Microvascular free-tissue transfer in children.

We have reviewed our experience with 22 microvascular free-tissue transfers in children. Ages range from 2 to 14 years; the success rate was 96 percent. Two patients underwent reexploration for postoperative hemorrhage, possibly due to treatment with low-molecular-weight dextran. No vessel spasm was observed, compared with a 28 percent incidence in our adult series of 154 patients. The vessels were in pristine condition. Operative time was shorter (6.1 hours) than in our adult series (9.7 hours). Average hospital stay was 10 days (compared to 23 days for adults). All children have resumed almost normal activity within 2 months (4 months for adults). Results of this study indicate that microvascular free-tissue transfer can be accomplished safely and expeditiously in children. Care should be taken in preoperative and postoperative planning, however, especially concerning immobilization.

A multidisciplinary approach to orbital neoplasm.

The patient with orbital and periorbital neoplasia requires careful assessment of the extent and biologic activity as well as histopathologic categorization. Treatment is optimal through a multidisciplinary approach involving the ophthalmic surgeon, plastic surgeon, neurosurgeon, head and neck surgeon, and oral surgeon.

The technique of cranial bone grafts in the correction of posttraumatic orbital deformities.

The technique of split-thickness cranial bone graft for reconstructive orbital surgery, is reported in five patients who sustained extensive orbital trauma. This technique involves exposing the skull via a coronal scalp incision, after which the cranial bone is split in situ along the diploe. The outer table of the cranial bone is then used as a graft to correct orbital defects and other associated bony deformities. Cranial bone grafts have several advantages over other graft sites in orbital reconstruction, including more rapid postoperative recovery, close proximity of donor site to recipient site, and improved survival of cranial bone grafts in experimental studies. Cranial bone grafts are an important source of autogenous tissue for the reconstructive surgeon.

Thumb reconstruction in the burned hand by advancement pollicization of the second ray remnant.

Reconstruction of 15 thumbs in 14 patients with severe postburn deformity has been carried out by advancement and transferral of the second ray remnant onto the remaining proximal thumb metacarpal stump. This technique combines the advantages of thumb lengthening and pollicization procedures in a single operation and has been a useful method for restoration of single hand prehension in the severely burned mitten hand.

Digital replantation distal to the proximal interphalangeal joint.

Microvascular replantation of digits distal to the proximal interphalangeal joint were reviewed in 24 digits in 18 patients. Of the 24 digits studied, five were seen in patients who had a single digit amputated and replanted, 10 were seen in patients who had multiple distal digital amputations and replantations, and eight were seen in patients who had other proximal digital replantations or other associated hand injuries in addition to the distal replantations. Survival rate in this study was 96%, and the mean active range of motion at the proximal interphalangeal joint was 95 degrees with 8.9 degrees active motion at the distal interphalangeal joint. Two-point discrimination averaged 11 mm, and all patients had some cold intolerance. The nine students in this study required a mean 1.7 months to return to school; nine patients were workers and required a mean of 5.1 months to return to work. Acceptance for the procedures was overwhelmingly good. Replantation of an amputated digit distal to the proximal interphalangeal joint in selected cases can be a worthwhile procedure.

Teres major--latissimus dorsi skin-muscle flap for chest-wall reconstruction.

The complete survival of a teres major--latissimus dorsi skin-muscle flap for chest reconstruction is reported in a patient in whom the primary neurovascular pedicle of the latissimus muscle had previously been sacrificed. At operation, collateral vessels of 1-mm proportions were noted to have developed between the innervated teres major and denervated latissimus dorsi muscle. In this case, the teres major muscle rotated with the latissimus muscle to affect reconstruction of a full-thickness anterior chest resection. This report suggests the possibility of a denervated, relatively devascularized muscle obtaining additional blood supply from adjacent innervated vascularized muscles and supports the concept of rotating the muscles as a unit to encourage viability of the denervated component.
