RESUMO
PURPOSE: The main aim of this systematic review was to investigate the possible association between hearing loss [and/or history of otitis media with effusion (OME)] and learning difficulties in children. Secondary aims were to: (i) investigate if deaf and hard of hearing (DHH) children with learning difficulties might show different clinical and neuropsychological features compared with those with other neurodevelopmental disorders; (ii) identify possible predictors of learning difficulty in DHH children. METHODS: A review was conducted of the scientific literature reported by Pubmed, Cochrane and Scopus databases. The following inclusion criteria were used: (i) studies published after 2000; (ii) studies conducted considering subjects with age < 18 years; (iii) studies considering patients who showed both learning difficulties and hearing loss and/or episodes of OME; (iv) articles written in English. The exclusion criteria were: (i) presence in the studied cohort of any other proven comorbidities, other than hearing loss and/or OME; (ii) non-original studies. RESULTS: A total of 924 studies were identified. Four were reviewed after applying the above criteria. From their analysis it emerged that: (i) children with hearing loss who had undergone a diagnostic and rehabilitation program before 6 months of age had better levels of K readiness and language and literacy skills compared to those who had undergone it after 6 months; (ii) higher frequency of episodes of OME and the presence of a conductive hearing loss during the period of language acquisition was associated to lower scores in reading skills; (iii) reading difficulties found in subjects with hearing loss had similar characteristics to those with language difficulties. CONCLUSIONS: There is a dearth of information about this topic. Further investigations are therefore necessary on children of various ages with hearing loss to disclose learning difficulties in reading and writing abilities using current diagnostic tools.
RESUMO
Background and Objectives: Although different hypotheses have been proposed over time, there is a dearth of information on factors able to predict the response to treatment for idiopathic sudden sensorineural hearing loss (ISSNHL) and hearing recovery. The aim of this study was to apply univariate and multivariate statistical models in a retrospective clinical setting of patients given therapy for ISSNHL at our tertiary academic audiological centers to investigate the prognostic value of clinical signs, symptoms, and comorbidities in relation to hearing recovery. Materials and Methods: The inclusion criteria were: history of ISSNHL diagnosed and treated at the Padova or Modena tertiary academic audiological centers; age ≥ 18 years; availability of clinical and audiological outcome data. The exclusion criteria were: hearing loss in acoustic schwannoma, endolymphatic hydrops, meningitis, trauma (head trauma, temporal bone fracture, acoustic trauma), barotrauma, perilymphatic fistula; exposure to noise levels ≥ 80 dB in the work environment; any unilateral or bilateral hearing loss (except for presbycusis) prior to ISSNHL diagnosis; any disorders affecting the external or middle ear; any previous ear surgery; refusal to make medical data available for research purposes. Eighty-six consecutive patients (38 females, 48 males; median age: 58 years; interquartile range: 47.00-69.00 years) were included. A systemic steroid therapy was administered to all patients, either orally with prednisone or intravenously with methylprednisolone. Second-line therapy included intratympanic steroid injections and/or hyperbaric oxygen therapy. Results: A multivariate logistic regression model was used, including the non-multicollinear clinical and audiological variables, which showed a p-value < 0.10 at the univariate analyses (namely age at diagnosis, time to diagnosis, oral steroid dose, and PTA on the affected side). Only PTA on the affected side retained its statistical significance (OR: 1.0615, 95% CI: 1.0185-1.1063, p = 0.005). Conclusions: The analysis of our data showed an association between the hearing threshold before treatment and the recovery from ISSNHL. Further studies on larger cohorts (especially in a prospective setting) are needed to shed more light on the prognostic role of clinical parameters in patients with ISSNHL. In a correct counseling setting, with regard to the patient's concern about not being able to recover hearing, it is important to offer perspectives of appropriate hearing rehabilitation approaches.

