RESUMO
BACKGROUND: With the gradual popularity of relatively novel medial sural artery perforator flap (MSAPF), robust studies are needed to compare the surgical outcomes of MSAPF versus multiple free soft flaps (MFSFs) to verify the advantages and disadvantages of MSAPF. METHODS: The authors searched PubMed, Web of Science, EMBASE, Cochrane Library, Chinese BioMedical Literature Database (CBM), and China National Knowledge Infrastructure (CNKI) until September, 2020, to identify studies that compared surgical outcomes of MSAPF and MFSFs. Two authors followed the PRISMA guidelines, individually extracted the data and performed the quality assessments. Survival rate of flaps, satisfaction degree of patients in recipient and donor site, skin grafting, and morbidity of recipient and donor site were evaluated. RESULTS: A total of 441 cases from 7 studies were included in our analysis. No significant differences were found regarding survival rate of flaps, recipient morbidity, and recipient satisfaction degree between the 2 groups. However, MSAPF group was significantly superior to MFSFs group in terms of skin grafting, morbidity, and satisfaction degree of donor site. CONCLUSION: Our meta-analysis showed that the MSPAF and MFSFs groups were similar in terms of survival rate of flaps, recipient morbidity, and recipient satisfaction degree. Medial sural artery perforator flap group was superior to MFSFs group in terms of morbidity and satisfaction degree of donor site. The results may prove that MSAPF is gaining popularity for a reason and is a good choice for repairing soft tissue defects.

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.

BACKGROUND: Adequate flap volume is key to maintaining oral function after oral cancer surgery. This study aimed to evaluate changes in radial forearm free flap (RFFF) volumes after 1 year of follow-up following ablative tumor surgery in the head and neck. METHODS: A prospective study that recorded the clinical data of 20 patients with head and neck cancer who underwent RFFF reconstruction. Magnetic resonance (MR) and Mimics Research 19.0 software were used to measure the RFFF volumes at 1, 3, 6, and 12 postoperative months. RESULTS: Compared with one postoperative month, the RFFF volume decreased by 15.5%, 29.4%, and 42.0% at 3, 6, and 12 months, respectively, after surgery. A significant positive correlation between postoperative radiotherapy and RFFF volume changes was detected. CONCLUSION: The volume of RFFF decreases with time. It is recommended to use overcorrection, with a 40% increase in RFFF volume, to reconstruct head and neck tumor-related defects.

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.
