Comparison of Surgical Exposure and Outcomes Between the Subtonsillar and Infrafloccular Approaches in Microvascular Decompression for Hemifacial Spasm

Key Points

• The aim is to compare the surgical exposure and outcomes of the subtonsillar and infralfloccular approaches in microvascular decompression for hemifacial spasm.
• Comparison of surgical exposure between subtonsillar and infralfloccular approaches.
• Assessment of outcomes including auditory morbidity and nerve dissection efficiency.
• The subtonsillar approach improves inferior access for vessel manipulation.
• It reduces mastoid disruption compared to the infralfloccular approach.
• The subtonsillar approach is associated with lower auditory morbidity.
