Methods of surgical treatment of patients with skull base meningiomas using high intensity infrared laser radiation (ND-YAG laser) at a wavelength of 1.06 micron were developed. The paper presents results of Nd-YAG laser application in skull base meningioma removal with assessment of its efficacy as compared with conventional surgical methods.Π Π°Π·ΡΠ°Π±ΠΎΡΠ°Π½Ρ ΠΌΠ΅ΡΠΎΠ΄Ρ ΠΎΠΏΠ΅ΡΠ°ΡΠΈΠ²Π½ΠΎΠ³ΠΎ Π»Π΅ΡΠ΅Π½ΠΈΡ Π±ΠΎΠ»ΡΠ½ΡΡ

Influence of the high-power ion-beam irradiation of a hydroxyapatite target on the properties of formed calcium phosphate coatings
The physical-mechanical of properties of biocompatible calcium phosphate coatings deposited onto titanium and silicon substrates from erosion materials, which are generated by irradiating hydroxyapatite (synthetic and natural) targets by means of the high-power pulsed ion beam of a Temp-4 accelerator, are investigated. A calculation technique for predicting the rate and energy efficiency of deposition using pulsed ion beams is proposed. Their characteristics are analyzed as applied to the formation of calcium phosphate coatings

Despite a significant advance in microsurgery of the parasagittal brain meningiomas the problem of its surgical treatment is not closed at the present time. This is due to the fact that parasagittal meningiomas can ingrow to the sinus lumen. In this cases the possibility of tumor resection using conventional techniques is limited. Attempts at the tumor radical removal lead to a massive operating blood loss, a stable severe neurological deficit and decrease the quality of life. This results in high recurrence rate of parasagittal meningiomas also. The paper presents the results of ND-YAG laser use in the removal of parasagittal meningiomas with assessment of its application efficacy as compared with conventional techniques.ΠΠ΅ΡΠΌΠΎΡΡΡ Π½Π° Π·Π½Π°ΡΠΈΡΠ΅Π»ΡΠ½ΡΠ΅ Π΄ΠΎΡΡΠΈΠΆΠ΅Π½ΠΈΡ Π² ΠΌΠΈΠΊΡΠΎΡ
