Abstract
OBJECTIVE There have been few reports addressing methods of dealing with free flap thrombosis after reconstructive surgery for head and neck cancer. The present study, through a detailed analysis of the subsequent course of patients who developed postoperative flap thrombosis, aims to clarify possible methods of salvage surgery in the event of vascular occlusion despite rigorous postoperative follow-up. METHODS We analyzed 59 cases of postoperative thrombosis in 1031 patients who underwent free flap transfer and considered the most appropriate salvage surgery in the event of total flap necrosis. RESULTS The flap salvage rate through vascular reanastomosis was highest for radial forearm flaps, with salvage of jejunal flaps being problematic if postoperative thrombosis occurred. For cases of postoperative thrombosis among patients who underwent reconstruction using a jejunal flap, the period of hospitalization was significantly extended for those patients in whom a second jejunal flap grafting was impossible. For cases of postoperative thrombosis among patients who underwent reconstruction using a radial forearm flap (FA), rectus abdominis flap (RA), or anterior lateral thigh flap (ALT), no significant difference was observed between those undergoing re-grafting with a free flap and those with a pedicled flap. CONCLUSION We concluded that, among patients who undergo reconstruction using a jejunal flap, thrombosis should be discovered at an early stage to enable another jejunal flap re-grafting. For patients who undergo reconstruction using a FA, RA, or ALT, if thrombosis can be discovered at an early stage, there is a possibility of salvaging the flap by means of vascular reanastomosis. If it should prove impossible to salvage the flap, however, primary suture of the defect or reconstruction with a pedicled flap may also be considered.

Abstract
BACKGROUND/AIM Radial forearm free flap, highly regarded in head and neck reconstructive surgery, is known to be one of the most reliable and versatile flaps. The aim of this study was to illustrate the versatility and reliability of a radial forearm flap in reconstruction of a variety of extraoral head and neck defects. METHODS During a period 2001-2007 at the Clinic for Maxillofacial Surgery, Faculty of Dentistry and the Center for Burns, Plastic and Reconstructive Surgery in Belgrade, 19 patients underwent microsurgical reconstructions after extraoral tumor ablation in the head and neck region, using fasciocutaneous radial forearm free flap. RESULTS The overall flap survival rate was 89.5%. The complications that appeared were one partial necrosis and one venous thrombosis that in spite of reanastomosis resulted in a complete flap failure. The donor site healed uneventfully in all patients, except one, who had a partial skin graft failure, that ended in a secondary skin grafting. CONCLUSION For reconstruction in head and neck surgery, with the need for thin, pliable tissues and a long vascular pedicle, radial forearm flap still remains a primary choice. Because of their multiple advantages, free flaps from the radial forearm is a safe method for reconstruction of a variety of extensive extraoral soft tissue defects in the head and neck region.

Abstract
The recent changes in incidence and prevalence of oral squamous cell carcinoma in relation to gender and age mirror the changing patterns of exposure to tobacco and alcohol, the main etiological agents. Most cases of oral cancer are managed by surgery, often combined with radiotherapy. Histopathological assessment of the resection specimen provides information vital for postoperative management and prognosis. This review considers the full range of histological determinants of outcome in relation to the primary oral tumor and any metastatic involvement of the cervical lymphatic system, together with an outline of more general patient factors that may also impact on morbidity and mortality rates.

Abstract
BACKGROUND The acute toxicity of intraoperative radiation therapy (IORT) delivered as an "early boost" after tumor resection in patients with locally advanced head and neck cancer was evaluated. METHODS Twenty-five patients were enrolled in the study. All patients underwent surgery with radical intent, and 17 had microvascular flap reconstruction. The IORT was delivered in the operating room. Twenty patients received adjuvant external beam radiation therapy (EBRT). RESULTS Five patients experienced various degrees of complications in the postoperative period, all of which were treated conservatively. One patient had a partial flap necrosis after EBRT that was treated with flap removal. Six deaths were recorded during the mean follow-up period of 8 months; none of the deaths were related to radiation treatment. CONCLUSION This feasibility study shows that the use of IORT as an early boost is feasible with no increase in acute toxicity directly attributable to radiation.

Abstract
BACKGROUND: Fasciocutaneous tissue transfer is a common reconstructive procedure. Revascularization of flap tissue is an important component of tissue healing. Gene therapy offers an avenue through which the period of pedicle vascular dependency can be reduced. MATERIALS AND METHODS: Rat fasciocutaneous flaps were elevated and a two-hour ischemic time induced. Polycation complex (jet PEI) and human fibrin sealant CROSSEAL® was applied between flap and underlying abdominal tissues. Group 1 (six rats) was the control; Group 2 (seven rats) had vascular endothelial growth factor (VEGF) protein applied; Group 3 (seven rats) had plasmid DNA expressing VEGF applied. Vascular pedicles were ligated on postoperative day 5, percentage flap survival evaluated on day 7. RESULTS: All flaps survived initial ischemia. Mean ± SD percentage area of the flap that survived was 28.1 ± 12.4 (Group 1), 71.6 ± 16.2 (Group 2), and 77.5 ± 12.7 (Group 3) ( P < 0.001, Group 1-3, 2-3). No differences were observed between Groups 2 and 3. CONCLUSIONS: Locally administered VEGF protein or plasmid DNA expressing VEGF enhanced survival of fasciocutaneous flaps.