OBJECTIVE: Delayed facial nerve palsy (dFNP) secondary to head injury is definitely uncommon. Although the mechanism of immediate facial nerve paralysis is well-studied, its delayed presentation remains debated. Given the dearth of available information, we reported herein our experience with 2 cases of posttraumatic dFNP. This systematic review aimed to evaluate all available information on dFNP and to assess treatment outcome also comparing conservatively and surgically approaches. DATA SOURCES: Pubmed, Scopus, and Web of Science databases were systematically screened. REVIEW METHODS: The protocol of this investigation was registered on PROSPERO in April 2023 and the systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement. RESULTS: Both patients in the case studies showed a complete recovery within 2 to 3 months after the head trauma. One of them still reported a subjective taste alteration at last control. After the application of the inclusion-exclusion criteria, 9 manuscripts with adequate relevance to this topic were included in the systematic review. The study population consisted of 1971 patients with a diagnosis of posttraumatic facial nerve palsy, of which 128 with a dFNP. CONCLUSIONS: dFNP due to head trauma is a rarely encountered clinical entity, and optimal treatment still remains to be elucidated. Based on the reported data, it seems rational to propose a conservative approach for dFNP with steroid administration as a first line in most cases, indicating surgery in severe and/or refractory cases.
RESUMO
PURPOSE: The number of cochlear implant (CI) surgeries is growing over time, with the risk of overloading CI centers in the post-surgical management. Telemedicine is a possible solution to address this phenomenon. Remote Check (RC) is an application that is specific for CI recipients monitoring. The aim of this study is to evaluate the feasibility of application, potential economic impact and patients' acceptance of RC. METHODS: The study is retrospective investigation, data on clinical, audiological features (from remote and on-site evaluation), and satisfaction surveys of 66 consecutive patients were collected; costs required for RC and for on-site evaluations were recorded as well. RESULTS: One hundred and ninety RC sessions were completed by the patients (2.88 sessions per patient). RC and on-site audiometry significantly correlated except for the 500 Hz frequency. Estimated costs for the Italian National Health System for RC review and on-site evaluations were 1.32 and 3.49 per minute, respectively. High satisfaction for RC was reached in 91 % of patients. CONCLUSION: RC revealed to be a reliable, cost-effective and well accepted tool in CI monitoring. This study preliminarily supports the hypothesis that RC could be a valid instrument to reduce CI management overload in the outpatient clinic.

Pneumo-membranous labyrinth is an almost unique condition, in which air extends into the membranous labyrinth, filling the endolymphatic sac through the vestibular aqueduct. In this manuscript, we describe and discuss a case of pneumo-membranous labyrinth, with air bubbles extending also to the endolymphatic sac, resulting in anacusis, following hyperbaric oxygen therapy for sudden sensorineural hearing loss. The patient was successfully rehabilitated with a cochlear implant, obtaining a pure-tone average of 30 dB, with a speech discrimination score of 100% at 70 dB. Laryngoscope, 134:3773-3777, 2024.

PURPOSE: In early glottic squamous cell carcinoma, similar results have been described in terms of disease control between transoral laser microsurgery (TLM) and radiation therapy (RT). During the past two decades, several studies compared subjective vocal outcomes of exclusive RT with those of TLM, showing a trend towards improving results for TLM over time. However, the objective differences in terms of spectro-acoustic voice parameters between exclusive RT and TLM have been less frequently investigated. The aim of this systematic review with meta-analysis was to evaluate voice quality after TLM and RT treatment for early glottic carcinoma, based on acoustic analysis parameters including jitter, shimmer, noise to harmonic ratio, fundamental frequency and maximum phonation time. MATERIAL AND METHODS: A search of the English published literature was conducted on the Pubmed, Scopus and Cochrane databases following PRISMA guidelines. RESULTS: A total of 441 titles were retrieved from the search. After full-text screening and application of inclusion/exclusion criteria, 12 articles were included. We found no significant differences between TLM and RT treatment in the considered acoustic analysis parameters, except for Shimmer, with more favorable values reported in the RT group. CONCLUSIONS: Considering the spread of the disease and expecting an improvement in long-term survival over time, well-designed and multicentric studies involving larger populations with a long-term follow up are mandatory to better assess objective voice outcomes in terms of spectro-acoustic voice parameters.

