Should advanced age be a contraindication to the surgical management of head and neck cancer patients? A retrospective chart review was performed of patients aged ≥80 years treated surgically for a head and neck malignancy during the period 1996–2011 in a tertiary care cancer centre. The average follow-up was 32 months. Fifty-three patients were identified (mean age 85 years). Cardiovascular disease was the most prevalent co-morbidity (43%). Forty-five patients (85%) had oral cavity/oropharynx squamous cell carcinoma. Surgeries performed included 40 neck dissections and 12 microvascular free flaps. The average length of hospital stay (LOS) was 6.4 days. An increased LOS was significant in patients requiring free flap reconstruction (P < 0.01). There were no perioperative deaths or free flap failures. The most common postoperative complications were cardiovascular (n = 8), infection (n = 10), and delirium (n = 6). Thirty-four patients were discharged directly home. Free flap reconstruction did not adversely affect discharge disposition (P > 0.05). More than 75% of patients did not report any major limitations to their activities of daily living. Major head and neck surgical procedures can be tolerated by patients of advanced age using careful patient selection. Age alone should not be a primary factor in the management of head and neck cancer patients.  相似文献

The selection of the superficial or deep drainage system for use with the radial forearm free flap (RFFF) remains controversial. The aim of this study was to identify the optimal drainage system for single venous anastomosis. A systematic review and cumulative meta-analysis was performed to assess superficial and deep system single venous anastomosis for use with the RFFF in postoperative reconstruction of the head and neck. This study included 1073 flaps (495 superficial system-based flaps, 578 deep system-based flaps) reported in six studies. The outcomes assessed in the studies selected for this meta-analysis included venous compromise, flap failure, and the salvage success rate. Venous compromise was more common in the superficial system group (odds ratio (OR) 2.29, 95% confidence interval (CI) 1.36–3.86, P = 0.002). The rate of successful salvage was higher with the superficial system (OR 8.19, 95% CI 1.75–38.3, P = 0.008). The rate of flap failure was lower in the superficial system group (OR 0.30, 95% CI 0.04–2.48, P = 0.27). Although the deep system showed a lower risk of venous compromise, the evidence provided by the meta-analysis was insufficient to determine which type of drainage system is more suitable for single venous anastomosis in RFFF. All included studies were cohort studies; therefore, findings must be interpreted with caution.  相似文献

This retrospective study was performed to review 1038 patients who underwent mandibular reconstruction with free vascularized bone flaps at a single institution between 2006 and 2017. Of these patients, 827 (79.67%) had fibula flaps, 197 (18.98%) had deep circumflex iliac artery perforator (DCIA) flaps, and 11 (1.06%) had scapula bone flaps. The most common pathological diagnosis was ameloblastoma (n = 366, 35.26%), followed by squamous cell carcinoma (n = 278, 26.78%) and osteoradionecrosis (n = 152, 14.64%). Fifty-seven patients (5.49%) had major complications requiring surgical intervention and one patient died of a pulmonary embolism. Venous crisis was the most frequent major complication (n = 20, 1.93%), followed by haematoma (n = 17, 1.64%) and flap necrosis (n = 14, 1.35%). One-stage mandibular reconstruction was preferred whenever possible, as this generally decreases the financial and hospitalization burden. The four-segment method of jaw reconstruction appeared to achieve good aesthetic appearance results in Asian patients and this was not associated with a higher risk of segment ischemia compared with the three-segment method.  相似文献

The aims of this study were: (1) to compare the visual analogue scale (VAS) with the point evaluation system (PES) in the subjective evaluation of donor-site morbidity after fibula free flap transfer; (2) to compare the functional outcomes of fibula free flap surgery between patients with a normal body mass index (BMI) and patients with a high BMI, and between skin paddle and non-skin paddle harvesting; and (3) to determine the correlation between functional outcomes and related factors. This study included 15 patients who underwent a vascularized fibula free flap transfer for oral and maxillofacial reconstruction. Demographic data, preoperative, intraoperative, and postoperative data were collected. Subjective self-evaluation of functional outcomes was done using a VAS followed by a PES. Comparison of the VAS and PES scores was assessed with Pearson's correlation coefficient. The statistical significance was set at P < 0.05. The VAS score was significantly correlated with the PES score (r = 0.63, P = 0.01). The tourniquet times for the skin paddle group were longer than for the non-skin paddle group (P = 0.02), while the satisfaction score of the non-skin paddle group was higher than that of the skin paddle group (P = 0.03). The VAS is a potential option for the subjective evaluation of donor-site morbidity after fibula free flap transfer.  相似文献

