Neurosurgeons treat nonfunctioning pituitary adenomas by surgical resection. Based on the adherence of the tumor to the normal pituitary gland, operative risks may include hormone replacement therapy for postoperative hypopituitarism with gross total resection that injures the gland or recurrent tumor with subtotal resection and purposeful avoidance of gland manipulation. None of the patients presented in this article had a preoperative preference regarding extent of resection. This study aimed to evaluate postoperative patient preferences regarding extent of resection. ⋯ Although patients may not have the preoperative insight or experience to have a strong conviction regarding the extent of adenoma resection, the consequences following surgery clearly influence their preference. Most patients in our study, including patients with gross total resection and especially patients who experienced side effects of steroid therapy, preferred subtotal resection with the chance of tumor recurrence over hormone replacement therapy.

We sought to reclassify the "anatomic risk zones of colloid cysts" as proposed by Beaumont et al, by proposing newer landmarks, and to assess predictive value for the risk of occurrence of hydrocephalus with the new classification compared with the old. ⋯ Symptomatic colloid cysts are more likely to develop hydrocephalus and sudden acute deterioration. The colloid cyst risk score is a step towards objective decision making, with scope for modification such as the one that we have attempted with new zone classification to achieve superior prognostic ability.

Inserting cerebrospinal fluid diversion devices such as external ventricular drains (EVDs) and ventriculoperitoneal shunts (VPSs) is a critical procedure. Unfortunately, complications such as catheter misplacement, dislocation, or infection can occur. Various surgical strategies aim to reduce these risks. One recent innovation is the "catheter-locking device-assisted" technique for EVD surgery. In this study, we examined its application in a larger group of cases encompassing both EVDs and VPSs over a 30-month period, with a focus on these complications. ⋯ The "catheter-locking device-assisted" technique may significantly decrease the occurrence of the most common EVD complications and can also prove beneficial in VPS surgery. However, further investigation is necessary.

Clipping of aneurysms located in the anterior communicating artery (AcomA) is considered a critical surgical procedure for neurosurgeons worldwide because of the complexity of the surgical area. The present study was conducted to discuss the importance of the geometric curvatures and the direction of the dominant A1 artery and their impact on aneurysmal growth direction and choice of side selection of the pterional surgical approach side. ⋯ A1 direction is an important additional factor that is to be considered for side selection when deciding pterional exposure of A1 bifurcation aneurysms. Accessing the contralateral dominant ascending A1 has better visualization of the neck than entering from an ipsilateral approach, especially if the ipsilateral A2 was posterior to the neck.

Meningiomas display diverse biological traits and clinical behaviors, complicating patient outcome prediction. This heterogeneity, along with varying prognoses, underscores the need for a precise, personalized evaluation of postoperative outcomes. ⋯ The study successfully demonstrated the potential of machine learning models in predicting short-term adverse postoperative outcomes after meningioma resections. This approach represents a significant step forward in personalizing the information provided to meningioma patients.
