Bilateral cavernous sinus and ophthalmic vein thrombosis secondary to Trueperella pyogenes rhinosinusitis.

Ophthalmic vein thrombosis is a severe clinical entity with proptosis, eyelid swelling, orbital pain and reduction of visual acuity; its incidence is rare with 3-4 cases /million /year. Clinical manifestations result from venous congestion caused by septic (orbital cellulitis) or aseptic aetiologies (coagulopathies, trauma) and in some cases it could be associated with cavernous sinus thrombosis. In this paper, we describe a case report unique in the literature, of bilateral cavernous sinus and ophthalmic veins thrombosis due to both septic and aseptic causes characterized by unilateral sphenoid sinusitis sustained by Trueperella pyogenes infection. Trueperella pyogenes is an opportunistic animal pathogen, and its infections occur in both domestic and wild animals worldwide but are rare in humans; this is the first instance of human infection in the head and neck with an unknown hypercoagulable state.

Metastases to the parotid glands: An institutional experience.

BACKGROUND: Metastatic lesions to the salivary gland are rare and mostly affect the parotids. Metastases represent 8% of all malignant lesions of the parotid gland. Around 80% originate from squamous cell carcinomas (SCC) of the head and neck region. Fine needle aspiration (FNA) plays a crucial role in distinguishing primary salivary gland lesions from metastases. Herein we describe our series of metastases to the parotid glands. MATERIALS AND METHODS: We analysed 630 parotid gland FNAs over a decade including conventional and liquid-based cytology specimens. Ancillary techniques such as immunocytochemistry (ICC) were conducted on cell blocks. RESULTS: Eighty (12.4%) cases were malignant lesions, of which 53 (63.75%) were metastases including 24% melanoma, 22.6% SCC, 19% renal carcinomas, 7.5% breast carcinomas, 11.3% lung, 9% intestinal and 1.8% testicular, malignant solitary fibrous tumour and Merkel cell carcinoma. The 53 cases, classified according to the Milan system for salivary cytopathology, belonged to 5 Suspicious for malignancy (SFM) and 48 malignant (M) categories. Forty had a known history of primary malignancy (75.4%), while 13 were suspicious to be a metastatic localisation (24.5%), distributed as 5SFM (2SCC and 3Melanoma) and 8 M. A combination of clinical history, cytomorphology and ICC identified 100% of them. CONCLUSIONS: Fine needle aspiration plays a central role in the diagnostic workup of patients with metastatic lesions to their parotid glands, thereby defining the correct management. Diagnostic accuracy may be enhanced by applying ICC. Although melanoma and SCC are the most common histological types, several other malignancies may also metastasize to the parotid glands and should be kept into consideration.

Interventional radiotherapy (brachytherapy) for re-irradiation of recurrent head and neck malignancies: oncologic outcomes and morbidity.

Objective: Management of recurrent head and neck cancer (HNC) is challenging. One option in previously irradiated patients is re-irradiation using interventional radiotherapy (IRT), the modern form of brachytherapy. Re-irradiation using IRT can be delivered as an exclusive strategy for salvage or through a postoperative or perioperative approach after salvage surgery. The aim of the present study is to analyse a bicentric Italian series focusing on the use of IRT as a re-irradiation modality and assess the resulting evidence concerning oncologic outcomes and morbidity. Methods: This is a retrospective study performed in two referral centres in Italy: Policlinico Universitario Agostino Gemelli in Rome and Azienda Ospedaliera Universitaria in Sassari. All patients who had previously received a full course of external beam RT and have been re-irradiated using high-dose-rate IRT between December 2010 and June 2023 were included. Patients were retreated either by a combination of surgery and perioperative (either endocavitary or interstitial) IRT or by exclusive interstitial IRT. Results: Thirty-four patients were included in the present series, 2 of whom underwent more than one IRT re-irradiation. Notably, no patient reported specific IRT-related toxicities. Median follow-up, excluding patients who died of HNC, was 24.5 months. Two-year local relapse-free survival was 26%, disease-specific survival 39.1%, and overall survival 36.6%. Conclusions: The present series is the largest reported experience of re-irradiation by IRT for HNC in Italy. The very low rate of toxicity confirms IRT as the safest re-irradiation modality. It is noteworthy to underline that IRT is a multidisciplinary strategy based on the close cooperation between surgeons and radiation oncologists during every phase, from the recommendation of treatment and implantation in the operating theatre, to its prescription and dose painting.