Reconstruction with a free flap is routine in head and neck surgery. However, reliable assessment of perfusion can be difficult, so we prospectively evaluated it in 4 types of microvascular free flaps in the oral cavity (n = 196) and assessed differences in blood flow by non-invasive monitoring with a laser Doppler flowmetry unit. We measured oxygen saturation, haemoglobin concentration, and velocity on the surface of the flap preoperatively at the donor site, and on the flap on the first, second, and seventh postoperative days, and after 4 weeks in 186/196 patients, mean (SD) age of 60 (13) years. We studied the radial forearm (n = 76, 41%), fibular (n = 45, 24%), anterolateral thigh (n = 53, 28%), and soleus perforator (n = 12, 7%) flaps. The values for the radial forearm flap differed significantly from the others. There were significant differences in haemoglobin concentrations between the fibular and soleus perforator flaps, and between the anterolateral thigh and soleus perforator flaps (p = 0.002 each). Free flaps are unique in the way that perfusion develops after microvascular anastomoses. Knowledge of how each flap is perfused may indicate different patterns of healing that could potentially influence long term rehabilitation and detection of future deficits in perfusion.  相似文献

The objective was to describe the utility of the chimeric posterior tibial artery flap (CPTAF) in the restoration of compound defects in the oral and maxillofacial region. Patients who underwent head and neck reconstruction using a CPTAF between February 2018 and February 2019 were included. Special consideration was given to the distribution of septocutaneous perforators (SPs), indications, flap survival, and complications. Nine patients were included. All flaps survived. One patient developed a surgical site infection, which was managed conservatively. The CPTAF was raised as a bipaddle skin flap without muscle (n = 1), with the gastrocnemius muscle (n = 6), or with the soleus muscle (n = 2). The number of SPs ranged from three to five (mean 4 ± 0.8). The SPs were mostly located between 4 cm and 20 cm proximal to the medial malleolus (mean 9.5 ± 3.8 cm). The skin paddle was used to reconstruct skin or mucosal defects, whereas the muscle part was used to fill the dead space (n = 7) or to support the orbital contents (n = 1). The donor site healed with no associated functional complications. The CPTAF is a good option for the restoration of composite tissue defects in the head and neck region. It offers flexibility during flap inset and provides the appropriate bulk to repair defects in multiple planes.  相似文献

The aim of this study was to evaluate the role of computed tomography angiography (CTA) in the diagnosis of vascular stenosis at the vascular pedicle of head and neck microvascular free flaps. A prospective study was done of 65 consecutive patients (49 male, 16 female; mean age 55 years) who had undergone head and neck microvascular free flap reconstruction. All patients underwent 64-slice CTA of the carotid artery. Post-processing with volume rendering reconstruction of CTA images was done. There was excellent inter-observer agreement (weighted kappa = 0.82, 95% confidence interval (CI) 0.74–0.93) in grading of the degree of vascular stenosis. The true sensitivity of CTA for diagnosis of stenosis of the vascular pedicle to the flap was 63% (95% CI 63–100%). Patients with failed flaps showed complete occlusion (n = 2) on CTA and underwent a replacement flap procedure. Patients with failing flaps showed severe stenosis (n = 6) of the vascular pedicle on CTA and underwent revision surgery. There was no change in the degree of stenosis on follow-up CTA for patients with moderate stenosis (n = 9). CTA is a reliable, non-invasive, high-quality imaging tool for the diagnosis and grading of vascular stenosis of the vascular pedicle of head and neck microvascular free flaps.  相似文献

