Inflammatory reaction to hyaluronic acid: A newly described complication in vocal fold augmentation.

A study of the histological behavior of a rabbit vocal fold after a hyaluronic acid injection.

UNLABELLED The vocal fold structure is composed of tissues with many cells surrounded by the extra-cellular matrix. One of the most important components of the extra-cellular matrix is Hyaluronic Acid (HA). The aim of the study was to evaluate the inflammatory response of rabbit vocal folds after a local injection of Restylane HA. METHODS Twelve adult male rabbits randomly received a 0.1 ml i...

Detection of hyaluronic acid receptor in human vocal folds by immunohistochemistry.

UNLABELLED Hyaluronic acid receptor is a glycoprotein of the plasmatic membrane, and the CD44 is its representative, expressed in many cell types where it has the task of cell adhesion. AIM the goal of the present experimental study is to investigate the possibility of using immunohistochemistry to identify the distribution of hyaluronic acid along the vocal fold. MATERIALS AND METHODS We r...

Three-dimensional hydrogel model using adipose-derived stem cells for vocal fold augmentation.

Adipose-derived stem cells (ASCs) may provide a clinical option for rebuilding damaged superficial lamina propria of the vocal fold. We investigated the effects of five hydrogels (hyaluronic acid [HA], collagen, fibrin, and cogels of fibrin-collagen and fibrin-HA) on the differentiation of ASCs, with the long-term goal of establishing the conditions necessary for controlling the differentiation...

A case of complication after matridex(r) injection.

Matridex(R) is an injectable skin filler that's composed of a mixture of cross linked hyaluronic acid and dextranomer particles, and it was recently developed for soft tissue augmentation. To the best of our knowledge, there have been few previous reports on complications associated with Matridex. We report here on a delayed inflammatory reaction to an injection of Matridex in the glabellar fol...
