Rigid External Le Fort I Distraction Followed by Secondary Bone Grafting for Maxillary Advancements in Patients With Cleft Lip and Palate.

INTRODUCTION: Maxillary hypoplasia after cleft lip and palate (CLP) repair can result in significant functional and aesthetic impairments. Le Fort I osteotomy & advancement and Le Fort I distraction osteogenesis are standard treatment options for individuals with CLP-associated midface retrusion. However, both of these modalities continue to be associated with a high relapse rate. This study describes surgical outcomes of a 2-stage technique utilizing distraction osteogenesis combined with bone grafting and rigid fixation, which may optimize skeletal stability by reducing relapse. METHODS: A retrospective review of CLP patients with severe maxillary hypoplasia evaluated by a single surgeon from 2003 to 2014 was performed. Twenty-one subjects were identified that underwent maxillary advancement via a 2-stage technique: (1) Le Fort I external rigid distraction using a HALO device, followed by (2) autologous iliac crest bone graft application and plate-fixation. Post-operative cephalograms were taken on average 1-year following surgery. RESULTS: Twelve subjects met the inclusion/exclusion criteria. A distraction rate of 1 mm/day was achieved with an average of 14 mm of maxillary advancement. Average increase in SNA was +9.03°, with an increase from 71.84° to 80.88° (normal = 82.0°, P value <0.0001), with no significant change in SNB, and a +9.63° change in ANB from -7.76° to 1.88° (normal = 1.6°, P value <0.0001). CONCLUSIONS: The described 2-step procedure had similar cephalometric improvements as compared to distraction osteogenesis alone. However, successive bone grafting and rigid fixation as a second procedure may help ameliorate relapse risk and optimize the correction of maxillary hypoplasia in susceptible populations.

Is Article Methodological Quality Associated With Conflicts of Interest?: An Analysis of the Plastic Surgery Literature.

PURPOSE: Conflicts of interest (COI) are an emerging area of discussion within the field of plastic surgery. Recently, several reports have found that research studies that disclose COI are associated with publication of positive outcomes. We hypothesize that this association is driven by higher-quality studies receiving industry funding. This study aimed to investigate the association between industry support and study methodological quality. METHODS: We reviewed all entries in Plastic and Reconstructive Surgery, Annals of Plastic Surgery, and Journal of Plastic, Reconstructive, and Aesthetic Surgery within a 1-year period encompassing 2013. All clinical research articles were analyzed. Studies were evaluated blindly for methodology quality based on a validated scoring system. An ordinal logistic regression model was used to examine the association between methodology score and COI. RESULTS: A total of 1474 articles were reviewed, of which 483 met our inclusion criteria. These articles underwent methodological quality scoring. Conflicts of interest were reported in 28 (5.8%) of these articles. After adjusting for article characteristics in the ordinal logistic regression analysis, there was no significant association between articles with COI and higher methodological scores (P = 0.7636). CONCLUSIONS: Plastic surgery studies that disclose COI are not associated with higher methodological quality when compared with studies that do not disclose COI. These findings suggest that although the presence of COI is associated with positive findings, the association is not shown to be driven by higher-quality studies.

The Impact of Financial Conflicts of Interest in Plastic Surgery: Are They All Created Equal?

