Abstract
Background
The pathogenesis of Meige's syndrome (MS) remains unknown, posing a challenge for clinicians. The current classification system for MS causes confusion and difficulty in selecting target nerves for cranial nerve radiofrequency therapy. Therefore, to simplify the process of choosing radiofrequency therapy for MS, we suggest reorganizing the syndrome based on the affected cranial nerves.
Methods
The new classification of MS, which is based on the cranial nerves responsible, is more aligned with the requirements of radiofrequency therapy. Start by identifying the initial frequency of spasms from the patient's clinical symptoms, including muscles such as the frontal, orbicularis oculi, buccinator, orbicularis oris, latissimus, temporal, masseter, medial and lateral pterygoid, pharyngeal, lingual, sternocleidomastoid, and trapezius. Then, determine the involved cranial nerve based on the muscle's nerve innervation.
Results
The 117 MS patients were categorized into different groups based on their cranial nerve involvement: 73.50% were classified as the facial nerve type, 5.13% as the trigeminal nerve type, 2.56% as the sublingual nerve type, 0.85% as the glossopharyngeal nerve type, 4.27% as the accessory nerve type, and 13.67% as multiple groups of the cranial nerve complex.
Conclusions
The current classification of MS, which is based on clinical symptoms, does not make it easy to choose the target nerves for MS radiofrequency treatment. However, reclassifying MS according to the affected cranial nerves could simplify the process of radiofrequency treatment for MS.
