Background: Tissue expansion is a common reconstructive surgery especially in burned patients. This study has been designed to evaluate the rate of complications of this method in Hazrat Fatima Hospital between 1389-1391.

Materials & Methods: In this cross sectional and retrospective study, 150 patients' records have been studied between 1389-1391 years, frequency rate and types of complications related to tissue expander have been surveyed in these patients.

Results: Complications have been observed in about 7% of the patients included in this study. Exposure of tissue expander was the most common complication (81.8%). Other complications which are resulted from this issue are capsular contracture and infection. Age was the only factor which had significant relation with increasing complication among the other surveyed factors including age, sex, indication of operation, wound location and duration of anaesthesia.(p=0.033)

Conclusion: The incidence of complication in patients that required tissue expander was not high and it was less than 10%. It should be noted that patient selection should be carefully in paediatric group and also strict observance of surgical principles is necessary to avoid complication.
