Purpose: Classic literature indicates an infrequency of metopic craniosynostosis (3 to 10 percent) compared to other single-suture craniosynostosis. Recent observation challenges these conceptions, warranting long-term demographic analysis. Methods: Syndromic craniofacial dysostoses and multiple suture involvement were exclusion criteria, leaving only single suture synostoses treated between 1975 and 2004. A chart review was performed and patient information recorded. Chi square analysis and Fishers exact were used to determine differences in patient characteristics. A Morans I statistic was used to determine differences in spatial means and whether changes in incidence of single-suture synostoses over time are a function of regional phenomena. Results: Over 800 patients presented to The Childrens Hospital of Philadelphia with a diagnosis of single-suture synostosis. There was an outpacing of sagittal suture involvement over other sutures. Data demonstrate a decrease in unicoronal synostosis and an increase in metopic synostosis (p = 0.011). Geostatistical analysis reveals increasing separation between populations over the study period: 9.8 miles in the first 5 years to 20.8 miles in the last 5 years. Metopic maternal age increased between 1975–1989 and 1990–2004 (p = 0.002, 0.0002), while unicoronal maternal age did not. The proportion of male patients increased considerably in the metopic group compared to unicoronals from 1990–2004 (p = 0.0001), as did the proportion of syndromic metopic patients (p = 0.02). Plausible etiologies for these epidemiological shifts are discussed. Conclusions: Metopic synostosis is on the rise. Changing demographic bases and increasing proportions of syndromic patients may be clues to the etiology of this epidemiologic event.

Cutaneous wound healing is a complex response to skin injury. Deregulation of this process can lead to excessive scar formation, as seen in keloids. Keloids are common skin lesions that are difficult to treat and are associated with high recurrence rates despite the large number of available treatment options. With increased knowledge of the disease process and further scientific advancements, future approaches will hopefully improve keloid treatment. In this article, we review the epidemiology, genetic basis, etiology, clinical features, pathogenesis, and management of keloids.

BACKGROUND The role of acellular dermal matrix (ADM) in abdominal wall reconstruction (AWR) is unclear. The aim of this study was to review the management, complications, and long-term outcomes of AWR using ADM in a large surgical cohort. METHODS Retrospective chart review of patients undergoing AWR using ADM from 2004 to 2007 was performed. Demographic data, comorbidities, complications, and long-term outcomes were collected. RESULTS There were 77 cases in 68 patients with mean age of 61.1 +/- 1.4 years. The most common indication was infected fascia (n = 19 [25%]). Wound closure was achieved in 75% of the cases via primary (n = 26 [45%]), secondary intention (n = 17 [29%]), or skin graft (n = 15 [26%]). Nonprimary closure was achieved in 5.7 +/- .7 months. There were 32 perioperative (39%) and 33 long-term (43%) complications. Over a mean follow-up period of 13.2 +/- 1.5 months, the hernia recurrence rate was 27% (n = 21). CONCLUSION Although ADM is a viable option in AWR, the high hernia recurrence rate warrants a continued search for alternative biologic materials to improve outcomes.

Incisional hernias in the abdominal wall are a by-product of multiple previous laparotomies. Unfortunately, the incidence of incisional hernias has risen, as we have progressed with new surgical techniques in the treatment of abdominal pathologies. Many methods have been attempted in the past to achieve a better and more durable repair, namely using components separation to bring the fascia into the midline, and reinforce incisional hernias with different mesh materials. The authors review the recent literature regarding the efficacy of these synthetic materials and biomaterials in incisional hernia repair, as well as share their experience in treating complex abdominal wall defects using components separation and biologic mesh.

Mandibular trauma is a common problem seen by plastic surgeons. When fractures occur, they have the ability to affect the patients occlusion significantly, cause infection, and lead to considerable pain. Interventions to prevent these sequelae require either closed or open forms of reduction and fixation. Physicians determining how to manage these injuries should take into consideration the nature of the injury, background information regarding the patients health, and the patients comorbidities. Whereas general principles guide the management of the majority of injuries, special consideration must be paid to the edentulous patient, complex and comminuted fractures, and pediatric patients. These topics are discussed in this article, with a special emphasis on pearls of mandibular trauma management.

