This study aimed to evaluate soft tissue adaptation in Class II Division 1 malocclusion patients treated with four premolar extractions and fixed appliances, focusing on the correlation between anterior teeth retraction and soft tissue changes.

Soft tissue defects of the lower leg and foot are complicated injuries with numerous causes including trauma, ulcers, and Gout. Objectives: 1. To construct a map of the perforators of the peroneal artery and posterior tibial artery using a handheld Doppler ultrasound. 2. To evaluate the clinical outcome of perforator flaps to cover soft tissue defects in the lower leg and foot.
