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.

Validation of the Finnish FACE-Q for use in patients undergoing surgery for functional problems or malignancy.

The aim of this study was to produce a Finnish version of the FACE-Q scales Satisfaction with Forehead and Eyebrows, Adverse effects: Forehead, Eyebrows and Scalp, and Adverse effects: Cheeks, Lower face and Neck, and assess the performance of these scales and the Satisfaction with Facial Appearance, Satisfaction with Outcome and Appearance-related Psychosocial Distress in patients who had undergone surgery for functional problems or malignancy affecting the forehead or cheeks. The general health-related outcomes instrument 15 D was used as a reference. Patients who had undergone a frontal lift, a direct brow lift, a facelift or an excision of a facial tumor in Helsinki University Hospital plastic surgery department in 2009-2019 were identified. A postal survey study was conducted with 305 patients, of whom 135 (44%) responded. Diagnoses included facial nerve dysfunction (53%), brow ptosis (21%) and skin, mucosal or salivary gland tumor (20%). The FACE-Q scales displayed high internal consistency (Cronbach's alphas ≥0.80) and good reliability on repeat administration. The exploratory factor analysis revealed unifactorial influences for all scales except the Adverse effects: Forehead, Eyebrows and Scalp. Weak correlations with 15 D dimensions were detected. The FACE-Q scales evaluated here are suitable for use in patients with functional problems or malignancy.

Virtual 3D planning and prediction accuracy in two bimaxillary face transplantations in Helsinki.

BACKGROUND: The aim of this study was to describe the 3D planning process used in our two composite face transplantations and to analyze the accuracy of a virtual transplantation in predicting the end-result of face transplantation. METHODS: The study material consists of two bimaxillary composite face transplantations performed in the Helsinki University Hospital in 2016 and 2018. Computed tomography (CT) scans of the recipient and donor were used to define the osteotomy lines and perform the virtual face transplantation and to 3D print customized osteotomy guides for recipient and donor. Differences between cephalometric linear and angular measurements of the virtually simulated and the actual postoperative face transplantation were calculated. RESULTS: No changes to the planned osteotomy lines were needed during surgery. The differences in skeletal linear and angular measurements of the virtually simulated predictions and the actual postoperative face transplantations of the two patients varied between 0.1-5.6 mm and 0.7°-4°. The postoperative skeletal relationship between maxilla and mandible in both patients were almost identical in comparison to the predictions. CONCLUSIONS: 3D planning is feasible and provides close to accurate bone reconstruction in face transplantation. Preoperative virtual transplantation assists planning and improves the outcome in bimaxillary face transplantation.

Speech Characteristics and Oromyofunctional Outcomes in Two Bimaxillary Face Transplantation Patients in Helsinki.

OBJECTIVES/HYPOTHESIS: Facial functional restoration is one of the main goals in face transplantation. We report the oromyofacial function outcomes of two bimaxillary face transplantation (FT) patients in Helsinki. STUDY DESIGN: Outcome Study. METHODS: Two male patients, aged 34 and 59, had severe functional facial disabilities following self-inflicted gunshot injuries sustained to their mid and lower faces several years earlier. Both underwent tooth-bearing maxillomandibular face transplantation in 2016 and 2018. We collected data regarding speech, swallowing, sensory recovery, motor recovery, and olfaction prior to transplantation. Patient charts were reviewed from the follow-up period of 4 and 2 years, respectively. RESULTS: Speech intelligibility, acceptability, and articulation continued to improve during follow-up for both patients. Voice quality and resonance were mainly normal at last follow-up. Swallowing improved once lip occlusion was regained, with only minor aspiration evident on videofluorography. Both patients had significant improvement in facial mimic muscle function after FT. The first patient who only had buccal sensory nerves connected has only recovered protective facial sensation, whereas our second patient with buccal, infraorbital, and alveolar nerves connected has almost complete facial two-point discrimination. CONCLUSION: Both patients have regained satisfactory facial sensory and motor function. Sensory recovery seems to be faster and more precise if multiple sensory nerve coaptations are performed. Swallowing and speech have continued to improve over time although not reaching the level of the normal population. We demonstrate how speech-corrective surgery can safely be performed in a FT patient and can improve speech recovery. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:E2643-E2649, 2021.

Application of the FACE-Q rhinoplasty module in a mixed reconstructive and corrective rhinoplasty population in Finland.

The FACE-Q Rhinoplasty module is a patient-reported outcome instrument developed for the assessment of primarily aesthetic outcomes of rhinoplasty. The aim of our study was to produce a Finnish version of the instrument and validate it for use in patients undergoing nasal reconstruction as well as those treated with a rhinoplasty. Finnish versions of the FACE-Q scales Satisfaction with Nose, Satisfaction with Nostrils and Adverse Effects: Nose, were translated following established guidelines. Patients undergoing nasal resection, reconstruction or rhinoplasty in Helsinki University Hospital plastic surgery department in 2009-2019 were identified using theatre records. A total of 240 Finnish-speaking patients 18-85 years old were approached with a postal survey questionnaire. The questionnaire included the translated FACE-Q modules and those for Satisfaction with Facial Appearance, Appearance-Related Psychosocial Distress and Satisfaction with Outcome, as well as the general health-related quality of life instrument 15 D. The FACE-Q scales translated readily to Finnish. Eighty-three patients (35%) responded to the survey. Most FACE-Q scales performed well with high internal consistency (Cronbach's alphas 0.87-0.92) and repeatability. Only the Adverse Effects: Nose scale displayed poor consistency and a floor effect with 18% of the patients reporting no adverse outcomes. Answers to the Appearance-Related Psychosocial Distress scale were skewed towards no experienced stress. Answers to the other scales were normally distributed with weak correlation with 15 D dimensions. The Finnish translations of the FACE-Q Rhinoplasty scales perform well at assessing a diverse group of patients including those undergoing nasal reconstruction as well as those undergoing rhinoplasty.