Abstract
BACKGROUND Free flap reconstruction of head and neck cancer defects is complex with many factors that influence perioperative complications. The aim was to determine if there was an association between perioperative variables and postoperative outcome. METHODS We evaluated 185 patients undergoing free flap reconstruction following ablation of head and neck cancer between 1999 and 2001. Demographic, laboratory, surgical and anesthetic variables were analyzed using univariate and multivariable techniques. RESULTS Ninety-eight patients (53%) developed complications, of which 74 were considered major, giving a major morbidity rate of 40%. Predictors of major complications were increasing patient age, ASA class, and smoking. Predictors of medical complications were ASA class, smoking, age and crystalloid replacement. Predictors of surgical complications were tracheostomy, preoperative hemoglobin, and preoperative radiotherapy. CONCLUSION Patient age, comorbidity, smoking, preoperative hemoglobin, and perioperative fluid management are potential predictors of postoperative complications following free flap reconstruction for cancer of the head and neck.

Abstract
OBJECTIVES Vascular compromise of free flaps most commonly occurs in the immediate postoperative period in association with failure of the microvascular anastomosis. Rarely do flaps fail in the late postoperative period. It is not well understood why free flaps can fail after 7 postoperative days. We undertook a case review series to assess possible causes of late free flap failure. STUDY DESIGN Retrospective review at two tertiary referral centers: Oregon Health Sciences University and University of Alabama at Birmingham. METHODS A review of 1,530 flaps performed in 1,592 patients between 1998 and 2006 were evaluated to identify late flap failure. Late flap failure was defined as failure occurring after postoperative day 7 or on follow-up visits after hospital discharge. A prospective database with the following variables was examined: age, medical comorbidities, postreconstructive complications (fistula or infection), hematoma, seroma, previous surgery, radiation therapy, intraoperative findings at the time of debridement, nutrition, and, possibly, etiologies. RESULTS A total of 13 patients with late graft failure were identified in this study population of 1,530 (less than 1%) flaps; 6 radial forearm fasciocutaneous flaps, 2 rectus abdominis myocutaneous flaps, 4 fibular flaps, and 1 latissimus dorsi myocutaneous flap underwent late failure. The time to necrosis was a median of 21 (range, 7-90) days. Etiology was believed to possibly be pressure on the pedicle in the postoperative period in four patients (no sign of local wound issues at the pedicle), infection (abscess formation) in three patients, and regrowth of residual tumor in six patients. Loss occurring within 1 month was more common in radial forearm flaps and was presented in the context of a normal appearing wound at the anastomotic site, as opposed to loss occurring after 1 month, which happened more commonly in fibula flaps secondary to recurrence. CONCLUSION Although late free flap failure is rare, local factors such as infection and possibly pressure on the pedicle can be contributing factors. Patients presenting with late flap failure should be evaluated for residual tumor growth.

Abstract
BACKGROUND Anesthesiologists and reconstructive surgeons have differing views regarding the control of rotational flap perfusion. Anesthesiologists view the entire body as having flow that is dependent on systemic perfusion pressure, whereas plastic surgeons conjure that systemic administration of vasoactive agents causes vasoconstriction of the pedicle artery and the microvasculature. The aim of this study was to investigate the effects of systemically administered phenylephrine and epinephrine on rotational myocutaneous flap perfusion. METHODS After institutional animal care and use committee approval, seven vertical rectus abdominal myocutaneous (VRAM) flaps were created in six pigs. Under 1.0 minimum alveolar concentration isoflurane anesthesia, pedicle artery blood flow (transit time flow probe) and microvascular perfusion (laser Doppler flow probe) were recorded at baseline and after achieving steady hemodynamics with the systemic intravenous administration of phenylephrine (20, 40, and 80 microg/minute) and epinephrine (0.5, 1, and 2 microg/kg/minute). RESULTS Under stable physiologic conditions, phenylephrine consistently decreased the pedicle artery blood flow and the microvascular perfusion of porcine VRAM rotational flaps, whereas epinephrine consistently increased both flows across the entire dose range studied. Furthermore, epinephrine-induced increases in cardiac output correlated well with the observed increases in pedicle artery blood flow and microvascular perfusion. CONCLUSIONS With the systemic delivery of phenylephrine, rotational myocutaneous flaps react in a manner described by the surgeon. In contrast, the anesthesiologist's model of the hemodynamics is correct for low to moderate doses of epinephrine. Therefore, epinephrine may be the vasoactive agent of choice for treating perioperative hypotension without harming the rotational flap blood flow.

Abstract
Free tissue transfer has revolutionised reconstruction of the head and neck and there are currently few local factors that preclude its use. These include a lack of suitable recipient vessels in the area for microvascular anastomosis. We describe the use of a Corlett loop in which a temporary arteriovenous fistula (AVF) is created with a transposed cephalic vein to enable reconstruction of a mandibular defect with a fibular free flap.

