Endoscopic Extended Sinus Surgery for Patients with Severe Chronic Rhinosinusitis with Nasal Polyps, the Choice of Mucoplasty: A Systematic Review.

PURPOSE OF REVIEW: The advances in the knowledge of the molecular basis of the inflammatory response in chronic rhinosinusitis with nasal polyps (CRSwNP) have led the management of these patients towards personalized and precision medicine. Surgery has been positioned as a suitable alternative in patients who do not achieve control with appropriate medical treatment, but polypoid recurrences remain a constraint. The emergence of new surgical approaches based on patient phenotyping and the poor disease control associated with type 2 inflammatory phenotype makes it necessary to review the role of personalized and precision surgery in managing the disease. RECENT FINDINGS: Surgical approaches based on wide resection of bony sinus structures and the treatment of mucosa lining the sinonasal cavity have been analyzed and compared with other techniques and seem to offer more favorable surgical outcomes and improved quality of life (QoL), in addition to lower relapse rates. The innovations with new complementary surgical techniques, such as reboot surgery adding an extended autologous mucosal graft from the nasal floor (mucoplasty), may benefit endoscopic and QoL outcomes in the most severe CRSwNP patients with type 2 phenotype. Using bilateral endonasal mucoplasty as a complementary technique to reboot surgery is a suitable technical choice that has improved short- and medium-term QoL and endoscopic outcomes for patients with severe CRSwNP. These results are likely due to a combination of the extension of reboot and the inherent inflammatory and healing properties of mucoplasty. We propose this technique as a valuable surgical resource, although more robust clinical studies are needed to evaluate its long-term benefits comprehensively.

Omalizumab Treatment in Uncontrolled Asthma and CRSwNP Patients, with Previous Endoscopic Sinus Surgery, to Improve Quality of Life and Endoscopic Outcomes: a Two-Year Real-Life Study.

PURPOSE OF REVIEW: Despite molecular underlying advances, limited and divergent data on monoclonal antibodies (mAb) therapy in chronic rhinosinusitis with nasal polyps (CRSwNP) make further analysis necessary. The objective of this study is to evaluate the effect of omalizumab as an adjunct to endoscopic sinus surgery (ESS) on the treatment of CRSwNP under real-life conditions. RECENT FINDINGS: Since the introduction of omalizumab, as the first biologic agent for the treatment of diseases such as severe allergic asthma, different studies have demonstrated an effect of omalizumab on CRSwNP, with significant improvements in sinonasal symptoms and endoscopic scores. The high efficacy derived from mAb therapy and the need for ESS prior to mAb recommended by guidelines, has led to compare both therapeutic alternatives, finding discrepancies in their effect on quality of life (QoL) and complementary tests outcomes. Patients with moderate-to-severe asthma with clinical criteria for omalizumab indication, and coexistent CRSwNP disease, were selected for a non-randomized interventional retrospective study into four treatment subgroups. Measures were analyzed and compared between groups and over time at the baseline, 16 weeks and 1 and 2 years after treatment. Omalizumab treatment in patients with previous ESS exhibited an earlier and more pronounced improvement in QoL, symptoms scale and endoscopic findings (nasal polyp score and the bilateral modified Lund-Kennedy) as early from week 16, which improvement persisted for 2 years. A greater mean improvement of 33.4 ± 6.5 (95% CI: 20.3-46.4; p < 0.001) points in sinonasal outcome test 22 (SNOT-22) was associated with ESS at week 16, against omalizumab effect (17.8 ± 7.6 [95% CI: 2.6-33.0]; p = 0.023). At year 2, an improvement in SNOT-22 of 62.6 ± 8.9 (95% CI: 48.4-84.1; p < 0.001) points was exclusively associated with omalizumab. Clinical evidence of the effect of omalizumab added to ESS treatment is provided in this study in the short- and long-term.

Role of Nasal Surgery in Adult Obstructive Sleep Apnea: A Systematic Review.

