Summary
Microimplant-assisted rapid palatal expansion (MARPE) therapy does not significantly alter intracranial pressure in late adolescents. Optic nerve sheath diameter measurements confirmed no significant changes during MARPE screw activations.
Area of Science:
- Orthodontics
- Neurosurgery
- Medical Imaging
Background:
- Microimplant-assisted rapid palatal expansion (MARPE) is used to treat posterior crossbite in post-pubertal individuals.
- Intracranial pressure (ICP) changes during MARPE therapy are not well understood.
- Optic nerve sheath diameter (ONSD) measured via ultrasonography (US) can indicate ICP fluctuations.
Purpose of the Study:
- To evaluate potential intracranial pressure (ICP) changes during active microimplant-assisted rapid palatal expansion (MARPE) therapy.
- To assess the impact of MARPE screw activations on the optic nerve sheath diameter (ONSD) in post-pubertal patients.
Main Methods:
- Fifteen post-pubertal patients undergoing MARPE therapy using the Maxillary Skeletal Expander (MSE) appliance were studied.
- Optic nerve sheath diameter (ONSD) was measured using ultrasonography (US) before and at intervals after the first and final MARPE screw activations.
- Vital signs and pain perception were also recorded during the procedure.
Main Results:
- A slight, non-statistically significant increase in ONSD was observed within one minute after screw activations.
- No significant difference was found between initial and final ONSD measurements throughout the active MARPE therapy.
- No significant changes in vital signs were noted during the procedure.
Conclusions:
- Active MARPE therapy does not cause significant intracranial pressure alterations in late adolescents.
- Ultrasonography measurement of ONSD is a reliable method for monitoring ICP during MARPE treatment.
- MARPE therapy is safe concerning intracranial pressure changes in the studied age group.

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...
