Use of previously divided latissimus dorsi muscle for bronchopleural fistula.

Management of postpneumonectomy bronchopleural fistula remains a major challenge for thoracic surgeons. Successful closure of a postpneumonectomy bronchopleural fistula was performed in a 60-year-old man, using a flap made by a combination of serratus anterior and latissimus dorsi muscle which had been divided during the pneumonectomy operation. The flap was prepared on the presence of a dependable collateral serratus anterior branch to the lateral thoracic artery, which provides retrograde flow to the latissimus dorsi muscle.

New end-to-end microvascular anastomosis with geometrically adaptable ends technique: an experimental study on rats.

Objective: The aim of this study was to develop an effective arterial anastomosis model with a high patency rate and low operation time. We introduced a new end-to-end microvascular anastomosis with geometrically adaptable ends.

Methodology: In this technique, two triangular flaps were prepared at the end of the vessels and four stitches applied on the tip of those flaps.

Effects of polyglycolic acid bioabsorbable membrane and oxidised cellulose on the osteogenesis in bone defects: an experimental study.

Background: The purpose of the present study was to determine the effects of polyglycolic acid bioabsorbable membrane and oxidised cellulose on the osteogenesis in bone defects.

Materials And Methods: Fifty-four male adult New Zealand White rabbits weighing 3.0 to 3.

Viability of diced, crushed cartilage grafts and the effects of Surgicel (oxidized regenerated cellulose) on cartilage grafts.

The viability of cartilage grafts has been well documented; however, controversy still exists about the viability of crushed cartilage. Recently, there has been a tendency to use diced cartilage grafts wrapped with oxidized regenerated cellulose (Surgicel) sheets for improving dorsal contour in rhinoplasty. The viability of diced cartilage grafts and the effect of Surgicel on cartilage grafts are not well known.

The fate of neurotization techniques on reinnervation after denervation of the gastrocnemius muscle: an experimental study.

In nerve injuries, if it is not possible to reinnervate muscle by using neurorrhaphy and nerve grafting technique, reinnervation should be provided by the use of neuroization-directly implanting motor nerve into muscle. A comparative study of three techniques of neurotization is presented in rabbits. In this experimental study, a total of 40 white New Zealand rabbits were used and divided into four groups, each including 10 rabbits.

Exposure of high-density porous polyethylene (Medpor) used for contour restoration and treatment.

Porous high-density polyethylene (Medpor) is a biocompatible large-pore, high-density polyethylene implant. It is well tolerated by surrounding tissue, and its porous structure is rapidly infiltrated by host tissue. It is a highly stable and somewhat flexible porous alloplast that has rapid tissue ingrowth into its pores.

Tissue engineering of high density porous polyethylene implant for three-dimensional reconstruction: an experimental study.

Three-dimensional defects have been reconstructed with carved and remodelled frameworks wrapped within vascular carriers. If sufficient vascular penetration can be established without any change in the size and shape of an implant, it will be possible to cover it with a skin graft and aesthetically important fine details can be obtained. To achieve this, we first prefabricated high-density porous polyethylene implant in rabbits.

Island V-Y tensor fasciae latae fasciocutaneous flap for coverage of trochanteric pressure sores.

The distal fasciocutaneous portion of the lateral thigh is supplied by the direct cutaneous branch of the lateral descending branch of the lateral circumflex femoral artery and the third perforating artery of the deep femoral artery. This consistent vascular anatomy allows raising a distal skin island based on both arteries on the lateral thigh, and this flap can be advanced into a trochanteric defect according to the V-Y technique. Based on anatomic and clinical study, a new design has been developed of the tensor fasciae latae fasciocutaneous flap, which is supplied by two pedicles.

The effects of L-arginine and iloprost on the viability of random skin flaps in rats.

The effects of an intravenous infusion of L-arginine as a physiological precursor of endothelium-derived relaxing factor/nitric oxide (EDRF/NO), iloprost (a stable prostacyclin (PGI2) analogue), and L-arginine combined with iloprost on skin viability were studied in 9 x 3 cm random pattern skin flaps in rats. Intravenous infusion of all drugs was started at the beginning of the operation and continued for 60 minutes. At the end of infusion period the depth of fluorescein dye penetration in the skin flap was assessed visually from photographic records, and the flap survival area was measured by the grid method at the seventh postoperative day.

Vaginal reconstruction with free jejunal flap.

Congenital absence of a vagina is a rare but outstanding anomaly of plastic surgery. Although many methods are described for reconstruction of vaginal agenesis, there is not a method yet to be approved as a perfect solution to this problem. With the aim of solving the problems faced with conventional methods, free jejunal transplantation was planned to construct a neovagina.

Pilomatrixoma of the earlobe.

Background: Pilomatrixoma most commonly occurs in the head and neck region, appearing primarily in the first two decades of life. The lesion is described as a tumor with differentiation toward hair cells and surgical excision is the treatment of choice.

Objective: We report an uncommon localization of a perforating type pilomatrixoma of 5 x 4 x 4 cm in size that developed from the earlobe.

Prefabricated microvascular shoulder free flap for forehead reconstruction.

In a case with a large forehead defect following tight scalp bandaging in childhood, a prefabricated microvascular shoulder free flap was used for reconstruction. A free forearm fascial flap, with the radial artery and the concomitant vein as pedicle, was harvested and inserted under a subcutaneous pocket opened in the left shoulder region which served as the future "prefabricated free flap". In addition, a tissue expander was placed in this pocket to provide the necessary tissue expansion to enable primary donor site closure.

Applications of free scapular flap.

The scapular flap described by Saijo and dos Santos, presents some advantages such as a thin and hairless flap, large vessel diameters, and a long vascular pedicle with a constant anatomy. Furthermore, it provides combined use of skin and vascularized bone tissue from the scapula. Between the years 1988 and 1991, we have successfully used free scapular flaps for the reconstruction of various defects in twelve patients.

Hemimandibular reconstruction with bipedicled scapular osteocutaneous free flap.

A case report is presented on the successful use of a bipedicled scapular osteocutaneous free flap in a young woman, whose hemimandible was resected because of sarcoma, 1 year prior to presentation. The postoperative course was uneventful and donor site morbidity minimal.

Effects of free perichondrial graft replacement of epiphyseal cartilage on bone growth.

An experimental study in 24 lambs was carried out to find an alternative tissue for the distal epiphyseal cartilage of the femur. The animals were divided into three groups. In the first group (n = 12) the left femoral distal epiphyseal cartilage was completely removed and replaced by a free perichondrial graft taken from the distal half of the scapula.

A new surgical approach in genital lymphedema.

A new surgical approach has been used in a case of genital lymphedema. After resection of the lymphedematous mass, U-shaped flaps were made from the suprapubic region anteriorly and the posterior scrotal skin posteriorly. The denuded penis was transposed to its original place by passing it through a buttonhole incision made on the anterior flap.

The cartilaginous potential of the perichondrium in rabbit ear and rib. A comparative study in vivo and in vitro.

In an experimental study the cartilaginous protential of the rabbit ear perichondrium has been compared with that of the rib in vivo and in vitro. Perichondrium was transferred as free autologous grafts to the subcutaneous tissue on the scalp and as loose bodies into the knee joint. The presence of cartilage in the grafts was examined after six weeks.
