International consensus recommendations on face transplantation: A 2-step Delphi study.

Face transplantation is a viable reconstructive approach for severe craniofacial defects. Despite the evolution witnessed in the field, ethical aspects, clinical and psychosocial implications, public perception, and economic sustainability remain the subject of debate and unanswered questions. Furthermore, poor data reporting and sharing, the absence of standardized metrics for outcome evaluation, and the lack of consensus definitions of success and failure have hampered the development of a "transplantation culture" on a global scale. We completed a 2-round online modified Delphi process with 35 international face transplant stakeholders, including surgeons, clinicians, psychologists, psychiatrists, ethicists, policymakers, and researchers, with a representation of 10 of the 19 face transplant teams that had already performed the procedure and 73% of face transplants. Themes addressed included patient assessment and selection, indications, social support networks, clinical framework, surgical considerations, data on patient progress and outcomes, definitions of success and failure, public image and perception, and financial sustainability. The presented recommendations are the product of a shared commitment of face transplant teams to foster the development of face transplantation and are aimed at providing a gold standard of practice and policy.

Enhanced recovery after surgery (ERAS) protocol improves patient outcomes in free flap surgery for head and neck cancer.

BACKGROUND: In recent years, enhanced recovery after surgery (ERAS) guidelines have been developed to optimize pre-, intra-, and postoperative care of surgical oncology patients. The aim of this study was to compare management outcome of patients undergoing head and neck cancer (HNC) surgery with free flap reconstruction at our institution before and after the implementation of the ERAS guidelines. METHODS: This retrospective study comprised 283 patients undergoing HNC surgery with free flap reconstruction between 2013 and 2020. Patients operated before and after the implementation of the ERAS protocol in October 2017 formed the pre-ERAS group (n = 169), and ERAS group (n = 114), respectively. RESULTS: In the pre-ERAS group the mean length of stay (LOS) and intensive care unit length of the stay (ICU-LOS) were 20 days (range 7-79) and 6 days (range 1-32), and in the ERAS group 13 days (range 3-70) and 5 days (range 1-24), respectively. Both LOS (p < 0.001) and ICU-LOS (p = 0.042) were significantly reduced in the ERAS group compared to the pre-ERAS group. There were significantly fewer medical complications in the ERAS group (p < 0.003). No difference was found between the study groups in the surgical complication rate or in the 30-day or 6-month mortality rate after surgery. CONCLUSIONS: We found reduced LOS, ICU-LOS, and medical complication rate, but no effect on the surgical complication rate after implementation of the ERAS guidelines, which supports their use in major HNC surgery.

Costs of oropharyngeal squamous cell cancer treatment in Finland.

BACKGROUND: Oropharyngeal squamous cell carcinoma (OPSCC) can be treated with definitive (chemo)radiotherapy ((C)RT) or primary surgical treatment (PST) with or without postoperative oncologic treatment. The prognosis of OPSCC does not essentially depend on the treatment modality, which allows to consider secondary decision-making aspects such as treatment costs when recommending an individual treatment modality. We attempted to analyze the costs associated with definitive (C)RT and PST in the treatment of OPSCC in Finland. MATERIALS AND METHODS: We included 73 patients diagnosed with OPSCC at the Helsinki University Hospital (HUS) (Helsinki, Finland) in 2019 and 2020. Treatment costs were defined as the costs incurred in the specialized medical care during the first 12 months after the diagnosis was established. RESULTS: Definitive RT and definitive CRT were on a 1-year horizon associated with median costs of approximately 10 700€ and 13 300€, respectively; while, the median costs of PST equaled about 40 600€. The costs of definitive (C)RT mostly consisted of the costs of (chemo)radiotherapy sessions; while, the operating room costs and the costs of intensive care and stay on a ward drove the costs of PST. CONCLUSIONS: PST is associated with 2-3 times higher median costs than definitive (C)RT in Finland. The finding differs from the results previously reported in North America, which is related, e.g., to differences in the treatment practices as well as in the regulation of the health care systems.

The Second Helsinki Face Transplantation and the World Experience of Revision Surgery During the First Posttransplantation Year.