Comparative real-world outcomes of dupilumab versus endoscopic sinus surgery in the treatment of severe CRSwNP patients.

INTRODUCTION: Management of severe chronic rhinosinusitis with nasal polyps (CRSwNP) has changed significantly in recent years, with different treatments now available including biologics and endoscopic sinus surgery (ESS), although there are still few comparative studies. We aimed to compare 1-year outcomes of patients with severe CRSwNP treated with dupilumab or ESS plus intranasal corticosteroids (INCS). METHODS: In this retrospective, real-life, observational, cohort study, we enrolled 101 patients with severe CRSwNP who were treated with INCS and either ESS (n = 49) or dupilumab (n = 52). The following outcomes were considered: nasal polyp score (NPS), Sino Nasal Outcome Test-22 (SNOT-22), visual analogue scale (VAS) for specific symptoms, Sniffin' Sticks identification test (SSIT), need for oral corticosteroids (OCS) and local eosinophilia detected by nasal cytology. RESULTS: ΔNPS was significantly higher in the surgery group up to 12 months when the difference with dupilumab group was no longer significant (ΔNPS: 4 vs. 4.1). ΔVAS rhinorrhoea, ΔVAS smell and ΔSNOT-22 were significantly higher in the dupilumab group at 12 months (p < .05). SSIT scores were significantly better in the dupilumab group starting from the first month of follow-up (p < .05). In the dupilumab group, only 6.1% of patients had detectable local eosinophilia compared to 57% in the surgery group alongside with a lower need for OCS (16.3% vs. 61%). CONCLUSIONS: Both dupilumab and ESS were effective in improving outcomes in patients with severe CRSwNP over 12 months. Nevertheless, patients treated with dupilumab had greater improvement in terms of SNOT-22, VAS rhinorrhoea, VAS smell and SSIT scores, with better control of local inflammation and less need for OCS.

"Lombard Effect" and Voice Changes in Adductor Laryngeal Dystonia: A Pilot Study.

OBJECTIVES: The aim was to describe the acoustic, auditory-perceptive, and subjective voice changes under the Lombard effect (LE) in adductor laryngeal dystonia (AdLD) patients. METHODS: Subjective perception of vocal effort (OMNI Vocal Effort Scale OMNI-VES), Maximum Phonation Time (MPT), and the perceptual severity of dysphonia (GRBAS scale) were assessed in condition of stillness and under LE in 10 AdLD patients and in 10 patients with typical voice. Speakers were asked to produce the sustained vowel /a/ and to read a phonetically balanced text aloud. Using the PRAAT software, the following acoustic parameters were analyzed: Mean Pitch (Hz), Minimum and Maximum Intensity (dB), the Fraction of Locally Unvoiced Frames, the Number of Voice Breaks, the Degree of Voice Breaks (%), the Cepstral Peak Prominence-Smoothed (CPPS) (dB). RESULTS: Under LE, the AdLD group showed a decrease of both G and S parameters of GRBAS and subjective effort, mean MPT increased significantly; in the controls there were no significant changes. In both groups under LE, pitch and intensity of the sustained vowel /a/ significantly increased consistently with LE. In the AdLD group the mean gain of OMNI-VES score and the mean gain of each parameter of the speech analysis were significantly greater than the controls' ones. CONCLUSION: Auditory feedback deprivation obtained under LE improves subjective, perceptual-auditory, and acoustics parameters of AdLD patients. These findings encourage further research to provide new knowledge into the role of the auditory system in the pathogenesis of AdLD and to develop new therapeutic strategies.

