusitis (CRS) is a chronic inflammatory disease of nasal and paranasal sinus mucosa where symptomatology has continued beyond 12 weeks. Manuka honey is made by bees that pollinate the native leptospermum scoparium bush (tea tree). Baby shampoo is a commercially available liquid solution containing multiple chemical surfactants that can act as a mucolytic and an antimicrobial agent. MATERIALS AND METHODS: Fifty patients diagnosed with CRS were taken to be part of study. The modes of comparison used were the Rhinosinusitis Disability Index (RSDI) and a self-formulated Nasal Crusting Score (NCS). Individuals in Group A were given 5% Manuka Honey for nasal douching in both nasal cavities and those in Group B were given 10% Baby Shampoo. OBSERVATIONS AND RESULTS: The average RSDI scores in Group A before & after intervention were 75.40 and 30.04, an improvement of 60.15%. The same parameters in Group B was found to be 77.36 and 37.36, an improvement of 51.70%. The NCS improved by 83.46% in the Group A and by 77.61% in Group B between POD-2 and POD-5. CONCLUSION: As per literature available, both Manuka Honey and Baby Shampoo have improved the outcomes of Quality of Life and airway after FESS. We found that Manuka Honey is superior in clearing crusts and achieving better symptom clearance post FESS. We also present our self-formulated Nasal Crusting Score which can be used in further practice for better understanding of nasal airway.
RESUMO
Acute invasive fungal sinusitis (AIFS) is an aggressive disease with significant mortality and morbidity. Surgical debridement is a mainstay of treatment. However, orbital involvement may limit its efficacy and is an independent risk factor for mortality. Traditionally, orbital exenteration has been utilized in cases with orbital invasion and ophthalmoplegia or vision loss. Retrobulbar liposomal amphotericin B injection may improve disease control and has the potential to spare the morbidity associated with exenteration. In this video article, we document the use of serial endonasal debridement with retrobulbar injections to salvage the eye in a patient with significant orbital involvement. A 28-year-old immunocompromised female patient presented with acute onset restricted right extraocular movement, progressive orbital pain, V2 trigeminal numbness, and 20/40 vision. The patient underwent recurrent debridement and retrobulbar injections of liposomal amphotericin B. Her serial exams, including changes in extraocular muscle appearance and gradual improvement in extraocular movement, were documented. The exam six months after initial presentation demonstrated 20/20 vision, minimal extraocular movement restriction, and proper healing of the orbit and ethmoid. The salvage of the patient's orbit suggests that liposomal amphotericin B injections with debridement may be a viable treatment alternative in patients with acute invasive fungal sinusitis and orbital involvement.
RESUMO
OBJECTIVE: The objective of this study was to explore the educational utility of virtually augmented surgical navigation (VASN) in simulation training for endoscopic sinus surgery. STUDY DESIGN: Prospective trial using within-subjects design. SETTING: Single academic institution. METHODS: Otolaryngology trainees (n = 15) were enrolled in a prospective trial of repeated measures. Participants performed unilateral functional endoscopic sinus surgery (FESS) on a 3-dimensional-printed sinus model without instruction. Participants then underwent educational intervention incorporating VASN tools-featuring anatomic overlay delineations, virtual planning points, proximity alerts, digital measurements, as well as artificial intelligence-generated endoscopic viewpoints. With the VASN tools activated, participants then performed FESS on the contralateral side of the model. Primary outcomes of interest included number of major complications, time to complete anterior fess, steps completed, and technical skills score. Descriptive statistics were performed to describe participant characteristics and bivariate analysis were used to evaluate differences in subjective and objective outcome measures. RESULTS: A majority (93%) of residents strongly agreed that simulation intervention improved their confidence in surgical skills related to FESS. Complications decreased from 13 instances to 3 following interventions. Initial technical skills score of 45.2 increased to 54.4 postintervention (P < .0001) and global score also improved by 4.6 points on average (P < .001). Time to anterior FESS decreased from 1356 to 915 seconds (P = .006) and average number of completed surgical steps increased from 3.3 to 4.6 (P < .001). CONCLUSION: This simulation study contributes to growing evidence supporting utility of advanced technology in surgical education. Results suggest that VASN serves as a beneficial adjunct in FESS simulation training.
RESUMO
BACKGROUND: In 2013, Japan established a standardized classification system for categorizing endoscopic sinus surgery (ESS) into types I-V, yet no evaluation has been conducted thereof. OBJECTIVE: We assessed the ESS trends and status in Japan, focusing on outpatient and inpatient surgeries. MATERIAL AND METHODS: This descriptive retrospective cohort study used Japan's National Database of Health Insurance Claims and Specific Health Checkups between 2014 and 2021. The distribution of ESS types I-V and outpatient and inpatient surgeries was analysed, along with age groups and regional differences, focusing on ESS type III. RESULTS: Overall, 427,813 ESS procedures were performed, with types III and IV being most common. Outpatient ESS type III increased substantially compared to inpatient surgeries. Younger individuals favoured outpatient ESS type III over inpatient surgeries, with substantial regional variations across prefectures. CONCLUSIONS AND SIGNIFICANCE: The adoption of a standardized ESS classification in Japan has facilitated a detailed understanding of surgical trends. The shift toward outpatient surgeries, especially for type III ESS, aligns with global trends toward minimally invasive procedures and reflects changing patient preferences and healthcare delivery practices. Consequently, continuous monitoring and research are crucial for adapting surgical practices to the evolving healthcare needs and patient expectations.
