Effects of Comorbidities on the Inferior Pedicle Reduction Mammaplasty: A Statistical Analysis.

BACKGROUND: Multiple studies have analyzed the impact of comorbidities on breast reduction surgery with mixed results. The purpose of this investigation was to perform a statistical analysis of all complications by a single surgeon, using a single technique for breast reduction. METHODS: Records of patients undergoing breast reduction from 1984 to 2019 with an inferior pedicle were reviewed. Comorbidities analyzed included hypertension, diabetes, nicotine use, weight of breast tissue resected, pedicle length, and basal metabolic index. The literature on the effects of comorbidities on outcomes for breast reconstruction was also reviewed. RESULTS: Although increasing body mass index significantly increased the rate of fat necrosis, it did not impact those patients requiring reoperation for this complication. Body mass index greater than 35 kg/m 2 , weight of tissue resection greater than 1000 g, and nipple-to-inframammary fold distance greater than 20 cm all increased the odds ratio of having a breast with some fat necrosis. Increasing body mass index increased the risk of wound healing problems (both major and minor), but not for patients requiring reoperation. Body mass index greater than 35 kg/m 2 , breast tissue resection greater than 1000 g, and nipple-to-inframammary fold distance greater than 20 cm only minimally increased the odds ratio for a major wound complication. CONCLUSIONS: Patients with increased body mass index are at greater risk for fat necrosis and wound healing complications. However, these usually can be managed conservatively in patients undergoing inferior pedicle breast reduction. Patients do not require free nipple grafting. The use of nicotine or the presence of diabetes or hypertension does not impact outcome. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

The Utility of the 5-Factor Modified Frailty Index to Predict Postoperative Risk in Microsurgical Reconstruction.

BACKGROUND: Microsurgical reconstruction is an integral part of plastic surgery. The 5-factor modified frailty index (5-mFI) is an effective tool to predict postoperative complications across multiple subspecialties. We aimed to determine if frailty scores using the 5-mFI can predict postoperative complications specifically in microvascular reconstruction. STUDY DESIGN: Frailty scores were retrospectively assessed in microsurgical reconstruction patients (2012-2016) using the American College of Surgeons National Quality Improvement Program base. The 5 variables that comprise the 5-mFI are history of chronic obstructive pulmonary disease, history of congestive heart failure, functional status, hypertension requiring medication and diabetes. The data were analyzed using the Goodman test, χ2 test, and a logistic regression model. The congruence was also compared between the 5-mFI and the American Society of Anesthesiology (ASA) classification in predicting complications. RESULTS: Of 5894 patients, the highest 5-mFI value was "3." Analyses show an increase in postoperative complications requiring ICU care. Further models indicate an association between readmission with hypertension and chronic obstructive pulmonary disease (P < 0.05). There was an increased risk of a failure to wean from ventilator with a history of chronic obstructive pulmonary disease and diabetes and an increased risk of readmission with a history of hypertension and chronic obstructive pulmonary disease. The 5-mFI and ASA were incongruent in predicting postoperative complications. CONCLUSIONS: The 5-mFI predicts postoperative complications in the microsurgical reconstruction population. Although the 5-mFI and ASA predict different complications, their use provides insight into the potential adjustable risks before surgery.

Palmar Creases and Their Implication on Carpal Tunnel Surgery.

BACKGROUND: A thorough knowledge of normal and variant anatomy of the wrist and hand is fundamental to avoiding complications during carpal tunnel release. The purpose of this study was to document variations of the surface anatomy of the hand to identify a safe zone in which the initial carpal tunnel incision could be placed. The safe zone was identified as the distance between the radial side of hook of hamate and the ulnar edge of the origin of the motor branch of the median nerve (MBMN). METHODS: Kaplan's cardinal line and other superficial markers were used to estimate the size of the safe zone, in accordance to prior published anatomical studies. The presence of a longitudinal palmar crease (thenar, median, or ulnar creases) within the safe zone was recorded. RESULTS: Of the 150 participants (75 male, 75 female) examined, the average safe zone widths were 10.85 (right) and 10.28 (left) mm. In all the hands examined, 86.33% of the safe zones (259 of 300) contained a longitudinal palmar crease. In the White population (n = 50), the average safe zone widths were 11.49 (right) and 10.01 (left) mm; in the African American population (n = 50), the average safe zone widths were 12.27 (right) and 12.01 (left) mm; and in the Asian population (n = 50), the average safe zone widths were 8.79 (right) and 8.82 (left) mm. On overage, males had a larger safe zone width than females by 4.55 mm. CONCLUSIONS: Although there seems to be variability between race and sex with regard to safe zone width, finding 86.33% of longitudinal palmar creases within the safe zone suggests that, for most patients, the initial carpal tunnel surgery incision may be hidden within the palmar crease while minimizing the risk of motor branch of the median nerve injury. Overall, the safe zone width is on average up to 10.5 mm measured from the hook of the hamate along Kaplan's cardinal line.

