摘要:

Several technical details of secondary nose correction in unilateral cleft lip procedure are presented. A new technique of total removal of distorted septal cartilage is described, correcting it under full vision and replanting it afterwards into the nose, thus clearing both airways and reshaping the nose profile at the same time. Also different cartilage-mucosal flaps are described as a way to create symmetry in the nasal tip region and both ala nasi.

摘要:

Four pairs of identical female twins have undergone a variety of plastic surgery procedures, including rhinoplasties, rhytidectomies, augmentation mammaplasties, and trochanteric liposuction.Performing plastic surgery on identical twins implies special considerations: the extent of preoperative phenotypic identity, the behavior of each twin (dominant or recessive), the twins' personal interdependence and individual expectations, the operative strategy (simultaneous versus sequential operations), the eventual complications, and the extent to which the operative results and postoperative appearance are identical.In general, counseling, operative technique, and responsibility for producing good results place greater demands on surgeons when performing plastic surgery on identical twins than on singletons. Still, the results have been gratifying.

摘要:

Soft tissue defects of the dorsal side of the elbow require a stable soft tissue reconstruction. Therefore, for the treatment of limited, uninfected defects, local or distant skin flaps should be used.For large and infected defects, the use of the proximally pedicled arteria radialis forearm flap is indicated. We used the flap in 14 patients as an alternative to conventional methods. This neurovascular, septocutaneous flap proved safe and versatile, guaranteeing stable soft tissue reconstruction of the dorsal aspect of the elbow.The flap has an orthograde flow and is nourished by the radial artery. With its long, neurovascular pedicle, it can be transposed in a proximal ulnar or radial direction.Four years after operation, all elbow joints showed a complete range of motion. No further soft tissue instabilities were seen.

摘要:

Cranio-orbital facial scoliosis is the result of unilateral premature stenosis of the craniofacial skeleton. Plagiocephaly is only a subform of the syndrome. The deformity progresses unless operative treatment is given. Operative treatment is indicated for functional, aesthetic, and psychosocial reasons. We advocate early operation in infancy (3 to 6 months) consisting of wide resection of the stenosed sutures of the cranium and orbit, repositioning, and remodeling relying on the spontaneous autodynamic reshaping of the nasoethmoidal complex and the midface structures during the course of further growth. In adolescents and adults, multisegmental osteotomies and remodeling into a definitive position are necessary.

摘要:

Problems in treating burn sequelae include scar tissue contraction, which may develop after wound infections, after secondary wound healing by granulations, and also after split-skin transplants. Development of scar cords near or even over joints can ultimately lead to deformities of the body and limbs because of restriction of mobility. Compression bandages have the goal of counteracting these problems, but are not always effective.An attempt must be made to resect the scar cords and to cover the defect with skin transplants or to change the line of the scar cord with Z plasties. However, the altered blood flow in the nodularly twisted collagen fiber structure of the hypertrophic scar frequently causes the tips of transposed skin flaps (as, for example, in Z plasties) to become necrotic. This situation is avoided by application of Y-V plasties, in which the skin for transposition is not detached from its substratum (in contrast to the Z plasty) but is displaced by sliding it on its substratum. For this purpose, the tension of the scar cord is eliminated over the entire length by several transverse Y-shaped incisions situated in parallel. If the tongues of the upper part slide into the stem of the Y and finally form a V, the scar cord can be lengthened without raising the dermis from its substratum and endangering its blood flow. Because of good results, Y-V plasty has entirely replaced Z plasty in the correction of contracted burn scars at my hospital.

摘要:

In search of a biocompatible implant for the collection of small deficiencies within the dermal corium as in wrinkles and acne scars, polymethylmethacrylate (PMMA) microspheres, 10 to 63 µm in diameter, were dispersed in Tween 80 medium and injected intradermally and subdermally into the abdominal skin of rats. Histological examination of specimens for up to 7 months revealed a modest tissue reaction, forming a delicate fibrous capsule around each individual microsphere within 4 months. Foreign body giant cells were seen rarely (in up to 1.5% of all cells). No breakdown, corrosion, or phagocytosis of the spheres was observed at 7 months. The Tween 80 dispersion medium did not produce any histologically detectable reaction.Because PMMA products (Paladon, Palacos) have been used in medicine for almost 50 years without causing biological degradation or cancer, the material may be applied safely in the form of microspheres (Arteplast) in corium and subcutis of human patients with wrinkles or acne scars.

摘要:

Two annoying problems are encountered in surgical correction of greater defects by flap plasty: the widely undermined cavity seen when using transposition flaps to cover large wound cavities and the necessity to cut away healthy skin because of dog ears or a Burow's triangle. The V flap is a method of shifting and transposing of the skin surrounding the defect to avoid these troublesome disadvantages. With the exception of cases where a myocutaneous island flap is indicated, this simple V-flap technique yields excellent surgical results.