RESUMO
Nasal irrigation is crucial following endoscopic sinus surgery (ESS), especially for managing chronic rhinosinusitis (CRS). This study assessed the effectiveness of N-acetylcysteine (NAC) irrigation during the post-ESS period of patients with CRS without nasal polyposis. In this prospective, single-blind randomized controlled trial, 49 patients (NAC, n = 24; saline, n = 25) undergoing ESS were assigned to receive either NAC or saline irrigations twice daily for a month. The preoperative and postoperative assessments conducted included Lund-Macka (LM) and Lund-Kennedy (LK) endoscopic scores, the Nasal Obstruction Symptom Evaluation (NOSE) scale, and the Sino-Nasal Outcome Test-20 (SNOT-20). At 2 weeks, 1 month, and 3 months after the operation, endoscopic findings and symptoms were evaluated. Both groups showed no differences in age, sex, LM and LK scores, NOSE scale, and SNOT-20 preoperatively. In terms of the endoscopic findings regarding the sinonasal mucosa after ESS, the NAC group had slightly lower scores 2 weeks, 1 month, and 3 months after the operation, but this difference was not statistically significant. The NAC group showed significant improvement in VAS scores, namely, postnasal drip (1.0, p = 0.041), smell dysfunction (0.8, p = 0.003), and crust (1.5, p = 0.034), compared to the control group's scores of 2.6, 4.7, and 3.6, respectively, 2 weeks after the operation, although no significant differences were observed in VAS scores for any symptoms 1 and 3 months after the operation. NAC was well tolerated, and no adverse events were reported. NAC irrigation showed benefits over saline irrigation in terms of improving postnasal drip, smell dysfunction, and crust after ESS for CRS without nasal polyposis in the immediate postoperative period.
RESUMO
BACKGROUND: Allergic fungal sinusitis (AFS) is a form of paranasal mycosis that often involves bone destruction and can extend into the orbit and anterior skull base. Intracranial and intraorbital involvement are published but not both in each included patient of a series. The purpose of the present study was to review cases of extensive AFS with orbital or/and skull base erosion, including the presenting symptoms, patient socioeconomic background, imaging features, surgical technique, and post-operative outcomes. METHODS: The records of 30 patients with the histological diagnosis of AFS and both intracranial and intraorbital involvement were reviewed. RESULTS: The average age of the patients was 25.2 years. 83 % of patients were male. 70 % were African American. 66 % of patients had Medicaid or were uninsured. Presenting symptoms were headaches (80 %), nasal obstruction (33 %), proptosis (40 %), vision change (23 %), facial pressure (10 %), and decreased sense of smell (7 %). 100 % of patients had bone erosion observed on computerized tomography scans with disease extending intracranially through the anterior skull base or posterior wall of the frontal sinus along with disease that eroded through the lamina papyracea. All patients had failed medical management. All patients underwent surgery by Otolaryngology, Ophthalmology, and Neurosurgery with transnasal endoscopic approaches and orbitotomy. 80 % also underwent a bifrontal craniotomy for removal of intracranial extradural disease with cranialization. 53 % of patients had orbital implants remaining after surgery; 23 % had nasal stents. There were no postoperative cerebrospinal fluid leaks. Average hospital stay was 4.8 days. Preoperatively, 13 % of patients underwent allergy testing. 94 % saw an Allergist postoperatively. 21 % required follow up surgery. CONCLUSIONS: A team approach of Otolaryngologists, Ophthalmologists, and Neurosurgeons is recommended for this slowly growing but locally destructive disease. Most patients with AFS will present with headaches and nasal obstruction. While most cases of AFS can be successfully managed with transnasal endoscopic techniques, orbitotomy and craniotomy represents an effective treatment for severe AFS cases with extensive intracranial and intraorbital involvement. This disease is found most commonly in young African American males and in the underinsured.
RESUMO
Chronic rhinosinusitis (CRS) is characterized by chronic inflammation of the sinonasal mucosa, affects over 12% of the US population, and costs over $20 billion annually. CRS can be divided into two major phenotypes based on whether nasal polyps are present (CRSwNP) or absent (CRSsNP). This grand rounds review will discuss the clinical approach to patients with CRSwNP, including typical presentations, work-up, and currently available treatment options. Tools that physicians can utilize to assess subjective sinonasal symptoms, as well as objective measures of disease, will be reviewed. Additional focus will be on recognizing clinical comorbidities commonly associated with CRSwNP, including asthma, bronchiectasis, allergic rhinitis, and non-steroidal anti-inflammatory drug-exacerbated respiratory disease (NSAID-ERD). Clinical outcomes can be improved by providing a comprehensive approach to evaluating (and managing) patients with CRSwNP.