BACKGROUND: Recently, several studies have demonstrated that articles that disclose conflicts of interests (COI) are associated with publication of positive results. The purpose of this study was to learn more about the different types of COI as they relate to the general topic of COI in plastic surgery. Specifically, we aimed to examine whether different types of COI are more likely than others to be associated with the presentation of positive findings. METHODS: We reviewed all original articles in Annals of Plastic Surgery, Journal of Plastic, Reconstructive, and Aesthetic Surgery, and Plastic & Reconstructive Surgery from January 1, 2012, to December 31, 2013. All scientific articles were analyzed, and several article characteristics were extracted. Disclosed COI were categorized into the following categories: consultant/employee, royalties/stock options, and research support. The findings reported in each article abstract were blindly graded as reporting a positive, negative, neutral, or not applicable result. A multivariable analysis was performed to determine whether an association existed between certain types of COI and publication of positive conclusions. RESULTS: A total of 3124 articles were identified of which 1185 fulfilled the inclusion criteria. Financial COI were reported in 153 studies (12.9%). The most common type of COI was "research support" (7.3%), whereas the least common was "royalties/stock options" (1.2%). Rates of different types of COI varied significantly by plastic surgery subspecialty field (P < 0.001). In the multivariable analysis, authors who disclosed COI related to research support, consultant/employee, and royalties/stock options were 1.31, 6.62, and 8.72 times more likely, respectively, to publish positive findings when compared with authors that disclosed no COI after correcting for potential confounding factors. However, consultancy/employee status was the only COI category statistically associated with publication of positive results (P < 0.001). CONCLUSIONS: Self-reported COI are uncommon in plastic surgery research. Our results provide evidence that certain types of financial COI are more likely than others to be associated with the presentation of positive findings. This analysis suggests that certain investigators may be more biased, consciously or unconsciously, by the type of financial benefit offered by industry.

Chest Wall Reconstruction: Evolution Over a Decade and Experience With a Novel Technique for Complex Defects.

BACKGROUND: Chest wall reconstruction (CWR) with biologic matrices has gained popularity over the last decade; however, data on this topic remain sparse. The aim of this study is to review the different methods and materials used for CWR while reviewing and highlighting a novel approach using a biologic inlay and synthetic onlay technique for larger, complex high-risk defects. METHODS: A retrospective review was performed of all patients who underwent full thickness chest wall resection and reconstruction during a 10-year period. Patient characteristics, comorbidities, operative data, as well as postoperative wound complications and outcomes were reviewed. Different reconstructive methods and materials were reviewed and compared. RESULTS: From December 2003 to January 2014, a total of 81 patients underwent CWR. The indications for resection/reconstruction included oncologic in 49 patients (60.5%), desmoids tumors in 10 (12.3%), bronchopleural fistula in 3 (3.7%), infection in 7 (8.6%), and anatomic deformity in 7 (8.6%) patients. Synthetic and/or acellular dermal matrices (ADM) reconstruction was used in 59 patients (10 biologic, 22 synthetic, and 27 biologic ADM inlay/synthetic onlay combination). On average, 2.5, 3.5, and 3.6 ribs were resected in the biologic, synthetic, and combination group, respectively (P = 0.1). A greater number of patients in the combination group had a history of chemotherapy and/or radiation therapy (P = 0.03) than the synthetic or biologic alone groups. Risk analysis demonstrated an association between the number of ribs resected and postoperative chest wall complications. The incidence of chest wall/wound complications in the synthetic, combination, and biologic groups was 31.8%, 22.2%, and 10%, respectively (P = 0.47). CONCLUSIONS: In the largest single institution study comparing the use of different reconstructive materials, including ADM in CWR, the authors demonstrate that a biologic inlay/synthetic onlay may be used effectively for high-risk, large complex defects. Early outcomes with this technique are promising. The authors believe this combination highlights benefits from both materials because the ADM facilitates tissue ingrowth and revascularization, whereas the synthetic component provides structural durability. Additional studies with larger sample sizes are necessary to further explore the benefits of the combination technique to determine if outcomes are better than either material alone when used to reconstruct high-risk wounds after larger resections.

Intraoperative Use of Vasopressors Is Safe in Head and Neck Free Tissue Transfer.

BACKGROUND: The purpose of this study is to identify whether intraoperative use of vasoactive medications increases the risk of free flap failure or complications through a systematic review and meta-analysis. MATERIALS AND METHODS: PubMed/MEDLINE, EMBASE, and Scopus databases were searched for studies published through January 2015. English publications that met the following criteria were included: (1) adult patients undergoing head and neck free flap reconstruction; (2) comparison of patients with and without intraoperative vasopressor administration; and (3) documentation of flap failure rate and/or flap complications. The primary outcome was the incidence of flap failure. The secondary outcome was the incidence of overall flap complications. Meta-analysis was performed to obtain pooled odds ratios (ORs) of the effect of intraoperative use of vasopressors on flap failure and complication rates. RESULTS: Four cohort studies met inclusion criteria. All studies were of high methodological quality with an average Methodological Index for Non-Randomized Studies score of 18.75 (range 16-23). A total of 933 patients undergoing head and neck free flap reconstruction were included. Meta-analysis demonstrated no statistically significant difference in the incidence of flap failure (2.9 vs. 3.6%; OR, 0.68; 95% confidence interval [CI], 0.23-1.99; p = 0.48) or incidence of flap complications (16.8 vs. 18.6%; OR, 0.92; 95% CI, 0.60-1.42; p = 0.71). CONCLUSION: Based on the current evidence, intraoperative use of vasopressors has no impact on the incidence of flap failure or flap complications.

