A Robust Bio‐Supportive Hydrogel Patch for Full‐Thickness Repair of Gastroesophageal Defects
Advanced Science, EarlyView.Gastroesophageal defect repair remains a formidable clinical challenge plagued by high leakage and life‐threatening complications. We develop a double‐disc, highly crystalline PVA‐based RBS hydrogel patch featuring suture‐free sealing, robust acid/enzyme resistance and mechanical durability.

Advanced Energy Materials, EarlyView.Adopting a scalable hybrid two‐step deposition process route, textured perovskite/silicon tandem solar cells achieve over 30% power‐conversion efficiency. The process route replaces all non‐scalable spin‐coating steps, including organic precursor deposition, self‐assembled monolayer formation, and passivation layer deposition, with scalable techniques ...

Advanced Energy Materials, EarlyView.Chemical rounding transforms irregular submicron silicon textures into more favorable interfaces for perovskite–silicon tandems. Suppressed local epitaxial ordering improves bottom‐cell passivation, while the top‐cell stack exhibits a higher and more spatially uniform quasi‐Fermi‐level splitting, enabling monolithic tandem solar cells with an ...

International Forum of Allergy &Rhinology, EarlyView.ABSTRACT Background Healing dynamics after anterior skull base (ASB) reconstruction following transnasal endoscopic surgery (TES) for sinonasal malignancies remain poorly characterized. This study aimed to describe the postoperative healing process, quantify time to healing, identify factors influencing healing, and assess radiologic evolution over ...

Journal of the American Medical Association, 1911 In cases of empyema of the frontal sinus in which the removal of the middle turbinate and ethmoid cells fail to give sufficient drainage to relieve the condition, it is often necessary to enlarge the opening into this sinus. For this operation I have had made a curette, which I have used with success in a great many cases, the exact sizes and curve of ...

International Forum of Allergy &Rhinology, EarlyView.ABSTRACT Introduction Traditional management of traumatic skull base dural injury has often favored observation and conservative therapy, despite the risk of delayed intracranial complications. This paradigm originated when operative intervention required craniotomy and carried significant morbidity.

Delayed endoscopic assisted percutaneous reduction of anterior table frontal sinus fractures
Otolaryngology Case Reports, 2021 Endoscopic approaches to the management of frontal sinus fractures continue to become more commonplace. Anterior table fractures amenable to reduction by these techniques are optimally managed within the first five to ten days to avoid fibrosis of the ...

International Forum of Allergy &Rhinology, EarlyView.ABSTRACT Background Sinus and skull base surgery create areas of demucosalized bone and cartilage in the sinonasal cavity, yet no standardized system exists to describe the progressive healing of these wounds. The goal of this study was to develop the novel Sinonasal Assessment of Reepithelialization (SNARE) and perform parametric testing including ...

Severe pneumocephalus following cranioplasty: Approach and review of the literature
Otolaryngology Case Reports, 2021 Objective: To present a case of significant persistent pneumocephalus following failed cranialization of the frontal sinus. Case report: We describe the case of a 58-year-old female with a history of hemorrhagic stroke requiring emergent craniotomy which

Journal of Mahatma Gandhi Institute of Medical Sciences, 2018 Osteomas are benign, slow-growing tumors found commonly in craniomaxillofacial region. Clinically, they may remain asymptomatic because of their small size or may become symptomatic because of enlargement, erosion, or compression of structures in the vicinity.
