Abstract

Introduction: The intricate microsurgical anatomy of the cranial nerves plays a pivotal job in guiding neurosurgical approaches and procedures within the complicated landscape of the cranial cavity.


Objectives: The main objective of the study is to find the microsurgical anatomy of the cranial nerves and its implications for neurosurgical approaches and procedures.


Methodology of the study: This prospective observational study was conducted at General hospital, Lahore from March 2023 to January 2024. Data were collected from 80 patients. Patients of varying ages and demographics with diverse pathologies affecting the cranial nerves were included in the study. Clinical data, radiological imaging studies, intraoperative photographs, and surgical records were retrospectively reviewed for each patient. Information regarding the specific cranial nerves involved, anatomical variations, pathological conditions, surgical approaches employed, intraoperative findings, and postoperative outcomes were extracted from medical records.


Results: Data were collected from 80 patients according to inclusion criteria of the study. Mean age of the patients was 58.01±12.5 years and out of 80 patients there were 44 (55%) male patients. Tumors were present in 48 (60%) patients.The trigeminal nerve (CN V) was most commonly affected, accounting for 30% of cases, followed by the facial nerve (CN VII) at 25% and the vestibulocochlear nerve (CN VIII) at 20%. Notably, multiple nerve involvement was observed in 15% of cases, indicating the complexity and multifaceted nature of cranial nerve pathologies encountered in neurosurgical practice.


Conclusion: It is concluded that understanding of microsurgical anatomy is paramount in guiding neurosurgical approaches for cranial nerve-related pathologies. Tailored surgical interventions, informed by intricate anatomical considerations, yield favorable postoperative outcomes while mitigating the risk of iatrogenic complications.
