Objectives: This study aimed to investigate the association between intracerebral aneurysms and cranial nerve (CN) palsies, focusing on nerves other than the oculomotor nerve. It sought to determine the prevalence, risk factors, and clinical outcomes of these nerve palsies and compare the effectiveness of microsurgical clipping versus endovascular coiling in restoring nerve function. Methodology: Following PRISMA guidelines, a comprehensive literature search was conducted using databases like PubMed, Scopus, and Google Scholar, covering studies from 1975 to April 2024. The inclusion criteria targeted patients with non-oculomotor nerve palsies diagnosed with cerebral aneurysms. Studies published before 1975 and non-English studies were excluded. Data extraction included study design, patient characteristics, and intervention outcomes. The Joanna Briggs Institute and Newcastle-Ottawa scales were used to assess study quality. Data were synthesized narratively and statistically analysed using SPSS v27. Results: The analysis included 47 patients (53.2% female, mean age 44.8 years). The internal carotid artery (ICA) was the most common aneurysm site (44.7%), and the abducent nerve (CN VI) was most frequently affected. Ruptured aneurysms had better recovery outcomes (88.9%) than unruptured ones (66.7%). Hypertension was present in 9.2%. Unilateral aneurysms were seen in 80.9%, with 76.6% having a single nerve palsy. Non-ruptured aneurysms accounted for 58.1%, and ruptured for 41.9% of associated cranial nerve palsies. Treatment included microsurgical approaches (42.6%), endovascular approaches (34%), combined approaches (6.4%), and conservative management (17%). Recovery of the palsy was observed in 75.6%, with endovascular procedures showing higher recovery (93.3%) compared to conservative treatment (28.6%). Conclusion: Intracerebral aneurysms are significantly associated with non-oculomotor CN palsies. Endovascular procedures yield higher recovery rates than conservative management, particularly in ruptured aneurysms. Timely and appropriate treatment is crucial for improving nerve function recovery in these patients. [ABSTRACT FROM AUTHOR]
