BACKGROUND: Recovery time after corpus callosotomy (CC) is known to be longer in elderly than in younger patients. OBJECTIVE: To evaluate the relationship between patient age and recovery time of activities of daily living (ADL) after 1-stage complete CC. METHODS: This study included 41 patients (22 women; aged 13 months-34 years, median 7 years) who underwent 1-stage complete CC for medically intractable seizures with drop attacks, infantile spasms, and/or bilaterally synchronized electroencephalographic discharges between August 2009 and April 2019. The timing of restart of competence in 5 ADL categories and surgical outcomes were recorded. RESULTS: Patients (1) restarted speech at 2.2 ± 1.3 (mean ± 2 standard deviations; range 1-5) days, (2) restarted replying with their own name on request at 5.5 ± 8.6 (2-33) days, (3) restarted oral intake at 1.6 ± 1.7 (1-11) days, (5) discontinued intravenous feeding at 6.0 ± 3.0 (2-16) days, and (5) restarted ambulation or wheelchair movement at 5.8 ± 3.4 (2-10) days. Younger patients showed significantly (P < .0223) earlier recovery of ambulation or wheelchair movement, but no age difference was found in the other 4 ADL categories. Overall seizure freedom was achieved in 5 patients, excellent (>80%) seizure reduction in 11, good (50%-80%) seizure reduction in 5, and poor (<50%) seizure reduction in 20. CONCLUSION: Early ADL recovery after 1-stage complete CC is favorable in both young and adult patients. These findings, with good surgical outcomes, will encourage more positive consideration of 1-stage complete CC in both pediatric and adult patients.