Abstract
BACKGROUND The role of fibula free flaps for reconstruction of through-and-through oromandibular defects is examined. METHODS Thirty-four patients underwent reconstruction of through-and-through oromandibular defects using fibula free flaps that contain large, bilobed skin paddles for simultaneous reconstruction of intraoral mucosa and external skin. We examined the incidence of wound healing complications, the need for revision reconstructive surgery, and factors affecting the incidence of complications. RESULTS Wound healing complications occurred in 50% of patients. There was a relatively high incidence of partial flap necrosis (26%) and revision surgery (41%). The area of the flap skin paddle was significantly associated with the risk of partial flap necrosis and the need for revision surgery. CONCLUSIONS Many through-and-through oromandibular defects can be successfully reconstructed using a fibula free flap that contains a large, bilobed skin paddle. However, wound healing complications are increased when the flap skin paddle area exceeds 300 cm2.

Abstract
INTRODUCTION This retrospective study was intended to determine the incidence and causes of postoperative complications in patients following head and neck reconstruction using microvascular free flaps. PATIENTS AND METHODS A total of 202 consecutive microvascular free flaps were performed for reconstruction of the head and neck by the same surgeon, 85% of the defects arose following the treatment of malignancies. Flap donor sites included latissimus-dorsi flap (n=83), radial forearm (n=35), fibula (n=31), iliac crest (n=36), TRAM flap (n=3), groin flap (n=l), jejunal flap (n=13). The incidence of postoperative complications and patient-related characteristics (age, sex, diagnosis, comorbidity level, operation duration, defect site, history of radiotherapy/chemotherapy) were retrospectively analyzed. RESULTS Free flaps proved to be extremely reliable, with a 2.9% incidence of free flap failure. Postoperative medical complications occurred in 11.4% of cases, with cardiac, pulmonary and infectious complications predominating. CONCLUSION The present study confirms that free flaps are extremely reliable in achieving successful reconstruction of the head and neck. The incidence of postoperative complications is related to the preoperative comorbidity.

Abstract
The aim of this retrospective study is to review the experience of our institution in performing microvascular head and neck reconstruction between 2000 and 2004. During this period, 213 free flaps, including 146 radial forearm free flaps, 60 fibular flaps and 7 scapular flaps, were performed. Free flap success rate and complications were reported. The pre-treatment factors influencing these results were subsequently analyzed. Functional and aesthetic outcomes were evaluated by the same clinician. There were 14 free flap failures, giving an overall free flap success rate of 93.4%. Salvage surgery for recurrent cancer was the only factor correlated with a higher risk of free flap failure (P = 0.0004). The local complication rate was 20.9%. High level of comorbidity (P = 0.009), salvage surgery for recurrent cancer (P = 0.03) and hypopharyngeal surgery (P = 0.002) were associated with a higher risk of local complications. An unrestricted oral diet and an intelligible speech were recovered by respectively 76 and 88% of the patients. Microvascular free flaps represent an essential and reliable technique for head neck reconstruction and allow satisfactory functional results.

Abstract
Some patients who undergo pharyngolaryngoesophagectomy with free jejunal transfer reconstruction have a history of esophagectomy and gastric pull-up. We retrospectively reviewed a series of 12 patients to examine the characteristic problems in free jejunal transfer for patients with a history of esophagectomy and gastric pull-up. There was no postoperative thrombosis. No anastomotic leakage or fistula was found. Five of 12 patients presented postoperatively with dysphagia. Two of the 5 patients showed stricture at the distal anastomosis. Three of the 5 patients showed no stricture. However, their reconstructed tracts were tortuous around the distal anastomosis, which could be a cause of dysphagia. Even in patients with a history of esophagectomy and gastric pull-up, free jejunal transfer can be performed safely, although the functional outcome of swallowing is not always satisfactory.

Abstract
In this study, we examined salvage operations after reexploration in head and neck reconstruction and analyzed ways to solve problems. Free flap reconstruction of the head and neck lesion was carried out for 513 cases in our hospital over the past 12 years. Twenty-one cases of reexploration were caused by postoperative thrombosis (4.1%). We could only salvage seven cases (33.3%) of 21 cases from flap thrombosis. All seven cases were included in the category of venous thrombosis, and they were undertaken within 3 days postoperatively. Our results have shown that once thrombosis occurs, there is little possibility of flap salvage, particularly 3 days after operation and in infectious cases. When no flow phenomena are observed and no flap salvage is deemed possible, aggressive treatment such as a second free flap or next pedicle flap should be chosen as soon as possible to avoid any delay in postoperative treatment.

