Real-world effectiveness of dupilumab in a European cohort of CRSwNP (CHRINOSOR)

BackgroundPivotal studies with dupilumab demonstrated clinically relevant improvements in nasal polyp score (NPS), symptom and quality of life scores in patients with chronic rhinosinusitis with nasal polyps (CRSwNP). ObjectiveWe evaluated the effectiveness of dupilumab in a large-scale CRSwNP cohort from 6 European tertiary care centres. MethodologyNPS, SinoNasal Outcome Test (SNOT)-22 score, visual analogue scale (VAS) for total sinus symptoms, loss of smell (LoS) and nasal blockage (NB), and Asthma Control Test (ACT) score were collected from hospital records and assessed at baseline, 24 and 52 weeks of treatment of dupilumab in CRSwNP patients. Treatment effectiveness was evaluated in relation to demographic and lifestyle factors, sinus surgery history, presence of comorbidities and blood eosinophil counts (BEC). Treatment response was evaluated according to EUFOREA 2021 criteria. ResultsAll patient outcomes improved at 24 and 52 weeks of treatment compared to baseline. Dupilumab showed effectiveness independent of age, sex, body mass index, smoking status, prior sinus surgery, presence of asthma, NSAID exacerbated respiratory disease (NERD), allergy or baseline BEC. 92.5% and 94.4% showed an improvement in at least 1 EUFOREA criterion at 24 and 52 weeks respectively. 54.4% and 68.2% reached all 4 of the more stringent EUFOREA criteria at 24 and 52 weeks respectively. ConclusionsReal-world evaluation of dupilumab effectiveness demonstrates a robust and sustained response in at least two thirds of patients at 52 weeks of treatment. Favourable treatment response was independent of the number of sinus surgery procedures, major comorbidities or baseline systemic levels of type 2 inflammation.

Comparison of Effectiveness of Conventional Polypectomy with Functional Endoscopic Sinus Surgery

It is common for rhinologists to face nasal polyposis. When other treatments have failed, patients must undergo Functional Endoscopic Sinus Surgery (FESS) with a microdebrider or traditional equipment to clear out their sinuses and restore normal airflow. Objective: To compare the effectiveness of conventional polypectomy with functional endoscopic sinus surgery in patients presenting to tertiary level care hospital in Islamabad, Pakistan. Methods: This study was conducted at Department of ENT Head and Neck Surgery, Pakistan Institute of Medical Sciences, Islamabad from November 2017 to December 2018. Eighty-eight patients were enrolled and they were randomly into group A and group B assigned for conventional polypectomy and functional endoscopic sinus surgery, respectively. Results: There were 27 (61.4%) males and 17 (38.6%) females and mean age was 34.59 ± 12.00 years in conventional polypectomy and 28 (63.6%) males and 16 (36.5%) females and mean age was 36.64 ± 10.76 years in function endoscopic sinus surgery. The recurrence rate after 6 months in patients underwent conventional polypectomy was 18 (40.9%) and functional endoscopic sinus surgery was 2 (4.5%). Conclusion: The frequency of recurrence of nasal polyps after conventional polypectomy was more than in patients receiving functional endoscopic sinus surgery procedure.

Efficacy and safety of middle turbinate surgery: a systematic review.

Middle turbinate (MT) surgery is extremely common during endoscopic sinus surgery procedures, though no agreement exists on which techniques provide the best outcomes. This PRISMA-compliant systematic review aims to assess which MT surgery technique yields the least postoperative adverse effects and the best objective and subjective outcomes. A comprehensive search criteria was conducted in multiple databases up to July 3, 2023, to identify studies reporting surgical treatments of the MT. After screening and quality assessment, 14 articles were included for analysis. Data on patients demographics, surgical approaches, postoperative treatment and follow-up, objective and subjective outcomes were extracted and reviewed. Out of 173 unique papers identified, 14 articles met the inclusion criteria, predominantly randomized controlled trials (n = 9). Antero-inferior middle turbinectomy was the predominant surgical approach. Most studies evaluated results with postoperative endoscopy, a superior outcome was documented in the intervention group (ten out of eleven cases). In four out five studies using the SNOT-22, the treatment group was associated with a statistically significant improvement. Olfactory questionnaires highlighted superior olfactory outcome in two out of three studies. The UPSIT score revealed no significant difference between groups. Objective olfactory assessments favored treatment groups in both studies utilizing olfactometry. It seems that a partial MT surgical approach consistently yields subjective and objective improvements compared to conservative measures, also suggesting a positive impact on smell function. Despite it appears that better outcomes with fewer complications are consistently achieved with partial techniques, it remains challenging identifying which partial technique surpasses the others, due to significant heterogeneity among the studies.