Current Trends and Emerging Future of Indocyanine Green Usage in Surgery and Oncology: An Update.

BACKGROUND: Indocyanine green (ICG) is a widely available dye of clinical importance that has been used for more than 50 years. Near-infrared (NIR) ICG fluorescence imaging has found a niche in cancer care since 2005, and was reviewed in 2011. There is a need for a comprehensive update and we aim to provide this through a review of the most recent literature. METHODS: A systematic review of the literature using PubMed, EMBASE, and MEDLINE databases of articles published from 2000 to June 2015 evaluated topics pertinent to NIR fluorescence imaging with ICG in the diagnosis and surgical treatment of cancer. Articles previously referenced in a 2011 review and a 2015 meta-analysis were excluded, while articles that referenced future directions and economics were included in this current review. RESULTS: Since 2011, the literature has grown exponentially, with significant advances at the molecular level. Significant findings from 89 select articles and 10 reviews, most of which were published between 2011 and 2015, are summarized. Preclinical studies are currently underway investigating tumor-specific fluorescence and targeted therapeutic delivery. The potential for ICG exists at every level of cancer care, from diagnosis to surveillance. CONCLUSION: The indications, applications, and potential for ICG have grown exponentially in the past decade; an updated review of the literature is overdue and we present the most comprehensive review to date.

Five-level cervical corpectomy for neurofibromatosis-associated spinal deformity: case report.

PURPOSE: To describe a successful five-level cervical corpectomy and circumferential reconstruction in a patient with a plexiform neurofibroma causing a severe kyphotic deformity. METHODS: Case report. RESULTS: 43-year-old man with history of Neurofibromatosis presented with signs and symptoms of myelopathy with spastic lower extremities and gait difficulties. Imaging studies demonstrated a severe kyphotic deformity of the cervical spine with associated cord compression secondary to an anteriorly positioned plexiform neurofibroma. Two-stage surgical procedure was designed to treat this lesion. Stage I consisted of tracheostomy placement, transmandibular, circumglossal approach to the anterior cervical spine, C2-C6 corpectomies, and C1-C7 reconstruction with a custom titanium cage/plate. Stage II consisted of suboccipital craniectomy, C1-C2 laminectomies, and occipital-cervical thoracic instrumented fusion (O-T8). There were no operative complications, but the patient did develop a small pulmonary embolism post-operatively treated with anticoagulation. Patient required two-weeks of inpatient rehabilitation following surgery. Gastrostomy tube and tracheostomy were successfully discontinued with preserved swallowing and respiratory function. Patient-reported outcome measurements revealed significant and sustained improvement post-operatively. CONCLUSIONS: Five-level cervical corpectomy including C2 can be safely and successfully performed via a transmandibular, circumglossal approach. Circumferential reconstruction utilizing a custom anterior titanium cage and plate system manufactured from a pre-operative CT scan was utilized in this case. Long segment occipital-cervical-thoracic reconstruction is recommended in such a case. Using such a technique, improvement in myelopathy, correction of deformity, and improved quality of life can be achieved.

Application of the Mandible Injury Severity Score to Pediatric Mandibular Fractures.

