RESUMO
PURPOSE: The purpose of the present study was to investigate the differences in postoperative thrombosis and flap failure between internal jugular vein (IJV) system anastomosis and external jugular vein (EJV) system anastomosis in free flaps for the reconstruction of head and neck defects. MATERIALS AND METHODS: We searched PubMed, Web of Science, EMBASE, Chinese BioMedical Literature Database, and other databases until March 2019 for studies that had reported data for anastomosis for the 2 different venous systems in the microvascular free-flap reconstruction of head and neck defects. We assessed thrombosis and flap failure in patients undergoing anastomosis of the IJV system and patients undergoing anastomosis of the EJV system. RESULTS: Nine studies with a total of 2051 patients with venous anastomosis were included in the present meta-analysis. IJV system anastomosis showed a significantly lower incidence of venous thrombosis than did the EJV system (relative risk [RR], 0.55; 95% confidence interval [CI], 0.37 to 0.82). Eight studies were included in the analysis of the flap failure rate, which showed a lower failure rate for the IJV system anastomosis than for the EJV system (RR, 0.59; 95% CI, 0.35 to 1.00). CONCLUSIONS: The incidence of thrombosis and flap failure after venous anastomosis in the IJV system was lower than that in the EJV system. The results from the present study have shown that the IJV system should be the first choice for venous anastomosis in the reconstruction of free flaps.

PURPOSE: This study focused on quality of life for patients in northeast China who underwent oral cancer resection directly before flap reconstruction. In addition, this study compared differences among the radial forearm free flap (RFFF), ulnar forearm free flap (UFFF), and anterolateral thigh flap (ALTF) for defect reconstruction. MATERIALS AND METHODS: To assess patients' quality of life, the University of Washington Quality of Life and 14-item Oral Health Impact Profile (OHIP-14) questionnaires were completed 6 months after reconstruction. RESULTS: The flap size of the ALTF group was much larger than that of the UFFF and RFFF groups. The appearance score of the ALTF group was markedly higher than that of the UFFF and RFFF groups, whereas these groups had a much higher swallowing score than the ALTF group. Furthermore, the ALTF group had much lower social disability OHIP-14 scores than the RFFF group. CONCLUSIONS: The results indicate that all 3 reconstruction methods are similar, but that the ALTF has a slight advantage over the UFFF and RFFF.

PURPOSE: The main aim of this article is to compare the complication rate associated with the use of miniplates versus reconstruction plates in vascularized osteocutaneous flap reconstruction of the mandible. PATIENTS AND METHODS: The authors searched PubMed, Web of Science, EMBASE, Chinese BioMedical Literature Database (CBM), Cochrane Library, and clinicaltrials.gov up to September 2017 to identify studies that compared the complication rate of miniplates versus reconstruction plates in patients undergoing mandibular reconstruction. Two reviewers individually extracted the data and performed a quality assessment. Plate exposure, plate fracture/removal, infection, and overall complications were evaluated. RESULTS: Five studies with 511 cases were included in our analysis. No significant difference was found between the groups. However, the reconstruction plate led to fewer overall complications and plate exposure postoperatively than did the miniplate. CONCLUSION: Our meta-analysis suggests that miniplates and reconstruction plates are suitable for mandibular reconstruction with a vascularized osteocutaneous flap.

OBJECTIVE: This study aimed to compare the complications at the donor site of supra- versus subfascially harvested anterolateral thigh perforator free flaps. METHOD: We searched PubMed, Web of Science, EMBASE, the Chinese BioMedical Literature Database (CBM) and the Cochrane Library until December 31, 2018, to identify studies that compared complications at the donor site of the supra- versus subfascially raised anterolateral thigh perforator free flaps. Two authors individually extracted the data and performed the quality assessments. Skin grafting, the rate of poor healing in the donor site, dysfunction at the donor site and sensory functions at the donor site were evaluated. RESULT: Seven studies with a total of 525 patients were included in our analysis. No significant differences were found regarding skin grafting and sensory functions between the 2 groups. However, in regard to the rate of poor healing and dysfunction at the donor site, the SPF group showed significantly better outcomes than the SBF group after the operation. CONCLUSION: Our meta-analysis suggested that, in regards to skin grafting and sensory recovery, the SPF and SBF groups were similar. With regard to donor site healing and functional recovery, the SPF group exhibited better outcomes than the SBF group.
