Excised abdominoplasty material as a systematic plastic surgical training model.

Achieving a level of technical skill and confidence in surgical operations is the main goal of plastic surgical training. Operating rooms were accepted as the practical teaching venues of the traditional apprenticeship model. However, increased patient population, time, and ethical and legal considerations made preoperation room practical work a must for plastic surgical training. There are several plastic surgical teaching models and simulators which are very useful in preoperation room practical training and the evaluation of plastic surgery residents. The full thickness skin with its vascular network excised in abdominoplasty procedures is an easily obtainable real human tissue which could be used as a training model in plastic surgery.

Treatment of a congenital melanocytic nevus on the forehead with immediate tissue expansion technique: a three-year follow-up.

The aim of this case report was to determine the method and basic principles of immediate tissue expansion using a Foley catheter in the forehead region for treating a medium-sized congenital melanocytic nevus. A 4-year-old child presented with a supraorbitally located forehead congenital melanocytic nevus, close to the midline. Total excision and reconstruction with intraoperatively expanded forehead skin below the hairline was performed. Intraoperative tissue expansion using a Foley catheter allowed us to obtain expanded and enhanced local tissue, which had tissue characteristics similar to those of the forehead skin, and thus closure of a medium-sized defect without distorting important anatomic structures such as the brow and frontal hairline was possible. Of the two methods of tissue expansion, immediate expansion using a Foley catheter is a good alternative in single-stage reconstruction of head and neck defects because it has the advantage of omnidirectional expansion.

Clinical experience with a reverse-flow anterolateral thigh perforator flap for the reconstruction of soft-tissue defects of the knee and proximal lower leg.

BACKGROUND: Soft-tissue defects in the knee region are usually complex and require adequate reconstruction with flaps. The aim of this article is to present the authors' experience using the reverse-flow anterolateral thigh perforator flap for the reconstruction of a variety of soft-tissue defects around the knee including the upper third of the leg. METHODS: A total of 17 reverse-flow anterolateral thigh perforator flaps were used for reconstruction of soft-tissue defects around the knee and the upper third of the leg between December 2006 and December 2010. The ages of patients ranged from 26 to 82 years (mean, 64.3). Defect sizes ranged from 6×8 to 10×14 cm. The application of the reverse-flow anterolateral thigh perforator flaps in relation to the variable arterial anatomy was described. RESULTS: The dimensions of the largest flap used for reconstruction were 10×16 cm. The perforators were musculocutaneous in 14 patients and septocutaneous in three patients. The maximal pedicle length was 28 cm. All of the flaps survived. Only two flaps developed partial skin necrosis at the distal end. Good aesthetic and functional results with adequate range of motion were achieved in all cases. CONCLUSION: Despite a variable vascular anatomy that can be challenging for the surgeon, reverse-flow anterolateral thigh perforator flap is a safe and reliable method for reconstruction of the defects around the knee and even the upper third of the leg.

Effects of reduction mammoplasty on metabolic profile and body weight.

BACKGROUND: Advanced studies on adipose tissue have established that subcutaneous adipose tissue acts as an endocrine organ to help maintain homeostasis. Based on this information, many plastic surgeons have evaluated the metabolic effects of liposuction because liposuction is the most common surgical procedure in plastic surgery. Liposuction removes a substantial amount of subcutaneous fat from a specific area of the body. Mammoplasty is another procedure that removes a large amount of subcutaneous fat. In this study, the metabolic effects of reduction mammoplasty were evaluated with hemogram, blood glucose, lipid profile, insulin, and insulin resistance tests before and after surgery. METHODS: The study involved 35 patients who underwent reduction mammoplasty between January 2006 and June 2009. All the patients were evaluated with physical examination and their history, height, and weight were obtained. Venous blood samples were collected before, 4 h after, and 3 months after the surgical procedure to evaluate hemogram, blood glucose, insulin, and lipid profiles. The HOMA scores of the patients were calculated. Inferiorly based dermal pedicle, central pedicle, and free nipple graft techniques were used in the operations and all excision materials were sent for histopathological examination. RESULTS: The mean age of the patients was 39.6 ± 11.6 years. The mean excision volume was 2249 ± 1001 g. Body mass indexes were not significantly different before and 3 months after the surgery (p > 0.05). Blood glucose, LDL, HDL, triglyceride, total cholesterol, hemoglobin, and hematocrit values before and 4 h after the surgery were also different (p < 0.05). However, comparisons with the 3-month postoperative test results revealed no statistically significant differences (p > 0.05) and comparisons of all the measurements showed that insulin levels and HOMA scores were not significantly different (p > 0.05). CONCLUSION: The results of the present study showed that reduction mammoplasty operations do not have any positive effects on blood insulin, glucose profile, lipid profile, and body mass index 3 months after the surgery.

An unusual auricular malformation accompanied by accessory tragus: macrotragus.

Definition of malformations of the tragus is important for terminology and treatment. Most common entities are the skin tag, accessory tragus, preauricular sinus, and cyst, whereas macrotragus is an uncommon and unaddressed deformity that should be distinguished from these. In this report, three cases with diagnosis of the macrotragus are presented. The tragus was uniformly large and displaced anteriorly, and external auditory meatus was not obliterated in all cases. For correction, excision of the excess tragal cartilage and skin was performed. In all cases, bilaterally symmetric tragus was achieved. There were no complications in the early postoperative period and there was no enlargement after 6months of observation. Macrotragus and accessory tragus are different entities that should be distinguished for accurate diagnosis. They have similar histopathological but distinct anatomical characteristics. Although both are treated by a simple excision, in the case of macrotragus, special effort should be taken to leave enough cartilage to restore normal tragal contours.

