Background: Penetrating brain injuries (PBIs) caused by non-missile objects are rare but associated with high morbidity and mortality. We report a series of three cases involving distinct mechanisms of injury, knife and wooden stick, highlighting the anatomical and infectious challenges of craniofacial trauma.

Case Presentations: Case 1: A 29-year-old male with a transfixing 16-cm knife injury. Death was immediate due to massive intracranial hemorrhage and brainstem involvement.

Case 2: A 25-year-old male with a trans-sinusoidal knife injury. Initial survival was followed by fatal meningitis three months post-injury, secondary to a persistent cerebrospinal fluid (CSF) leak.

Case 3: A 33-year-old male with an orbito-cerebral injury from a wooden stick. Despite surgical extraction, the patient succumbed to septic shock and cerebral abscess formation.

Conclusion: The prognosis of PBI is determined by the trajectory, the nature of the foreign body, and the management of delayed infectious complications. This series emphasizes the necessity of rigorous dural repair and long-term surveillance in surviving patients.
