Surgical strategy for frontal sinus inverted papilloma

Egyptian Journal of Ear, Nose, Throat and Allied Sciences, 2017
Inverted papilloma (IP) is a benign tumor with a local aggressive nature and has a tendency to recur after excision. Despite the evolution of endoscopic techniques in the management of IP, external approaches still play a crucial role in frontal sinus ...

Clinical Anatomy of the Left and Right Atrial Appendages in Humans: Comparative and Developmental Perspective

Clinical Anatomy, EarlyView.
ABSTRACT Human atrial chambers derive from distinct embryonic anlagens, the original embryonic atria gradually transforming into the so‐called auricles, or atrial appendages. This study quantifies macroscopic variations in pectinate muscle architecture in human atrial appendages and evaluates their visualization using clinical imaging modalities.

The Usefulness of Surgical Titanium Microclips for Mucosal Repair in the Frontal Sinus Using ORBEYE: A Technical Note

Neurologia Medico-Chirurgica
Bifrontal craniotomy frequently involves opening the frontal sinus and mucosal injury. We report a new technique for mucosal repair in the frontal sinus using surgical titanium microclips.

Presence of Emissary Veins in the Glabellar Region in Metopic Craniosynostosis

Clinical Anatomy, EarlyView.
ABSTRACT Emissary veins connect intra‐ and extracranial venous circulation by bridging the dural venous sinuses to the external veins of the skull. Their variable presence and location may have important implications in perioperative blood loss. Clinical observations and previous studies suggest that emissary veins are more frequently present in the ...

Guided bone regeneration using CAD‐CAM zirconia barriers: A case series with digital evaluation of bone changes

Clinical Advances in Periodontics, EarlyView.
Background CAD/CAM zirconia barriers represent an advanced option for guided bone regeneration (GBR) in three‐dimensional defects, integrating mechanical stability, biocompatibility, and digital precision. The objectives of this case series were to evaluate, clinically, histologically, and three‐dimensionally, the use of customized zirconia barriers ...

Frontal sinus reconstruction with overlapping sinus mucosa and vascularized pericranial flap Coverage after modified transbasal bifrontal craniotomy: Novel technique and clinical outcomes

World Neurosurgery: X
Background: The modified transbasal bifrontal craniotomy is a variant of the bifrontal craniotomy with a wider surgical corridor than the standard approach. There are several methods for frontal sinus repair in bifrontal craniotomy.

Hemodynamic loading regulates formation and patterning of atrial pectinate muscles in the chick embryo

Developmental Dynamics, EarlyView.
Development and differentiation of the atrial myocardium. Hemodynamic loading triggers shear stress response, which is essential for pectinate muscle formation; mechanical stretching is important for the expression of chamber myocardium markers and proper maturation of the atrial contractile and conductive properties.