Exploring the Ovine Anatomy: A Comprehensive Study of the Sheep's Head for Basic Training in Functional Endoscopic Sinus Surgery.

Training young doctors in functional endoscopic sinus surgery requires dedicated centers for cadaveric dissections. However, ethical constraints have limited cadaver availability. Alternative anatomical models, like the ovine model, are being explored for effective training, offering easier procurement and resembling human head anatomy. This study aims to demonstrate that the ovine model is useful for endoscopic sinus surgery training, highlighting the anatomical, imaging, histological, and endoscopic aspects. Three adult Native Romanian Turcana sheep's heads were obtained fresh and frozen from a local slaughterhouse. Using a helical scanner, CT scans were performed, and anatomical structures in the images were carefully labeled. Two heads frozen at -20°C were serially sectioned, with one cut sagittally, dividing the skull, and the other head sectioned transversely with 2.5 cm thickness. Sectional photographs were taken. The third sheep's head underwent endoscopy, and samples from the septal mucosa and inferior turbinate were collected for histopathology examination. The specimens were processed, stained, and examined by a pathologist. The study successfully highlighted the gross anatomy, CT imaging aspects, histological characteristics of sheep nasal mucosa, and endoscopic features, demonstrating the similarity of the sheep's head to human anatomy, making it a suitable anatomical training model for endoscopic sinus surgery. The use of sheep's heads as substitutes for human cadaver heads in nasal surgery simulations presents a promising avenue for research. The anatomical similarities and cost-effectiveness make sheep's heads a practical choice for certain aspects of nasal surgery investigation. However, researchers must approach this methodology with a thorough understanding of its limitations, including anatomical and biomechanical differences. Validation studies comparing outcomes with human models are crucial to establishing reliability. The sheep's head anatomical model provides a highly valuable experience for young trainees in endoscopic sinus surgery. Despite encountering several challenges, including some anatomical differences, considering its advantageous attributes renders it an ideal material for mimicking surgical procedures in functional endoscopic sinus surgery.

Definition of severity and treatment response in chronic rhinosinusitis with nasal polyps: a Delphi study among French experts

ABSTRACT Introduction The introduction of biotherapies has significantly changed the management of patients with chronic rhinosinusitis with nasal polyps (CRSwNP). These drugs are generally reserved for severe or recurrent CRSwNP. Thus, the concepts of severity of the disease and treatment response must be mastered by otorhinolaryngologists. However, a clear definition of these concepts in CRSwNP is missing. Methods This article focuses on definitions of severity and treatment response in CRSwNP by providing an expert consensus among French rhinologists, using a Delphi study. Results The severity assessment should seek the presence of uncontrolled asthma, olfactory disorders, nasal blockage, impaired quality of life (QOL) and cumulative annual dose of systemic corticosteroids. The treatment response should assess the presence of olfactory disorders, nasal blockage, QOL impairment, response to background therapy, resistance and/or dependence to oral corticosteroids, cumulative annual dose of systemic corticosteroids, response to surgery and to biologics. A failure after polypectomy should not be considered as a failure of surgical management of CRSwNP and must discuss the realization of an extended sinus surgery procedure before the prescription of biologics. Conclusion Definitions of severity, control of CRSwNP, as well as therapeutic strategies to improve patients’ QOL achieved high level of consensus.

