简要总结
Tissue expansion methods have been recommended as a means of improving the clinical results with perforator flaps but in plastic surgery literature there are few clinical trials supporting this opinion. The purposes of this clinical study are to address the ''preexpanded perforator flap concept'' by demonstrating a case series of relevant reconstructive procedures and to evaluate the perforator vessel changes that happen during the expansion periods of various perforator flap donor sites.

研究组 & 干预措施
preexpanded flap
Fourteen patients were treated with fifteen '' preexpanded perforator flap surgery '' interventions. The last six cases were evaluated in terms of perforator artery diameter before and after expansion process. The preexpanded flap donor sites' perforator artery diameters were also compared with their anatomic equivalents located in the symmetric side of the body.
干预措施: preexpanded perforator flap surgery (Procedure)
control side
In six of the 14 patients, perforator artery diameter of the nonexpanded symmetric anatomical side of the body (equivalent to the expanded site)were measured.
结局指标
主要结局
Transferred tissue dimensions
时间窗: At least five months after the operation
Demonstrating the amount of transferred healthy tissue exhibits the success of the technique.
次要结局
- Diameter of the perforator artery in a particular tissue level(Measured the day before the expander implantation surgery and the day before the flap transfer surgery (second session following tissue expansion))
