Functional outcomes of hyoid suspension in anterior oromandibular reconstruction.

Background: Hyoid suspension can be considered in major oromandibular reconstruction. The impact of hyoid suspension on flap viability, swallowing outcomes, airway, and long term radiographic hyoid position is unknown. The objective of this study is to describe outcomes after hyoid suspension in anterior mandibular reconstruction with fibular free flaps.

Biocompatibility and biodistribution of matrix-bound nanovesicles in vitro and in vivo.

Matrix-bound nanovesicles (MBV) are a distinct subtype of extracellular vesicles that are firmly embedded within biomaterials composed of extracellular matrix (ECM). MBV both store and transport a diverse, tissue specific portfolio of signaling molecules including proteins, miRNAs, and bioactive lipids. MBV function as a key mediator in ECM-mediated control of the local tissue microenvironment.

Ultrasonic cavitation to prepare ECM hydrogels.

Hydrogels composed of extracellular matrix (ECM) have been used as a substrate for 3D organoid culture, and in numerous preclinical and clinical applications to facilitate repair and reconstruction of a variety of tissues. However, these ECM hydrogel materials are fabricated using lengthy methods that have focused on enzymatic digestion of the ECM with an acid protease in an acidic solution; or the use of chaotropic extraction buffers and dialysis procedures which can affect native protein structure and function. Herein we report a method to prepare hydrogels from ECM bioscaffolds using ultrasonic cavitation.
