ESPRAS Survey: National and European Societies for Plastic Surgeons.

BACKGROUND: The European Society of Plastic, Reconstructive and Aesthetic Surgery (ESPRAS) comprises 40 national societies across Europe. In addition to ESPRAS, there are 8 different European Plastic Surgery societies representing Plastic Surgeons in Europe. The 4th European Leadership Forum (ELF) of ESPRAS, held under the motto "Stronger together in Europe" in Munich in 2023, aimed to collect and disseminate information regarding the national member societies of ESPRAS and European societies for Plastic Surgeons. The purpose was to identify synergies and redundancies and promote improved cooperation and exchange to enhance coordinated decision-making at the European level. MATERIAL AND METHODS: An online survey was conducted regarding the organisational structures, objectives and challenges of national and European societies for Plastic Surgeons in Europe. This survey was distributed to official representatives (Presidents, Vice Presidents and General Secretaries) and delegates of national and European societies at the ELF meeting. Missing information was completed using data obtained from the official websites of the respective European societies. Preliminary results were discussed during the 4th ELF meeting in Munich in March 2023. RESULTS: The ESPRAS survey included 22 national and 9 European Plastic Surgery societies representing more than 7000 Plastic Surgeons in Europe. Most national societies consist of less than 500 full members (median 182 members (interquartile range (IQR) 54-400); n=22). European societies, which covered the full spectrum or subspecialities, differed in membership types and congress cycles, with some requiring applications by individuals and others including national societies. The main purposes of the societies include research, representation against other disciplines, specialisation and education as well as more individual goals like patient care and policy regulation. CONCLUSION: This ESPRAS survey offers key insights into the structures, requirements and challenges of national and European societies for Plastic Surgeons, highlighting the relevance of ongoing close exchange between the societies to foster professional advancement and reduce redundancies. Future efforts of the ELF will continue to further explore strategies for enhancing collaboration and harmonisation within the European Plastic Surgery landscape.

Translation and validation of a Finnish version of the Facial Clinimetric Evaluation (FaCE) Scale.

BACKGROUND: The Facial Clinimetric Evaluation (FaCE) scale is a patient-reported health status instrument developed for assessing the health-related quality of life (HRQoL) in patients with facial nerve paralysis. The aim of this study was to translate and validate the FaCE scale for the Finnish-speaking population. METHODS: The FaCE scale was translated according to international guidelines. Sixty patients in an outpatient clinic prospectively completed the translated FaCE scale and generic HRQoL instrument (15D). The objective facial paralysis grading was made using the Sunnybrook and House-Brackmann scales. Repeated FaCE and 15D instruments were mailed to patients 2 weeks later. Total scores of the FaCE instrument and subscales were calculated, and floor and ceiling effects were examined. Exploratory factor analysis was made. Internal consistency, reliability, and repeatability were assessed. Convergence with 15D instrument, Sunnybrook, and House-Brackmann scales was examined. RESULTS: The total internal consistency of the FaCE scale was high (Cronbach's alpha 0.83). There were no statistically significant differences found between mean scores of the subscales in test-retest analysis (p > 0.05). Intra-class correlations coefficients were high, ranging between 0.78 and 0.92, and the correlations were statistically significant (p < 0.001). There were statistically significant correlations observed between the FaCE scale and the 15D, Sunnybrook, and House-Brackmann scores. CONCLUSION: The FaCE scale was successfully translated and validated in Finnish with good validity and reliability. We also demonstrated statistically significant correlations between the generic HRQoL15D instrument and both the Sunnybrook and House-Brackmann physician-based grading scales. The FaCE scale is now ready for use in Finnish facial paralysis patients.

Comprehensive outcome analysis in two composite face transplants in Helsinki: Have we succeeded?