PURPOSE: The main aim of this study was to investigate the clinical efficacy of speech therapy, delivered via tele-practice to patients with dysphonia. A secondary aim was to verify whether a telerehabilitation-only protocol could have a clinical efficacy similar to a combined telerehabilitation and in-person approach. METHODS: Thirty-two consecutive patients undergoing telerehabilitation for dysphonia were retrospectively considered. Patients were divided into two groups: those who received combined in-person and telerehabilitation treatment, and those who underwent telerehabilitation only. RESULTS: Overall, patients included in this study showed a significant improvement in their VHI-10 scores after treatment (p < 0.001). Such an improvement was also significant in both combined therapy and telerehabilitation only groups (p = 0.019, and p = 0.002, respectively). A significant reduction in general degree of dysphonia (G), roughness (R), breathiness (B) and strain (S) scores (p < 0.001, p = 0.012, p < 0.001, and p < 0.001, respectively) was noticed over the whole sample after treatment. The same parameters showed a significant improvement also in the combined therapy group, while in the telerehabilitation only group, only G, B and S scores significantly improved. Mean phonation time, Jitter and Shimmer values significantly improved in the overall sample as well as in the combined therapy group. A significantly more favorable spectrographic class relative to the vowel /a/ was found after treatment in the whole sample, as well as in both combined therapy and telerehabilitation only groups (p < 0.001, p = 0.002, p = 0.004, respectively). CONCLUSION: This study's results seem to support telerehabilitation as a potentially effective tool to administer speech therapy in dysphonic patients, both as a single modality and in combination with traditional in-person sessions. To better characterize the clinical results of telerehabilitation in dysphonia treatment, large-scale prospective investigations are mandatory.

GJB2 mutations are the most common cause of autosomal-recessive non-syndromic sensorineural hearing loss (SNHL). The available evidence shows large phenotypic variability across different genotypes and allelic variants. The aim of this study was to investigate the clinical and audiological features of a cohort of subjects with different GJB2/GJB6 gene mutation profiles from a tertiary referral center in Northeastern Italy. We considered 57 patients with GJB2/GJB6 mutations presenting with congenital, non-syndromic SNHL, mainly coming from the Veneto region (Italy). The samples were screened for mutations in exons 1 and 2 of the GJB2 gene and for the GJB6 gene deletion del (GJB6-D13S1830). Free-field and air-conduction frequency-specific thresholds and the pure-tone average (PTA) were considered in the statistical analysis. Five patients (8.87%) had connexin gene mutations in simple heterozygosis, 15 (26.31%) in compound heterozygosis, 34 (59.64%) in homozygosis, and 3 (5.26%) with digenic patterns. The frequency-specific air-conduction thresholds showed significantly different mean values across the different genotypes (Roy's largest-root test, p = 0.0473). Despite the evidence already available on genetic SNHL, many new insights are to be expected. Further large-scale prospective studies including different populations are necessary to confirm these preliminary findings about the clinical and audiological features of patients with different GJB2/GJB6 gene mutation patterns.
RESUMO
Different inflammatory endotypes reflect the heterogeneity of chronic rhinosinusitis with nasal polyps' (CRSwNPs) clinical presentation. This retrospective study aimed to analyze the distribution of polyps in nasal cavities and paranasal sinuses to establish a possible association between CRSwNP endotypes, prognosis, and polyps' extension. This study included 449 adult patients who underwent endoscopic sinus surgery for CRSwNPs between 2009 and 2022. Patients were categorized based on the number of paranasal sinuses involved by polyps. Statistical analyses, including Cox regression, were performed to identify associations between demographic, clinical, and histopathological factors and disease recurrence. CRSwNP patients were stratified into four groups based on the extent of polyp involvement. Asthma and acetylsalicylic acid (ASA) sensitivity were associated with more sinuses involved (p-values = 0.0003 and 0.0037, respectively). Blood eosinophil counts increased with the number of sinuses affected (p-value < 0.0001). The distribution of eosinophilic and non-eosinophilic histotypes varied significantly among these groups (p-value < 0.0001). The risk of CRSwNP recurrence was higher in patients with asthma, higher basophil percentages, and eosinophilic histotype (p-value 0.0104, 0.0001, 0.0118, and 0.0104, respectively). This study suggests a positive association between the number of paranasal sinuses involved by polyps and the severity of CRSwNPs, particularly in patients with eosinophilic histotype, asthma, and ASA sensitivity.
RESUMO
BACKGROUND: Vestibular schwannoma (VS) surgery may cause facial nerve damage. However, a comprehensive evaluation of post-operative facial outcomes may be difficult to achieve. Surface electromyography (sEMG) is a promising non-invasive evaluation tool. However, its use in the follow-up after VS surgery has not been reported yet. The main objective was to develop and validate a new sEMG application specifically for the post-VS surgery setting. Secondary goals were to provide a systematic description of facial muscle activity after VS surgery and assess the association between sEMG parameters and Sunnybrook scale scores. METHODS: Thirty-three patients with facial palsy following VS surgery were included. The clinical outcomes (Sunnybrook symmetry, movement, and synkinesis scores) and sEMG parameters (signal amplitude normalized by the maximal voluntary contraction (NEMG) and sEMG synkinesis score (ESS, number of synkinesis per movement sequence)) were evaluated at the end of the follow-up. RESULTS: In all tested muscles, NEMG variance was significantly higher on the affected side than the contralateral (variance ratio test, p < 0.00001 for each muscle). In total, 30 out of 33 patients (90.9%) showed an ESS ≥ 1 (median: 2.5, IQR: 1.5-3.0). On the affected side, NEMG values positively correlated with both dynamic and overall Sunnybrook scores (Spearman's model, p < 0.05 for each muscle, except orbicularis oculi). ESS significantly correlated with the Sunnybrook synkinesis score (Spearman's rho: 0.8268, p < 0.0001). CONCLUSIONS: We described and preliminarily validated a novel multiparametric sEMG approach based on both signal amplitude and synkinesis evaluation specifically for oto-neurosurgery. Large-scale studies are mandatory to further characterize the semiological and prognostic value of facial sEMG.
RESUMO
PURPOSE: Evaluate the hearing outcomes of bilateral deaf children implanted simultaneously and define the most appropriate timing for surgery. MATERIALS AND METHODS: Audiological CI results were retrieved in both the short-term and long-term period and compared by stratifying the patients into different subcohorts according to their age at surgery. Additional data collected were age at implant activation, etiology and timing of onset of deafness, presence of psychomotor delay. RESULTS: fifty-six bilaterally implanted children were included. The short-term outcomes differed significantly when comparing groups of different ages at implantation: younger patients achieved better aided pure tone audiometry results. Considering long-term follow-up, a significant correlation was identified between an early age at implantation and the hearing outcome at ages 2 to 5 years. Perceptive levels were better at 4 years of age in the younger group. No significant differences were found between children implanted at before 12 months and between 12 and 16 months of age. CONCLUSIONS: The results of the analyzed follow-up data support the hypothesis that children implanted at before 24 months are expected to have better hearing performances. Nevertheless, these results are referred to a widely heterogeneous group of patients and the duration of auditory deprivation should be considered.

