Project description:ImportanceProlonged anesthesia and operative times have deleterious effects on surgical outcomes in a variety of procedures. However, data regarding the influence of anesthesia duration on microvascular reconstruction of the head and neck are lacking.ObjectiveTo examine the association of anesthesia duration with complications after microvascular reconstruction of the head and neck.Design, setting, and participantsThe American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database was used to collect data. In total, 630 patients who underwent head and neck microvascular reconstruction were recorded in the NSQIP registry from January 1, 2005, through December 31, 2013. Patients who underwent microvascular reconstructive surgery performed by otolaryngologists or plastic surgeons were included in this study. Data analysis was performed from October 15, 2015, to January 15, 2016.ExposuresMicrovascular reconstructive surgery of the head and neck.Main outcomes and measuresPatients were stratified into 5 quintiles based on mean anesthesia duration and analyzed for patient characteristics and operative variables (mean [SD] anesthesia time: group 1, 358.1 [175.6] minutes; group 2, 563.2 [27.3] minutes; group 3, 648.9 [24.0] minutes; group 4, 736.5 [26.3] minutes; and group 5, 922.1 [128.1] minutes). Main outcomes include rates of postoperative medical and surgical complications and mortality.ResultsA total of 630 patients undergoing head and neck free flap surgery had available data on anesthesia duration and were included (mean [SD] age, 61.6 [13.8] years; 436 [69.3%] male). Bivariate analysis revealed that increasing anesthesia duration was associated with increased 30-day complications overall (55 [43.7%] in group 1 vs 80 [63.5%] in group 5, P = .006), increased 30-day postoperative surgical complications overall (45 [35.7%] in group 1 vs 78 [61.9%] in group 5, P < .001), increased rates of postoperative transfusion (32 [25.4%] in group 1 vs 70 [55.6%] in group 5, P < .001), and increased rates of wound disruption (0 in group 1 vs 10 [7.9%] in group 5, P = .02). No specific medical complications and no overall medical complication rate (24 [19.0%] in group 1 vs 22 [17.5%] in group 5, P = .80) or mortality (1 [0.8%] in group 1 vs 1 [0.8%] in group 5, P = .75) were associated with increased anesthesia duration. On multivariate analysis accounting for demographics and significant preoperative factors including free flap type, overall complications (group 5: odds ratio [OR], 1.98; 95% CI, 1.10-3.58; P = .02), surgical complications (group 5: OR, 2.46; 95% CI, 1.35-4.46; P = .003), and postoperative transfusion (group 5: OR, 2.31; 95% CI, 1.27-4.20; P = .006) remained significantly associated with increased anesthesia duration; the association of wound disruption and increased anasthesia duration was nonsignificant (group 5: OR, 2.0; 95% CI, 0.75-5.31; P = .16).Conclusions and relevanceIncreasing anesthesia duration was associated with significantly increased rates of surgical complications, especially the requirement for postoperative transfusion. Rates of medical complications were not significantly altered, and overall mortality remained unaffected. Avoidance of excessive blood loss and prolonged anesthesia time should be the goal when performing head and neck free flap surgery.Level of evidence3.

Project description:Free tissue transfer has revolutionized the management of complex head and neck defects. Perforator flaps represent the most recent advance in the development of free flap surgery. These flaps are based on perforating vessels and can be harvested without significant damage to associated muscles, thereby reducing the postoperative morbidity associated with muscle-based flaps. Elevation of perforator flaps requires meticulous technique and can be more challenging than raising muscle-based flaps. Use of a Doppler device enables reliable identification of the perforating vessels and aids in the design of free-style free flaps, where the flaps are designed purely according to the perforator located. The major advantage of free-style free flaps is that an unlimited number of flaps can potentially be designed on much shorter pedicles. The anterolateral thigh flap is the most commonly used perforator flap in head and neck reconstruction. Its use is described in detail, as is use of other less common perforator flaps. This article also describes head and neck reconstruction in a region-specific manner and gives a short-list of suitable flaps based on the location of the defect.