Abstract
OBJECTIVES The aim of this retrospective study is to evaluate functional results of oromandibular reconstruction with osseous free flaps. MATERIAL AND METHODS A total of 67 patients who underwent oromandibular reconstruction with fibula (n=60) or scapular (n=7) free flap between 2000 and 2004 were included in this study. We analysed functional results (alimentation, elocution, mouth opening and cosmetic appearance) and researched the potentially predictive factors of these results (age, comorbidity, preoperative irradiation, type of defect...; Chi(2) test). RESULTS The rate of free flap success was 89.6%. A functional result considered as normal or subnormal was obtained by more than 50% of patients. Oral alimentation (without tube feeding) and intelligible speech were recovered by 92.5% of patients. Through and through defects and free flap failures were determinant predictive factors of worse functional outcomes. CONCLUSION Fibula free flap is considered as the flap of choice for oromandibular reconstruction and allows excellent functional results.

Abstract
BACKGROUND There is a trend toward linking the reimbursement for health care services to clinical outcome. One such pay-for-performance proposal that affects orthopaedic surgeons is linking reimbursement for hip and knee replacements to measures such as the percentage of patients receiving antibiotics before surgery. We analyzed the risk factors associated with failing to optimally administer preoperative antibiotics before primary hip and knee arthroplasty. METHODS Data on 988 elective primary total hip and knee replacements done at one institution were collected. Multivariate analysis was performed to determine clinical factors associated with administration of antibiotics outside the recommended window (within one hour before the incision). RESULTS Thirteen percent of the patients did not receive optimal antibiotic therapy (within the one-hour window prior to the elective arthroplasty). Five patients (0.5%) received no documented preoperative antibiotics. Patients undergoing total hip arthroplasty were more likely to receive antibiotics outside the one-hour window than were patients undergoing total knee arthroplasty. Longer induction times were associated with administration of antibiotics outside the one-hour window. Certain individual surgeons and anesthesiologists were more likely to administer antibiotics on time. The anesthesiologist effect was more significant than the surgeon effect. CONCLUSIONS Approximately 13% of the patients did not receive optimal antibiotic therapy before total hip and knee replacement. Surgeons can improve their performance score for this measure by focusing antibiotic strategies on patients receiving a hip replacement and on complex cases, by developing systems for antibiotic dosing with the anesthesia team, and by improving documentation.

Abstract
The numbers of free flap donor site as well as their indications are constantly increasing. Despite increasing popularity of microvascular reconstructive procedures, literature lacks clear and objective outcome criteria. This paper reports on a simple outcome classification that has become a routine part of the unit's large workload of microvascular outcome recording. The classification was formed through a retrospective analysis of 241 consecutive cases from 2000 to 2001 and is a five graded numerical classification. Grade 1 equates to total success without co-morbidity and grade 5 to a major complication such as amputation, etc., whatever the status of the flap itself. From 2002 to 2005 the classification was prospectively used on 527 consecutive cases with ease of integration into routine clinical practice. The Classification would enable a more objective record keeping thus analysis of the outcome. It would allow a more realistic comparison of different techniques or donor types as well set a benchmarking level for further improvement of the results.

Abstract
The aim of this study was to retrospectively analyze surgical outcome and complications of 540 free flap procedures performed at the Department of Oral and Maxillofacial Surgery of the University Medical Center Hamburg-Eppendorf during 1987-2005. A total of 532 patients were reconstructed with 540 flaps: 32% were latissimus dorsi flaps, 23% were radial forearm flaps, 21% were iliac crest flaps, 10% were fibula flaps, 6% were jejunal flaps, and 8% were other flaps. Thrombosis of one of the vessels and hematoma were the most frequent causes of failure in microvascular free tissue transfer. A total free flap failure occurred in 34 (6.2%) and a partial flap failure in 42 (7.7%) patients. The most reliable flap in regard to survival was the radial forearm flap. The present study confirms that free flaps are extremely reliable in achieving successful reconstruction of the head and neck.

Abstract
BACKGROUND In university hospitals, free tissue transfer has become a standard method of reconstruction for a broad spectrum of defects. Because of its complexity, free tissue transfer has not been routinely performed in a community hospital setting. This study reports the outcomes of two equal groups of free tissue transfer performed by the same surgeons, comparing the university versus the community hospital setting. METHODS A total of 735 free tissue transfers were performed at one university hospital and six community hospitals in our region over a 10-year study period. Outcome parameters used in this study included wound complications such as infection, dehiscence, delayed healing, hematoma, and fat necrosis. RESULTS A total of 674 operations were performed using 735 free tissue transfers: 386 free tissue transfers were performed at the university hospital (53 percent) and 349 (47 percent) were performed at the community hospital. Categories of free tissue transfer reconstruction included breast, lower extremity, head and neck, and upper extremity reconstructions. Most of the breast reconstructions were performed in the community hospital, whereas most of the lower extremity and head and neck reconstructions were performed at the university hospital. Fifty-one major postoperative complications occurred in the university hospital (14 percent), while 31 (10 percent) occurred in the community hospital. Complication rates did not differ significantly between settings; however, there was a trend toward more wound infections in the university hospital and more cases of fat necrosis in the community hospital, most likely reflected in the differing case mix between hospital settings. CONCLUSION Free tissue transfer is an effective and practical method of reconstruction that has been safely performed in both university and community hospital settings.