The Helsinki approach to face transplantation.

AIM: We herein describe the establishment of the Helsinki Vascularized Composite Allotransplantation (VCA) program and its execution in the first two face transplant cases. METHODS & PATIENTS: The Helsinki VCA program initially required the fulfillment of legal, hospital, financial, and ethical requirements. Thereafter, the assembling of a multidisciplinary team commenced. A team of Plastic, maxillofacial and ENT surgeons comprise the facial VCA team. The protocol involves collaboration with the Solid Organ Transplant (SOT) team, transplant immunology, immunosuppression, microbiology, psychiatric evaluation, well-defined VCA indications and informed consent. Between 2011 and 2017 two patients were selected for transplantation. Both patients had a severe composite facial deformity involving the maxilla and mandible following earlier ballistic injury. RESULTS: Patient 1 was a 35 year-old male who underwent successful near total face transplantation in February 2016 and at 30 months he has a good aesthetic outcome with symmetrical restoration of the central face and good sensory and symmetrical motor functional outcomes. Patient 2 was a 58 year-old male who underwent full face transplantation in March 2018 and at 5 months he has recovered without major problems. CONCLUSION: A successful facial VCA program requires a well-prepared research protocol, experts from multiple specialties and careful patient selection. The establishment of the Helsinki VCA program required long and thorough planning and resulted in the first two Nordic face transplantation cases. This protocol now forms the platform (as a proof of concept) for other types of vascularized composite allotransplantations.

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.

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.

Effect of delayed autologous breast reconstruction on breast cancer recurrence and survival.

BACKGROUND: The goal of the present study was to evaluate the impact of delayed autologous breast reconstruction on disease relapse in breast cancer patients treated with mastectomy. MATERIAL AND METHODS: The study was based on 503 consecutive patients younger than 70 years of age who underwent mastectomy between January 2000 and December 2003. Overall, 391 (78 %) received mastectomy alone and 112 (22 %) underwent a delayed breast reconstruction. The median time from mastectomy to delayed breast reconstruction was 34 months. The median duration of follow-up was 102 months. RESULTS: There were no locoregional recurrences (LRR) in patients who underwent delayed reconstruction (0.0 %); 21 LRR developed in patients treated with mastectomy only (5.4 %), P = 0.011. Distant metastases occurred less frequently in the reconstruction group (12.5 %) than in the patients who underwent mastectomy alone (21.5 %); P = 0.0343. The 8-year breast cancer specific survival in the reconstruction group was 98.2 and 85.7 % for the mastectomy only group, P = 0.000. CONCLUSIONS: Delayed autologous breast reconstruction does not appear to adversely influence disease progression when compared to patients treated with mastectomy only.

The dermis graft: another autologous option for acute burn wound coverage.

BACKGROUND: Split-thickness skin autografts are the gold-standard in providing permanent acute wound closure in major burns. Split-thickness dermal grafts harvested from the same donor site may provide an additional autologous option for permanent acute coverage and increase the number of potential autologous donor sites. MATERIALS AND METHODS: We performed 16 dermis grafts (DG) harvested from the skin of the back in 9 consecutive burn patients. A control donor site consisted of an area of adjacent back skin from which a standard split-thickness skin graft was harvested. The mean age was 63 years (range 23-79 years). The mean initial burn size was 24% TBSA (range 2-40% TBSA). The size of the 16 DG recipient wound beds ranged from 20 to 180 cm2, with mean and median sizes of 62 and 45 cm2, respectively. RESULTS: Dermis graft take was complete in 15/16 cases. All grafts recorded >90% epithelialisation by 4 weeks. There was no significant difference in dermis graft and control donor site healing times (p value 0.05). CONCLUSION: Dermis grafts can provide an additional autologous option for permanent coverage in acute major burn wounds without increasing donor site size or morbidity.

Evolving practice of the Helsinki Skin Bank.

The purpose of this study is to review the management and running of the Helsinki Skin Bank between the years 2001 and 2008. Further aims were to assess the microbiological safety of the glycerol-preserved allograft skin and analyse its clinical use. The files of the Helsinki Skin Bank were reviewed for allograft skin harvested from organ donors between 2001 and 2008. Data on harvested skin area and microbiological culture results were collected. The patients receiving allograft were also identified and operation indications analysed. Allograft skin was collected from 115 donors, with a mean of 44,335 cm(2) per year. No skin batches were discarded. Microbiological cultures of the allograft skin batches were negative in 86 (75%) cases. Thirty-five donor skin batches were used in 69 operations. The most common indication was 'Biological dressing on partial-thickness burns', comprising 52% of cases. The cost per cm(2) was 0.81euro. The use of allograft skin in the Helsinki Skin Bank is microbiologically safe and continues to provide a versatile and useful treatment modality in many major burn cases with few observed complications. As compared with synthetically produced temporary dressings currently available, our allograft skin is also more economical.
