RESUMO

BACKGROUND: For the treatment of vascular adverse events caused by filler injections, duplex ultrasound imaging may be used. The findings of duplex ultrasound examination and the clinical features of reticulated livedoid skin patterns were compared with the hemifaces anatomy. OBJECTIVE: The objective of this study was to link the reticulated livedoid skin patterns to the corresponding duplex ultrasound findings and the facial perforasomes. METHODS: Duplex ultrasound imaging was used for the diagnosis and treatment of vascular adverse events. The clinical features and duplex ultrasound findings of 125 patients were investigated. Six cadaver hemifaces were examined to compare the typical livedo skin patterns with the vasculature of the face. RESULTS: Clinically, the affected skin showed a similar reticulated pattern in each facial area corresponding with arterial anatomy and their perforators in the cadaver hemifaces. With duplex ultrasound, a disturbed microvascularization in the superficial fatty layer was visualized. After hyaluronidase injection, clinical improvement of the skin pattern was seen. Normalization of blood flow was noted accompanied by restoration of flow in the corresponding perforator artery. The skin patterns could be linked to the perforators of the superficial fat compartments. CONCLUSION: The livedo skin patterns seen in vascular adverse events may reflect the involvement of the perforators.

RESUMO

BACKGROUND: Resection of soft-tissue sarcomas from the adductor compartment is associated with significant complications. Free/pedicled flaps often are used for wound closure, but their effect on healing is unclear. We compared wound complications, oncologic, and functional outcomes for patients undergoing flap reconstruction or primary closure following resection of adductor sarcomas. METHODS: A total of 177 patients underwent resection of an adductor sarcoma with primary closure (PrC) or free/pedicled flap reconstruction (FR). Patient, tumor, and treatment characteristics were compared, as well as wound complications, oncologic, and functional outcomes (TESS/MSTS87/MSTS93). To examine the relative benefit of flap reconstruction, number needed to treat (NNT) was calculated. RESULTS: In total, 143 patients underwent PrC and 34 had FR, 68% of which were pedicled. There were few differences in demographic, tumor, or treatment characteristics. No significant difference was found in the rate of wound complications. Length of stay was significantly longer in FR (18 days vs. PrC 8 days; p < 0.01). Oncologic and functional outcomes were similar over 5 years follow-up. Uncomplicated wound healing occurred more often in FR compared with PrC for tumors with ≥15 cm (NNT = 8.4) or volumes ≥ 800 ml (NNT = 8.4). Tumors ≤ 336 ml do not benefit from a flap, whereas those > 600 ml are 1.5 times more likely to heal uneventfully after flap closure. CONCLUSIONS: Although flap use prolonged hospitalization, it decreased wound healing complications for larger tumors, and in all sized tumors, it demonstrated similar functional and oncologic outcomes to primary closure. Our size-based treatment criteria can help to identify patients with large adductor sarcomas who could benefit from flap reconstruction. LEVEL OF EVIDENCE III: (Retrospective cohort study).

RESUMO

Currently, a large number of skin biopsies are taken for each true skin cancer case detected, creating a need for a rapid, high sensitivity, and specificity skin cancer detection tool to reduce the number of unnecessary biopsies taken from benign tissue. Picosecond infrared laser mass spectrometry (PIRL-MS) using a hand-held sampling probe is reported to detect and classify melanoma, squamous cell carcinoma, and normal skin with average sensitivity and specificity values of 86-95% and 91-98%, respectively (at a 95% confidence level) solely requiring 10 s or less of total data collection and analysis time. Classifications are not adversely affected by specimen's quantity of melanin pigments and are mediated by a number of metabolic lipids, further identified herein as potential biomarkers for skin cancer-type differentiation, 19 of which were sufficient here (as a fully characterized metabolite array) to provide high specificity and sensitivity classification of skin cancer types. In situ detection was demonstrated in an intradermal melanoma mouse model wherein in vivo sampling did not cause significant discomfort. PIRL-MS sampling is further shown to be compatible with downstream gross histopathologic evaluations despite loss of tissue from the immediate laser sampling site(s) and can be configured using selective laser pulses to avoid thermal damage to normal skin. Therefore, PIRL-MS may be employed as a decision-support tool to reduce both the subjectivity of clinical diagnosis and the number of unnecessary biopsies currently required for skin cancer screening.

