Keystone Flap for Closure of Skin Cancer Defects on the Upper Extremity.

Background: We sought to examine the efficacy of the Keystone Design Perforator Island Flap (KDPIF) for the reconstruction of skin cancer excision defects isolated to the upper extremity. In particular, to examine the size of defects repaired and the complications associated with the keystone flap procedure isolated to the upper extremity. Methods: This is a retrospective chart review including all patients older than 18 years of age who received a KDPIF procedure between February 2013 and February 2019 for the oncologic reconstruction of skin cancer defects isolated to the upper extremities by a single surgeon. All procedures were done according to the original description by Behan. Results: A total of 32 patients, 18 (56%) male and 14 (44%) female, received 35 keystone flaps between February 2013 and February 2019. The mean age of the males and females was 70.5 and 79.7 years of age, respectively. Thirty-five lesions suspicious for cancer were excised and 14 (40%) basal cell carcinoma (BCC), 11 (31%) squamous cell carcinoma (SCC), 9 (26%) melanoma, and 1 (3%) actinic keratoses diagnoses were histopathologically determined. Skin defect excisions varied from 3.53 cm2 to 31.42 cm2. No intraoperative or postoperative complications occurred. Conclusions: The keystone flap is a successful versatile flap procedure with a low or absent complication rate for the reconstruction of skin cancer excision defects of various locations (eg arm, hand, elbow, forearm, shoulder, and wrist), cancer pathologies, and sizes on the upper extremity. When needed, a Doppler may successfully identify adequate perforating blood vessels for the relatively larger flaps.

La surface de peau manquante due à l'excision était comprise entre 3.53 cm2 et 31.42 cm2. Aucune complication peropératoire ou postopératoire n'est survenue. Conclusions: Le volet en clé de voûte KDPIF est une procédure versatile efficace ayant un taux de complication faible ou nul pour la reconstruction pour manque de peau après excision de cancer cutané à divers emplacements (bras, main, coude, avant-bras, épaule, poignet), des pathologies cancéreuses et des tailles variables sur le membre supérieur. Quand cela est nécessaire, un examen Doppler peut identifier avec succès les vaisseaux sanguins perforants pour les volets relativement plus grands.

A Review of Lymphedema for the Hand and Upper-Extremity Surgeon.

Secondary lymphedema of the upper limb is frequently seen in Western countries after cancer treatment (most often breast in women). It is a chronic disease that affects quality of life and functioning. In its extreme form, it may be debilitating. A review is given of the pathology, nonsurgical treatment, and surgical treatment with a protocol.

Percutaneous Purse-String Suture: An Innovative Percutaneous Technique for Inframammary Fold Creation and Improved Breast Projection in Reconstructive Surgery.

BACKGROUND: Lipofilling for breast reconstruction has become increasingly common. Creation of a well-defined inframammary fold (IMF) is integral to achieving symmetrical aesthetic results. This has traditionally been done under direct vision through an open incision. OBJECTIVES: The authors present their experience in reconstructive breast surgery with a novel percutaneous technique for IMF creation and improvement of projection without the need for large incisions. METHODS: From June 2011 to January 2015, 180 patients underwent a percutaneous purse-string suture (PPSS) to enhance their IMF and improve breast projection. After completion of lipofilling, a curved cannula is tunneled subcutaneously. The suture is placed into the cannula and passed around the circumference of the breast footprint. After the completion of two passes in different anatomic levels around the footprint, the suture is tightened at the breast's tail zone to achieve the desired IMF definition and breast projection. Surgical technique, results, and follow up are presented. RESULTS: The PPSS technique was combined either with lipofilling only or as part of flap breast reconstruction in 30 and 150 patients, respectively. The average follow-up time was 34 months (range, 11-48 months). PPSS was redone in 25 patients to further improve breast projection. One patient complained of postoperative pain. No other PPSS-related complication was reported. CONCLUSIONS: PPSS is an innovative technique designed to complement the emerging field of lipofilling for breast reconstruction. The technique is safe, easily reproduced, and provides excellent results. Breast IMF and projection are immediately improved without the need for open incisions.