Objective To perform a systematic review to determine if isolated nasal surgery has any impact on subjective or objective parameters in adult obstructive sleep apnea (OSA) patients. Materials and Methods From December 2022 to March 2023, we conducted a search on the PubMed, Cochrane, Scopus, and Web of Science databases. Two independent investigators performed a study selection according to the established criteria, as well as data collection, including the study design, the subjective and objective parameters addressed, the type of intervention, and the outcomes, considering the methodological quality and risk of bias. Results In total, 25 studies met the selection criteria, and they showed that there is a significant improvement in sleep quality, sleepiness, nasal resistance, and snoring after isolated nasal surgery. Still, there is no relevant modification of other polysomnographic parameters. It also reduces the required titration pressures of continuous positive airway pressure (CPAP) and increases the duration of its use. Conclusion Isolated nasal surgery is not a primary treatment for OSA. Still, it improves the subjective parameters and can lead to CPAP therapy success by enhancing its effectiveness and long-term compliance.

Effect of antihypertensive treatment on the quality of life of patients with chronic rhinosinusitis with nasal polyps.

AIM: Nasal polyposis (CRSwNP) shares type 2 inflammation biomarkers with asthma, allergy or arterial hypertension (AH), including periostin, a predictive marker of severity and post-surgical recurrence of polyposis. Antihypertensives have been shown to decrease periostin expression. We set out to evaluate the effect of antihypertensives on the quality of life of patients with CRSwNP. MATERIALS AND METHODS: Retrospective study of 43 patients with CRSwNP and ah with at least 1year of follow-up and antihypertensive treatment prescribed after the diagnosis of CRSwNP. Phenotypes were analyzed (F1: isolated CRSwNP; F2: CRSwNP with asthma and/or NERD) and aspects related to quality of life (SNOT-22), clinical severity (VAS), polypoid size (NPS), exacerbations and surgical needs after the initiation of antihypertensive treatment. RESULTS: The predominant phenotype was F1 (62.8%). The number of exacerbations was 19.2% for F1, compared to 31.3% for F2. 34.8% underwent surgery after the start of antihypertensive treatment (F1=27.9% and F2=6.97%). A significant reduction in polypoid size, SNOT22 (16.4±19.6 points), and VAS scales (p<.05) was obtained. CONCLUSIONS: polypoid size, and reduce the risk of postoperative recurrence.

Tissue-specific early and late activated lymphocytes immunophenotype in chronic rhinosinusitis with nasal polyps.

KEY POINTS: T-cell activation in patients with chronic rhinosinusitis with nasal polyps (CRSwNP) is enriched by late cytotoxic T cells. The proportion of early and intermediate activated cytotoxic T cells decreases in nasal polyps of patients with CRSwNP. Our results identify late activated cytotoxic T cells as potential biomarkers or therapeutic targets for patients with CRSwNP.

Improved quality of life in patients with chronic rhinosinusitis with nasal polyps associated with expanded types of endoscopic sinus surgery: A 2-year retrospective study.

KEY POINTS: Expanded types of functional endoscopic sinus surgery (FESS) significantly improve quality of life and reduce revision surgeries rates, supporting their early application for moderate-to-severe cases. Minimal clinically important difference may play as a crucial role in defining surgical treatment response (i.e., responder and super-responder conditions). Expanded FESS benefits patients with chronic rhinosinusitis with nasal polyps but more data are required to have a clearer understanding of its uses due to varied approaches and reported outcomes in the literature.

Long-Term Clinical Outcomes in Patients with Chronic Rhinosinusitis with Nasal Polyps Associated with Expanded Types of Endoscopic Sinus Surgery.

(1) Background: Surgical criteria for chronic rhinosinusitis with nasal polyps (CRSwNP) remain unresolved. This study addresses these discrepancies by comparing the clinical outcomes of expanded-functional endoscopic sinus surgeries (E-FESS) with more-limited FESS (L-FESS). (2) Methods: A database was analyzed retrospectively to compare surgical outcomes in CRSwNP patients who underwent E-FESS versus those subjected to L-FESS. Quality of life, endoscopic and radiological outcomes were compared at the baseline and two years after surgery. The clinical status of the responder was defined when a minimal clinically important difference of 12 points in SNOT-22 change was achieved. (3) Results: A total of 274 patients met the inclusion criteria and were analyzed; 111 underwent E-FESS and 163 were subjected to L-FESS. Both groups exhibited significant clinical improvements, although a greater magnitude of change in SNOT-22 (14.8 ± 4.8, p = 0.002) was shown after E-FESS. Higher significant improvements for endoscopic and radiological scores and lower surgical revision rates were also noted in the E-FESS group. (4) Conclusions: E-FESS provides better clinical outcomes and reduced revision surgery rates when compared to L-FESS in CRSwNP patients two years after surgery, irrespective of any comorbidity. Further randomized prospective studies are needed to comprehensively contrast these results.

