RESUMEN

Placing dental implants in microvascular bone free flaps used for reconstructing the mandible or maxilla has been previously reported. However, there is scarce information available on the restorative protocol using short dental implants placed in a deep circumflex iliac artery (DCIA) microvascular free flap and the rationale behind it. This case report describes a 18-year-old patient referred to the hospital for numbness and dull pain of the left mandible, which she observed for three months. The patient underwent mandible resection and reconstruction using the DCIA free flap due to "giant cell lesion" on the left side of the mandibular angle. Short dental implants were placed and prosthetic reconstruction of the dentition involved in the resection was performed in a young patient with two integrated abutment crowns. The placement of short dental implants did not negatively affect the vascular pedicle and vitality of free flap. In our case report, two years after the healing, excellent aesthetic and function were accomplished with the DCIA flap followed by restoration with short implants.

RESUMEN

OBJECTIVE: There is a trend towards nonintensive care unit (ICU) or specialty ward management of select patients. Here, we examine postoperative outcomes for patients transferred to a general ward following microvascular free flap (FF) reconstruction of the head and neck. STUDY DESIGN: Retrospective quality control study. SETTING: Single tertiary care center. METHODS: Consecutive patients who underwent FF of the head and neck before and after a change in protocol from immediate postoperative monitoring in the ICU ("Pre-protocol") to the general ward setting ("Post-protocol"). Outcomes included overall length of stay (LOS), ICU LOS, FF compromise, and postoperative complications. RESULTS: A total of 150 patients were included, 70 in the pre-protocol group and 80 in the post-protocol group. There were no significant differences in age, sex, comorbidities, tumor stage, or type of FF. Mean LOS decreased from 8.18 to 7.68 days (P = .4), and mean ICU LOS decreased significantly from 5.2 to 1.7 days (P < .01). There were no significant differences in postoperative or airway-related complications (P = .6) or FF failure rate (2.9% vs 2.6%, P > .9). There was a non-significant increase in ancillary consults in the post-protocol group (45% vs 33%, P = .13) and a significant increase in rapid response team calls, a nurse-driven safety net for abnormal vitals or mental status (19% vs 3%, P = .003). CONCLUSION: We show the successful implementation of a protocol shifting care of FF patients from the ICU to a general ward postoperatively, suggesting management on the floor with less frequent flap monitoring is safe and conserves ICU beds. Additional teaching and familiarity with these patients may over time reduce the rapid response calls.

RESUMEN

There is limited information regarding implant and prosthetic survival after osseous microvascular free flap (OMFF). This case series aims to describe the placement of short and extra short implants in osseous microvascular free flaps to support prostheses, and present an up to 40-month retrospective follow-up. Short and extra short dental implants were placed in six fibula free flaps (FFF) and in two microvascular deep circumflex iliac artery (DCIA) flaps. In total, 27 short and extra short dental implants have been placed into two different types of free flaps. Kaplan-Meyer (K-M) survival analyses were performed to evaluate the survival and success outcomes of implants and prostheses. Out of the eight patients reconstructed with free flap, five were rehabilitated with prostheses, one patient has a temporary prosthesis, and two patients are in the process of prosthetic rehabilitation. Twenty-seven implants were followed up for up to 40 months, and K-M analyses showed 100% implant survival probability (95% confidence interval: 100%), while the implant success probability was 91.0% (95% confidence interval: 68.6-97.7%). Short and extra short dental implants placed in OMFF presented high survival and success rates in a retrospective case series after up to 40 months.

RESUMEN

Importance Free tissue transfer for reconstruction of the head and neck requires complicated repair of complex anatomy. The posterior tibial flap is a free tissue flap that has viability and versatility to be used for complex reconstructions that is not offered by other free flaps. OBJECTIVE: The posterior tibial artery flap is a perforator flap which is found between the flexor digitorum longus and the soleus. It has been described as both a pedicled flap for lower extremity reconstruction as well as a free flap, including for head and neck reconstruction. Limited data exists on the subject in the English literature. The objective of this study is to present our experience with the flap in the head and neck. DESIGN: Retrospective review of cases from a single institution between October 2019 and May 2023. Primary indications included patients whose defects were felt to be larger than a conventional radial forearm free flap that were not well served by the anterolateral thigh flap, either because of body habitus or room for the associated muscle. SETTING: Tertiary academic hospital system performing free tissue transfer reconstruction of within the head and neck. RESULTS: Fifteen patients underwent posterior tibial artery free flap during the study period. Indications for flap reconstruction included oral cavity, tongue, oropharynx and skin of the scalp and forehead. Flap size ranged from 24cm2 to 143cm2. Only one flap failure was observed. Flap harvest time was universally under forty-six minutes, and as little as thirty-two. CONCLUSION: The posterior tibial artery flap is a useful option in head and neck reconstruction. It provides an intermediary in size and bulk between the radial forearm and the anterolateral thigh flap. Additionally, it provides a straightforward harvest with minimal donor site morbidity.

