use to remove strong odours but does not specifically mention chlorhexidine, however Lucht et al.2 suggest dipping leeches in a chlorhexidine solution before application to reduce infection rates. It has left us wondering that we may suspect leech therapy is of no further benefit, where in fact they just do not like chlorhexidine. We would be interested to hear if any other units have made a similar observation.

extremity was fitted with a compression bandage and a brace to ensure complete immobilisation. The donor site was inspected daily and noted to be clean and dry, but on day 16 a slightly necrotic area with a dark eschar was noted in the skin graft, which was debrided immediately. There was a deep area of necrotic tissue with invasion of the underlying peroneus longus and soleus muscles. From then on, the surgical wound was debrided daily and had improved considerably by the third day (Fig. 1). The wound healed well and was covered with a skin graft at 2 weeks. Microscopic examination of the excised fasciomuscular tissue showed non-septate, irregular hyphae, and vascular invasion consistent with mucormycosis. Unfortunately, our patient was unable to lift her toes and extend her foot because of a palsy of the left peroneal nerve, of which electromyography at 6 months showed reduced stimulation. Despite physiotherapy she now has severe dysfunction of the leg that requires walking aids and severely restricts her activities of daily living. To our knowledge this is the first report of postoperative peroneal neuropathy as a complication of mucormycosis of the donor site after harvest of a fibular flap. Mucormycosis of the skin and wounds has been associated with burns, traumatic disruption of skin, persistent maceration of the skin, and use of contaminated elastic bandages.2 It can be locally invasive and penetrate from the cutaneous and subcutaneous tissues into the adjacent fat, muscle, fascia, and even bone. However, isolated mucormycosis has a favourable prognosis and a low mortality if the wound is debrided extensively and necrotic and infected tissues are resected promptly.3 In our

Postoperative donor-site mucormycosis after fibula flap harvest Sir, We read with interest the paper by Sieg et al.1 and present an unusual case from our own experience. A 45-year-old woman had a secondary reconstruction with a left fibular free flap for restoration of a mandibular defect after resection of an oral carcinoma. She had no coexisting medical conditions such as type II diabetes. We dissected a fibular osteofasciocutaneous flap by the usual technique including 8 cm of bone and a skin paddle about 12 cm long. A tourniquet was used. The skin of the donor site was closed with a partial skin graft taken from the thigh. The donor

case, necrosis of deep fascia and muscle by fungal infection and aggressive debridement of the wound were the main risk factors of long-term morbidity at the donor site.

One dog bite too far Sir, Dog bites account for 250,000 minor injury and emergency unit attendances in the UK each year. These are located on the face in over 77% of cases with the predominant areas affected being the nose, cheeks and the ear.1,2 Thus, when the patient seeks medical attention, Maxillofacial surgeons are frequently involved in their management. We have noticed an increasing number of patients presenting with facial dogbite wounds, bitten on more than one occasion. In the last year we had two patients that sustained facial wounds from their same dog twice. These have commonly involved the family pet (Fig. 1). As a specialty we are uniquely positioned

to promote prevention strategies and patient education. This role in prevention and education could be in conjunction with our Veterinary Colleagues, and would increase the profile of our specialty to the general public. We feel any opportunity to raise awareness and educate towards prevention of facial dogbite wounds and the associated facial disfigurement should be encouraged by our specialty.