Survival Analysis in Patients with Laryngeal Cancer: A Retrospective Cohort Study.

INTRODUCTION: The worldwide incidence rate of laryngeal cancer is declining. However, the 5-year survival for these patients has decreased in recent years from 66% to 63%. This may be due to changes in the treatment of the disease. The present study aimed to evaluate the survival rate of patients with LC according to the stage of the disease and the treatment applied. For this purpose, surgical versus organ preservation protocols (OPP) based on chemoradiotherapy were evaluated. METHODS: A retrospective cohort study was conducted in a tertiary hospital. The study included adult patients with a clinical diagnosis of primary LC. Patients with LC and systemic metastases and those with synchronous tumors at diagnosis were excluded. Univariate and multivariate analyses were performed to determine the association between exposure to LC treatment and the time to event (death). Overall survival (OS), cause-specific survival (CSS), and disease-free survival (DFS) were calculated. RESULTS: Patients with advanced tumors (stages III and IV) had almost three times the risk of LC death than those in the initial tumor stages (I and II) [HR CCS = 2.89 (95%CI 1.30-6.39)]; [HR OS = 2.01 (95%CI 1.35-2.98)]. Patients who underwent surgical treatment had a higher chance of survival than those who were treated according to OPP [HR = 0.62; 95%CI (0.38-1.02)] in CSS, 0.74 [95%CI (0.50-1.90)] in OS, and 0.61 [95%CI (0.40-0.91)] in DFS. DISCUSSION: OPP changed the management of patients with advanced stages of LC, establishing CRT as an alternative to surgery. Our data did not reveal clinically relevant differences in OS between patients treated with OPP and those who underwent surgery; however, we reported differences in the DFS rate after five years of follow-up in favor of the surgery-treated group of patients. CONCLUSION: Surgical treatment improves CSS and DFS at five years in patients with initial LC with respect to radiation therapy alone. Furthermore, surgical treatment associated with complementary radiation therapy offers better CSS and DFS in patients with advanced LC.

Role of Fibroblasts in Chronic Inflammatory Signalling in Chronic Rhinosinusitis with Nasal Polyps-A Systematic Review.

Chronic rhinosinusitis with nasal polyps (CRSwNP) is an inflammatory disease of the nose and paranasal sinuses characterized by the presence of nasal polyps. The symptoms produced by the presence of nasal polyps such as nasal obstruction, nasal discharge, facial pain, headache, and loss of smell cause a worsening in the quality of life of patients. The source of the nasal polyps remains unclear, although it seems to be due to a chronic inflammation process in the sinonasal mucosa. Fibroblasts, the main cells in connective tissue, are intimately involved in the inflammation processes of various diseases; to this end, we carried out a systematic review to evaluate their inflammatory role in nasal polyps. Thus, we evaluated the main cytokines produced by nasal polyp-derived fibroblasts (NPDF) to assess their involvement in the production of nasal polyps and their involvement in different inflammatory pathways. The results of the review highlight the inflammatory role of NPDF through the secretion of various cytokines involved in the T1, T2, and T3 inflammatory pathways, as well as the ability of NPDF to be stimulated by a multitude of substances. With these findings, the fibroblast is positioned as a new potential therapeutic target in the treatment of CRSwNP.

Availability of Readable Online Spanish Rhinosinusitis Outcome Measures.

