Hemifacial spasm: treatment by posterior fossa surgery
Journal of Neurology, Neurosurgery, and Psychiatry
|September 1, 1978
Summary
Posterior fossa exploration effectively treated hemifacial spasm in nine patients, with eight experiencing complete relief. This microsurgical approach is recommended for hemifacial spasm, even without identifiable pathology.
Area of Science:
- Neurosurgery
- Neurology
Background:
- Hemifacial spasm (HFS) is an involuntary movement disorder affecting facial muscles.
- Surgical intervention is considered for medically refractory cases.
Purpose of the Study:
- To evaluate the efficacy and safety of posterior fossa exploration for treating hemifacial spasm.
Main Methods:
- Nine patients with hemifacial spasm underwent posterior fossa exploration.
- Microsurgical techniques were employed.
Main Results:
- Eight patients achieved complete resolution of hemifacial spasm; one experienced marked improvement.
- No mortality or significant morbidity was observed.
- Definite pathology was identified in only three cases.
Conclusions:
- Posterior fossa exploration is a safe and effective treatment for hemifacial spasm.
- The procedure's success may be attributed to microvascular decompression or induced perineural fibrosis when no clear pathology is found.