RESUMEN

BACKGROUND AND OBJECTIVES: The resorption of flap's volume can be frequently observed in the transplantation of microvascular free flaps, which could significantly affect postoperative function. Therefore, it's essential to comprehend the postoperative flap volume and the mechanisms behind before making clinical decisions. METHODS: Literature search was conducted from database on PubMed, EMBASE, Cochrane Library, Chinese database and Google Scholar. A random effects model meta-analyses and descriptive systematic review were performed. RESULTS: The search identified 420 articles, of which 9 studies included in meta-analysis and 14 studies included in descriptive systematic review. Postoperative flap volume maintenance rate is used to represent the volume change. The pooled mean postoperative flap volume maintenance rate was 62.82 % for soft tissue flap (95 %CI: 58.83 to 66.82, p = 0.076, I2=56.3 %) and 85.96 % for bone flap (95 %CI: 84.19 to 87.73, p = 0.274, I2=20.4 %). Weight loss, muscle atrophy, and decreased serum albumin levels are risk factors for postoperative volume reduction of soft tissue flaps. The bone resorption rate of bone flaps in women is higher than that in men. CONCLUSION: When designing microvascular free flaps for oral and maxillofacial surgery, soft tissue flaps should consider an anticipated postoperative shrinkage of 37 %, while bone flaps should consider an anticipated postoperative shrinkage of 14 %.

RESUMEN

INTRODUCTION: Coronavirus disease 2019 (COVID-19) affects the vascular system, subjecting patients to a hypercoagulable state. This is of particular concern for the success of microvascular free flap reconstruction. This study aims to report head and neck free flap complications in patients with COVID-19 during the perioperative period. We believe these patients are more likely to experience flap complications given the hypercoagulable state. METHODS: This is a multi-institutional retrospective case series of patients infected with COVID-19 during the perioperative period for head and neck free flap reconstruction from March 2020 to January 2022. RESULTS: Data was collected on 40 patients from 14 institutions. Twenty-one patients (52.5%) had a positive COVID-19 test within 10 days before surgery and 7 days after surgery. The remaining patients had a positive test earlier than 10 days before surgery. A positive test caused a delay in surgery for 16 patients (40.0%) with an average delay of 44.7 days (9-198 days). Two free flap complications (5.0%) occurred with no free flap deaths. Four patients (10.0%) had surgical complications and 10 patients had medical complications (25.0%). Five patients (12.5%) suffered from postoperative COVID-19 pneumonia. Three deaths were COVID-19-related and one from cancer recurrence during the study period. CONCLUSION: Despite the heightened risk of coagulopathy in COVID-19 patients, head and neck free flap reconstructions in patients with COVID-19 are not at higher risk for free flap complications. However, these patients are at increased risk of medical complications. LEVEL OF EVIDENCE: 4 Laryngoscope, 2023.

RESUMEN

BACKGROUND: The trend in postoperative care for free flap patients is to deescalate from routine ICU admission into a specialty recovery unit. This study aims to investigate the predictive parameters in a routine perioperative clinical assessment that are expected to be directly correlated with prolonged ICU length of stay in at-risk patients who received oral reconstructive surgery for squamous cell carcinoma (OSCC). METHODS: All patients who underwent ablative surgery for OSCC with free flap reconstruction and were managed in the ICU were included in this study. The primary outcome was ICU-length of stay. Perioperative, operative and postoperative parameters were analyzed using single test ( t-test, ANOVA analysis, correlation coefficients, effect size) and multivariate regression test. The P-value was set as < 0.005 to be considered statically significant. RESULTS: The study included 136 homogeneous patients, with a mean ICU length of stay of 4.5 (± 4.43 day). Patients with pre-operative positive renal dysfunction (P = 0.004), peripheral vascular disease (P < 0.001), postoperative complications (P = 0.028) or positive heart failure class III (P < 0.001 ) were recognized as at-risk patients for a significantly longer ICU length of stay. CONCLUSION: Patients with perioperative severe renal dysfunction, peripheral vascular disease, postoperative complication or high NYHA class are prone to have a significantly longer ICU length of stay. Several factors were considered as confounders contributing to increased ICU management time in combination with other variables. Additionally, in highly risk patient, the presence of the highly trained medical support, including the appropriate nursing care, is more critical than those patients without these risk factors.