BACKGROUND: Patient-reported outcome measures (PROMs) are useful instruments that give providers insight into patients' experiences with disease by quantifying the symptoms that matter most to patients. Results of these questionnaires can help guide management in chronic rhinosinusitis. However, these tools are often developed for native English speakers, which disadvantages others, who already have a language barrier to care. The aim of this study is to evaluate accessibility and readability of Spanish PROMs used to evaluate rhinosinusitis. METHODS: Three Spanish readability measures, Gilliam, Peña & Mountain; SOL; and Fernandez-Huerta were used to evaluate PROMs utilized for rhinosinusitis. PROMs with sixth-grade readability level or easier were considered to meet health literacy recommendations. RESULTS: Four Spanish PROMs utilized in assessment of rhinosinusitis were identified and evaluated. Cuestionario Español de Calidad de Vida en Rinitis (ESPRINT-15) was the most readable PROM and met readability recommendations in two of three measures. Nasal Obstruction Symptom Evaluation met suggested levels in one measure. The remainder of readability scores were more difficult than recommended. CONCLUSION: PROMs are powerful clinical tools that help patients communicate their symptoms and self-advocate. For providers to gain accurate and useful information, these measures should be written at appropriate readability levels. Most Spanish PROMs used for assessment of rhinosinusitis were above recommended readability. Development of future PROMs should ensure appropriate readability levels to provide good patient-centered care for our primarily Spanish speaking patients.

Nasal Symptoms in Asthmatic Patients under Treatment with Anti-IL-5 Monoclonal Antibodies. A Real-Life Cohort Study.

Currently, some monoclonal antibodies (mAbs) are being studied for chronic rhinosinusitis with nasal polyps (CRSwNP). Three anti-IL-5 mAb: mepolizumab, reslizumab and benralizumab, have been tested through randomized clinical trials. In this real-life study, we aimed to describe the nasal effects of a cohort of asthmatic adults treated with anti-IL-5 mAb. Methods: We carried out an observational study in adults (≥18 years) on anti-IL-5 mAb treatment. Variables included ACT and SNOT−22 questionnaires, nasal polyps score, blood total IgE levels and blood eosinophil count. Results: Overall, 38 participants were included in the study; 19 patients received mepolizumab, 17 were treated with benralizumab and 2 patients were given reslizumab. There was a statistically significant difference in the ACT and SNOT−22 scores before and after mAb treatment. ACT score increased from 11.05 to 21.5 after treatment (p < 0.001). SNOT−22 decreased from 57 to 37.3 after treatment (p = 0.004). No statistically significant differences between mAb groups were observed regarding the ACT or the SNOT−22 (p = 0.775) response (p = 0.775). In addition, 60.53% of patients obtained a minimal clinically important difference (MCID) in SNOT−22. Conclusions: A significant clinical response based on SNOT−22 score evolution after anti-IL-5 mAb treatment was observed. This study also demonstrated that blood eosinophil count, rather than serum total IgE levels, is the best predictor of asthma symptom improvement, which was assessed through the ACT and SNOT−22 questionnaires.

Analysis of Prevalence and Predictive Factors of Long-Lasting Olfactory and Gustatory Dysfunction in COVID-19 Patients.

BACKGROUND: Although smell and taste disorders are highly prevalent symptoms of COVID-19 infection, the predictive factors leading to long-lasting chemosensory dysfunction are still poorly understood. METHODS: 102 out of 421 (24.2%) mildly symptomatic COVID-19 patients completed a second questionnaire about the evolution of their symptoms one year after the infection using visual analog scales (VAS). A subgroup of 69 patients also underwent psychophysical evaluation of olfactory function through UPSIT. RESULTS: The prevalence of chemosensory dysfunction decreased from 82.4% to 45.1% after 12 months, with 46.1% of patients reporting a complete recovery. Patients older than 40 years (OR = 0.20; 95% CI: [0.07, 0.56]) and with a duration of loss of smell longer than four weeks saw a lower odds ratio for recovery (OR = 0.27; 95% CI: [0.10, 0.76]). In addition, 28 patients (35.9%) reported suffering from parosmia, which was associated with moderate to severe taste dysfunction at the baseline (OR = 7.80; 95% CI: [1.70, 35.8]). Among the 69 subjects who underwent the UPSIT, 57 (82.6%) presented some degree of smell dysfunction, showing a moderate correlation with self-reported VAS (r = -0.36, p = 0.0027). CONCLUSION: A clinically relevant number of subjects reported persistent chemosensory dysfunction and parosmia one year after COVID-19 infection, with a moderate correlation with psychophysical olfactory tests.