The Effect of the Method of Airway Management During Endoscopic Sinus Surgery Procedures on the Intraoperative Bleeding

The objective: to conduct a comparative assessment of the severity of intraoperative bleeding with different methods of airway management (using a laryngeal mask and endotracheal tube) during endoscopic rhinosinussurgical procedures.Subjects and Methods. A prospective randomized cohort single-center study of 160 cases of endoscopic rhinosinussurgical procedures under general anesthesia was conducted.Tracheal intubation (TI) was used in 79 cases (Group 1), a laryngeal mask (LM) – in 81 (Group 2). The evaluation criteria in the groups included the bleeding intensity (BI) by 6-point scale of average categories (Fromme-Boezaart Score), indicators characterizing the state of blood circulation during surgery: HR, BPsys., BPdiast., MAP, and perfusion index.Results. Significantly lower BI values were observed in Group 2 at all time points of the study (at the 10th, 30th and 60th minute of surgery). This was due both to using a laryngeal mask, and to lower HR, BPsys., BPdiast, and MAP.Conclusion. The use of a laryngeal mask for airway management during general anesthesia in endoscopic rhinosinussurgical procedures helps to reduce the intensity of surgical field bleeding.

Temporal and Permanent Changes Induced by Maxillary Sinus Lifting with Bone Grafts and Maxillary Functional Endoscopic Sinus Surgery in the Voice Characteristics-Systematic Review.

Sinus surgery procedures such as sinus lifting with bone grafting or maxillary functional endoscopy surgery (FESS) can present different complications. The aims of this systematic review are to compile the post-operatory complications of sinus elevation with bone grafting and FESS including voice changes, and to elucidate if those changes are either permanent or temporary. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) were used, and the literature was exhaustively searched without time restrictions for randomized and non-randomized clinical studies, cohort studies (prospective and retrospective), and clinical case reports with ≥4 cases focused on sinus lift procedures with bone grafts and functional endoscopic maxillary sinus surgery. A total of 435 manuscripts were identified. After reading the abstracts, 101 articles were selected to be read in full. Twenty articles that fulfilled the inclusion criteria were included for analysis. Within the limitations of this systematic review, complications are frequent after sinus lifting with bone grafts and after FEES. Voice parameters are scarcely evaluated after sinus lifting with bone grafts and no voice changes are reported. The voice changes that occur after FESS include a decreased fundamental frequency, increased nasality, and nasalance, all of which are transitory.

Functional endoscopic sinus surgery outcome in chronic rhinosinusitis patients with hypoplastic maxillary sinus.

To review the clinical characteristics, prevalence and outcomes of chronic rhinosinusitis patients with a hypoplastic maxillary sinus who underwent functional endoscopic sinus surgery. A retrospective review was performed for the 814 consecutive, elective functional endoscopic sinus surgery procedures performed at an academic centre from 2010 to 2020, to identify patients with a hypoplastic maxillary sinus. A total of 56 hypoplastic maxillary sinus cases were detected. Maxillary sinus hypoplasia presented unilaterally in 20 cases and bilaterally in 18 cases. Of the maxillary sinus hypoplasia cases, 38 were type I, 17 were type II and 1 was type III. The average Lund-McKay score was 8.6. No major post-operative complications were reported. Four patients had minor complications and one had persistent post-nasal drip. Functional endoscopic sinus surgery is a safe and effective procedure for improving the clinical condition of patients with a hypoplastic maxillary sinus; however, careful pre-operative radiological evaluation, identification of intra-operative endoscopic landmarks and use of additional techniques may be essential to achieve satisfactory results and avoid possible serious complications.

Hydraulic dissection technique during endoscopic sinus surgery using a novel balloon sinus dilation device.

