Selective Scalp Nerve Block: A Useful Technique With Tissue Expansion in Postburn Pediatric Alopecia.

Background: Scalp defects can be reconstructed either with skin graft, local flaps, free flaps, or tissue expansion. Tissue expanders have been proved to be fruitful in the pediatric population. Scalp expansion has proved to be useful in the reconstruction of posttraumatic and postburn alopecic defects.

Sural artery perforator flap with posterior tibial neurovascular decompression for recurrent foot ulcer in leprosy patients.

The sensory loss and alteration of the shape of the foot make the foot liable to trauma and pressure, and subsequently cause more callus formation, blisters, and ulcers. Foot ulcers usually are liable to secondary infection as cellulitis or osteomyelitis, and may result in amputations. Foot ulcers are a major problem and a major cause of handicaps in leprosy patients.
