Flap perfusion of superficial split flap design for guided bone regeneration: A case report with ultrasonography

Ultrasound imaging technology, being a superior modality for evaluating soft tissue characteristics and able to quantify blood perfusion, is becoming a promising research tool to study oral wound healing. This case report used dental ultrasound to monitor the blood flow of an oral wound for 5 months after a jawbone augmentation procedure. Ultrasound showed gum blood flow peaked at day 3 after the surgery and decreased exponentially until 5 months. Mucosa and muscle may have various blood perfusion recovery patterns than gum tissues that deserve further investigation.
