The application value of intraoperative lateral spreading response monitoring during microvascular decompression in patients with primary hemifacial spasm.

ABSTRACT:

Background

The application value of intraoperative lateral spreading response (LSR) during microvascular decompression (MVD) is always disputed. The current study aimed to explore the predictive value of intraoperative LSR monitoring for the long-term outcome in patients with primary hemifacial spasm (pHFS).

Methods

The data from 312 pHFS patients were retrospectively reviewed. The zygomatic LSR (ZYG-LSR) and mandibular LSR (MAN-LSR) monitoring were performed during surgery. The correlations of ZYG-LSR and MAN-LSR disappearances with patients' long-term outcomes (one year after surgery) were retrospectively investigated. Consequently, binary logistic regression analysis was applied to explore their predictive value. Finally, the implications of their combined utilization for
