Abstract:
Objective To provide an anatomical basis for repairing the defect of cervical tracheal wall with vascularized pectoralis major tendon flaps.Methods Thirty-two lateral thoracic necrotomies were studied for the following aspects.Measurement of pectoralis major tendons' length,width and thickness.Anatomy of thoracoacromialartery,pectoral branches:origin,distribution.Measurement of length of pedicle,rotated radius of flaps and length from recipient site.An imitative operation was undergone on a specimen of corpse.One patient was undergone the operation of repairing the 3.0 cm × 1.5 cm defect of anterior cervical trachea wall,accompanying with incision infection,with pectoralis major tendon flap.Results Length of pectoralis major tendon:(22.9 ± 0.9)mm.Width of tendon:(51.0± 2.4)mm.Thickness of tendon:(5.81± 1.35)mm.Length of pedicle:(89.3 ± 5.3) mm.The radius of pedicle pectoralis major myotendinous flap:(121.7± 8.2)mm.The distance from pivot point of flap to central point of recipient:(96.5 ± 8.9)mm.Patient possessed normal pronunciation,good appearance and no emphysema at 5 months' follow-up.Tracheal lumen,measured 2.6 cm in the anteroposterior dimension and 1.8 cm in the lateral dimension,showed no recurrence of obvious stenosis in cervical computed tomography at 3 month postoperatively.Conclusion Pedicle pectoralis major tendon flaps,originated from thoracoacromial artery pectoral branches can repair cervical tracheal wall defects effectively.
