Colliscalene triangle

Last revised by Craig Hacking on 18 Oct 2022

The colliscalene triangle is an important anatomical region of the neck, situated medial to the scalenus anterior muscle.

It should not be confused with the scalene triangle which is located posterior to the scalenus anterior muscle.