Abstract
PURPOSE To prospectively evaluate, in vivo in pigs, an impedance-based multiple-electrode radiofrequency (RF) ablation system for creation of confluent areas of hepatic coagulation. MATERIALS AND METHODS The study was preapproved by the institutional research animal care and use committee. A prototype multiple-electrode RF system that enables switching between three electrically independent electrodes at impedance spikes was created. Forty-two coagulation zones (18 with single, 12 with cluster, and 12 with multiple [three single electrodes spaced 2 cm apart] electrodes) were created at laparotomy in 15 female pigs. Half the ablations were performed for 12 minutes, and half were performed for 16 minutes. The coagulation zones were excised and sliced into approximately 3-mm sections for measurement. Analysis of variance and two-sample t tests (with Bonferroni correction, alpha = .0033) were used to assess for differences between groups. RESULTS At 12 minutes, the mean multiple-electrode coagulation was significantly larger than the mean single-electrode coagulation (minimum diameter, 2.8 vs 1.6 cm; maximum diameter, 4.2 vs 2.0 cm; volume, 22.1 vs 6.7 cm(3); P < .0033 for all comparisons). The mean maximum diameter achieved at 12 minutes with multiple electrodes was significantly larger than that achieved with the cluster electrode (4.2 vs 2.9 cm, P = .02). At 16 minutes, the mean multiple-electrode coagulation (minimum diameter, 3.2 cm; maximum diameter, 4.2 cm; volume, 29.1 cm(3)) was significantly larger than the mean single-electrode (minimum diameter, 1.7 cm; maximum diameter, 2.2 cm; volume, 7.1 cm(3); P < .0033 for all comparisons) and cluster-electrode (minimum diameter: 2.3 cm, P = .007; maximum diameter: 3.2 cm, P = .005; volume: 13.1 cm(3), P = .001) coagulations. CONCLUSION Compared with the single and cluster systems used as controls, the multiple-electrode RF ablation system enabled the creation of significantly larger coagulation zones.

Abstract
In this retrospective study, all free flap transfers used for reconstruction following ablation of head and neck tumors in University Medical Centre Ljubljana between the years 1989 and 1999 were analysed. The data taken from the patients' charts covered the demographic profile, the tumor and free flap details (44 variables for each patient). Logistic regression model was used to identify factors associated with free flap failure and complications. One hundred and sixty-two patients with head and neck tumors underwent microsurgical reconstruction. One hundred and ninety-four free flaps were performed with an overall success rate of 85%. Two significant predictors of free flap complication were identified: diabetes and salvage free flap transfer. Patients with diabetes were five times more likely to develop complications associated with free flaps (p = 0.02). Free flap complications were four times more likely to develop after salvage free flap transfer (p = 0.04). In addition, two significant factors predicting free flap failure were identified: salvage free flap transfer (p = 0.019) and use of interposition vein grafts (p = 0.032). After this study we changed our strategy of free flap selection and preoperative evaluation of the patients with head and neck tumors requiring free tissue transfer. Between January 2000 and January 2005 we performed additional 105 free flaps for head and neck reconstruction after tumor resection in 101 patients and our success rate improved to 94.3%.

Abstract
We present our 14-year experience of free tissue transfer following surgery for head and neck neoplasm. We evaluated 346 patients mean age 57 years, 65% had squamous cell carcinoma; the most frequent sites were oral cavity and mandible (168) craniomaxillo facial region (94) pharynx +/- cervical oesophagus and oropharyngostomes (84). In 327 (95%) cases the reconstruction was a success. Flap revision was necessary in 29 (8.4% of total) and recovery was successful in 10/29. Nine patients (2.6%) died perioperatively. Poor preoperative condition, previous treatment, and requirement for vein graft were significantly associated with increased risk of major complications after surgery. Cosmetic and functional outcomes were assessed on 1-10 scales: 69 and 77% of patients, respectively, had cosmetic and functional results in the 7-10 range, indicating successful outcome. Overall survival probabilities, estimated on 338 patients with malignant disease, were 53% at 2 years and 32% at 5 years. Most patients, but not all, had advanced disease stage, and 188 (54%) had recurrent disease. Hence, overall survival rates are acceptable and justify the use of complex reconstruction procedures in such patients.

Abstract
The purpose of this study was to determine the rate of major and minor flap, donor site, and systemic complications in a consecutive series of 250 free flap operations. The following factors were analyzed to determine their significance on complication rates: age of patient, gender, wound etiology, smoking history, type of flap, operative time, vein graft use, surgeon experience, and the presence of comorbid disease. The major flap, donor-site, and systemic complication rates were 17.2%, 2%, and 6.4%, respectively. The minor flap, donor-site, and systemic complication rates were 7.2%, 12.8%, and 7.2%, respectively. The presence of comorbid medical condition was the only factor which had a statistically significant impact on the rate of major flap complications (P = 0.02). Age and comorbid disease impacted on major systemic complications (P = 0.04).