The aim of this study was to determine the prevalence of burnout syndrome among Brazilian oral and maxillofacial surgeons and its relationship with socio-demographic, clinical, and habit variables. The sample of this study comprised 116 surgeons. The syndrome was quantified using the Maslach Burnout Inventory (General Survey), which defines burnout as the triad of high emotional exhaustion, high depersonalization, and low personal accomplishment. The criteria of Grunfeld et al. were used to evaluate the presence of the syndrome (17.2%). No significant differences between the surgeons diagnosed with and without the syndrome were observed according to age (P = 0.804), sex (P = 0.197), marital status (P = 0.238), number of children (P = 0.336), years of professional experience (P = 0.102), patients attended per day (P = 0.735), hours worked per week (P = 0.350), use of alcohol (P = 0.148), sports practice (P = 0.243), hobbies (P = 0.161), or vacation period per year (P = 0.215). Significant differences occurred in the variables sex in the emotional exhaustion subscale (P = 0.002) and use or not of alcohol in the personal accomplishment subscale (P = 0.035). Burnout syndrome among Brazilian surgeons is average, showing a low personal accomplishment.  相似文献

The purpose of this study was to evaluate the outcomes of second salvage surgery with extended vertical lower trapezius island myocutaneous flap (TIMF) reconstruction for patients with re-recurrent oral cavity and oropharyngeal squamous cell carcinoma (SCC). The subjects were 23 patients with advanced re-recurrent oral and oropharyngeal SCC undergoing second salvage surgery and reconstruction with a TIMF. A TIMF with a skin paddle measuring 6 cm × 7 cm to 10 cm × 22 cm was used to reconstruct the major defects. Three patients experienced minor complications: minor flap failure (n = 1), wound dehiscence at the donor site (n = 1), and an orocutaneous fistula (n = 1). The patients were followed for 3–72 months. Fifteen patients were alive with no evidence of disease, two were alive with disease, and six died of local recurrence or distant metastases. Second salvage surgery remains an effective treatment modality for select patients with advanced re-recurrent oral and oropharyngeal SCCs, and the extended vertical lower TIMF is a large, simple, and reliable flap for reconstructing the major defect following second salvage surgery.  相似文献

The aim of this study was to assess the effectiveness of early exploration of anterolateral thigh (ALT) free flap compromise in head and neck reconstruction and to correlate this with the salvage success rate. The perioperative data of 1051 patients with 1072 ALT flap reconstructions were reviewed retrospectively for the period January 2002 to December 2012. Outcome measures included ethnicity, defect type, incidence and timing of flap compromise, type of flap compromise, causes of vascular occlusion, and salvage rate. The success rate of free flap reconstruction was 97.3% (1043/1072). Of the 29 failures, 21 were complete and eight were partial failures (10–40% of the flap). Venous occlusions occurred in 39 flaps (83.0%) and arterial occlusions in five flaps (17.0%). Six cases were detected within 8 h postoperatively, 13 at 8–16 h postoperatively, seven at 16–24 h postoperatively, and 18 at 24–48 h postoperatively, with respective salvage rates of 66.7%, 61.5%, 28.6%, and 22.2%; three cases detected after 48 h failed. The salvage rate at ≤16 h (62.2%) was much higher than that at >16 h (21.4%, P = 0.0039). Early detection, re-exploration, and effective handling of the flap crisis increases the rate of flap salvage tremendously.  相似文献

