● The recommended surgical technique is BHC since in most patients it offers the highest treatment-to-complication ratio.
● The best treatment for high-risk patients could be the bedside Twist Drill Craniostomy (TDC) under local anesthesia.
● A craniotomy is the best surgical procedure for draining CSDH with a significant membrane, acute contribution, multiple recurrences, or calcification.
● After BHC, putting drainage in a closed system leads to a substantial reduction in the rate of recurrence.

• This clinical trial was conducted on patients candidate for anterior cerebral circulation aneurysm surgery during 2017-2018 in Rasul Akram Hospital, Tehran, Iran.
• Somatosensory Evoked Potential (SSEP) monitoring was performed during the surgery procedure.
• Totally 9 patients (9 aneurysms) were studied in this research.
• According to the results of this study and comparing them with similar researches in literature, neuromonitoring can be used as an index for examining tissue perfusion level of the brain and help to prevent accidental ischemic injuries of the brain followed by temporary clipping.

• Significantly higher SBSES scores in L.G. Kempe craniotomy were reported.
• No difference was found between the 2 groups in terms of hair follicular density.
• No difference was found between the 2 groups in terms of subjective patient satisfaction.

• We report 11 cases with patients presenting craniopharyngioma with intraventricular cystic portion inducing hydrocephalus.
• A cysto-ventriculostomy was performed in 9 patients and additional ETV (Endoscopic Third Ventriculocisternostomy) in 2 cases.
• The global outcomes were good in the 9 patients.
• It has advantages especially in practical conditions which do not always provide adequate safety conditions for complex microsurgical approaches.
