[Surgical treatment of pineal and tectal tumors from the subtentorial and supracerebellar approach].
The results of operative treatment of pineal and tectal tumours by infratentorial, supracerebellar approach were presented. There were 15 patients with pineal and 2 with tectal tumours. Clinical symptoms of the disease were as follows: signs of intracranial hypertension, tectal lesion, impairment of gait and hypoacusis. Diagnostic procedure included CT, MRI, and panangiography investigation. Application of infratentorial, supracerebellar approach enabled total resection of tumours in 14 patients (82.3%) and subtotal in 2 patients (11.8%) In 1 patient we managed to do only diagnostic biopsy (5.9%). This approach makes possible removal of pineal and tectal tumours growing in the midline toward the anterior part of III ventricle and also posterior fossa. The advantage of this approach is fact that the operation takes place below the vein of Galen. Drooping by gravity cerebellum creates enough places for microsurgical operation. During control investigation 13 patients (76%) had no announce any complaints and were without neurological disorders.