INTRODUCTION: There is a need to define what is success after face transplantation (FT). We have previously created a four-component criteria tool to define indications for FT. In this study, we used the same criteria to evaluate the overall outcome of our first two patients after FT. PATIENTS AND METHODS: Preoperative analysis of our two bimaxillary FT patients was compared to the results at four and six years post-transplantation. The facial deficiency impact was divided into four categories: (1) anatomical regions, (2) facial functions (mimic muscles, sensation, oral functions, speech, breathing, periorbital functions), (3) esthetics, and (4) impact on health-related quality of life (HRQoL). Immunological status and complications were also evaluated. RESULTS: For both patients, near-normal anatomical restoration of almost all the facial regions (except the periorbital and intraoral regions) was achieved. The majority of the facial function parameters improved in both patients (patient 2 to a near-normal level). The esthetic score improved from severely disfigured to impaired (patient 1) and to near to normal (patient 2). Quality of life was severely lowered prior to FT and improved after FT but was still affected. Neither patient has experienced acute rejection episodes during follow-up. CONCLUSIONS: We conclude that our patients have benefitted from FT, and we have succeeded. Time will reveal whether we have achieved long-term success.

The four category systematic approach for selecting patients for face transplantation.

There is a need for a systematic approach to evaluate patients for potential face transplantation (FT). Ten patients with severe facial defects treated between 1995 and 2017 formed the study group. Data was collected from patient charts and clinical, radiological and laboratory examinations. Facial deficiencies were subdivided into four different categories: anatomical region (10 facial subunits), facial function, aesthetic defect (range 0-9-worst), and impact on health-related quality of life (HRQoL) (15D questionnaire, range 0-1). Immunological status and possible contraindications were also evaluated. Defect aetiology consisted of burns (4), ballistic injury (3), blunt injury (1), blast injury (1), and neurofibromatosis type I (1). All patients had central facial deficiencies and 6 patients had 8 to 10 injured facial subunits. All patients had at least partial loss of facial function. The mean aesthetic disfigurement score was 6.4. The median lowering of 15D score was -0.107. None were significantly sensitized although four patients had relative contraindications and one patient had an absolute contraindication for FT. Three patients with a severe overall facial deficiency were considered as potential FT candidates. We herein propose a comprehensive and systematic tool to evaluate potential candidates for FT. This approach includes assessment of 4 key categories: anatomical regions affected, facial function, aesthetics, and HRQoL.

Facial muscle reanimation by transcutaneous electrical stimulation for peripheral facial nerve palsy.

Reanimation of paralysed facial muscles by electrical stimulation has been studied extensively in animal models, but human studies in this field are largely lacking. Twenty-four subjects with a peripheral facial nerve palsy with a median duration of three years were enrolled. We studied activations of four facial muscles with electrical stimulation using surface electrodes. In subjects whose voluntary movement was severely impaired or completely absent, the electrical stimulation produced a movement that was greater in amplitude compared with the voluntary effort in 10 out of 18 subjects in the frontalis muscle, in 5 out of 14 subjects in the zygomaticus major muscle, and in 3 out of 8 subjects in the orbicularis oris muscle. The electrical stimulation produced a stronger blink in 8 subjects out of 22 compared with their spontaneous blinks. The stimulation could produce a better movement even in cases where the muscles were clinically completely paretic, sometimes also in palsies that were several years old, provided that the muscle was not totally denervated. Restoring the function of paralysed facial muscles by electrical stimulation has potential as a therapeutic option in cases where the muscle is clinically paretic but has reinnervation.

Patient-related reasons for late surgery cancellations in a plastic and reconstructive surgery department.