PURPOSE: The Mandible Injury Severity Score (MISS) has been used to evaluate adult mandibular fractures. The purpose of this study was to evaluate the MISS in a cohort of pediatric patients. PATIENTS AND METHODS: This was a retrospective study of pediatric patients treated for mandibular fractures over a 20-year period. Patients were included if they had computed tomographic imaging available for review and had at least 1 post-treatment visit. The primary predictor variable was the MISS. Secondary predictors were demographic and injury-associated factors. The outcome was treatment-associated complications. Descriptive, bivariate, and multiple logistic regression statistics were computed. RESULTS: One hundred sixteen patients with mandibular fractures were identified; 73 (62.9%) met the inclusion criteria. The sample's mean age was 8.5 ± 4.1 years; 44% were girls. Motor vehicle collisions (60%) and falls (15.1%) were the most common mechanisms. More than 50% of patients had an extra-mandibular injury. The mean MISS was 13.5 ± 7.8. Forty-five percent of the sample underwent open reduction and internal fixation. Complications were noted in 20.5% of patients, of which malocclusion was the most common (8.2%). Increasing MISS was associated with complications (P < .001). After controlling for the effects of age, mechanism, cervical spine and skull base injuries, and treatment, patients with an MISS of at least 14 were significantly more likely to have a complication (odds ratio = 4.0; 95% confidence interval, 1.05-15.0; P = .04). CONCLUSIONS: In pediatric patients with mandibular fractures, increased severity of injury is associated with complications, even after controlling for the effects of multiple confounders, including open treatment.

The Role of Postoperative Antibiotics in Mandible Fractures: A Systematic Review of the Literature.

INTRODUCTION: Little debate exists regarding the use of preoperative and perioperative antibiotic prophylaxis in the setting of mandibular fracture management; however, employing postoperative prophylactic antibiotics remains an inexact science based on experience rather than evidence. In this systematic review, the authors evaluate scientific literature and report results of an international survey that provide information regarding current practices of the plastic surgery community. METHODS: Systematic literature review was performed using Medline, Embase, PubMed, and Cochrane databases to identify studies evaluating use of antibiotics in patients suffering from mandible fractures. Level 1, 2, and large retrospective studies were included. Case reports were excluded. Additionally, an E-survey was distributed to all ASPS members and data were collected over a 5-month period through SurveyMonkey. RESULTS: Four hundred twenty-seven articles published before December 2012 were identified. Seventy-one articles met inclusion criteria. Five articles remained when exclusion criteria were applied.ASPS member survey demonstrated 13% response rate (687 responses/5299 questionnaires). Of respondents, 75% placed patients (ORIF group) with open mandible fractures on prophylactic antibiotics for up to 3 days (44.1%), 1 week (54.8%), and more than 1 week (1.1%). Of respondents, 51% placed patients (ORIF group) with closed mandible fracture on prophylactic antibiotics for up to 3 days (50.5%), 1 week (48.6%), and more than 1 week (1%). CONCLUSION: Critical literature review demonstrates a trend towards no postoperative antibiotic coverage (>24 hours) in patients undergoing mandibular ORIF. There is further need for prospective, randomized control trials with a standardized regimen. Our survey elucidates the variability of plastic surgeons' clinical practices.

Differential expression of degradome components in cutaneous squamous cell carcinomas.

Although the cure rate for cutaneous squamous cell carcinoma is high, the diverse spectrum of squamous cell carcinoma has made it difficult for early diagnosis, particularly the aggressive tumors that are highly associated with mortality. Therefore, molecular markers are needed as an adjunct to current staging methods for diagnosing high-risk lesions, and stratifying those patients with aggressive tumors. To identify such biomarkers, we have examined a comprehensive set of 200 histologically defined squamous cell carcinoma and normal skin samples by using a combination of microarray, QRT-PCR and immunohistochemistry analyses. A characteristic and distinguishable profile including matrix metalloproteinase (MMP) as well as other degradome components was differentially expressed in squamous cell carcinoma compared with normal skin samples. The expression levels of some of these genes including matrix metallopeptidase 1 (MMP1), matrix metallopeptidase 10 (MMP10), parathyroid hormone-like hormone (PTHLH), cyclin-dependent kinase inhibitor 2A (CDKN2A), A disintegrin and metalloproteinase with thrombospondin motifs 1 (ADAMTS1), FBJ osteosarcoma oncogene (FOS), interleukin 6 (IL6) and reversion-inducing-cysteine-rich protein with kazal motifs (RECK) were significantly differentially expressed (P≤0.02) in squamous cell carcinoma compared with normal skin. Furthermore, based on receiver operating characteristic analyses, the mRNA and protein levels of MMP1 are significantly higher in aggressive tumors compared with non-aggressive tumors. Given that MMPs represent the most prominent family of proteinases associated with tumorigenesis, we believe that they may have an important role in modulating the tumor microenvironment of squamous cell carcinoma.

