Article Abstract
The treatment of skull base paragangliomas has moved towards the use of cranial nerve preservation strategies, using radiation therapy and subtotal resection in instances when aiming for gross total resection would be expected to cause increased morbidity compared to the natural history of the tumor itself. The goal of this study was to analyze the role of surgery in patients with skull base paragangliomas treated with CyberKnife stereotactic radiosurgery (SRS) for definitive tumor control. A retrospective review identified 22 patients (median age 65.5 years, 50% female) treated with SRS from 2010-2022. Fourteen patients (63.6%) underwent microsurgical resection. Gross total resection was performed in four patients for tympanic paraganglioma ( = 2), contralateral paraganglioma ( = 1), and intracranial tumor with multiple cranial neuropathies ( = 1). Partial/subtotal resection was performed for the treatment of pulsatile tinnitus and conductive hearing loss ( = 6), chronic otitis and otorrhea ( = 2), intracranial extension ( = 1), or episodic vertigo due to perilymphatic fistula ( = 1). Eighteen patients had clinical and imaging follow-up for a mean (SD) of 4.5 (3.4) years after SRS, with all patients having clinical and radiological tumor control and no mortalities. Surgery remains an important component in the multidisciplinary treatment of skull base paraganglioma when considering other outcomes besides local tumor control.

Skull base reconstruction is a critical component of endoscopic endonasal skull base surgery (EESBS). Bed rest remains an indispensable element of post-operative care, which should be carefully considered for reducing the risk of cerebrospinal fluid (CSF) leaks and enhancing surgical outcomes (1, 2). However, the necessity of bed rest continues to be controversial as indicated by the expert consensus on perioperative management of skull base reconstruction, due to a lack of high-quality evidence to support its effectiveness (1-4).

Background: Criteria for biologic treatment of uncontrolled severe chronic rhinosinusitis with nasal polyps (CRSwNP) differ across international recommendations and prescription of biologics depends on national reimbursement criteria. CHRINOSOR offers an opportunity to analyse biologic indications in the real-world setting according to international recommendations.
Methods: CRSwNP patients who received dupilumab treatment in the ENT clinic of 6 tertiary centres (5 countries) were included.

Introduction: The airway mucosa plays a crucial role in protection and various physiological functions. Current methods for restoring airway mucosa, such as myocutaneous flaps or split skin grafts, create a stratified squamous layer that lacks the cilia and mucus-secreting glands of the native columnar-lined airway. This study examines the application of various injectable biopolymers as active molecules for a potential approach to regenerating laryngeal epithelial tissue.

Biology-guided voxel-level inverse prescription mapping for dose painting (DP) using diffusion-weighted magnetic resonance imaging was evaluated for technical feasibility in proton therapy for 10 skull-base chordoma patients. Patient-specific DP prescriptions were generated from tumour cellularity and implemented in a clinical treatment planning system. Compared with uniform plans, DP achieved lower conformity (although >97 %), improved target dose metrics, reduced doses to most organs at risk, and increased tumour control probability without exceeding clinical constraints.

Background: Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma of childhood. For stratification purposes, rhabdomyosarcoma is classified into fusion-positive RMS (alveolar rhabdomyosarcoma) and fusion-negative RMS (embryonal or spindle cell/sclerosing, FN-RMS) subtypes according to its fusion status. This study aims to highlight the pathologic and molecular characteristics of a cohort of FN-RMS using a targeted NGS RNA-Seq assay.
