Objectives Osseous microvascular free tissue transfer (MFTT) is the gold standard for reconstruction for most segmental mandibulectomy defects. The most common osseous MFTT utilized in reconstruction is the fibular, scapular, and osteocutaneous radial forearm (OCRF) free flap. We evaluated postoperative bone union as well as clinical complications following MFTT and the impact of various patient and reconstructive characteristics, including type of osseous MFTT. Study Design Retrospective cohort study. Setting Tertiary care academic hospital. Methods This study examined patients who underwent osseous MFTT for mandibular defects from January 2017 to January 2019. Results An overall 144 osteotomies in 58 patients were evaluated. Of the 144 junctions, 28 (19.4%) showed radiographic nonunion. Patients who underwent preoperative (odds ratio [OR] = 0.30, P = .027) and postoperative (OR = 0.28, P = .003) radiation had a significantly lower bone union score. Time from surgery to postoperative imaging was associated with higher bone union scores (OR = 1.07, P = .024). When bone union scores were compared among types of MFTT, fibular (OR = 5.62, P = .008) and scapular (OR = 4.69, P = .043) MFTT had significantly higher scores than OCRF MFTT. Twelve (20.7%) patients had postoperative complications. There was no statistically significant correlation between clinical complications and various variables, including type of osseous MFTT. Conclusion Pre- and postoperative radiation and time from surgery have an impact on bone union. Regarding the type of MFTT, fibular and scapular MFTT appeared to have higher bone union when compared with OCRF. There was no impact of bone union or type of osseous MFTT on clinical complications.

We conducted a retrospective case review at our tertiary care academic medical center to assess the long-term results of microvascular free-tissue transfer to achieve facial reanimation in 3 patients. These patients had undergone wide-field parotidectomy with facial nerve resection. Upper facial reanimation was accomplished with a proximal facial nerve–sural nerve graft, and lower facial movement was achieved through proximal facial nerve–long thoracic (serratus muscle) nerve anastomosis. Outcomes were determined by grading postoperative facial nerve function according to the House-Brackmann system. All 3 patients were able to close their eyes independent of lower facial movement, and all 3 had achieved House-Brackmann grade III function. We conclude that reanimating the paralyzed face with microvascular free-tissue transfer provides anatomic coverage and mimetic function after wide-field parotidectomy. Synkinesis is reduced by separating upper-and lower-division reanimation.

Abstract Background Since the spreading of SARS-CoV-2 from China, all deferrable medical activities have been suspended, to redirect resources for the management of COVID patients. The goal of this retrospective study was to investigate the impact of COVID-19 on head and neck cancers’ diagnosis in our Academic Hospital. Methods A retrospective analysis of patients treated for head and neck cancers between March 12 and November 1, 2020 was carried out, and we compared these data with the diagnoses of the same periods of the 5 previous years. Results 47 patients were included in this study. We observed a significative reduction in comparison with the same period of the previous 5 years. Conclusions Our findings suggest that the COVID-19 pandemic is associated with a decrease in the number of new H&N cancers diagnoses, and a substantial diagnostic delay can be attributable to COVID-19 control measures.

