Phrenicotomy is a medical procedure that involves cutting the phrenic nerve, which controls the diaphragm. This is typically done to treat hiccups or as a last resort for certain medical conditions. Synonyms for phrenicotomy could include diaphragmatic nerve transection, phrenic nerve ablation, and phrenic nerve section. Other terms that may be used to describe this procedure include diaphragm paralysis surgery, diaphragm denervation, and phrenic nerve lesioning. Regardless of what it is called, phrenicotomy is a serious medical procedure that should only be done by a trained and experienced surgeon. It can have significant long-term effects on breathing and should not be taken lightly.