A lingual osteoid mass originating from hyaline cartilage.

BACKGROUND: Lingual osseous and chondromatous growths are rare but well-defined entities. The cause of these growths is still unknown, but several theories have been proposed. CASE PRESENTATION: A mass measuring one cm in diameter on the dorsum of the tongue in a 28-year-old male causing discomfort was found to consist predominantly of hyaline cartilage with prominent bone transformation. CONCLUSION: This finding confirms that bony masses in the tongue may originate from cartilaginous precursors, in contrast to similar masses seen on the face which are (often) purely osseous.

Bilobed flap reconstruction in infraorbital skin defects.

BACKGROUND: The infraorbital region is an important subunit for facial aesthetics. Improper closure of skin defects involving this region may lead to deformity in the lower lid and to ectropion. This report presents the authors' experience with 15 patients who had infraorbital skin defects reconstructed with the bilobed flap from the zygomatic and lateral cheek regions. METHODS: Most of the operations were performed under local anesthesia. Pathologic diagnoses included basal cell carcinoma, squamous cell carcinoma, melanoma, and hemangioma. Although we cannot deny that bilobed flaps used in this series were not random flaps, we would like to emphasize that when a flap with a bilobed design is chosen for reconstruction of an infraorbital defect, a superiorly based bilobed flap should be selected to avoid ectropion or any distortion in the middle face. As an adjunct procedure, a glabellar flap was used in some patients who had defects extending medially as well. RESULTS: The results of the repair were satisfactory with respect to color match, texture, and functional properties. CONCLUSION: The superiorly based bilobed flap should be always kept in mind when planning a local flap in the infraorbital region.

Island rat groin flaps with twisted pedicles.

Clinical attempts are made to avoid rotating a flap and twisting the pedicle for fear of perfusion compromise. Torsion of an island rat groin flap pedicle is not a well-recognized experimental entity. The authors describe the results of island flap rotation with pedicle twisting in the rat groin flap model. Forty male Wistar rats were randomly divided into four groups of 10 animals each. In each group, bilateral groin flaps were elevated; one flap was sutured in place without rotation and the contralateral flap was subjected to 180, 270, 360, or 720 degrees of rotation. Blood flow within the flaps was assessed by laser Doppler flowmetry, and flap edema and necrosis were determined 10 days postoperatively. No differences were noted between control flaps and those subjected to 180 and 270 degrees of rotation. Although flaps subjected to 360 degrees of rotation demonstrated a large amount of postoperative edema and congestion of the subcutaneous tissue with some histologic changes, all flaps in this group survived. Measured flap weights at death were different from those of controls. All flaps subjected to 720 degrees of rotation underwent ischemic necrosis. Because of the differences between human skin architecture and rat skin architecture it cannot be concluded that similar results would be observed in any human skin flap. There might be three important points arising from this study of unknowingly twisted island groin flap pedicles in the rat model: (1) twisting of less than 360 degrees has no effect on flap survival; (2) twisting of 720 degrees is always associated with skin flap necrosis; (3) twisting of 360 degrees, although associated with some changes, does not cause skin flap necrosis.

Reappraisal of island modifications of lateral calcaneal artery skin flap.

Reconstruction of soft-tissue defects of the calcaneal region and the heel is very demanding and necessitates, as a rule, a sensate and thin flap. The ideal characteristics of a sensate and thin layer of flap should be combined with a reliable blood supply and minimal morbidity at the donor site. The authors report an updated review of their experience with the use of island modifications of the lateral calcaneal artery skin flap-the lateral calcaneal island flap, the lateral calcaneal V-Y advancement flap, and the bilobed-shaped lateral calcaneal island advancement flap-for the reconstruction of small and medium-sized tissue defects over the exposed calcaneal tendons and calcaneal bones of 18 patients. All of the procedures were performed under spinal or epidural anesthesia. There were no problems associated with flap viability, but the authors have seen necrosis of undermined skin between the lateral malleolus and calcaneal tendon in two cases and a partial loss of skin graft in one case. In this article, the authors discuss some advantages and disadvantages of the use of a lateral calcaneal island flap and its modifications.

Hatchet-shaped tensor fascia lata musculocutaneous flap for the coverage of trochanteric pressure sores: a new modification.

The tensor fascia lata flap is one of the appropriate choices for the coverage of trochanteric pressure sores. The authors designed a new, hatched-shaped tensor fascia lata musculocutaneous flap with distal Z-plasty closure and applied it to four trochanteric defects in 4 patients. Satisfactory results were obtained in all patients. The hatchet-shaped tensor fascia lata musculocutaneous flap is very safe, reliable, and practical. Designing the flap in a hatchet shape allows one to use the proximal and well-vascularized portion of the flap in the trochanteric pressure sore area. Another important advantage is the possibility of reuse resulting from recurrence. Prevention of a "dog-ear" deformity at the recipient site provides a smooth contour on the lateral aspect of the thigh. Another advantage is the tension-free Z-plasty closure of the donor site without need of grafting.