BackgroundMore than a decade after its introduction, some rhinologic surgeons have incorporated the technique of balloon sinus dilation (BSD) technology into “hybrid” endoscopic sinus surgery (ESS) procedures. A novel BSD device which can be placed over standard surgical instruments, including surgical navigation instruments, has recently been introduced. We present a case series in which this device was used as a hydraulic dissection tool to aid safe efficient surgery in difficult‐to‐access locations of the paranasal sinuses during hybrid ESS procedures.ObjectiveHighlight the potential role of hydraulic dissection techniques during ESS utilizing BSD. MethodsRetrospective case series of patients who underwent ESS performed in part with a novel BSD device.ResultsA total of 10 patients who underwent hybrid ESS with BSD were reviewed. In all 10 cases, the novel BSD device was used without complication. The device was used over straight and curved suctions while being tracked with surgical navigation in all cases. Thirteen posterior ethmoid dissections, 12 sphenoidotomies, and 8 frontal sinusotomies were assisted with the device. For the selected dissections in which the balloon was utilized, the operating surgeon found it to be helpful in creating more space in difficult to access areas which allowed for continued safe surgical dissection.ConclusionsSinus balloon devices can be used as a hydraulic dissection tool and may be a useful adjunct during ESS. The novel dilation system used in this study, which deploys a sinus balloon device over standard surgical instruments with surgical navigation, provides even more opportunity to accurately dissect difficult areas of the paranasal sinuses safely and efficiently. Further studies evaluating the exact role of sinus balloon devices used as a hydraulic dissection tool during ESS are warranted.Level of Evidence4.

Trends in Endoscopic Sinonasal Debridement in the Medicare Population.

Nasal/sinus endoscopy with biopsy/polypectomy/debridement, or Current Procedure Terminology code 31237, is one of the top 10 most frequent and highest billed otolaryngology procedures among Medicare patients. We analyzed temporal and geographic trends in endoscopic debridement, and correlated them with sinus surgery and balloon sinuplasty trends. Medicare Part-B National Summary Data Files were analyzed from 2000 to 2016 for temporal trends of endoscopic debridement. Medicare Physician and Other Supplier Public Use Files detailing provider information were collected and analyzed from 2012 to 2016. Individual providers performing a reportable number of procedures were included. Linear regression was used to correlate endoscopic debridement, sinus surgery, and balloon sinuplasty procedures. Between 2000 and 2016, the number of endoscopic debridement procedures increased from 31,579 to 79,762 (6.0% average annual growth). The annual total payments increased from $5,944,582 to $19,438,956 (8.4% average annual growth), with average allowed charge per procedure increasing from $188.24 to $243.71. The greatest and least number of debridement procedures occurred in the Southeast (12,703) and New England (1810) regions, respectively. There was a positive correlation between providers (n = 752) performing endoscopic debridement and sinus surgery (r = 0.31, p < 0.001), which was similar to providers performing endoscopic debridement and balloon sinuplasty (r = 0.29, P < 0.001). Otolaryngologists continue to perform increasing numbers of endoscopic debridements and receive increasing payments. There is some geographic variation in these trends. Among individual providers, there was a positive correlation between the number of endoscopic debridement procedures and both the number of balloon sinuplasty and sinus surgery procedures.

The Utility of Preoperative Phone Calls for Endoscopic Sinus Surgery Procedures.

Perioperative patient education improves patient satisfaction, surgical outcomes, and can reduce postoperative call volume. Here, we investigate whether the use of standardized preoperative phone calls elicits similar results in patients undergoing endoscopic sinus surgery (ESS). Patients undergoing ESS at a tertiary rhinology center were identified prospectively through the electronic medical record (EMR). In the intervention cohort, a standardized preoperative educational phone call was performed. A postoperative survey was utilized to collect self-assessment of satisfaction and understanding in all patients. Postoperative call rates were obtained from the EMR. Wilcoxon rank sum and chi-squared analyses were conducted to compare results. Demographics of the otology and rhinology cohorts were compared with a Mann Whitney U-test. Data from 43 cases and 58 controls were collected. Patients receiving the intervention were similar to controls with regard to patient-reported understanding (case:9.1 ± 1.1 vs control:9.0 ± 1.4, p = 0.801) and satisfaction (case:9.4 ± 1.1 vs 8.9 ± 1.4, p = 0.155). Both cases and controls called the clinic regarding surgical outcomes more often than for postoperative medications or administrative concerns. Independent of receiving the intervention, patients that did not call clinic postoperatively had significantly better understanding of their procedures (call:8.6 ± 1.6 vs no-call:9.5 ± 1.0, p < 0.015) and satisfaction with their experience (call:8.8 ± 1.4 vs no-call:9.5 ± 1.1, p < 0.028). Patient age may contribute to lack of impact in the rhinology cohort, as compared to the otology group, but socioeconomic status does not seem to differentiate the two samples. Though shown in other settings, a significant impact of educational phone calls prior to surgery was not observed in this sample. Patient education calls prior to endoscopic sinus surgery were not associated with changes in postoperative call volume to the clinic. Patient understanding and satisfaction may be related to other factors, such as patient selection or demographics. Future studies may target such patients prior to ESS.