Role of 18F-FDG PET/CT in Head and Neck Squamous Cell Carcinoma: Current Evidence and Innovative Applications.

This article provides an overview of the use of 18F-FDG PET/CT in various clinical scenarios of head-neck squamous cell carcinoma, ranging from initial staging to treatment-response assessment, and post-therapy follow-up, with a focus on the current evidence, debated issues, and innovative applications. Methodological aspects and the most frequent pitfalls in head-neck imaging interpretation are described. In the initial work-up, 18F-FDG PET/CT is recommended in patients with metastatic cervical lymphadenectomy and occult primary tumor; moreover, it is a well-established imaging tool for detecting cervical nodal involvement, distant metastases, and synchronous primary tumors. Various 18F-FDG pre-treatment parameters show prognostic value in terms of disease progression and overall survival. In this scenario, an emerging role is played by radiomics and machine learning. For radiation-treatment planning, 18F-FDG PET/CT provides an accurate delineation of target volumes and treatment adaptation. Due to its high negative predictive value, 18F-FDG PET/CT, performed at least 12 weeks after the completion of chemoradiotherapy, can prevent unnecessary neck dissections. In addition to radiomics and machine learning, emerging applications include PET/MRI, which combines the high soft-tissue contrast of MRI with the metabolic information of PET, and the use of PET radiopharmaceuticals other than 18F-FDG, which can answer specific clinical needs.

Automatic speaking valve in tracheo-esophageal speech: treatment proposal for a widespread usage.

PURPOSE: Aim of this study was to calculate the percentage of the Automatic Speaking Valve (ASV) use in a large cohort of laryngectomized patients with voice prosthesis (VP) and to analyze the main reasons for non-use. Subsequently, a specific rehabilitation training was proposed. METHODS: One hundred-ten laryngectomized patients with VP were enrolled in the first phase of the study (census). Among them, 57 patients were included in the second phase (intervention), in which a training based on moving phonatory exercises was proposed. Structured questionnaires were used before and after training in order to investigate ASV use rate (days/week and hours/day; reasons for impeding the ASV use), average adhesive life-time during ASV use; hands-free speech duration; skin irritation. Patients also expressed their degree of on a VAS scale from 0 to 100. RESULTS: In the census phase the percentage of use of ASV (everyday, without problems) was equal to 17.27% (19/110 patients). The main causes of disuse concerned excessive fatigue and poor durability of the adhesives. The analysis of the results pre vs. post-training showed a statistically significant increase (p < 0.05) in all the investigated parameters. Patients reported a good level of treatment compliance (average frequency of performing exercises equal to 4.2 ± 2.5 days/week for 1.4 ± 1.01 h/day) and high degrees of satisfaction. After treatment, the percentage of use of AVS increased by 43% reaching a rate of 60% (66/110 patients). CONCLUSION: A specific and targeted approach that simulate the phonatory and breathing difficulties of everyday life can increase the ASV usage rate.

Surgery or No Surgery? Exploring the Dilemma of Epistaxis Management in Patients with HHT.

Background: Epistaxis, particularly in Hereditary Hemorrhagic Telangiectasia (HHT) patients, is a common otolaryngological emergency, often requiring complex management. A hierarchy of increasingly invasive interventions, from external compression of the nasal pyramid to nostril closure, is typically proposed and applied. Methods: We conducted a retrospective study on HHT patients to assess the effectiveness and longevity of invasive procedures postoperatively. Data were collected using the Epistaxis Severity Score (ESS) questionnaire. The primary focus was on changes in the frequency and intensity of epistaxis, while the secondary focus was on the overall quality of life. Results: This study found that invasive procedures initially improved the frequency and intensity of epistaxis in HHT patients. However, within 1 to 9 months postoperatively, these benefits often diminished, with hemorrhagic symptoms recurring at similar or worsened levels. Conclusions: The findings suggest a need for a cautious and restrained approach to using invasive treatments in managing epistaxis in HHT patients. Highly invasive procedures should be reserved for cases where less invasive methods fail, due to their temporary effectiveness and the risk of causing anatomical-functional changes in the rhino-sinus area, complicating future management of severe epistaxis.

