Long-term results of 26 patients suffering from syringohydromyelia are reported. The patients underwent laminectomy and myelotomy with marsupialisation of the intracord cavity. Two different long term objective examinations have been performed demonstrating favorable results in 65% of patients at the first examination (mean 8 years following the operation) and in 60% of these at a second examination (mean 14 years following the operation). The limitations of posterior fossa decompression and other surgical procedures have also been discussed. The absence of surgical mortality and the length of follow-up period of this series supported the conclusions that laminectomy and myelotomy with marsupialisation of the intracord cavity represents a reliable method to relieve the effects of associated foramen magnum abnormalities avoiding posterior fossa surgery.
