“…The structure at the bottom of the septum pellucidum was identified as the rostral lamina (Figure 2). 16 Once the anterior commissure was identified, it was disconnected using bipolar or microforceps (Figure 1E). The third ventricle was observed only after the AC was completed (Figure 1F).…”

BACKGROUND:Corpus callosotomy (CC) is a palliative neurosurgical procedure for patients with intractable epilepsy and without resectable focal epileptogenic lesions. Anterior commissurotomy (AC) has been historically performed with CC. However, the efficacy and safety of adding AC to CC remain unknown.OBJECTIVE:To describe the surgical technique of extraventricular AC and retrospectively investigate its clinical efficacy and safety by assessing patients who underwent CC with and without AC.METHODS:AC has been added to CC at our institution since 2018. Fifty-five consecutive patients who received total callosotomy from 2016 to 2020 were included and categorized into 2 groups: 26 patients with additional AC and 29 patients without additional AC. Seizure outcome 1 year after surgery were compared between groups for assessing the efficacy of adding AC. The perioperative factors were compared for assessing the safety and feasibility.RESULTS:Seizure reduction rate (50% and 60%; P = .60) and disappearance of drop attacks (42% and 58%; P = .25) were not significantly different between CC and CC + AC groups. No statistical group differences were found in intraoperative estimated blood loss, number of days to first oral intake, duration of postoperative intravenous hydration, and length of hospital stay.CONCLUSION:Disconnection of the anterior commissure is a feasible and relatively safe procedure. This study failed to show the significant efficacy of adding AC to CC. However, further investigation is needed to prove its efficacy in ameliorating epilepsy.
