Background: Fractures of the facial skeleton are relatively uncommon in children and adolescents, and only a few reports review a significant number of patients. The authors performed a retrospective study to analyze the different characteristics of such fractures in the pediatric population of Portugal. Methods: The authors reviewed the clinical records of a series of 912 patients 18 years of age or younger with facial fractures treated by the Departments of Plastic, Reconstructive, and Aesthetic Surgery and of Maxillofacial Surgery, São João Hospital, in Porto, Portugal, between the years 1993 and 2002. The following parameters were evaluated: age; sex; cause of accident; hour, day, and month of hospital admission; location and type of fractures; presence and location of associated injuries; treatment methods; length of in-hospital stay; and complications. Results: A total of 1251 fractures were treated. The ratio of boys to girls was 3.1:1. Patients between 16 and 18 years old were the major group (47.8 percent). Motor vehicle accident was the most common cause of injury (53.3 percent of patients). Mandibular fracture was the most common type of fracture (48.8 percent). Associated injuries occurred in 558 patients (64.5 percent). Conclusions: Pediatric facial fractures are usually associated with severe trauma. The number of fractures caused by automobile accidents has decreased (p < 0.05). The incidence of this type of fracture is high in Portugal.

Fournier's gangrene is a rare and potentially fatal infectious disease characterized by necrotic fasciitis of the perineum and abdominal wall, along with the scrotum and penis in men and the vulva in women. Fournier's gangrene is a true surgical emergency. Skin loss can be very incapacitating and difficult to repair. The authors reviewed retrospectively the clinical records of a series of 43 patients with Fournier's gangrene between the years 1985 and 2003 who, after initial treatment by the Departments of Urology and Surgery, were referred to the Department of Plastic Surgery for reconstruction. The following parameters were evaluated: age, gender, interval between onset of symptoms and diagnosis, clinical symptoms, lesion site, results of bacteriologic cultures, cause and predisposing factors, treatment and reconstructive procedures, length of hospital stay, and outcome. The mean patient age was 56.6 years. Fifteen patients (34.9 percent) had diabetes mellitus. The cause of Fournier's gangrene was found in 32 patients (74.4 percent). The most common presentation was scrotal swelling, and scrotal involvement was found in 40 cases (93.0 percent). All of the patients underwent surgical debridement, and several reconstruction techniques were used. The mean length of hospital stay was 73.6 days. Two patients died. Management of this infectious entity should be aggressive. Several techniques that are used to reconstruct the lost tissue have shown good results. The superomedial thigh skin flap has proven to be a reliable method of resurfacing large scrotal defects. Reconstructive surgery makes the return to a normal social life possible in many cases.

Silicone gel breast implants are associated with long-term adverse events, including capsular contracture, with reported incidence rates as high as 50 percent. However, it is not clear how long the follow-up period should be and whether there is any association with estrogen or menopausal status. In addition, the placement of Baker grade II subjects in the majority of reports has been in data sets of controls instead of capsular contracture. A retrospective medical study (1998 to 2004) was performed in women (n = 157) who received textured silicone breast implants for aesthetic or reconstructive procedures at the Hospital of S. João (Portugal). Medical data were collected that included the following: patient demographics, history, lifestyle factors, surgical procedures, and postoperative complications. Statistical analyses included Pearson chi-square testing, logistic regression modeling, and chi-squared automatic interaction detection (CHAID) methods. The reconstructive cohort had a great incidence of capsular contracture compared with the cosmetic cohort. If one considered no capsular contracture versus capsular contracture, the follow-up period should be longer than 42 months. However, if considering no capsular contracture and grade II subjects versus grade III or IV subjects, a longer follow-up period of 64 months was determined. There was no association between capsular contracture and menopause/estrogen status. Increased frequencies of capsular contracture were recorded in breast reconstruction that were not attributable to estrogen or menopausal status. On the basis of these results, the authors propose a follow-up period longer than 42 months and the inclusion of Baker grade II subjects.

Scarpa fascia preservation has been suggested as a way of reducing complications associated with conventional abdominoplasty. A prospective randomized study was conducted to evaluate the effect on results and complications of preserving the Scarpa fascia during a full abdominoplasty. This was a single-center study conducted from August of 2009 to February of 2011. Patients were assigned randomly to one of two procedures: classic full abdominoplasty (group A) or a similar type of abdominoplasty except for the preservation of the Scarpa fascia and the deep fat compartment in the infraumbilical area (group B). Four surgeons were involved in the study. Several variables were determined: general characteristics, time to suction drain removal, total volume of drain output, length of hospital stay, systemic complications, local complications, and aesthetic result. A total of 160 full abdominoplasties were performed in women (group A, 80 patients; group B, 80 patients) equally divided by the four involved surgeons. There were no statistically significant differences between groups with respect to general characteristics, complications (except for the seroma rate), and aesthetic result. The Scarpa fascia preservation group had a highly significant reduction of 65.5 percent on the total drain output, 3 days on the time to drain removal, and 86.7 percent on the seroma rate. Preservation of the Scarpa fascia during an abdominoplasty had a beneficial effect on patient recovery, as it reduced the total drain output, time to drain removal, and seroma rate without compromising the aesthetic result.

Preservation of the Scarpa fascia has been suggested as a way of lowering complications associated with conventional abdominoplasty. Objective evidence regarding this strategy is lacking. The purpose of this investigation was to evaluate the effect of preserving the Scarpa fascia in the infraumbilical area during a full abdominoplasty. A prospective study was performed at a single center from November of 2005 to November of 2007 of the patients submitted to abdominoplasty with umbilical transposition. Two groups were identified: group A, classic full abdominoplasty; and group B, full abdominoplasty with preservation of infraumbilical Scarpa fascia. Several variables were determined: age, body mass index, previous surgical procedures, comorbid conditions, specimen weight, time to suction drain removal, total volume of drain output, and length of hospital stay. A total of 208 full abdominoplasties were performed (group A, 143 patients; group B, 65 patients). There was no statistically significant difference between groups with respect to body mass index, previous abdominal operations, comorbid medical conditions, or weight of the surgical specimen (p > 0.05). The group with preservation of the Scarpa fascia had an average reduction of the total amount of drain output of more than 50 percent (p < 0001). This group also had an average reduction of 2.0 days until the time to drain removal (p < 0.001) and 1.9 days of the hospital stay (p < 0.001). Preservation of the Scarpa fascia during abdominoplasty has a beneficial effect on patient recovery, as it reduces the total drain output, time to drain removal, and length of hospital stay.
