Effect of axial flap of adjacent artery perforator with vascular pedicle in repairing facial and cervical scar deformity in patients / 中华烧伤杂志

ABSTRACT

Objective@#To explore the effect of axial flap of adjacent artery perforator with vascular pedicle in repairing scar deformity of face and neck in patients.@*Methods@#From January 2010 to June 2018, 38 patients with cicatricial deformity of face and neck after deep burn were admitted to author′s unit, including 22 males and 16 females, aged 5-56 years. The time of admission was 7 months to 19 years after burn injury. The size of wounds ranged from 7.0 cm×4.0 cm to 20.0 cm×10.0 cm after scar tissue was released. Nineteen patients were treated by upper thoracic internal artery perforator flap with size ranged from 7.0 cm×5.0 cm to 18.0 cm×8.5 cm. Among them, 16 cases were preexpanded with expanders at thorax whose rated capacity ranged from 300 to 500 mL and times of water injection of 1.8 to 3.1, and 3 cases were directly used. Twelve patients were treated by transverse carotid artery perforator flap with size ranging from 7.0 cm×4.5 cm to 11.0 cm×8.5 cm, of which 8 patients were preexpanded and 4 cases were directly used. The rated capacity of expander placed at the supraclavicular region ranged from 200 to 350 mL with times of water injection from 1.5 to 2.0. Seven patients were treated by preexpanded superficial temporal frontal branch artery perforator flap with size of 5.5 cm×3.8 cm to 8.0 cm×5.0 cm. The rated capacity of expanders placed at forehead was 150 to 300 mL with times of water injection of 1.5 to 2.0. Donor sites were directly sutured or reversely repaired by pedicled skin tube plasty. After operation, operation times and treatment time were recorded. The survival condition and complications of flaps and follow-up were observed.@*Results@#The patients each received 1 to 4 operation (s) with treatment time of 5 to 11 months. All flaps survived after operation. Among them, three flaps with perforating branches of internal thoracic artery had slight blood circulation disturbance at the distal end and were healed after conservative dressing change, etc. Pigment changes were observed at the distal end of thoracic internal artery perforator flaps in two patients in the later stage and was resected and repaired in the second stage. The patients were followed up for 5 to 18 months. The appearance and function of operation area were good with high satisfaction of patient.@*Conclusions@#The axial flap of adjacent artery perforator with vascular pedicle for repairing scar deformity of face and neck used directly or preexpanded can solve the problem of lack of normal skin around scar deformity without vascular anastomosis during the operation and with better appearance and function after operation. The donor site often can be directly sutured, but many operations often need to be completed for finishing whole treatment.