Usefulness of endonasal flaps and grafts in skull base surgery. Consensus document.

INTRODUCTION: Skull base reconstruction is one of the greatest challenges extended endonasal endoscopic surgery. Many grafts and flaps from the endonasal fossa have been demonstrated to be useful in the control of complications such a cerebrospinal fluid leaks. Review and analysis of these resources are necessary in skull base recontruction to improve outcomes. OBJECTIVES: The target is to create a consensus document on the use of different endonasal flaps and grafts in the skull base surgery. MATERIAL AND METHODS: Literature review of the most relevant free grafts and vascularized flaps from the endonasal fossa. Analysis using the Delphi method on the use of the different endonasal resources for endoscopic repair of skull base defects. RESULTS: We obtained two results: 1) A selection of the most representative flaps and grafts from the endonasal fossa, describing origin, surface and indications, based on a literature review. 2) A consensus document, using Delphi methodology, with general considerations (2), recommendations (10) and limitations (6) of the different endonasal flaps and grafts. CONCLUSIONS: We present the first consensus document in the field of extended endonasal endoscopic surgery using the Delphi method as a working tool. We highlight the usefulness of the nasoseptal flap together with other endonasal flaps and grafts for skull base reconstruction.

Usefulness of endonasal mucoplasty in the surgical treatment of chronic rhinosinusitis with nasal polyps. Prospective study.

Chronic Rhinosinusitis with Nasal Polyps (CRScPN) is a disease with great impact on health. The surgical option using endoscopic nasosinus surgery is the therapeutic alternative when control of the disease is not achieved with medical treatment. Extensive endoscopic approaches are being postulated as a possible best surgical treatment option in certain phenotypes of CRScPN. Endonasal mucoplasty associated with these approaches has been shown to be a complementary technique that improves both healing and mucosal oedema in patients with CRScPN in the short term. The aim of our study was to analyse the results of endonasal mucoplasty associated with a complete ethmoid-sphenoidotomy plus grade III frontal sinusotomy in the treatment of CRScPN in the medium term. For this purpose, a prospective case-control study (10/10) was carried out on patients with CRScPN. In the case group, endonasal mucoplasty in the left nostril was associated with surgery, and the control group was not. The assessment of quality of life at one year after surgery, as measured by the mean difference in SNOT-22 (mean [SD]), in the case group was significantly better than in the control group, (45.9 [19.6]-26.6 [16.05], P = 0.027). The endoscopic improvement in healing and mucosal oedema, measured by the Modified Lund-Kennedy scale, showed relevant improvements, when comparing both pits, but without reaching significance (P = 0.29). Endonasal mucoplasty promotes short-term healing, improving the quality of life in the medium term (one year) of patients treated with extensive endoscopic breast resections.

Loss of Smell and Taste Can Accurately Predict COVID-19 Infection: A Machine-Learning Approach.

The COVID-19 outbreak has spread extensively around the world. Loss of smell and taste have emerged as main predictors for COVID-19. The objective of our study is to develop a comprehensive machine learning (ML) modelling framework to assess the predictive value of smell and taste disorders, along with other symptoms, in COVID-19 infection. A multicenter case-control study was performed, in which suspected cases for COVID-19, who were tested by real-time reverse-transcription polymerase chain reaction (RT-PCR), informed about the presence and severity of their symptoms using visual analog scales (VAS). ML algorithms were applied to the collected data to predict a COVID-19 diagnosis using a 50-fold cross-validation scheme by randomly splitting the patients in training (75%) and testing datasets (25%). A total of 777 patients were included. Loss of smell and taste were found to be the symptoms with higher odds ratios of 6.21 and 2.42 for COVID-19 positivity. The ML algorithms applied reached an average accuracy of 80%, a sensitivity of 82%, and a specificity of 78% when using VAS to predict a COVID-19 diagnosis. This study concludes that smell and taste disorders are accurate predictors, with ML algorithms constituting helpful tools for COVID-19 diagnostic prediction.