The Role of Maximal Locoregional Block in Autologous Breast Reconstruction.

BACKGROUND: Enhanced Recovery After Surgery (ERAS) has become the standard of care in microsurgical breast reconstruction. The current literature provides overwhelming evidence of the benefit of ERAS pathways in improving quality of recovery, decreasing length of hospital stay, and minimizing the amount of postoperative narcotic use in these patients. However, there are limited data on the role of using maximal locoregional anesthetic blocks targeting both the abdomen and chest as an integral part of an ERAS protocol in abdominally based autologous breast reconstruction. The aim of this study is to compare the outcomes of implementing a comprehensive ERAS protocol with and without maximal locoregional nerve blocks to determine any added benefit of these blocks to the standard ERAS pathway. METHODS: Forty consecutive patients who underwent abdominally based autologous breast reconstruction in the period between July 2017 and February 2020 were included in this retrospective institutional review board-approved study. The goal was to compare patients who received combined abdominal and thoracic wall locoregional blocks as part of their ERAS pathway (study group) with those who had only transversus abdominis plane blocks. The primary end points were total hospital length of stay, overall opioids consumption, and overall postoperative complications. RESULTS: The use of supplemental thoracic wall block resulted in a shorter hospital length of stay in the study group of 3.2 days compared with 4.2 days for the control group (P < 0.01). Postoperative total morphine equivalent consumption was lower at 38 mg in the study group compared with 51 mg in the control group (P < 0.01). Complications occurred in 6 cases (15%) in the control group versus one minor complication in the thoracic block group. There was no difference between the 2 groups in demographics, comorbidities, and type of reconstruction. CONCLUSION: The maximal locoregional nerve block including a complete chest wall block confers added benefits to the standard ERAS protocol in microvascular breast reconstruction.

An oral presentation of dermatofibromasarcoma protuberans with literature review: A case report.

INTRODUCTION: Dermatofibrosarcoma protuberans (DFSP) is an uncommon, locally invasive soft tissue tumor with a high rate of recurrence after surgical intervention. DFSP primarily occurs on the trunk and proximal extremities, with reported 10-15% occurring in the head and neck region. DFSP presenting within the oral cavity is a rare entity with few descriptions in the literature. Standard of care involves resection, either by Mohs micrographic surgery or wide local excision with careful evaluation of the surgical margins. Due to the invasive nature of this tumor, complete excision in sensitive areas such as the head and neck pose unique challenges. CASE PRESENTATION: We present a case of DFSP presenting from within the oral cavity, along with its management, in a 50-year-old male. In addition, we review the published literature. The patient neglected a 3-month history of a rapidly enlarging mass of the left cheek. A buccal mucosal biopsy revealed the diagnosis of DFSP. The patient underwent wide local excision of the tumor resulting in a full thickness defect which required reconstruction utilizing a radial forearm free flap. The final pathology report demonstrated positive margins that necessitated additional excision. DISCUSSION: There are few reported cases of an intraoral presentation of dermatofibrosarcoma. Due to the sensitive location of the tumor, there are challenges associated with obtaining clear margins after resection and ultimately reconstruction. CONCLUSION: This case and literature review highlight the rarity of an oral cavity presentation DFSP, and the associated surgical challenges.

Sternotomy Wound Closure: Equivalent Results with Less Surgery.

