“…These findings are generally similar to those in other studies 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13. The reoperation rate was 10.1%, which is within the range of rates reported internationally (6–23.8%) in studies of patients with variable etiology of ET and of different ages 2, 4, 7, 8, 9. We still do not have any data concerning the long-term (≥10-year) follow-up outcomes in the KSA, in this study 75% of cases were followed for ≥5 years.…”
