Facial transplantation: history and update.

BACKGROUND: Composite tissue allografting (CTA) represents the essence of reconstructive surgery, combining principles of solid organ transplantation (SOT) and modern plastic surgery techniques. The purpose of this article is to give a review of the history of facial CTA and an update of the cases that have been operated so far worldwide. METHODS: A systematic review of the medical literature was performed. Ten relevant publications were selected and analyzed for clinical data of the patients, surgical aspects of transplantation, complications and outcome. RESULTS: The past 9 years, 31 face transplants have been performed worldwide. The main indication was posttraumatic deformity. In all cases standard triple drug immunosuppression as used in SOT was successfully used and at least 1 period of acute rejection was seen in all patients, controllable with conventional immunosuppressive regimens. Overall functional outcomes are good and satisfaction rate is high, surpassing initial expectations. The main complications are opportunistic infections; 4 deaths occurred. CONCLUSIONS: Facial CTA is a life changing procedure and has led to new treatment options for patients with complex, devastating and otherwise unreconstructable facial deformities to restore appearance and overall wellbeing in a single operation. The key to success lies in the selection of the appropriate patient, who is stable, well-motivated and therapy compliant. Thorough screening and follow-up by a multidisciplinary team, well prepared surgical approach and intensive, early rehabilitation are all crucial factors for minimizing complications and a safe and rapid recovery.

The role of the internal mammary vessels as recipient vessels in secondary and tertiary head and neck reconstruction.

BACKGROUND: Successful microsurgical free tissue transfer for head and neck reconstruction highly depends on the quality of the recipient vessels. In most cases, vessels near the site of resection are available; however, when the bilateral vascular network in the neck is compromised or inaccessible due to prior surgery and/or irradiation, alternatives have to be sought. METHODS: Secondary or tertiary head and neck reconstruction was performed using the internal mammary vessels (IMVs) as recipient vessels in seven patients who had undergone previous neck dissection and radiation therapy. Indications were: tracheal-oesophageal fistula or stenosis (n = 4), oesophageal-cutaneous fistula (n = 1), saliva fistula (n = 1) and oral cancer (n = 1). Free flaps used for reconstruction were radial forearm flap (FRFF) (n = 5), anterolateral thigh flap (ALT) (n = 3) and transverse rectus abdominis myocutaneous flap (TRAM) (n = 1). Within two patients an additional ALT flap was necessary for soft-tissue coverage and resurfacing of the neck. The IMVs were separately exposed in a standard fashion over the second or third rib. The pedicle of the flap was anastomosed anterograde and end-to-end to the recipient vessels in all cases. Mean pedicle length was 14.3 cm (11-20 cm), with a mean distance of 9.8 cm (7-13 cm) between the resection and recipient vessel site. RESULTS: All patients were tumour free at time of re-operation and no sign of radiation injury was observed in the recipient vessels. All flaps survived and all patients healed without major complications. Mean follow-up time was 18 months. Four patients died of local recurrence or distant metastases during follow-up. CONCLUSION: In the vessel-depleted neck, the IMVs are a reliable and easy accessible recipient area for microsurgical reconstruction of the head and neck. Surgical management and technique refinements for dissection of the vessels are discussed. In combination with free flaps with a long pedicle, especially perforator flaps, vein grafts are unnecessary and microsurgery can safely be performed outside the zone of injury.

Pilomatricoma in children: common but often misdiagnosed.

A pilomatricoma, also known as pilomatrixoma or calcifying epithelioma of Malherbe, is a benign skin tumor arising from the hair follicle matrix. This tumor is common in children and young adults, especially in the head and neck region. However, pilomatricomas are frequently misdiagnosed or not recognized. The history is typical of a slowly enlarging mass, irregularly contoured, it is fixed to the skin but slides freely over the, underlying tissues, often with a discolouration which varies from red to purple-bluish. Ultrasound examination, MRI-scan and fine-needle aspiration can be helpful if the diagnosis is uncertain. Spontaneous regression has never been observed and malignant degeneration is very rare. Surgical excision with clear margins is the treatment of choice, otherwise recurrence may occur due to incomplete resection.

Facial clefts and associated limb anomalies: description of three cases and a review of the literature.

