Long-term skeletal, cephalometric, and volumetric changes in two Helsinki bimaxillary face transplant patients.

Analysis of skeletal, cephalometric, and volumetric changes and occlusion during long-term follow-up was performed for two patients who underwent bimaxillary facial transplantation (FT). The study material consisted of the follow-up data of two bimaxillary composite FT performed in Helsinki University Hospital, one in 2016 and the other in 2018. Serial three-dimensional computed tomography scans obtained during follow-up (6 years for patient 1, 4 years for patient 2) were analyzed. The position of the maxilla remained stable in both patients. At 4 and 6 years, the changes in the anterior maxilla were ≤1 mm, while the anterior mandible had moved 2.6-4 mm anteriorly and the mandibular midline 0.4-3.7 mm to the left side. Patient 1 underwent re-osteosynthesis 4 months after transplantation due to mandibular non-union. Patient 2 had a sagittal mandibular osteotomy at 15 months after FT due to lateral crossbite and tension created by temporomandibular joint rotation. Thereafter both patients had a stable occlusion. A continuous bone volume reduction in the mandible was noticed in both patients (6% and 9% reduction of the transplanted volume). The volume of the transplanted maxilla decreased during the early postoperative period but increased back to the original transplanted volume during the follow-up.

Three-dimensional printing for restoration of the donor face: A new digital technique tested and used in the first facial allotransplantation patient in Finland.

BACKGROUND AND AIMS: Prosthetic mask restoration of the donor face is essential in current facial transplant protocols. The aim was to develop a new three-dimensional (3D) printing (additive manufacturing; AM) process for the production of a donor face mask that fulfilled the requirements for facial restoration after facial harvest. MATERIALS AND METHODS: A digital image of a single test person's face was obtained in a standardized setting and subjected to three different image processing techniques. These data were used for the 3D modeling and printing of a donor face mask. The process was also tested in a cadaver setting and ultimately used clinically in a donor patient after facial allograft harvest. RESULTS: and Conclusions: All the three developed and tested techniques enabled the 3D printing of a custom-made face mask in a timely manner that is almost an exact replica of the donor patient's face. This technique was successfully used in a facial allotransplantation donor patient.

Late results following flap reconstruction for chest wall recurrent breast cancer.

INTRODUCTION: Locally extensive recurrent breast cancer usually portends a poor prognosis but certain cases can be treated surgically by wide soft-tissue resection as well as full-thickness chest wall resection (FTCWR). The resulting defect usually necessitates immediate flap coverage. The aim of this study was to assess local control, morbidity, choice of flap reconstruction, patient selection and overall long-term survival following surgical salvage of patients with chest wall recurrent breast cancer. MATERIALS AND METHODS: Forty patients were treated with wide soft-tissue resection and immediate flap reconstruction from 1984 to 2011 in a single institution. Demographic, treatment and mortality data were obtained from patients' files. RESULTS: Mean age at surgery was 54 years. FTCWR was performed in 19 cases including three extended forequarter amputations. Chest wall stabilisation involved a synthetic mesh in 12 patients, fascia lata in two patients, free rib grafts in one patient and synthetic mesh and free rib graft in one patient. Soft-tissue reconstruction consisted of microvascular free flaps in seven patients and pedicled flaps in 33 patients. In-hospital mortality was 0%, 30-day mortality was 5%; there were two re-operations, six minor wound complications and one pulmonary embolism. There were no flap losses. In patients operated on with curative intent (n=31) median disease-free interval was 31 months and median survival was 52 months. CONCLUSIONS: In selected cases wide resections for extensive chest wall recurrent breast cancer can result in reasonable local control and survival. Several flap options exist for soft-tissue reconstruction.

Surgical management of radiation-associated cutaneous breast angiosarcoma.

The purpose of this study was to investigate the surgical management of radiation-associated cutaneous breast angiosarcoma with an emphasis on surgical margins and choice of reconstruction. Nine cases of angiosarcoma were identified in patients earlier treated with radiotherapy for breast cancer. Breast angiosarcoma was diagnosed a median of 5.25 years following radiotherapy. Median age at diagnosis was 60 years. Surgical treatment consisted of radical mastectomy (four cases), simple mastectomy (two cases) and wide local excision (three cases). Defect reconstruction involved three latissimus dorsi flap reconstructions and four skin grafts. Clear histological margins were achieved in all cases. Median follow-up was 81 months. Six patients were alive and disease-free at the end of the study period. Aggressive surgical resection with wide margins is essential to reduce local recurrence and improve survival.

Skin-sparing mastectomy and immediate breast reconstruction in the management of locally recurrent breast cancer.

AIM: To investigate whether skin-sparing mastectomy (SSM) and immediate breast reconstruction (IBR) is a possible treatment option in selected cases of locally recurrent breast cancer after previous breast-conserving therapy (BCT). MATERIAL AND METHODS: Sixty consecutive patients were treated by SSM and IBR between 1995 and 2008 for ipsilateral breast tumour recurrence (IBTR). Selection criteria consisted of: IBTR <3 cm size, not infiltrating skin or chest wall, primarily node negative, recurrence >3 years after primary operation, and no metastases. Patient records were analysed retrospectively and follow-up data on patient outcome included. RESULTS: The reconstruction method consisted of 40 free abdominal flaps, 18 latissimus dorsi (LD) flaps with or without an implant, and two cases of implant only. Twenty-three patients received adjuvant oncological therapy. During median follow-up of 66 months, 11 patients (18%) developed disease relapse, including 6 (10%) local re-recurrences. CONCLUSION: IBR is a possible treatment option for patients who develop local recurrence following earlier BCT. Our local re-recurrence rate of 10% compares well with that following salvage mastectomy for IBTR. Of patients, 43% did not actually meet our selection criteria but yet appeared to fare well in terms of outcome. Therefore we should re-evaluate our selection criteria.

Resuscitation tables: a useful tool in calculating pre-burns unit fluid requirements.

BACKGROUND: There is considerable variation in the standard of initial burn management, particularly burn surface area assessment and application of resuscitation formulae. Early aggressive management of major burns improves survival. Internationally, the Parkland formula employing lactated Ringer's solution is used for fluid resuscitation. This study aimed to assess whether Parkland fluid resuscitation tables could improve the accuracy of initial fluid requirement calculations. METHODS: The burn size had first to be determined for an adult and a child using a preshaded Lund and Browder chart. Fluid requirements then had to be calculated using the conventional Parkland formula. The burn size had to be similarly calculated for two further cases and fluid requirements calculated using resuscitation tables. The study had a sample size of 50, consisting of plastic surgery trainees, anaesthetists and burn nurse specialists. RESULTS: All the participants found the resuscitation tables to be quicker and easier to use. The burn size was correctly calculated in 72% of cases. Fluid resuscitation requirements were correct in only 55% when using the Parkland formula. The use of resuscitation tables improved the accuracy in calculating fluid requirements to 75%. CONCLUSIONS: The use of Parkland fluid resuscitation tables can improve accuracy and ease of calculation of fluid resuscitation requirements.

Home oxygen therapy and cigarette smoking: a dangerous practice.

Oxygen as a therapeutic agent is an important form of home therapy for hypoxic chronic obstructive pulmonary disease (COPD) and improved survival has been demonstrated in hypoxic COPD patients receiving continuous oxygen. However, some patients, despite dissuasion, continue to smoke and we describe the case of a patient on home oxygen who sustained a partial-thickness facial flash burn whilst engaged in this habit. A review is made of the literature, as also a comparison of all discovered cases of burns in home oxygen users, followed by a discussion of the implications of this potentially hazardous form of therapy.
