Summary
This study details a rare case of intracranial condylar dislocation to the middle cranial fossa. It identifies a predisposing factor for this idiopathic condition, offering new insights into temporomandibular joint disorders.
Area of Science:
- Neurology
- Orthodontics
- Maxillofacial Surgery
Background:
- Intracranial condylar dislocation to the middle cranial fossa is an exceptionally rare condition.
- Previous cases are often linked to glenoid cavity erosion from joint prostheses or trauma.
Observation:
- This report presents a unique case of idiopathic intracranial condylar dislocation.
- The patient experienced nonfunctional limitations due to the dislocation.
Findings:
- A novel predisposing factor for idiopathic intracranial condylar dislocation to the middle cranial fossa was identified.
- This finding expands the known etiologies of this rare condition.
Implications:
- The identified predisposing factor may aid in diagnosing and managing similar idiopathic cases.
- Understanding the etiology is crucial for preventing functional limitations and improving patient outcomes.

01:14Increased Intracranial Pressure l: Introduction
Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...
01:29Increased Intracranial Pressure ll: Pathophysiology
Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
