Advantages and disadvantages of the definitive surgical options for a entrapped temporal horn.

Table 1: Advantages and disadvantages of the definitive surgical options for a entrapped temporal horn.

Surgical option	Advantages	Disadvantages	Major indications
Ventriculoperitoneal shunting	Well demonstrated results Intracranial pressure relieve High effectiveness	Shunt dependency Shunt relative complications Possibility of abdominal spread in malignant tumors	Suitable for all cases
Frontal to temporal shunting	No risk of malignant cells spread outside the head	Limited in displaced or collapsed frontal horn Tumor growing can displaced the shunt	Favorable frontal horn anatomy
Endoscopic ventriculocisternostomy	No risk of malignant cells spread outside the head Can be used in cases of infection	Possibility of spontaneous ventriculostomy closure or after radiotherapy Neuronavigation dependent	Favorable anatomy Biopsy necessity
Endoscopic ventriculocisternostomy with a stein placement	No risk of malignant cells spread outside the head Less risk of disfunction	Theorically more risk of infection than in the endoscopic ventriculostomy Tumor growing can displaced the shunt Risk of migration Neuronavigation dependent	Favorable anatomy Biopsy necessity
Temporal tip removal	No risk of malignant cells spread outside the head	More invasive procedure	Alternative to endoscopy in cases that requires a biopsy
Etiologic treatment	Restores the cerebrospinal fluid physiology	Risk of recurrence	Only for benign tumors which can be completely resected