The jejunum was the donor site in 181 reconstructions (34%), followed by the radial forearm flap in 173 reconstructions (32%); 86% of the reconstructions were immediately after excisions. Surgical re-exploration was necessary in 37 patients (7%); the failure rate from necrosis of the flap was 5%. Factors associated with complications were American Society of Anesthesiology (ASA) class and age.

Abstract
BACKGROUND The aim of this study was to assess blood flow (BF) of microvascular free flaps studied with positron emission tomography (PET) in patients with head and neck squamous cell cancer (HNSCC) undergoing major radical surgery 3-4 weeks after high-dose radiotherapy. METHODS Five patients underwent resection of the HNSCC of the oral cavity followed by microvascular reconstruction with a radial forearm flap. Regional BF in oral and neck tissues was measured with PET using radiolabelled water ([15O]H2O) twice (1-2 and 12-14 days, respectively) following radical surgery. RESULTS In the first postoperative PET study, the median BF in the cutaneous flap area was 5.1 mL/100 g/min, and in the muscle contra-lateral to the recipient site 19.9 mL/100 g/min. A low flap-to-muscle BF ratio appeared to correlate with circulatory incongruity, and thus with poorer flap success. The follow-up study on the second postoperative week supported the results of the primary PET scan. CONCLUSIONS This pilot study suggests that PET using [15O]H2O is a feasible method to quantitatively evaluate BF of the whole free flap in patients operated on for oral

Abstract
BACKGROUND The purpose of this study was to determine whether patients with a poor prognosis for survival were more likely to undergo reconstruction with a pectoralis flap versus a free flap and whether the use of a pectoralis flap offered any perioperative advantage, such as a reduction in medical complications. METHODS Fifty-five consecutive patients who underwent immediate reconstruction after a lateral mandibulectomy were retrospectively reviewed. RESULTS Age >or=70 years (p = .03), moderate or severe comorbidity (p = .02), and involvement of the base of tongue by tumor (p = .04) were significantly associated with decreased utilization of a free flap (n = 36). Comorbidity was the main determinant of medical complications (p = .001) and length of hospital stay (p = .03). CONCLUSIONS Expectations of prognosis bias the surgeon's decision regarding flap selection. Reconstruction with a pectoralis flap does not necessarily contribute toward the desired outcome of reduced medical complications. Any functional comparison between reconstructive groups needs to account for those differences in health status and prognosis that might explain any observed postoperative differences.

Abstract
Background/aim: In the field of contemporary head and neck reconstructive surgery, free vascularized tissue transfer is becoming a gold standard. The aim of this study was to review our clinical results and experience, with use of free microvascular flaps and compare them with the recently published patient series. Methods. During the period from 2001 to 2005, 37 patients underwent microsurgical reconstruction after the tumor ablation in the region of head and neck. Flap viability was monitored intraoperatively with the Ackland test and postoperatively by the clinical observation and mini-Doppler test. Results. The overall success rate was 83.8%. The complications that appeared were: one complete flap necrosis due to venous thrombosis, and five late flap ischemic necroses, in the period from the 10th to 14th postoperative day. Conclusion. Free flap reconstruction of the head and neck is a surgical technique that provides the reconstruction of complex and extensive defects, that could not be performed by using local or regional flaps.

Abstract
OBJETIVO: O estudo pretende relatar a experiência inicial de um serviço de cirurgia plástica ao implantar um grupo de microcirurgia, analisando as complicações e resultados da casuística. MÉTODO: No período de fevereiro de 2003 a junho de 2004, foram realizados 20 procedimentos de microcirurgia reconstrutiva variando em reconstruções de cabeça e pescoço, mama e membros inferiores. As complicações foram divididas em imediatas (intra-operatórias), recentes (até 21dias) e tardias (após 21dias). Foram analisadas complicações relacionadas às reconstruções, divididas em menores (perda parcial do retalho e/ou satisfação parcial do plano pré-operatório) e maiores (perda total do retalho e/ou não satisfação do plano pré-operatório). Em relação às áreas doadoras, foram divididas em menores (com necessidade de re-intervenção cirúrgica) e maiores (deformidade não satisfatória ao cirurgião ou não aceitável ao paciente). Os resultados foram classificados como bons, satisfatórios ou ruins. RESULTADOS: Quinze retalhos sobreviveram (73,68% de sucesso) e em cinco houve perda total. Foram encontradas, em relação à reconstrução, 21,05% de complicações imediatas, 45% de recentes e nenhuma tardia. Em relação à área doadora, foram observadas apenas complicações recentes (35%). Os resultados (reconstrução) foram classificados em bons (55%), satisfatórios (20%) e ruins (25%). Os resultados (áreas doadoras) foram bons (65%), satisfatórios (35%) e ruins (0%). CONCLUSÃO: A incidência aumentada de necrose total do retalho talvez se deva à seleção de pacientes. Observou-se uma grande dificuldade na implantação de um serviço de microcirurgia. Os resultados, bons e satisfatórios em 75% das reconstruções e em 100% das áreas doadoras favoreceram a sedimentação e credibilidade do procedimento.