Management of nasal vestibule carcinomas: recommendations by the Oncological Committee of the Italian Society of Otorhinolaryngology - Head and Neck Surgery.

Objective: Squamous cell carcinoma of the nasal vestibule (NV SCC) is a head and neck malignancy for which there is no established consensus on most aspects of clinical management. The purpose of this document is to give updated recommendations that incorporate recent evidence on its clinical characteristics and the high efficacy of brachytherapy as primary treatment modality. Methods: A working group consisting of the members of the Scientific Committee for Oncology and Reconstructive Surgery of the Italian Society of Otorhinolaryngology Head and Neck Surgery and radiation oncologists expert in brachytherapy was formed to achieve a consensus. Results: Consensus was reached on a set of recommendations, proposing a refined anatomical definition of the nasal vestibule, a novel T staging system of the NV SCC, and brachytherapy as standard of care, with a new method for catheter implantation. Conclusions: The Committee emphasises the critical role of an accurate classification in clinical practice and encourages further research to validate the novel staging system and further improve treatment strategies. Where appropriate, it is recommended that patients be referred to centres with specific experience in brachytherapy for NV SCC.

p16 Expression in Laryngeal Squamous Cell Carcinoma: A Surrogate or Independent Prognostic Marker?

Laryngeal squamous cell carcinoma (LSCC) is a common malignancy that, despite scientific advancements, has not seen an improvement in its prognosis in the last decades. Few promising predictive markers have been found and none are relevant in clinical practice. p16ink4a, an oncosuppressor protein involved in cell cycle arrest, with a prognostic impact on other cancers, has been widely used in the head and neck region as a surrogate marker of HPV infection. Published papers and recent meta-analyses seem to minimize the biological role of HPV in the context of LSCC's cancerogenesis, and to disprove the reliability of p16ink4a as a surrogate prognostic marker in this context, while still highlighting its potential role as an independent predictor of survival. Unfortunately, the available literature, in particular during the last two decades, is often not focused on its potential role as an independent biomarker and few relevant data are found in papers mainly focused on HPV. The available data suggest that future research should focus specifically on p16ink4a, taking into account both its potential inactivation and overexpression, different patterns of staining, and immunohistochemistry cutoffs, and should focus not on its potential role as a surrogate marker but on its independent role as a predictor of survival.

Oxidative stress and inflammation cause auditory system damage via glial cell activation and dysregulated expression of gap junction proteins in an experimental model of styrene-induced oto/neurotoxicity.

BACKGROUND: Redox imbalance and inflammation have been proposed as the principal mechanisms of damage in the auditory system, resulting in functional alterations and hearing loss. Microglia and astrocytes play a crucial role in mediating oxidative/inflammatory injury in the central nervous system; however, the role of glial cells in the auditory damage is still elusive. OBJECTIVES: Here we investigated glial-mediated responses to toxic injury in peripheral and central structures of the auditory pathway, i.e., the cochlea and the auditory cortex (ACx), in rats exposed to styrene, a volatile compound with well-known oto/neurotoxic properties. METHODS: Male adult Wistar rats were treated with styrene (400 mg/kg daily for 3 weeks, 5/days a week). Electrophysiological, morphological, immunofluorescence and molecular analyses were performed in both the cochlea and the ACx to evaluate the mechanisms underlying styrene-induced oto/neurotoxicity in the auditory system. RESULTS: We showed that the oto/neurotoxic insult induced by styrene increases oxidative stress in both cochlea and ACx. This was associated with macrophages and glial cell activation, increased expression of inflammatory markers (i.e., pro-inflammatory cytokines and chemokine receptors) and alterations in connexin (Cxs) and pannexin (Panx) expression, likely responsible for dysregulation of the microglia/astrocyte network. Specifically, we found downregulation of Cx26 and Cx30 in the cochlea, and high level of Cx43 and Panx1 in the ACx. CONCLUSIONS: Collectively, our results provide novel evidence on the role of immune and glial cell activation in the oxidative/inflammatory damage induced by styrene in the auditory system at both peripheral and central levels, also involving alterations of gap junction networks. Our data suggest that targeting glial cells and connexin/pannexin expression might be useful to attenuate oxidative/inflammatory damage in the auditory system.

