BACKGROUND: The shortage of tissue for large defect reconstruction is a challenge for the plastic surgeon. Tissue expansion emerged in this context, and in the last 30 years has become one of the most widely used modalities in reconstructive surgery. Tissue expansion is a very versatile technique that can be performed in patients of all ages for the correction of different pathologies. The most common indications are burn sequelae and giant congenital nevus. The present study describes the indications and use of tissue expanders at the Hospital de Clínicas of Universidade Federal do Paraná. METHODS: Patients who underwent tissue expansion for reconstructive surgery between January 2005 and December 2009 were retrospectively reviewed. RESULTS: A total of 24 patients (70.8% female and 29.2% male) were analyzed. Ages ranged from 3 to 46 years old (average, 17.1 years). The most common indication for tissue expansion was the treatment of burn sequelae (62.5%), mainly in the head and neck. Alopecia was the second most prevalent indication (29.2%), followed by scar retraction in the neck (20.8%). Other indications were giant congenital melanocytic nevus (16.7%), Poland's syndrome (8.3%), abdominal scar (8.3%), and amastia (4.2%). Complications developed in 11 patients, and the highest incidence of complications, reported in 8 (72.7%) patients, was among those with burn sequelae as the primary pathology. The complications were infection, rupture, extrusion, wound dehiscence, and displacement of the expander. CONCLUSIONS: Tissue expansion is indicated for the treatment of several diseases among which burn sequelae is one of the most common indications.