RESUMEN

BACKGROUND: Postoperative delirium (POD) is a serious complication in patients undergoing microvascular head and neck reconstruction. Whether intraoperative and postoperative blood pressure regulation are risk factors for POD remains unclear. This study aimed to highlight the relationships between intraoperative and postoperative blood pressure regulation and POD in microvascular head and neck reconstruction. METHODS: Data from 433 patients who underwent microvascular head and neck reconstruction at our department of oral and maxillofacial surgery between 2011 and 2019 were retrospectively analyzed. The 55 patients with POD were matched with 55 patients without POD in terms of tracheotomy, flap type, and flap location, and the intraoperative and postoperative systolic and mean blood pressure values were compared between the two groups. RESULTS: Patients with POD showed lower intraoperative and postoperative minimum mean arterial pressure (MAP) values than patients without POD (60.0 mmHg vs. 65.0 mmHg, p < 0.001; and 56.0 mmHg vs. 62.0 mmHg, p < 0.001; respectively). A lower intraoperative minimum MAP value was identified as predictor for POD (odds ratio [OR] 1.246, 95% confidence interval [CI] 1.057-1.472, p = 0.009). The cut-off value for intraoperative MAP for predicting POD was ≤ 62.5 mmHg (area under the curve [AUC] 0.822, 95% CI 0.744-0.900, p < 0.001). CONCLUSIONS: Maintaining a stable intraoperative minimum MAP of > 62.5 mmHg could help to reduce the incidence of POD in microvascular head and neck reconstruction.

RESUMEN

Aim: To evaluate the current role of pectoralis major (PM) flap including the reasons for selecting it over free flaps. Materials and methods: All patients who underwent PM flap at Apollo Hospitals Ahmedabad during the 3-year period from January 2020 to December 2022 were included. Patient demographics, tumour characteristics and complications were studied and reasons for selecting pectoralis major flap were analyzed. Data was entered in Microsoft excel spreadsheet and analyzed using online statistical calculators. The p value of < 0.05 was considered statistically significant. Results: 57 patients underwent reconstruction with PM flap while 154 patients underwent free flap reconstruction. 54 were male and 3 were female. Median age was 51 years. PM flap was used for intraoral lining in 25 patients, and it was bilobed in 26 patients with full thickness cheek defect. Most common complication was wound infection seen in 10 patients. 5 patients developed marginal necrosis of the flap and 5 had donor site wound dehiscence. No complete flap loss was seen. During the same period, 15/154 (9.74%) patients with free flaps developed complete flap necrosis and this was statistically significant (p = 0.012). Reasons for choosing PM flap were also analyzed. 14 patients had major comorbidities, 18 had extensive disease, in 5 patients it was used for salvage post free flap failure, while 10 previously treated patients had unavailability of suitable vessels for anastomosis. 12 patients underwent PM flap due to financial constraints. Conclusion: Thus, PM flap is not obsolete and continues to maintain its place in head and neck reconstruction.