BACKGROUND Adolescent breast hypertrophy can have long-term negative medical and psychological impacts. In select patients, breast reduction surgery is the best treatment. Unfortunately, many in the general and medical communities hold certain misconceptions regarding the indications and timing of this procedure. Several etiologies of adolescent breast hypertrophy, including juvenile gigantomastia, adolescent macromastia, and obesity-related breast hypertrophy, complicate the issue. It is our hope that this paper will clarify these misconceptions through a combined retrospective and literature review. METHODS A retrospective review was conducted looking at adolescent females (≤18 years old) who had undergone bilateral breast reduction surgery. Their preoperative comorbidities, BMI, reduction volume, postoperative complications, and subjective satisfaction were recorded. In addition, a literature review was completed. RESULTS 34 patients underwent bilateral breast reduction surgery. The average BMI was 29.5 kg/m(2). The average volume resected during bilateral breast reductions was 1820.9 g. Postoperative complications include dehiscence (9%), infection (3%), and poor scarring (6%). There were no cases of recurrence or need for repeat operation. Self-reported patient satisfaction was 97%. All patients described significant improvements in self body-image and participation in social activities. The literature review yielded 25 relevant reported articles, 24 of which are case studies. CONCLUSION Reduction mammaplasty is safe and effective. It is the preferred treatment method for breast hypertrophy in the adolescent female and may be the only way to alleviate the increased social, psychological, and physical strain caused by this condition.

Isolated unilateral lambdoid craniosynostosis is often confused with posterior positional plagiocephaly because of a general overlap in their clinical presentations; however, distinction between these 2 entities is important because of the differences in appropriate management. Historical literature teaches that ear position is posterior in lambdoid synostosis, whereas it is anterior in positional plagiocephaly. Recently, several cases of anterior ear position in isolated unilateral lambdoid synostosis presented to the Texas Childrens Hospital. A review of the cases and literature revealed that there are now 37 cases of unilateral lambdoid synostosis in the literature in which ipsilateral ear position is reported. Twelve cases (32%) had anteriorly displaced ears, 6 cases (16%) were nondisplaced, 7 cases (19%) were displaced posteriorly, 4 cases (11%) anteroinferiorly, 1 case (3%) inferiorly, and 7 cases (19%) posteroinferiorly. Based on this review, it seems that the diagnostic significance of the external ear position is unclear at this point.

Macromastia in adolescents is multifactorial and usually idiopathic, associated with obesity or hormonal imbalances. Less commonly, it can result from virginal or juvenile breast hypertrophy, a rare condition of unknown etiology, where an alarmingly rapid breast enlargement occurs during puberty. Breast hypertrophy in the adolescent population can have significant long-term medical and psychological impacts. Although symptoms can be severe, many plastic surgeons, pediatricians, and parents are often reluctant to surgically treat adolescent macromastia. However, reduction mammoplasty is a safe and effective treatment and may be the only way to alleviate the increased social, psychological, and physical strain caused by macromastia in adolescents.

BACKGROUND Nasal airway obstruction is a frequently-encountered problem, often secondary to inferior turbinate hypertrophy. Medical treatment can be beneficial but is inadequate for many individuals. For these refractory cases, surgical intervention plays a key role in management. OBJECTIVE The authors evaluate the current trends in surgical management of inferior turbinate hypertrophy and review the senior authors (SS) preferred technique. METHODS A questionnaire was devised and sent to members of the American Society for Aesthetic Plastic Surgery (ASAPS) to determine their preferred methods for assessment and treatment of inferior turbinate hypertrophy. RESULTS One hundred and twenty-seven physicians responded to the survey, with 85% of surveys completed fully. Of the responses, 117 (92%) respondents were trained solely in plastic surgery and 108 (86.4%) were in private practice. Roughly 81.6% of respondents employ a clinical exam alone to evaluate for airway issues. The most commonly-preferred techniques to treat inferior turbinate hypertrophy were a limited turbinate excision (61.9%) and turbinate outfracture (35.2%). CONCLUSIONS Based on the results of this study, it appears that limited turbinate excision and turbinate outfracture are the most commonly-used techniques in private practice by plastic surgeons. Newer techniques such as radiofrequency coblation have yet to become prevalent in terms of application, despite their current prevalence within the medical literature. The optimal method of management for inferior turbinate reduction should take into consideration the surgeons skill and preference, access to surgical instruments, mode of anesthesia, and the current literature.

A 29 year old Hispanic woman with a history of breast augmentation and a pregnancy complicated by placental abruption presented to the plastic surgery service for evaluation of a swollen right breast. The patient was examined and several tests were performed to rule out infection, galactocele, and malignancy. The swelling was attributed to fluid adjacent to her implant which was aspirated and found to contain red blood cells and foam cells but no infectious agent or malignant cells. One month after aspiration and continued drainage, the patient returned with recurrent swelling and pain. Repeat imaging showed recurrent fluid collection in the right breast. Excision and capsulectomy were performed and the patient was found to have a double capsule with a seroma. This article presents the first known case of pregnancy-associated late implant seroma formation, as well as a brief review of the literature regarding this rare finding in prosthetic breast augmentation.
