Methods： From June 2007 to June 2012, five cases of defects of the thoracic trachea were reconstructed by applying portions of deepithelialized myocutaneous flaps. The patients were 27-61 years old with 4 male cases and 1 female. The cervical trachea ranged in diameter from 4-8.5 cm with circumferences of approximately 1/3-2/5 of the bronchial circumference. Results： M1 five patients with thoracic tracheal defects after resection of a large tumor were cured of portions of deepithelialized myocutaneous flaps, with no tracheal stricture remaining and vomica successfully eliminated. During the first 1 to 3 months after the operation, bronchoscopy showed that the tracheal lumens were smooth, and the visible skin of the musculocutaneous flaps became gray and exhibited a small amount of white discharge. Conclusions： Despite this being a small series and short follow-up, this thoracic tracheal reconstruction with portions of deepithelialized myocutaneous flaps shows encouraging preliminary results and could be an alternative to other methods for the treatment of carefully selected patients with thoracic tracheal defects.展开更多

Methods: Different myocutaneous flaps were selected according to the location, peculiarity and etiological factor of wound. There were 28 cases of island pectoralis major island myocutanuous flaps, 34 cases of latissimus dorsi island myocutaneous flaps, 19 cases of trapizius island myocutaneous flaps and 17 cases of rectus abdominis island myocutaneous flaps in this report. Results: All 98 patients with challenging wound on cervico-thoracic region were successfully treated with this method without complications, and obtained functional and cosmetic effectiveness. Conclusion:Challenging wounds in cervico-nuchal region can be repaired with pertoralis major island myocutaneous flap, latissimus dorsi island myocutaneous flap and trapizius island myocutaneous flap, while challenging wounds in thoracic region can be repaired with latissimus dorsi island myocutaneous flap and rectus abdominis island myocutaneous flap. Satisfactory functional and cosmetic results can be obtained.展开更多
