The hamulus is always a fun find when I’m working with the students on interpretations as it really forces them to recall anatomy beyond just the maxilla and mandible. The hamulus is a small bony hook that projects off the medial pterygoid plate of the sphenoid bone (that’s a tongue twister). This is typically captured on intraoral images with either excessive distal angulation or if your patient isn’t a gagger – you got the image sensor extremely far back in their mouth.
The hamulus presents as an obliquely angled radiopaque entity directly distal to the maxillary tuberosity.
Here’s a fun example where it was visualized on a pantomograph.