INTRODUCTION: We conducted a review of all surgical interventions performed during the first postoperative year in published face transplantation (FT) cases. In addition, we herein present our second FT patient, a full-face composite FT with an emphasis on surgical revisions after transplantation. MATERIALS AND METHODS: A literature review was conducted and resulted in 376 publications of which 33 included reference to surgical interventions during the first post-FT year. For our second FT patient, a thorough review of all medical records was performed. RESULTS: Among the first 41 FTs, 32 FT patients had reports with reference to corrective surgery during the first year (22 composite and 10 soft-tissue FTs). Soft-tissue FTs had a median of 2 procedures (range, 1-8 procedures), and composite FTs, 3 procedures per patient (range, 1-9 procedures). Nearly all early interventions (<1 month) were performed in composite FT patients (anastomotic occlusion, hematoma, sialocele, palatinal dehiscence). The most common late interventions were scar corrections, tissue suspensions, periorbital corrections, osseal and dental procedures, and interventions for palatinal dehiscence and sialocele. Our second FT patient has recovered well and has undergone 3 surgical interventions during the first year. CONCLUSIONS: Surgical interventions are very common during the first postoperative year after FT, and composite FTs are more prone to complications necessitating surgical intervention than soft-tissue FTs. There is a wide variety of complications reflecting the heterogeneity of FT allografts. Corrective surgery in FT patients appears safe with only a few reported complications.

Perioperative Dexamethasone Is Associated With Higher Short-Term Mortality in Reconstructive Head and Neck Cancer Surgery.

PURPOSE: Studies of the effects of perioperative dexamethasone (DEX) during oncologic surgery are scarce. The first aim of the present study was to clarify whether perioperative DEX affects the short-term mortality in patients with head and neck cancer (HNC). The second aim was to analyze the causes of death and predictors affecting long-term mortality. PATIENTS AND METHODS: The present prospective, double-blind randomized, controlled study included patients with HNC who had undergone microvascular reconstruction from 2008 through 2013. The patients were randomized into 2 groups: the receipt of perioperative DEX for 3 days (study group) or no DEX (control group). The patients' data and cause of death were registered until the end of 2017. The primary cause of death was used in the analyses. RESULTS: A total of 93 patients were included in the present study: 51 in the DEX group (study group) and 42 in the NON-DEX group (control group). Altogether 38 patients died during a median follow-up period of 5.3 years. During the first year, more deaths had occurred in the DEX group than in the NON-DEX group: at 1 month, 4% versus 0%; at 6 months, 14% versus 0%; and at 12 months, 22% versus 5% (P = .043). The overall survival rate for all patients was 59%. HNC was the primary cause of death for most of the patients who died. On univariate analysis, the deceased patients had more advanced disease (higher T classification, P = .002; higher stage, P = .008), a greater need for a gastrostoma (P = .002), more often received postoperative chemotherapy (P = .005), and more often had locoregional (P = .025) or distal (P < .001) metastases. In the multivariate Cox model, the most important long-term predictors of death were the presence of distant metastases (P < .001), a Charlson comorbidity index (CCI) of 5 to 9 (P < .001), and the use of perioperative DEX (P = .004). CONCLUSIONS: The use of perioperative DEX was associated with higher short-term mortality after reconstructive HNC surgery. The most important long-term predictors of death were the receipt of DEX, the presence of distant metastases, and a CCI of 5 to 9. These findings do not encourage the routine use of perioperative DEX for these patients.

Total laryngopharyngectomy with circumferential reconstruction: Helsinki institutional study.