Correlation between inflammatory biomarkers and disease control in chronic rhinosinusitis with nasal polyps.

BACKGROUND: Chronic rhinosinusitis with nasal polyps (CRSwNP) may have a heterogeneous response to medical/surgical treatments based on endotypes. Data correlating biomarkers and severity of the disease are lacking. We aimed to determine if IL-5 and calprotectin may be useful in defining severity of disease and identifying uncontrolled patients. METHODS: This was a case-control study including 81 patients with diffuse CRSwNP who underwent at least one previous surgery and treated with intranasal steroids. We enrolled 39 uncontrolled patients (SNOT-22 ≥ 40 and two or more cycles of systemic corticosteroids in last year) (Group A) and 42 controlled one (SNOT-22 < 40 and less than two cycles of systemic corticosteroids in last year) (Group B). We analyzed IL-5 and calprotectin in both nasal secretions and nasal polyp tissue. RESULTS: Calprotectin and IL-5 were significantly higher in Group A in both secretions and tissue, and the higher the number of previous surgeries, the higher the levels detected in nasal secretions. At univariate analyses, smoking, asthma, non-steroidal anti-inflammatory drugs-exacerbated respiratory disease (NSAID-ERD), blood eosinophilia, neutrophils, and eosinophils at nasal cytology were significantly associated with uncontrolled disease. Multivariate analyses showed that asthma, NSAID-ERD, and IL-5 in nasal secretion/polyp tissue were significantly related to the risk of uncontrolled disease. CONCLUSIONS: Our data suggest that asthma, NSAID-ERD, and IL-5 in nasal secretions/tissue may be helpful to identify more severe patients, as they are related to the risk of uncontrolled disease. Nonetheless, high levels of calprotectin and neutrophilia were also observed in uncontrolled patients, especially after multiple surgeries.

Late Prevalence of Typical and Atypical Symptoms of Frey's Syndrome after Parotidectomy for Benign Tumor.

BACKGROUND: The treatment of choice for tumors located in the parotid gland is surgery. Nevertheless, postoperative complications are not infrequent. Regardless of the type of surgical procedure, the most common complication is Frey's syndrome (FS). Traditionally, FS includes unilateral gustatory sweating and flushing of the facial skin lining the parotid compartment. Recent research describes atypical discomfort associated with FS. The aim of this study was to assess the late prevalence and severity of both usual and atypical symptoms after parotidectomy for benign tumors. METHODS: We conducted a cross-sectional study involving 86 subjects who underwent superficial parotidectomy at least one year before the study. The questionnaire included the sweating-flushing-itch-paresthesia-pain (SFIPP) Frey scale supplemented by specific questions about symptoms. RESULTS: Sixty-seven out of eighty-six (77.9%) cases reported almost one symptom. The most frequent symptom was itch (36/67-53.7%), followed by pain (35/67-52.2%), while 28/67 (41.8%) subjects complained of atypical symptoms without flushing or sweating. A desire to treat the discomfort was reported by 50/67 (74.6%) subjects. CONCLUSIONS: Late postparotidectomy local discomfort is not infrequent and includes both usual and "unusual" symptoms almost equally. Our results suggest the importance of informing patients about the occurrence of the syndrome and the available treatment options during pre- and postoperative counseling.

Hybrid primary puncture in stapler-assisted total laryngectomy.

