Plural form of ganglionectomy; multiple surgical procedures in which ganglia are removed from the nervous system.
From ganglionectomy (ganglion + Greek 'ektome' meaning cutting out or excision) plus the plural suffix -ies. Medical plural conventions change -y to -ies when pluralizing.
Surgeons perform ganglionectomies for severe chronic pain conditions—they literally cut out the nerve relay station causing the pain, like disconnecting an alarm that won't stop ringing!