PURPOSE: Surgical complications after total laryngopharyngectomy (TLP) are common, reconstruction is challenging, and patients often lose their ability to swallow and speak. To evaluate these aspects, we analysed outcome after TLP. METHODS: We reviewed all patients who underwent TLP and subsequent circumferential pharyngeal reconstruction through 2004-2017 at the Helsinki University Hospital. RESULTS: For the 26 eligible patients, TLP was the primary treatment for 11 and salvage surgery for 15, followed by reconstruction with free flaps in 22 patients and pedicled flaps in 4. An early (≤ 30 days) pharyngocutaneous fistula developed in seven patients (27%; median time 13 days; range 6-26), and a late (> 30 days) fistula in five patients (19%; median time 370 days; range 46-785). In addition, ten patients (39%) developed an oesophageal stricture. Four patients (15%) resumed full oral feeding. A speech prosthesis was inserted for 15 patients (58%) and most of them could produce intelligible speech. We found acceptable survival figures for patients undergoing TLP both as a primary treatment and as salvage procedure: the overall survival at 1 year was 82% and 67%, and at 5 years 33% and 27%, respectively. Disease-specific survival at 1 year was 90% and 70%, and that at 5 years was 45% and 43%, respectively. CONCLUSIONS: Despite fair survival, TLP carries a high risk for postoperative complications with limited functional outcome, thus necessitating cautious patient selection and surgical experience.

More Harm Than Benefit of Perioperative Dexamethasone on Recovery Following Reconstructive Head and Neck Cancer Surgery: A Prospective Double-Blind Randomized Trial.

PURPOSE: Prospective studies on the effect of dexamethasone after microvascular reconstructive head and neck surgery are sparse despite the widespread use of dexamethasone in this setting. The aim of this study was to clarify whether perioperative use of dexamethasone would improve the quality and speed of recovery. The authors hypothesized that dexamethasone would enhance recovery and diminish pain and nausea. MATERIALS AND METHODS: Ninety-three patients with oropharyngeal cancer and microvascular reconstruction were included in this prospective double-blinded randomized controlled trial. Patients in the study group (n = 51) received dexamethasone 60 mg over 3 perioperative days; 42 patients did not receive dexamethasone and served as controls. Patient rehabilitation, postoperative opioid and insulin consumption, postoperative nausea and vomiting (PONV), and C-reactive protein (CRP), leukocyte, and lactate levels were recorded. RESULTS: There was significantly less pain in the study group (P = .030) and the total oxycodone dose for 5 days postoperatively was lower (P = .040). Dexamethasone did not significantly lessen PONV for 5 days postoperatively (P > .05). There were no differences between groups in intensive care unit or hospital stay or in other clinical measures of recovery. Patients receiving dexamethasone required significantly more insulin compared with patients in the control group (P < .001). Lactate and leukocyte levels were significantly higher (P < .001) and CRP levels were significantly lower in the study group. CONCLUSION: The only benefit of perioperative dexamethasone use was lower total oxycodone dose; however, the disadvantages were greater. Because dexamethasone can have adverse effects on the postoperative course, routine use of dexamethasone as a pain or nausea medication during reconstructive head and neck cancer surgery is not recommended.

Olfactory and gustatory functions after free flap reconstruction and radiotherapy for oral and pharyngeal cancer: a prospective follow-up study.

BACKGROUND: The senses of smell and taste can be adversely affected by both tumour- and treatment-related factors amongst head and neck cancer patients. The consequences may negatively impact nutritional status as well as quality of life in this patient population. PATIENTS AND METHODS: This prospective longitudinal follow-up study is consisted of 44 patients treated for oral cavity, oropharyngeal or hypopharyngeal cancer with tumour resection and microvascular free tissue transfer reconstruction at the Helsinki University Hospital, Helsinki, Finland. Thirty-nine (89%) of them also received radiotherapy. The senses of smell (odour detection, identification and threshold test) and taste (electrogustometry) and quality of life (UW-QOL) were evaluated preoperatively, and at 6 weeks, 3 months, 6 months and 12 months, postoperatively. RESULTS: There were higher scores in the odour detection values in the 6-week and 3-month tests compared with preoperative values for the tumour side. Other detection scores did not differ statistically from the preoperative values neither in the tumour nor the contralateral side. However, in the odour identification test, all posttreatment values were statistically significantly higher than pretreatment ones. In the olfactory threshold test, no statistically significant differences were found between pre- and posttreatment values. Electrogustometry values for the taste on the tumour side were statistically significantly impaired at 6 weeks (p < 0.05) and at 3 months (p < 0.01) compared with the pretreatment results. They were also impaired at 6 months and at 12 months, although the differences were not statistically significant. The quality of life was impaired after treatment in this patient series. However, the correlation between quality of life and sense of taste was found only at one time point (3 months) and only with contralateral side measurements. CONCLUSIONS: We conclude that in oral and pharyngeal cancer patients the postoperative taste problems are related to the impairment on the taste sensation in the tongue but not with the sense of smell. Moreover, the impairment in the quality of life is not clearly related to the impaired sense of taste.

