Current trends in vestibular schwannoma management at a referral center in Indonesia: A cross-sectional study with retrospective data collection

Background. Vestibular schwannoma (VS) is the most common benign brain tumor of the cerebellopontine angle. Due to its location, this pathology can create both focal and general deficits. The registry system for VS in Indonesia is developing, including in the author’s institution, which eventually shows a changing trend in managing VS. Methods. We retrospectively collected data from all patients diagnosed with vestibular schwannoma, based on histological or radiological results. Treatments included craniotomy and/or Gamma Knife Radiosurgery (GKRS) from 2018 to 2023. Results. Data from 88 patients were analyzed. The number of treated patients has increased annually. VS predominantly affects females (64%). The proportion between GKRS and craniotomy procedures also shifted throughout the year. Common symptoms included hearing loss (63.6%), disequilibrium (50%), and headaches (39.7%). The most common tumor size was medium (15-30 mm; n=37; 42%). Tumors that fell into the intrameatal and small (
