Multiple fractures of the hyoid and thyroid cartilage are more common in strangulation (especially manual) than in hanging, but they are not rare in hanging either—particularly in older adults.Hyoid fracture rates (the most compared number)Classic review figures (Ubelaker and later summaries):Hanging: roughly 6–20% (some older or less thorough studies much lower; careful dissection studies higher)
Ligature strangulation: 13–54%
Manual strangulation (throttling): 17–71%
One small series found hyoid fractures in 100% of 4 manual-strangulation cases versus ~21% of hanging cases. An Indian series reported 2.8% in hanging, 25% in ligature strangulation, and 50% in throttling.

So a broken hyoid is more frequent in homicide strangulation than in hanging, but it still happens in a meaningful minority of hangings.Combined / multiple fracturesThis is closer to Epstein’s pattern (1 hyoid horn + both thyroid superior horns).In hanging series with careful exam:Combined hyoid and thyroid fractures: commonly 16–23% of all hanging cases in larger prospective or well-dissected studies (Nikolić 16.2% of 557; Zátopková 23% of 178).
Isolated thyroid is usually the single most common finding in hanging.
One German series of 109 hangings found:1 fracture: 38% of those who had any fracture
2 fractures: 37%
3 fractures: 15%
all four horns broken: 10%
So three fractures occurred in about 10% of all hanging cases in that series. Other thorough studies report 0–6 fractures per hanging case.

In strangulation, injuries are generally described as more extensive: more fractures, more hemorrhage, and a higher chance of involving both structures plus the cricoid. Cricoid fractures are rare-to-absent in hanging and seen in 5–20% of homicide strangulations, which is why some authors treat a cricoid fracture as more suggestive of homicide. Epstein had no cricoid fracture.

Bottom line on “multiple”Any hyoid or thyroid fracture: more common in strangulation than hanging.
Multiple (2+) or combined hyoid + thyroid: still more common in strangulation, and the injuries tend to be more numerous and accompanied by more soft-tissue hemorrhage.
Three fractures of the exact type Epstein had do occur in documented suicidal hangings, especially in people in their 60s whose hyoid and thyroid are ossified and brittle. They are not “never seen” in hanging.
The frequency difference exists and is real, which is why Baden highlighted it. It is not large enough or specific enough by itself to distinguish hanging from strangulation. Location of the breaks, presence/absence of cricoid injury, hemorrhage pattern, ligature mark geometry, and scene findings matter more than the raw count of fractures.