This review was performed to validate the clinical efficacy of acellular dermal matrix (ADM) for plastic periodontal and implant surgery. Four electronic databases and a manual search were utilized to select randomized clinical trials (RCTs) published until March 2019. Overall, 28 RCTs were included: 25 on teeth and three on implants. For plastic periodontal surgery, ADM exhibited a comparable gingival recession reduction (RecRed) and soft tissue thickness (STT) gain to connective tissue graft (CTG). Subgroup analyses revealed that ADM obtained a similar keratinized tissue width (KTW) gain to CTG within 3–6 months postoperative, but significantly less KTW gain at 1–5 years postoperative (P = 0.01, mean difference (MD) −0.86 mm). Analyses comparing ADM with free gingival graft (FGG) demonstrated similar RecRed but significantly more KTW/STT gain favouring FGG (KTW: P = 0.01, MD −1.78 mm; STT: P = 0.01, MD −0.77 mm). Significantly more RecRed and KTW/STT gain were verified in ADM + coronally advanced flap/laterally positioned flap compared with these flaps alone (RecRed: P < 0.00001, MD 0.65 mm; KTW: P = 0.001, MD 0.66 mm; STT: P < 0.00001, MD 0.59 mm). Limited data for implant surgery indicated a similar trend as for periodontal surgery. Concerning patient-reported outcomes, ADM achieved favourable aesthetic appearance, alleviation of dentinal hypersensitivity, and less surgical morbidity. In conclusion, ADM exerted comparable clinical efficacy to autogenous tissue for root coverage procedures, with good long-term stability. However, for soft tissue augmentation, ADM exhibited inferior 3–6-month postoperative outcomes compared with FGG and less long-term stability of KTW gain compared with CTG.  相似文献

The objective was to evaluate the available published data on sinonasal melanoma and analyse its clinical features, treatment modalities, and prognostic factors. An electronic search was undertaken in March 2018 in multiple databases. Eligibility criteria included publications with sufficient clinical, histological, and immunohistochemical information to confirm the diagnosis. Seventy-three publications (439 cases) were included. The lesion was more prevalent in females than in males. There was a higher prevalence in the seventh and eighth decades of life. The lesions mainly presented as epistaxis and commonly involved the nasal cavity. Age (>67.6 years; P = 0.0012), primary location (middle turbinate; P = 0.0112), disease stage (advanced disease stage; P = 0.0026), treatment (radiotherapy; P = 0.0111), recurrence (recurrence presented; P = 0.0137), and distant metastasis (distant metastasis presented; P = 0.0011) were independently associated with a lower survival rate. Recurrence was significantly correlated with age (>67.6 years; P = 0.0021), sex (males tended to present a higher recurrence rate than females; P = 0.0051), disease stage (stages III and IV presented a higher recurrence rate than stages I and II; P = 0.0331), and histological type (amelanotic lesions presented a higher index of recurrence than melanotic lesions; P = 0.0095). In conclusion, sinonasal melanoma is a neoplasm with a poor prognosis, presenting a 30.69% possibility of survival after 5 years.  相似文献

Throat packs are commonly used in maxillofacial surgeries. However, the evidence to support the benefits of their use is controversial. The aim of this study was to evaluate the effectiveness of throat packs in preventing postoperative nausea and vomiting, and their influence on the incidence of sore throat and dysphagia in patients undergoing orthognathic surgery. This was a prospective double-blind randomized study with 54 patients, who were randomized to two groups: with throat pack (n = 27) and without throat pack (n = 27). Fifty patients (25 in each group) were included in the analysis; 66% female and 34% male, mean age 29.44 ± 8.53 years. Postoperative nausea and vomiting (Kortilla scale), sore throat (visual analogue scale), and dysphagia were evaluated. Statistically significant differences in favour of the without-pack group were found for the variables throat pain at 24 hours (P = 0.002) and dysphagia at 2 hours (P = 0.007) and 24 hours (P < 0.001). There was no difference between the groups regarding postoperative nausea and vomiting (P = 1.00). The results of this study indicate that throat packs as utilized here do not prevent postoperative nausea and vomiting and are associated with worse sore throats and postoperative dysphagia.  相似文献

The predictive value of the Ki-67 labelling index and its relationship with radiosensitivity in oral squamous cell carcinoma (SCC) remains controversial. We sought to evaluate whether the expression of Ki-67 antigen found in SCC of the tongue and the floor of the mouth is an indication for postoperative radiotherapy (PORT). The first study group included 34 patients who were treated only with primary surgery, while the second group included 26 patients who underwent primary surgery combined with PORT. The correlation between Ki-67 expression and loco-regional recurrence, as well as the 5-year disease-specific survival, was assessed in the two groups. Cases of high-proliferative tumours showed a significantly higher risk of loco-regional recurrence (P = 0.018) and a poorer prognosis (P = 0.001) only in the 34 patients treated with surgery alone. In multivariate Cox regression analysis, high Ki-67 expression was an independent predictor of loco-regional recurrence (HR 5.42, P = 0.029) and disease-specific survival (HR 9.02, P = 0.004). The correlation between Ki-67 expression and the risk of loco-regional recurrence in SCC of the tongue and the floor of the mouth may be useful in the selection of patients at a higher risk of recurrence who would benefit from PORT, despite adequate margins of resection and early stage of the disease.  相似文献