Late cancellations of scheduled operations cause direct and indirect costs for a hospital and economic and emotional stress for the patient. Previously, late cancellation rates for scheduled operations in plastic surgery have been shown to be attributable to patient-related causes in the majority of cases. In this retrospective study, we sought to examine specifically the patient-related reasons for the late cancellations in a plastic surgery operating theatre at Helsinki University Hospital in Finland from 2013 to 2014. We calculated latency between the date of decision for surgery and the scheduled operation day. In cases where the surgery was rescheduled and performed before 31 December 2015, the rescheduled waiting time latency was calculated. We aimed to improve our knowledge of the causes of late cancellations to further optimise the operating theatre efficiency and propose a strategic algorithm to avoid late cancellations During the study period, 327 (5.5%) of all the scheduled operations were recorded as late cancellations. Of these, 45.3% were because of patient-related issues. Acute infection, change in medical condition not noticed before and operation no longer necessary were by far the most common causes of cancellation, comprising 63.5%. Sixty-six per cent of patient-related cancelled operations were performed later, especially when the specific reason was patient's acute illness. Root-cause analysis shows that most of the underlying reasons for the cancellations can be attributed to a failure in communication. The majority of these cancellations were considered to be preventable, thus emphasising the importance of communication and skilful multi-professional planning of the operating theatre list.

The Helsinki Face Transplantation: Surgical aspects and 1-year outcome.

BACKGROUND: Since 2005, at least 38 facial transplantations have been performed worldwide. We herein describe the surgical technique and 1-year clinical outcome in Finland's first face transplant case. METHODS: A 34-year-old male who had a severe facial deformity following ballistic trauma in 1999 underwent facial transplantation at the Helsinki University Hospital on 8th February 2016. Three-dimensional (3D) technology was used to manufacture donor and recipient patient-specific osteotomy guides and a donor face mask. The facial transplant consisted of a Le Fort II maxilla, central mandible, lower ⅔ of the midface muscles, facial and neck skin, oral mucosa, anterior tongue and floor of mouth muscles, facial nerve (three bilateral branches), and bilateral hypoglossal and buccal nerves. RESULTS: At 1-year follow-up, there have thus far been no clinical or histological signs of rejection. The patient has a good aesthetic outcome with symmetrical restoration of the mobile central part of the face, with recovery of pain and light touch sensation to almost the entire facial skin and intraoral mucosa. Electromyography at 1 year has confirmed symmetrical muscle activity in the floor of the mouth and facial musculature, and the patient is able to produce spontaneous smile. Successful social and psychological outcome has also been observed. Postoperative complications requiring intervention included early (nasopalatinal fistula, submandibular sialocele, temporomandibular joint pain and transient type 2 diabetes) and late (intraoral wound and fungal infection, renal impairment and hypertension) complications. CONCLUSION: At 1 year, we report an overall good functional outcome in Finland's first face transplant.

Reconstruction of facial nerve after radical parotidectomy.

CONCLUSION: Most patients benefitted from immediate facial nerve grafting after radical parotidectomy. Even weak movement is valuable and can be augmented with secondary static operations. Post-operative radiotherapy does not seem to affect the final outcome of facial function. OBJECTIVES: During radical parotidectomy, the sacrifice of the facial nerve results in severe disfigurement of the face. Data on the principles and outcome of facial nerve reconstruction and reanimation after radical parotidectomy are limited and no consensus exists on the best practice. METHOD: This study retrospectively reviewed all patients having undergone radical parotidectomy and immediate facial nerve reconstruction with a free, non-vascularized nerve graft at the Helsinki University Hospital, Helsinki, Finland during the years 1990-2010. There were 31 patients (18 male; mean age = 54.7 years; range = 30-82) and 23 of them had a sufficient follow-up time. RESULTS: Facial nerve function recovery was seen in 18 (78%) of the 23 patients with a minimum of 2-year follow-up and adequate reporting available. Only slight facial movement was observed in five (22%), moderate or good movement in nine (39%), and excellent movement in four (17%) patients. Twenty-two (74%) patients received post-operative radiotherapy and 16 (70%) of them had some recovery of facial nerve function. Nineteen (61%) patients needed secondary static reanimation of the face.

Facial nerve reconstruction and facial disfigurement after radical parotidectomy.

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.

Union and bone resorption of free fibular flaps in mandibular reconstruction.

