Transcervical thymectomy for thymoma in myasthenia gravis

The results of thymectomy performed through a transcervical approach in 37 myasthenic patients with thymomas is reported and compared with results in 97 patients who had thymomas removed through a transsternal approach. In 29 of the former patients the thymomas were unsuspected and found at the time of thymectomy, and in 8 a preoperative chest roentgenogram was suspicious for the presence of a tumor. In the transcervical group there were only 4 invasive thymomas, while in the transsternal group there were 32. In the transcervical group there was no evidence of recurrence in the patients with unsuspected thymomas, and one recurrence in the group with suspected thymomas. In the transsternal group eight patients had known recurrence or persistent disease. The transcervical approach seems appropriate for the removal of small thymomas discovered at the time of thymectomy or suspected from the preoperative work-up.
