Reconstruction of the mediastinal trachea with a tubed pectoralis major myocutaneous flap.

A young patient with a massive postirradiation recurrence of thyroid cancer invading the larynx and mediastinal trachea had been treated by resecting the larynx and trachea to within three rings of the carina. A mediastinal tracheostomy was avoided by using a tubed pectoralis major myocutaneous flap to replace the ablated trachea. The flap, transferred into the mediastinum subclavicularly, was connected to the tracheal stump and exteriorized as a cervical tracheostomy. This resulted in direct closure of the donor site and primary healing. Four years after the operation, the patient remains free of disease and is tolerating the neotrachea without difficulty or complications. The technique described is offered as an alternative to conventional mediastinal tracheostomy methods, which have acknowledged shortcomings.