Abstract
BACKGROUND There are an increasing number of elderly patients requiring free tissue transfer. The risks of complex reconstructions in this patient population remain largely unknown. Therefore, the authors' reason for conducting this study was to review their experience with free tissue transfer in patients aged 70 years or older. METHODS A retrospective review of all free tissue transfers performed over a 10-year period at Memorial Sloan-Kettering Cancer Center was performed and all patients aged 70 years or older were identified. Medical records and the authors' prospectively maintained database were analyzed with respect to comorbidities and postoperative complications. RESULTS Two hundred eleven patients aged 70 years or older (70 to 79 years, n = 184; 80+ years, n = 27) were identified during the study period. Of these, 197 (70 to 79 years, n = 170; 80+ years, n = 27) patients had complete charts for review. Flap survival was 100 percent in the 80+ group and 97 percent in the 70 to 79 group. The overall complication rate was 59.3 percent in the 80+ group and 35.3 percent in the 70 to 79 group (p = 0.030). The medical complication rate was 40.7 percent in octogenarians and 11.8 percent in septuagenarians (p = 0.0004). Overall surgical complications were similar in the two groups. Univariate analysis demonstrated that age was associated with medical complications but not surgical complications. Using multivariate analysis, the authors found that alcohol use and coronary artery disease were independent predictors of overall, medical, and surgical complications. CONCLUSIONS Free tissue transfer may be performed in patients over age 70 with a high degree of technical success. The procedure, however, carries a distinct risk of perioperative mortality and morbidity, particularly in patients over the age of 80. Comorbidities significantly associated with complications include age, alcohol use, coronary disease, and hypertension. This study suggests that prolonged survival may be achieved in some patients; however, a selective approach is required.

Abstract
OBJECTIVE Our objective was to determine which factors are associated with cancer recurrence after microvascular reconstruction of the head and neck for squamous cell carcinoma (SCC). STUDY DESIGN A cohort of patients who fit the inclusion/exclusion criteria were identified retrospectively. METHODS A group of 184 patients who underwent successful surgical resection and simultaneous microvascular reconstruction of the head and neck for treatment of SCC were identified. The mean age was 60 (range 23-90) years, there were 115 males and 69 females, and mean follow-up was 26.2 (range 1-99) months. Various factors were analyzed to determine whether they were associated with cancer recurrence, including those pertaining to 1) recipient vessel choice, 2) prior cancer treatment, and 3) cancer staging criteria. Statistical analysis was performed using SPSS statistical software. RESULTS Overall cancer stage (P = .005), T stage (P = .0001), history of previous cancer treatment (P = .004), and history of previous chemotherapy (P = .044) were found to be statistically significant predictors of cancer recurrence on univariate analysis. However, on multivariate analysis, only T stage (P = .005) and history of previous cancer treatment (P = .008) remained as statistically significant predictors of cancer recurrence. Recipient vessel selection was not statistically associated with cancer recurrence. CONCLUSIONS In our study, only T stage and a history of previous cancer treatment were associated with increased cancer recurrence. Neither the recipient vessel chosen nor its location impacted cancer recurrence. This suggests that recipient vessel selection and preparation for microvascular reconstruction do not jeopardize the adequacy of oncologic resection and are therefore oncologically sound.

Abstract
This study examined free flap reconstruction of surgical defects of the oral cavity and oropharynx after preoperative radiochemotherapy. Included in this analysis are 303 prospectively followed patients who underwent a multimodal treatment regime for advanced oral and oropharyngeal carcinoma. All patients received preoperative radiochemotherapy (Mitomycin C, 5-FU, 50 Gy), ablative surgery, and primary free flap reconstruction. Patient characteristics, surgical parameters like duration of surgery and ischaemia, size of defect, type of transplant, and clinical outcome parameters like duration of intensive care and hospitalization, type of complications, necessity and type of revision surgery were statistically evaluated. Overall flap success rate was 93.1%. Sixty seven patients required revision and 21 flaps (6.9%) were lost. Overall complication rate was 22.1%. Mean duration of intensive care (DOIC) and duration of overall postoperative hospitalization (DOH) were 11.0+/-9.6 days and 35.9+/-26.3 days, respectively. Flap success and flap related complications after 50 Gy focal radiation dosage were found in a comparable range as in published series of reconstructions in uncompromised tissue.

Abstract
PURPOSE OF REVIEW Comorbidity may be an important reason for head and neck surgeons to treat elderly patients less intensively. This article provides an overview of the influence of age and comorbidity on choice of therapy, postoperative complications, and survival. RECENT FINDINGS Several retrospective studies show that elderly patients can undergo surgery if they do not have severe comorbid disorders. Severe comorbidity influences the rate of postoperative complications, and the higher complication rate in older patients reported in some studies is probably due to a higher level of comorbidity. Comorbidity also affects the survival of cancer patients, but several studies have failed to detect a relation between age and survival after correction for comorbidity. Thus, although severe comorbidity may influence the choice of treatment, patient age as such should not be a reason to exclude patients from intensive therapy. SUMMARY If severe comorbidity is not present, elderly patients should receive standard treatment for head and neck cancer. Treatment choice should be based on medical findings and patient preference, not on chronologic age.