A Cross-sectional Study on Chronic Fungal Rhinosinusitis in a Tertiary Care Hospital in Central Delhi, India

Chronic Rhinosinusitis is a common disorder, and its prevalence vary from 1-20% globally. The incidence of fungal sinusitis has increased to such extent in recent years that fungal infection is a common diagnosis in patients with Chronic Rhinosinusitis. The objectives of this current research were objectives of estimating the prevalence of Fungal aetiology in chronic sinusitis patients and their drug sensitivity pattern with common antifungal drugs. A total of 61 Cases present with Chronic Rhinosinusitis (CRS), visited in a tertiary care hospital based in Central Delhi, were included in our study. Excision of sinus tissue, including polyps and masses, were collected in the operation theatre during Functional Endoscopic Sinus Surgery (FESS) procedure in a sterile manner. All the tissues brought in sterile normal saline were processed for bacteriological and mycological examination. Tissues, obtained in 10% formalin were processed for histopathological and cytological analysis. A total of 14 (22.9%) cases of Chronic Rhinosinusitis were affected by fungal etiologies. By E test, the MIC range for isolates of Rhizopus arrhizus after 24 hr of incubation was 1-2 μg/mL, and the mean was 1.5 μg/Ml. Similarly, the MIC range for isolates of Aspergillus flavus after 48 hr of incubation was 0.5-16 μg/mL, and the mean was 4.09μg/mL. By the M38-A broth dilution method, the MIC range for the isolates of Rhizopus arrhizus after 24 hr of incubation was 0.5-2 μg/mL, and the mean was 1.25 μg/ml. Similarly, the MIC range for isolates of Aspergillus flavus after 48 hr of incubation was 0.5-4 μg/mL, and the mean was 1.95 μg/mL.

Validation of the Modena bleeding score in endoscopic sinus surgery

IntroductionThe Modena bleeding score is a categorical rating scale that allows the assessment of the surgical field in relation to bleeding during endoscopic surgery. It has recently been presented and validated in the field of endoscopic ear surgery by the present authors. The Modena bleeding score provides five grades for rating the surgical field during endoscopic procedures (from grade 1 − no bleeding to grade 5 − bleeding that prevents every surgical procedure except those dedicated to bleeding control). ObjectiveThe aim of this study was to validate the Modena bleeding score in the setting of endoscopic sinus surgery. MethodsFifteen three-minute videos of endoscopic sinus surgery procedures (each containing three bleeding situations) were evaluated by 15 specialists, using the Modena bleeding score. Intra and inter-rater reliability were assessed, and the clinical validity of the Modena bleeding score was calculated using a referent standard. ResultsThe data analysis showed an intra-rater reliability ranging from 0.6336 to 0.861. The inter-rater reliability ranged from 0.676 to 0.844. The clinical validity was α = 0.70; confidence limits: 0.64 − 0.75, corresponding to substantial agreement. ConclusionThe Modena bleeding score is an effective method to score bleeding during endoscopic sinus surgery. Its application in future research could facilitate the performance and efficacy assessment of surgical techniques, materials or devices aimed to bleeding control during endoscopic sinus surgery.

Quality of Life Outcomes in Frontal Sinus Surgery.