RESUMO

BACKGROUND: Flap reconstruction plays an important role in limb preservation after wide resection of extremity soft tissue sarcoma (ESTS), but can be associated with high rates of postoperative wound complications. Currently, no standardized system exists for the classification of these complications. This study aimed to develop a standardized classification system for wound complications after ESTS flap reconstruction. METHODS: Outcomes of ESTS flap reconstructions were analyzed in a retrospective cohort of 300 patients. All wound- and flap-related complications were identified and categorized. Based on these data, a scoring system was developed and validated with a prospective cohort of 100 patients who underwent ESTS flap reconstruction. RESULTS: A 10-point scoring system was developed based on the level of intervention required to treat each complication observed in the retrospective cohort. Raters applied the scoring system to the prospective patient cohort. Validation studies demonstrated excellent inter-rater and intra-rater reliability (weighted Cohen's kappa range, 0.82 [95% CI, 0.5-1.0] to 0.99 [95% CI, 0.98-1.0] and 0.95 [95% CI, 0.84-1.0] to 0.97 [95% CI, 0.92-1.0], respectively). The majority of the raters reported the score to be simple, objective, and reproducible (respective mean scores, 4.76 ± 0.43, 4.53 ± 0.62, and 4.56 ± 0.56 on 5-point Likert scales). CONCLUSION: The Toronto Sarcoma Flap Score (TSFS) is a simple and objective classification system with excellent inter- and intra-rater reliability. Universal adoption of the TSFS could standardize outcome reporting in future studies and aid in the establishment of clinical benchmarks to improve the quality of care in sarcoma reconstruction.

RESUMO

INTRODUCTION: Rates of bilateral mastectomy are rising in women with unilateral, nonhereditary breast cancer. We aim to characterize how psychosocial outcomes evolve after breast cancer surgery. PATIENTS AND METHODS: We performed a prospective cohort study of women with unilateral, sporadic stage 0-III breast cancer at University Health Network in Toronto, Canada between 2014 and 2017. Women completed validated psychosocial questionnaires (BREAST-Q, Impact of Event Scale, Hospital Anxiety & Depression Scale) preoperatively, and at 6 and 12 months following surgery. Change in psychosocial scores was assessed between surgical groups using linear mixed models, controlling for age, stage, and adjuvant treatments. P < .05 were significant. RESULTS: A total of 475 women underwent unilateral lumpectomy (42.5%), unilateral mastectomy (38.3%), and bilateral mastectomy (19.2%). There was a significant interaction (P < .0001) between procedure and time for breast satisfaction, psychosocial and physical well-being. Women having unilateral lumpectomy had higher breast satisfaction and psychosocial well-being scores at 6 and 12 months after surgery compared with either unilateral or bilateral mastectomy, with no difference between the latter two groups. Physical well-being declined in all groups over time; scores were not better in women having bilateral mastectomy. While sexual well-being scores remained stable in the unilateral lumpectomy group, scores declined similarly in both unilateral and bilateral mastectomy groups over time. Cancer-related distress, anxiety, and depression scores declined significantly after surgery, regardless of surgical procedure (P < .001). CONCLUSIONS: Psychosocial outcomes are not improved with contralateral prophylactic mastectomy in women with unilateral breast cancer. Our data may inform women considering contralateral prophylactic mastectomy.