Four free-flap types were compared regarding perioperative blood perfusion parameters and to define critical values for success. 166 cases were investigated: radial forearm flap (fasciocutaneous, n = 89); fibula flap (osteocutaneous, n = 32); ALT flap (myocutaneous, n = 25); soleus perforator flap (n = 20). All flaps were monitored with simultaneous laser-Doppler flowmetry and tissue spectrophotometry intra- and postoperatively up to 14 days. In 24 (15%) of 166 cases perfusion irregularity occurred. Operative exploration was performed in 12 cases (9 successful). 11 flaps (5 radial forearm, 3 fibula, 2 ALT, 1 perforator) were lost due to vascular compromise, which led to an overall success rate of 93%. Rapid increase in haemoglobin concentration of > 30% identified venous congestion. Abrupt decline of blood flow and haemoglobin oxygenation indicated arterial occlusion. For radial forearm flaps haemoglobin oxygenation of 15% and a deep flow of 20 AU were identified as minimum values for flap viability. For fibula, ALT, and perforator flaps haemoglobin oxygenation of 10% and a deep flow of 15 AU were determined as the minimum values. This non-invasive technique was an accurate method for evaluating viability of free-flaps.  相似文献

Better cancer treatment has led to a steadily growing population of cancer survivors suffering from late adverse effects after cancer treatment. The aim of this study was to investigate whether there has been an increase in free flap reconstruction due to osteoradionecrosis (ORN). A retrospective review was conducted to identify all consecutive head and neck free flap reconstructions performed over an 18-year period (1995–2012) at Karolinska University Hospital. A total of 235 free flaps were identified. Cases were divided into two groups: head and neck cancer reconstructions and ORN reconstructions. A comparison between the two groups showed longer survival (P < 0.001) and higher rates of late complications (P < 0.001) among ORN cases. ORN as an indication for reconstruction increased over time, from 7.0% of the total number of free flaps performed in 1995–2000, to 15.2% during the period 2001–2006, and to 27.3% in 2007–2012 (P < 0.001). This, in accordance with the results of other studies, highlights the importance of the appropriate allocation of resources within the healthcare system to treat this patient group within the steadily increasing population of cancer survivors.  相似文献

Bleeding is a feared complication of minor oral surgery in patients on treatment with antiplatelet agents and there is no agreed strategy regarding the cessation or not of antiplatelet treatment. The aim of this systematic review was to evaluate bleeding with minor oral surgery in patients on dual antiplatelet therapy (DAPT), single antiplatelet therapy (SAPT), or no antiplatelet therapy (no APT). The PubMed, Embase, Web of Science, and Cochrane Library databases were screened. Sixteen studies were included. DAPT was continued in all studies. The perioperative bleeding risk was significantly higher for DAPT than for SAPT (risk ratio (RR) 10.16, P =  0.010; risk difference (RD) 0.35, P =  0.269), but not higher compared to no APT (RR 6.50, P =  0.057; RD 0.19, P =  0.060). The postoperative bleeding risk was significantly elevated for DAPT compared to SAPT (RR 2.61, P =  0.010) and no APT (RR 3.63, P =  0.035), but only by 1% (RD 0.01, P =  0.103) and 1% (RD 0.01, P =  0.421), respectively. Clinically, this may be considered quite similar. Additionally, local haemostatic measures could control all reported bleeding and no lethal events occurred. Therefore, DAPT interruption is not advised before minor oral surgery.  相似文献