Head and Neck Malignancies in Children.

Since 2000, the incidence of head and neck cancer has dramatically increased. At this time, future studies are needed to further elucidate the factors contributing to rising incidence of head and neck cancer in children. This article provides a treatment framework for the pediatric surgical oncologist who manages cancer in children.

Survival implications of cervical lymphadenectomy in patients with medullary thyroid cancer.

BACKGROUND: The relationship between extent of cervical lymphadenectomy along with the number of involved lymph nodes (LNs) removed and overall survival has not been well documented in patients with medullary thyroid carcinoma (MTC). This study investigates whether the overall number of LNs removed and the number of metastatic LNs are independent prognostic factors for overall survival. METHODS: Data from patients with MTC in the Surveillance, Epidemiology, and End Results (SEER) registry database were examined. After categorizing the study population based on the number of overall LNs examined and the number of metastatic LNs, survival estimates were compared. The total number of examined LNs and their histopathological status were analyzed for their prognostic value in estimating overall survival. RESULTS: 593 patients were included in this study. Those with all negative LNs had the best overall survival; those with LNs examined and at least one positive LN had worst overall survival (p < 0.0001). The total number of examined LNs for both groups with negative and positive LNs was not associated with improved survival outcome (p = 0.41). In node-positive patients, each additional positive LN was significantly associated with an increase in overall mortality [hazard ratio (HR) = 1.05, 95% confidence interval (CI) = 1.02-1.08]. CONCLUSIONS: Cervical LN metastases conferred an independent risk for worse survival rate in MTC. Cervical lymphadenectomy is important for staging and regional disease control, however the extent of lymph node dissection, the overall number of lymph nodes removed along with removal of an increased number of involved lymph nodes do not confer a survival advantage. Future prospective studies are needed.

A new American Joint Committee on Cancer staging system for cutaneous squamous cell carcinoma: creation and rationale for inclusion of tumor (T) characteristics.

BACKGROUND: The incidence of cutaneous squamous cell carcinoma (cSCC) is increasing. Although most patients achieve complete remission with surgical treatment, those with advanced disease have a poor prognosis. The American Joint Committee on Cancer (AJCC) is responsible for the staging criteria for all cancers. For the past 20 years, the AJCC cancer staging manual has grouped all nonmelanoma skin cancers, including cSCC, together for the purposes of staging. However, based on new evidence, the AJCC has determined that cSCC should have a separate staging system in the 7th edition AJCC staging manual. OBJECTIVE: We sought to present the rationale for and characteristics of the new AJCC staging system specific to cSCC tumor characteristics (T). METHODS: The Nonmelanoma Skin Cancer Task Force of AJCC reviewed relevant data and reached expert consensus in creating the 7th edition AJCC staging system for cSCC. Emphasis was placed on prospectively accumulated data and multivariate analyses. Concordance with head and neck cancer staging system was also achieved. RESULTS: A new AJCC cSCC T classification is presented. The T classification is determined by tumor diameter, invasion into cranial bone, and high-risk features, including anatomic location, tumor thickness and level, differentiation, and perineural invasion. LIMITATIONS: The data available for analysis are still suboptimal, with limited prospective outcomes trials and few multivariate analyses. CONCLUSIONS: The new AJCC staging system for cSCC incorporates tumor-specific (T) staging features and will encourage coordinated, consistent collection of data that will be the basis of improved prognostic systems in the future.

Closed reduction of laterally displaced fracture/dislocation of the mandibular condylar process in a child.

This is a unique case of isolated lateral fracture/dislocation of the condylar process in a 3-year-old child injured on an escalator. Immediate closed reduction under general anesthesia successfully restored condylar height and premorbid dental occlusion. Maxillomandibular fixation was not used because mandibular mobilization was encouraged. Clinical follow-up confirmed maintenance of normal dental occlusion and temporomandibular joint function.