The aim of this systematic review is to shed light on the role of tumor budding (TB) in the biology, behavior, and prognosis of head and neck squamous cell carcinoma (HNSCC). A search was run in PubMed, Scopus, and Embase databases following PRISMA guidelines. After full-text screening and application of inclusion/exclusion criteria, 36 articles were included. Several investigations support the prognostic role of TB, which might play a role in selecting rational treatment strategies. To achieve this goal, further research is needed for greater standardization in TB quantification. Although TB is not included as a negative prognostic factor in the current management guidelines, it might be reasonable to consider a closer follow-up for HNSCC cases with high histopathological evidence of TB.

OBJECTIVE: The objective of this study is to assess whether cochlear implantation is feasible in patients treated with radiotherapy of the temporal bone (for diseased other than vestibular schwannoma), in terms of surgical management and auditory outcome. METHODS: A systematic review of the literature was performed, screening PubMed, Embase, and Scopus databases, according to PRISMA criteria, retrieving 12 articles. Moreover, 9 cases coming from a multicentric study involving Padova and Pisa University Hospitals, were added, for a total of 62 cases of irradiated patients receiving cochlear implantation. RESULTS: In our multicentric study we included a total of 9 patients, 6 males, and 3 females (mean age at first cochlear implantation was 53.89 years ± 21.07), while from the literature we considered 53 cases (mean age at first cochlear implantation 48.78 years ± 12.41). We considered for both groups a set of preoperative imaging abnormalities, intraoperative complications and possible postoperative complications. In our cohort, the preoperative pure tone average (PTA) in the implanted ear was 105.6 dB, and the postoperative one was 34.6 dB. In the literature the preoperative PTA was 111.5 dB (when reported), and the postoperative one 52.8 dB. CONCLUSION: Both our experience and the literature suggest that cochlear implantation in an irradiated ear is feasible with a good auditory outcome. Surgical difficulties and fitting challenges can be easily managed by professionals aware of these findings, making these patients good candidates to this rehabilitative option.