The vascularized groin lymph node flap (VGLN): Anatomical study and flap planning using multi-detector CT scanner. The golden triangle for flap harvesting.

INTRODUCTION: A growing number of surgeons perform lymph node transfers for the treatment of lymphedema. When harvesting a vascularized lymph node groin flap (VGLNF) one of the major concerns is the potential risk of iatrogenic lymphedema of the donor-site. This article helps understanding of the lymph node distribution of the groin in order to minimize this risk. MATERIALS AND METHODS: Fifty consecutive patients undergoing abdominal mapping by multi-detector CT scanner were included and 100 groins analyzed. The groin was divided in three zones (of which zone II is the safe zone) and lymph nodes were counted and mapped with their distances to anatomic landmarks. Further node units were plotted and counted. RESULTS: The average age was 48 years. A mean number of nodes of 6.5/groin was found. In zone II, which is our zone of interest a mean of 3.1 nodes were counted with a mean size of 7.8 mm. In three patients no nodes were found in zone II. In five patients nodes were seen in zone II but were not sufficient in size or number to be considered a lymph node unit. On average the lymph node unit in zone II was found to be 48.3 mm from the pubic tubercle when projected on a line from the pubic tubercle to the anterior superior iliac spine, 16.0 mm caudal to this line, and 20.4 mm above the groin crease. On average the lymph node unit was a mean of 41.7 mm lateral to the SCIV-SIEV confluence. CONCLUSION: This study provides increased understanding of the lymphatic anatomy in zone II of the groin flap and suggests a refined technique for designing the VGLNF. As with any flap there is a degree of individual patient variability. However, having information on the most common anatomy and flap design is of great value.

Improving journal clubs through the use of positive deviance: A mixed-methods study.

BACKGROUND: Plastic surgery journal clubs are often unsatisfactory for both surgeons and residents, leading to frustration and poor surgeon attendance. OBJECTIVE: To assess and modify journal clubs using the principles of positive deviance. METHODS: Surgeons and residents were surveyed across five domains before and after journal club modification. These included perception of the quality of articles chosen, the quality of the presentations, postpresentation discussions, educational benefit and overall satisfaction. RESULTS: Using the principles of positive deviance, the authors were able to identify points of concern with journal clubs and make suggestions for improvement. Postintervention surveys demonstrated a statistically significant improvement in journal clubs across all five domains assessed. CONCLUSIONS: Using the principles of positive deviance, journal club satisfaction was improved. The interventions presented could be used to improve journal clubs at other institutions. In addition, the principles of positive deviance can be used to address a variety of administrative and educational challenges faced by plastic surgery programs.

Teaching ear reconstruction using an alloplastic carving model.

BACKGROUND: Ear reconstruction is challenging surgery, often with poor outcomes. Our purpose was to develop a surgical training model for auricular reconstruction. METHODS: Silicone costal cartilage models were incorporated in a workshop-based instructional program. Trainees were randomly divided. Workshop group (WG) participated in an interactive session, carving frameworks under supervision. Nonworkshop group (NWG) did not participate. Standard Nagata templates were used. Two further frameworks were created, first with supervision then without. Groups were combined after the first carving because of frustration in the NWG. Assessment was completed by 3 microtia surgeons from 2 different centers, blinded to framework origin. Frameworks were rated out of 10 using Likert and visual analog scales. Results were examined using SPSS (version 14), with t test, ANOVA, and Bonferroni post hoc analyses. RESULTS: Cartilaginous frameworks from the WG scored better for the first carving (WG 5.5 vs NWG 4.4), the NWG improved for the second carving (WG 6.6 vs NWG 6.5), and both groups scored lower with the third unsupervised carving (WG 5.9 vs NWG 5.6). Combined scores after 3 frameworks were not statistically significantly different between original groups. A statistically significant improvement was demonstrated for all carvers between sessions 1 and 2 (P ≤ 0.09), between sessions 1 and 3 (P ≤ 0.05), but not between sessions 2 and 3, thus suggesting the necessity of in vitro practice until high scores are achieved and maintained without supervision before embarking on in vivo carvings. Quality of carvings was not related to level of training. CONCLUSIONS: An appropriate and applicable surgical training model and training method can aid in attaining skills necessary for successful auricular reconstruction.

