Clinicopathology Profile and Post-Microsurgical Outcome of Sphenoorbital Meningioma: Single Institution Experience.

Introduction: Meningiomas are among the most common types of intracranial neoplasm. Sphenoorbita meningioma usually affect anatomical and functional around the orbits. This study aimed to analyse the epidemiological distribution and clinical data of patients with sphenoorbital meningioma who underwent tumor resection microsurgery with a focus on surgical outcomes. Patients and Methodo: This is a retrospective descriptive study conducted in Dr. Cipto Mangunkusumo Hospital as a national referral hospital in Indonesia between 2018 and 2023. Epidemiological data and clinical status were collected through medical record.

Results: There were 66 patients included in this study, majority of patients were women (93.9%), with a femaleto- male ratio of 15.5:1. The mean age at tumor resection surgery was 44.68 ± 7.8 years old, with the majority of patients in the 41-50 age group (53.0%). Tumor resection in sphenoorbital meningioma presented fairlygood outcomes depending on the degree of resection, with optimum improvement in structural symptoms, such as proptosis (100%), but debatable results in functional symptoms, such as visual acuity (6.1% improvement and 83.3% stabilization).

Discussion: Sphenoorbital meningioma is a common intracranial neoplasm that can cause visual disturbances, proptosis, and other neurological symptoms. Surgical resection is the definitive treatment and the degree of total resection is commonly measured using the Simpson grading system.

Conclusion: Understanding patient outcomes is crucial to improve surgical techniques and reduce postoperative complications. This study provides valuable epidemiological and clinical data as a basic knowledge for further research about surgical management in sphenoorbital meningioma patients.
