Five-year follow-up after neurosurgery complicated by facial neuropathy.

Background: Botulinum toxin A (BTA) injections are effective for facial neuropathy. However, there is insufficient number of studies devoted to long-term management of these patients.

Objective: To evaluate the effectiveness and safety of BTA therapy in patients with facial neuropathy after neurosurgical interventions.

[To the origins of surgery for acoustic neuromas].

Acoustic neuroma is one of the most common tumors of the posterior cranial fossa. Its removal is always a challenge for the neurosurgeon and the patient. The history of surgery for acoustic neuromas is inextricably linked with the history of neurosurgery in general.

Early results of intraoperative neurophysiological monitoring in surgical treatment of hemifacial spasm.

Background: Neurophysiological monitoring in surgery for hemifacial spasm has been used since the 1990s, when Moller et al. demonstrated the effectiveness of intraoperative assessment of lateral spread response (LSR) regarding postoperative outcomes. Currently, there are conflicting data on effectiveness and feasibility of this technique.

[Endoscopic fenestration of arachnoid cyst of posterior cranial fossa through third ventriculostomy].

Arachnoid cysts (AC) are spaces with cerebrospinal fluid covered with arachnoid membrane. Most cysts are supratentorial and only 10-12% of ACs are found in posterior cranial fossa. This disease is usually diagnosed in childhood.

[Treatment of petroclival meningiomas: current state of the problem].

Petroclival meningiomas (PCMs) are benign, slowly growing tumors. Surgery still remains the main treatment option for them. The desire for total resection of large extended PCMs often leads to the development or worsening of persistent neurological deficits.
