The Speedo Tie-Over Dressing

Extra-wound fixation: a modified tie-over dressing technique for skin graft

OBJECTIVE

Tie-over dressing is the most frequently used technique of skin grafting. However, many deficiencies affecting the outcome have been reported. We hereby introduce a modified method, termed the 'extra-wound fixation technique', for skin dressing, and evaluate the complications and clinical outcomes.

METHOD

In this retrospective cross-sectional study we analysed the medical records of patients treated between January 2012 and December 2017. All patients received full thickness skin grafts. Patients were divided equally into to groups: patients were treated using the extra-wound fixation technique, and the remaining, randomly selected patients treated using the traditional tie-over method. The extra-wound fixation technique uses the traditional tie-over dressing method followed by additional stitches made in healthy skin locating 0.5-1.0 cm laterally to the wound edge. The follow-up outcomes between the two groups were compared using the Chi-square test.

RESULTS

A total of 38 patients took part (19 patients in each group). The follow-up duration was 1-6 months. No raised edges were observed in any of the patients. Prolonged follow-up demonstrated that the grafted skin texture became soft with a thin layer of adipose tissue, and elasticity was gradually improved along with the regeneration of dermoelastic fibre. The colour was similar to the normal skin with a smooth surface. Compared with the traditional method, the extra-wound fixation technique significantly improved the survival of the grafted skin (p=0.008), reduced the risk of laceration of the skin (p=0.001), and eliminated crater rim-like appearances (p=0.020).

CONCLUSION

The extra-wound fixation technique could be used for different skin grafts and improve clinical outcomes compared with the traditional tie-over dressing method.

Full-thickness Skin Graft Fixation Techniques: A Review of the Literature

Multiple techniques for skin graft fixation have been proposed, but the evidence underlying these techniques is unclear. This study aimed to review the literature for full-thickness graft fixation techniques. PubMed was electronically searched to identify relevant studies. The search strategy identified 91 relevant articles. These consisted of 2 randomised controlled trials (RCTs), 10 observational cohort studies (8 retrospective, 2 prospective), and 79 descriptive studies (case series, case reports, or expert opinion articles). Both identified RCTs compared the tie-over dressing against a modified tie-over dressing. The tie-over dressing was also included in all identified observational studies, and comparisons were made against quilting/mattress suturing (4 studies, 181 grafts in total), simple pressure dressings (3 studies, 528 grafts), non-tie-over dressings non-specifically (1 study, 71 grafts), hydrocolloid dressings (1 study, 62 grafts), and double-tie over dressings (1 study, 43 grafts). No significant differences were found between fixation methods for graft take, haematoma rate, and infection rate. No studies have found a significant difference between tie-over dressings and alternative graft fixation technique, with the most evidence for simple pressure dressings and quilting/mattress suturing. However, the evidence base consists mostly of small, retrospective observational studies. This article describes the current evidence base and this should be considered when planning future reports in the field.

Tie-Over Bolster Dressings vs Basting Sutures for the Closure of Full-Thickness Skin Grafts: A Review of the Literature

BACKGROUND

Full-thickness skin grafting is a well-established technique in the reconstruction of various tissue defects and wounds. However, lack of uniformity in the procedure of closing and securing the grafts has led to a wide range of different techniques.

OBJECTIVE

This article reviews the use of tie-over bolster dressings compared to basting sutures for the fixation and postsurgical immobilization of full-thickness skin grafts (FTSGs), discusses details of each method, and proposes a practice guideline for the closure of FTSGs.

METHODS

A traditional review of the literature was performed through a search of PubMed using the following keywords: full-thickness skin graft, FTSG, closure, suture, tie-over bolster, quilting, and bolster.

RESULTS

The current literature regarding tie-over bolster dressings does not demonstrate improved outcomes compared to quilting sutures. The 2 techniques appear equivalent in terms of utility and outcome, both possessing distinct advantages and disadvantages.

CONCLUSION

Despite minimal head-to-head studies between tie-over bolsters and quilting, the best evidence from the literature appears to show comparable results regarding graft take, cosmetic outcomes, and postoperative complications. Ultimately, the choice of using a tie-over bolster technique or quilting sutures relies on surgeon preference and anatomic location.
