Clinical outcomes following surgical treatment of lentigo maligna of the head and neck.

INTRODUCTION: Lentigo maligna (LM), a subtype of melanoma in-situ commonly occurring in the head and neck region, often presents a treatment challenge due to anatomical constraints, particularly on the face of mostly elderly patients. This study sought to assess the clinical outcomes of wide local excision of head and neck LM, identify predictors of recurrence and define optimal excision margins. MATERIALS AND METHODS: Patients with LM treated between January 1997 and December 2012 were identified from the large institutional database of a tertiary center and their data were analyzed. RESULTS: In 379 patients, 382 lesions were eligible for analysis. Median maximal lesion diameter was 10.5 mm. The mean surgical excision and histopathological clearance margins were 6.2 mm and 4.0 mm, respectively. Median follow-up was 32 months. The LM recurrence rate was 9.9%, and subsequent invasive melanoma developed in 2.3% of cases (mean Breslow thickness 0.7 mm). The recurrence rate was 27.2% if the histological margin was <3.0 mm (median time to recurrence 46.5 months) compared with 2.6% if the margin was ≥3.0 mm. The mean surgical margin required to achieve a histological clearance of ≥3.0 mm was 6.5 mm. CONCLUSIONS: Our data suggest that to minimize recurrence, a histological margin of ≥3.0 mm is required. To achieve this, a surgical margin of ≥6.5 mm was required. This is greater than the 5 mm margin recommended in some national guidelines. Careful long-term follow-up is required for all patients because of the risk of recurrence.

Propranolol for Surgeons in the Treatment of Infantile Hemangiomas.

INTRODUCTION: Beta-blocker (Propanolol or Timolol maleate) treatment of infantile hemangiomas (IH) is a safe and effective treatment in the outpatient setting. The authors report a single surgeon's initial experience with setting up an outpatient service of beta-blocker treatment for head and neck IH at a tertiary children's hospital. METHODS: A prospective study of children with head and neck IHs commenced in January 2015 with the end point being December 2018. Each child started either oral propranolol (2 mg/kg/day) or topical Timolol 0.5%. RESULTS: Thirty-eight patients commenced a beta-blocker during the study duration. The mean age at time of starting therapy was 9 months (range 3 weeks to 116 months). Four patients were older than 12 months at commencement. The mean duration of treatment was 9 months. The response to treatment was excellent or complete in 29% (n = 11), good in 50% (n = 18) and mild in 10% (n = 4). The non response rate was 10% (n = 4). No major adverse effects occurred but 29% (n = 11) experienced minor side effects. CONCLUSION: Low dose propranolol and topical Timolol is been safe and easy to use for surgeons who may not be regular prescribers or unfamiliar with treating children with IHs with beta-blocker therapy. In patient monitoring is unnecessary and parents can be taught easily to recognise side effects. Treating children from the start builds a trusting relationship with the family before the child requesting cosmetic revision of the fibro-fatty remnant.

Are overweight and obese patients who receive autologous free-flap breast reconstruction satisfied with their postoperative outcome? A single-centre study.

INTRODUCTION: Obese and overweight patients represent a challenging surgical group for autologous free-flap breast reconstruction. There is a paucity of information regarding post-operative patient-reported satisfaction in this increasingly prevalent cohort. This retrospective study aimed to determine using BREAST-Q patient-reported satisfaction amongst normal, overweight and obese patients receiving autologous free-flap breast reconstruction. METHODS: BREAST-Q (post-reconstruction) module was sent to 174 autologous breast free flap reconstruction patients between 2001 and 2012. Clinical data were collated for patients who returned questionnaires. Post-operative complications and satisfaction scores were compared between normal versus overweight and obese patients. RESULTS: A total of 101 patients (normal body mass index (BMI) = 27; overweight BMI = 48 and obese BMI = 25) completed BREAST-Q (response rate 66%). Obese and overweight patients are significantly more likely to develop major (44.8% and 31.1% vs. 29.6%) and minor (34.4% and 20% vs. 7.4%) complications in comparison to normal BMI patients (p < 0.02). Overweight and obese patients demonstrated similar levels of satisfaction compared with normal patients with the shape of their reconstructed breasts (73.2 and 72.1 vs. 71.2; p > 0.05) and overall surgical outcome (75.8 and 78.9 vs. 75.4; p > 0.05). CONCLUSIONS: Patient post-operative satisfaction is gaining increasing relevance in assessing the outcomes from autologous breast reconstruction. Overweight and obese women benefit from autologous breast reconstruction, despite being at increased risk of post-operative complications, and eventually achieve comparable levels of post-operative satisfaction. This should be reflected in pre-operative counselling.