BACKGROUND: Mediastinitis after a median sternotomy can be life-threatening. The advent of pedicle flap-based treatment has resulted in an improvement in both morbidity and mortality. However, significant morbidities can still occur following the use of flaps for sternal closure, particularly in patients with comorbidities. To minimize an extensive surgical dissection, we modified our approach to reconstruction using a modified subpectoral approach, leaving the overlying skin attached. This technique focuses primarily on controlling wound tension rather than on maximal muscle coverage. This study is a retrospective review of 58 consecutive patients treated with this approach, by a single surgeon. METHODS: Fifty-eight consecutive patients treated between 2008 and 2019 were included. All patients received the same procedure regardless of the degree of illness, the extent of tissue loss, and the size of sternal defect. Treatment included thorough debridement, with total sternectomy (if required); limited dissection of the pectoralis major muscle off the chest wall to the level of the pectoralis minor without skin and subcutaneous undermining; no release of the insertion of the pectoralis or use of the rectus abdominis; and midline closure over drains connected to wall suction to obliterate dead space. RESULTS: Reoperations were required in 7 patients (12%). Of these, only 4 (6.9%) were related to continued sternal osteomyelitis. The other reoperations were for hematoma evacuation, breast fat necrosis, and skin necrosis. There were no operative mortalities. CONCLUSION: Chest closure using minimal dissection and tension release is safe, efficient, and associated with a complication rate equivalent to more extensive procedures reported in the literature despite significant comorbidities.

Wise Pattern Direct Implant Breast Reconstruction: A Review and Improved Outcomes Using Dermal Matrix.

BACKGROUND: The inverted T (Wise pattern) mastectomy for patients with macromastia or significant breast ptosis has evolved along with generalized techniques for breast reconstruction. We present a review of Wise pattern breast reconstruction along with our technique for direct to implant reconstruction using dermal matrix. METHODS: The literature was reviewed and an analysis of techniques and complications was performed. We present our series of patients incorporating dermal matrix and relatively large implants in direct to implant reconstruction. RESULTS: Of 18 breasts reconstructed only 2 failed. One caused by flap necrosis secondary to smoking and one as a result of preoperative radiation. CONCLUSION: Wise pattern breast reconstruction using relatively large implants and dermal matrix in direct to implant reconstruction is a safe technique in selected patients with macromastia.

Correction of complete thoracic duct obstruction with lymphovenous bypass: A case report.

Thoracic duct injury can be a devastating injury with disruption of lymphatic flow leading to potentially chylothorax and/or severe lymphedema. Standard treatment modalities include thoracic duct ligation or embolization for chylothorax, but treatment options to date are few for resultant lymphedema. In this case report, we describe lymphaticovenous bypass of the thoracic duct to the jugular venous system in a 21-year-old male with secondary lymphedema after iatrogenic thoracic duct injury. The patient experienced improvement of lymphedema symptoms including decreased weight and limb girth as well as normalization of serum markers indicating improved lymphatic delivery to the venous system. Lymphangiogram at 3 months post op demonstrated patency of the lymphaticovenous anastomoses. At 6-month follow-up, the patient had returned to his preoperative level of activity and showed continued improvement of his lymphedema symptoms. Lymphovenous bypass of the thoracic duct may be an effective technique to treat secondary lymphedema from thoracic duct obstruction, though further studies are required to determine long-term efficacy.

Social Media and the Plastic Surgery Patient.

BACKGROUND: Many plastic surgeons use social media as a marketing tool to attract and retain patients, but information about how patients use social media and their preferred types of plastic surgery posts have been lacking. METHODS: To investigate patients' preferred social media networks and the type of posts they wished to see, a cross-sectional study was conducted in a single aesthetic practice of two plastic surgeons by surveying 100 consecutive patients. RESULTS: The age of the patients averaged 44.4 years (range, 17 to 78 years). Facebook had the greatest patient use and engagement, with YouTube second in use, and Instagram second in number of engaged users. Over half used Pinterest, but with little daily engagement. Only one-fourth used Snapchat, but the percentage of users who were highly engaged was second only to Facebook. The least popular network was Twitter, with the fewest patient users and least engagement. Social media played a minor role compared with the practice's Web site in both influencing patients to choose the practice and providing information on the day of the appointment. Patients most wanted to see posts on a plastic surgeon's social media platform related to practice information, before-and-after photographs, and contests. Articles about plastic surgery held the least interest. Among five types of Web site content, patients expressed most interest in before-and-after photographs. CONCLUSIONS: This study is the first to articulate the plastic surgery patient perspective regarding social media. The findings aim to help plastic surgeons maximize their influence on their target audience.