A descriptive examination of the impact of sternal scar formation in women.

Formation of abnormal scars is a significant source of morbidity following sternotomy. We undertook a descriptive exploratory mixed methods study of women (n=13) who participated in the Women's Recovery from Sternotomy Trial to examine the: (1) qualitative impact of the cosmetic result of sternotomy, and (2) quantitative association between subjective satisfaction and objective ratings of the sternal scar. Conventional content analysis was used to analyze the data generated from semi-structured interviews. Though the participants appreciated that having the scar was a cost of reaping the benefits of having cardiac surgery, they were not well prepared to learn to live with the scar. The scar was a poignant personal reminder that they had a health problem and underwent a distressing surgery, and it often rendered them feeling less attractive. The scar also had a public presence that they perceived rendered judgment from others. There was little association between the participants' subjective satisfaction (rated on a likert-type scale) and the objective scar rating using the Beausang Clinical Scar Assessment (r=0.348, p=0.294). The subjective perception of the sternal scar is of importance to women. Thus, appropriate preparation, post-operative counseling and support regarding the sternal scar are warranted.

The effectiveness of pressure garment therapy for the prevention of abnormal scarring after burn injury: a meta-analysis.

OBJECTIVES: This study had three objectives. First, to conduct a systematic review to identify the available evidence for the use of pressure garment therapy (PGT); second, to assess the quality of the available evidence; and third, to conduct a meta-analysis to quantify the effectiveness of PGT for the prevention of abnormal scarring after burn injury. BACKGROUND: Standard care for the prevention of abnormal scarring after burn injury includes pressure garment therapy (PGT); however, it is associated with potential patient morbidity and high costs. We hypothesise that an assessment of the available evidence supporting the use of pressure garment therapy will aid in directing clinical care and future research. METHODS: Randomised control trials were identified from CINHAL, EMBASE, MEDLINE, CENTRAL, the 'grey literature' and hand searching of the Proceedings of the American Burn Association. Primary authors and pressure garment manufacturers were contacted to identify eligible trials. Bibliographies from included studies and reviews were searched. Study results were pooled to yield weighted mean differences or standardised mean difference and reported using 95% confidence intervals. RESULTS: The review incorporated six unique trials involving 316 patients. Original data from one unpublished trial were included. Overall, studies were considered to be of high methodological quality. The meta-analysis was unable to demonstrate a difference between global assessments of PGT-treated scars and control scars [weighted mean differences (WMD): -0.46; 95% confidence interval (CI): -1.07 to 0.16]. The meta-analysis for scar height showed a small, but statistically significant, decrease in height for the PGT-treated group standardised mean differences (SMD): -0.31; 95% CI: -0.63, 0.00. Results of meta-analyses of secondary outcome measures of scar vascularity, pliability and colour failed to demonstrate a difference between groups. CONCLUSIONS: PGT does not appear to alter global scar scores. It does appear to improve scar height, although this difference is small and of questionable clinical importance. The beneficial effects of PGT remain unproven, while the potential morbidity and cost are not insignificant. Given current evidence, additional research is required to examine the effectiveness, risks and costs of PGT.

Superior pedicle breast reduction techniques increase the risk of postoperative drainage.