RESUMO

BACKGROUND: Despite the recent surge in rates of immediate breast reconstruction, there is a paucity of large multicenter studies to compare differences in morbidity after immediate versus delayed breast reconstruction. This study used the National Surgical Quality Improvement Program (NSQIP) to study the association between timing of breast reconstruction and complication rates, stratified by reconstructive modality. STUDY DESIGN: The NSQIP database was used to identify breast reconstructions from 2005 to 2012. Rates of major complications were compared by timing within each reconstructive modality (implant vs autologous). Cohort differences in baseline characteristics and variables associated with increased complication rates were identified in bivariate analyses. A multivariable model was created to compare the association between the timing of reconstruction and major complications. RESULTS: Of 24,506 postmastectomy reconstructions, 85.8% were immediate, 14.2% were delayed, 84% were implant, and 16% were autologous reconstructions. Overall, 10.0% of patients suffered a major complication. After stratification, only implant reconstructions showed a statistically higher complication rate with immediate (8.8%) reconstruction compared with delayed (5.3%) (odds ratio, 1.7, P < 0.01). There was no significant difference in complication rates between autologous immediate (18.4%) or delayed (19.0%) reconstructions. After controlling for baseline cohort differences and other risk factors, immediate reconstruction remained as an independent significant predictor of major complications in implant reconstructions (odds ratio, 1.8, P < 0.01). CONCLUSIONS: Immediate rather than delayed breast reconstruction is associated with a significantly higher rate of major complications in implant reconstruction but not in autologous reconstruction. It is important to include these findings in the routine preoperative surgeon-patient discussion of reconstructive options.

RESUMO

BACKGROUND: Whether to undergo postmastectomy breast reconstruction (PMBR) is a challenging, preference-sensitive decision. It is therefore paramount to optimize decision quality through ensuring patients' knowledge and aligning treatments with their personal preferences. This study assessed the effects of a preconsultation educational group intervention (PEGI) on patient knowledge, state-trait anxiety, and decisional conflict (patient uncertainty in decision making) during the decision-making process. METHODS: This phase 3 randomized controlled trial assessed effects of a PEGI in women without active breast cancer undergoing delayed PMBR, or prophylactic mastectomy with immediate PMBR. Both groups underwent routine education before consultation. In addition, the intervention group underwent a PEGI composed of presentations from a plastic surgeon and nurse, a value clarification exercise, and shared experiences from PMBR patients before the consultation with the plastic surgeon. Before and 1-week after consultation, outcome measures were assessed using the Decisional Conflict Scale, State-Trait Anxiety Inventory, and the BREAST-Q. RESULTS: Of the 219 women deemed eligible, a total of 156 women were recruited and randomized. Treatment fidelity was 96% and retention was 88%. At baseline, there were no significant differences in terms of demographic or clinical status, knowledge, state-trait anxiety, and decisional conflict. Patient knowledge about PMBR improved in both groups; however, the degree of knowledge attainment was significantly greater in the PEGI group (24.5% improvement in the intervention group compared with 13.5% in the routine education group, P < 0.001). The reduction in decisional conflict from baseline to follow-up was greater in the intervention group compared with the routine education; however, the difference only approached significance (P = 0.09). CONCLUSIONS: The provision of a preconsultation educational group intervention has been shown to significantly close the knowledge gap on PMBR in patients seeking delayed breast reconstruction or prophylactic mastectomy with immediate breast reconstruction compared with routine education alone.

RESUMO

BACKGROUND: Despite high success rates, flap failure remains an inherent risk in microvascular breast reconstruction. Identifying patients who are at high risk for flap failure would enable us to recommend alternative reconstructive techniques. However, as flap failure is a rare event, identification of risk factors is statistically challenging. Machine learning is a form of artificial intelligence that automates analytical model building. It has been proposed that machine learning can build superior prediction models when the outcome of interest is rare. METHODS: In this study we evaluate machine learning resampling and decision-tree classification models for the prediction of flap failure in a large retrospective cohort of microvascular breast reconstructions. RESULTS: A total of 1012 patients were included in the study. Twelve patients (1.1%) experienced flap failure. The ROSE informed oversampling technique and decision-tree classification resulted in a strong prediction model (AUC 0.95) with high sensitivity and specificity. In the testing cohort, the model maintained acceptable specificity and predictive power (AUC 0.67), but sensitivity was reduced. The model identified four high-risk patient groups. Obesity, comorbidities and smoking were found to contribute to flap loss. The flap failure rate in high-risk patients was 7.8% compared with 0.44% in the low-risk cohort (p = 0.001). CONCLUSIONS: This machine-learning risk prediction model suggests that flap failure may not be a random event. The algorithm indicates that flap failure is multifactorial and identifies a number of potential contributing factors that warrant further investigation.

