Ectopic olfactory neuroblastoma is associated with increased frequency of syndrome of inappropriate antidiuretic hormone secretion and reduced disease control: Case series with systematic review and pooled analysis.

Introduction: Olfactory neuroblastoma (ONB) is a rare malignant tumor originating from the olfactory neuroepithelium, typically within the sinonasal cavity. Cases of ONB originating outside of the olfactory cleft area are extremely rare and are referred to as "ectopic" (eONB), in contrast to "orthotopic" tumors (oONB). ONB has been associated with paraneoplastic syndromes (PNSs), including the syndrome of inappropriate antidiuretic hormone secretion (SIADH).

Responders to biologics in severe uncontrolled chronic rhinosinusitis with nasal polyps: a multicentric observational real-life study.

Background: Clinical trials have demonstrated the effectiveness of biologics in treating chronic rhinosinusitis with nasal polyps (CRSwNP). However, real-world evidence regarding patient outcomes and predictors of clinical response remains limited.

Methodology: In this multicentric 18-month follow-up study, 326 adult patients who initiated biologic therapy for severe uncontrolled CRSwNP were included.

Enlarged Frontal Sinusotomy and Chronic Rhinosinusitis with Nasal Polyps: An Effective Strategy to Control the Disease.

Introduction: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a disease with a strong impact on the quality of life (QoL) which treatment is based on local intranasal corticosteroids (ICS) and iterative courses of systemic corticosteroids (SCS) in case of relapse. When medical treatment is insufficient, surgery is indicated. We investigated the impact of enlarged frontal sinusotomies (EFS: Draf IIb or Draf III) on QoL and annual SCS consumption of patients with severe uncontrolled CRSwNP.

Pott's Puffy Tumor in Young Age: A Systematic Review and Our Experience.

Salvage surgery in nasopharyngeal Cancer: Unraveling the efficacy of transnasal endoscopic nasopharyngectomy for advanced stage recurrent tumors.

Objective: This systematic review evaluates the efficacy and morbidity of transnasal endoscopic nasopharyngectomy as a salvage treatment for advanced-stage recurrent nasopharyngeal carcinoma (rNPC).

Methods: Following PRISMA guidelines, we conducted a systematic search in Medline, Scopus, and PubMed, identifying studies on transnasal endoscopic nasopharyngectomy for rNPC. Inclusion criteria encompassed histologically confirmed rT3 and rT4 NPC patients previously treated with radiotherapy or chemoradiotherapy.

Using learning-by-concordance to develop reasoning in epistaxis management with online feedback: A pilot study.

Background: Epistaxis is a recurring cause for referral to emergency departments. Its management can be complex; hence, it is critical to provide appropriate support to Otolaryngology-Head and Neck Surgery (OHNS) residents to develop clinical reasoning skills to manage such cases. Learning-by-Concordance (LbC) is a recently developed educational tool that encourages learners to think through simulated clinical scenarios.

Artificial intelligence for automatic detection and segmentation of nasal polyposis: a pilot study.

Purpose: Accurate diagnosis and quantification of polyps and symptoms are pivotal for planning the therapeutic strategy of Chronic rhinosinusitis with nasal polyposis (CRSwNP). This pilot study aimed to develop an artificial intelligence (AI)-based image analysis system capable of segmenting nasal polyps from nasal endoscopy videos.

Methods: Recorded nasal videoendoscopies from 52 patients diagnosed with CRSwNP between 2019 and 2022 were retrospectively analyzed.

Intralesional cidofovir injections for the treatment of multifocal exophytic sinonasal papilloma.

Intralesional cidofovir injections in combination with surgery is an effective treatment for recurrent multifocal sinonasal exophytic papilloma. No malignant transformation has been observed in our experience. Anosmia is a potential side effect that patients should be aware of.

Dupilumab: a delayed response in asthmatic and atopic patients treated for chronic rhinosinusitis with nasal polyps.

Purpose: Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) is a common disease, which was previously approached with sinus surgery or systemic corticosteroids. The advent of biological therapies radically changed the approach to this disease. On the other hand, there is scarce scientific evidence of how specific subsets of patients respond to this treatment.

Endovascular coils extrusion after internal carotid artery occlusion: From management to follow-up.

ICA coil extrusion (ICA-CE) occurs most frequently in the nasopharyngeal/sinonasal site. Evaluating the ICA coils stability, through an angiography, is of primary importance. ICA-CE management needs to be decided based on the patient's symptoms and general status.

Iatrogenic Cerebrospinal Fluid Leak in Endoscopic Sinus Surgery: Topographical Map and Influence of Skull Base Asymmetry.

Background: Iatrogenic cerebrospinal fluid leak (iCSF-L) is a major complication of endonasal surgeries whose occurrence is always a potential adverse event due to anatomical variation/asymmetry of the skull base (SB). The aim of this manuscript is to provide a topographical map of iCSF-L and to investigate the role of SB asymmetry in iCSF-L occurrence.

Methods: In this retrospective study, the location of iCSF-L dural defect was studied and compared to patients affected by spontaneous and post-traumatic CSF-L.