Introduction: Although significant experience has been gained in the technical nuances of endoscopic sinus surgery procedures, the patient-reported outcomes of frontal endoscopic sinus surgery procedures are still poorly understood. In this study we used the validated patient outcome measure Sino Nasal Outcome Test-22 (SNOT-22) to assess the preoperative and postoperative quality of life in patients undergoing extended endoscopic frontal sinus surgery (Draf type 2 and Draf type 3 procedures). Methods: Out of a total of 680 patients undergoing endoscopic sinus and skull base surgery and 186 patients undergoing frontal sinus surgery, 99 chronic rhinosinusitis patients with (CRSwNP) or without (CRSnNP) nasal polyps undergoing Draf 2 or Draf 3 were assessed. Results: The mean preoperative SNOT-22 was 45.6 points for patients undergoing Draf 2 and 59 for patients undergoing Draf 3, while the mean radiological Lund–Mackay Score was 14.3 and 14.5, respectively. Mean SNOT 22 improvement was 22.9 points for Draf 2 and 37 points for Draf 3 respectively and remained significant in all time intervals, including at 4 years after surgery. With the exception of loss of smell/taste, all symptoms improved by a far bigger extent in Draf 3 group, despite the considerably worse starting point. Effect size (Cohen / Standard Deviations) of Draf 3 was greatest in the following symptoms: “being frustrated/restless/irritable” (1.63), “nasal blockage” (1.43), “reduced concentration” (1.35), “fatigue” (1.29) “runny nose” (1.26) and “need to blow nose” (1.17). Frontal sinus (neo) ostium was patent (fully or partly) at last follow up in 98% of Draf 2 patients and in 88% of patients following Draf 3. Patients with non-patent frontal (neo-) ostium however had a mean postoperative SNOT 22 score of 43 compared to 20 of those with patent frontal sinus (neo-) ostium, although the difference was not statistically significant. Conclusion: Patients undergoing Draf 3 have a greater burden of disease, including both nasal and emotional/general symptoms compared to Draf 2 patients; surgery results in improvement in both groups, although Draf 3 patients have the greatest benefit, especially in emotional / general symptons. In this way both groups achieve similar postoperative quality of life, despite the different starting points.

Evaluación radio-anatómica del receso del seno frontal en población colombiana

Objetivos: La cirugía endoscópica del seno frontal es quizá uno de los procedimientos más complejos en el manejo endoscópico de los senos paranasales debido a su localización anatómica y a las múltiples variantes anatómicas que pueden encontrarse durante su disección. Es indispensable conocer al detalle la anatomía de esta región en nuestra población para la planeación quirúrgica de los pacientes. Actualmente en nuestro país se desconoce la frecuencia de estas variaciones.

The efficacy of esmolol, remifentanil and nitroglycerin in controlled hypotension for functional endoscopic sinus surgery

IntroductionControlled hypotension is a reversible procedure in which the patient’s baseline mean arterial blood pressure is reduced by 30% and sustained at 60–70 mmHg during the procedure. It decreases blood loss and provides clear surgical field during the procedures. ObjectivesThe purpose of this study was to compare the efficacy of controlled hypotension agents esmolol, remifentanil, and nitroglycerin in functional endoscopic sinus surgery, in terms of hemodynamic changes and impact on the surgical efficiency. MethodsThe research was carried out as a cohort study. Patients who underwent functional endoscopic sinus surgery were randomized into 3 groups. Controlled hypotension was achieved with remifentanil (Group R), esmolol (Group E) and nitroglycerin (Group N). The efficacy of the drugs was tested by comparing the length of time with the targeted mean arterial pressure, the amount of anesthetics used, surgical field bleeding score and surgeon’s satisfaction. ResultsBetween May to December 2015, 60 patients were included and randomized equally into 3 different study groups. The median of the length of time with the targeted mean arterial pressure was shorter in the Group R when compared with Group E (p = 0.01) and Group N (p = 0.14). The amount of volatile anesthetics used was 25.0 mL (15–51), 43.0 mL (21–105) and 40.0 mL (26–97) in Groups R, E and N, respectively (p < 0.001). While there was more bleeding with nitroglycerin, surgical field bleeding scores were lower in Group R when compared with esmolol (p = 0.001) and nitroglycerin (p < 0.001). The analysis of surgeon’s satisfaction scores concluded that surgeons were more satisfied with the group R (100%), when compared with group E (60%) and group N (30%) (p < 0.001). ConclusionLess volatile agent, short time to achieve controlled hypotension, stable blood pressure, lower surgical field bleeding scores and larger length of time with the targeted mean arterial pressure were found as the advantages of Remifentanil. Less costly, efficiency of achieving the targeted median arterial pressure and less postoperative complications were the advantages of nitroglycerin. In functional endoscopic sinus surgery procedures, appropriate controlled hypotensive agents should be selected according to the patients’ characteristics and advantages/disadvantages of the drugs.

