Welcome to SoniModul!

Focused Ultrasound Surgery
Against Functional Brain Disorders

We offer to patients suffering from chronic and therapy-resistant functional brain disorders, a sparing concept centered on millimeter-large and abnormally functioning brain targets, allowing bilateral treatments and absence of neurological deficits, and the exclusive use of the new focused ultrasound technology, which reduces most significantly the treatment risks and optimizes targeting precision.

Dear patients, families and colleagues,

I am retiring after 37 years of clinical and research activity in the field of functional neurosurgery. My last 14 years were spent in the framework of the SoniModul Center of Ultrasound Functional Neurosurgery, meeting and treating patients together with a great, efficient and dedicated team.

In spite of all our efforts, it has not been possible to find a solution for my succession. SoniModul will thus have to close end of January 2024. We regret very much not to be able to proceed helping patients, who came to us regularly and courageously, from near and far. A number of peer-reviewed publications allow colleagues to read about our experience and maybe develop further the work done.

Patients in close current interaction with us will be contacted.

I realize after all these years of neurosurgical activity how deep and constructive the contacts with patients and their families have been. I learned so much, not only about medicine but also about myself and what it all means to be a human being. I remain immensely happy about all good patient evolutions, and sad about the patients who could not be helped well enough. All in all, I leave the medical arena with a deep nostalgy, and much gratefulness to all persons I had the chance and privilege to meet along my medical path.

Targeting Accuracy

General Treatment facts

FUS interventions
Targets sonicated
Effects on neighboring structures
Neurological worsenings

Effects on neighboring structures (surrounding surgical targets) were partial and mostly transient.
Neurological worsenings were moderate and mostly transient and seen always in the context of preoperative reduced neurological states

Targeting Accuracies

Difference between the atlas target coordinates and the lesion coordinates,
as measured on 2 days post-operative MRI scans:

1 mm
in Medio-Lateral direction
1 mm
in Antero-Posterior direction
1 mm
in Dorso-Ventral direction