PURPOSE: Peripheral facial nerve palsy is a severely disabling condition. In current clinical practice, the commonest tools to assess facial palsy are grading scales, digital face image analyses or facial muscle electrophysiology. However, these techniques suffer from subjectivity or invasiveness and cannot be applied as part of a routine clinical assessment. Therefore, novel non-invasive office-based tools are needed. Surface electromyography (sEMG) may potentially fulfill the requirements of objectivity, low examiner-dependence, and minimal invasiveness. The aim of this systematic review is to define the state of the art on the use of sEMG for facial nerve functional assessment. MATERIALS AND METHODS: Pubmed, Scopus and Web of Science databases were systematically searched. The study protocol was registered on PROSPERO in January 2023. The review was conducted according to the PRISMA guidelines. RESULTS: After the application of inclusion-exclusion criteria, 15 manuscripts with adequate relevance to this topic were included in the review. CONCLUSIONS: Facial sEMG represents a potentially useful tool to implement objective quantification of facial nerve function in clinical practice. Given the heterogeneity of methods and analysis in the available studies, sEMG results are hardly comparable. The introduction of methodological guidelines, followed by large prospective studies on well-defined subsets of patients with facial nerve impairment, is advocated.

Importance: The tongue and oral floor represent the most involved subsite by oral cancer, and there are no reported systems to classify anteroposterior tumor extension with prognostic effect. In other cancers, the anterior vs posterior tumor extension is a relevant prognostic factor. Objective: To establish whether anterior vs posterior tumor extension may represent a prognostic factor in oral tongue and floor squamous cell carcinoma (OTFSCC). Design, Setting, and Participants: This was a retrospective cohort study of patients who underwent surgery for OTFSCC from January 1, 2010, to December 31, 2021, at 2 tertiary-level academic institutions in Italy (University of Padua and University of Brescia). Patients eligible for the study had histologically proven primary OTFSCC; underwent surgery-based, curative treatment; and had available preoperative contrast-enhanced imaging. Exposures: Four anatomical lines were designed to assess tumor extension: (1) chin-palate line (CPL), (2) chin-basion line, (3) Stensen duct line, and (4) lingual septum line. Preoperative imaging was re-evaluated, and tumor extension was classified as either anterior or posterior according to the lines. Main Outcomes and Measures: Overall survival and time to recurrence (TTR) were evaluated according to tumor extension. These outcomes were reported as 5-year survival rates with 95% CIs. Results: Of the 133 patients included, 79 (59.4%) were male, and the mean (SD) age was 62.7 (15.4) years. The 5-year TTR difference was higher for posterior vs anterior OTFSCC classified according to CPL (21.0%; 95% CI, 8.3%-33.7%), Stensen duct line (15.5%; 95% CI, 1.0%-30.0%), and lingual septum line (17.2%; 95% CI, 2.2%-32.3%). Overall survival analysis showed similar results. At the multivariable analysis on TTR, N status (adjusted hazard ratio [HR], 3.0; 95% CI, 1.2-7.1) and anteroposterior classification according to CPL (adjusted HR, 7.1; 95% CI, 0.9-54.6) were the variables associated with the highest adjusted HRs. Conclusions and Relevance: In this cohort study, OTFSCC with a posterior extension to the CPL was associated with a higher risk of recurrence and death. This analysis suggests that the poor prognosis conveyed by the posterior tumor extension is independent of other relevant prognosticators except for the burden of nodal disease. This estimate is not precise and does not allow for definitive clinically important conclusions; therefore, further prospective studies are necessary to confirm these data.