Extirpative Considerations of Melanoma of the Head and Neck.

The incidence of melanoma is continuing to rise in the United States, and head and neck melanomas account for 25% of all cutaneous melanomas. The National Comprehensive Cancer Network guideline recommendations for surgical margins and sentinel lymph node biopsy in head and neck melanomas are the same as cutaneous melanoma located in other regions, but require special considerations when performing wide local excision, sentinel lymph node biopsy, and completion lymph node dissection and reconstruction taking into account the location of the melanoma and structures involved in and around the suggested margins.

Combined Pipeline Embolization Device with Endoscopic Endonasal Fascia Lata/Muscle Graft Repair as a Salvage Technique for Treatment of Iatrogenic Carotid Artery Pseudoaneurysm.

The incidence of internal carotid artery (ICA) injury associated with endoscopic endonasal approaches to the pituitary is less than 1%. While parent vessel sacrifice has historically been the choice of treatment, vessel-preserving endovascular techniques have been reported. Although flow diversion offers endoluminal reconstruction, its major limitation is the delay in obtaining complete occlusion. We describe the use of a combined Pipeline embolization device (PED) with endoscopic endonasal repair using a fascia lata/muscle graft to treat an iatrogenic ICA pseudoaneurysm and report long-term radiographic follow-up. Further investigation into the utility of directed endoscopic endonasal repair of iatrogenic pseudoaneurysms initially treated with PED is necessary, especially given the need of post-PED anticoagulation and the rate of permanent neurological deficit after ICA sacrifice.

Familial isolated primary hyperparathyroidism with double adenoma.

Familial hyperparathyroidism includes the diagnoses of multiple endocrine neoplasia type 1, type 2A, and familial isolated primary hyperparathyroidism. Familial isolated primary hyperparathyroidism is a rare, distinct form of familial primary hyperparathyroidism, mainly due to four-gland hyperplasia or single-gland adenoma. We describe our success in treating a 24-year-old woman with familial isolated primary hyperparathyroidism with resection of double adenoma, using the guide of intraoperative parathyroid hormone (PTH) monitoring. Familial isolated primary hyperparathyroidism usually presents with four-gland hyperplasia or single-gland adenoma. However, double adenoma should be considered in the differential diagnosis. Using intraoperative parathyroid hormone levels and minimal-access surgery in familial isolated primary hyperparathyroidism may be promising.

Pioneers in Modern Craniofacial Surgery: Assessing the Academic Impact of Drs. Joseph Gruss and Paul Manson.

BACKGROUND: The authors conducted this study to assess the impact that Drs. Joseph Gruss and Paul Manson have had on craniofacial surgery through their individual contributions and through their trainees. METHODS: This was a retrospective analysis of fellows trained by either Dr. Gruss or Dr. Manson. Demographic and bibliometric measures were recorded for each fellow. Demographic factors included years since completion of fellowship training, current practice of craniomaxillofacial surgery, academic practice, and academic leadership roles. Bibliometric measures included number of publications, number of citations, and h-index. To adjust for scholarly activity before fellowship training, only contributions published after fellowship training were included. RESULTS: Over a 39-year period, a total of 86 surgeons completed fellowship training with either of the two principal surgeons. The mean time since completion of training was 18.7 ± 11.4 years. Seventy-nine percent of surgeons had active practices in craniomaxillofacial surgery; 54 percent had academic practices. The mean number of publications was 26.4 ± 69.3, the mean number of citations was 582 ± 2406, and the average h-index was 6.7 ± 10.6. Among academic surgeons, the average h-index was 10.7 ± 13.1, 89 percent practiced in North America, 89 percent had active practices in craniomaxillofacial surgery, and nearly 50 percent had achieved a leadership role. CONCLUSIONS: Modern craniofacial reconstruction has evolved from principles used in trauma and correction of congenital differences. The extensive impact that Drs. Paul Manson and Joseph Gruss have had on the field, and plastic surgery at large, is evident through their primary contributions and the immense impact their trainees have had on the field.
