Heterotopic ossification in orbital roof, frontal sinus, and ethmoidal cells leading to hypoglobus and upward-gaze deficit.

Heterotopic ossification (HO) of facial sinuses is very rare. In this article, we present an extensive HO case covering the right frontal sinus, superior ethmoidal cells, and upper orbital rim and roof. This mass was leading to a hypoglobus and upward-gaze deficit due to mass effect.

The effects of combined application of autogenous fibroblast cell culture and full-tissue skin graft (FTSG) on wound healing and contraction in full-thickness tissue defects.

Introduction: This study investigates the effects of culture grown fibroblasts on contraction and dermal regeneration when used concurrently with full-thickness skin graft (FTSG) in full-thickness wounds.

Materials And Methods: Fourteen Sprague-Dawley male rats were divided into two groups. In the first group, wound contraction was evaluated visually.

Rat tail revascularization model for advanced microsurgery training and research.

We describe a time-saving microsurgical exercise for continuing microsurgical training and research. The rat tail replantation model was simplified by excluding bone detachment. Rats were divided into two groups: devascularization only ( N = 3) and revascularization after devascularization ( N = 7).