Abstract
Pre-existing medical problems have the potential to affect postoperative survival, complications, and health-related quality of life (QoL). Our aim was to explore the relation between past medical history, American Society of Anesthesiologists' (ASA) score, health-related QoL, and survival. We collected data from 278 consecutive patients with previously untreated oral and oropharyngeal squamous cell carcinoma operated on primarily from 1995 to 1999 inclusive. Past medical history was recorded from the case notes, ASA grade from the anaesthetic record, and QoL was measured using the University of Washington Quality of Life Questionnaire (UW-QoL). Responses to questionnaires were received from (71%) at baseline (63%) at 6 months (73%) at 1 year, and (65%) 18 months or longer. Past medical history was associated with lower ASA scores. At baseline both history and ASA scores were related to the UW-QoL. Longitudinally patients in ASA grade 1 or with no past history scored better in these UW-QoL domains. Past history did not predict survival (P = 0.83), nor did the UW-QoL composite score (P = 0.30), whilst ASA was associated with crude survival (P = 0.003) and disease-specific survival (P = 0.03). When analyses were stratified for adjuvant radiotherapy, type of operation, size of tumour, and age then the relation to ASA was maintained and trends in the past history and UW-QoL remained not significant. ASA, which is often recorded as part of preoperative assessment, reflects both survival and health-related QoL, and is more useful than past history alone for predicting outcome.

Abstract
OBJECTIVES Infection is associated with free flap failure in patients undergoing microvascular flap reconstruction. This study investigates the association between infection arising from salivary fistulas, microvascular thrombosis, and free flap failure. STUDY DESIGN Prospective laboratory investigation and retrospective clinical investigation. METHODS The effect of saliva-induced infection on the patency of microvascular thrombosis was studied in an experimental animal model and in a clinical series of patients undergoing free flap reconstruction of the head and neck. In the laboratory phase of this study, rat femoral artery anastomoses were inoculated with freshly collected rat saliva to simulate a postoperative salivary fistula. The incidence of femoral artery thrombosis was determined. In the clinical arm of this study, the incidence of salivary fistulas and resulting clinical outcome in 588 head and neck free flap reconstructions were examined. RESULTS In the animal experiment, arterial patency was 95% after 10 days for both the control group and the salivary contamination group. In the clinical series, 24 patients developed salivary fistulas during the postoperative period. No cases of microvascular thrombosis were attributed to salivary fistula formation. CONCLUSIONS Postoperative salivary fistulas do not appear to be strongly associated as a contributory factor toward free flap failure in head and neck reconstruction. On the basis of our current understanding of this condition, we describe a rational approach for management of patients who develop salivary fistulas after microvascular head and neck reconstruction.

Abstract
BACKGROUND Evaluation of immediate and long-term surgical results in major surgery for the head and neck tumours in elderly patients and identification of tumour and patient related factors that affect the incidence and severity of surgical and medical complications. METHODS Retrospective analysis of a series of 24 consecutive patients aged 70 and over with head and neck tumours undergoing extensive surgical resections with reconstruction with/without osseous and/or soft tissue transfer. Patients' demographics and surgery and tumour related data were extracted from appropriate charts and recorded. Pre-existent comorbid conditions, immediate and long-term surgical and medical complications were analysed. Pre-existing comorbidities were graded and staged using the Comorbidity Data Collection Form. Postoperative surgical and medical complications were scored according to their severity. RESULTS Overall complication rate in present study was 63% and 54% of patients experienced clinically important surgical and/or medical complications. However, medium admission time remained at 16 days. Presence of advanced comorbidity, longer operative times and advanced stage of disease seemed to influence the development of surgical or medical complications. CONCLUSIONS Major surgery for head and neck tumours is of great value even in elderly patients providing very good surgical results with acceptable complication rates. The choice of treatment modality should be based on all factors affecting the treatment outcomes. In particular, the presence of the co-existent underlying diseases should be assessed meticulously and in cases with clinically important comorbidities the surgical treatment stress should be reduced to minimum.

Abstract
A study was conducted to assess the effect of intraoperatively administered inotropic agents on blood flow in the recipient and donor vessels, during breast reconstruction with a muscle sparing free TRAM flap. Twenty-one consecutive patients were randomized into 3 groups receiving either dopamine, dobutamine, or placebo. When the flap and all vessels had been fully dissected but not yet divided, the study drug was administered intravenously for 15 minutes. Hemodynamic parameters and transit-time flow of the thoracodorsal and inferior epigastric arteries were monitored. Both dobutamine and dopamine infusions resulted in significant raises in cardiac output and mean arterial pressure. However, while dobutamine resulted in a higher cardiac output (P = 0.001) and a decrease in systemic vascular resistance (P = 0.028), the increase in mean arterial pressure was greater with dopamine (P = 0.002). Only the dobutamine group showed increased blood flow, in both the thoracodorsal (P = 0.043) and the inferior epigastric (P = 0.043) arteries. If vasoactive agents are needed during microvascular anesthesia, dobutamine seems to be more advantageous than dopamine.
