Uses of scapular island flap in pediatric axillary burn contractures [correction of conractures].

Pediatric axillary post-burn contractures one of the most challenging problems which follow treatment of the upper extremity burns. We preferred to use scapular flaps for surgical treatment of pediatric axillary contractures instead of skin grafting or Z-plasties. In this clinical study we present 13 pediatric cases treated with scapular island flaps. In pediatric scapular flap cases, the technique which we used was to extend the flap's pedicle dissection was continued to the level of bifurcation of subscapular artery. Bypassing the flap triangular space allowed us to cover the anterior part of the axillary contractures. We observed that the scapular flap repairs have many benefits to skin grafting including no recurrence of contracture and stable coverage of the shoulder joint. The other advantages of scapular island flap are that the donor site is closed primarily, and it provides an adequate amount of pliable skin while not compromising the function and range of motion of joints. In conclusion, the island scapular flap is a good choice for reconstruction of various axillary contractures in pediatric population.

Reconstruction of the anterior surface of the ear using a postauricular pull-through neurovascular island flap.

The auricular conchal cavity is a shallow structure in the central part of the ear. It is not only 3-dimensional, but it is a gateway to the external ear canal. Many methods have been described for reconstruction of the defect of concha-antihelix: split- or full-thickness skin grafts, regional skin, chondrocutaneous and musculocutaneous flaps, but none of the authors have described this flap with neurovascular pedicle. We used postauricular neurovascular pedicle island flap for conchal and periconchal areas of anterior surface of the external ear because it matches to the skin color, thickness and texture; scars are well hidden, and there is no donor-site morbidity. Moreover, it has a constant and reliable neurovascular pedicle. The flap edema which was present in the early postoperative period began to resolve gradually after 3 weeks and disappeared in a few months. The esthetic results were excellent in all of the patients and very satisfying for the patients, too. The sensibility was positive by light touch, pin-prick, temperature and static 2-point discrimination in the postoperative control. The static 2-point discriminations in the transferred flap and in the other ear, which corresponds to the same area, were measured. The results were nearly the same as normal values. We advocate postauricular neurovascular pedicle island flap for conchal and periconchal areas of anterior surface of the external ear because it matches the skin color, thickness and texture; scars are well hidden, and there is no donor site morbidity. Moreover, it has a constant and reliable neurovascular pedicle.

Combined intraoral and nasal approach to Tessier No:0 cleft with bifid nose.

The surgical correction of craniofacial clefts is an extremely difficult field in pediatric plastic surgery. Facial clefts are rare entities that most plastic surgeons will rarely have to manage. Various surgical techniques devised by some authors for facial clefts have not still widely accepted. The bifid nose deformity is generally an indicator of Tessier No:0 clefts, with various degrees of skeletal problems. The nasal roof area is an important key point in determining the appropriate surgical technique for reconstruction. In this report, a case of Tessier No:0 with a moderate nasal bifidity and ours novel surgical repair technique combining oral and nasal incision are presented.

A new skin flap design for the repair of proximal phalanx base defects in flexion contractures of adjacent fingers.

A random-pattern cutaneous flap with its base at the highly vascularized dorsal web space has been designed to decrease donor site deformity and to increase securely flap mobilization in contractures involving more than 1 adjacent proximal phalanx base. Rectangular flaps facing each other on the lateral sides of adjacent fingers have been raised on a single pedicle in the second, third, or fourth web space. The anatomic integrity of the web space was maintained and exposure of the metacarpophalangeal joints was avoided. Flap donor sites were reconstructed with full-thickness skin grafts. Since September 2000, 22 flaps were raised during a single-stage operation in 13 patients with an average age of 11 years at the time of surgery, and a total of 38 fingers have been reconstructed. The follow-up period averaged 24 months. The postoperative course was uneventful for all patients; all the flaps survived and the donor sites healed without complications. This flap, with its wide arc of rotation and minimal donor site morbidity, is easy to perform and is a good alternative in the reconstruction of multiple proximal phalanx base region flexion contractures of adjacent second, third, fourth, or fifth fingers.

Use of distally pedicled sural fasciocutaneous cross-leg flap in severe foot and ankle trauma: a safe alternative to microsurgery in very young children.

Advances in reconstructive microsurgery have enabled us to make use of many flap alternatives in severe lower-extremity trauma, and traditional cross-leg flaps for wound coverage have been replaced in most centers by free-tissue transfers. But free-flap surgery is still a challenging area in very young pediatric populations because of technical difficulties with considerable drawbacks. Six children with severe foot and ankle trauma were presented. Distally based sural fasciocutaneous cross-leg flaps were carried out to cover the defects, with no complications. Because of its easy dissection and reliable pedicle without compromising the major vessels, this procedure may be a safe choice among the other cross-leg flap alternatives when microsurgery is not considered.

Use of adhesives in cleft palate surgery: a new flap fixation technique.

N-Butyl-2-cyanoacrylate (NB2C) is a synthetic tissue adhesive, and it has been used in many surgical procedures. This study was aimed at evaluating its efficacy in cleft palate repairs. Fifteen patients with soft palate and hard palate clefts had clefts repaired with the use of this synthetic adhesive. The ages at repair ranged from 11 months to 17 years, with an average of 2.4 years. Follow-up time ranged from 14 months to 24 months. No complications were found. The advantages of using NB2C were shorter operative time, more pushback gained, better hemostasis, early and well-tolerated feeding, tension-free closure, and better patient comfort. This study shows NB2C as a useful adjunctive material for affixing the mucoperiosteal flaps to the hard palate.

Two-plane injection of botulinum exotoxin A in glabellar frown lines.

Botulinum exotoxin A has been used for the treatment of glabellar frown lines. Despite this fact, the effect of the toxin is sometimes either partial or lost in a short time. The muscles responsible for frowning, the corrugator supercilii and depressor supercilii muscles, are attached to the periosteum in the glabellar region under the frontalis muscle deep in the medial aspect. The muscles then course laterally and superficially to insert in the skin superior to the eyebrows. Thus, to get a long-lasting and full effect, the exotoxin has been applied deeply in the medial aspect and superficially in the lateral aspect of the glabellar region. It is concluded that botulinum exotoxin is more effective when it is applied in two planes superficially and deep so that the anatomic course of the corrugator supercilii and the depressor supercilii muscles are followed.