During the last decades, neuro-otological surgery has progressively reduced functional morbidity, including facial nerve damage. However, the occurrence of this sequela may significantly impact on patients' quality of life. The aim of this narrative review is to provide an update on the patho-physiological and clinical issues related to facial nerve damage in oto-neurological and skull base surgery, in the light of a comprehensive therapeutic and rehabilitative approach to iatrogenic disfunctions. The narrative review is based on a search in the PubMed, Scopus, and Web of Science databases. In this surgical setting, the onset of intraoperative facial nerve damage is related to various aspects, mainly concerning the anatomical relationship between tumor and nerve, the trajectory of the surgical corridor, and the boundaries of the resection margins. Mechanisms related to stretching, compression, devascularization, and heating may play a role in determining intraoperative facial nerve damage and provide the patho-physiological basis for possible nerve regeneration disorders. Most of the studies included in this review, dealing with the pathophysiology of surgical facial nerve injury, were preclinical. Future research should focus on the association between intraoperative trauma mechanisms and their clinical correlates in surgical practice. Further investigations should also be conducted to collect and record intraoperative data on nerve damage mechanisms, as well as the reports from neuro-monitoring systems.
RESUMO
PURPOSE: ChatGPT has gained popularity as a web application since its release in 2022. While artificial intelligence (AI) systems' potential in scientific writing is widely discussed, their reliability in reviewing literature and providing accurate references remains unexplored. This study examines the reliability of references generated by ChatGPT language models in the Head and Neck field. METHODS: Twenty clinical questions were generated across different Head and Neck disciplines, to prompt ChatGPT versions 3.5 and 4.0 to produce texts on the assigned topics. The generated references were categorized as "true," "erroneous," or "inexistent" based on congruence with existing records in scientific databases. RESULTS: ChatGPT 4.0 outperformed version 3.5 in terms of reference reliability. However, both versions displayed a tendency to provide erroneous/non-existent references. CONCLUSIONS: It is crucial to address this challenge to maintain the reliability of scientific literature. Journals and institutions should establish strategies and good-practice principles in the evolving landscape of AI-assisted scientific writing.

Despite refinements to diagnostic and therapeutic approaches over the last two decades, the outcome of patients with head and neck squamous cell carcinoma (HNSCC) has not shown substantial improvements, especially regarding those with advanced-stage disease. Angiogenesis is believed to be a turning point in the development of solid tumors, being a premise for mass growth and potential distant dissemination. Cancer-induced angiogenesis is a result of increased expression of angiogenic factors, decreased expression of anti-angiogenic factors, or a combination of both. The assessment of angiogenesis has also emerged as a potentially useful biological prognostic and predictive factor in HNSCC. The aim of this review is to assess the level of current knowledge on the neo-angiogenesis markers involved in the biology, behavior, and prognosis of HNSCC. A search (between 1 January 2012 and 10 October 2022) was run in PubMed, Scopus, and Web of Science electronic databases. After full-text screening and application of inclusion/exclusion criteria, 84 articles are included. The current knowledge and debate on angiogenesis in HNSCC presented in the eligible articles are stratified as follows: (i) diagnostic markers; (ii) prognostic markers; (iii) predictive markers; and (iv) markers with a potential therapeutic role. Angiogenesis is a biological and pathological indicator of malignancies progression and has negative implications in prognosis of some solid tumors; several signals capable of tripping the "angiogenic switch" have also been identified in HNSCC. Although several studies suggested that antiangiogenic agents might be a valuable adjunct to conventional chemo-radiation of HNSCC, their long-term therapeutic value remains uncertain. Further investigations are required on combinations of antiangiogenic agents with conventional chemotherapeutic ones, immunotherapeutic and molecularly targeted agents in HNSCC. Additional data are necessary to pinpoint which patients could benefit most from these treatments.

Aspirin-exacerbated respiratory disease (AERD) is characterized by eosinophilic asthma, chronic rhinosinusitis with nasal polyps (CRSwNP) and intolerance to cyclooxygenase-1 inhibitors. Interest is emerging in studying the role of circulating inflammatory cells in CRSwNP pathogenesis and its course, as well as their potential use for a patient-tailored approach. By releasing IL-4, basophils play a crucial role in activating the Th2-mediated response. The main aim of this study was to, first, investigate the level of the pre-operative blood basophils' values, blood basophil/lymphocyte ratio (bBLR) and blood eosinophil-to-basophil ratio (bEBR) as predictors of recurrent polyps after endoscopic sinus surgery (ESS) in AERD patients. The secondary aim was to compare the blood basophil-related variables of the AERD series (study group) with those of a control group of 95 consecutive cases of histologically non-eosinophilic CRSwNP. The AERD group showed a higher recurrence rate than the control group (p < 0.0001). The pre-operative blood basophil count and pre-operative bEBR were higher in AERD patients than in the control group (p = 0.0364 and p = 0.0006, respectively). The results of this study support the hypothesis that polyps removal may contribute to reducing the inflammation and activation of basophils.