RESUMO
The lateral recess of a well-pneumatized sphenoid sinus is challenging to access surgically. Traditional methods require the use of multiple angled endoscopes and curved instruments which may limit visualization. We describe a prelacrimal-transpterygoid/maxillary approach which offers direct access to this region with a 0° endoscope. Laryngoscope, 2024.
RESUMO
Silent sinus syndrome (SSS) is a rare condition characterized by the collapse of the maxillary sinus and the sinking of the eye socket (enophthalmos). Only around 100 cases of SSS have been reported so far. The underlying cause of this condition is the chronic obstruction of the osteomeatal complex, which leads to sinus contraction. In this case, we present a novel finding linking SSS with granulomatosis with polyangiitis (GPA). The patient described is a 39-year-old male who was diagnosed with SSS after a prolonged period of sinus pressure, headaches, epistaxis, and generalized congestion. Additionally, the patient reported a significant autoimmune history, including a previous occurrence of ANCA-mediated glomerulonephritis. Surgical intervention revealed the presence of significant granulation tissue, while histopathological examination identified areas of necrosis, vasculitis, and multinucleated giant cells consistent with GPA. This finding was further supported by the detection of positive blood c-ANCA. This case is particularly noteworthy as it is the first reported instance of GPA causing SSS. It serves as an excellent example to illustrate the underlying pathophysiology of SSS.
RESUMO
INTRODUCTION: This is the first systematic review and meta-analysis to investigate the effectiveness of the nasal airflow-inducing maneuver (NAIM) in olfactory rehabilitation for total laryngectomy (TL) patients. METHODS: We conducted a systematic literature search following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The inclusion criteria required that patients must have undergone a TL with subsequent NAIM training for at least 2 weeks and olfactory evaluation. The impact of NAIM on olfactory outcomes compared to that at baseline was measured. Olfactory measures included the Sniffin' Sticks Test, Smell Disk Test, Scandinavian Odor Identification Test, and Quick Odor Detection Test. The primary outcome measures were the proportion of patients with normosmia at baseline and after intervention. RESULTS: Seven studies from 2000 to 2023 comprising a total of 290 TL patients met the inclusion criteria. The meta-analysis revealed that prior to intervention, the pooled proportion of patients with normosmia was 0.16 (95% confidence interval [CI]: 0.09â0.27, p = 0.01). After intervention, the same proportion increased to 0.55 (95% CI: 0.45â0.68, p = 0.001). Among the included patients, 88.3% were initially anosmic or hyposmic, which was reduced to 48.9% after NAIM practice, with 51.1% achieving normosmia. The percent improvement was not found to be significantly associated with the timing of intervention post-TL (p = 0.18). CONCLUSIONS: NAIM increased the proportion of patients who achieved normosmia in TL patients. NAIM stands out as a safe, easily teachable maneuver with promising results. Further efforts are warranted to provide specific recommendations and guidelines for the use of NAIM in clinical practice.
RESUMO
Introduction: Recent evidence recommends the use of biologics in patients with severe uncontrolled type 2 chronic rhinosinusitis with nasal polyp (CRSwNP) owing to its propensity for recurrence after functional endoscopic sinus surgery (FESS). Among the type 2 biologics used for the treatment of nasal polyps, dupilumab (Dupi, anti-IL-4) exhibited superior efficacy and safety in indirect comparison studies. Objective: This study aimed to evaluate the objective and subjective outcomes of patients with CRSwNP treated with and without adjuvant Dupi therapy after FESS. Methods: Adult patients with type 2 CRSwNP who underwent FESS with adjuvant Dupi after surgery were enrolled. A matched control group without adjuvant Dupi therapy were recruited during the same period. All patients underwent nasal endoscopy and completed the sinonasal outcome test-22 questionnaire evaluations at baseline and 3 months after surgery. Results: A total of 10 patients who received postoperative adjuvant therapy with Dupi and 20 patients who underwent surgery only were included. Patients with add-on Dupi therapy had significantly higher eosinophil cationic protein levels in the serum, eosinophil counts in peripheral blood, prevalence of asthma, and nasal polyp score at baseline. Both treatments were effective in reducing the patient's symptoms by SNOT-22 at 3 months postoperatively. However, patients with adjuvant Dupi therapy exhibited significantly better endoscopic scores than those with surgery only (p = .022). Conclusion: Surgery plays an important role in treating patients with CRSwNP, and adjuvant Dupi use may facilitate objective mucosal recovery postoperatively. Level of Evidence: 4.
