A prospective case series of secondary intention healing for surgical wounds on the dorsum of the hand

Advances in Soft Tissue Injuries Associated with Open Fractures

Management of soft tissue injury is a key component in the overall treatment of upper extremity fractures. Hand surgeons must rely on their armamentarium for treating soft tissue deficits for functional outcomes. Understanding the role of fracture fixation and wound adjuncts, including negative pressure wound therapy and dermal regenerative templates, is the keys to success. In addition, detailed knowledge of local and free tissue options is essential for hand reconstruction.

Double V-Y Island Pedicle Flap for Dorsal Hand Reconstruction Following Mohs Micrographic Surgery

Medium to large defects on the dorsal hand pose a reconstructive challenge following dermatologic surgery. Repairs in this location can be complicated by a paucity of adjacent tissue reservoirs, competing tension vectors, thin cutaneous tissue, and superficial tendons and vasculature. In such cases, a double V-Y island pedicle flap is an effective reconstructive solution. It preserves hand function, harnesses local tissue with a robust blood supply, facilitates complete closure, and provides skin that closely matches the original's color and texture. Here, we present the repair of a medium to large dorsal hand defect after Mohs micrographic surgery for melanoma in situ, using a double V-Y island pedicle flap.

Second-Intention Healing in Mohs Micrographic Surgery: A Single-Center Academic Experience

OBJECTIVE

To describe the trends in second-intention healing (SIH) use at a single Mohs micrographic surgery (MMS) dermatology clinic and assess outcomes and patient satisfaction.

METHODS

The authors conducted a single-center, retrospective study of patients who underwent MMS from November 2012 through November 2018. Data obtained for each patient included sex, age, tumor characteristics, number of MMS stages, final defect size, and postoperative complications. Patient satisfaction of SIH was retrospectively assessed by telephone survey.

RESULTS

Providers used SIH in 22% of all MMS cases (n = 159/718). It was most commonly used for defects located on the nose, ear, temple, and periocular region. The average defect size and number of MMS stages for tumor clearance were 1.3 cm and 1.5 stages, respectively. Overall, low rates of postoperative complications were observed, and 95% of patients reported optimal or acceptable levels of satisfaction.

CONCLUSIONS

This study supports the idea that SIH is a safe, effective alternative for wound management and may have broader practice indications than those traditionally proposed.

Topical steroids in burn patients: A systematic review of the literature and a descriptive analysis of topical KENACOMB® use at a major tertiary burn centre

Background

Topical steroids are used widely to manage excessive inflammation and hypergranulation in burns; however, their use is controversial, and current evidence is largely anecdotal. Topical KENACOMB is a steroid preparation consisting of triamcinolone acetonide, neomycin, gramicidin, and nystatin, and it is standard of care at the Royal Brisbane and Women's Hospital burns unit. To our knowledge, there is no published literature that reports the use of KENACOMB to treat wound-associated inflammation and hypergranulation.

Objective

To synthesise current evidence surrounding the efficacy and safety of topical steroid use in treating inflammation and hypergranulation in burns patients. We also describe the use of topical KENACOMB in our burns unit.

Methods

A systematic review of PubMed, Cochrane, and EMBASE databases was performed. Articles published in English that reported the use of topical steroids for granulation tissue or inflammation in burn wounds or skin graft donor sites were included.

Results

We identified 350 articles, of which six met inclusion criteria. Four studies presented primary patient data, and two studies reported the results of surveys of burns unit professionals. A total of 54 patients were included across all studies, and no control group was reported in any study. Studies reported rapid improvements in healing, with 86.6%–100% of wounds showing complete reepithelialisation following treatment. Reported adverse outcomes included skin thinning, atrophy of granulation tissue, systemic side effects, and local wound infection.

Conclusions

This review highlights the paucity of conclusive evidence on the outcomes of topical steroids in treating inflammation and hypergranulation in burns and donor sites. While KENACOMB has shown efficacy in treating these wound types in our local experience, there is limited research available on the product. There is a clear need for quality research on the use of topical steroids in burns patients to better inform its ongoing clinical use.

Hypertrophic granulation wounds treated with silver nitrate sticks or with topical steroid: Rate of wound closure

Hypertrophic granulation (HG) is abnormal granulation tissue raised above the level of surrounding intact skin, and is thought to delay wound healing. Effective treatment to eliminate HG could speed healing, but this is not well studied. Two common treatments are chemical cautery with silver nitrate, and use of topical steroid. In a Midwestern burn and wound clinic, both of these treatments are employed. A quality improvement project compared wound size reduction for HG wounds undergoing the two treatment modalities. Retrospective chart review identified HG wounds treated during a one-year period, and compared wound size prior to and after one month of treatment (length, width and surface area). Results were presented to the clinic staff, and one year later the quality assurance project was repeated. The initial audit found data on 18 patients treated with silver nitrate cautery, and 16 patients treated with 1% hydrocortisone cream. Median length and width was decreased by 5 mm with silver nitrate cautery treatment, and by 14 mm with 1% hydrocortisone treatment (p<.05). The repeat audit one year later found 10 patients treated with silver nitrate, and 38 treated with hydrocortisone. Median length and width decreased by 0 and 2 mm respectively for silver nitrate cautery treatment, and 15 and 10 mm for 1% hydrocortisone treatment (p<.05). In conclusion, this uncontrolled review suggests faster healing in HG wounds treated with 1% hydrocortisone compared with those treated with silver nitrate cautery. Confirmation with controlled and randomized studies is warranted.

Structured zinc oxide dressing for secondary intention wounds

OBJECTIVE

Inexpensive methods for more rapid healing of secondary intention wounds are sought. This pilot study measured the wound healing rate for a new zinc oxide structured dressing technique.

METHOD

In this study, we included the three patients with the largest wounds with onset during a one month period. A 3-ply gauze was cut and placed in the centre of each wound, leaving a 3-5mm rim of the wound exposed to the zinc gauze. The central gauze was soaked with 0.9% saline solution and the entire wound area was covered with 3 layers of Unna zinc oxide dressing. The central gauze size was modified to fit as the wound healed and the size changed. The wound was photographed at each visit and wound areas were obtained using best-fit ellipses.

RESULTS

The average wound closure rate is reported in the three wounds as 21.73mm² per day. The scalp wound healed at a rate of 21.45mm² per day.; the spider bite wound healed at a rate of 28.92mm² per day; and the thigh wound healed at a rate of 14.81mm² per day.

CONCLUSION

Healing rates for the zinc gauze method exceed those previously reported for full-thickness wounds healing by secondary intention. Additional study of the new technique with more patients is needed before conclusions relevant to clinical practice can be made.
