Abstract Objective To investigate the Italian experience on the surgical and radiosurgical treatment of drug‐resistant epilepsy due to hypothalamic hamartoma (HH) in the period 2011–2021 in six Italian epilepsy surgery centers, and to compare safety and efficacy profiles of the different techniques. Methods We collected pseudo‐anonymized patient's data with at least 12 months of follow‐up. Surgical outcome was defined according to Engel classification of seizure outcome. Univariate analysis was performed to assess the risk of post‐operative seizures, categorized in dichotomous variable as favorable and unfavorable; explanatory variables were considered. Mann–Whitney or Chi‐squared test were used to assess the presence of an association between variables ( p < 0.05). Results Full presurgical and postoperative data about 42 patients from 6 epilepsy surgery centers were gathered. Engel class I was reached in the 65.8% and 66.6% of patients with gelastic and non‐gelastic seizures, respectively. Other than daily non‐gelastic seizures were associated with seizure freedom ( p = 0.01), and the radiological type presented a trend toward significance ( p = 0.12). Significance Endoscopic disconnection and laser interstitial thermal therapy are effective in the treatment of HH‐related epilepsy, with a tolerable safety profile. Both gelastic and non‐gelastic seizures can be treated, also in patients with a long history of seizures. Plain Language Summary This study collected data about 42 patients with HH‐related epilepsies. Endoscopic disconnection and laser therapy are both effective and safe in the treatment of hypothalamic hamartoma‐related epilepsies.