Diabetes mellitus is generally considered a risk factor for impaired wound healing. This study aimed to evaluate the glycaemic status of patients undergoing neck dissection and describe its impact on postoperative outcomes, especially wound healing. A retrospective analysis was performed of the preoperative, intraoperative, and postoperative glycaemic data obtained from the medical charts of 60 adult patients who had undergone 64 neck dissections. Nine of the 64 procedures were performed in diabetic patients (14.1%). The average glucose values were: preoperative 5.99 ± 1.25 mmol/l, intraoperative 8.90 ± 2.62 mmol/l, and postoperative 10.01 ± 2.49 mmol/l. All registered preoperative hyperglycaemia cases (eight cases) were diabetic. Postoperative insulin therapy was done in 14 procedures (21.9%). Wound healing complications were found in five patients (7.8%); there was no wound infection. There was no association of wound healing complications with preoperative diabetic status (P = 1.000), preoperative glucose control (P = 1.000), preoperative (P = 0.469), intraoperative (P = 0.248), and postoperative (P = 0.158) glucose values, or with postoperative glucose control (P = 0.577). These data do not support the association of stress-induced hyperglycaemia or diabetes mellitus with postoperative wound healing problems in neck dissection.  相似文献

The purpose of this study was to outline lower leg vessel anatomy and to investigate reliability and limitations of magnetic resonance angiography (MRA) in patients proposed for microvascular fibula transplantation (free fibula flap (FFF)).We retrospectively investigated MRAs of 99 patients considered for FFF. Frontal MRA planes and maximal intensity projections (MIPs) were evaluated for fibula lengths, anatomical branching pattern, arterial stenoses and fibular perforator positions in both legs (n = 198).Normal branching patterns were observed in 168 (85.3%) legs. Twenty-nine (14.7%) legs presented abnormal branching patterns. Once (0.5%) the anterior, 19 times (9.6%) the posterior tibial artery were absent or hypoplastic. Nine (4.6%) lower legs presented an arteria peronea magna. Average length of the tibiofibular trunk (TFT) was 3.3 ± 0.15 cm. A total of 492 perforators were found with an average of 2.5 (± 0.82 ± 0.99) perforators per leg. A mapping of perforator run-offs was illustrated true to scale. Lower limb stenoses were distributed in the anterior tibial artery (14.1%), in the posterior tibial artery (11.1%) and in the fibular artery (8.1%). Smoking (P = 0.828), diabetes (P = 0.727) and peripheral arterial occlusive disease (P = 0.172) did not correlate with presence of stenoses.Preoperative lower limb angiography avoids postoperative complications. MRA reliably and non-invasively identifies anatomical variants and arterial stenoses without radiation. Illustration of perforator run-offs enhances incision planning for fibula harvest.  相似文献

Surgical practice during the coronavirus disease 2019 (COVID-19) pandemic has changed significantly, without supporting data. With increasing experience, a dichotomy of practice is emerging, challenging existing consensus guidelines. One such practice is elective tracheostomy. Here, we share our initial experience of head and neck cancer surgery in a COVID-19 tertiary care centre, emphasizing the evolved protocol of perioperative care when compared to pre-COVID-19 times. This was a prospective study of 21 patients with head and neck cancers undergoing surgery during the COVID-19 pandemic, compared to 193 historical controls. Changes in anaesthesia, surgery, and operating room practices were evaluated. A strict protocol was followed. One patient tested positive for COVID-19 preoperatively. There was a significant increase in pre-induction tracheostomies (28.6% vs 6.7%, P = 0.005), median hospital stay (10 vs 7 days, P = 0.001), and postponements of surgery (57.1% vs 27.5%, P = 0.01), along with a significant decrease in flap reconstructions (33.3% vs 59.6%, P = 0.03). There was no mortality and no difference in postoperative morbidity. No healthcare personnel became symptomatic for COVID-19 during this period. Tracheostomy is safe during the COVID-19 pandemic and rates have increased. Despite increased rescheduling of surgeries and longer hospital stays, definitive cancer care surgery has not been deferred and maximum patient and healthcare worker safety has been ensured.  相似文献
