摘要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 400-600ml skin dilator was inserted into the forehead and 50-100ml 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.
