The suffix [-(o)cele] arises from the Greek [κήλη] meaning "dilation" or "pouching". In medical terminology this suffix is used to mean "hernia", "bulging", or a "dilation". In older times a synonym was used for hernia: "rupture".
Dr. Aaron Ruhalter would state the proper description for an "ocele" is that of a prolapse, that is, a herniation without a hernia sac.
Examples the use of [ocele] are:
- Orchiocele: The prefix [orchi-] means "testicle" or "scrotum". Refers to a scrotal or testicular bulging, a scrotal hernia