Project description:IntroductionHistorically, there were concerns vasopressors impair free flap outcomes, but recent studies suggest vasopressors are safe. Here we investigate this controversy by (1) evaluating vasopressors' effect on head and neck free-flap survival and surgical complications, and (2) performing soft tissue and bony subset analysis.Patients and methodsPost hoc analysis was performed of a single-blinded, prospective, randomized clinical trial at a tertiary care academic medical center involving patients ≥18 years old undergoing head and neck free flap reconstruction over a 16-month period. Patients were excluded if factors prevented accurate FloTrac™ use. Patients were randomized to traditional volume-based support, or goal-directed support including vasopressor use. Primary data was obtained by study personnel through intraoperative data recording and postoperative medical record review.ResultsForty-one and 38 patients were randomized to traditional and pressor-based algorithms, respectively. Flap survival was 95% (75/79). There was no significant difference between the pressor-based and traditional protocols' flap failure (1/38 [3%] vs. 3/41 [7%], RR 0.36, 95% CI of RR 0.04-3.31, p = .63) or flap-related complications (12/38 [32%] vs. 18/41 [44%], RR 0.72, 95% CI 0.40-1.29, p = .36) Soft tissue flaps had surgical complication rates of 12/30 (40%) and 9/27 (33%) for traditional and pressor-based protocols, respectively. Bony flaps had surgical complication rates of 6/11 (55%), and 3/11 (27%) for traditional and pressor-based protocols, respectively.ConclusionsIntraoperative goal-directed vasopressor administration during head and neck free flap reconstruction does not appear to increase the rate of flap complications or failures.

Project description:ImportanceFree flap surgery is a lengthy procedure with massive tissue destruction and reconstruction, which makes postoperative pulmonary complications (PPCs) a noticeable issue among patients with head and neck cancer. Propofol-based total intravenous anesthesia (TIVA) has better survival outcomes than inhalational anesthesia (INH) in several types of cancer surgery. A previous retrospective study found that patients in the TIVA group had a lower PPC rate, which may be correlated with a lower intraoperative fluid requirement. We hypothesize that the protective effect remains among patients undergoing free flap surgery for head and neck cancer in a prospective and goal-directed fluid therapy setting.ObjectiveTo assess the effect of TIVA vs INH on PPCs in patients undergoing microvascular reconstruction for head and neck cancer.Design, setting, and participantsThis prospective, 2-arm, randomized clinical trial was conducted at a tertiary hospital in Taiwan; a total of 78 patients 18 years and older with American Society of Anesthesiologists physical status classification 1 to 3 who were scheduled for elective free flap surgery under general anesthesia were included. The trial started in October 2017, completed in October 2019, and finished analysis in January 2022.InterventionsPatients were enrolled and randomized to the TIVA or INH group. All patients received goal-directed fluid therapy and hemodynamic management if they had a mean arterial pressure (MAP) below 75 mm Hg or a reduction of 10% from baseline MAP.Main outcomes and measuresThe primary outcome was a composite of PPCs. The secondary outcomes were the differences in intraoperative hemodynamic values (mean arterial pressure, MAP; cardiac index, CI; systemic vascular resistance index, SVRI; and stroke volume variation, SVV).ResultsA total of 70 patients (65 men [93%]; 5 women [7%]) completed the trial; median (IQR) age was 52.0 (48-59) years in the TIVA group and 57.0 (46-64) years in the INH group. The demographic characteristics were similar between the 2 groups, except that patients in the TIVA group had a slightly lower body mass index. Patients in the TIVA group had a lower risk of developing PPCs (unadjusted odds ratio, 0.25; 95% CI, 0.08-0.80). The TIVA group had significantly higher MAP, lower CI, and higher SVRI than the INH group after the third hour of monitoring. The TIVA group showed a relatively stable hourly MAP, CI, SVRI, and SVV across time points, while the INH group showed a more varying pattern. The generalized estimating equation showed no clinical differences in the trend of hemodynamic parameters across time between groups.Conclusions and relevanceIn this randomized clinical trial, using propofol-based TIVA reduced the incidence of PPCs in free flap surgery. This finding may be related to more stable hemodynamic manifestations and a lower total balance of fluid throughout the surgery.Trial registrationClinicalTrials.gov Identifier: NCT03263078.