RESUMO

BACKGROUND: The rates of contralateral prophylactic mastectomy (CPM) are increasing in women with breast cancer. Previous retrospective research has examined clinical and demographic predictors of the uptake of CPM. However, to the authors' knowledge, there has been very little prospective research to date that has examined psychosocial functioning prior to breast cancer surgery to determine whether psychosocial functioning predicts uptake of CPM. The current study was conducted to evaluate demographic, clinical, and psychosocial predictors of the uptake of CPM in women with unilateral breast cancer without a BRCA1 or BRCA2 mutation. METHODS: Women with unilateral non-BRCA-associated breast cancer completed questionnaires prior to undergoing breast cancer surgery. Participants completed demographic and psychosocial questionnaires assessing anxiety, depression, cancer-related distress, optimism/pessimism, breast satisfaction, and quality of life. Pathological and surgical data were collected from medical charts. RESULTS: A total of 506 women consented to participate, 112 of whom (22.1%) elected to undergo CPM. Age was found to be a significant predictor of CPM, with younger women found to be significantly more likely to undergo CPM compared with older women (P < .0001). The rate of CPM was significantly higher in women with noninvasive breast cancer compared with those with invasive breast cancer (P < .0001). Women who elected to undergo CPM had lower levels of presurgical breast satisfaction (P = .01) and optimism (P = .05) compared with women who did not undergo CPM. CONCLUSIONS: Psychosocial functioning at the time of breast cancer surgery decision making impacts decisions related to CPM. Women who have lower levels of breast satisfaction (body image) and optimism are more likely to elect to undergo CPM. It is important for health care providers to take psychosocial functioning into consideration when discussing surgical options.

RESUMO

PURPOSE: To compare psychosocial function outcomes in early breast cancer patients treated with breast-conserving surgery (BCS), mastectomy alone (MA), and mastectomy with immediate breast reconstruction (IBR) at 1 year after surgery. METHODS: Early-stage (stage 0-2) breast cancer patients treated with BCS, MA, and IBR at the University Health Network, Toronto, Ontario, Canada between May 1 2015 and July 31 2016 were prospectively enrolled. Their changes in psychosocial functioning from baseline to 12 months following surgery were compared by using the BREAST-Q, Hospital Anxiety and Depression Scale, and Impact of Event Scale with ANOVA and linear regression. RESULTS: There were 303 early-stage breast cancer patients: 155 underwent BCS, 78 MA, and 70 IBR. After multivariable regression accounting for age, baseline score, income, education, receipt of chemoradiation or hormonal therapy, ethnicity, cancer stage, and unilateral versus bilateral surgery, breast satisfaction was highest in BCS (72.1, SD 19.6), followed by IBR (60.0, SD 18.0), and MA (49.9, SD 78.0) at 12 months, p < 0.001. Immediate breast reconstruction had similar psychosocial well-being (69.9, SD 20.6) compared with BCS (78.5, SD 20.6), p = 0.07. Sexual and chest physical well-being were similar between IBR, BCS, and MA, p > 0.05. CONCLUSIONS: Our study found that in a multidisciplinary breast cancer centre where all three breast ablative and reconstruction options are available to early breast cancer patients, either BCS or IBR can be used to provide patients with a higher degree of satisfaction and psychosocial well-being compared with MA in the long-term.