Total or subtotal glossectomy with laryngeal preservation: a national study of 29 patients.

Total glossectomy remains a controversial procedure as it often leads to notorious sequalae in swallowing and speaking functions. Disease entities indicating total glossectomy tend to have poor prognosis. We evaluated whether this type of surgery can be concidered justified based on our national series. We reviewed all total and subtotal glossectomies with laryngeal preservation performed in Finland between 2005 and 2014 in terms of overall survival (OS), disease-specific survival (DSS), locoregional control (LRC), and functional outcome as assessed by gastric tube or tracheostomy dependence and ability to produce intelligible speech. Of the 29 eligible patients, 15 had undergone total and 14 subtotal glossectomy with curative intent. In eight patients, total/subtotal glossectomy was performed as salvage procedure after the previous treatment. One-year estimates for OS, DSS, and LRC were 48, 59, and 66%, and corresponding 3-year estimates were 31, 46, and 46%, respectively. The gastrostomy and tracheostomy dependence rates at 1 year after operation were 77 and 15%, respectively. Fifty-nine percent of the patients were assessed to be able to communicate verbally. As in most other published studies, we found unsatisfactory survival figures after subtotal or total glossectomy and most patients remained dependent on gastrostomy tube. This surgery is, however, presumably the best and often only chance for cure in a selective patient population, and according to our opinion, it is indicated as a primary or salvage treatment provided that the reconstruction is planned optimally to guarantee a reasonable quality of life after surgery.

More than just the helix: A series of free flaps from the ear.

AIM: We herein present our experience using free flaps harvested from the ear region in facial, nasal and intraoral reconstruction. PATIENTS AND METHODS: Between 2011 and 2016, 19 patients underwent reconstruction using 20 free flaps from the ear region based on the superficial temporal vessels. There were 10 males and 9 females with a mean age of 57 years. Defect aetiology consisted of post-tumour ablation (n = 15), trauma (n = 2) and burn scar (n = 2). Defect location involved the nose (n = 13), floor of mouth (n = 3), tongue (n = 1), lower eyelid (n = 1), and lower lip (n = 1). RESULTS: Twelve helical, seven temporal artery posterior auricular skin (TAPAS), and one hemiauricular flap were performed. One patient required venous re-anastomosis but complete flap necrosis eventually occurred. This patient later underwent successful contralateral helix flap reconstruction. Overall flap survival was 95%. Follow-up ranged from 12 to 69 months. A moderate to excellent aesthetic and functional outcome was achieved in all cases, but most (13/19) required later minor refinement surgery. CONCLUSION: As a versatile source of free flap options, the ear can provide more than just the helix.

A Comparison of Bone Resorption Over Time: An Analysis of the Free Scapular, Iliac Crest, and Fibular Microvascular Flaps in Mandibular Reconstruction.

PURPOSE: The aim of the present study was to compare the resorption of the bone in the free scapular, free iliac crest, and free fibular microvascular flaps in mandibular reconstruction over time. PATIENTS AND METHODS: In the present retrospective study, we analyzed 186 consecutive patients with scapular, fibular, or deep circumflex iliac artery (DCIA) osseous free microvascular flaps in mandibular reconstruction. We followed up the patients clinically and using multislice computed tomography (MSCT) with volume analyses of the bone. The volume of the bone was analyzed against time. RESULTS: A total of 38 patients fulfilled the study criteria. Resorption of the osseous flaps was found to continue for several years. At 2 years, the volume loss was 14% for the scapula, 3% for the DCIA, and 1% for the fibula. Three-dimensional (3D) volume analysis of the MSCT scans showed more resorption than 2-dimensional analyses of the radiographs. Postoperative radiation therapy, patient age, and patient gender did not correlate with bone resorption. CONCLUSIONS: After microvascular mandibular reconstruction, the volume reduction over time is the least in the fibula and the greatest in scapula, with that of the DCIA in between. The volume reduction continues for several years in all of these. For assessment of the volume reduction of osseal reconstruction, a 3D volume analysis is more reliable than height by width measurements.