In Video S1, a new surgical technique for hybrid primary tracheoesophageal (TE) puncture in stapler-assisted total laryngectomy is shown. The video describes the surgical steps of the procedure and illustrates some tips and tricks. The procedure incorporates an upper mini-pharyngotomy to enable retrograde placement of the voice prosthesis (VP), eliminating the need for rigid esophagoscopy. This has made it possible to exploit, without additional risks, the potential of the stapler combined with primary TE puncture and VP placement. In our experience, this hybrid procedure in stapler-assisted total laryngectomy is not related to adverse events such as pharyngocutaneous fistula (PCF), hypertonicity, and functional complications. Therefore, it can be considered a valid technique that allows for easy insertion of a primary voice prosthesis also in case of mechanical sutures.

Temporal trends of blood eosinophilia in severe uncontrolled CRSwNP treated with dupilumab: a real-life study.

PURPOSE: Induced eosinophilia is commonly related to dupilumab treatment. We analysed the temporal trends of blood eosinophilia in patients with severe uncontrolled CRSwNP during the first year of treatment with dupilumab in real-life setting to evaluate its correlation with outcomes of response and adverse events (AEs). METHODS: Seventy-four patients with severe uncontrolled CRSwNP treated with dupilumab at our institution were enrolled. At each visit, we evaluated AEC, outcomes of response to treatment and AEs. RESULTS: A significant increase in AEC was observed since the first month with a peak at 3 months; at 12 months, the values returned comparable to those at baseline. A ≥ 50% increase of the baseline AEC with a value greater than 500 cells/mm3 was documented in 38/74 patients (Group A) regardless of the time of observation, whereas in 36/74 patients (Group B), no changes were observed. Analysing the blood eosinophilia trend over time in group A, we observed a temporary eosinophilia with early onset (within 6 months), persistent eosinophilia with early onset, and eosinophilia with late onset. No differences in terms of outcomes of response to treatment or AEs were found between Group A and Group B, or between patients who developed an AEC ≥ 1500 cells/mm3 or not. CONCLUSION: In our series, we observed that an increase in AEC with different temporal trends may be observed in CRSwNP patients during the first year of treatment with dupilumab. In our series, eosinophilia is not correlated with a negative outcome of response to treatment or a risk of AEs.

Preoperative Direct Puncture Embolization Using a Nonadhesive Ethylene Vinyl Alcohol (EVOH) Liquid Embolic Agent for Head and Neck Paragangliomas.

PURPOSE: This retrospective study aimed to assess the safety and technical efficacy of preoperative direct puncture embolization using a nonadhesive ethylene vinyl alcohol (EVOH) copolymer-based liquid embolic agent (LEA) combined with balloon occlusion at the origin of the external carotid artery for head and neck paragangliomas (HNP). METHODS: We conducted a review of all consecutive cases of HNPs treated with direct puncture embolization using EVOH-based LEAs between 2017 and 2022 in 2 tertiary high-volume hospitals. RESULTS: A total of 25 cases of HNPs in 24 patients underwent direct puncture embolization (12 males, 12 females, mean age 50.9 ± 15.6 years). The average lesion volume was 299.95 mm3. The mean procedure time was 139.11 min, and the mean volume of EVOHs used per case was 19.38 mL. Successful complete devascularization was achieved in all cases, with a homogeneous and deep penetration of the embolic agent into the tumor vessel bed regardless of the LEA type. CONCLUSION: Preoperative embolization of HNPs using a direct puncture technique and EVOHs is a safe, efficient, and feasible treatment option with a low risk of complications. This procedure facilitates surgery by transforming tumors into avascular masses that are well-delineated against the surrounding normal tissue.

Perceptual Evaluation of the Tracheoesophageal Voice: Italian Validation of the Sunderland Tracheoesophageal Perceptual Scale.

