Surgical Outcomes in Cerebellopontine Angle Tumors: A Retrospective Analysis of 30 Cases

Introduction: Cerebellopontine angle (CPA) tumors present unique challenges due to their complex anatomy and proximity to critical neurovascular structures. This study aimed to analyze the clinical, demographic, and radiological characteristics of CPA tumors, identify pathological types, assess surgical resectability, and evaluate postoperative outcomes. Methods: We conducted a retrospective analysis of 30 patients who underwent surgical intervention via the retrosigmoid suboccipital approach for CPA tumors at Sadar Vallabh Patel Medical College, Ahmedabad, between May 2021 and May 2024. Results: Vestibular schwannomas constituted the majority (73.3%) of tumors, with most cases presenting in the third to sixth decades of life. Common symptoms included sensorineural hearing loss (83.3%), tinnitus (70%), vertigo (56.6%), headache (30%), and gait disturbance (33.3%). Total tumor resection was achieved in 76.6% of cases, with facial nerve preservation in 86.7% [5]. Postoperative complications included CSF leak (20%), meningitis (10%), hematoma (10%), residual tumor (23.3%), facial nerve paresis (13.3%), and one death (3.3%). Conclusion: The retrosigmoid approach remains a valuable technique for CPA tumor management. Our findings emphasize the importance of individualized surgical planning, careful preoperative assessment, and comprehensive postoperative care to optimize patient outcomes
