Reconstruction of nasal defects using modified composite grafts.

Nasal defects in certain areas such as the columellar-lobular junction, the alar rim and the soft triangle are cosmetically challenging to reconstruct. This paper describes a technique that enables the use of composite grafts for these specific nasal defects. Termed modified composite grafts (MCG), they involve creation of a dermal pedicle on the graft that enlarges the surface area of contact between the graft and the recipient bed. In addition, we used postoperative surface cooling for grafts larger than 1.5cm. Both these modifications allow reconstruction of defects larger than 1.5cm, improve graft survival and yield a better cosmetic outcome. Using representative cases from our series of 50 patients, we demonstrate that MCGs provide a simple, single-staged alternative to otherwise complex reconstruction of specific areas of the nose. They offset the need for local flaps, avoid donor-site scars and yield excellent long-term results.

Subunits of the cheek: an algorithm for the reconstruction of partial-thickness defects.

Reconstruction of partial-thickness defects of the cheek can be challenging. In addition to maintaining function, the repair must restore contour, minimise donor-site deformity and not distort the eyelid, mouth or jaw line. Since the demands for repair differ according to the site, so do the reconstructive options. To aid in selecting the best method, we classify the cheek into five subunits based on vascular anatomy and relevant landmarks. Based on our experience with 160 patients over a 12 year period, we present an algorithm that helps to select the best reconstructive option for each site. This algorithm is easy to follow and conforms to anatomical principles.

Replantation of an amputated upper lip.

Soft tissue defects of the face are a difficult reconstructive problem. Replantation of large amputated segments of the face has been rarely successful and has lagged well behind extremity trauma due in part to the relative rarity of these defects. Presented is a case of successful microvascular replantation of half of the upper lip after a dog bite.

Rupture of the radial collateral ligament of the fifth metacarpophalangeal joint.

Isolated rupture of the radial collateral ligament of the metacarpophalangeal joint of the fifth digit is a rare but disabling injury. Treatment is complicated by the influence of the hypothenar musculature, which deviates toward the ulna and flexes the digit. We have managed two cases, one chronic and one acute, by open reduction and repair. Both cases demonstrated distraction of the collateral ligament ends by the extensor sagittal band. This operative finding is not too dissimilar from the interposition of the adductor pollicis tendon between the ends of a ruptured ulnar collateral ligament in a gamekeeper's thumb injury. Because of this finding, we believe that open reduction and repair of a ruptured radial collateral ligament of the metacarpophalangeal joint of the fifth digit is indicated.

Replantation of the totally avulsed scalp.

A case report of successful microvascular replantation of a totally avulsed scalp is presented. The scalp itself, in good condition, was used as a free flap. Following operation, the right temporal artery was patent; the left was not. Repair of the left temporal artery was not attempted but large thrombi were milked from the scalp veins. Excellent perfusion of the scalp was provided through the right side. Hair growth began soon after operation, spotty at first but eventually excellent.

Cross-foot flap for ankle coverage.

The usual cross-leg flap procedures to cover composite wounds involving exposed ankle joint or bone require awkward positioning of the extremities with resultant complications. This is especially true in young, muscular patients with thick legs. A dorsalis pedis flap from the uninjured foot used as a cross-foot flap has been reliable and successful in our experience. A representative case history and the multiple advantages of this technique are described. We believe that this flap is an excellent alternative to the free-flap technique for coverage around the ankle area, especially in hospitals in which facilities for free-flap technique are not available.

Replantation of the severed ear.

A successful replantation of a completely amputated ear segment using the modified subcutaneous pocket principle has been presented. This method overcomes most of the disadvantages of other reconstructive techniques.
