About this trial

This is an interventional treatment trial for Scar focused on measuring scar, contracture, perforator flap, preexpanded perforator flap, perforator vessel, artery diameter

Eligibility Criteria

6 Years - 60 Years (Child, Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • patients with broad scars and contracture bands
  • patients with esophagocutaneous fistula
  • patients with ambiguous genitalia

Exclusion Criteria:

  • none

    control side

    Arm Description

    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.

    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.

    Outcomes

    Primary Outcome Measures

    Transferred tissue dimensions
    Demonstrating the amount of transferred healthy tissue exhibits the success of the technique.

    Secondary Outcome Measures

    Diameter of the perforator artery in a particular tissue level
    This measurement will reveal one of the morphologic changes happen during tissue expansion period (perforator flap preexpansion). This measurement will be done for the last six patients. The diameter of the perforator artery of the preexpanded flap will be compared with both the diameter of the same artery before the expansion process and the diameter of the equivalent perforator artery of the symmetric side (non expanded side)of the body.

    5. Study Description

    Brief Summary
    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.
