Purpose of review: The purpose of this review is to share the implementation of an integrated care systems approach for head and neck cancer speech and language therapy services. Facilitating factors and barriers to change are highlighted and links to relevant literature are indicated. The intention is that this paper will provide a 'non blueprint' for others embarking on large scale integrative change.

Recent findings: Integrating health and social care provision across organizations is necessary for improving outcomes for people, reducing health inequalities and improving efficiencies in care. Whilst recognizing this intention, the current structure for providing care in NHS organizations does not foster cross-organizational working.

Summary: Integration enhances patient centred care, however implementation of change across organizations is challenging. Managerial support is pivotal and differences in organizational culture need to be acknowledged, respected and overcome. A clearly defined vision, to which all staff are committed provides an anchor in challenging situations. Transformational change is iterative and cannot always be predetermined. Success is possible; tenacity, flexibility and agility are key.

Purpose of review: This review aims to provide a comprehensive analysis of skull base osteoradionecrosis (ORN), a severe and rare complication of radiotherapy for head and neck malignancies. It explores pathogenesis, clinical presentation, diagnostic strategies, and management approaches, emphasizing the importance of multidisciplinary care in addressing this challenging condition.

Recent findings: Skull base ORN results from radiotherapy-induced tissue damage, characterized by hypovascularity, hypoxia, and necrosis, often compounded by secondary infections. Advances in radiotherapy techniques, such as intensity-modulated radiotherapy and heavy particles, have reduced ORN incidence, though cases persist, particularly in high-dose radiotherapy fields. Emerging treatments, including hyperbaric oxygen therapy and the pentoxifylline-tocopherol protocol, show promise but lack robust evidence for standardized use. Surgical interventions, especially those incorporating vascularized tissue reconstruction, have demonstrated favorable outcomes in refractory cases. Recent studies underscore the utility of multimodal imaging techniques, including MRI and PET/CT, for distinguishing ORN from tumor recurrence.

Summary: Skull base ORN represents a complex and potentially life-threatening condition requiring tailored, multidisciplinary management. Although advancements in diagnostics and therapeutics have improved outcomes, significant challenges remain, particularly in developing standardized protocols. Further research is needed to refine treatment strategies and improve evidence-based practices for this entity.

Purpose of review: Nasoseptal flaps are a frequently used and well characterized means of reconstruction following endoscopic endonasal approach surgery (EEA). However, there are alternative means of reconstruction, including the extracranial pericranial flap (ePCF), that while used infrequently fulfill a specialized need in larger or salvage reconstructions. This review aims to better characterize long-term outcomes using ePCF where there is currently a paucity of objective data on use and outcomes.

Recent findings: A traditional pericranial flap involves elevating and rotating the flap through a craniotomy defect to reconstruct defects of the ventral skull base. The ePCF is implemented without performing a craniotomy, and instead tunnels the flap through a bony opening created at the level of the nasion. This review presents outcomes in a large single-center cohort of patients with ePCFs to better characterize the short- and long-term success, risks, and complications of this reconstructive method.

Summary: Long-term follow-up demonstrates that obstruction of the frontal sinus outflow may occur but rarely requires surgical intervention. ePCF are a reasonable alternative to consider in cases where local tissue would be insufficient, is not available, or has already failed. There is a low risk of flap complications.

Purpose of review: This review examines the impact of skull base surgery on olfactory function, a critical yet often overlooked aspect of postoperative quality of life. As surgical techniques continue to evolve, understanding their impact on olfaction is key to optimizing patient outcomes.

Recent findings: The relationship between skull base surgery and olfactory function continues to be debated in the literature. With the adoption of transnasal surgical approaches, a significant concern has been its impact on olfaction. Prior studies have shown evidence of olfactory dysfunction following transnasal skull base surgery, though these findings are not universal. A particular area of discussion involves the use of the pedicled nasoseptal flap, which has demonstrated potentially negative short-term olfactory impacts. Additional concerns surround flap design (olfactory strip preservation) and technique of flap harvest (cold knife versus electrocautery). Evidence suggests that olfactory strip preservation may effectively maintain postoperative olfactory performance, while cold knife techniques offer no clear advantage over electrocautery.

