Effect of Platelet-Rich Plasma on Peripheral Nerve Regeneration

Activated platelets release various growth factors, some of which are recognized to improve nerve regeneration. This study evaluated the effect of platelet-rich plasma (PRP) in end-to-end neurorrhaphy. A total of 45 Wistar rats were used, with the initial five used for PRP preparation. The right hind limbs were used as experimental, with the left as control. The animals were treated in five groups. Group A (n = 4): The right sciatic nerve was dissected only from the sciatic notch to the bifurcation. In all other groups, the nerve was sharply transected and repaired with: group B (n = 8): two sutures; group C (n = 8): six sutures; group D (n = 10): two sutures and PRP; and group E (n = 10): six sutures and PRP. Groups D and E were compared with groups B and C, respectively. Group E had a shorter latency time in electromyography ( P < 0.01) and a thicker myelin layer in the histological evaluation ( P < 0.003) in comparison with group C. These positive effects of PRP were not detected in the nerves were repaired with two sutures. In this animal model, the application of PRP to the repair site helped to improve remyelinization of the sciatic nerve in rats when the epineural repair was done with six sutures.

Proper timing of breast reduction during the menstrual cycle.

Breasts are known to show cyclic changes in accordance with the menstrual cycle, and speculations have been made regarding the ideal timing of breast surgery in this extent, but the clinical evidence to support global acceptance and application is lacking. This study was designed to establish the relationship of intraoperative bleeding and postoperative drainage with the menstrual period of 35 reduction mammaplasty patients. The results indicate that both perioperative blood loss and postoperative drainage were significantly reduced when breast reduction is performed during the periovulatory phase compared with the perimenstrual phase. The authors strongly recommend the interval between days 8 and 20 of the menstrual cycle as a more convenient period to perform breast reduction. Drains may be avoided during this period, but they are preferred if the surgery is done during the perimenstrual phase.

Background: Reconstruction of defects around the ankle region has always been challenging for plastic surgeons. Distally based lateral and medial leg adipofascial flaps are among the flaps of choice for coverage of this difficult region. Presented here is the authors’ clinical experience with these flaps, particularly emphasizing the complicated attempts in diabetic patients. Methods: Seven skin defects around the ankle were reconstructed with lateral and medial leg adipofascial flaps. The lowermost perforators of the peroneal or posterior tibial artery were identified preoperatively, and a straight incision through skin only was made proximal to this perforator. With the skin flaps reflected, the adipofascial flap was than raised in the subfascial plane. The perforators to be retained in the base were located and the flap was then turned over to cover the defect, followed by application of a split-thickness skin graft over the flap. The donor site was closed primarily. Results: The ages of the patients ranged from 25 to 80 years, and the size of the flaps ranged from 3 × 5 cm to 7 × 10 cm. Four defects were reconstructed with lateral leg adipofascial flaps, and medial leg adipofascial flaps were used in three. Two flaps healed uneventfully. Partial or total graft loss and partial flap necrosis were observed in five patients, four of whom were diabetic. Conclusions: Leg adipofascial flaps offer a valuable option for repair of defects around the ankle in many cases. However, adipofascial flaps should be used with caution in old, diabetic patients and, when performed, the probability of a second or third procedure should be considered.

Cerebriform fibrous proliferation vs. proteus syndrome.

Proteus syndrome is a rare, congenital hamartomatous syndrome that presents with a wide range of abnormalities. Regardless of different manifestations found in different patients, there exists three mandatory criteria for the diagnosis of this syndrome: a mosaic distribution of the lesions, a progressive course, and sporadic occurrence. When these criteria are met, the presence of additional connective tissue nevi, which are encountered mostly on the plantar surface of the feet, suffices for the diagnosis of Proteus syndrome. The authors present a 48-year-old woman who had been evaluated for a lesion on the plantar aspect of her left foot that was diagnosed as keloid and was treated unsuccessfully. In the light of the literature and with the help of histopathological reevaluation, the authors thought this unique lesion may be a localized form of Proteus syndrome.

Scar tissue graft as a filler for soft tissue augmentation.

Soft tissue augmentation with autogenous tissue has been used to correct various defects during aesthetic facial contouring and reconstructive procedures. Although dermal grafts have longer survival rates, fat grafts always have been more popular because of the simple harvesting and grafting methods used. The authors aimed to use existing scar tissue as an injectable graft and to compare its effectiveness as a soft tissue filler substance with that of dermal grafts. In this study, scar tissue was created on 24 male Wistar rats. The created scar and normal healthy skin were removed from the rat dorsal scapular donor site. After depithelialization, the harvested tissues were minced until they were thin enough to pass through a 16-gauge needle. The grafts then were injected into the recipient site between the abdominal muscles. Volumetric analyses and histologic evaluation of the grafts were performed 1, 3, and 5 months after transplantation. The first month after the injection, the amount of remaining dermis graft was more than the scar graft, and this difference was statistically significant. However, at the end of months 3 and 5, there was no marked difference between the groups. The remaining volume of injected scar tissue graft was comparable with that of the dermis graft. The scar grafts were composed mainly of dense connective tissue during all the evaluation periods. In this study, scar tissue provided results comparable with those of dermal grafts up to 5 months when used as a soft tissue filler. It seems that neovascularization of the scar graft may be inadequate for maintenance of graft viability, as compared with dermis grafts. On the other hand, the scar graft formed fibrous tissue, which may be responsible for providing adequate volume as a filler. This may have clinical implications for the patient who needs both scar revision and soft tissue augmentation procedures simultaneously.

Chest wall deformity after tissue expansion

Yakup Sariguney; Suhan Ayhan; Tolga Eryilmaz

There have been few reports about skeletal changes beneath a tissue expander in breast reconstruction. We present one, and surgeons should be cautious about the possibility of skeletal deformities in patients who are osteoporotic and postmenopausal who require prolonged tissue expansion.