BACKGROUND: The most frequent complication after bilateral reduction mammoplasty (BRM) is the formation of seromas and hematomas. If a group of patients who are at increased risk of seroma and hematoma are identified, the use of drains in this group would be beneficial. We hypothesized that superior pedicle reductions would have increased postoperative drainage. METHODS: A prospective observational study was conducted to identify independent risk factors for increased drainage after BRM. Blinded research nurses were employed to record the amount of drainage during the postoperative period. Univariate and multivariate regression analyses were used to identify risk factors for increased postoperative drainage. RESULTS: The study included a total of 111 patients. Univariate analysis identified the amount of preoperative infiltration (P < 0.001), the amount of liposuction (P < 0.001), the amount of surgically resected tissue (P = 0.001), the type of reduction (P < 0.001), the patient's chest circumference (P = 0.035), and the patient's body mass index (BMI) (P = 0.015) as significant predictors of postoperative drainage. Multivariate regression analysis identified the amount of tissue resected and the type of reduction as the only 2 independent predictors of postoperative drainage. The use of superior pedicle technique predicted 43% of the variability in postoperative wound drainage. CONCLUSIONS: The use of the superior pedicle technique for BRM is associated with a significant increase in postoperative drainage. Surgeons using this technique should consider the routine use of drains to avoid possible complications of seroma, infection, and poor wound healing.

Primary transcutaneous lower blepharoplasty with routine lateral canthal support: a comprehensive 10-year review.

BACKGROUND: Rejuvenation of the lower eyelid often requires tightening of excess skin and muscle and removal or transposition of orbital fat. Although transcutaneous lower blepharoplasty can accomplish these aesthetic demands, it has been associated with an increased risk of lower lid malposition. Routine lateral canthal support during lower blepharoplasty has recently been advocated to minimize this risk. This study reviewed the outcome of a surgeon's 10-year experience with primary lower transcutaneous blepharoplasty and lateral canthal support consisting of canthopexy, canthoplasty, and orbicularis suspension. METHODS: A retrospective chart review of a primary lower transcutaneous blepharoplasty series over a 10-year period was performed. Patients with a history of prior eyelid surgery for blepharoplasty or midface lift were excluded. Preoperative demographic and morphological data from patient charts and standardized photographs obtained before and after surgery were evaluated by an independent observer. Surgical technique and management of complications were determined from operative reports and clinical notes. RESULTS: There were 264 patients with a median follow-up of 264 days (range, 60 to 2410 days). Lid malposition requiring operative correction occurred in nine patients (3.5 percent). Additional complications included orbital hematoma in one patient (0.4 percent), chemosis in 32 patients (12.1 percent), and blepharitis in 10 patients (3.8 percent). Minor surgical revisions unrelated to lid malposition were performed on 31 patients (11.7 percent) for correction of subciliary incision cysts or granulomas, canthal suture inflammation, and canthal webbing. CONCLUSIONS: Lateral canthal support should be considered a routine component of lower transcutaneous blepharoplasty to obtain the desired aesthetic result and maintain the natural appearance of the eyelid shape. The associated complication rate is acceptable.

Completely autologous platelet gel in breast reduction surgery: a blinded, randomized, controlled trial.

BACKGROUND: The objective of this study was to assess the effectiveness of topical application of completely autologous platelet gel during breast surgery to reduce postoperative wound drainage. An increasing number of surgical centers are using tissue sealants to reduce postoperative drainage and improve surgical outcomes. However, there is a paucity of randomized, double-blind, controlled trials assessing the efficacy of these agents. METHODS: The authors conducted a within-patient, randomized, patient- and assessor-blinded, controlled trial assessing the use of completely autologous platelet gel in 111 patients undergoing bilateral reduction mammaplasty. Patients were randomized to receive the gel applied to the left or right breast after hemostasis was achieved; the other breast received no treatment. The primary outcome was the difference in wound drainage over 24 hours. Secondary outcomes included subjective and objective assessments of pain and wound healing. RESULTS: No statistically significant differences in the drainage, level of pain, size of open areas, clinical appearance, degree of scar pliability, or scar erythema were noted. CONCLUSION: The authors' results do not support the use of completely autologous platelet gel to improve outcomes after reduction mammaplasty.

