Abstract:
Objective:To explore the subunit strategy for perineal defect reconstruction and flap selection.
Methods:This is a respective study of 21 patients, with perineal defect, during January 2008 to December 2018. All patients were admitted to the fifth section of Burn and Plastic Surgery in the Fourth Medical Center of the People′s Liberation Army General Hospital. There were 10 males and 11 females, aged from 4 to 68 years old, with the mean age of 26.4 years. The causes of injury included burn (n=11), trauma (n=2), Paget′s disease (n=2), Brown′s disease (n=2), perineal squamous cell carcinoma (n=3)and hemangioma (n=1). The perineum is divided into 4 subunits, according to the anatomical structure: a front area monsveneris or pubic symphysis, 2 middle areas (labia or scrotum) and a posterior area (anal). The defects ranged 23 cm×11 cm-5 cm×3 cm after perineal lesions were removed. Appropriate flaps were selected based on tissue defect.
Results:Nine patients were repaired with superficial inferior epigastric artery flap, 3 patients were repaired with superficial circumflex iliac artery flap, and 2 patients were repaired with combined superficial inferior epigastric artery flap and superficial circumflex iliac artery island flap. Internal pudendal arterial perforator flap was performed in 5 patients, and anterolateral thigh perforator flap in 2 patients. The size of flap was 25 cm×12 cm-6 cm×3 cm. All flaps survived, and incisions were primary healing. Patients were followed up for 6 months to 9 years, with an average of 13 months. The patients were satisfied with the appearances and functions of the recipient and doner sites. Scars were concealed well.
Conclusions:Appropriate flap can be chosen to repair perineal defects, based on the subunit principle in perineum, in order to restore function and appearance, and achieve satisfactory clinical outcomes.