Free temporal artery posterior auricular skin (TAPAS) flap: A new option in facial and intra-oral reconstruction.

BACKGROUND: There is a limited availability of suitable microvascular free flap options for the reconstruction of small to medium-sized facial and intraoral defects. The purpose of this report is to present a new free temporal artery based posterior auricular skin (TAPAS) flap in facial and intraoral reconstruction. PATIENTS AND METHODS: Four patients were deemed suitable for TAPAS flap reconstruction and consisted of two males and two females with a mean age of 43 years (range 22-66). Defect aetiology and location comprised of post-traumatic lower eyelid scarring, late lower lip scarring post tumour resection, and floor of mouth and tongue defects following tumour resection. The dimensions of the resultant defects ranged from 25 × 50 mm (smallest) to 40 × 70 mm (largest). All patients underwent microvascular reconstruction using a free fasciocutaneous TAPAS flap raised from the retroauricular region based on the superficial temporal vessels. RESULTS: The maximal pedicle length was 60 mm and the maximum flap size measured 40 mm by 70 mm. The latter patient required skin grafting of the postauricular donor site. Postoperatively, there was one case of mild transient venous congestion that spontaneously resolved after 2 days and one case of minor partial flap dehiscence that required re-suturing. Follow-up time ranged from 6 to 14 months. Overall, all flaps survived with good aesthetic and functional outcome. CONCLUSION: The TAPAS flap is a small flap with exceptional qualities and may be a useful addition to the armamentarium of free flaps in facial and oral reconstructions. © 2016 Wiley Periodicals, Inc.

Evolution of Head and Neck Microvascular Reconstructive Strategy at an Academic Centre: An 18-Year Review.

Background A remarkable development through the evolution of free flap techniques has led to the modern reconstructive head and neck surgery. This study aimed to review experiences from head and neck free-flap reconstructions performed at our institution over an 18-year period. Methods Between 1995 and 2012, 594 free-flap operations were performed on 541 head and neck patients at the Department of Plastic Surgery, Helsinki University Hospital, Finland. We retrospectively recorded hospital chart data regarding patient demographics, tumor characteristics, surgical treatment, and outcome. Results The mean age of patients increased from 53 years (1995-2000) to 56 (2007-2012), while the gender distribution remained constant (60% males). The most commonly used flap type between 1995 and 2000 was radial forearm flap (50%), while during the periods of 2001 through 2006 and 2007 through 2012 the anterolateral thigh flap was the most common method (42 and 36%, respectively). The number of different flap types and flap combinations increased during these periods (15 flap types during 1995 through 2000; 17 flap types during 2001 through 2006; and 24 flap types during 2007 through 2012). Despite a wider range of flap options used during the period 2001 through 2012, the overall flap survival rate (97%) remained constant. The prevalence of surgical complications decreased from 26% (2001 through 2006) to 21% (2007 through 2012). Conclusions During the study period, the number of flap types increased and reconstructions became more individualized. The overall surgical complication rate decreased although the mean age of patients increased.

Submental Artery Flap with Sentinel Lymph Node Biopsy in the Reconstruction of Oral Cancer.

BACKGROUND: Microvascular free flaps form the gold standard for reconstruction of defects after intraoral cancer surgery, but not all patients are suitable candidates for microsurgery. The submental artery flap is an alternative to free tissue transfer especially in patients who do not tolerate extensive operations due to major comorbidities. However, in metastatic neck disease, this option has not been recommended due to theoretical intraoral transfer of cancer cells. The aim of this study was to consider the indications and benefits of the submental artery perforator flap in patients with intraoral cancer. METHODS: Ten patients with early (N = 2) or locally advanced (N = 8) intraoral cancer, who were not candidates for free tissue transfer because of major comorbidities, were managed with tumor resection and coverage of the defect with the submental artery flap. The minimum follow-up time for all patients was 6 years. RESULTS: The average defect size was 5 × 9 cm. Two patients developed major complications and one of them had a flap loss. Sentinel lymph node biopsy was used in three cases to rule out positive neck disease close to the flap pedicle. During the follow-up time 6 out of 10 patients had a local recurrence and there were no appearances of metastatic neck disease. CONCLUSION: The submental artery flap is an alternative option to intraoral microvascular reconstruction in patients with major comorbidities. Sentinel lymph node biopsy can be used as an adjunct to enhance oncological safety.