Project description:BackgroundPostoperative complications (POCs) of moderate-advanced head and neck squamous cell carcinoma (HNSCC) after free flap reconstruction have received little attention. We investigated the risk factors that lead to POCs and their impact on management and prognosis.Patients and methodsA single-center, prospective cohort study was conducted at Beijing Stomatological Hospital on primary HNSCC patients treated between 2015 and 2020.ResultsIn total, 399 consecutive HNSCC patients who underwent radical resection of the primary tumor and free flap reconstruction were enrolled in this study, 155(38.8%) experienced POCs. The occurrence of POCs directly led to worse short-term outcomes and poorer long-term overall survival (P=0.0056). Weight loss before the operation (P=0.097), Tumor site (P=0.002), stage T4b (P=0.016), an ACE-27 index of 2-3 (P=0.040), operation time≥8h (P=0.001) and Clindamycin as antibiotic prophylaxis (P=0.001) were significantly associated with POCs.ConclusionsThe occurrence of POCs significantly leads to worse short-term outcomes and increases the patients' burden.

Project description:Head and Neck osteosarcoma is an uncommon disease. Hitherto, the treatment is surgical resection and survival is influenced by the presence of free margins. However, the dimension of the resection may represent a hurdle for an adequate Quality of Life (QOL). Maxillofacial district is a narrow space where the function, esthetics and patient's relational skills fit together like the gears of a clock. The functional results depend on the type of reconstruction and prosthetic rehabilitation that are both important to guarantee a good aesthetic result and finally increase the patient's self-esteem. This study aims to report our experience about head and neck (HN) osteosarcoma focusing the attention on reconstructive and dental-rehabilitative problems. It is a retrospective study all patients were surgically treated in our department. Subjects with histological diagnosis of HN osteosarcoma, treated between 2005 and 2017 were included. The demographic characteristics, surgical treatment, eventually secondary reconstruction and prosthetic rehabilitation, performed in the same department, have been collected. The QOL was assessed through the EORTC QLQ-H&N35 (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Head and Neck 35) questionnaire. Fifteen patients were enrolled, eight received a free flap microsurgical reconstruction. Dental rehabilitation was performed in five cases and a mobile prosthesis was always delivered. Eighteen implants were inserted in fibula bones for three patients; highly porous implants were used.

Project description:With the recent increase in the use of hip arthroscopy, revision hip arthroscopy also has become more prevalent; nevertheless, it is often complex, and many factors should be considered to achieve a satisfactory clinical outcome. Labral reconstruction or augmentation technique is used in cases of severely deficient acetabular labral tissue to restore the fluid seal mechanism. In cases of previous over-resection of cam impingement, the remplissage technique, used to restore the bony defect of the femoral head-neck junction and preserve the joint seal, is an established technique that has been recently reported in the hip with the use of iliotibial band with the same aim as in the shoulder, filling in of the defect due to healing of the soft tissue to the underlying bony impression. We aim to describe a labrum reconstruction in combination with a remplissage of the femoral head-neck junction with a dermal graft in a patient with recurrent hip pain after hip scope. This combination may improve hip stability and reduced pain after failed hip scope.

Project description:Since the inception of this journal in 1948, the understanding of etiologic factors that contribute to and the treatment of head and neck cancer has evolved dramatically. Advances in surgery, radiation therapy, and chemotherapy have improved locoregional control, survival, and quality of life. The outcomes of these treatment modalities have shifted the focus of curative efforts from radical ablation to preservation and restoration of function. This evolution has been documented in the pages of Cancer for the past 6 decades. This review focuses on the evolution of treatment approaches for head and neck cancer and future directions while recognizing the historic contributions recorded within this journal.
