Infantile digital fibromatosis: an unusual localization.

Infantile digital fibromatosis (recurrent digital fibromatosis) is a rare, benign fibrous growth of childhood. The authors present a case of a 16-year-old child with an infantile digital fibromatosis on the volar surface of the right little finger at the distal interphalangeal joint level. After excision of the tumor, histopathologic diagnosis was shown to be infantile digital fibromatosis. The patient has been free of recurrence for 3 years after surgery.

Bilateral, extended V-Y advancement flap.

A modification of the V-Y advancement flap for the closure of circular skin defects is presented to decrease the tension in the closure and to break the midline vertical scar. Bilateral, extended V-Y advancement flaps with additional limbs extending to the advancing edges of the standard flaps were marked on both sides of the wound. After advancement of the V-Y flaps on their subcutaneous pedicle, the upper and lower extensions were hinged downward as transposition flaps to close the middle portion of the circular defect, where maximum tension occurs. This procedure was applied to 10 patients with sacral and trochanteric pressure sores. No complications or recurrences were noted during the 2 to 10 months of follow-up. Bilateral, extended V-Y advancement flaps enable the reconstruction of large defects without midline tension. Also, the resulting scar where the flaps meet is a zigzag line, so a straight midline scar is avoided.

Innervated dorsal adipofascial turnover flap for fingertip amputations.

Traumatic or thermal injury to the fingertip may result in composite tissue loss. Exposed tendon, bone, or joint surface is best treated by flap coverage. The authors present their experience with a new technique that provides coverage for fingertip defects using the innervated dorsal adipofascial turnover flap, which consists of adipofascial tissue only and relies on the arterial anastomotic network of this tissue layer to sustain its vascularization. Eight digital amputations between the distal phalanx proximal to the nail matrix and midportion of the middle phalanx were resurfaced successfully with the innervated dorsal adipofascial turnover flap. The flaps survived completely; the mean follow-up was 9 months. This technique seems to be a relatively simple way of achieving early recovery. It does not require the use of distant flap immobilization of adjacent digits, nor does it require the use of homodigital flaps, which may jeopardize an already injured finger. The main advantages of the innervated dorsal adipofascial turnover flap are its ready availability from the local tissue, its sensation, and the absence of functional and aesthetic disturbance at the donor site.

Which dressing for split-thickness skin graft donor sites?

There are a variety of methods used for the postoperative management of the donor site created after harvesting a split-thickness skin graft. The authors compare three major groups of dressings-open, semiopen, and closed-performed on 60 patients divided into three groups. These different dressings were compared based on healing time, quality of the regenerated skin, and patient comfort. Biopsy specimens were obtained from the donor sites of each group for the assessment of healing quality and stage. An ideal donor site dressing method is one that affords protection from dehydration and prevention of wound and infection while also achieving rapid and painless healing of the donor site. The closed-dressing group had the shortest healing time, shown both clinically and histologically, and superior patient comfort was also documented in this group. The closed-dressing group showed qualitatively superior healing when compared with open and semiopen donor sites. This was attributed to protection from dehydration and mechanical trauma, and avoidance of exogenous contamination.

"Pac Man" flap for closure of pressure sores.

The purpose of this study was to modify the classic bilateral V-Y advancement flap procedure to decrease the tension in its closure and to break the midline vertical scar by interdigitating the flaps. After debridement of a pressure sore, the V-Y flaps were marked on both sides of the wound. Skin incisions were carried down to the muscle fascia along the sides of the flaps. The upper and lower limbs of the V-shaped flaps were elevated as triangular flaps but remained attached to the main flap. The tip of the upper limb of one of the flaps was transposed into the defect and sutured to the contralateral V-Y flap at the midpoint of its concave side facing the defect. The lower limb of the contralateral flap was then transposed into the defect and sutured to the first V-Y flap. To complete the interdigitated closure, the lower limb of the first flap was sutured below the contralateral flap, and the upper limb of the contralateral flap was sutured above the first flap. The final view of the flaps was similar to "Pac Man," so the authors decided to call this flap the Pac Man flap. The flaps healed well in all patients, and wound breakdown or recurrence of the pressure sore was not observed during the 3 to 14-month follow-up.

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.

Prophylactic antibiotics in plastic and reconstructive surgery.

There is no consensus in the literature on the use of prophylactic antibiotics to prevent postoperative infection. This study was performed to investigate whether the use of prophylactic antibiotics has an effect on postoperative infection rates. A total of 1400 patients were classified into four groups based on their diagnosis. During the induction of anesthesia, half of each group received 2 g of a sulbactam-ampicillin combination and the other half received a placebo (saline solution) intravenously. Wound infection rates were observed in the postoperative period. Age, sex, and operative site of the patients with the same diagnosis were comparable in each group. The white blood cell count and the body temperature reading of each patient were recorded postoperatively. Wounds were observed daily in the postoperative period and graded according to a predetermined scale. Bacteriologic specimens were obtained from patients who had wound infections. According to our clinical experience, antibiotic prophylaxis is not necessary in plastic surgery. At the end of our 6-year study, a significant difference could not be found between the antibiotic prophylaxis and placebo groups.

Tangentially split gluteus maximus myocutaneous island flap based on perforator arteries for the reconstruction of pressure sores.

From 1995 to 1997, the authors used tangentially split gluteus maximus myocutaneous island flaps based on the musculocutaneous perforator arteries for the reconstruction of pressure sores located in the trochanteric, sacral, and ischial regions of 30 ambulatory and paraplegic patients. The postoperative follow-up period was 18 months. Postoperative electromyograms were performed on the ambulatory patients to compare the function of the gluteus maximus muscles on each side. There were one major and two minor postoperative complications. There was no total flap loss. The major advantage of this technique is the preservation of most of the gluteus maximus for stair climbing and single-limb support in the ambulatory patient. The tangentially split gluteus maximus myocutaneous island flap is recommended as the procedure of choice for closure of sacral, ischial, and trochanteric ulcers in both the ambulatory and nonambulatory patient.

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.

Septo-orbitoperiostoplasty for the treatment of palpebral bags: a 10-year experience.

The orbital region is sensitive to the undesirable effects of any surgical intervention, because of its anatomical location and the importance of the eyelids in facial sign language. The procedures performed for correction of baggy eyelids may have remarkable undesired results. In recent years, we have made a special effort to analyze the causes, to minimize these undesirable effects, and to be able to offer patients more natural and safer results. We have designed a new technique called septo-orbitoperiostoplasty for the treatment of baggy eyelids, based on preservation of orbital fat and correction of the supportive layer. This technique consists of placing the orbital fat back into the orbital cavity and its retention by suturing the lax septum to the periosteum of the orbital rim. Neither an incision on the orbital septum nor an excision of the orbital fat is performed. It can be performed for both upper and lower eyelids. This paper describes the surgical procedure and shows the results obtained from 74 patients who had been treated with this technique over a 10-year period. All patients were followed up for an average of 5 years.

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.
