Outcome analysis of helmet therapy for positional plagiocephaly using a three-dimensional surface scanning laser.

Introduction: A dramatic rise in positional plagiocephaly has been noted over the last decade. Methods for treating and following outcomes are varied. We present our results from a passive soft helmet molding therapy using a surface scanning laser to provide objective outcomes. Methods: One hundred seventy-five infants with positional plagiocephaly were treated at our institution over a 6-month period. The helmets used were soft foam helmets modified to fit each patient. Results were measured using a three-dimensional surface scanning laser and objective measurements of asymmetry. Compliance was also documented. Results: The scanning laser allowed for objective measurements of symmetry over time and was useful in following outcomes. Improvement in head shape was noted after about 4 months of therapy. Patients who were more compliant with therapy achieved better results. Conclusion: Use of the three-dimensional scanning laser and objective scoring system shows significant improvement in patients who were compliant with helmet therapy.

Aesthetic outcomes of acellular dermal matrix in tissue expander/implant-based breast reconstruction.

IntroductionTissue expander and implant–based breast reconstruction after mastectomy is the most common method of breast reconstruction. Modifications of the traditional total submuscular reconstruction (TSR) have been made using acellular dermal matrix (ADM) to create an inferolateral sling and a more natural implant pocket for superior aesthetic results. The objective of this study was to assess aesthetic outcomes when using ADM in breast reconstruction. MethodsA retrospective chart review identified all patients who underwent implant-based breast reconstruction from 2005 to 2009 at our institution. Demographic information, complications, reoperations, and aesthetic outcome data were collected for all patients meeting inclusion criteria related to adequate follow-up and postoperative photographs. Five aesthetic outcomes were evaluated for all study patients by 18 blinded evaluators using postoperative photographs. Outcomes were scored on a scale of 1 to 5, with 5 representing the best possible aesthetic score. ResultsA total of 122 patients underwent 183 tissue expander–based reconstructions (ADM, n = 58; TSR, n = 125). The infection rate in patients with ADM was 16.2% compared to 5.9% in TSR patients, but this was not statistically significant (P = 0.09). Capsular contracture was more common in TSR patients (23.5%), compared to those with ADM (8.1%), P = 0.048. Aesthetic scores from the attending plastic surgeons were as follows: natural contour (ADM, 3.36; TSR, 3.02; P = 0.0001), symmetry of shape (ADM, 3.57; TSR, 3.27; P = 0.005), symmetry of size (ADM, 3.68; TSR, 3.42; P = 0.002), position on chest wall (ADM, 3.75; TSR, 3.45; P = 0.004), and overall aesthetic appearance (ADM, 3.56; TSR, 3.20; P = 0.0001). ConclusionsFor all 5 aesthetic parameters evaluated, the ADM group scored significantly higher than the TSR group by 18 blinded evaluators. These consistent findings suggest that the use of ADM in breast reconstruction does confer a significant advantage in aesthetic outcomes for breast reconstruction. This is likely at the cost of a higher infection rate when using ADM; however, that may be offset by the advantage of a lower rate of capsular contracture in patients with ADM.

Outcome study of the surgical management of panniculitis.

Patients with panniculus morbidus have an abdominal panniculus that becomes a pathologic entity, associated with the development of candidal intertrigo, dermatitis, lymphedema, and ischemic panniculitis. Panniculectomy is a standard treatment for this problem. The objective of this study was to determine risk factors for complications associated with panniculectomy surgery to lower the complication rate. We performed a retrospective chart review of patients who underwent panniculectomy between 1999 and 2007 by looking at data related to surgical complications, comorbidities, age, and gender. In 563 patients, we recorded the incidence of the following complications: wound-related (infection, dehiscence, and/or necrosis), hematoma/seroma, respiratory distress, blood transfusions, deep venous thrombosis or pulmonary embolism, and death. Overall, 34.3% of patients suffered at least 1 complication. In patients with wound complications specifically, there was a significantly higher body mass index versus those with no wound complications (43.7% vs. 30.7%, P < 0.0001). Smokers also had a higher rate of wound complications (40.5% vs. 19.5%, P < 0.0001).

Evaluating the safety and efficacy of tranexamic acid administration in pediatric cranial vault reconstruction.

BackgroundBlood loss is the leading cause of mortality after major craniofacial surgery. Autologous blood donation, short-term normovolemic hemodilution, and intraoperative blood salvage have shown low efficacy in decreasing transfusions. Tranexamic acid (TXA) is a synthetic antifibrinolytic drug that competitively decreases the conversion of plasminogen to plasmin, thereby suppressing fibrinolysis. The purpose of this study was to investigate the impact that TXA administration has on intraoperative blood loss and blood product transfusion in pediatric patients undergoing cranial vault reconstruction. MethodsAn Internal Review Board-approved retrospective study was conducted on a consecutive series of pediatric patients undergoing cranial vault reconstruction from January 2009 to June 2012. Seventeen consecutive patients who received TXA at the time of cranial vault reconstruction were compared with 20 patients who did not receive TXA. Criteria for blood product transfusion were identical for both groups. Outcomes including perioperative blood loss, volume of blood transfused, and adverse effects were analyzed. ResultsThe TXA group had a significantly lower perioperative blood loss (9.4 versus 21.1 mL/kg, P < 0.0001) and lower volume of perioperative mean blood product transfusion (12.8 versus 31.3 mL/kg, P < 0.0001) compared with the non-TXA group. There was no significant difference in demographic data, infection rate, change in preoperative to postoperative hematocrit, duration of surgery, or complication rates between the TXA and non-TXA groups. No drug-related adverse effects were identified in patients who received TXA. ConclusionsThe use of TXA in pediatric cranial vault reconstruction significantly reduces perioperative blood loss and blood product transfusion requirements. The TXA administration is safe and may improve patient outcomes by decreasing the likelihood of adverse effects related to blood product transfusion.