RESUMO

BACKGROUND: Immediate breast reconstruction has many advantages but is associated with higher complication rates than delayed reconstruction. Complications can delay the delivery of adjuvant cancer treatments. This study aimed to develop and validate a risk stratification model for the prediction of perioperative complications in immediate microvascular breast reconstruction. METHODS: The association between patient and treatment variables and perioperative complications was evaluated in a retrospective cohort of 351 women undergoing immediate breast reconstruction using free deep inferior epigastric artery perforator flaps. Multivariable logistic regression was used to determine the strength of association and weighted scores were assigned. Using cumulative risk scores, patients were stratified into low, intermediate, and high-risk groups. The model was then validated in a prospective cohort of 100 consecutive patients. RESULTS: Obesity, smoking, prior radiation, and comorbidities were important predictors and incorporated into the risk model. Complications occurred in 23.5% of low-risk (95% confidence interval [CI] = 17.7-29.2), 38.4% of intermediate-risk (95% CI = 29.2-47.5) and 53.9% of high-risk (95% CI = 33.3-74.4) patients. Validation confirmed a linear relationship between the risk stratification categories and complications in a model with good predictive power (c-statistic = 0.7, 95% CI = 0.6-0.8). CONCLUSION: A simple risk score, based on known preoperative variables, provides accurate risk stratification for patients considering immediate microvascular breast reconstruction.

RESUMO

BACKGROUND AND OBJECTIVES: The deep inferior epigastric perforator (DIEP) flap may be associated with less long-term donor-site morbidity compared with free muscle-sparing transverse rectus abdominis myocutaneous flap (MS-TRAM) flap. However, DIEP flaps may have longer operative time and higher rates of acute postoperative complications. We performed a cost-effectiveness analysis (CEA) that compared the long-term costs and patient-reported outcomes between the two flaps. METHODS: A retrospective cohort of women who received free MS-TRAM or DIEP flap reconstruction between January 2008 and December 2012, with a minimum of 2-year follow-up, were recruited. Cost data of the primary reconstruction and any subsequent hospitalization due to complications from the reconstruction within 2 years were obtained. Each patient received a BREAST-Q questionnaire at 2 years post-reconstruction. RESULTS: In total, 227 patients (180 DIEP, 47 free MS-TRAM) were included. DIEP patients had significantly fewer abdominal hernia (P = 0.04). The adjusted-incremental cost-effectiveness ratios found that DIEP flap was more cost-effective to free MS-TRAM flap in the domains of "Physical Well-Being of the Abdomen" and "Satisfaction with Outcome." CONCLUSIONS: DIEP flap is the more cost-effective method of autologous breast reconstruction in the long-term compared with free MS-TRAM flap with respect to patient-reported abdominal well-being and overall satisfaction with the outcome.

RESUMO

BACKGROUND: Lentigo maligna is an in situ form of cutaneous melanoma that commonly arises on the head and neck. Various surgical and nonsurgical treatment options are available but no randomized trials exist to guide practice. OBJECTIVE: To determine the current treatment practices for lentigo maligna of the head and neck in Ontario, Canada. MATERIALS AND METHODS: Cross-sectional survey of dermatologists, plastic surgeons, and head and neck surgeons. RESULTS: The response rate was 35% (190/542). Wide excision with immediate reconstruction was the most commonly recommended treatment for tumors on the cheek (69%), whereas staged excision with margin control was recommended most often for tumors on the nasal ala (60%). Overall, 5 mm was the most frequently recommended initial surgical margin (69%); 26.5% of respondents recommended margins wider than 5 mm. For tumors on the nasal ala, eyelid, and ear helix, more than 30% of respondents recommended an initial margin narrower than 5 mm. CONCLUSION: Although surgical excision is the predominant treatment modality for lentigo maligna on the head and neck, practices vary considerably in terms of the type of excision and the initial margin used. Potential response bias and the geographic restriction of our sample may limit the generalizability of our results.

