Management of chronic rhinosinusitis with nasal polyps in the Asia-Pacific region and Russia: Recommendations from an expert working group.

Chronic rhinosinusitis with nasal polyps (CRSwNP) is a chronic inflammatory condition of the nasal and paranasal tissues, characterized by the presence of bilateral nasal polyps. An expert panel of specialists from the Asian-Pacific region and Russia was convened to develop regional guidance on the management of CRSwNP through a consensus approach. The present article presents the chief observations and recommendations from this panel to provide guidance for clinicians in these areas.

Case Report: Oncocytic Schneiderian Papilloma Originating From the Sphenoid Sinus.

A rare case of oncocytic Schneiderian papilloma originating from the sphenoid sinus characterised, for 3 years, by non-specific symptoms of severe headache, a block of nasal breathing, and deprecating sense of smell was presented by an elderly female patient. Sphenoid sinus functional endoscopic sinus surgery (FESS), with a one-block tumour excision, through an endonasal approach, with a histological study of removed tumour masses, were performed on the patient. Long observation in the post-operative period was necessary, considering the risk of recurrence and malignancy of oncocytic Schneiderian papilloma (OSP).

A follow-up study of mucociliary clearance and trace element and mineral status in children with chronic rhinosinusitis before and three months after endoscopic sinus surgery.

Background: The existing data demonstrate the potential role of trace elements in nasal mucociliary clearance, although the association between trace element and mineral status and ciliary function in children with chronic rhinosinusitis is insufficiently studied. Therefore, the objective of the present study is evaluation of trace element and mineral status and mucociliary function in pediatric CRS patients before and after functional endoscopic sinus surgery.

Methods: The present study involved 30 children with chronic rhinosinusitis without nasal polyps.

Comparative Analysis of Mucociliary Clearance and Mucosal Morphology Using High-Speed Videomicroscopy in Children With Acute and Chronic Rhinosinusitis.

Objective: evaluation of mucociliary clearance and mucosal morphology using high-speed videomicroscopy, and their association with markers of disease severity in children with acute (ARS) and chronic rhinosinusitis (CRS).

Methods: A total of 67 children aged from 6 to 17 years including 15 healthy children, 20 pediatric patients with acute rhinosinusitis, and 32 cases with chronic rhinosinusitis were enrolled in the present study. SNOT20, Lund-Kennedy, and Lund-Mackay scores were also evaluated.

Serum, Whole Blood, Hair, and Mucosal Essential Trace Element and Mineral Levels in Children with Verified Chronic Rhinosinusitis Undergoing Functional Endoscopic Sinus Surgery.

The objective of the present study was to assess hair, serum, whole blood, and excised tissue essential element content in children with chronic rhinosinusitis (CRS). Eighty-eight children with chronic rhinosinusitis and 66 healthy controls were enrolled in the present study. Evaluation of endoscopic Lund-Kennedy and computed tomography Lund-Mackay scores, as well as tissue sampling, was performed only in children with chronic rhinosinusitis.

Comparative analysis of the outcome of external and endoscopic frontal sinus surgery in children.

Both open and functional endoscopic sinus surgery (FESS) are performed in the case of pediatric frontal rhinosinusitis. However, data from comparative analysis of these surgery types are insufficient. Prospective randomized trial for comparison of open and endoscopic surgery outcome in pediatric chronic rhinosinusitis.