Funding analysis of bilateral autologous free-flap breast reconstructions in Australia.

INTRODUCTION: Bilateral breast reconstructions are being increasingly performed. Autologous free-flap reconstructions represent the gold standard for post-mastectomy breast reconstruction but are resource intensive. This study aims to investigate the difference between hospital reimbursement and true cost of bilateral autologous free-flap reconstructions. METHODS: Retrospective analysis of patients who underwent bilateral autologous free-flap reconstructions at a single Australian tertiary referral centre was performed. Hospital reimbursement was determined from coding analysis. A true cost analysis was also performed. Comparisons were made considering the effect of timing, indication and complications of the procedure. RESULTS: Forty-six bilateral autologous free-flap procedures were performed (87 deep inferior epigastric perforators (DIEPs), four superficial inferior epigastric artery perforator flaps (SIEAs) and one muscle-sparing free transverse rectus abdominis myocutaneous flap (MS-TRAM)). The mean funding discrepancy between hospital reimbursement and actual cost was $12,137 ± $8539 (mean ± standard deviation (SD)) (n = 46). Twenty-four per cent (n = 11) of the cases had been coded inaccurately. If these cases were excluded from analysis, the mean funding discrepancy per case was $9168 ± $7453 (n = 35). Minor and major complications significantly increased the true cost and funding discrepancy (p = 0.02). CONCLUSION: Bilateral free-flap breast reconstructions performed in Australian public hospitals result in a funding discrepancy. Failure to be economically viable threatens the provision of this procedure in the public system. Plastic surgeons and hospital managers need to adopt measures in order to make these gold-standard procedures cost neutral.

The largest reported epineural ganglion of the ulnar nerve causing cubital tunnel syndrome: case report and review of the literature.

We describe the largest reported epineural ganglion of the ulnar nerve arising in the cubital tunnel. A 54-year-old male, driver presented with progressive symptoms of left sided cubital tunnel syndrome. Surgery demonstrated a 11 × 3 cm ganglion which was successfully removed. Post-operatively the patient demonstrated partial recovery with no recurrence of the ganglion.

Preparation of an adipogenic hydrogel from subcutaneous adipose tissue.

The ability to generate controlled amounts of adipose tissue would greatly ease the burden on hospitals for reconstructive surgery. We have previously shown that a tissue engineering chamber containing a vascular pedicle was capable of forming new fat; however, further refinements are required to enhance fat formation. The development and maintenance of engineered adipose tissue requires a suitable source of growth factors and a suitable scaffold. A hydrogel derived from adipose tissue may fulfil this need. Subcutaneous fat was processed into a thermosensitive hydrogel we refer to as adipose-derived matrix (ADM). Protein analysis revealed high levels of basement membrane proteins, collagens and detectable levels of growth factors. Adipose-derived stem cells exposed to this hydrogel differentiated into adipocytes with >90% efficiency and in vivo testing in rats showed significant signs of adipogenesis after 8 weeks. ADM's adipogenic properties combined with its simple gelation, relatively long shelf life and its tolerance to multiple freeze-thaw cycles, makes it a promising candidate for adipose engineering applications.