RESUMEN

OBJECTIVE: Pedicled flaps (PFs) have historically served as the preferred option for reconstruction of large chest wall defects. More recently, the indications for microvascular-free flaps (MVFFs) have increased, particularly for defects in which PFs are inadequate or unavailable. We sought to compare oncologic and surgical outcomes between MVFFs and PFs in reconstructions of full-thickness chest wall defects. METHODS: We retrospectively identified all patients who underwent chest wall resection at our institution from 2000 to 2022. Patients were stratified by flap reconstruction. End points were defect size, rate of complete resection, rate of local recurrence, and postoperative outcomes. Multivariable analysis was performed to identify factors associated with complications at 30 days. RESULTS: In total, 536 patients underwent chest wall resection, of whom 133 had flap reconstruction (MVFF, n = 28; PF, n = 105). The median (interquartile range) covered defect size was 172 cm2 (100-216 cm2) for patients receiving MVFF versus 109 cm2 (75-148 cm2) for patients receiving PF (P = .004). The rate of R0 resection was high in both groups (MVFF, 93% [n = 26]; PF, 86% [n = 90]; P = .5). The rate of local recurrence was 4% in MVFF patients (n = 1) versus 12% in PF patients (n = 13, P = .3). Postoperative complications were not statistically different between groups (odds ratio for PF, 1.37; 95% confidence interval, 0.39-5.14]; P = .6). Operative time >400 minutes was associated with 30-day complications (odds ratio, 3.22; 95% confidence interval, 1.10-9.93; P = .033). CONCLUSIONS: Patients with MVFFs had larger defects, a high rate of complete resection, and a low rate of local recurrence. MVFFs are a valid option for chest wall reconstructions.

RESUMEN

BACKGROUND: Complex scalp wounds with cranial/dural involvement are challenging to reconstruct. Successful reconstruction can be achieved with cranial implants/hardware and free flap coverage. Wounds can breakdown and require revision procedures. We addressed reconstructive outcomes of different implants requiring free flaps. OBJECTIVE: To determine the factors associated with implant exposure. DESIGN: Multi-institutional retrospective review of 82 patients, 2000-2020, repaired with cranial implants and free flap coverage. RESULTS: Implant exposure occurred in 13/82 (16%) reconstructions. Flap atrophy or thinning leading to implant exposure occurred in 11/82 (13%) reconstructions, including partial flap atrophy OR 0.05 (95% CI 0.0-0.35) and total flap atrophy OR 0.34 (95% CI 0.02-19.66). Revision surgeries that occurred subsequent to flap reconstruction were also associated with implant exposure (OR 0.02 (95% CI 0.0-0.19)). Implant exposure was not associated with radiation therapy, patient health history, implant type, flap type, or postoperative complications. CONCLUSIONS: Implant exposure is associated with free flap atrophy, leading to inadequate implant coverage and the need for revision surgeries. Completing reconstruction with adequate soft tissue bulk and coverage and avoiding revision surgery may decrease the risk for implant exposure over time.

RESUMEN

OBJECTIVES: Head and neck cancer patients that require major reconstruction often have advanced-stage disease. Discharge disposition of patients can vary and impact time to adjuvant treatment. We sought to examine outcomes in patients discharged to skilled nursing facilities (SNF) compared to those discharged home, including the impact on adjuvant therapy initiation and treatment package time (TPT). METHODS: Patients with head and neck squamous cell carcinoma treated with surgical resection and microvascular free flap reconstruction from 2019 to 2022 were included. Retrospective review was conducted to evaluate the impact of disposition on time to radiation (RT) and TPT. RESULTS: 230 patients were included, with 165 (71.7%) discharged to home and 65 (28.3%) discharged to SNF. 79.1% of patients were recommended adjuvant therapy. Average time to RT was 59 days for patients discharged to home compared to 70.1 days for patients discharged to SNF. Disposition was an independent risk factor for delays to starting RT (p = 0.03). TPT was 101.7 days for patients discharged to home versus 112.3 days for those who discharged to SNF. Patients discharged to SNF had higher rates of readmission (p < 0.005) compared to patients discharged home in an adjusted multivariate logistic regression. CONCLUSIONS: Patients discharged to an SNF had significantly delayed time to initiation of adjuvant treatment and higher rates of readmission. Timeliness to adjuvant treatment has recently been established as a quality measure, thus identifying delays to adjuvant treatment initiation should be a priority. LEVEL OF EVIDENCE: 3 Laryngoscope, 133:2977-2983, 2023.