BACKGROUND: The purpose of this study was to evaluate bony union and resorption after free fibular flap reconstruction for mandibular reconstruction. METHODS: A total of 112 patients with composite resection and reconstruction with a fibular free flap were included. Computed tomography scan images taken after the reconstruction and approximately 1 year postoperatively were assessed to evaluate union (n = 60) and bone resorption (n = 24) of the neomandible. RESULTS: Most of the fibulas healed well (n = 34) and there was radiologic nonunion in 20% of the neomandibles at the time of evaluation (mean = 15 months). There was a statistically significant reduction in bone height in the native mandible (p = 0.02) and the anterior part of the fibular graft (p = 0.02). CONCLUSIONS: There was a statistically significant reduction in mandibular and fibular graft height. However, the bone resorption was clinically minimal. Sufficient maintenance of height and good bony union support the use of free fibular flap in mandibular reconstruction.

Second free flaps in head and neck reconstruction.

INTRODUCTION: Ablative surgery for head and neck cancer often results in defects that require free flap reconstruction. Improved survival after refined oncologic and adjuvant techniques has led to an increase in the number of patients undergoing a second free flap reconstruction. The objective of this study was to assess outcomes following a second free flap in head and neck reconstruction. MATERIALS AND METHODS: Following ablative defects in the head and neck, 1475 patients underwent reconstructive surgery over a period of 17 years. A second free flap for reconstruction was performed on 123 of these patients. In Group 1, 93 patients had a reconstruction for either tumour recurrence, second primary tumour or reconstructive complications (fractured plate, osteoradionecrosis, orocutaneous fistula). In Group 2, 30 patients had a second free flap following primary free flap reconstructive failure. RESULTS: Flap success for Group 1 patients was 86/90 (96%) compared to group 2 patients, 22/30 (73%) (p < 0.05). In Group 1, partial necrosis occurred in four patients whereas in Group 2, there was only one partial necrosis (NS; p > 0.05). CONCLUSION: A second free flap may be required for reconstruction of head and neck defects following complications of the initial reconstruction, presence of a second primary or tumour recurrence. Success rates for second free flap reconstructions were significantly lower in those patients with initial free flap failure.

Vascular endothelial growth factor and its receptors are expressed in human nerve grafts.

Vascularization and angiogenicity of human nonvascularized nerve grafts in the second stage of facial reanimation were studied. Immunohistochemistry for endothelial markers (CD-31) and vascular endothelial growth factor (VEGF) and its receptors Flt-1 and Flk-1 was performed on distal end biopsies from 35 cross-facial nerve grafts. In grafted nonvascularized nerve, density of vascular structures (also clearly immunopositive for VEGF and both receptors) showed a mean of 166 vessels (range 78 to 267) per unit area, corresponding to control values. In addition, VEGF was expressed in axons and perineural structures. In control samples, VEGF expression was low and occurred in the myelin sheath. In nerve grafts, expression of Flt-1 and Flk-1 (less intense) was seen in axons and perineural structures. A higher density of vessels was associated with lower VEGF expression (not significant). In short, expression of VEGF and its receptors is described in human nerve grafts and compared with basic histology and p75 nerve growth factor receptor expression of the nerve graft and functional outcome of patients.

P75 nerve growth factor receptor is expressed in regenerating human nerve grafts.

BACKGROUND: The purpose of this study was to elucidate the expression of p75 nerve growth factor receptor (p75NGFR) in human cross-facial nerve grafts and to compare the immunohistological findings with patient data and the functional outcome in facial reanimation. MATERIALS AND METHODS: The study comprised 37 sural nerve graft specimens. All of the patients had long-lasting complete facial paralysis and were operated on by the standard two-stage procedure involving cross-facial nerve grafts and microneurovascular muscle transfer. Nerve biopsies were taken 4 to 20 months (mean, 8 months) after the cross-facial nerve grafting. Immunohistochemistry for p75NGFR as well as for Schwann cells (S-100; Dako, Glostrup, Denmark) and for Neurofilament-200 (NF-200; Boehringer, Mannheim, Germany) was performed. RESULTS: In graft biopsies, the mean number of NF-200-positive axons amounted to 38% (range, 6-81%) of that in control samples. Further, regenerated axons were thinner than in control samples. Morphologically, the grafted nerves were characterized by fibrosis and invasion of inflammatory cells. A longer time between cross-facial nerve grafting and biopsy sampling correlated with a higher number of viable axons (NF-200) (P = 0.002). In all cases, expression of p75NGF receptor was clearly higher at the distal end of the grafted nerve. Expression of p75NGFR was lower in older than in younger patients (P = 0.003). A high expression of p75NGFR was often seen with better function of the transplanted muscle. CONCLUSION: Increased expression of p75NGFR in human nerve grafts was noted, especially in younger patients. We suggest that p75NGFR expression might be a contributing factor in a successful axonal regeneration and eventual recovery of muscle function.

