Does Increased Experience with Tissue Oximetry Monitoring in Microsurgical Breast Reconstruction Lead to Decreased Flap Loss? The Learning Effect.

Background: Early studies have shown that near-infrared monitoring with tissue oximetry shows promise in providing earlier detection of free flap vascular compromise. However, large-scale clinical evaluation of this technology on flap outcome has not previously been established. This study examines the effect of tissue oximetry on flap reexploration rates and salvage over a 10-year period. The learning curve for this new technology is also assessed. Methods: A retrospective review was performed of prospectively maintained data on all microsurgical breast reconstructions performed at an academic institution from 2004 to 2014. Patients were divided into two separate cohorts—standard clinical monitoring and standard clinical monitoring plus tissue oximetry—and rates of reexploration and flap salvage were compared. Subgroup analysis (tertiles) was performed to assess outcomes with increasing experience. Results: A total of 380 flaps (36.2 percent) received standard clinical monitoring, and 670 flaps (63.8 percent) received additional tissue oximetry monitoring. The rate of flap salvage before implementation of tissue oximetry monitoring was 57.7 percent and increased to 96.6 percent (p < 0.001). The number of complete flap losses decreased from 11 (2.9 percent) to one (0.1 percent) with the use of tissue oximetry (p < 0.001). Subgroup analysis demonstrated significantly fewer reexplorations in the third tertile. Conclusions: Inclusion of continuous tissue oximetry in the postoperative monitoring protocol of microsurgical breast reconstruction is associated with significantly improved salvage rates and fewer flap losses. Furthermore, learning curve assessment demonstrates that use of tissue oximetry can decrease the rate of reexploration over time.

A Novel Free Flap Monitoring System Using Tissue Oximetry with Text Message Alerts.

Background The time to detection of vascular compromise is a significant predictor of free flap salvage outcomes as early reexploration improves salvage rates. Continuous transcutaneous near-infrared tissue oximetry is an objective, quantitative method of detecting flap vascular compromise and has been shown to allow earlier reexploration and higher salvage rates than clinical assessment alone. We designed a novel text messaging system to improve communication using tissue oximetry monitoring. Methods A retrospective review was performed of a prospectively collected database of all microsurgical breast reconstructions from 2008 to 2015. A novel text messaging system was introduced in 2013 and programmed to send text messages alert when the tissue oximetry readings suggested potential flap compromise based on established thresholds. Patient demographics and complications, including rate of reexploration and flap loss were assessed. Results There were 900 autologous microsurgical breast free flaps during the study period: 614 were monitored with standard clinical monitoring and tissue oximetry compared with 286 flaps with the additional text messaging system. There were 27 unplanned returns to the operating room in the tissue oximetry group and 5 in the text messaging group with 1 complete flap loss in each group. Reexploration occurred sooner as a result of these text message alerts (17.5 vs. 26.6 hours postoperatively), however, it did not achieve statistical significance. Conclusions We were able to demonstrate the use of a novel text messaging system for tissue oximetry. This alert system shows promise in identifying impending flap loss with rapid notification of the surgical team.

Pneumosinus dilatans: Is it more than an aesthetic concern?

BackgroundPneumosinus dilatans (PD) is a pathologic condition involving the hyperaeration of one or several of the paranasal sinuses that can lead to significant deformation of the overlying bone. Although the presenting complaint of patients with PD is most commonly aesthetic in nature, the condition has also been associated with intracranial tumors and several other serious conditions. Materials and MethodsA meta-analysis of all available clinical publications on the subject of PD was conducted. Patients were categorized on the basis of their sinus involvement. Associated conditions were also identified and categorized. The resulting data were used to further characterize the condition and describe previously unreported associations between PD and other conditions. ResultsTo date, a total of 123 cases of PD have been reported. The frontal sinus was the most commonly involved (63%), followed by the sphenoid sinus (24%), maxillary sinus (20%), and ethmoid sinus (19%). Of patients with symptomatic PD of the frontal sinus, 25% had intracranial pathology (meningioma or arachnoid cyst or orbital tumor). Patients with sphenoid PD had an 83% chance of having associated diagnosis of visual loss, meningioma, or arachnoid cyst, whereas patients with ethmoid PD had 83% chance of having associated diagnosis of exophthalmos, vision loss, or arachnoid cyst. ConclusionsAlthough the presenting complaint of patients with PD is most commonly aesthetic in nature, a significant percentage may have an associated diagnosis. Health care providers must be able to recognize the condition and carry out the appropriate clinical evaluation to avoid missing an associated diagnosis.

Readability assessment of online patient resources for breast augmentation surgery.

