What does cephalotomy mean?
Cephalotomy is a noun denoting the surgical cutting or dissection of the head. The term arises most often in the history of medicine, where it named a grim but once-necessary obstetric operation: when a fetus had died in the womb and its passage blocked labour, the cranium might be reduced so that delivery could proceed. With the development of safe caesarean section and modern obstetric care, this use became obsolete, and today cephalotomy survives chiefly in historical texts, medical dictionaries, and discussions of surgical terminology. Like many anatomical terms, it is built from Greek elements — kephalē, meaning 'head', and tomia, meaning 'a cutting' — the same roots that give us cephalic, cephalopod, and the many '-otomy' terms of surgery. Because it belongs to formal medical register rather than everyday speech, it is best used precisely and in context, where it conveys both technical accuracy and a window into how far surgical practice has evolved.
nounA surgical operation involving the dissection or incision of the head, historically referring especially to the reduction of a dead fetus's cranium to permit delivery when normal birth was impossible.
- Surgical dissection of the head, especially the historical obstetric procedure of reducing a dead fetus's cranium to enable delivery.
"Before the advent of safe caesarean section, cephalotomy was sometimes the only recourse in obstructed labour."
"The obstetrics textbook included a chapter on obsolete procedures such as cephalotomy."
"Derived from the Greek for 'head' and 'cutting', cephalotomy describes any surgical division of the head."
Standard English plural; rarely needed given the word's narrow, largely historical scope.
"The archive contained detailed accounts of cephalotomies performed in eighteenth-century lying-in hospitals."
Cephalotomy comes from Greek words meaning literally 'head-cutting' — one of many surgical terms that owe their precision to ancient Greek anatomy.

Etymology of cephalotomy
Cephalotomy derives from Greek kephalē, 'head', combined with tomia, 'a cutting' or 'incision'. It entered English through New Latin medical vocabulary, alongside the large family of '-otomy' surgical terms such as tracheotomy and lobotomy. Its closest relatives are other Greek-derived 'cephalo-' terms, including cephalic and cephalopod, all tracing back to the same root word for head.
How cephalotomy is actually used
A technical medical term of largely historical interest, encountered mainly in older obstetric literature and histories of surgery. It carries clinical rather than everyday connotations and should not be used casually.
Easily confused with cephalotomy
Craniotomy is an incision through the skull, typically to access the brain in a living patient, whereas cephalotomy refers to cutting apart or reducing the head itself, chiefly in historical obstetric practice.
A cephalopod is a marine mollusc such as an octopus or squid, sharing only the Greek root kephalē ('head') with cephalotomy.