Continuing medical education in emergency plastic surgery for referring physicians: a prospective assessment of educational needs.

BACKGROUND: Continuing medical education for referring physicians is an essential part of raising the profile of plastic surgery and improving patient care. The authors conducted a prospective cohort study to assess the educational needs of emergency and primary care physicians who refer patients to the on-call plastic surgeon. METHODS: The following information was collected for telephone referrals from emergency and primary care physicians over a 1-year period: date, location of referral center, population of referral center, distance between referral center and tertiary care hospital, patient age, presenting problem, anatomical location of the problem, and treatment plan proposed by the plastic surgeon. In addition, the 50 physicians who most frequently referred patients were surveyed to identify which topics they perceived to be of the highest educational utility and which were frequently encountered. RESULTS: There were a total of 1077 referrals to on-call plastic surgeons, mostly for trauma (83 percent) and injuries involved primarily the upper extremity (65 percent) or head and neck regions (26 percent). Five percent or more of all referrals involved mandible, phalangeal, metacarpal, or zygomatico-orbital complex fractures, minor burns, flexor tendon injuries, single digits requiring revision of an amputation, and extensor tendon injuries. Referring physicians reported that the topics of most educational utility were management of hand infections, minor burns, nasal fractures, boxer's fractures, complex facial lacerations, frostbite, metacarpal fractures, and scaphoid fractures. CONCLUSIONS: To have the greatest potential affect on changing physicians' behavior and improving patient care, continuing medical education should focus on traumatic injuries to the upper extremity and head and neck regions. A prioritized list of topics should include management of minor burns, hand fractures, hand infections, nasal infections, and complex facial lacerations.

Nontuberculous mycobacterial breast implant infections.

BACKGROUND: For reasons that are unclear, the incidence of nontuberculous mycobacterial disease is increasing worldwide. Periprosthetic nontuberculous mycobacterial infections following augmentation mammaplasty and breast reconstruction have been reported previously in the form of case reports. METHODS: This retrospective case series examines periprosthetic nontuberculous mycobacterial infections in two western Canadian cities (Edmonton, Alberta, and Vancouver, British Columbia) over a 10-year time period. RESULTS: Ten patients were identified, four of whom had bilateral infections. The most common isolate was Mycobacterium fortuitum. Clinical features were similar to nonmycobacterial periprosthetic infections. The median time to onset of symptoms was 4.5 weeks and the median time to culture an organism was 5.4 weeks. The median duration of antibiotic therapy was 22 weeks. Patients required a mean of three additional operations after diagnosis. Nine patients underwent explantation of the involved implant(s). Reimplantation was performed in six patients a median of 11.5 months after explantation. All cases of reimplantation were successful. CONCLUSIONS: Experience with this postoperative complication is limited, as nontuberculous mycobacteria represent a minority of the pathogens responsible for periprosthetic infections. In the absence of specific features with which to identify patients at risk, the surgeon must be aware of the possibility of this infection. To achieve earlier diagnosis, the clinician should have a high index of suspicion in a patient with delayed onset of symptoms, negative preliminary cultures, and a periprosthetic infection that fails to resolve following a course of conventional antimicrobial treatment. With appropriate treatment, nontuberculous mycobacterial periprosthetic infections can be managed successfully.

Quality-of-life and outcome predictors following massive burn injury.

