Application of Frontotemporal Expanded Flap with Bilateral Superficial temporal vessels in Repair of Large Area Scar Contracture in Face and Neck

Objective To summarize the clinical experience of frontotemporal expanded flap with bilateral superficial temporal vessels in repairing large area scar contracture in face and neck.Methods 14 patients with facial and Cervical scar contracture in our hospital were taken as the research object.With bilateral superficial temporal vessels as pedicles,a 400-600 ml skin dilator was inserted into the forehead and 50-100 ml skin dilator was inserted into the two temporal parts respectively.Within 3-4 months,the water injection volume reaches 2 times of the dilator volume.After maintaining for one month,skin flap transplantation was performed.The frontal flap was reserved for hairline reconstruction,and the flap was cut to cover the area after facial and Cervical scar release to reconstruct the jaw-neck angle.The pedicle division and pedicle trimming were performed 3-4 weeks after operation.Results All the 14 patients completed the operation successfully.The flap expansion time is 5-6 months.The expanded skin flap covers an area of 26 cm×9 cm-42 cm×16 cm,and all the skin flaps survived after operation.Among them,2 patients suffered from flap congestion after flap transplantation.Follow-up for 6-12 months showed that the color and texture of the skin flap were similar to those of facial skin,with natural transition and no obvious bloating.The angle between the lower jaw and the neck is about 90.The anterior flexion,posterior extension,lateral flexion and rotation of the neck are obviously improved compared with the anterior,and the posterior extension is close to normal.Conclusion Frontotemporal expanded flap with bilateral superficial temporal vessels is suitable for patients with large-area scar contracture in face and neck that cannot be repaired after expansion of adjacent local normal tissues.

The therapeutic effect of expanded scalp flaps pedicled with the superficial temporal vessel for the reconstruction of the large facial skin scar

Objective To investigate the therapeutic effect of expanded scalp flaps pedicled with superficial temporal vessel in the repair of facial skin scars.Methods From May 2017 to October 2018,4 patients with facial skin scars were treated with expanded scalp flaps pedicled with superficial temporal vessels and laser hair removal.All patients were followed up for at least 6 to 12 months.Results The flaps of all 4 patients survived well,and the color,texture and thickness of the flaps matched well with the surrounding skin tissue.Conclusion Expanded scalp flaps pedicled with superficial temporal vessel is a good option for repairing facial skin scars,which is worthy of clinical application.

The relationship of tension and blood flow of the expanded pedicled fasciocutaneous flap in pig

Objective To evaluate the effect of wound closure tension on the blood flow of the expanded pedicled fasciocutaneous flap,so as to find the best tension for the blood supply of the flap.Methods 8 piglets,aged 9-12 months,were used.On