Summary: The inconsistencies in the literature underscore the need for standardized, large-scale studies that directly compare surgical techniques to better understand the impact of transnasal skull base surgery on olfaction. This is essential to optimizing surgical outcomes and improving patient quality of life postoperatively.

Purpose of review: Especially with the advent of biologics which have originally been prescribed primarily for pulmonary disease, the interconnections between asthma and chronic rhinosinusitis are becoming even more apparent. Biologics can now also be prescribed for chronic rhinosinusitis in some countries. But what is the epidemiology, pathophysiology and treatment of both diseases?

Recent findings: This review covers the epidemiology, pathophysiology, morbidity and treatment of both diseases. Specifically, this review highlights the interdependencies of both diseases and potential future treatment options.

Summary: This review aims to alert physicians to go beyond treating only one of the diseases, but rather to get a broader picture of the diseases and treatment options.

Purpose of review: The purpose of this opinion is to review current evidence regarding postoperative management following endoscopic skull base surgery.

Recent findings: Postoperative management encompasses consideration of level of care, laboratory tests, analgetic and antiemetic therapy, antibiotic, antithrombotic and antiepileptic prophylaxis, pharmacological and nonpharmacological cerebrospinal fluid (CSF) pressure reduction measures, including CSF diversion, activity restrictions, nasal packing removal, nasal debridement and toilet, nasal glucocorticoid administration, positive pressure ventilation, imaging, CSF leak diagnosis, and future perspectives.

Summary: Although significant effort has been put into research of postoperative measures after endoscopic skull-base surgery, there is a heterogeneity of practices and deficit of high-level studies, which would enable highly powered systematic reviews and meta-analyses.

Purpose of review: This article provides a comprehensive review of the computed tomography (CT) and magnetic resonance (MR) imaging findings of invasive fungal sinusitis with an emphasis on pattern recognition and approach to interpretation.

Recent findings: Fungal sinusitis is categorized into invasive (acute, chronic, and granulomatous) and noninvasive forms (allergic fungal sinusitis and mycetoma). CT is superior for detecting bony erosion and hyperdense fungal elements, while MRI excels in evaluating soft tissue and mucosal involvement. Key radiologic signs such as bone destruction, sinus wall thickening, and 'black turbinate sign' aid in early diagnosis, especially in invasive cases. Early imaging signs can be subtle. Early detection is necessary, particularly in immunocompromised patients with acute invasive fungal sinusitis, where rapid intervention is critical.

Summary: Pattern recognition and adequate interpretation of fungal sinusitis are possible using CT and MRI. Imaging can also help identify complications, aiding with reliable diagnosis and prompt intervention.

Purpose of review: Olfactory neuroblastoma (ONB) is a rare malignancy originating from olfactory neuroepithelial cells. Given its uncommon nature and complex clinical presentation, this comprehensive review highlights recent findings and treatment approaches for advancing clinical practice and research.

Recent findings: Recent literature emphasizes significant advancements in the genomic profiling and molecular classification of ONB. Emerging targeted therapies include somatostatin analogs and programmed death-ligand 1 (PD-L1) inhibitors. In addition, the development of genetically engineered mouse models has provided valuable platforms for testing new treatment strategies, revealing similarities between ONB and small cell lung cancer, which may inform future therapeutic approaches.

Summary: These findings have profound implications on clinical practice. Improved diagnostic accuracy through advanced imaging and genomic profiling in addition to identifying specific mutations for targeted therapy can lead to personalized treatments of patients with ONB. Developments in genetically engineered mouse models and multiinstitutional collaborative efforts are vital for advancing research and standardizing molecular testing. The integration of advanced imaging techniques, genomic profiling, and targeted therapies holds promise for improving patient outcomes and understanding this rare malignancy.