Paraumbilical perforator flap for reconstruction of the external auditory meatus: A case report.

We herein present a technique of using the umbilical stalk for reconstruction of the external auditory meatus. A 49-year-old female presented with locally aggressive melanoma affecting her mastoid region. She underwent radical excision including the skin and soft tissues around the external ear with simultaneous lymph node clearance. The resultant defect measured 15 cm × 8 cm in diameter and was 2.5 cm deep. This was reconstructed with a similarly sized microvascular paraumbilical perforator flap that included the umbilical stalk. In the post-operative course there was complete flap survival but a prolonged wound dehiscence near the auditory meatus that required revision surgery. At 15-months follow-up, the patient was melanoma-free and the auditory meatus was patent. Hearing was also preserved. The umbilical stalk is one of the few skin covered tubed structures in the human body that may be used without major donor morbidity to "replace like with like," the auditory channel.

The pedicled latissimus dorsi flap in head and neck reconstruction: an old method revisited.

In head and neck cancer patients with significant comorbidities, the reconstructive options are limited, and there is a need for a safe alternative for microvascular flaps without compromising flap size. During the study period, 331 head and neck cancer patients were reconstructed with microvascular tissue flaps. Ten patients requiring large resections were considered to have high risks for long surgery and to be poor candidates for free tissue transfer and thus were reconstructed with a subpectorally tunneled pedicled latissimus dorsi (SP-LD) flap. The flap was raised simultaneously with the tumor resection and tunneled to the head and neck region. The flap was used for reconstruction of oral, mandibular, pharyngeal, or neck defects. Median follow-up was 3.6 years. Median duration of surgery was 7 hours and 17 minutes, and total hospital stay was 20 days. During the follow-up, four patients died of their disease and one from another cause (median of 329 days). We were able to perform large tumor resections with a curative intent and reconstruct major defects in high-risk head and neck cancer patients with a SP-LD flap. It possesses many of the characteristics of a free flap with the benefits of a shorter operation time and less perioperative risk.

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.

Facial Expression after Face Transplant: An International Face Transplant Cohort Comparison.

BACKGROUND: Assessment of motor function restoration following face transplant (FT) is difficult, as standardized, bilateral tests are lacking. This study aims to bolster support for software-based analysis through international collaboration. METHODS: FaceReader (Noldus, Wageningen, The Netherlands), a facial expression analysis software, was used to analyze posttransplant videos of eight FT patients from Boston, Massachusetts (range, 1 to 9 years after transplant), two FT patients from Helsinki, Finland (range, 3 to 4 years after transplant), and three FT patients from Antalya, Turkey (range, 6.5 to 8.5 years after transplant). Age-matched healthy controls from respective countries had no history of prior facial procedures. Videos contained patients and controls performing facial expressions evaluated by software analysis using the Facial Action Coding System. Facial movements were assigned intensity score values between 0 (absent) and 1 (fully present). Maximum values were compared with respective healthy controls to calculate percentage restoration. RESULTS: Of 13 FT patients, eight patients were full FT, five patients were partial FT, and two patients were female patients. Compared with healthy controls, the median restoration of motor function was 36.9% (interquartile range, 28.8% to 52.9%) for all patients with FT ( P = 0.151). The median restoration of smile was 37.2% (interquartile range, 31.5% to 52.7%) for all patients with FT ( P = 0.065). When facial nerve coaptation was performed at the distal branch level, average motor function restoration was 42.7% ± 3.61% compared with 27.9% ± 6.71% at the proximal trunk coaptation level ( P = 0.032). Use of interpositional nerve grafts had no influence on motor outcomes. CONCLUSIONS: Software-based analysis is suitable to assess motor function after FT. International collaboration strengthens outcome data for FT. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