Background: Patients increasingly rely on Internet resources for medical information. Well-informed patients are more likely to be active participants in their health care, contributing to higher satisfaction and better overall outcomes. Access to online patient material, however, can be limited by inadequate functional health literacy. The National Institutes of Health and the American Medical Association recommend that educational content be written at a sixth-grade reading level. This study aims to assess the readability of online patient resources for breast augmentation surgery. Methods: A Web search for “breast implant surgery” was performed using the largest public search engine. After sponsored results were excluded, the 12 most accessed sites were identified. Patient-directed information from all relevant articles immediately linked from the main site was downloaded and formatted into plain text. The readability of 110 articles was evaluated using 10 established analyses, both overall and by Web site. Results: The overall average readability of the 12 most popular Internet resources for breast augmentation was at a thirteenth-grade reading level (Coleman-Liau, 13.4; Flesch-Kincaid, 12.7; FORCAST, 11.3; Fry, 13; New Dale-Chall, 12.9; New Gunning Fog, 13.8; Raygor Estimate, 15; and Simple Mesaure of Gobbledygook Formula, 14.3). The Flesch Reading Ease index was 41, which falls into a “difficult” reading category. No individual article or Web site was at the recommended sixth-grade level. Conclusions: Online resources for breast augmentation are above recommended reading levels. This may potentially serve as a barrier to patients seeking this type of surgery. Plastic surgeons should be aware of potential gaps in understanding and direct patients toward more appropriate resources.

Comparing the Outcomes of Different Agents to Treat Vasospasm at Microsurgical Anastomosis during the Papaverine Shortage.

Background: Papaverine remains popular for treating intraoperative vasospasm, but the recent shortage has forced surgeons to trial antispasmodic agents unproven in microsurgery but commonly used in other body areas. During this shortage, the authors have used topical lidocaine and nicardipine to break intraoperative vasospasm. This study aims to analyze the outcomes of these medications on flap complications compared with papaverine. Methods: All consecutive free flaps performed for breast reconstruction at a single institution were reviewed. Data collected included patient demographics, comorbidities, complications, and type of antispasmodic agent. Rates of reexploration, complications, and flap salvage were compared between patients receiving antispasmodic agents and matched papaverine controls. Results: Of the 1087 flaps treated with antispasmodic agents, nicardipine was used on 59 flaps and lidocaine was used on 55 flaps. Patients treated with lidocaine had higher body mass indexes (31.0 kg/m2 versus 27.4 kg/m2; p = 0.001). Patients treated with nicardipine tended to be older (64.0 versus 48.5; p < 0.01) and have a history of hypertension (22.0 percent versus 10.4 percent; p = 0.08) or preoperative irradiation (32.2 percent versus 13.6 percent; p = 0.016) compared with papaverine controls. No differences in the rates of total or partial flap loss, unplanned return to the operating room, or fat necrosis were observed between any of the groups. However, the nicardipine group demonstrated a higher rate of infection (15.3 percent versus 3.4 percent; p = 0.027). Conclusion: Substituting lidocaine or nicardipine for papaverine to treat vasospasm did not demonstrate an increased rate of flap loss or return to the operating room, making these medications safe and efficacious alternatives to papaverine. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Evidence-Based Medicine: The Evaluation and Treatment of Pressure Injuries.

Learning Objective: After studying this article, the participant should be able to: 1. Discuss the approach to and rationale for pressure injury management, including specific techniques for prevention and preoperative evaluation. 2. Develop a management algorithm for these wounds that includes operative and nonoperative modalities. 3. Understand how to identify and manage the complications of surgical intervention for pressure injuries, including recurrence. Summary: Pressure injuries are a common problem associated with great morbidity and cost, often presenting as complex challenges for plastic surgeons. Although the cause of these wounds is largely prolonged pressure, the true pathogenesis involves many other factors, including friction, shear, moisture, nutrition, and infection. This article outlines a systematic approach to evaluating and staging pressure injuries, and provides strategies for treatment and prevention. Critical to surgical intervention is thorough débridement, including any involved or causative bony tissues, and postoperative management to prevent wound dehiscence and recurrence.

Online Patient Resources for Liposuction: A Comparative Analysis of Readability.