RESUMEN

This study aimed to evaluate the use of microvascular free flaps (MFF) in oral and maxillofacial surgery (OMFS) in Germany, Austria, and Switzerland. A dynamic online questionnaire, using 42-46 questions, was sent to OMF surgeons based in hospitals in Germany, Austria, and Switzerland. The questionnaire was evaluated internally and externally. Aside from general information, data were collected on organizational aspects, approaches, MFF types and frequency, presurgical planning, intraoperative procedures, perioperative medications, flap monitoring, and patient management. Participants mostly performed 30-40 MFF each year (11/53). Most stated that the COVID-19 pandemic did influence MFF frequency (25/53) to varying extents. Radial forearm flap was most frequently used (37/53), followed by ALT (5/53), and fibula flap (5/53). Primary reconstruction was performed by most participants (35/48). Irradiated bony transplants were mostly used for implant placement after 12 months (23/48). Most participants (38/48) used reconstruction plates, followed by miniplates (36/48), PSI reconstruction (31/48), and PSI miniplates (10/48). Regarding the postoperative use of anticoagulants, low-molecular-weight (37/48) and unfractioned heparins (15/48) were widely used, most often for 3-7 days (26/48). Clinical evaluation was mostly preferred for flap monitoring (47/48), usually every 2 h (34/48), for at least 48 h (19/48). Strong heterogeneity in MFF reconstructions in OMFS was found, especially regarding the timepoints of reconstruction, types of osteosynthesis, and postoperative MFF management. These findings provide the chance to further compare the different treatment algorithms regarding relevant MFF aspects, such as postoperative management. This could create evidence-based treatment algorithms that will further improve the clinical outcomes in MFF reconstructions.

RESUMEN

OBJECTIVE: To evaluate harms reporting in systematic reviews (SRs) of microvascular free flap (MFF) in head and neck reconstruction. DATA SOURCES: This cross-sectional analysis included searches from the following major databases from 2012 to June 1, 2022: MEDLINE (Pubmed and Ovid), Embase, Epistemonikos, and the Cochrane Database of Systematic Reviews. REVIEW METHODS: In a masked duplicate manner, screening was performed using Rayyan, and data were extracted using a pilot-tested Google form. A MeaSurement Tool to Assess systematic Reviews-2 (AMSTAR-2) was used to appraise the methodological quality of reviews and the corrected covered area was calculated to detect primary study overlap across all reviews. Reviews were then grouped in pairs of 2, called dyads, and the corrected covered area was calculated again for each individual dyad. Dyads with high overlap (≥50%) were further investigated for the accuracy of harms reporting. RESULTS: Our initial search yielded 268 records, with 50 SRs meeting the inclusion criteria. A total of 46 (92%) of the included reviews demonstrated 50% or more adherence to the items assessed in our harms checklist. Our corrected covered area tool revealed 0.6% primary study overlap across all reviews, and 1 dyad with high overlap (≥50%). No statistically significant relationship was observed between the completeness of harms reporting and reviews listing harms as a primary outcome, reviews reporting adherence to Preferred Reporting Items of Systematic Reviews and Meta-Analyses, or a review's AMSTAR rating. CONCLUSION: This study identifies how harms reporting in SRs of MFF reconstruction of the head and neck can be improved and provides suggestions with the potential to mitigate the paucity in current literature.

RESUMEN

Background Polycythemia vera (PV) is a myeloproliferative disease with overproduction of erythrocytes, leukocytes, and platelets causing an increased risk of both thrombosis and hemorrhage. There are limited reports and no established guidelines for managing such patients undergoing reconstructive surgery. Methods We present four patients with PV and head and neck cancer who required reconstruction after resection and provide a review of the current literature. Results Preoperatively, patients on cytoreductive therapy continued with their treatment throughout their hospital course and had hematologic parameters normalized with phlebotomy or transfusions if needed. Two patients who underwent free flap surgery (cases 1 and 2) had postoperative courses complicated by hematoma formation and persistent anemia, requiring multiple transfusions. Cases 3 and 4 (JAK2+ PV and JAK2- PV, respectively) underwent locoregional flap without postoperative complications. Conclusion Concomitant presentation of PV and head and neck cancer is uncommon and presents unique challenges for the reconstructive surgeon. Overall, we recommend that patients should have hematologic parameters optimized prior to surgery, continue ruxolitinib or hydroxyurea, and hold antiplatelet/anticoagulation per established department protocols. It is essential to engage a multidisciplinary team involving hematology, head and neck and reconstructive surgery, anesthesia, and critical care to develop a standardized approach for managing this unique subset of patients.