Facial clefts are rare congenital malformations. In the literature these are sometimes reported in combination with limb malformations, especially ring constrictions. This article describes three children with facial clefts and limb ring constrictions with various expressions. The first case has a lateral cleft with associated limb malformations. This combination has, to our knowledge, not yet been reported. The literature about facial clefting and the amniotic band syndrome and the possible etiology of clefting and constrictions in these cases are discussed.

Role of surgery in mild primary hyperparathyroidism in the elderly.

BACKGROUND: The appropriate management of elderly patients with mild hyperparathyroidism is the subject of much debate. METHODS: A Medline literature search was conducted using the keywords 'hyperparathyroidism', 'asymptomatic' and 'elderly'. The references of the primary sources were examined for further citations. Personally collected cullings from journals and abstracts from journals were used as an additional source of data. RESULTS AND CONCLUSION: No prospective randomized controlled trial comparing parathyroidectomy with conservative management for patients with mild or asymptomatic hyperparathyroidism has been published. There are a number of longitudinal studies that attempt to characterize the natural history of hyperparathyroidism, but most do not stratify patients according to age when assessing outcome. None the less, it is clear that elderly patients present with a different spectrum of problems, particularly indistinct neuropsychiatric and musculoskeletal symptoms, and these are likely to be improved by surgery. The evidence allows the conclusion that the truly asymptomatic elderly patient can be successfully managed conservatively; there is a good prospect of benefit from surgery for those with symptomatic disease, and such patients should not be denied an operative option.

The use of pedicled perforator flaps for reconstruction of lumbosacral defects.

Large lumbosacral defects remain a difficult challenge in reconstructive surgery, especially in the nonparaplegic patient. Traditional options for closure include local rotation or transposition flaps and musculocutaneous flaps. These flaps, however, are not an optimal option in previously irradiated or operated areas, or in cases of large defects. Application of the perforator principle to the traditional musculocutaneous flap creates perforator flaps, which are an additional tool in the treatment of these defects in the nonparaplegic patient. A large amount of healthy, well-vascularized tissue can be transferred on one perforator without sacrificing important underlying muscles. The arc of rotation is also larger than in traditional flaps. The authors present an anatomic overview of three types of pedicled perforator flaps: the superior gluteal artery perforator flap, the lumbar artery perforator flap, and the intercostal artery perforator flap. They also report 4 patients in whom a pedicled perforator flap was used to reconstruct a large lumbosacral defect.

Assessment of a scoring system for breast imaging.

BACKGROUND: Triple assessment is the standard method of assessing symptomatic breast lumps. There is an accepted format for reporting cytology but not for the reporting of mammograms or breast ultrasonographic images. This study describes a scoring system for reporting breast imaging methods. METHODS: Patients with symptomatic breast lumps seen during 1 year were included. All patients underwent triple assessment. Imaging studies were reported using a grading system from 1 to 5. The results of triple assessment were compared with the final histology. RESULTS: Some 127 women had both mammography and ultrasonographic imaging; the final grade was identical in 60 per cent. The positive predictive value of imaging reported as grade 5 or 4 combined with cytology of C5 or C4 was 100 per cent. All lesions with C3 cytology and benign imaging were benign on histological examination whereas if a C3 grade was combined with imaging grade 5 or 4, all the lesions were malignant. CONCLUSION: Combining the imaging grade with the results of aspiration cytology and clinical examination often predicts the final histology in patients with breast disease.

Immediate cytodiagnosis and imaging in the clinical management of discrete benign breast lesions.

Benign breast disease accounts for the majority of referrals to a specialist breast clinic. Delayed investigation prolongs patient anxiety and increases outpatient waiting lists. Few centres offer the triple test of clinical examination, fine needle aspiration cytology (FNAC) and breast imaging by mammography and/or ultrasonography at initial presentation. We have analysed the practicality of such a service during the 12 months following its introduction in our district general hospital. We studied the cohort of 178 patients who presented with a discrete breast lump which was subsequently shown to be benign. A triple test was performed in 72% of all patients. In 100 patients (56%) this was performed at initial assessment. Of these, 87 had clinically benign disease confirmed by FNAC and breast imaging and they were informed of the results within 3 h. A triple assessment during the initial consultation allows the majority of patients with discrete benign breast disease to be given immediate reassurance.
