Air pollution (AP) represents one of the main environmental threats to public health and exposure to AP has been connected to upper airway (UA) disease. We evaluated the relationships between the ENT urgent referrals recorded at the Hospital of Padua and the daily levels of particulate matter (PM) as well as other environmental factors in a single year. Patients with UA disorders were included in the study group while those referred for facial trauma or foreign body inhalation formed the control group. Daily PM concentrations, meteorological data and the concentrations of the commonest aeroallergens were obtained. 6368 patients formed the study group and 910 the control one. The concentration of compositae allergens showed a positive effect on the total number of admissions (p = 0.001). PM₁₀ did not demonstrate an effect on the total number of admissions or either the study or control groups admissions (p = 0.25). Alternaria positively influenced admissions of patients in the study group (p = 0.005). Significant relationships were found between the following: PM₁₀ measured on the seventh day before A&E admission and rhinosinusitis (p = 0.007), PM₁₀ on the fifth day and laryngitis (p = 0.01), PM₁₀ on the second day and otitis media (p = 0.03), PM₁₀ on the admission day and epistaxis (p = 0.0198). Our study confirms the causal relationship between aeroallergen concentration and ENT admissions. The levels of PM₁₀ at specific days preceding A&E admission correlated with certain UA disorders. This study strongly points towards the harmful effects of pollution and climate change on UA disease.

Background/Objectives: As precision medicine advances, attention to sex and gender determinants across epidemiological and clinical domains has intensified. However, in the audio-vestibular field, knowledge on sex- and gender-related aspects remains relatively limited. The main aim of this review has been to analyze the available gender medicine-based evidence in vestibular disorders. In particular, our investigation considered the following: (i) pathophysiology and clinical presentation, including differences in predominant signs and symptoms, diagnostic modalities and findings, underlying biological mechanisms associated with vestibular disorders across sex-specific groups; (ii) prognostic variables, including response to treatment, recovery rates, and long-term functional outcomes; (iii) the potential role of sex- and gender-specific diagnostic and therapeutic approaches in the management of vestibular disorders. Methods: Our protocol was registered on PROSPERO (CRD42025641292). A literature search was conducted screening PubMed, Scopus and Web of Science databases. After removal of duplicates and implementation of our inclusion/exclusion criteria, 67 included studies were identified and analyzed. Results: Several studies reported a higher incidence of vestibular dysfunctions among females, with proposed associations involving hormonal fluctuations, calcium metabolism and vitamin D. Estrogen receptors within the inner ear and their regulatory effects on calcium homeostasis have been proposed as potential mechanisms underlying these sex-specific differences. Furthermore, lifestyle factors, comorbidities and differential health-seeking behaviors between males and females may also modulate disease expression and clinical course. Conclusions: Gender-specific variables could not be independently analyzed because none of the included studies systematically reported gender-related data, representing a limitation of the available evidence. Current evidence suggests the presence of sex-related differences in the epidemiology and clinical expression of vestibular disorders, but substantial gaps remain regarding mechanisms, outcomes, and clinical implications. Future research should prioritize prospective, adequately powered studies specifically designed to assess sex and gender influences, integrating biological, psychosocial, and patient-reported outcomes, and adopting standardized sex- and gender-sensitive reporting frameworks.

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.
