Repair of maxillofacial soft tissue defect with superficial abdominal artery flap assisted by color doppler ultrasound / 中华整形外科杂志

ABSTRACT

Objective@#To investigate the clinical effect of free lower abdominal perforator flaps assisted by color Doppler ultrasound in repairing oral maxillofacial soft tissue defects.@*Methods@#From June 2018 to March 2019, five patients with oral cancer underwent surgical treatment. There were 2 males and 3 females, age from 45-69 years old. At the same time, free lower abdominal flaps pedicled with superficial circumflex iliac artery or superficial inferior epigastric artery were used to repair oral maxillofacial soft tissue defects under preoperative color Doppler ultrasound evaluation and localization.@*Results@#All the five cases survived. Three cases were repaired with superficial inferior epigastric artery flap and two cases were repaired with superficial circumflex iliac artery flaps. These flaps ranged from 5 cm ×6 cm to 7 cm×9 cm. The follow-up period ranged from 3 to 12 months, with an average of 6 months. The flaps were soft, without obvious swelling, hairless growth, scarless contracture and limited mouth opening. All donor and recipient areas were healed in one stage.@*Conclusions@#The lower abdominal perforator flaps assisted by color Doppler ultrasound for repairing oral and maxillofacial soft tissue defects are characterized by accurate selection and localization of blood vessels, convenient extraction of skin flaps and minimal morbidity of donor site. It is a good method for repairing oral and maxillofacial soft tissue defects.
