          ABSTRACT

          Failed hypospadiass cases may result in hypovascular, scarred penis with residual penile chordee and leave the patient with minimal residual skin for penile resurfacing and urethroplasty. Local tissue expansion has become a good alternative to provide skin for penis by using expanders however they require long periods of time for expansion. Besides, rapid tissue expansion was also described in different tissues. We used rapid intraoperative expansion technique by using a Foley catheter in a failed hypospadias case who had minimal residual skin secondary to infection and we concluded that rapid intraoperative tissue expansion with Foley catheter is an effective, feasible reconstructive method for easy dissection and penile resurfacing in failed hypospadiass cases.

          Risk factors for complications in pediatric tissue expansion.

          Tissue expansion in children has been associated with complication rates of 20 to 40 percent. A critical analysis of 6 years' (1988-1993) experience with 180 expanders placed in 82 consecutive children was performed to identify those factors which predispose to complications. Major and minor complications each occurred in 9 percent of patients. The factors associated with a statistically significant increase in complications were burns and soft-tissue loss, patient age under 7 years, use of internal expander ports, and a history of two or more prior expansions. In addition, complications were significantly more likely to occur within the first 90 days than during any subsequent expansion. Factors that did not influence complication rate included patient gender, wound drainage upon expander insertion or removal, intraoperative use of antibiotic irrigation, number of expanders placed, use of customized expanders, and operating surgeon.

            Treatment of a congenital melanocytic nevus on the forehead with immediate tissue expansion technique: a three-year follow-up.

            The aim of this case report was to determine the method and basic principles of immediate tissue expansion using a Foley catheter in the forehead region for treating a medium-sized congenital melanocytic nevus. A 4-year-old child presented with a supraorbitally located forehead congenital melanocytic nevus, close to the midline. Total excision and reconstruction with intraoperatively expanded forehead skin below the hairline was performed. Intraoperative tissue expansion using a Foley catheter allowed us to obtain expanded and enhanced local tissue, which had tissue characteristics similar to those of the forehead skin, and thus closure of a medium-sized defect without distorting important anatomic structures such as the brow and frontal hairline was possible. Of the two methods of tissue expansion, immediate expansion using a Foley catheter is a good alternative in single-stage reconstruction of head and neck defects because it has the advantage of omnidirectional expansion.

              Rapid intraoperative tissue expansion in reconstruction of the head and neck.

              A prolonged tissue expansion has the advantage of creating large amounts of additional skin for reconstructing cutaneous defects that might not be possible without the use of multiple, regional, distant, or microsurgical flaps. In spite of this, there are disadvantages, many of which can be circumvented by the use of rapid intraoperative tissue expansion instead. Although rapid expansion does not increase skin surface area as much as prolonged expansion, it may be helpful in assisting with closure of defects that might otherwise be problematic.
