Correction of thumb deformities after burn: versatility of first dorsal metacarpal artery flap.

In the management of a debilitated burned hand due to contractures, thumb reconstruction constitutes the most crucial part for a beneficial functional outcome. Among the limited local flap alternatives for the thumb, the first dorsal metacarpal artery flap, harvested from the dorsal aspect of the index finger can provide elastic, durable and sensate coverage for soft tissue defects after contracture release. In a 3-year period, neurovascular island first dorsal metacarpal artery flap was used in 14 patients suffering thumb deformities. The time elapsed after the underlying injury until reconstruction ranged from 5 months to 17 years. Follow-up revealed that all deformities were successfully treated with satisfactory functional recovery and cosmetic results. Donor site morbidity was minimal with an acceptable scar on the dorsum of the index finger and adequate tendon gliding without producing extension deficit. Our experience with management of deformities involving the thumb and/or adjacent thenar area revealed that the first dorsal metacarpal artery flap is a reliable local neurovascular island flap option, offering acceptable functional and cosmetic outcomes in respect to sensation, elasticity, durability and skin-match.

Congenital double lip: review of 5 cases.

Congenital double lip is rare and usually involves the upper lip. Apart from a deformity that interferes with speech and mastication, operation may be indicated for cosmetic reasons. We have operated on five patients with double lip deformities for cosmetic reasons. Although a midline constriction band between two mucosal bulges is thought to be a constant feature, four of our five cases did not have a midline constriction. We used an elliptical excision of the mucosal excess in the four patients. The one with central constriction had an elliptical excision on each side, combined with a vertical midline Z-plasty to release the central constriction. Satisfactory aesthetic results were achieved in all patients.

Versatility of the reverse lateral arm flap in the treatment of post-burn antecubital contractures.

If they are not managed with proper treatment and rehabilitation, full thickness burns involving the cubital fossa may result in severe contractures that may impair upper extremity functions. Later release of these contractures discloses a large soft tissue defect that should be replaced. We used reverse lateral arm flaps for coverage of the cubital fossa in 11 selected cases of antecubital contracture. Ten flaps survived totally while we experienced one distal partial necrosis, which was later treated by skin grafting. We achieved considerable functional improvements in all cases. Although fasciocutaneous flaps offer the advantage of using regional tissue in a single stage, few versatile local flaps relying on the vascular anatomy around the elbow joint are available for cubital fossa coverage. Being a rapid, easy and one-staged procedure with no necessities for sacrifice of a major artery or muscle and for a long-term immobilization of the involved joints, reverse lateral arm flaps appears to be advantageous in comparison to other options for coverage of the cubital fossa defects after the release of antecubital contractures.

A custom-made distraction device for experimental mandibular distraction osteogenesis.

Distraction osteogenesis has recently become popular in craniofacial reconstruction, after it was first described for long bones. Despite the widespread clinical use of this technique, currently, lack of an ideal experimental model for small animals hampers investigations focused on its molecular basis, which warrants further elucidation. The authors developed a new device for distraction of the rat mandible and, to asses its effectiveness, practiced on 30 animals assigned to either an acute 3-mm distraction group (n = 7) or a gradual distraction group (0.25 mm twice a day for 6 days; n = 23). The authors applied the devices to a localization that allowed them to perform the ostomies posterior to the molar teeth. Because of a U-shaped plate that the authors used for posterior pin fixation, their device maintained its stability until the end of the study, despite the delicate anatomy of the bone at the posterior part of the mandible. Additionally, the authors described a practical and easy method of transient mandibular stabilization method that facilitates the manipulations while the mouth is open for safer airway control during surgery. This new nutrition technique with enteral feeding solution solved the problem of progressive weight loss after surgery. Application of the device was easy and practical, without demanding complex manipulations. The authors did not observe any device dislodgement or a high rate of accidental fractures during the manipulations. They demonstrated that the device works properly and is able to create ossified regenerate bones that fill the entire distraction gap, which can be used for various investigations during distraction osteogenesis.

An unusual burn injury caused by a car battery.

In a car battery accident, a 21-year old man sustained a band of deep burn involving the dorsoradial aspect of the wrist. He was treated by excision and grafting on the third day after injury. A metal watchstrap that the patient was wearing, with evidence of the arching phenomenon on it, short-circuited the battery of the vehicle. Although the underlying etiology that triggered the events leading to thermal injury was an electrical accident, the current did not pass through any part of the patient's body, as what happens in an electrical injury. In our current understanding, the pathophysiology of electrical injury dictates the transmission of current through living tissues, leading to a specific type of tissue damage that should be distinguishable from the type that results from a usual thermal injury, as it happened in our case.
