Surgery for tentorial meningiomas in 37 patients demonstrated a 2.7% mortality rate. Complete tumor removal was achieved in most cases, with a focus on appropriate preoperative studies and surgical techniques for long-term results.

Area of Science:

  • Neurosurgery
  • Neurology
  • Oncology

Background:

  • Tentorial meningiomas are tumors arising from the tentorium cerebelli.
  • These tumors can present with varied neurological symptoms and require specific surgical approaches.
  • Long-term outcomes and surgical experiences with these rare tumors are important for clinical practice.

Purpose of the Study:

  • To report the surgical experience and long-term results of patients with tentorial meningiomas.
  • To analyze the efficacy of different surgical techniques based on tumor location.
  • To evaluate the complication and mortality rates associated with the surgical management.

Main Methods:

  • Retrospective review of 37 patients with tentorial meningiomas treated between 1972 and 1993.

  • Classification of tumors into medial, lateral, and falcotentorial subgroups based on attachment site.
  • Description of surgical approaches including temporal, temporooccipital, parietooccipital, suboccipital craniectomy, and combined approaches.

    • Main Results:

    • Headache and gait ataxia were the most common presenting symptoms.
    • Signs of elevated intracranial pressure and cerebellar deficits were frequent neurological findings.
    • Total tumor removal was achieved in 31 patients (83.8%), with a 2.7% mortality rate.

    Conclusions:

    • Surgical management of tentorial meningiomas can achieve good long-term results with acceptable morbidity and mortality.
    • Tailoring surgical approaches to tumor location is crucial for successful resection.
    • Careful preoperative evaluation and surgical technique are essential for optimizing patient outcomes.