Radioanatomical study of the extended free nasal floor mucosal graft and its clinical applications.

OBJECTIVES: To perform a radio-anatomical evaluation of the nasal cavity floor free mucosal graft (endonasal extended mucoplasty, EEM) to repair mucosal defects after an extended ethmoid-sphenoidotomy. METHODS: A human cadaveric study (radiological and anatomical dissection) and an in vivo study in surgical patients with CRSwNP were performed. The EEM areas were compared between 3D reconstruction from CT scans and anatomical/surgical dissections, both in cadaver specimens and in patients. Feasibility was assessed by correlation between the EEM area on CT scans and when harvested in cadavers and when grafted in patients. Usefulness was assessed by the degree of coverage of the EEM in the surface exposed after an extended ethmoid-sphenoidotomy. Both feasibility and usefulness were assessed in cadaveric specimens (n = 15) and patients (n = 4). RESULTS: Fifteen cadaveric specimens and 4 patients with bilateral CRSwNP were included. The mean (SD) areas obtained in the cadaveric radiological and anatomical studies were 9.44 (2.07) cm2 and 8.03 (1.36) cm2, respectively (intraclass correlation coefficient 0.59, moderate correlation), and in 3D reconstruction for operated patients were 10.32 (0.98) cm2 and 11.27 (2.44) cm2, respectively. The coverage of the ethmoidal roof in the cadaveric dissection study was 100%, from the anterior ethmoidal artery to the posterior ethmoidal artery, covering the planun sphenoidale up to 75% in the case series. In 87.5% of the cases, up to 50% of the papiracea lamina was covered. CONCLUSION: The EEM have shown to be a feasible and useful grafting technique to repair skull base defects after performing an extended ethmoid-sphenoidotomy during surgery for CRSwNP. LEVEL OF EVIDENCE: NA.

Recommendations on the use of neuromonitoring in thyroid and parathyroid surgery. / Recomendaciones sobre el uso de la neuromonitorización en cirugía de tiroides y paratiroides.

INTRODUCTION: Thyroid and parathyroid surgery (TPTS) is associated with risk of injury to the recurrent laryngeal nerve, superior laryngeal nerve and voice changes. Intraoperative neuromonitoring (IONM), intermittent or continuous, evaluates the functional state of the laryngeal nerves and is being increasingly used. This means that points of consensus on the most controversial aspects are necessary. OBJECTIVE: To develop a support document for guidance on the use of IONM in TPTS. METHOD: Work group consensus through systematic review and the Delphi method. RESULTS: Seven sections were identified on which points of consensus were identified: indications, equipment, technique (programming and registration parameters), behaviour on loss of signal, laryngoscopy, voice and legal implications. CONCLUSIONS: IONM helps in the location and identification of the recurrent laryngeal nerve, helps during its dissection, reports on its functional status at the end of surgery and enables decision-making in the event of loss of signal in the first operated side in a scheduled bilateral thyroidectomy or previous contralateral paralysis. The accuracy of IONM depends on variables such as accomplished technique, technology and training in the correct execution of the technique and interpretation of the signal. This document is a starting point for future agreements on TPTS in each of the sections of consensus.

[Treatment of peripharyngeal abscesses by means of intra-oral puncture-aspiration and drainage]. / Tratamiento de los abscesos perifaríngeos mediante punción-aspiración y drenaje por vía intraoral.

INTRODUCTION: Parapharyngeal and retropharyngeal abscesses are life-threatening infections, with a much lower incidence since the advent of antibiotics. However, they still represent a considerable number of emergency visits to reference centres where they are managed with various protocols to improve both morbidity and mortality. PATIENTS AND METHOD: Medical records of 25 consecutive patients at our institution (17 adults and 8 children) diagnosed and treated with the same protocol for peripharyngeal abscess were retrospectively reviewed. RESULTS: All cases were managed using a minimally-invasive intra-oral approach, with resolution of the clinical findings and symptoms. CONCLUSIONS: Puncture with intra-oral aspiration and/or drainage of peripharyngeal abscesses is an effective option instead of the external approach.