RESUMO

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a rare disease that has been diagnosed in an extremely small proportion of women with breast implants. The pathogenesis of this disease is currently poorly understood, but it appears to be related to textured implants. Recent high-profile media coverage of this rare clinical entity is likely to cause considerable anxiety for breast cancer patients who have undergone alloplastic breast reconstruction. The purpose of this review is to provide surgical oncologists with an evidence-based overview of the incidence, diagnosis, and management of BIA-ALCL with a particular emphasis on breast reconstruction cases. It is essential that surgical oncologists are familiar with BIA-ALCL, because although it is extremely rare, early recognition and surgical resection will be curative in many cases.

RESUMO

BACKGROUND: Chronic postsurgical pain (CPSP) is a debilitating and costly condition. Risk factors for CPSP after autologous breast reconstruction have not been clearly established. Previously, we demonstrated that transversus abdominis plane (TAP) catheters delivering intermittent local anesthetic reduced postoperative morphine consumption. This prospective follow-up study aimed to (1) compare the incidence of CPSP after autologous breast reconstruction between patients who received postoperative intermittent TAP catheters with bupivacaine or saline boluses and (2) assess the factors that contribute to the development and maintenance of CPSP in this study cohort. METHODS: Ninety-three patients who underwent deep inferior epigastric artery perforator or muscle-sparing transverse rectus abdominis breast reconstruction were randomized to receive TAP catheters with bupivacaine or saline postoperatively. Subsequently, patients were followed for a year to assess persistent pain, pain severity, quality of life scores, and functional disability at 6 and 12 months after surgery. RESULTS: Twenty-four percent and 23% of patients reported CPSP at 6 and 12 months, respectively. There were no significant differences between groups (bupivacaine vs. placebo) on pain-related variables, including incidence of CPSP. Patients who reported greater variability in pain scores at rest over the first 48 hours postoperatively were more likely to have CPSP 6 months, but not 12 months, later. CONCLUSIONS: Acute postoperative pain variability may contribute to the development of CPSP up to 6 months after autologous breast reconstruction surgery. Neither postoperative use of bupivacaine vs. saline in the TAP catheters nor acute pain severity influenced the 6- or 12-month incidence of CPSP.

RESUMO

INTRODUCTION: The ACS-NSQIP surgical risk calculator is an open-access on-line tool that estimates the risk of adverse post-operative outcomes for a wide range of surgical procedures. Wide surgical resection of soft tissue sarcoma (STS) often requires complex reconstructive procedures that can be associated with relatively high rates of complications. This study evaluates the ability of this calculator to identify patients with STS at risk for post-operative complications following flap reconstruction. METHODS: Clinical details of 265 patients who underwent flap reconstruction following STS resection were entered into the online calculator. The predicted rates of complications were compared to the observed rates. The calculator model was validated using measures of prediction and discrimination. RESULTS: The mean predicted rate of any complication was 15.35 ± 5.6% which differed significantly from the observed rate of 32.5% (P = 0.009). The c-statistic was relatively low at 0.626 indicating poor discrimination between patients who are at risk of complications and those who are not. The Brier's score of 0.242 was significantly different from 0 (P < 0.001) indicating poor correlation between the predicted and actual probability of complications. CONCLUSION: The ACS-NSQIP universal risk calculator did not maintain its predictive value in patients undergoing flap reconstruction following STS resection. J. Surg.

