The objective of this study was to evaluate the safety and thus the efficacy of microvascular free tissue transfer in the elderly patient population. Free flaps for different types of reconstructions were analyzed to verify whether free tissue transfer is feasible in the elderly. Between 1993 and 2003, 102 free flaps were performed in 94 patients who were aged 70 years or older. There were 75 male and 19 female patients, with a mean age of 73.8 years (range, 70 to 87 years). Different types of free flaps were performed for head and neck (n = 78), lower extremity (n = 12), and trunk and upper extremity (n = 4) reconstruction. Nine flaps underwent reexploration and four of them were lost, for an overall success rate of 96 percent. Medical complications in the postoperative period were further evaluated. A total of 32 medical complications were seen in 29 patients. Only one patient died because of postoperative complications. The frequency of medical complications was further analyzed in detail. Effects of American Society of Anesthesiologists status, operation time, and age on complication rate were evaluated statistically. Only American Society of Anesthesiologists status was statistically significant for the occurrence of postoperative medical complications; class III and IV patients were at higher risk than class I and II. Neither operation time nor age was predictive of postoperative complications. Microvascular free tissue transfer is a safe and reliable option in the elderly population. The success rate of free flaps is not different from that for other age groups. The rate of postoperative medical complications was 31 percent (29 of 94 patients); most complications were in American Society of Anesthesiologists class III and IV patients.

We review the pathogenesis of atherosclerosis and the issues that must be taken into consideration when performing microsurgery in atherosclerotic patients. Atherosclerosis is a systemic disease, and may affect the success of microsurgery. Atherosclerotic patients have a tendency toward thrombosis, because the nature of the arteries is changed. Such patients are usually old and have additional medical problems. To increase the success rate of microsurgery in atherosclerotic patients, special precautions should be considered. Patients must be evaluated properly for the suitability of microsurgery. The microsurgical technique requires a meticulous approach, and various technical tricks can be used to avoid thrombosis. Recipient-vessel selection, anastomotic technique, and the use of vein grafts are all important issues. Prophylactic anticoagulation is recommended in severely atherosclerotic patients. Close monitoring of the patient and flap is necessary after the operation, as with routine microvascular free-tissue transfers. We conclude that atherosclerosis is not a contraindication for microsurgery. If the microsurgeon knows how to deal with the difficulties in atherosclerotic patients, microsurgery can be performed safely.

Based on angiosome principles and application of perforator principles to the surgical reduction of lymphedema, effective, long-lasting, and cosmetically appealing results are achieved in a single-stage procedure.

To improve aesthetic and functional outcomes in the reconstruction of severe anterior neck burn deformities and to reduce donor-site morbidity, pre-expansion of free-flap donor sites was performed in eight patients. In the first stage of reconstruction, the tissue expander was placed and gradually inflated over a period of 6 weeks. In the second stage, the anterior neck scar was resected up to the limits of the aesthetic unit of the neck, radical release of neck contracture was achieved by transection of contracted platysma muscle, and immediate coverage with a pre-expanded groin or scapular free flap was performed. The early postoperative course was uneventful. Physical therapy was started 1 week after the reconstruction. Long-term follow-up (mean, 4 years) of patients who underwent reconstruction of extensive neck burn deformities demonstrated good aesthetic and functional results. The advantages and drawbacks of using pre-expanded free flaps in the treatment of neck burn contractures are discussed.

A new device (a tackshooter) to apply bioabsorbable tacks in craniofacial surgery has been developed. This new device was used in 15 children who underwent various cranioplasty procedures to demonstrate its reliability and simple technical application in cranial bone osteofixation. Bone segments were fixed together and to the cranial bones using Biosorb plates and tacks. Stable and secure fixation was obtained intraoperatively, with reduced operative time (10-15%) compared with earlier use of plates and screws. However, its use in very thin bone (<1 mm thick) is very limited because of bone fragility. In conclusion, use of tacks and a tackshooter reduces operative time, risk of infection and blood loss, and consequently costs. It is therefore very useful in selected craniofacial cases.

This result cautions surgeons about the possibility of vascular pedicle asymmetry between two feet in bilateral toe harvest. It proves once more the advantage of a retrograde pedicle dissection technique, which allows for a safe and straightforward toe harvest regardless of the vascular pedicle course variations.