Outcome analysis of 541 women undergoing breast conservation therapy.

Breast conservation therapy (BCT) has evolved as a favorable approach to the management of early-stage breast cancer. Shortcomings of BCT include the potential need for re-excision in the event of positive tumor margins as well as the untoward sequelae of radiation therapy. Both of those factors have led to a substantial proportion of patients undergoing BCT who ultimately report suboptimal aesthetic outcomes. Application of plastic surgery principles to the management of this patient subset has been shown to be beneficial from both an oncologic and cosmetic perspective. The aim of this study was to identify factors that may predict which patients would benefit most from involvement of a plastic surgeon before BCT. A retrospective analysis was performed on 762 patients undergoing lumpectomy during a 10-year study period at a single institution. Younger women and patients with tumor size approaching 2 cm were noted to have a significantly higher likelihood of oncologic outcomes that ultimately required breast reconstruction. Integration of oncoplastic techniques in the surgical management of patients undergoing BCT would likely contribute to improvement in aesthetic outcomes and overall patient satisfaction.

What's in a Name? Accurately Diagnosing Metopic Craniosynostosis Using a Computational Approach.

Background: The metopic suture is unlike other cranial sutures in that it normally closes in infancy. Consequently, the diagnosis of metopic synostosis depends primarily on a subjective assessment of cranial shape. The purpose of this study was to create a simple, reproducible radiographic method to quantify forehead shape and distinguish trigonocephaly from normal cranial shape variation. Methods: Computed tomography scans were acquired for 92 control patients (mean age, 4.2 ± 3.3 months) and 18 patients (mean age, 6.2 ± 3.3 months) with a diagnosis of metopic synostosis. A statistical model of the normal cranial shape was constructed, and deformation fields were calculated for patients with metopic synostosis. Optimal and divergence (simplified) interfrontal angles (IFA) were defined based on the three points of maximum average deformation on the frontal bones and metopic suture, respectively. Statistical analysis was performed to assess the accuracy and reliability of the diagnostic procedure. Results: The optimal interfrontal angle was found to be significantly different between the synostosis (116.5 ± 5.8 degrees; minimum, 106.8 degrees; maximum, 126.6 degrees) and control (136.7 ± 6.2 degrees; minimum, 123.8 degrees; maximum, 169.3 degrees) groups (p < 0.001). Divergence interfrontal angles were also significantly different between groups. Accuracy, in terms of available clinical diagnosis, for the optimal and divergent angles, was 0.981 and 0.954, respectively. Conclusions: Cranial shape analysis provides an objective and extremely accurate measure by which to diagnose abnormal interfrontal narrowing, the hallmark of metopic synostosis. The simple planar angle measurement proposed is reproducible and accurate, and can eliminate diagnostic subjectivity in this disorder. CLINICAL QUESTION/LEVEL OF EVIDENCE: Diagnostic, IV.

Time-dependent perioperative anesthetic management and outcomes of the first 100 consecutive cases of spring-assisted surgery for sagittal craniosynostosis.

Background:  The anesthetic risks and outcomes of the first 100 consecutive spring‐assisted surgeries (SAS) for cranial expansion from a single institution are reported. The effect of number of procedures was also tested on hematocrit postoperative day 1 (POD1), anesthesia time, and surgery time of the first procedure.

Outcomes of immediate breast reconstruction in patients undergoing single-stage sentinel lymph node biopsy and mastectomy.

The ability to more definitively plan breast reconstruction after obtaining final histologic analysis of the sentinel lymph node biopsy (SLNB) has led several groups to advocate a staged approach to SLNB and mastectomy. Certain disadvantages are inherent in that approach, including increased patient morbidity, financial expense, and inconvenience. A retrospective review was conducted 195 procedures in which mastectomy and SLNB were performed in a single stage with immediate breast reconstruction (IBR) over a 10-year period. Long-term outcomes were analyzed within the context of patient characteristics and SLNB results. Intraoperative SLNB analysis was found to be a reliable method for planning IBR, as there were no patients noted to have untoward sequelae as a result of a false-negative SLNB, and the probability of postmastectomy radiation therapy was predictable based on the intraoperative SLNB results. We advocate that SLNB be performed in a single stage with mastectomy and IBR.

Craniosynostosis Following Fetal Methotrexate Exposure.

AbstractMethotrexate (MTX) is an antimetabolite, folic acid antagonist that inhibits purine nucleotide production, DNA synthesis, and cellular proliferation. Despite widespread therapeutic uses, MTX remains a potent teratogen. Methotrexate embryopathy encompasses multiorgan system dysfunction, including intrauterine growth restriction as well as cardiac, craniofacial, renal, genital, and skeletal abnormalities. Effects of MTX exposure on fetal development continue to be described. This series of 4 patients with MTX-associated craniosynostosis represents the largest published association between prenatal MTX exposure and premature cranial suture closure.

An Unconventional Presentation of Branchio-Oculo-Facial Syndrome.

AbstractBranchio-oculo-facial syndrome (BOFS) is a rare disorder characterized by branchial or pharyngeal arch malformations, ocular findings, and craniofacial anomalies. Activating mutations in the enhancer-binding protein 2 alpha, TFAP2A, gene is responsible for the autosomal-dominant inheritance of BOFS. While documented patients of BOFS report wide variability in phenotype expressivity, patients typically demonstrate cervical or infra-auricular anomalies, diverse ocular malformations including microphthalmia and coloboma, and highly characteristic pseudo-cleft or palate defects. The authors present the case of an infant with an unconventional presentation of BOFS to highlight key distinguishing features of this disorder, and to emphasize the importance of a multidisciplinary approach in the diagnosis and management of these patients.
