Summary
This study introduces a mini-open microsurgical technique for partial corpus callosotomy in epilepsy patients. The safe and efficient procedure reduces craniotomy size and operating time, making epilepsy surgery more accessible.
Area of Science:
- Neurosurgery
- Epileptology
Background:
- Corpus callosotomy is a standard treatment for drug-resistant epilepsy.
- Minimally invasive techniques exist but are often resource-intensive.
- A novel mini-open microsurgical approach is presented.
Purpose of the Study:
- To describe and evaluate a mini-open microsurgical technique for partial corpus callosotomy.
- To assess the safety, efficiency, and accessibility of this approach.
Main Methods:
- A mini-open technique using a parasagittal incision and small craniotomy.
- Retractorless interhemispheric dissection guided by neuronavigation.
- Analysis of pre- and post-operative imaging to assess craniotomy size and disconnection.
Main Results:
- 38 partial callosotomies were performed in 24 patients over 5 years.
- Craniotomy size decreased over time with technique adoption.
- Mean operating time was 99.6 minutes with no reported complications.
Conclusions:
- Mini-open partial callosotomy is a safe and effective epilepsy surgery.
- The technique minimizes surgical morbidity and can be implemented in standard neurosurgical units.
- This approach enhances epilepsy surgery accessibility in resource-limited settings.
