Results of surgical treatment for growth hormone-secreting pituitary adenomas.

The results of surgical therapy for acromegaly were reviewed in a series of 175 patients treated between 1972 and 1983. Patients with prior surgery or radiation therapy were excluded from the study. Postoperative radiation therapy was given to 54 patients. The criterion of achieving a postoperative basal or glucose-suppressed growth hormone level of 2 ng/ml or less was used to indicate remission. Utilizing the most recently available growth hormone determinations, 90 (51.7%) of 174 patients were in remission. The actuarial probability of remission at 1 and 5 years after surgery was 48.8% and 62.7%, respectively. Tumor size and the preoperative basal growth hormone level were correlated with outcome. Surgical excision of a pituitary adenoma is the most effective therapy currently available for acromegaly.

Selective peripheral denervation for torticollis: preliminary results.

Herein we report the preliminary results in nine patients who have undergone selective peripheral denervation for spasmodic torticollis and have been followed up for at least 13 months. All patients had improvement immediately after surgical intervention, and the results have been maintained in five patients. In one patient who had recurrent torticollis, a second procedure in conjunction with injection of botulinum toxin has produced substantial improvement; however, follow-up was brief (6 months). No surgical complications occurred. We believe that selective peripheral denervation is safe and that it can benefit patients with torticollis who have not responded to other types of therapy. These favorable results confirm other published reports on the efficacy of selective peripheral denervation. Long-term follow-up, however, is necessary for determining the role of this procedure in the management of torticollis.