Abstract Background Lower extremity defects often require free tissue transfer due to a paucity of local donor sites. Locoregional perforator-based flaps offer durable, single-stage reconstruction while avoiding the pitfalls of microsurgery. Multiple harvest techniques are described, yet few studies provide outcome comparisons. Specifically, no study has examined the impact of perforator flap pedicle skeletonization on reconstructive outcomes. This systematic review characterizes technique and impact of pedicle skeletonization on perforator-based fasciocutaneous flaps of the lower extremity. Methods PubMed, Scopus, and the Cochrane Central Register of Controlled Trials were reviewed for literature examining perforator-based fasciocutaneous flaps from knee to ankle, from January 2000 through November 2018. The Preferred Reporting Items for Systematic Reviews-Individual Participant Data (PRISMA-IPD) structure was used. Results Thirty-six articles were included for quantitative analysis. Of 586 flaps, 365 were skeletonized (60.1%) with 58 major (9.9%) and 19 minor complications (3.2%). With skeletonization, overall reoperative rate was higher (odds ratio [OR]: 9.71, p = 0.004), specifically in propeller (OR: 12.50, p = 0.004) and rotational flaps (OR: 18.87, p = 0.004). The complication rate of rotational flaps also increased (OR: 2.60, p = 0.04). Notably, skeletonization reduced complications in flaps rotated 90 degrees or more (OR: 0.21, p = 0.02). Reoperative rate of distal third defects (OR: 14.08, p = 0.02), flaps over 48 cm2 (OR: 33.33, p = 0.01), and length to width ratios over 1.75 (OR: 7.52, p = 0.03) was increased with skeletonization. Skeletonization increased complications in traumatic defects (OR: 2.87, p = 0.04) and reduced complications in malignant defects (OR: 0.10, p = 0.01). Conclusion Pedicled, perforator-based flaps can provide a reliable locoregional alternative to free tissue transfer for lower extremity defects. Though skeletonization increased the overall reoperative rate, the complication rate for flaps with 90 degrees or more of rotation was significantly reduced. This suggests skeletonization should be considered when large rotational movements are anticipated to reduce complications that can arise from pedicle compression and venous congestion.

Background: Emergency department (ED) overcrowding is associated with a broad spectrum of poor medical outcomes, including medical errors, mortality, higher rates of leaving without being seen, and reduced patient and physician satisfaction. The largest contributor to overcrowding is access block – the inability of admitted patients to access in-patient beds from the ED. One component to addressing access block involves streamlining the decision process to rapidly determine which hospital service will admit the patient. Aim Statement: As of Sep 2011, admission algorithms at our institution were supported and formalised. The pancreatitis algorithm clarified whether general surgery or internal medicine would admit ED patients with pancreatitis. We hypothesize that this prior uncertainty delayed the admission decision and prolonged ED length of stay (LOS) for patients with pancreatitis. Our project evaluates whether implementing a pancreatitis admission algorithm at our institution reduced ED time to disposition (TTD) and LOS. Measures & Design: A retrospective review was conducted in a tertiary care academic hospital in Montreal for all adult ED patients diagnosed with pancreatitis from Apr 2010 to Mar 2014. The data was used to plot separate run charts for ED TTD and LOS. Serial measurements of each outcome were used to monitor change and evaluate for special cause variation. The mean ED LOS and TTD before and after algorithm implementation were also compared using the Student's t test. Evaluation/Results: Over four years, a total of 365 ED patients were diagnosed with pancreatitis and 287 (79%) were admitted. The mean ED LOS for patients with pancreatitis decreased following the implementation of an admission algorithm (1616 vs. 1418 mins, p = 0.05). The mean ED TTD was also reduced (1171 vs. 899 mins, p = 0.0006). A non-random signal of change was suggested by a shift above the median prior to algorithm implementation and one below the median following. Discussion/Impact: This project demonstrates that in a busy tertiary care academic hospital, an admission algorithm helped reduce ED TTD and LOS for patients with pancreatitis. This proves especially valuable when considering the potential applicability of such algorithms to other disease processes, such as gastrointestinal bleeding and congestive heart failure, among others. Future studies demonstrating this external applicability, and the impact of such decision algorithms on physician decision fatigue and within non-academic institutions, proves warranted.

The terms free flap and free tissue transfer are synonymous used to describe the movement of tissue from one site on the body to another. "Free" implies that the tissue, along with its blood supply, is detached from the original location (donor site) and then transferred to another location (recipient site). However, studies are still going on about the different aspects of its success and failure. The present case report is one such step to share our experience. In this case report successful microvascular free tissue transfer was possible With the increase in experience we can expect increased success rate as well.