OBJECTIVES: This study aimed to validate the Sunderland Tracheoesophageal Perceptual Scale (SToPS) in the Italian language by checking the inter- and intra-rater reliability. STUDY DESIGN: Scale validation METHODS: The validation of the tool involved the following steps: (1) translation and adaptation of the SToPS into Italian language; (2) recruitment of participants (60 laryngectomized patients with a voice prosthesis and 12 health professionals-six speech and language therapists (SLTs) and six ear, nose, and throat surgeons-classified into experienced (Exp) or not at assessing voice; (3) recording of patients' speech samples; (4) perceptual evaluation of recorded speech samples (test and retest) performed by the 12 health professionals; and (5) statistical analysis (quadratic weighted Cohen kappa and weighted kappa of Light coefficients). RESULTS: When all raters were considered as one group, an agreement ≥0.50 was reached for all parameters. The "ExpSLTs" group rated more reliably than the other groups, achieving a "good" intrarater agreement for 9/10 parameters. Despite the interrater coefficients were lower than the intrarater ones for all rater groups, "ExpSLTs" obtained the best levels of interrater agreement, achieving a level of agreement ≥0.50 for all parameters. Finally, considering intrarater+interrater agreement ("good + good" or "good + moderate"), the "ExpSLTs" group showed the greatest agreement, attaining all parameters that met the criteria for "good" or "moderate" agreement levels. CONCLUSIONS: The Italian version of SToPS can be considered a reliable tool. As in the original version, expert SLTs are the better judges for tracheoesophageal voice assessment.

Chronic Rhinosinusitis with Nasal Polyps: A Survey on Routine Management and Evaluation of Disease Control in Practice.

Chronic rhinosinusitis with nasal polyps (CRSwNP) is a disease with a significant impact on quality of life. The overall goal of CRSwNP management, as with other chronic conditions, is to achieve "disease control", and for that reason, a definition of control of disease is pivotal in deciding the best treatment strategy. Although many staging systems have already been developed to evaluate the disease, disease control is not yet to be standardized, and a specific tool that is consistently applied and accepted by all practitioners is still missing in daily clinical practice. To gain an overview of the implementation and limitations of existing guidelines and to shed light on real-life definitions of control and disease severity, we conducted a nationwide survey of otorhinolaryngologists routinely treating CRSwNP to identify unmet clinical needs in Italy. The results showed homogeneous responses regarding the knowledge contained in international guidelines while highlighting the difficulty of their implementation in day-to-day practice. Respondents called attention to the importance of clinical symptoms, giving more weight to the patient's perspective. Among the symptoms to be considered, respondents emphasized nasal obstruction, followed by loss of sense of smell and rhinorrhea. Others also believe that the physician's perspective should be considered, and the inclusion of endoscopy as a measure of control was warranted by many. The need for a specific tool that is able to unequivocally ascertain disease control is increasingly pivotal in this new era of biologics for treating CRSwNP.

How to manage recurrences after surgery in CRSwNP patients in the biologic era: a narrative review.

Objective: This narrative review analyses factors affecting recurrence of Chronic rhinosinusitis with nasal polyps (CRSwNP) after surgery, such as type, extension and completeness of endoscopic sinus surgery (ESS). We also described new implications in the management of recurrences after the advent of biologics. Methods: We identified four topics: definition of disease state; factors linked to recurrence of polyps; evaluation and management of recurrence in clinical practice. Results: We analysed the differences between exacerbation and recurrence, as well as the concept of "controlled disease". We focused on potential predictors of recurrence after ESS, such as type 2 inflammation, asthma, aspirin-exacerbated respiratory disease, incomplete initial surgery and lack of adherence to long-term post-operative local corticosteroids. We discussed the new aspects of diagnosis and treatment of recurrences after surgery, summarising our suggestions in a detailed algorithm for practical management of patients with recurrent disease. Conclusions: The results emphasised the importance of accurate evaluation of patients with CRSwNP recurrence, focusing on the reasons of failure and risk of disease progression, in order to guide personalised interventions. It is crucial to define the concept of appropriate surgery, which affects the choice between starting a biologic or repeating surgery.