Management strategies for recurrent acute rhinosinusitis.

BackgroundManagement of patients with recurrent acute rhinosinusitis (RARS) is often challenging, and robust data in the literature is scant. The aim of this study is to better characterize the current treatment strategies for RARS used by otolaryngologists.MethodsAn online survey sent to all members of the American Rhinologic Society in a 1 month period evaluated demographics, practice characteristics, and management strategies for patients with RARS, subdivided into those with (RARSwD) and without (RARSsD) septal deviation. Eighty‐eight practicing members responded, of whom 41% were fellowship‐trained rhinologists.ResultsFor most cases of RARSsD, 61% of otolaryngologists would primarily use medical management. Most would wait until patients had experienced 4–5 episodes to perform balloon sinuplasty (80%) or formal sinus surgery (79%). The sinus surgery procedure of choice was limited sinus surgery (62%). For RARSwD, 52% primarily chose medical management. Most would wait until patients had experienced 4–5 episodes to perform balloon sinuplasty (80%) or formal sinus surgery (78%). Nearly all fellowship‐trained rhinologists (97%) would perform limited sinus surgery with septoplasty for RARSwD, compared to only 70% of other otolaryngologists who would do so and 24% who would perform complete sinus surgery with septoplasty. While 89% of practitioners in private practice would wait to perform balloon sinuplasty until patients had experienced 4–5 episodes, only 68% of those in academia would wait this long and 23% would do so after only 1–3 episodes.ConclusionsTreatment of patients with RARS is complex, and the differences in strategies employed between groups of otolaryngologists may reflect their training backgrounds and different patient populations.Level of EvidenceV

Simultaneous endoscopic endonasal sinus surgery and sinus augmentation with immediate implant placement: A retrospective clinical study of 23 patients

ObjectiveThe aim of this study was to evaluate the efficacy of simultaneous endoscopic endonasal sinus surgery and sinus augmentation with immediate implant placement. Patients and methodsThe study patients (n = 23) were partially or completely edentulous in the posterior maxilla and required maxillary sinus augmentation. All included patients had a sinus pathology confirmed clinically and radiographically. The technique of simultaneous endoscopic endonasal sinus surgery and sinus augmentation was used in 15 patients, with eight endonasal sinus surgery procedures being performed 2–3 months before sinus augmentation. Where possible, implants were placed during the same surgical procedure (with a ridge bone height of at least 4 mm). ResultsThere were no any major intraoperative complications. Implants placed in the reconstructed areas were shown to integrate normally, and postoperative occlusal function and aesthetics were favorable. Of the 95 implants placed in these 23 patients, two failed to osseointegrate. ConclusionThe method of simultaneous endoscopic endonasal sinus surgery and sinus augmentation with immediate implant placement leads to a reduction in postoperative complications, significantly shortening the rehabilitation period for patients with maxillary sinus diseases and insufficient bone tissue.

Ergonomics in endoscopic sinus surgery.

Awareness of ergonomics is growing into surgical specialties including otolaryngology. Most otolaryngologists experience occupational physical discomfort, and daily incorporation of standard ergonomic principles may alleviate some of this pain. Further demonstration of surgery-related physical discomfort has been documented based on surveys of general otolaryngologists and subspecialty rhinologists. One study utilized surface electromyography to document physical findings directly associated with the endoscopic sinus surgery procedure. However, relatively little work has been published on interventions to relieve task-related pain and body discomfort in rhinology. Surgeon fatigue and bodily injury is a surprisingly frequent occurrence and is more likely to occur in procedures that are mentally challenging, prolonged, and require the surgeon to operate in a fixed position. Endoscopic sinus and skull base surgeons appear particularly susceptible to task-related physical discomfort, and incorporation of ergonomic principles should be a priority.
