Running Vertical Mattress Suture Technique

IntroductionBased on the principles of the ideal skin closure technique, we previously described a suture technique (wedge-shaped excision and modified buried vertical mattress suture (WE-MBVMS)) that could provide excellent outcomes for the most demanding surfaces. However, adequate clinical comparative evidence supporting improved outcomes is lacking. Thus, the purpose of this protocol is to establish the feasibility of conducting a fully randomised controlled trial (RCT) comparing the clinical effectiveness of WE-MBVMS with a buried intradermal suture (BIS) in closing thoracic incision.Methods and analysisThis study is a feasibility RCT of WE-MBVMS and BIS in patients undergoing surgery for costal cartilage harvesting. Seventy-eight participants are expected to participate in the study and will be randomised in a ratio of 1:1 to WE-MBVMS or BIS. Trial feasibility will be assessed by the number of participants assessed for eligibility, recruitment rates, reasons for ineligibility or non-participation, time for interventions, withdrawal and retention at all follow-up points (3, 6 and 12 months), follow-up rates and reasons for withdrawing from the trial. In addition, clinical data regarding the cosmetic results of scars will be collected to inform the sample size for a fully powered RCT.Ethics and disseminationThis study has been approved by The First Affiliated Hospital of Xi’an Jiaotong University Institutional Review Board (XJTU1AF2017LSK-120). The findings will be published in peer-reviewed journals.Trial registration numberChiCTR-INR-17013335; Pre-results.

Guide tissue regeneration (GTR) is the treatment of infrabony pockets for soft and hard tissue regeneration. Membrane is used as a barrier and prevents apical migration of the cells in epithelial tissues. Membrane fixation is one of the procedures in GTR treatment because resorbed membrane is less stable. Simple sling suture technique for membrane fixation has 1 anchorage, located in coronal flap, while periosteal vertical mattress suture technique has 2 anchorages in periosteum, making it more stable. This study aimed to study the differences in the effectiveness of membrane fixation using periosteal vertical mattress suture and simple sling suture techniques in terms of probing depth, relative attachment loss, and alveolar bone height in the treatment of infrabony pockets. The samples were divided into 2 groups. The first group was open flap debridement (OFD) with demineralized freeze dried bone allograft (DFDBA) application and membrane fixation with simple sling suture, while the second group was OFD with DFDBA application and membrane fixation with periosteal vertical mattress suture, observed on day 0, 30th day, and 90th day. The results of the study showed significant differences in the probing depth and relative attachment loss (except from the 30th day to the 90th day), and there were no significant differences in the alveolar bone height from the baseline to the 90th day, between the group of membrane fixation using simple sling suture and that of periosteal vertical mattress suture techniques on flap surgery. This study concluded that membrane fixation in the treatment of infrabony pocket with periosteal vertical mattress suture technique is more effective in reducing the probing depth and relative attachment loss, but there is no difference in increasing the alveolar bone height when compared to simple sling suture technique.
