Negative pressure wound therapy in the treatment of ulcerated infantile haemangioma.

BACKGROUND: Infantile haemangioma is a common benign tumour of infancy. Ulceration is the most common complication and is often painful and difficult to treat. Propranolol therapy is widely used to induce involution in rapidly growing or ulcerated lesions, or those in anatomically awkward locations. The ideal dressing regimen for these lesions would provide effective analgesia, act as a wound dressing, and aid involution of the primary lesion. To date, no ideal regimen has been established. Negative pressure wound therapy (NPWT) has been used in adult and paediatric populations to help improve wound healing in a variety of settings. It may provide a useful alternative to traditional dressing regimens in ulcerated infantile haemangioma. METHODS: Six consecutive patients with ulcerating infantile haemangioma presenting to the Royal Children's Hospital vascular anomalies clinic were included in the study. Each patient was treated with a combination of NPWT and propranolol. Outcomes including time to wound healing, perceived ease of dressing management, and analgesia were recorded. RESULTS: Complete wound healing was obtained in all cases. Patient outcomes in terms of analgesia, comfort, and ease of wound dressing were improved following application of NPWT. DISCUSSION/CONCLUSIONS: We propose that this regimen represents a novel therapy for management of ulcerated infantile haemangioma. Possible mechanisms for healing effect, and improved analgesia are discussed. Further investigation is required to determine if negative pressure wound therapy results in faster healing times compared to traditional dressing regimens.

Muscle versus fasciocutaneous free flaps in heel reconstruction: systematic review and meta-analysis.

BACKGROUND: Management of soft tissue injuries of the heel is challenging and the composition of free tissue transfer that provides optimal aesthetic and functional outcomes in heel reconstruction is not clear. While fasciocutaneous flaps may result in shear planes that cause instability with mobilization, insensate muscle flaps may not be able to withstand the pressures of weight bearing and thus ulcerate. METHODS: A systematic literature search was performed using Medline and PubMed databases. Primary outcome measures were time to mobilize, ulceration, revision or debulking surgery, and the requirement for specialized footwear. Analysis of pooled outcomes was undertaken using fixed-effects meta-analysis, calculating the incidence rate ratio for included articles. RESULTS: Overall 576 articles were identified; out of which 11 articles met the final inclusion criteria, detailing 168 free tissue transfers in 163 patients. The study size ranged from 4 to 72 cases. There was a trend toward higher rates of ulceration (17 vs. 26%), requirement for revision (23 vs. 31%), and the requirement for specialized footwear (35 vs. 56%) in muscle flaps, but these differences were not statistically significant. CONCLUSION: The current review provided a summary of reported outcomes of free heel reconstruction in the literature till date. With the current evidence largely limited to small cohort studies (level IV evidence), there were no significant differences found between reconstructive options. These findings serve as a call to action for more reconstructive surgeons to collaborate on multi-institutional prospective studies with robust outcomes assessment. As such, an ideal flap for reconstruction of the weight-bearing heel has not yet been made clear.

The "chimeric" trapezius muscle and fasciocutaneous flap (dorsal scapular artery perforator flap): a new design for complex 3-dimensional defects.

BACKGROUND: Multiple variations of the musculocutaneous trapezius flap have been described, each of which use a single composite musculocutaneous unit in their designs. The limitation of such designs is the ability to use the components in a 3-dimensional manner, with only 1 vector existing in the geometry of the musculocutaneous unit. METHODS: A review of the literature was undertaken with regard to designs of the musculocutaneous trapezius flap, and we present a new technique for flap design. With identification of individual perforators to each of the muscle and fasciocutaneous portions of the trapezius flap, the 2 components can act in a chimeric fashion, able to fill both a deep and complex 3-dimensional space while covering the wound with robust skin. RESULTS: A range of flap designs have been described, including transverse, oblique, and vertical skin paddles accompanying the trapezius muscle. We describe a technique with which a propeller-style skin paddle based on a cutaneous perforator can be raised in any orientation with respect to the underlying muscle. In a presented case, separation of the muscular and fasciocutaneous components of the trapezius flap was able to obliterate dead space around exposed cervicothoracic spinal metalwork and obtain robust wound closure in a patient with previous radiotherapy. CONCLUSIONS: This concomitant use of a muscle and fasciocutaneous perforator flap based on a single perforator, a so-called chimeric perforator flap, is a useful modification to trapezius musculocutaneous flap design.