Long-term adaptation of human microneurovascular muscle flaps to the paralyzed face: an immunohistochemical study.

The purpose of this study was to characterize microneurovascular (MNV) muscle transplants immunohistochemically up to 10 years after transfer. Histological data was related to long-term functional outcome. The study comprised 17 patients with a mean age of 41 years suffering from complete unilateral long-lasting facial paralysis. A two-stage procedure was performed between 1986 and 2001. The gracilis, latissimus dorsi, and serratus muscles were used in four, eight, and five patients, respectively. Eighteen biopsy samples were taken from MNV muscle grafts during secondary refinement procedures. In one patient, the tissue samples were collected at two different time points. Immunohistochemistry testing revealed muscle fiber type distribution (anti-myosin fast), proliferating satellite cells (Ki-67), and reinnervation (S-100). Muscle atrophy was assessed histomorphometrically. In a recent study, patient characteristics and the function of the flap were evaluated. Histological data were compared with clinical data and long-term functional outcomes of the patients. In biopsy samples taken 1-10 (mean 31 months) years after MNV muscle transfer, the mean muscle fiber diameter was 38 (range 14-70) microm, indicating a 40% decrease compared with control values. Muscle atrophy was not type-specific and the mean percentage of type II fibers was not altered. Individual variation was, however, considerable. Proliferative activity of satellite cells was seen in 60% of the samples but it tended to decline with an increase in follow-up time. All samples showed intramuscular reinnervation. In statistical analysis severe atrophy correlated with prolonged intraoperative ischemia (P=0.04). The good long-term functional outcome correlated with dominance of fast fibers in muscle grafts (P=0.03). Atrophy tended to be more pronounced in the serratus than in the other muscles (ns). In summary, despite dense muscle reinnervation, morphology of the muscle is not fully restored after muscle transfer. Ischemia time affects muscle morphology. Adaptation of the graft to fast-twitch muscle activity favors better mimic function. The proliferative activity of satellite cells declines with prolonged follow-up time.

Facial reanimation by transplantation of a microneurovascular muscle: long-term follow-up.

The two-stage operation for reanimation of long-standing facial paralysis by cross-facial nerve grafting and later free microneurovascular muscle transfer has been the treatment of choice for nearly 25 years. However, the functional outcome may be unpredictable. We therefore need to know more about the factors that influence the final result. We have recorded the long-term results of microneurovascular surgery in facial paralysis, and evaluated which factors influenced the functional outcome. Twenty-seven of 40 patients aged 7 to 65 years (mean 40) operated on at Helsinki University Hospital between 1986 and 2000 were available for interview and video recording. The gracilis, latissimus dorsi, and serratus anterior muscles were used for microneurovascular transfer in 11, 10, and 6 cases, respectively. The outcome of microneurovascular muscle transfer was graded on House's scale 1 to 6. The mean follow-up period was 8.5 years (range 2 to 15). Sixteen patients (59%) displayed only mild or moderate dysfunction (grades 2 to 3) after reconstruction. In 8 patients (30%) dysfunction was graded as moderately severe, and in 3 (11%) as severe. There was a correlation between final functional outcome and the follow-up time after microneurovascular facial reanimation. The longer the follow-up time after muscle transplantation the poorer the functional result (p = 0.003). Twenty-one patients (78%) considered that their quality of life was better or much better after facial reanimation. Patients' satisfaction correlated with a good functional result.
