Recurrent interdigital pilonidal sinus treated with dorsal metacarpal artery perforator flap.

A 39-year-old otherwise healthy barber presented to our clinic complaining of frequent periods of swelling and purulent discharge in his second and third right web spaces. An excision was performed after administration of methylene blue to visualize the extent of both cysts located in his second and third web spaces. A distally based dorsal metacarpal artery perforator flap was chosen to close the defect on his second web space. Interdigital pilonidal sinus is a rare disease caused by repeated implantation of foreign hair to the interdigital web space. In secondary cases or in cases where an extensive resection has to be done in order to completely remove the cysts, closure with a skin flap can become compulsory. Dorsal metacarpal artery perforator flap is a good choice with minimal donor site morbidity and this flap might provide robust skin coverage which can possibly avoid further penetration of hair in to web space.

Dorsal adipofascial turn-over flap for fingertip amputations.

We designed a dorsal adipofascial pedicled flap to cover amputations of the tip of the same digit. This flap includes all the adipofascial tissues from the dermis to the paratenon of the extensor tendons. After elevation of the skin, the adipofascial tissues are raised as a flap and turned over to resurface the exposed bone or joint and then covered with a split thickness skin graft. Ten digital amputations between the distal phalanx proximal to the nail matrix and the mid portion of the middle phalanx were successfully resurfaced with dorsal adipofascial turn-over flaps. All flaps survived completely and the mean follow-up was 11 months. This one-step procedure would seem to be a relatively simple way of achieving early recovery because it does not require the use of distant flaps immobilization of adjacent digits, or homodigital flaps that might jeopardize an already injured finger.

Reconstruction of mandible with fibula free flap.

The fibula can be used as a donor for a free flap for mandible reconstruction. It has the advantages of low donor site morbidity, consistent shape, ample length, and distant location to enable a two-team approach, allowing multiple osteotomies because of its periosteal circulation. It can be raised with a skin island for composite tissue reconstruction. Eight segmental mandibular defects (average 11.62 cm) were reconstructed following resection for tumour. Six defects consisted of bone alone and the other two had only a small amount of associated intraoral soft-tissue loss. Two patients underwent primary reconstruction. We performed two or three osteotomies on each graft and used miniplates and wires for bone fixation. The flaps survived in all patients. All osteotomy sites healed primarily. The aesthetic result of reconstruction was satisfactory.

Double opposing semicircular flap: a modification of opposing Z-plasty for closing circular defects.

A new method is presented for the closure of circular skin defects without altering their original shapes and excision of additional healthy skin. The authors hypothesized that two semicircular flaps prepared from opposite sides of a circular defect could close the defect without additional healthy tissue excision from the defect or the raised flaps; this technique was called double opposing semicircular flaps. It was first studied on an animal model followed by application on our patients with satisfactory results. This procedure has been performed with success on various body surfaces for defects of a size range of 2 to 5 cm in diameter. In this article, technical details and four clinical cases are presented.