BACKGROUND: Quality of life is a major criterion when decisions regarding resuscitation, reconstruction, and rehabilitation of patients with massive burn injuries are being considered. There has been little research focusing on quality of life following burn injuries involving more than 50 percent total body surface area in the adult population. The authors' goals were to describe quality of life and identify specific clinical and functional indices that predict good quality of life following massive burn injuries. METHODS: Using a prospective study design, 47 patients who survived a massive burn between 1980 and 2001 were recruited from a single burn unit. Clinical data were collected from hospital records, function was assessed using the Abbreviated Burn-Specific Health Scale, and quality of life was assessed using the Short Form-36 survey. The Short Form-36 scores were compared with population norms. Univariate and multivariate regression analyses were used to identify factors predicting Short Form-36 scores. RESULTS: Overall, the mean age was 28 +/- 1.8 years, 96 percent (45 of 47) were men, and the mean burn size was 64 +/- 2.1 percent total body surface area. Compared with Canadian population norms, burn patients had significantly lower Short Form-36 scores in the domains of role physical (69.1 versus 82.1, p = 0.0067) and general health perception (67.2 versus 77.0, p = 0.00014). At the time of injury, the amount of total full-thickness burn predicted follow-up Short Form-36 physical summary scores (R2 = 15 percent, p < 0.001). At the time of follow-up, addition of the patient's hand function significantly contributed to the prediction of Short Form-36 physical summary scores (R2 = 44 percent, p < 0.001). At the time of injury, the age of the patient predicted follow-up Short Form-36 mental summary scores (R2 = 25 percent, p < 0.001). At the time of follow-up, addition of the patient's perceived level of social support significantly contributed to the prediction of Short Form-36 mental summary scores (R2 = 44 percent, p < 0.001). CONCLUSIONS: Survivors of massive burn injury reported a good quality of life in most Short Form-36 domains. The authors identified the size of the total full-thickness injury and the age of the patient as factors available at the time of injury that predict quality of life. The addition of hand function and the patient's perceived level of social support at the time of follow-up improved prediction of quality of life. Accordingly, this information on quality of life after massive burn injury could aid in decision making at the time of resuscitation, reconstruction, and rehabilitation.

Radiologic and patient-reported functional outcomes in an elderly cohort with conservatively treated distal radius fractures.

PURPOSE: There have been few prospective studies of elderly patients with conservatively treated distal radius fractures and little is known about the relationship between acceptable radiographic reduction and functional outcomes in this population. We hypothesized that acceptable fracture reduction (according to standard radiographic dorsal/volar tilt criteria) would be associated with better functional outcomes and greater satisfaction. METHODS: Seventy-four patients who were at least 50 years of age with conservatively managed distal radius fractures were recruited from 2 large urban emergency departments from January 2001 to December 2001. Patients with wrist fractures treated in the emergency department and discharged home were included; patients admitted to the hospital or who required surgical reduction were excluded. Standard lateral radiographs were taken after the final cast was removed. These were reviewed independently by a reference-standard musculoskeletal radiologist and the degree of dorsal/volar tilt was recorded. This value was dichotomized according to standard published dorsal/volar tilt criteria as acceptable (dorsal tilt <10 degrees or volar tilt <20 degrees ) or unacceptable (dorsal tilt >10 degrees or volar tilt >20 degrees ). The Medical Outcomes Study Short-Form 12 (SF-12); the Disabilities of the Arm, Shoulder, and Hand questionnaire; and a patient satisfaction survey were used to assess patient-reported outcomes 6 months after the injury. RESULTS: The average dorsal/volar tilt measured by the reference standard radiologist was 3.4 degrees (SD=13.6) dorsal; overall 47 patients (64%) were considered to have an acceptable radiographic reduction. Acceptable radiographic reduction was not associated with better generic physical or mental health status, lesser degrees of upper-extremity disability, or greater satisfaction with outcomes than was unacceptable reduction. Overall 44 of 74 patients (59%) reported being satisfied or very satisfied with their functional status at 6 months. CONCLUSIONS: Contrary to our hypotheses we found that acceptable radiographic reduction (according to dorsal/volar tilt criteria) was not associated with better self-reported functional outcomes or increased satisfaction at 6 months in elderly patients with conservatively treated distal radius fractures.