RESUMO

BACKGROUND: Achieving an aesthetic outcome following postmastectomy breast reconstruction is both an important goal for the patient and plastic surgeon. However, there is currently an absence of a widely accepted, standardized, and validated professional aesthetic assessment scale following postmastectomy breast reconstruction. METHODS: A systematic review was performed to identify all articles that provided professional assessment of the aesthetic outcome following postmastectomy, implant- or autologous tissue-based breast reconstruction. A modified version of the Scientific Advisory Committee's Medical Outcomes Trust (MOT) criteria was used to evaluate all professional aesthetic assessment scales identified by our systematic review. The criteria included conceptual framework formation, reliability, validity, responsiveness, interpretability, burden, and correlation with patient-reported outcomes. RESULTS: A total of 120 articles were identified: 52 described autologous breast reconstruction, 37 implant-based reconstruction, and 29 both. Of the 12 different professional aesthetic assessment scales that exist in the literature, the most commonly used scale was the four-point professional aesthetic assessment scale. The highest score on the modified MOT criteria was assigned to the ten-point professional aesthetic assessment scale. However, this scale has limited clinical usefulness due to its poor responsiveness to change, lack of interpretability, and wide range of intra- and inter-rater agreements (Veiga et al. in Ann Plast Surg 48(5):515-520, 2002). CONCLUSIONS: A "gold standard" professional aesthetic assessment scale needs to be developed to enhance the comparability of breast reconstruction results across techniques, surgeons, and studies to aid with the selection of procedures that produce the best aesthetic results from both the perspectives of the surgeon and patients.

RESUMO

PURPOSE: Breast cancer survivors who make preference-sensitive decisions about postmastectomy breast reconstruction often have large gaps in knowledge and undergo procedures that are misaligned with their treatment goals. We evaluated the feasibility and effect of a pre-consultation educational group intervention on the decision-making process for breast reconstruction. METHODS: We conducted a pilot randomized controlled trial (RCT) where participants were randomly assigned to the intervention with routine education or routine education alone. The outcomes evaluated were decisional conflict, decision self-efficacy, satisfaction with information, perceived involvement in care, and uptake of reconstruction following surgical consultation. Trial feasibility and acceptability were evaluated, and effect sizes were calculated to determine the primary outcome for the full-scale RCT. RESULTS: Of the 41 patients enrolled, recruitment rate was 72 %, treatment fidelity was 98 %, and retention rate was 95 %. The Cohen's d effect size in reduction of decisional conflict was moderate to high for the intervention group compared to routine education (0.69, 95 % CI = 0.02-1.42), while the effect sizes of increase in decision self-efficacy (0.05, 95 % CI = -0.60-0.71) and satisfaction with information (0.11, 95 % CI = -0.53-0.76) were small. A higher proportion of patients receiving routine education signed informed consent to undergo breast reconstruction (14/20 or 70 %) compared to the intervention group (8/21 or 38 %) P = 0.06. CONCLUSIONS: A pre-consultation educational group intervention improves patients' shared decision-making quality compared to routine preoperative patient education. A full-scale definitive RCT is warranted based on high feasibility outcomes, and the primary outcome for the main trial will be decisional conflict.

RESUMO

BACKGROUND: The importance of facial contouring with facial nerve reconstruction following total and radical parotidectomy is often overlooked. The goal of this study was to quantify the level of facial disfigurement and nerve dysfunction following reconstruction of the facial nerve, with or without reconstruction of the contours, using free tissue transfer. METHODS: A total of 26 patients with radical parotidectomy and facial nerve reconstruction were included in this retrospective study. Of the 26 patients, 15 underwent follow-up interviews and evaluation of facial nerve function and disfigurement using three different scales: the regional House-Brackmann (H-B) scale, the Facial Clinimetric Evaluation (FaCE) Scale, and the observer-rated disfigurement scale. RESULTS: Of the 15 evaluated patients, 8 patients underwent free tissue transfer. Mean follow-up time was 39 months (median, 35; range, 11-65 months). Of the 15 patients, 10 patients had good or moderate function according to the H-B mouth scale (median score, 4; range, 2-5), and satisfactory eye closure was observed in 10 patients (median score, 3; range, 2-5). The mean disfigurement value rated by the physician was 5 (scale, 1-9), with a mean patient rating of 4. Subjective total FaCE score varied significantly (mean, 52; range, 13-93). CONCLUSIONS: Facial nerve and soft tissue reconstruction are highly beneficial to patients undergoing radical parotidectomy.
