Tracheal fenestration was first developed by Rocky and his co-workers as a procedure in management of pulmonary suppuration. One of the authors (I.H., 1965) reported that the surgery was successfully applied to cases of bilateral recurrent laryngeal nerve paralysis. Since that time we have found a wide variety of the indication of tracheal fenestration: the operative procedure has been satisfactorily applied for cancer of the larynx (when hemilaryngectomy was done), tumors of the pharynx, tumors of the trachea, laryngeal stenosis, head injury, and disturbance in breathing after cardiac surgery, as well as bilateral recurrent laryngeal nerve paralysis.
We have also noticed that a simple semicircular skin incision with the base cranial could be successfully employed instead of the complicated skin incision in Rocky's technique. Our simplified technique comprises a semicircular skin incision of three centimeter in diameter, seperation of strap muscles at the midline, dissection of the isthmus of the thyroid gland, quadrangular removal of the anterior wall of the trachea at the level of the third and fourth tracheal rings, and sutures of the skin and tracheal mucosa.