Impact of Injury Mechanisms on Patterns and Management of Facial Fractures.

Mechanisms causing facial fractures have evolved over time and may be predictive of the types of injuries sustained. The objective of this study is to examine the impact of mechanisms of injury on the type and management of facial fractures at our Level 1 Trauma Center. The authors performed an Institutional Review Board-approved review of our network's trauma registry from 2006 to 2010, documenting age, sex, mechanism, Injury Severity Score, Glasgow Coma Scale, facial fracture patterns (nasal, maxillary/malar, orbital, mandible), and reconstructions. Mechanism rates were compared using a Pearson χ2 test. The database identified 23,318 patients, including 1686 patients with facial fractures and a subset of 1505 patients sustaining 2094 fractures by motor vehicle collision (MVC), fall, or assault. Nasal fractures were the most common injuries sustained by all mechanisms. MVCs were most likely to cause nasal and malar/maxillary fractures (P < 0.01). Falls were the least likely and assaults the most likely to cause mandible fractures (P < 0.001), the most common injury leading to surgical intervention (P < 0.001). Although not statistically significant, fractures sustained in MVCs were the most likely overall to undergo surgical intervention. Age, number of fractures, and alcohol level were statistically significant variables associated with operative management. Age and number of fractures sustained were associated with operative intervention. Although there is a statistically significant correlation between mechanism of injury and type of facial fracture sustained, none of the mechanisms evaluated herein are statistically associated with surgical intervention. Clinical Question/Level of Evidence: Therapeutic, III.

Is there a simple, definitive, and cost-effective way to diagnose osteomyelitis in the pressure ulcer patient?

BACKGROUND: Despite advances in managing pressure ulcers, there is still no definitive way to diagnose bone infection (osteomyelitis) short of open biopsy. An effective, less invasive diagnostic method might result in cost savings and improved care; however, needle aspiration, computed tomography scan, magnetic resonance imaging, ultrasound, and bone scans have proven unsatisfactory in predicting osteomyelitis. The authors reviewed preoperative radiologic studies of stage IV pressure ulcer patients and their bone biopsy results to determine which radiologic studies are most diagnostic for osteomyelitis. METHODS: Patients (n = 44) having surgical débridement of stage IV ulcers with open bone biopsy after prior radiographic imaging (plain films, ultrasound, computed tomography, magnetic resonance imaging, and/or nuclear bone scans) were included. Studies were interpreted by a single musculoskeletal radiologist blinded to information from the medical record and following standard radiologic criteria for the diagnosis of osteomyelitis. RESULTS: The percentage of patients with biopsy-proven osteomyelitis identified with imaging was 50 percent using a computed tomography scan and 88 percent using a plain film of the bony area of involvement. The overall sensitivity of either radiologic study was 61 percent. The percentage of patients without osteomyelitis identified as not having the condition by imaging was 85 percent for the computed tomography scan and 32 percent for the plain film. Overall specificity of both studies was 69 percent. CONCLUSION: Preoperative radiologic studies for osteomyelitis in a pressure ulcer are far from definitive; however, if a radiologic study is used to make that diagnosis in a stage IV pressure ulcer, it would appear that a plain film would suffice.

Prognostic significance of microalbuminuria in postdiarrheal hemolytic uremic syndrome.

Patients who survive the acute phase of postdiarrheal hemolytic uremic syndrome (D+ HUS) may develop renal complications after years of apparent recovery. The optimal regimen for monitoring these children is unclear. We therefore determined if screening for microalbuminuria, in the absence of overt proteinuria at follow-up, increased the sensitivity for predicting long-term renal-related sequelae. We found that screening for microalbuminurea, within the first 6-18 months following an episode of HUS, increased the sensitivity for predicting later sequelae from 22 to 66.7%, compared to screening for overt proteinuria alone. These findings, if confirmed by a larger cohort with more years of follow-up, may facilitate early initiation of intervention strategies designed to reduce progressive renal damage.
