The age of the patients varied from 18 to 43 years. All patients suffered from refractory epilepsy caused by focal lesions of the mesial temporal complex or temporal pole in dominant side. Postoperative pathology revealed neuronal-glial tumors in two patients, focal cortical dysplasia (FCD) of the temporal pole \u2013 in two patients, cavernous angioma \u2013 in one patient, and encephalocele of the preuncal area \u2013 in one patient.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st3\">\n<jats:title>Results: <\/jats:title>\n<jats:p>All patients underwent surgery satisfactorily. There were no postoperative complications except for homonymous superior quadrantanopia. This kind of visual field loss was noted in four cases out of six. During the follow-up period five patients out of six had Engel Class I outcome (83.3%). In one case, seizures developed after 1 month in a patient with FCD in the uncus (Engel IVA). After surgery, three out of six patients developed significant nominative aphasia. Two patients relative to the preoperative level demonstrated improvement in delayed verbal memory after MHT. Two patients showed a decrease level in delayed verbal memory. In preoperative period, visual memory was below the normal in one patient. Delayed visual memory in two cases impaired compared to the preoperative level.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st4\">\n<jats:title>Conclusion: <\/jats:title>\n<jats:p>MHT can be considered as an effective method of drug-resistant mesial temporal lobe epilepsy caused by tumors of the medial temporal complex. At the same time, MHT makes it possible to preserve memory in patients with structurally preserved hippocampus. However, MHT do not guarantee the preservation of memory after surgery.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_350_2021","type":"journal-article","created":{"date-parts":[[2021,7,27]],"date-time":"2021-07-27T07:47:19Z","timestamp":1627372039000},"page":"372","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Multiple