BackgroundAs patients strive to become informed about health care, inadequate functional health literacy is a significant barrier. Nearly half of American adults have poor or marginal health literacy skills and the National Institutes of Health and American Medical Association have recommended that patient information should be written at a sixth grade level. The aim of this study is to identify the most commonly used online patient information about liposuction and to evaluate its readability relative to average American literacy. MethodsAn internet search of “liposuction” was performed and the 10 most popular websites identified. User and location data were disabled and sponsored results excluded. All relevant, patient-directed articles were downloaded and formatted into plain text. Articles were then analyzed using 10 established readability tests. A comparison group was constructed to identify the most popular online consumer information about tattooing. Mean readability scores and specific article characteristics were compared. ResultsA total of 80 articles were collected from websites about liposuction. Readability analysis revealed an overall 13.6 grade reading level (range, 10–16 grade); all articles exceeded the target sixth grade level. Consumer websites about tattooing were significantly easier to read, with a mean 7.8 grade level. These sites contained significantly fewer characters per word and words per sentence, as well as a smaller proportion of complex, long, and unfamiliar words. ConclusionsOnline patient resources about liposuction are potentially too difficult for a large number of Americans to understand. Liposuction websites are significantly harder to read than consumer websites about tattooing. Aesthetic surgeons are advised to discuss with patients resources they use and guide patients to appropriate information for their skill level.

Practical Guidelines for Venous Thromboembolism Prophylaxis in Free Tissue Transfer.

Background: Venous thromboembolism encompasses a spectrum of disease, ranging from asymptomatic deep vein thrombosis to fatal pulmonary embolism. As microsurgical techniques increase in complexity, the overriding benefit from a microsurgical versus a venous thromboembolism prophylactic regimen remains unclear. This study evaluated the current recommendations and procedure-specific strategies for venous thromboembolism prophylaxis with a focus on the utility of prophylaxis in microsurgical procedures. Methods: A review was performed to identify all articles discussing the rates of venous thromboembolism in patients undergoing microsurgical procedures. Data were summarized based on body area, including hand, breast, lower extremity, and head and neck. Guidelines for venous thromboembolism prophylaxis in microsurgical cases were established. Results: The available studies demonstrate a reduction in postoperative venous thromboembolism. Unfortunately, chemoprophylaxis continues to be underused throughout plastic surgery, amid concern over the risk of bleeding complications. Based on the best available data, the use of mechanical and chemoprophylaxis should be strongly considered in all microsurgical cases. A preoperative screening algorithm based on a risk-assessment model should be used in all cases to preoperatively characterize and modify risk factors when possible, and plan for perioperative prophylaxis. Conclusions: Although not completely preventable, venous thromboembolism risks can be reduced with careful preoperative planning and medical history and the judicious use of chemoprophylaxis. Because there does not appear to be an increase in the rate of postoperative bleeding when prophylaxis is administered appropriately, the use of venous thromboembolism prophylaxis should be considered in all microsurgery patients except those at extremely high risk of bleeding.

Shark attack-related injuries: Epidemiology and implications for plastic surgeons

BACKGROUND AND AIM The increased media attention to shark attacks has led to a heightened fear and public awareness. Although few sharks are considered dangerous, attacks on humans can result in large soft tissue defects necessitating the intervention of reconstructive surgeons. This study aims to evaluate and describe the characteristics of shark-related injuries in order to improve treatment. METHODS The Global Shark Accident File, maintained by the Shark Research Institute (Princeton, NJ, USA), is a compilation of all known worldwide shark attacks. Database records since the 1900s were reviewed to identify differences between fatal and nonfatal attacks, including: geography, injury pattern, shark species, and victim activity. RESULTS Since the 1900s, there have been 5034 reported shark attacks, of which 1205 (22.7%) were fatal. Although the incidence of attacks per decade has increased, the percentage of fatalities has decreased. Characteristics of fatal attacks included swimming (p = 0.001), boating (p = 0.001), three or more bite sites (p = 0.03), limb loss (p = 0.001), or tiger shark attack (p = 0.002). The most common attacks were bites to the legs (41.8%) or arms (18.4%), with limb loss occurring in 7% of attacks. Geographically, the majority of attacks occurred in North America (36.7%) and Australia (26.5%). Most attacks in the USA occurred in Florida (49.1%) and California (13.6%). CONCLUSIONS Although rare, shark attacks result in devastating injuries to patients. As these injuries often involve multiple sites and limb loss, this creates a significant challenge for reconstructive surgeons. Proper identification of the characteristics of the attack can aid in providing optimal care for those affected.

Academic productivity of faculty associated with microsurgery fellowships

The Hirsch index (h‐index) is widely recognized as a reliable measure of academic productivity. While previous studies have applied the h‐index to surgical disciplines, none have analyzed microsurgery faculty. This manuscript aims to examine the h‐index of microsurgery fellowship faculty to categorize its applicability to microsurgeons as a determinant of academic output.