Nasal Septal Flaps for Repair of Large or Recurrent Palatal Fistula: Report of Technique and 4-Year Experience.

SUMMARY: Large or multiply recurrent oronasal fistulas following cleft palate repair present a challenging problem. Nasal septal mucoperichondrial flaps have been widely used for repair of skull base defects; however, their use in the repair of oronasal cleft palate fistulas has not previously been described. In this pilot study, the authors describe anterior palatal fistula repair using a nasal septal flap and review their experience with this technique over 4 years. Fourteen patients with anterior palatal fistulas not amenable to repair using local palatal flaps were included for analysis. The mean size of the fistula was 12 mm in maximum dimension. Flap healing with complete or near-complete closure of fistula was achieved in 13 patients (93%). Five of these patients had a small, slit-like residual fistula that was asymptomatic. Nasal septal flaps are a new technique for repair of large or recurrent palatal fistulas. The procedure is well-tolerated with minimal side effects, high success rate, and low incidence of recurrence. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Cosmetic Tattooing of Free Flaps following Head and Neck Reconstruction.

Free flap reconstruction of the head and neck is a widespread procedure. The aesthetic outcome is frequently compromised by color mismatch between the donor site skin and the complex pigmentation of the face. Various surgical procedures have been described to improve the appearance of external skin paddles. Medical tattooing is commonly used for nipple pigmentation in breast reconstruction and cosmetic procedures such as permanent makeup. This article describes the technique and its application to head and neck reconstruction. Medical tattooing can be used to improve the cosmetic appearance of head and neck free flaps. There is no donor site morbidity and subtle changes in color can be replicated. The article describes the technique of medical tattooing with the use of illustrative cases. Medical tattooing is a viable alternative for improving the appearance of cutaneous skin paddles following head and neck reconstruction with free flaps. Its advantages include no donor site morbidity, availability of an infinite range of colors, no requirement for general anesthesia, and the ability to use multiple colors in the one flap for complex pigmentation requirements. Its disadvantages include the need for specialized skills and equipment and the fading of color over time.

Options for postgraduate anatomy education in Australia and New Zealand.

AIMS: Medical education in Australia has changed considerably in recent times. As a result, hours dedicated to subjects such as anatomy have been reduced. Young doctors preparing for a career in anatomy-focussed specialties such as surgery and radiology require an indepth knowledge of this subject matter. Many Australian and New Zealand universities now offer postgraduate anatomy courses to address this potential gap in a budding surgeon's education. This article summarises the current options for postgraduate surgical anatomy education in Australia and New Zealand. METHODS: All universities in Australia and New Zealand were contacted between September 2010 and December 2010 regarding the nature and content of course offerings. An Internet-based search was also conducted. RESULTS: There are currently nine universities in Australia and New Zealand offering postgraduate anatomy courses. Courses vary in contact hours, dissection time, lecture content, and examination methods. There are currently two universities offering a Postgraduate Diploma of Surgical Anatomy - the University of Melbourne, and the University of Otago. University of Western Australia and the University of New England offer a graduate diploma and a graduate certificate, respectively. Several other universities offer courses that deliver quality anatomical education but do not award students a university-recognised qualification. The Australian Orthopaedic Association now offers courses in Perth, Sydney and Brisbane, which delivers anatomy education specific to orthopaedics. CONCLUSIONS: There are a number of courses available to budding surgeons and radiologists to help fill the anatomy education void. With the development of such courses questions of accessibility, affordability and equity remain.