RESUMEN

INTRODUCTION: Reconstruction of a surgical defect is an important part of the management of oral cancers. Microvascular free flap construction provides better functional and cosmetic outcomes. METHODS: Between 2014 and 2020, some 524 patients underwent microvascular reconstruction. Comorbidity variables were scored using the Charlson Comorbidity Index (CCI). Complications were recorded using Clavien-Dindo criteria. RESULTS: Eighty-three (15.84%), 339 (64.69%) and 102 (19.47%) patients underwent free radial forearm flap, free anterolateral thigh flap and free fibula osteocutaneous flap (FFOCF), respectively. Clavien-Dindo complications of grade III and above were seen in 39 (7.44%) patients. Total flap loss was seen in 18 patients and of these, 16 were salvaged using alternative free flaps or pedicled flaps. On univariate analysis, overall and major complication rates were higher in FFOCF (p=0.171). Major complications significantly more common in patients with a CCI score >4 (p=0.001). Patients aged >65 years had higher rates of complications (p=0.03). CONCLUSION: Microvascular free tissue transfer is a reliable, safe and gold standard modality in surgical reconstruction and can be replicated in non-institutional settings.

RESUMEN

PURPOSE: Despite microvascular free tissue transfer being the mainstay of care in the reconstruction of larger maxillofacial defects, a significant number of patients experience postoperative complications due to impaired blood supply of the flap. In this context, the early influence of recipient bed perfusion remains unclear, but there is evidence that it is associated with free flap viability immediately after surgery. METHODS: We analyzed flap and recipient bed perfusion within the first 2 weeks after surgery by using the oxygen-to-see device. One hundred ninety-one patients who underwent free flap surgery in our department were included. RESULTS: Flow parameters were higher and postoperative complications were less frequent in radial forearm free flaps compared to any other type of flap. Flow parameters of the recipient bed were higher than transferred tissue at all times, implicating flap autonomization is not completed within 2 weeks. Previous radiotherapy significantly decreased flow parameters of the recipient bed but not of the flaps. Furthermore, irradiated patients with postoperative complications were found to have reduced flow parameters of their recipient bed compared to non-irradiated patients with postoperative complications. CONCLUSION: We conclude that monitoring of recipient bed perfusion is useful for detecting flap compromise of irradiated patients in the early postoperative period.

RESUMEN

Arteriovenous malformations are high-flow congenital vascular malformations that are characterized by abnormal connections between arteries and veins across an abnormal capillary bed. The head and neck region is the most common location for extracranial arteriovenous malformations. Due to their highly invasive, aggressive, and locally destructive nature, arteriovenous malformations are difficult to treat, and management through a multimodal, multidisciplinary approach is recommended. The mainstay of treatment is embolization and surgical excision. With the advent of genetic research, adjuvant targeted medical therapy is starting to play a larger role. Successful surgical treatment with or without embolization requires removal of the nidus. Large, focal, or diffuse lesions involving multiple anatomic areas usually necessitates surgical reconstruction. Free tissue transfer has many advantages over more conservative methods with restoration of function and contour. Herein, the authors describe the surgical treatment and reconstruction in head and neck arteriovenous malformations.

RESUMEN

Purpose: The purpose of this study was to compare Pectoralis major myocutaneous flap (PMMC) and Free flaps for reconstruction of post ablative defects in patients undergoing treatment for oral squamous cell carcinoma and to understand the reasons for choosing each from a developing nation perspective. Material and methods: In the present study, a retrospective study was conducted of the patients treated by either free flaps or PMMC flaps for reconstructive procedures over a five year period in the Department of Oral and Maxillofacial Surgery, Shri Guru Ram Das Institute of Dental Sciences and Research. Results: Out of 90 PMMC flaps, 44 patients (48.8%) had reconstruction due to lack of micro vascular facility at the center, in 39 patients (43.3%) due to financial constraints and in 7 patients (7%) due to associated comorbities. The overall complication rate in PMMC group was 30% as compared to 28% in Free Flap group. Total flap loss was seen in 3 flaps (2 microvascular and 1 PMMC) while marginal necrosis of skin paddle was seen in 12 patients (13%) in the PMMC group. Conclusion: Though, the selection of PMMC flap over free flap was influenced by many factors, results of this study suggest that PMMC flap still has a major role in post-ablative defect reconstruction even in this era of free flaps, especially in developing countries like India.
